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

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.
