Below are specific topics we’re bringing for you today:

Problem 1: How to fix Galaxy S8 moisture detected error, won’t charge due to moisture detected error

My new Samsung S8 immediately for no reason told me to shut it off due to moisture in USB…so I did for a few hours….then it was doing nothing when I went to turn it on so I did what most would with an older phone sat it in rice for a day…then I turned it on and it would come on with a brand new fast charger and showed a battery with an wall outlet picture under it so I check my cords an outlets.. on some other chargers it buzzed and buzzed repeatedly…..eventually after messing with it check water damage and such it came in and acted as if it was downloading something so I let it try …hole bother day goes by nothing happens…i’ve watched Youtube videos read forums and searched everywhere I’m stuck what do I do??? — Meganborecky03

Solution: Hi Meganborecky03. You have come to the right place.  If your phone keeps showing moisture detected error, we have a few fixes for your to try below. This error message usually shows up if the system detects moisture or water in the USB charging port. It doesn’t mean that the phone is damaged. It only indicates that the device blocks charging via USB charging port to prevent shorting other components.

Moisture Detected Fix #1

With that said, usually this error occurs when you are charging your phone while the phone is off.  As simple as this may sound, but simply turn on your phone first (or reboot your phone) and then plug in the charger.  It’s simple as that.  The moisture detected error typically show up when you try to charge the phone while the phone is off.

Moisture Detected Fix #2

If your phone is out of battery and you cannot turn on the phone first prior to charging, then try holding the power button and volume down at the same time, and while holding both buttons, plug in the charger, you should see phone load up with the last bit of juice.

Moisture Detected Fix #3

And if you’re still getting the error, the last thing you can do is to take advantage of the wireless charging function.  You would likely have to pick up a new wireless charger if you don’t already have one.

Moisture Detected Fix #4

Here’s a low tech solution, take a Q-Tip and clean around the charging USB port to make sure it’s completely dry and dust free.  Also try using a blow dryer at low heat to blow around and dry out the area.  You might think this is so obvious and simple, but it has worked for several of our readers!

Moisture Detected Fix #5

By the way, you may continue to get this error over and over, even if your phone have not come near any water in days.  What we’ve found is that you can try this:

  1. go to apps settings
  2. go to system apps
  3. USB Settings
  4. Storage
  5. clear data
  6. reboot phone

Problem 2: Galaxy S8 charger won’t go all the way in to the charging port

Hi. I recently had an upgrade to the Samsung S8 and twice now the charger jack plug has stopped going in to my phone to allow it to charge. i only ever use the charger that was supplied and it worked fine for 2 weeks, then stopped. i had a complete replacement and the same thing has happened this morning. I can get the jack plug to go in, so it slow charges but that is it. There is no debris or anything in the charger jack plug or the phone so im at a loss Please help i am a nurse and need my phone and find it unacceptable to have this problem happen again. Thanks. — Cheryl

Solution: Hi Cheryl. Your problem is hardware related so you don’t want to do anything to damage the charging port. There may be a bent pin in the port that causes this problem. We know it’s hard to really see the inside of the port without the aid of some form of magnification so we suggest that you let a professional take a look at it. If the device is covered by a replacement warranty, we suggest that you demand for a new phone instead of going through repair.

Problem 3: Galaxy S8 won’t send SMS to random contacts

I sent 6 text messages yesterday morning (Wed 5am) to my close family and friends. I text them regularly. and all failed and I cannot resend them either because they fail. However I can send messages to my husband (I text him all the time) and random friends. I even deleted their contact info and re-entered them in hopes that would help but it didnt. I have also turned my phone off for an hour in hopes that would help–it didn’t. — Storm

Solution: Hi Storm. The first move that you want to do here is to ensure that this is not app-related by wiping the cache and data of the messaging app. Here’s how to do that:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, look for the messaging app and tap it.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.
  6. Try wiping the cache first and observe how messaging works. If the problem stays, do the Clear Data option.

Tapping on Clear Data button deletes all your conversation threads so if you want to keep a copy of some, make sure to back them up ahead of time.

Another good thing to do in this case is to try using another messaging app. Doing so will help you identify if the problem is due to a bug in the current app or not. There are many free messaging apps that you can use like Google Hangouts or Facebook Messenger so just take your pick.

If the problem remains regardless of the messaging app, contact your carrier. The problem may lie on their end. Even if not, they’re still obligated to help you fix the problem though.

Problem 4: Galaxy S8 screen becomes totally black when Maximum Power Saving Mode is enabled

Yesterday, i turned my phone onto Maximum Power Saving mode through a notification. Now when phone turns on, i see boot screen, but screen is black after loading. If i press the Bixby button, a special Android notification pops up at bottom that can’t use Bixby in Maximum Power Saving Mode. I rebooted and charged it, no help. I can load it into recovery mode and it shows the screen fine. i tried wiping the cache, but no help. If i try loading into Safe Mode, i have same issue as normal, it’s a black screen, but says ‘Safe Mode’ at the bottom left. But i can’t see anything so i can’t uninstall anything. I tried ringing the phone and trying to answer it by swinging across, but that doesn’t work. Thanks for your time. — Vinnie

Solution: Hi Vinnie. Is it possible that you may have simply set screen brightness to the lowest setting? We don’t know if we understand your concern correctly as we haven’t heard or experienced this problem ourselves. We tried replicating your case in our own S8 and everything works fine, even if screen brightness is at its lowest. We suggest that you do a factory reset via Recovery mode and see how it goes from there. Otherwise, just stay away from Maximum Power Saving mode at this time until we can find more information about this problem. We’re going to update this post once we have an effective solution.

Problem 5: Galaxy S8 stops charging after charging port got wet, moisture detected error showing up

Hi. I saw Samsung’s commercial opening the Galaxy S8 from the box under water in a shark cage and then recording the sharks. So i put my phone in the water at the beach yesterday for 10 seconds. It’s still working but the charging port says moisture detected and it will not charge. It’s been 24 hours. Is the phone water proof or not? I bought a wireless charging port. — Heather

Solution: Hi Heather. We’ve seen the commercial too and we say it’s a bit extreme given the fact that the phone is not technically water proof. It’s only water-resistant in up to 5 feet (1.5 meters) of water for up to 30 minutes and even so, we won’t tell you to intentionally dunk your $700 phone in water. That’s because water-resistance protection is simply not water proof protection. Period. If you want to see the difference between water resistance and water proof protection, do some little Google search.

Now, for your main problem (well It’s not really a problem), you don’t have to worry at all. Try the steps we mentioned above to fix moisture detected error for Galaxy S8.

Problem 6: Galaxy S8 icon notifications for SMS won’t show, first call attempt always goes to voicemail

I have a new Galaxy S8 and I’m not receiving text notifications at all when the screen is unlocked or when it is locked. I do not care about notification sounds; I’m not getting the icon notifications, which I care about. I double-checked my notification settings, and messages has notifications set to allow. I double-check blocked application notifications under “advanced,” and notifications for messages are also set to “allowed.” I’m not sure if you can help me solve another riddle, but for the past 3 months or so, every time I have called my partner, the phone call goes to voicemail the first time, even when he’s not on the phone, and then the second time goes through. This is causing me to lose my mind! No one else mentioned to him that this happen when they call him. I live in Kansas and he lives in Iowa. He has an iPhone 6, and I’ve had 3 phones over the past 3 months, all of which this happens with. When I’m in Iowa, the problem usually goes away (but not always). Thanks for your help! — Cydney

Solution: Hi Cydney. To ensure that you’ll get an icon notification for SMS, you have to enable Allow notifications option under Advanced settings of the Messenger app. Here’s how to do that:

  1. Open Settings app.
  2. Tap Notifications.
  3. Move slider to the right for the messaging app you’re using.
  4. Tap ADVANCED button at the top right.
  5. Tap the messaging app you’re using.
  6. Move the slider to the right for Allow notifications option.

If these steps won’t fix the issue, try wiping the cache partition by doing the following:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key to highlight “wipe cache partition.”
  5. Press the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Should the issue remain, you can also try a full factory reset. Here’s how:

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight “wipe data / factory reset.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, “Reboot system now” is highlighted.
  10. Press the Power key to restart the device.

Your second concern regarding initial call attempts going directly to voicemail may be network-related, or something caused by a bug in the software so you want to talk to your carrier about it. If factory reset won’t fix it as well, coordinate with your network’s technical team to solve it.

Problem 7: Galaxy S8 drains battery fast and won’t charge fully

Took pictures in salt water. A little while later the phone started glitching and the battery drained. Let it dry out for a few days and tried charging the phone, but it would not charge past 10%. Replaced the battery but would not charge past 45%. Wiped the cache partition and rebooted, afterwards the phone showed 96%. Now when the phone charges it won’t show past 18%-45% but it’ll last all day. Sometimes when I have the phone plugged in the battery still drains. When that happens it’ll restart and then it shows a charge of somewhere in the 90% range.

Tried wiping the cache partition again but nothing changes. Not sure if i have a defective battery or if it could be anything else. Any info with this issue would help. Thank you. — Eddie

Solution: Hi Eddie. Try recalibrating the battery first and see how it goes from there. If you haven’t tried doing this procedure, here’s how it’s done:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

If nothing will change after a battery calibration, do a factory reset. If that won’t help either, there must be a physical damage to the phone that needs fixing. Send it in for repair or replacement.

Problem 8: Galaxy S8 won’t turn off

My daughter forgot her password after she put her fingerprint in her Galaxy S8 now the phone doesn’t recognize the print & wants the password. I have tried to hard reset this phone but it won’t let me turn it off. Any suggestions on how I can get this problem fixed so this phone isn’t a paperweight????? — Xxkimberlyxx08

Solution: Hi xxkimberlyxx08. The most effective way to restart an unresponsive or frozen S8 is by simulating a “battery pull,”  also known as soft reset. Here’s how:

  1. Press and hold the Power and Volume Down buttons for at least 10 seconds.
  2. Once the phone starts to vibrate, let go of the buttons.

Hopefully your phone will restart normally and you would be able to turn it off afterwards. If that won’t work though, simply wait until the drains the battery.

Problem 9: Can’t turn off camera shutter sound when taking photos in Galaxy S8

Wanted to turn off camera “click.” Have done so by muting system sounds. But…I don’t know what other sounds I’m turning off by doing so. Can you give me a list? I’m having trouble finding out through googling. Thanks. — Mitch

Solution: Hi Mitch. If you are in the United States, you’re out of luck since it’s illegal to take a picture using a digital camera or smartphone without the shutter sounding off. Yes, that’s right. Samsung is obviously abiding by said law but some phones can still take pictures without making a sound by simply pressing Volume Down button on the side of the phone until the phone goes into vibrate mode. If you haven’t tried that yet, go ahead and see for yourself.

If the first workaround won’t work, try using third party camera apps.

If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.


Problem #1: Galaxy S7 keeps saying it detected moisture

Hey there. I got my Samsung Galaxy S7 about a year ago and I’ve been having problems with it regarding that moisture detection. This time is the worst. Won’t charge at all despite doing everything even if it didn’t get wet or exposed to moisture. I tried pressing the volume down key, power and home buttons and it only asks me whether I want to change my OS. And so I pressed OK and 5 hours after nothing changed. What could be the problem? Hope to hear from you. — Denise

Solution: Hi Denise. Part of protection layer against moisture or water damage is the specially built lower part of your phone, particularly in the charging port area. The charging port is designed to resist water or moisture from leaking inside. In some cases, moisture can remain hidden even after a user has cleaned and dried the phone. If the system detects such moisture, it won’t allow data transfer or charging via USB cable. If your phone has been saying that it’s detected moisture and won’t charge, it probably does. Otherwise, the charging port may be malfunctioning.

Keep in  mind that even just a tiny droplet of water or liquid can trip the built-in moisture detection system so you want to make sure that your phone’s charging port is thoroughly dried. Try using a hair dryer to blow hot air in the port and see if that will make a difference. Be sure not to apply too much heat that might damage the phone though. If this drying method won’t fix the issue, there may be a charging port problem so you must contact Samsung and have the phone repaired or replaced.

Problem #2: Galaxy S7 edge off eBay won’t turn on, screen remains black

Bought my first phone today, off EBay. S7 Edge. Showed battery at 72% but icons page wouldn’t come on or home page. Charged to 100%. Turned off. Now can’t even get the battery icon page to show. Has no SIM card but that doesn’t matter. I think the last user may have downloaded Nougat or something, had problems, just put it on EBay but that’s a guess. Maybe they wiped hard drive clean, who knows? Don’t understand why the battery or charging page would work the 5-10 times I checked and won’t open up now though…just a black screen phone. Try to return this or think you can walk me through repair? $380.00’s not bad. No cracks in screen or anything, looks mint. You’re asking what version it has, I have no way to know since I can’t turn it on. No carrier as that I have no sim card yet. — Eddie

Solution: Hi Eddie. The only thing that you can do here is to try to restart the phone to alternate boot modes so you can do follow up troubleshooting. If the phone remains unresponsive or won’t turn on at all, save yourself a few hundred dollars and get a refund.

For reference, here are the ways on how to boot your phone to alternate modes:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem #3: Galaxy S7 can’t save files to a 64GB SD card

Hello. A few months back I bought a 64 GB card for it because well let’s face I have a lot of media on the device and needed the extra storage. In the beginning the phone wasn’t reading the card and it was a nightmare but i was able to correct that issue. My current issue is the following… I moved (not copied, which i should of), a lot of the media that was on my phone storage to the card and now when i go to those files, the display is a light gray screenshot with an exclamation point in the middle. I know that’s because the file isn’t being read properly. The specs for the media file shows everything, file type, size, name, etc. Also, these files weren’t moved to new folders, but existing folders that already had media saved on it. I can still see the media that was already on the card but not the new stuff i transferred onto it yesterday which is very frustrating. I tried to connect the card to my computer and the computer can’t read the new files either. What can I do to save these files? I already tried the “unmount”, “mount” option and that didn’t work and I didn’t lose any files in that process either which was a good thing I guess. Please assist. Thanks in advance. — Ana

Solution: Hi Ana. Troubleshooting an issue like this does not require advanced steps and only requires common sense ones. Firstly, we want to make it clear that there’s nothing more that you can do if files have become corrupted after you transferred them. Those files that show exclamation marks on them may still retain the metadata or the file specs as you call them but they have already lost critical bits and pieces to read each one as a whole file. If you chose “move” instead of “copy” during the transfer, you may have lost those files for good.

Secondly, the main cause of the problem may lie on the SD card so you want to check if that’s the case. Get a new, known working SD card and format it using your S7. After that, try to replicate the problem by moving or copying files to it. Do the same step several times. If data transfer is successful all the time, that means there’s no issue with the phone and the problem must be on your first SD card. To fix it, simply replace the card and save yourself the hassle. Sure you can try to reformat it but there’s no guarantee that the issue won’t return after that. If you don’t want to invest in a new SD card at this time, consider reformatting the one you have on your phone but be sure not to use it as your main backup storage. Bear in mind that even the most expensive SD card or any digital storage device can fail anytime. If you’ll lose irreplaceable files in the future because you did not create a backup, you only have yourself to blame.

Problem #4: Galaxy S7 not saving pictures to Gallery, charges very slowly

My Samsung S7 screen keys are locked while I am not using a password, the device:

 

  • does not save pictures to the Gallery (gallery file always empty) “saved to device!, where, I do not know ???!!
  • the incoming messages to WhatsApp stop to be received with a notification alarm sound
  • Sometimes the battery charging consume very long time, comes to 10 hours!

 

Is it possible that a virus strike my device? Or a Hacker may be behind? I realized that all of these troubles take place after I downloaded a Power Saving Program named “Turbo power saving ” – already I deleted but problems still remaining. Please advise.  — Mariner1015

Solution: Hi Mariner1015. Like you, we can’t tell if this issue is due to a virus or malware. We don’t have enough details about your phone’s history and information about things running on it right now.

To try to fix the issue, you must do a factory reset and see what happens afterwards. By doing a factory reset, you are restoring all software and app settings to their defaults so any changes you or the malware may have done to core files should be corrected. Here’s how to factory reset your S7:

  1. Create a backup of your important files such as photos, videos, etc.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Problem #5: Can’t set notifications for Galaxy S7 Hotmail email

Hi. My husband and I are not very “techy” when it comes to phones. He has recently purchased a S7 Edge and we thought we had done everything right setting it all up. His main email address is @hotmail.co.uk which he is using through Gmail. We are trying to put a specific notification on it for when he receives email but this seems impossible. We appear only to be able to do this with the Gmail account he had to set up. Is there any way we can do this or is it just that Hotmail and Gmail don’t “talk” to each other ? Thank you for your help. — Kim

Solution: Hi Kim. We don’t think we understand your question fully so kindly get back to us if you think our interpretation is incorrect.

As far as setting notifications in Android Marshmallow and Nougat is concerned, everything is outlined clearly in Settings>Notifications. As far as email notifications under Gmail app is concerned, your only option is to either turn it on or off under the app’s own settings menu.

Problem #6: Galaxy S7 Gallery app acting up when deleting a photo

Hi. Recently I’ve been having this problem which I noticed today. When I go into my gallery and delete a picture or two, when I swipe to the next picture, my screen suddenly twitches out and goes back to the picture. By twitching I mean the screen moves side to side and moves on to the next picture. I was wondering what might have caused it because I once pressed down on my screen which made my screen touch the amoled panel. I wasn’t sure if that was the reason. Please reply and help, thank you. — Imran

Solution: Hi Imran. There may be an app bug causing the problem. To fix it, make sure to clear the cache and data of the Gallery app. Before you proceed with this step, make sure that you create a backup of your photos and videos.

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

If nothing changes after clearing the cache and data, do a factory reset. Steps are provided above.

Problem #7: Galaxy S7 splitting long SMS

Hey. So I was reading your article on how to fix the problem of receiving texts and them being split up if they are too long. Well, sadly, your guide appears to be outdated now. You say to go to apps, messages, more settings, texts, and then enable an option that combines the texts. This option is no longer available or my phone simply does not have it there (unlocked carrier US Galaxy S7 Edge running the latest update). — Greenfox1012

Solution: Hi Greenfox1012. Android in general and carrier-provided firmware in particular constantly evolves so some settings may change, removed, or placed somewhere else. Due to logistical challenges, we can’t regularly keep track of our solutions so we can modify them so we apologize for any inconvenience the post you read may have caused you. We encourage you though to get back to us by giving us a more detailed problem description and we will do our best to help you.

Problem #8: Galaxy S7 edge “No subject” error when receiving SMS, cannot send and receive MMS

I use to own an iPhone 5s and now I switched to a S7 edge, and I am experiencing a messaging problem on my phone. I have been constantly getting “No Subject” errors whenever I get a message, and I also can’t send or receive photos. I got the S7 edge for my birthday from my uncle who doesn’t use it anymore. My number is not registered with iMessage by the way. Please Help. — Jonathan

Solution: Hi Jonathan. This may be a messaging app problem so the first troubleshooting step that you want to do is to clear its cache and data, just like what we suggest for Imran above.

If that won’t fix the problem, you can also try to wipe the cache partition. Here’s how:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

If both of these procedures won’t solve the issue at all, contact your carrier and ask them for direct assistance. The error may be  caused by a firmware bug, which means it involves changing the code of the operating system.

You also need their assistance in ensuring that your phone is properly configured to send and receive MMS.

What to do with your Samsung Galaxy S9 that won’t charge and shows ‘moisture detected’ error (easy steps)

When your Samsung Galaxy S9 tells you that it has detected moisture in the charger port, you should believe it because it’s probably true. The feature to detect moisture in the port comes with IP68 rating. The first devices with IP67 rating didn’t have a moisture detection capability as good as that of S8 and the new S9. That’s the reason why you must do something immediately after having an error like this.

The ‘moisture detected’ error shows even if there’s just a small drop of liquid in the port and the charging process is halted to prevent further damage. In this post, I will share with you things that you can do to get rid of the error and even bypass it if you badly need to charge your phone. But bear in mind that if you neglect it, your device might suffer from liquid damage which may also result to some very complicated issues.

Before going further, if you found this post because you were trying to find a solution to your problem, then try to visit our Galaxy S9 troubleshooting page as we’ve already addressed most of the commonly reported issues with the phone. We’ve already provided solutions to some of the problems reported by our readers so try to find issues that are similar with yours and use the solutions we suggested. If they don’t work for you and if you need further assistance, fill up our Android issues questionnaire and hit submit.

What to do if Galaxy S9 shows ‘moisture detected’ error

First of all, the ‘moisture detected’ message is actually not a problem but simply a notification. It offers a solution than cause a problem unless it pops up even if the phone is totally dry like what happened to some of the S8 units last year. With such possibility, we need to determine if there really is a valid reason why the error shows in the first place. With that being, here’s what I suggest you do about it…

Reboot your phone first

The error is handled by a service that also has a tendency to crash from time to time. When it happens, the error may pop up even if the phone’s charger port is totally dry. To address it, you just need to reboot your phone normally because that often fixes minor glitches in the system or hardware.

So, hit that power key and restart your phone. After that and the error is still showing up, try doing the Forced Restart by pressing and holding the volume down and power keys at the samet time for 10 seconds or until the phone restarts. This simulates battery disconnect which refreshes your phone’s memory, closes all apps running in the background and reloads all functions and services.

If the error is still showing up whenever you connect the phone to its charger, then try doing the next step.

RELEVANT POSTS:

Clean the charger port

As the owner, you should know if there’s a reason for your phone to pop the ‘moisture detected’ error up. For instance, if you took a phone underwater or if the phone got splashed with water and then this issue started, then it’s more likely that there’s moisture in the port. To address that, you simply have to clean the area.

You may use a cotton swab or a small piece of tissue paper that you have to insert into the port so that the moisture will be absorbed. Just make sure that you don’t damage the pins. You may also just let the phone sit on the table upright and leave it for a couple of hours for the port to dry out. If you want to do this, then turn the phone off.

Aside from cleaning the port, you should also check the cable that you use to connect your phone to its charger. If it’s wet or has moisture, the same thing will happen. You just shake the cable a few times to get rid of the moist or you may give it a blast of compressed air.

However, if you’re pretty sure that the phone didn’t get in contact with water and if the error started showing up after an update, it’s possible that the problem is with the caches and/or system files. In this case, you need to do the next procedure.

Backup your data and reset your phone

That’s right! A reset will be able to fix this issue provided it’s caused by a firmware problem. So, make a backup of your important files and data, disable the factory reset protection and then follow these steps to reset your Galaxy S9. If you’re wondering how to disable the factory reset protection, you simply have to remove your google account from your phone. You do this so that you won’t be locked out after the reset.

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

How to charge your Galaxy S9 even with ‘moisture detected’ error

You can actually bypass the error and make your phone charge normally. You may need to charge your phone before a reset to make sure the process isn’t interrupted or if you need to backup your files and there’s not enough battery to do so. Here are the things you can do to make your device charge…

  • Turn your phone off and then connect it to its charger. Remember that for the error show up, the phone should be powered on.
  • Use a wireless charger. The notification shows if the phone detects moisture in the charger port. When charging wirelessly, the charger port is not used so the error won’t show up.
  • Charge the phone in safe mode. In case you’re waiting for a message from someone and you badly need to charge your phone while it’s powered on, you can do so while in safe mode.

This is how you run your device in safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the screen.
  3. When SAMSUNG appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

Galaxy S7 restarts by itself when wifi is used, can’t set up email accounts after an update, other issues

Welcome to another #GalaxyS7 post. We typically don’t publish more than 10 topics per post but since we’re been getting more and more reports of S7 issues lately, we bring you 12 issues in this one today. We hope this becomes another helpful reference for our Android community.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 edge stuck in loading screen after an update

I have a Galaxy S7 edge and the Nougat update was pestering me for about 2 weeks to install and I couldn’t delete it from my task bar. So I finally started it and my phone has been stuck restarting since. It will restart until the battery runs out and then I can recharge it and it will freeze in the restart process again and I can do nothing till the battery is dead again. I’ve tried to start it in safe mode or even to do a hard rebooting but it won’t respond to the buttons. — Colin

Solution: Hi Colin. We don’t think you’ve provided us with enough relevant information to help us identify the cause why your device freezes and fails to boot normally so the only suggestion we have for you is to try restarting it to Odin or Download mode first. If you can do that, there’s a chance that you may be able to manually install (flash) the previous firmware version, or the most recent one, Android Nougat. If your device remains stuck and won’t respond to any hardware button combination at all, you have no other choice but to send it in.

For reference, here are the steps to get your phone going:

How to soft reset (simulated “battery pull”) a Galaxy S7

  1. Press and hold the Power and Volume Down buttons until the Maintenance Boot Mode screen appears (approx. 10 seconds).
  2. From the Maintenance Boot Mode screen, select Power down. You can use the Volume buttons to select items.

How to boot a Galaxy S7 to Download/Odin mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to flash a firmware to your device.

Problem 2: Galaxy S7 restarts by itself when wifi is used, won’t receive cellular signal until it restarts

Hi. I’m facing a problem. Whenever i connect to wifi in a public place like hotel or mall my phone would start to restart by itself and it won’t stop. I can’t use my keyboard and i can’t switch the wifi off. That’s even before i log in to connect to the internet.

Another problem is when I’m in no service area and i go to place where should be service my signal doesn’t work till i restart my phone or put it flight mode and back. Thanks. –Dom

Solution: Hi Dom. It looks like your phone can use a factory reset at this time. Both issues you mention appear to be caused by an operating system glitch. Overhauling the software environment with a factory reset may be the only effective solution. If you haven’t tried to do it before, here are the steps:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

It’s important that you check how your phone’s wireless capabilities work right after a factory reset. Be sure to let the phone run for an hour without any apps installed so you’ll see the difference. If wifi and cellular network function work fine when there are no apps installed, you can then proceed to re-install your apps. If the problem returns once apps are installed, there’s a chance that one of your apps is to blame instead of Android itself. Make sure to uninstall apps one by one until you’ve identified the problematic app.

Problem 3: Galaxy S7 won’t turn on, keeps showing moisture detected error

Got the moisture detected error even though it showed no signs of getting wet. There was no moisture or water detected anywhere in the lifeproof case–and there was nothing around wet. Phone worked fine, even charged on and off with error. Every so often screen would go black and switch to VR setup (which I have never opened before) or the camera. Phone completely died and then would not respond at all on regular charger. Put it on the wireless charger which indicates phone is charging but the phone is unresponsive (like no activity, no lights). Tried all reset and reboot options, phone is acting as if it is dead. I’ve also tried everything as if it was water damaged (rice, trip, etc). I have no idea what operating system I am on, whatever it comes with. — Jenniferpoolehinson

Solution: Hi Jenniferpoolehinson. If your phone won’t turn on at all, the only troubleshooting that you can try is to see if you can power it back on to other modes. If it stays dead, have it checked by a professional. There may be an issue with the battery or motherboard.

Below are the steps to boot a phone to alternate modes:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem 4: Galaxy S7 edge bottom screen shows as white while upper half shows as black

I woke up today and when I tried to turn on my Samsung Galaxy S7 Edge, half of the screen was white and the other half was black. Every time I press the home or power buttons it displays the half white screen and immediately turns off. However, when I double press the home button it displays half of the camera and the other half remains white. I tried pressing the power and volume buttons but it didn’t change a thing. — Tony

Solution: Hi Tony. We think you have a damaged screen. This issue does not happen out of the blue so if there were no obvious reasons why it works erratically such as physical damage or water damage before noticing it, there may be an underlying motherboard failure.

To check if this is due to a software problem (we doubt it though), try to boot the phone to Recovery or Download mode (steps provided above) and see if the screen works normally. If it doesn’t, find a way to have it repaired or replaced.

Problem 5: Galaxy S7 edge SMS keeps getting delayed

Hello. I have been having text messaging issues with my Samsung S7 edge I just purchased. At times I can send and receive messages but most of the time I cannot or they are delayed for hours or days. I have tried everything from restarting, factory reset, changing SIM cards, clearing cache partition, factory reset and even exchanged the entire phone for a new boxed one from my carrier T-Mobile. What gives? I noticed that these messaging issues began with a recent Firmware update that for some reason I cannot avoid with each factory reset/new phone. What should I do a thing this point? Should I just get an entirely new model even though my carrier says that it’s not possible without paying a huge fine? This is so frustrating : /. — Ncduckie

Solution: Hi Ncduckie. If a factory reset did not fix the problem, it’s most likely caused by a network issue or inefficient coding in the firmware. You must work with your carrier to identify the cause. If you’ve done that (simply because the customer service guys on the other end don’t have any clue), you may have to just wait for a new update. Hopefully, a new update will fix the glitch.

In some rare cases, using a non-Samsung or non-carrier provided messaging app fixed a similar issue. Try using another app like Facebook’s Messenger or Google’s Hangouts and see if that will help.

Problem 6: Galaxy S7 camera and flashlight app won’t work

Camera says warning camera failed. And when I try to use the flashlight it says .. unable to turn on Camera is using the light. I have tried all the fixes…. restart, cleared caches, etc. to include a hard reset. Still nothing. When I go to my menu the flashlight icon is lit up … but it is not on on my phone. — Cgconstruction1994

Solution: Hi Cgconstruction1994. We are assuming that you’re having problems with pre-installed camera and flashlight app so your first move is to check if a third party app is causing this problem. Boot the phone to safe mode and see how the camera and flashlight apps work. If they work just fine when on safe mode, that’s a confirmation of our hunch. To boot to safe mode, follow these steps:

  1. Press and hold the Power button.
  2. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  3. Continue holding the button until the phone finishes rebooting.
  4. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

If you happen to use third party camera app and flashlight app, do another round of factory reset and install them first. Make sure not to install anything else. Then, see how of them work.

Problem 7: Galaxy S7 active sound notifications not working

On my Samsung Galaxy S7 active, all of my notification sounds work except for text messages. I’ve made sure my notification sound is all the way up, notifications are allowed on my messages app (the default for the phone), the “show silently” option isn’t checked, and the messages aren’t muted for any of my contacts. I’ve restarted the phone a million times and I even tried switching notification tones. Is there anything left to try other than a factory reset? — Erynn

Solution: Hi Erynn. Try booting to safe mode to disable third party apps. Once that’s done, send an SMS to yourself and see if sound notification works. If that won’t change anything, do a factory reset.

Problem 8: Galaxy S7 email app disappeared after restart, can’t install update

Hi Guys. Galaxy S7 three months old. Had a few ‘shut-downs’ fixed with the soft reset but during latest “freeze” the unit became very hot to touch. Soft re-set after it cooled down, worked ok but then noticed it had completely removed all my emails and the email settings and program itself. Any way I can get my e-mail back?

Additional issue is repeated software update attempts which fail but I’m told by Samsung this is because I have a UK model being used in Australia. — James

Solution: Hi James. We don’t know what you mean exactly by “it had completely removed all my emails and the email settings and program itself” but if the app itself was uninstalled for some reason, simply re-install it and configure your email account to it again. If you happen to have an issue with a pre-installed email app, do a factory reset (steps provided above).

If your phone was built for a particular carrier in the UK and you’re now using it in an Australian network, you can’t expect to receive over-the-air update for it. If you badly wanted to update your phone, you can do it manually via flashing. You can use Google to find a good guide on how to flash the latest firmware.

Problem 9: Facebook and Snapchat apps don’t have sound notifications on Galaxy S7

I do not get notification SOUNDS from Facebook or Snapchat. I have checked all settings, uninstalled and reinstalled several times. I Googled this issue. A post said to try an older version of FB. I did that and sounds worked for a couple hours then stopped!! One thing I did notice I have to go to account settings and click on sync each time I reinstalled the older version app and it will not sync at all with the newest version of Facebook !! Thank you for any help !! — Tami

Solution: Hi Tami. Please check our suggestion for Erynn above. We assume of course that you know how to change the notification settings for an app under Settings>Notifications.

We don’t know where you get “older” Facebook app versions since you can’t do that in Google Play Store so you should also ensure that your apps are not compromised. Some official copies apps can be booby trapped by third party developers. If you’re fond of getting apps from third party sources outside of Google Play Store, you should be aware that some of those apps may not be safe or can present problems. You should work with the developer of those unofficial apps for solutions.

Problem 10: Galaxy S7 sends duplicate or delayed messages at random

It appears that in using the Message+ app, my phone is sending duplicate texts and the recipient is receiving messages already received hours or even days apart. They are not sending two messages at the same time and it isn’t that the recipient never received the message. They will receive the message when I send it and then will randomly receive the same message days later in a completely unrelated conversation. — Katestefan07

Solution: Hi Katestefan07. Message+ is not a Samsung app so if the usual troubleshooting of wiping its cache and data (steps provided below) and factory reset did not work, there may be an app or network issue behind it. You must do one or all of the following to fix the problem:

  1. switch to a different messaging app,
  2. contact the app developer and ask for assistance, or
  3. work with your carrier to fix a possible network issue.

To wipe an app’s cache and data, follow these steps:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

Problem 11: Galaxy S7 keeps getting “Settings has stopped” error

Hi. I have done all the troubleshooting steps you mentioned to fix the “settings has stopped” issue and the lagging. The one fix that worked was to clear the settings data and cache, however, it will only works once and then give me the same error message. Then once i clear it again it works once etc etc etc. I have no idea what else to try and am hoping like hell you can help. I have a Galaxy S7 edge with android version 7.0. I just did the update 3 days ago. Thanks for any help you can provide and look forward to your reply. — Vito

Solution: Hi Vito. If wiping the app’s cache and data did not work, try wiping the cache partition next. If that won’t work either, factory reset the device.

Below are the steps on how to wipe the cache partition:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Problem 12: Can’t set up email accounts on Galaxy S7 after an update

I purchased a Galaxy S7 a couple of days ago. I set up 3 email accounts, one of which is a work specific one (NHS mail) the other a Gmail and btinternet account. all was straightforward and without problem and functioning correctly. There was a software upgrade to Nougat 7.0, and since this happened I can only access the NHS mail account as I get the message: Unable to set up account: Security policy restricts the use of POP/IMAP email when trying to use the others. I have removed both accounts and tried again to no avail. I have rebooted the phone and tried again, still no luck. Any ideas?? Kind regards. — Sally

Solution: Hi Sally. In Gmail, there’s an option for a user to enable or disable POP and IMAP under Settings. You can access it logging into your Gmail account in your computer and clicking on the gear icon. The POP and IMAP options should be under Forwarding and POP/IMAP section. Make sure that both POP and IMAP are enabled before setting up your Gmail account in your email app again.

We’re not familiar with btinternet email so you have to figure a similar option yourself. Better still, contact the email provider and ask for assistance.

Problem 1: Galaxy S7 edge won’t turn on normally, stuck in Download mode

Hello. I have a Samsung Galaxy S7 Edge. Last night I left my phone to charge with my Samsung fast charging adapter while my phone was 2%. It was plugged in for about 10 hours before i came to check on it in the morning. The LED light would not respond, none of the keys will respond to the phone and it just shows a black screen. Now what happens next is something that I have never seen before. 10 minutes after trying to solve the problem, a sky blue screen pops up with saying “press the up volume key to install and press the down volume key to cancel(restart)”. After seeing this I was hesitant to download it so I continued to press down and cancel. After not seeing any other possible solution I did press up and download it. I don’t remember what it said, but it was unfamiliar. I tried the many troubleshoot solutions like factory resetting or deleting cache but the phone will not respond in any way shape or form. — Antonio

Solution: Hi Antonio. Try to see if you can boot the phone to Maintenance mode. If it does respond and boots successfully, you may be able to restart the phone eventually back to normal mode. Below are the steps that you should try:

  1. Turn off your Galaxy S7.
  2. When powered down, press and hold the Power and Volume Down buttons at the same time.
  3. Continue holding these two buttons until you see the special Maintenance Boot Mode Menu.
  4. Let go of both the Power and Volume Down buttons.

If your phone remains unresponsive and only turns back on the current Download mode screen, you must then try to flash the bootloader back to stock. If that won’t work either, have the phone repaired or replaced.

For reference, here are the sample steps on how to flash a bootloader. Exact steps may be slightly different on your phone so make sure to look for a good guide online.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Problem 2: Galaxy S7 screen stays black, won’t show anything

Soft reboot works. It charges fully. I’m getting sounds and the digitizer works and haptic feedback. But i cannot get the screen to display anything. I can’t pull the battery because it’s an s7 and sealed and my glass would break if i pulled it apart. I’m pretty sure it’s the LCD that has failed but they are expensive. I’ve very tech savvy and have flashed Rom’s on other phones. Is there a way to get error codes or duplicate the screen on a computer to see what errors might come you. Any other solutions or help would be appreciated. Thanks. — Tyson

Solution: Hi Tyson. There’s no magic software solution to fix a bad screen. If the devices appears to receive notifications and shows indications that it’s turning on at this time, you have no other option but to send it in for repair. You can’t just plug it in and expect to be able to access the memory and do some software tricks to fix a malfunctioning screen assembly. If it’s under warranty, send it to Samsung and let them handle the screen replacement. Otherwise, let an independent technician replace the bad component for you.

Problem 3: Galaxy S7 won’t turn on after charging port got wet, keeps showing moisture detected error

Hi. My name is Kelsey. I have a Samsung Galaxy S7. I was in my pool taking pictures under water. When I do this i never put my ports under water. I always make sure to just put my camera under the water while holding my phone upside down. As risky as this is, i normally never have a problem. Well today my little cousin decided to blow water on me from his mouth and it got into my port. Not thinking anything of it, being the phone as water resistant, I just set my phone down. When I got to my charger later I plugged it up and it gave me the “moisture in port” message. I then took an air dryer to try and dry it off. ( I now know this is a really stupid idea). I then tried plugging it up and it gave me the “downloading do not turn target off.”Then i believe it went completely dead again because that screen turned off. When i plugged it up for what felt like the millionth time it came up with the battery with the lightning strike in the middle. But when it was actually charging in the past, I had little green bubble like things blinking up to the display battery ( I hope this makes sense) .They are not popping up now. It is simply just the battery with the lightning strike. Does this mean I need to start looking for another phone? please tell me no. Thank you in advance! Sincerely. — Kelsey

Solution: Hi Kelsey. Using an air dryer is not really a bad idea in this case as long as you take care not to apply too much heat to the phone. A Galaxy S7 is water resistant and it’s supposed to alert its users not to charge if there’s traces of moisture in the charging port. As long as the system detects moisture in that part, the phone will not charge at all. This may be the reason why you are no longer able to turn it back on. The battery may have simply run out of juice at this time. Make sure to dry the charging port by gently shaking the device. If the phone will never charge after you’re certain that the charging port is now moisture-free, contact Samsung for a repair or replacement.

Problem 4: Galaxy S7 won’t connect to wifi, Home button not working properly

Hi! I have a Galaxy S7 and have had no issues until recently. Within the past week, I have had 3 issues:

  1. trouble connecting to my Wi-Fi. I was able to solve this by turning on/off airplane mode several times.
  2. pressing the home button creates a screenshot – this is still occurring and restarting the phone does not solve this. This happens intermittently
  3. I keep getting a message out of nowhere to hold down the power button for several seconds to restart the phone.

I have not updated or installed any new apps. The phone says there is no update needed. I just find it odd that I have had 3 major issues in the past several days after not having any problems in the last two years. Thanks for any help you can give. — Alison

Solution: Hi Alison. If these issues appear out of nowhere, something drastic must have happened to the software or hardware. If your phone was exposed to water or elements, or was physically impacted after an accidental drop, bad hardware may be to blame. In this case, you would want to stop looking for a solution and simply have the phone checked. Only after a thorough physical check can a technician tell if repair will be able to fix the problems or not.

If your phone was never dropped or got wet before, do a factory reset and see what happens from there. If this is a software-related problem, your issues should not occur right after a factory reset (when there are no third party apps installed).

If the phone works normally after a factory reset but starts to act erratically after installing back your apps, one of them must be to blame. You must identify the problematic app using elimination process.

To factory reset your phone, follow these steps:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Problem 5: Galaxy S7 can’t transmit sound in calls or text

Hello. I have an unlocked Samsung Galaxy S7 which I received from my brother and I am on the Freedom mobile network in Ontario Canada. A year or so ago when I received this phone I was quick to discover that it is not compatible with the wind mobile (now freedom) frequencies. I had to spend 30ish Canadian to have a man at a booth install a fix for this as nothing I tried worked (installing modem files etc). It worked fine for a while until one day my phone stopped allowing me to hear and transmit sound in phone calls or even messages. I have tested the microphone using Facebook messenger and voice recorder and it works just fine! I want to know if there’s a way for me to fix this frequency problem on my own as I should not have to spend 30 dollars to fix this again when neither my phone maker or service provider will help me in the slightest. — Kristian

Solution: Hi Kristian. We don’t know what you mean exactly by the “frequency problem” you’re referring here but we assume the person who fixed your device tweaked the software. Technically, if we say a device is not compatible with a network’s frequency, that’s because a phone’s radio can only work with limited frequency bands. You can’t just change the operating frequency bands of a device to make it compatible with the frequencies of a certain network.

As much as we would like to help you, there’s nothing much that we can do about your issue. You must let a technician physically check the device so he or she can determine what software changes needs to be done.

Problem 6: Galaxy S7 slow when opening text, videos won’t play, keyboard not working properly

I have a Samsung Galaxy S7 and have never had issues until this last month. It is very slow to respond when opening messages from text or messenger. Videos won’t play through and keep pausing and I have to keep pressing play again. Sometimes keyboard stays on screen longer than messages screen so have half keyboard/ half home screen showing. I currently run 360 security app on my phone but have been told I don’t need this or any antivirus, is this true? Help please. — Jessedwards

Solution: Hi Jessedwards. Instead of fixing issues individually, we suggest that you do a factory reset instead to try and fix all of them. To see if a problematic app is to blame, you also want to make sure that you don’t re-install apps right away after a factory reset. This will allow you to check if there’s a difference when the phone only runs a clean version of Android and when there are apps installed. To factory reset your S7, follow these steps:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Problem 7: Galaxy S7 stuck in endless boot loop

The phone is stuck in an endless loop of restarting and then getting stuck on the Samsung logo. I have tried everything on your blog related to this but this isn’t going away. If I press the volume down key after the Samsung logo appears out just restarts.. Doesn’t move into the android logo but gets stuck again. Can you please help? — Tejraj P

Solution: Hi Tejraj P. Please see our suggestion for Antonio above. If the phone won’t respond or remains stuck in boot loop, there must be a hardware problem causing it. In that case, have the phone repaired and replaced.

Problem 8: Galaxy S5 and S7 incoming calls are being diverted to voicemail

My partner has a Samsung Galaxy S5 and I have a brand new S7. We both have the same problem. We are with Plusnet and when we are set to connect automatically to 2G/3G & 4G our phones will not receive phone calls but go straight to voicemail. — Lorraine.braddon

Solution: Hi Lorraine.braddon. This is an issue that only your carrier can fix so we suggest that you let them know of this issue as soon as possible. There must be some misconfiguration in the device or in your account that forces incoming calls to your voicemail.

In some cases, users may forget that they may have enabled call divert feature on their number. Be sure to talk to your carrier technical support team about it so they can walk you through how to check it.

Problem 9: Galaxy S7 speaker volume is low during calls

I bought a phone on eBay. Finally got it to connect to our wifi and it seems to work OK but I can barely hear the caller when I receive calls. I’ve tried increasing volume but that just makes the ringtone etc louder. I’m not super technical. My brother says “aol” stands for all old ladies… Can this be fixed? I’d appreciate any help. Thanks. — Ashley

Solution: Hi Ashley. If the volume problem only occurs during calls but not in other functions that require the loudspeaker such as when playing music or videos, then the reason must be on the software side. Try to use a different app for calls like Facebook Messenger or Google Hangouts. There are a ton of other similar apps in Google Play Store so take your time in testing them out. If the problem persist after using multiple apps, consider doing a factory reset. Refer to the steps above on how to do it.

On the other hand, if said problem happens whether you’re in a call or not, it’s probably due to a faulty hardware, particularly a malfunctioning loudspeaker. As a workaround, you can try using a wired or wireless headset during calls. If you don’t want that, have the phone replaced.

Problem 10: Galaxy S7 screen flickers when brightness is set to low

Hello! I have a Samsung Galaxy S7 and lately whenever i turn the phone brightness lower than halfway up the bottom 1/3 of the screen flickers. The flickering persists in any app and I’ve tried soft resetting. what might this be? — Matt p.

Solution: Hi Matt p. An issue like this is usually caused by bad hardware. Try a factory reset and see what happens after that. If the problem stays, get a phone replacement.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 keeps overheating, works fine when in safe mode

The battery gets hot and phone resets. I rebooted in safe mode and it stopped resetting. I deleted most recent apps, but it would still reset. The only time it did not reset was when the phone was in safe mode…or when in normal mode with airplane mode. I am outside of the USA. Anytime I turn on the wifi to get an internet connection, the phone battery will get hot and within a couple minutes it resets. — Justin

Solution: Hi Justin. One of the results of an overheating phone is untimely reset. That’s a built-in mechanism to prevent heat from damaging the motherboard. If your phone won’t overheat in safe mode for an extended period (we assume you’ve already tried it before contacting us), that’s a clear indicator that a third party app or service is hogging resources causing the system to eventually overwhelm itself. Apparently removing recent apps is not enough. You should continue to eliminate possible problematic apps until the overheating issue stops. Once the phone stops overheating, that’s the sign that the buggy app has been removed from the system.

Problem 2: Galaxy S7 not receiving app notifications after an update

Hi. Since I did an update on my S7 a couple of months ago, I’ve stopped receiving notifications from apps. I do get text messages, missed calls. However, I’ve stopped receiving WhatsApp, Snapchat, Twitter and emails. Last year when I did the update, I stopped seeing contact names when they called. This recent update corrected that. But, has stopped my notifications. If I go into the apps, I can see my messages. But, it never comes through. My Gmail might come through, but only if I open the app, with for a few seconds then exit. This doesn’t work for Outlook or Snapchat though. Thank you for your time and assistance. Kind Regards. — Anandraadams

Solution: Hi Anandraadams. The first thing that you want to do is to wipe the cache partition. This will clear the current cache and replace it with a new one. Sometimes, updates and app installation can corrupt this type of cache so it’s good if you can deal with it first. Here are the steps to do that:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Sometimes, installing app updates can also fix post-Android update issues. Make sure that you only install updated and compatible apps.

If that won’t help either, do a factory reset. Refer to the steps below.

By default, apps should make sound notifications after a factory reset. Make sure to go under Settings>Notifications to check if sound notifications for your important apps are set properly.

Problem 3: Galaxy S7 edge screen remains black, won’t turn on

I have a Galaxy S7 Edge with some issues. Currently my phone has the black screen of death so I can’t see the screen display. I’ve tried to hard reset the phone and when I do the screen is still black, but the blue light that usually lights up is there. I’ve tried to turn the phone off to try to manually factory reset it but I can’t turn it off. So I think that the touch screen is unresponsive.

When I press the power button as if I were to wake the phone the LED touch buttons at the bottom light up, but a brief green flash appears on the screen and disappears. I also had issues with my display before the black screen of death. Before this issue, I had to keep the screen on auto brightness turned up to 100% otherwise there would be green with a double vision like purple display. The lower the brightness the worse it got. So I tried to restart the phone, which ended up in the black screen of death and my unresponsive touch screen. I have no idea what to do. — Dakota

Solution: Hi Dakota. There’s nothing much that you can do about this issue. If the screen remains dead even if you try to boot the device to alternate modes, that means that the screen assembly is broken. You need to have the device checked so it the hardware can be assessed. The most likely outcome is a screen replacement. If your phone is within the warranty period, make sure to take advantage of whatever freebie you can avail.

Problem 4: Galaxy S7 keeps getting a blank blue screen and moisture detected error

My S7 edge was getting a blue screen blank and it is less than 3 months since I bought it. I had to drain the battery and completely recharge it to get it to work. It is continuing to do this at random. It seems like a software glitch. It’s like the screen of death!! Keeps saying there is moisture in the USB port and then won’t charge but took to the phone store and no moisture in the phone on the indicator. But they won’t do anything either. Honestly I can’t tell you the version because it is dead again Frustrated!!! — Geoffrey

Solution: Hi Geoffrey. Your Galaxy S7 has water resistance protection and part of that protection is the moisture detected warning you’ll get when the system detects moisture in the charging port area. As long as the device is reading that there’s moisture in that part, it will never charge by cable. If your phone was never near water recently and you’re 100% positive that there’s no moisture in the charging port, then it’s possible that the system is getting incorrect readings from the charging port. Keep in mind that smart as your phone is, it’s not that smart enough to actually check if the reading it receives from the charging port is true or not.

The erratic moisture detected error and the random screen of death issue may be signs of some deeper hardware problem so if a factory reset won’t fix them, send the phone in.

Below are the steps on how to factory reset your device:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Problem 5: Galaxy S7 edge keeps overheating, keyboard not working

Good evening. I’ve recently bought a Samsung Galaxy S7 Edge in Germany, and moved in to Brazil. Today, my phone’s keyboard all of a sudden stopped showing up. As I start the phone, everything else in the phone – every app, even the keyboard’s app – still works fine. But then, the phone restarts and get really hot in a specific area of the phone. I’m desperate, I have thousands of pictures which are really important to me there and aren’t synchronized with the cloud. I’ve restarted the phone countless times and wiped the cache out to no effect. I’ve also restarted the phone in Security mode, only to experience the same issue. If you think that a hard reset is necessary, is there any way I could retrieve my data? — Pedro Angst Maciel

Solution: Hi Pedro. You need a working touchscreen to allow an external device like a computer to access files in the phone. The phone also has to stay on long enough to allow the transfer to files to finish. If both are not satisfied, you can’t really create a back up of your files.

Try to bring your phone to your local shop and see if there’s anything that they can do about it, especially regarding the overheating issue.

Problem 6: Galaxy S7 mobile data is spotty, SMS won’t send

Just recently started having issues with my phone in the last couple weeks or so. Data is suddenly very sketchy in places where I never had problems before, like at my office downtown. Try to get on Facebook or something else and just get the “loading circle.” So I turn on the WIFI at the office and internet works fine but then I am unable to send any texts unless I turn the wifi off. If I attempt to send a text with the wifi on, it just says “sending” with the loading circle and it will do this forever, or until I turn off the wifi. I have never had these kinds of issues before and am not sure what is going on.

Also, I used to have full bars at my office, now only a couple. Not sure what is going on. — Jess

Solution: Hi Jess. If basic software troubleshooting like a cache partition wipe and factory reset won’t help, then the problem is either network related, or something with the phone. We suggest that you contact your carrier so they’ll know that you’re getting weak signal in an area with a previously good coverage. You also want to let them to help you with that text sending problem.

If they’ll say that everything’s good on their end, then it’s most probably a phone issue. Make sure that you do a factory reset and install Android updates afterwards. If both procedures won’t work, consider getting a new phone.

Problem 7: Galaxy S7 not receiving SMS using stock messaging app

S7 stopped receiving texts. I’ve done everything short of a factory reset. Which really I don’t have the time for. But the issue is fixed when I download a third-party messaging app. all the sudden my text work and it even sinks them into the stock messaging app. But once I uninstall the third party app Go SMS Pro, all the sudden I get no texts again and the stock messaging app stops working again and I get a message up that says messages has stopped working.

I uninstalled Go SMS Pro just to check and see if maybe my text were working again so want to go pay a bill and at the moment when I’m expecting the text that payment was received instead I receive a message saying messages has stopped working on my Android touch screen. — Vertimusmaximus

Solution: Hi Vertimusmaximus. Make sure that you delete the messaging app’s cache and data first. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

If that won’t fix the issue, restart the phone to safe mode and see if the stock messaging app works. Safe mode blocks third party apps and services so it’s a good way to know if an app is responsible. Below are the steps to boot to safe mode:

  1. Turn your Galaxy S7 off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button

If it still fails to receive SMS, that’s the time that you want to do a factory reset.

Problem 8: Galaxy S7 froze showing a black screen

Hello. I have a problem with my phone. I was having trouble connecting to my internet so I told my phone to restart. Sometime while it was restarting it froze on a black screen while the notification light was blue. tried holding all the power home and volume button combinations I could think of and find with a google search and eventually lead me to your page. Please let me know what I can do. Thank you. — Sheldoncheeks69420

Solution: Hi Sheldoncheeks69420. You should try to do a simulated “battery pull,” also known as soft reset. Here’s how:

  1. Press and hold the Power and Volume Down buttons until the Maintenance Boot Mode screen appears (approx. 10 seconds).
  2. From the Maintenance Boot Mode screen, select Power down. Utilize the volume buttons to cycle through the available options and the Home button (located below the display) to select.

A soft reset should force the phone to restart to normal mode. If that won’t help, do a factory reset via Recovery mode. Check the steps above.

Problem 9: Galaxy S7 stuck in boot loop, screen remains black

While charging I got a Whatsapp message. then I opened and read it, suddenly it goes tinted blue screen. I removed it from the charger and I tried to restart it. when I press and hold power button for around 20 seconds, I got the logo and after 1-2 seconds it disappears. I keep on doing this, but my problem is, I can’t  see anything, but I got message notification sounds. the notification light blinks, I don’t know what is the problem. but I am unable to see the screen, but I am able to boot to recovery. Please let me know the solution. — Srikanth

Solution: Hi Srikanth. Your phone may have become stuck in Samsung logo page, or doing a boot loop. Since we don’t know the full history of the device, there’s nothing much that we can say. However, if this issue started after you installed an update, or after flashing or rooting, you may to do a more drastic solution. That solution is to try and flash the bootloader and/or firmware back to stock. Below are the sample steps on how to flash a bootloader. They are provided here for demonstration purposes only so be sure to do your own research on how to flash a bootloader for your particular phone model.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Problem 10: Galaxy S7 not receiving calls and SMS

So my phone was doing fine for the first 3 weeks until my phone started getting issues. I would be able to text people and call them but not receive texts or calls. Sometimes I would be able to receive some texts but hours later when it was sent. Now, my phone doesn’t receive neither text messages or phone calls. I tried resetting and taking out the SD card, but didn’t work. I checked to see if it had to do anything with an app but it wasn’t that either. Also checked to see if it was on block mode but it wasn’t. If you can help that would mean a lot. Been trying to fix it for a couple of days now with no help. Maybe there’s a setting I new to change. I don’t know. — Alec

Solution: Hi Alec. If your phone was able to receive calls and text before, then it’s either a device configuration issue, or something network-related. Contact your carrier and ask help on how to reconfigure your device (assuming their network is working fine at this time).

Problem 11: Galaxy S7 won’t detect 2 SIM cards

I have been using my phone since April, 2016 when I bought it. All of a sudden, 2 weeks ago, the 2G compartment stopped connecting to network. It refuses 2 SIM cards activeness on the phone and as such disrupts my call and browsing activities. The phone did not fall, I just can’t understand what’s happening.

Meanwhile, if I insert the SIM cards in other phones, they work well but in my S7, I can’t make calls, send messages, receive calls or browse with either of my two SIM cards . The network signal for the 2G compartment disappears, indicating 2 SIMs can’t be active at same time. I got your mail address from a Samsung forum Casey.  — Caseygem4u

Solution: Hi Caseygem4u. If you’ve already tested two known working SIM cards on this phone, then that’s a clear indicator that something is not working properly on the device. Make sure that it’s running the latest Android version by installing updates. If you are an adventurous type and recently flashed a custom ROM or rooted the device, make sure that everything is back to stock.

You also want to see what happens when you factory reset the phone so be sure to that if you’ve already installed all Android updates.

If the phone still fails to detect any SIM card, have it replaced.

Problem 1: Half of Galaxy S7 screen is not working after it got wet

Hello. My name is Annmarie and I am currently out of the United States at the moment. But I have a Samsung S7. I should start out saying that I have had the glass replaced by a non-Samsung company. I have taken my Samsung phone into the shower with me and it has gotten wet before without a problem. However yesterday my phone was dirty and I decided to rinse it off in the sink. My phone was not submerged in water and I only rinsed off the top.

Shortly after, my split screen button starting acting up and working on its own. So I stuck the phone in rice for a couple hours hoping that would fix it. After a few hours I took it out and it seem to be working better not 100% but better period.

Then I went out to eat with my boyfriend. And all of a sudden half of my screen went black. The whole left side of my screen was black however the touchpad was still working. I could still select numbers, however, I didn’t know what they were because the screen was black.

So I reset the phone hoping that would work. When the phone starts up, the Samsung logo appears normal on the whole screen, however once it gets to the carrier screen it goes back to being only half. This is a big concern for me because I don’t have money for a new phone.

Is this something that I could get covered under the warranty of Samsung or am I just out of luck? or is there possibly anything else I can do? Slight change the screen came back on, however the left side is frozen on the home screen. — Annmarie

Solution: Hi Annmarie. First of all, we want to make it clear to you and to others who may read this post that putting a phone inside a bag of rice is NOT a fix. It is just part of a series of steps that a user must do immediately to apply “first aid” to a water damaged electronic device. The goal of placing your phone in a bag of rice is to hopefully allow the device to lose tiny remaining moisture in places that’s difficult to dry out. Rice is supposed to absorb moisture and alcohol (that you must use to clean a wet device). If your phone has already suffered damage immediately after it got wet, drying the device in a bag of rice is useless.

Secondly, if your phone did not have this problem before you intentionally exposed it to water, the screen assembly must be permanently damaged right now. If you’re lucky and the problem is only isolated to the screen, replacing this part may bring your phone’s normal functions. Otherwise, you may end up with a phone replacement.

Problem 2: Galaxy S7 POP3 email won’t sync

Hi. I am battling, since a couple of days ago, to sync my POP3 email to my S7 Edge. The email account is working as I am still receiving emails on my laptop but just nothing is coming through on my phone. I have tried manually syncing from the settings >> accounts page, and the time stamp gets updated but in the email account >> settings when I look at the details, the timestamp has not updated the last sync’d time (which makes sense as nothing has come through, Have tried to play around with the sync options but no luck. Any suggestions? — Nicola

Solution: Hi Nicola. Did you check the possibility that the email you’re using may be the issue? If you haven’t, consider wiping the cache and data of the email app. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

If that won’t help, contact your email service provider for support.

Problem 3: Galaxy S7 overheating and keeps shutting down on its own

Hello 🙂 I have a Samsung S7 which recently switches itself off after about 5 minutes of use. It gets very hot and then just keeps switching itself on and off in a loop until you turn it off manually. I haven’t dropped it or got it wet. When it’s briefly on if you try to for example to message someone no keyboard will come up. I have tried wiping the cache, made sure my apps are up to date and deleted most of the apps. I’ve also tried turning it on in safe mode but none of these things worked. I was advised to try a hard reset but I’m currently travelling so cannot back up the photos etc and I don’t want to lose them! Any ideas?! Thank you in advance! — Clharwood1

Solution: Hi Clharwood1. An overheating device almost always results to random reboot issue because your Samsung device is designed to do just that. Too much heat  inside the phone can potentially damage components so your phone will automatically turn itself off once temperature inside reaches a certain point. Although random reboot issue can sometimes be the result of a bad app or software glitch, your case appears hardware in nature. To check, you need to do a factory reset and observe the phone afterwards for at least 24 hours, when there are no apps and updates installed. If it continues to shut down on its own, you can assume bad hardware is behind the trouble.

Problem 4: Galaxy S7 won’t charge from a power bank after an update

Since the latest update, the phone charges very slowly or not at all unless I use the Fast Adaptive Charge plug. I can’t use a power bank any longer, either. I had turned off the Fast charge capability because the phone got so hot, and was using a USB hub that’s plugged into an outlet. Fortunately, I realized I needed to go to rapid charge setting and plug. However, it would be nice to be able to use a power bank at certain times. Now, my boss says his Note 4 no longer charges with power bank. I suspect it just updated and is the same issue. Any thoughts here? — Trish

Solution: Hi Trish. We’re not aware of any recent Android update causing fast charging to stop working, or to cause the phone to overheat while charging, so this may be an isolated. There’s a lot of information that must be collected in order to know if this is an update issue so it’s really difficult to give you an accurate diagnosis. We suggest that you try a factory reset first and see how it goes. If the problem is caused by a software glitch, factory reset should fix it. Here are the steps on how to factory reset your S7:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Once you’ve factory reset the device, observe the phone for at least 24 hours and make sure that you don’t install anything (apps and updates). If the problem stays, have the phone repaired or replaced.

Problem 5: Galaxy S7 edge moisture detected error

Hi. I’m having major issue’s with my Galaxy S7 edge. Firstly, the USB cable wouldn’t charge my phone so I bought a new one. Then the phone worked perfectly for a week. Then I bought another charger lead then another. Then just last week, as I put my phone on charge I got a pop-up saying moisture detected. My phone couldn’t charge.

My wife brought the phone to our local Vodaphone shop and they sent it away. Long story short, they now are saying that it’s my fault. Never has my phone been near water or moisture.

I have bought a wireless charger. will this charge my phone when I get it back or will I continue to have problems? — Patrick-62

Solution: Hi Patrick-62. The “moisture detected” error only comes up if the device detects moisture in the charging port area. Samsung designed the Galaxy S7 to be water resistant but sometimes, moisture can be deposited in the hard-to-get area inside the charging port. To prevent causing damage to other components, the system will block any attempt to charge via USB cable, hence the “moisture detected” error. This does not mean that the phone is damaged though. To make the phone charge via USB cable again, you simply have to make sure that the charging port area is fully dried. You can do that by shaking the phone for a few minutes, or by using a hair dryer or hair blower to dry out the affected portion. When using a hair dryer or hair blower, make sure that you don’t apply too much heat as that might damage the phone. Getting the “moisture detected” error does not necessarily need sending the phone in as you can easily address it on your end. Just wait for your phone and we’re pretty sure it should be back to its working order.

And yes, using a wireless charger should work because wireless charging don’t need the USB charging port.

Problem 6: Galaxy S7 stuck in setup page after a factory reset

I recently factory reset my phone due to it not accepting any of my multiple attempts to do a complete system update. However since doing this, it refuses to let me past the setup screen. Every time I try to connect my Google account, or even try and skip the option, it repeatedly comes up with a notification saying “Unfortunately, Google Play services has stopped.”, to which it then sends me back to the beginning of the setup screen. Please help? — Georgia

Solution: Hi Georgia. There’s no way to skip the setup screen following a factory reset. If you’ve already tried doing another round of factory reset without success, the only way out may be flashing the bootloader and/or firmware. Below are the steps on how to flash a bootloader of a typical Samsung device. The exact steps may be slightly different for your phone so you want to make sure that you do some research. Remember, if flashing the bootloader won’t work, try to flash a stock firmware.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Problem 7: Unable to factory reset Galaxy S7 due to FRP

My husband’s Samsung Galaxy S7 is locked. We cannot get it to factory reset. Google, Verizon, will not help. We are at a loss. It keeps asking for the original Google account and password which my husband has no idea. Can you please help us? — Teresa

Solution: Hi Teresa. Samsung and Google introduced another security layer for Samsung devices over a year ago called Factory Reset Protection (FRP). This security layer protects a phone by preventing a user from doing a factory reset on it unless he or she can enter the Google account credentials associated with the device. For most average users, their Google account is usually the email and password that they enter when setting up the phone for the first time. Samsung and Google obviously assume that everyone remembers their Google account credentials that they don’t provide any official way to address an issue like yours.

Fortunately, Android community is an excellent bunch and has provided a few ways to fix this kind of trouble. We haven’t validated each of them yet but we recommend that visit Google and check the videos for a possible fix.

Problem 8: Galaxy S7 camera won’t take selfies

One is can’t do selfies because I always get camera error and have to go to settings and clear cache but never can take selfies if I wanted to. Second problem is can’t read books in Nook and only have this problem with Samsung S7 and no other device or Android device do I have this problem. — Nancy

Solution: Hi Nancy. To fix your camera problem, these are things that you should try:

Reset camera settings. We assume you’re using the stock or native camera app, which, like any other app, can become problematic. Sometimes, bugs can appear out of nowhere following an update or installation of a new app. In some cases, a more drastic troubleshooting is needed to fix a problem. In most cases involving the pre-installed camera though, simply resetting the settings can be an easy fix. If you haven’t reset the settings of the camera app before, here’s how it’s done:

  1. Open the camera app.
  2. Tap the Settings icon at the top right corner (the one that looks like a gear).
  3. Scroll down to the bottom and tap Reset settings.

Delete camera app’s cache and data. If the issue remains after resetting camera app settings, your next move would be to delete the app’s cache. If nothing will change after that, proceed with clearing the app’s data. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, find camera app and tap it.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the  Clear Cache and Clear Data buttons for the application.
  6. Tap Clear Cache and check how selfies work.
  7. Tap Clear Data if clearing the cache won’t help.

Use a different camera app. If, for whatever reason, selfies continue to fail, you then want to try using another app that can take selfies. There a lot of apps that you can try out there. Most social networking apps use the camera so you can try any of them. Your goal is to check whether the issue is specific to the camera itself (its hardware component). If the camera itself, and not the app, is not working, you won’t be able to take selfies regardless of the app you use.

Factory reset. If all apps won’t take selfies as well, do a factory reset to see if there’s a software glitch causing it. If the issue remains after a factory reset, you can bet it’s a hardware issue. You should have the phone replaced.

Problem 9: Galaxy S7 won’t turn back on after leaving uncharged for 2 days

Hi there. I wasn’t using my mobile for a day or two and the battery depleted somehow I guess and I am trying to recharge it, but unfortunately it’s not charging and not showing any sign of charging like the battery image shows up when you charge. It’s completely dead and won’t turn on, I have kept the phone on charging for hours now and turning it on is not helping. I have tried turning it on with Power + Volume Down key for 10 seconds, still no effect. Thanks. — Hassan

Solution: Hi Hassan. When the phone shows that the battery has 0% left, it’s not actually fully drained of power. A small reserve of energy is actually left there to give the battery circuit power to make itself ready to receive a new charge. Sometimes, physical damage, abnormal chemical reactions, or unknown battery issues can use up all power, including the small reserve, causing the battery to stop working permanently. This usually happens after leaving a battery unused for months on end. Your issue may be an isolated case since you said, you only left the phone uncharged for a couple of days.

Try to see if you can start the phone to alternate modes first. If the phone remains dead, you have no choice but to send it in.

Below are the steps on how to boot your S7 to alternate power modes:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Samsung Galaxy A5 no longer charges and keeps showing “moisture detected” error [Troubleshooting Guide]

When your Samsung Galaxy A5 starts popping up the “moisture detected” error, that’s when the charging stops. It’s designed to do so to prevent further liquid damage. You know all so well that electricity and water don’t mix well and if this happens inside your phone, your expensive device will turn into an expensive paperweight.

In this post, I will tackle this problem to make your phone work normally again. This isn’t the first we’ve encountered this issue so we already know a thing or two that could help you fix it. However, every case is unique unless it’s really a problem brought about by a firmware update. Continue reading to know how to deal with the ‘moisture detected’ issue.

For those who are looking for a solution to a different issue, visit our Galaxy A5 troubleshooting page for we have already addressed several issues with this device. Browse through the page to find problems that might be similar with yours and use the solutions we suggested. If you still need our help after that, contact us by completing our Android issues questionnaire.

Troubleshooting Galaxy A5 that doesn’t charge and shows an error

We will begin our troubleshooting by making sure this isn’t a liquid damage issue so that we won’t cause further damage to your phone. In case this problem is due to a liquid damage, we will try to determine how serious it is. If it’s something that’s beyond our league, then you still have an option to get a technician to take care of the problem but I hope that this is just a minor problem.

Verify it’s not due to physical or liquid damage

Had this problem occurred due to physical damage, then you would see some scratches or dents on the outside. If your phone’s appearance remains flawless, then you should try to figure out if this is due to liquid damage.

After ruling out the possibility that this issue is caused by a physical damage, try to check if the USB port is wet or has some trace of moisture. Take note that the error “moisture detected” usually pops up when the phone detects some moist in the port. If you’re not sure if the port is wet, use a cotton swab to clear around the area or you get a piece of tissue paper and insert it into the port; it will absorb the moist.

Another thing you need to do to make sure this isn’t a liquid damage issue is check the Liquid Damage Indicator which can be found inside the SIM card slot. Remove the SIM card tray to reveal if the indicator turned red or pink because if it did, then liquid damage is evident. However, if the indicator remained white, then at this point you can rest assured the issue isn’t caused by liquid damage.

RELEVANT POSTS:

Turn off your phone and charge

After making sure the error isn’t triggered by liquid damage, you can then proceed with the procedure that will replenish your phone’s battery. At least now there’s no fear that you will mess your phone up even further because we’ve ruled out the possibility that the problem is due to liquid damage.

It is imperative that you try to charge your phone because we will be troubleshooting and we can only do so much if there’s only about 5% of battery left. At this point, I want you to turn the phone off and then charge it. The error message that prevents the phone from charging only shows up if the phone is powered up as it’s handled by a service or two that loads up together with the firmware. But when everything is powered down, your phone should be able to charge properly.

However, there were cases wherein even if the device is powered down, the phone still refused to charge and in such case, you can try the next procedure.

Run your Galaxy A5 in safe mode and charge

We often suggest to run the phone in safe mode if it’s possible that the cause of the problem is a third-party app, however, in this instance we want you to run the phone in this mode so that it will only load all necessary service and apps. Some of our readers who have also encountered this problem suggested that booting in safe mode will allow your phone to fully-charge its battery. So follow these steps to run your device in safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

Make sure to plug the charger to a working wall outlet and then connect your phone to it using the original USB cable. If the phone is still not charging in this mode, then the next step will surely help.

Clear the cache and data of USB Settings service

One of the services that handles charging is USB Settings. It’s the one responsible why your phone is popping up the ‘moisture detected’ error but the thing is it also handles all other apps and features. But since you’re having a problem charging your phone, try to clear its cache and data so that it will be reset. You may then proceed with the charging of your phone.

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Apps.
  4. View contents of ALL tab.
  5. Find USB Settings and tap on it.
  6. Tap Clear cache.
  7. Tap Clear data and then tap OK.

Attempt to charge your phone after this and if it successfully charges, then leave it as is so that it would continue charging its battery. However, if the phone refuses to charge even after doing this, then it’s time to bring the phone to the tech as it might really be a issue with the firmware and need immediate attention from the tech.   

I hope that this troubleshooting guide can help you fix the problem with your phone. If you still need our help after this, feel free to contact us.

Problem #1: Galaxy S7 “Moisture detected. Make sure port is dry.” error after Android update

Hello. I read an article on your site about the “moisture detected” error message that appears on the Samsung Galaxy S7. I had the same issue happen to me when I tried to charge my phone this afternoon; however, my phone never got wet. I did not put it in water, nor did I touch it with wet hands or splash it with water. I tried a co-worker’s charger, and the error message did not appear; however, I used the charger that caused the error yesterday without issue. The only thing that is different since yesterday is the firmware update I completed overnight. I tried to search to see if any other update-related issues had been posted, but did not find anything similar to what I’m experiencing. Any help/suggestions you may be able to provide would be helpful. Thanks. — Shelby

Solution: Hi Shelby. “Moisture detected. Make sure port is dry.” error usually pops up if the system detects that the charging port is wet. We are yet to encounter a case wherein a Galaxy S7 shows a false alarm like the one you’re having but it’s not far fetched since it’s the operating system that issues such warning. If the phone has never seen water and the error popup started after an Android update, then it’s highly likely that there’s a firmware glitch behind this trouble. That said, doing the basic software solutions may likely be helpful.

The first step that you want to do is wipe the cache partition. This is an important yet simple solution to help ensure that the system works as intended. Sometimes, updates can corrupt the system cache so it’s good to make sure that you wipe the cache partition to force the phone to create a new one. Here’s how it’s done:

  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

If wiping the cache partition won’t resolve the issue, your next step is to do a factory reset. This will not only delete existing bugs but may also prevent new ones from developing. Refer to the steps below on how to perform it.

Also, it’s important that you ensure that only compatible and updated apps are installed on your phone. Developers are not required to update their products everytime a new Android iteration is released so there’s always a chance that bugs may occur due to poorly coded or incompatible apps. If you aren’t sure if an app is compatible or not, make sure that you check their Google Play Store page for information. You can also contact the developer for direct assistance is needed.

If you are fond of installing third party apps from non-secure sources, make sure that the developer has good reputation. Updating an app can be an easy or resource-demanding duty for a developer so make sure that you only install a good app. Unpopular apps are mostly unprofitable so there’s little incentive for developers in improving them further whenever new Android versions are introduced by Google. Try to stick with mainstream apps for your digital needs in order to minimize bugs.

Problem #2: Galaxy S7 turn on but the screen remains black

My phone is on but the screen won’t turn on. The notification light turns on and so do the back and menu button. I’ve tried holding down the power and the volume down button for 10+ second and the blue light becomes solid (stays on the screen not blinking) then there’s this God awful pop sound. Still doesn’t turn on. I’ve tried the other methods of turning the screen on, nothing. It may also be important to mention i recently had my cracked screen replaced. I didn’t notice until last night that the top of the phone was loose, like the screen would come off. PLEASE HELP! P.S. I don’t know what the version is. — Taylor

Solution: Hi Taylor. You clearly have a screen issue here. Obviously, there’s no amount of software tweaks that you can do to fix a hardware issue. The only resolution available for you is hardware repair. Kindly bring your phone to shop who initially fixed the screen so they can do the job properly this time.

Problem #3: Un-rooted Galaxy S7 stuck in bootloop

Hi. I tried to root my phone using Odin. Everything worked fine until I tried un-rooting my phone. The un-rooting process seemed to be working fine and Odin displayed a success sign indicating to me that the phone was now un-rooted. However, the blue reboot screen with the loading signal wouldn’t appear and it just went blank. Then the first picture with the words Samsung Galaxy S7 Edge appeared with “Powered by Android” at the bottom of the screen. It has stayed frozen on the screen ever since i un-rooted my phone. It won’t reset, I can’t soft reset or do anything with the phone anymore. PLEASE HELP MEEE! — Meihana

Solution: Hi Meihana. The first thing that you want to do here is boot the phone in Recovery mode so you can do a master reset. Below are the complete steps on how to do it:

  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

If master reset won’t help you, try to flash a stock firmware via Odin. Use Google to search for the correct firmware and guide.

Problem #4: Galaxy S7 won’t boot properly after using SnapChat

Lately I have been having problems with my phone freezing while on app and sometimes getting warm. Last night when I was using Snapchat, the screen went black. I got out of the app and everything else seemed fine but when I kept going back into Snapchat, the same black screen would appear so I powered off the phone. When I turned it back on, the Samsung logo appeared and all looked fine but 5 seconds into it, the phone restarted on its own and kept doing so over and over again. I tried manually turning off the phone and turning it back on but the same thing happens: the Samsung logo appears, the Galaxy S7 logo appears, my lock screen appears and then it vibrates and restarts on its own. What can I do that will NOT delete my photos and videos?

About a month ago I started updating my phone because I didn’t have enough storage before to do the update but ever since I started updating, the phone started to freeze. The phone still looks like new, no cracks, no falls, no water damage, charges great. Hope you can help me, thanks! — Rose

Solution: Hi Rose. An issue like this can be a product of a malfunctioning hardware or by a software glitch. Since you have not much option in this case, try to  check first if you can interrupt the bootloop issue by restarting the phone in safe mode. Here’s how it’s done:

  • With your phone turned off, press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

If you’re lucky and your phone will boot to safe mode, the first thing that you want to do is to create a backup of your files. However, if the issue remains and the phone continues to bootloop before or after engaging safe mode, the most likely reason for it is either a bad bootloader or malfunctioning hardware. There’s no way to know which of the two is happening so we suggest that you contact your carrier first to see if they’ve heard of other users experiencing the same issue after updating (assuming you installed an update from them). However, if you got the update from other sources, the problem can be traced on the bad firmware you’ve been using. Contact the developer of the firmware you used to see if there’s a fix they can provide.

If your carrier or the firmware developer can’t provide a resolution, consider having the phone replaced. This means that you will lose your files and there’s nothing that you can do about it.

Problem #5: Galaxy S7 keeps alternating between 3G and LTE signal | Galaxy S7 system time keeps changing on its own

Help! I recently did a factory restore on my Galaxy S7. Shortly after, 3 days or so, I had to refill my service. I Use STRAIGHT Talk which is a problem. My First mistake, The day I refilled my service the LTE would go 3G. So I’d restart my phone, then LTE would work for a minute then BAM 3G again. Then, a day or so later I looked at my phone and freaked out cause it was all the sudden 4 pm! I could have sworn it was barely even 1:30 a little while ago, wtf!?!?!

Well my phone had jumped 2 hours ahead. This problem progressively got worse until I finally said fuck it last night and did another factory restore. obviously that didn’t work. So here it is Sunday morning and I crack my eyes and look at my phone to see the time…FLY up outta bed cause OMG it like 9:47 and how did I ever sleep this late with my 16 month old in the next room and how horrible I am for doing so!!! Then I get her upstairs and the oven says 7:37 (which is still late for us lol) HELP!

I have done

  • hard reset,
  • Soft reset,
  • checked mobile data settings,
  • time and date settings.

I mean if the factory restore isn’t doing it well the fuck can’t wait to hear from you.

Also, do you know how I can update my software? Everything I have found says I’m so because I’m using Straight Talk Thank you. — Amie

Solution: Hi Amie. There may be a third party app that forces the phone alter the system time (and date) without your knowledge. Doing a factory reset will surely fail in this case, especially if you simply install the same set of apps afterwards. Factory reset simply wipes the device

Kindly do another round of factory reset and this time, make sure that you don’t re-install your apps right away. Simply observe the phone (without the apps) for several days so you will know if this issue is being caused by a bad app.

For your signal issue (about your phone alternating between 3G and LTE), we strongly suggest that you seek the aid of your carrier as it may be network- or account-related.

For your third issue, the answer depends on whether or not the phone is originally from Straight Talk. If it is, then the most probably reason why no update is not yet available is because the phone may be running the latest Android Marshmallow version. However, if this phone is originally not from Straight Talk (it may be from other carriers but was enrolled in Straight Talk’s bring-your-own-phone program), then there’s no way you’ll be able to update the phone other than do it manually via Odin. If you want to know more on how to do it manually via Odin, kindly do some digging using Google.

Problem #6: Galaxy S7 Edge camera distorts colors when using selfie mode

When I take a picture using the selfie mode on my Galaxy S7 Edge, I take the picture and it introverts the colors. But when I use wide selfie mode or any of the others it’s fine as well as the rear camera. I’ve never had a problem taking selfies before until last night. You know how there is the little box in the bottom right hand corner showing the last picture you just took? The Colors are fine like a normal picture, but once I open the gallery or click on the little box in the bottom right hand and open up the picture to see it, it introverted the colors of the picture.

Can you please help me? I reset the camera options. What else can I do with out resetting my phone? — Brooks

Solution: Hi Brooks. We’re afraid if resetting the camera options back to default did not fix the issue, the next and only solution you have is to factory reset the device.

But before you proceed with factory reset, try to go over your list of apps and see if you recently installed a third party app that uses the camera in some way. The same is true for other apps that can modify camera functions and can edit photos. Make sure that you uninstall them to see if there’s a difference. Otherwise, simply do a factory reset.
