How to troubleshoot Samsung Galaxy S7 slow charging issue

With its fast charging feature, the #Samsung Galaxy S7 (#GalaxyS7) is expected to fully-charge its battery quicker than usual that’s why many owners are complaining about slow charging issues when they notice the phone is charging at a normal pace.

By default, the fast charging feature is enabled on the phone but users can actually disable both wired and wireless fast charging options. But we received reports that some owners encountered issues like the phone isn’t fast charging while others said theirs are simply slow charging. Let’s try to take a look at this issue a little deeper to shed some light on the questions that’s in the minds of the owners.

Galaxy-S7-slow-charging-issue

Before going any further, here are a couple of problems we received from our readers that best explain the slow charging issue with the Galaxy S7:

My phone just takes too long to charge and I know it as a fact because the first few days I could fully-charge it in less than an hour. Now, it takes 3 to 4 hours of being plugged in before it reaches 90%. Did I get a bad unit or the battery needs replacement already? It is the new Galaxy S7, which I purchased brand new. Can you guys provide me some instructions on how to fix this? Thanks.

My Galaxy S7 isn’t fast charging and it worries me. I tried using the charger with a cord and I also tried the wireless but it’s not fast charging like it was before. Did I do something wrong? Is it a problem with the phone? Tried researching online and there are a lot of owners that also experience this problem so I’m kinda worried about it. Can you guys please help me.

Step-by-step Troubleshooting

There are problems we cannot fix on our own. The purpose of this troubleshooting guide is to determine whether the issue with your phone is minor and can be fixed by doing the basic troubleshooting procedures. Let’s try to rule out one possibility after another until we can square out what the problem is.

Step 1: Find out if your apps have something to do with the slow charging issue

There are two general categories for apps, pre-installed and third-party. Any of these apps can cause issues like this and while we can’t pinpoint immediately which one is the culprit or if they have something to do with it, we need to isolate the problem.

There have been a lot of reports suggesting apps cause slow charging problems because the more apps running in the background, the faster the battery drains. In this case, the apps drain the battery quicker than the phone can take in so even if you plug in the device, it will still take forever to fully-charge its battery.

Going back to isolating the problem, you need to boot your Galaxy S7 in safe mode:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7’ on the screen, release the Power key and immediately hold the Volume Down key.
  3. Continue holding the Volume Down button until the device finishes rebooting.
  4. You may release it when you can see ‘Safe mode’ in the bottom left corner of the screen.

You may have read something about viewing the Recent Apps screen and close all apps out. The procedure above does the same trick in one go, in fact, it temporarily disables all third-party apps leaving pre-installed ones running.

If the problem was caused by some third-party apps, then the device should charge (even fast-charge) properly in safe mode. So, while the device is in this state, plug it in to charge and see how fast it can replenish its battery. Since there are only a handful of apps running, there should be a noticeable difference in charging time.

However, if the charging is still slow, then at least one possibility has been ruled out. So, continue your troubleshooting.

Step 2: Turn off your phone and plug it in to charge

This step will help us determine whether the phone charges normally when there’s nothing running in the background. Assuming the first step was a failure or the phone still charged slowly, we are yet to determine whether the pre-installed apps have something to do with it or the firmware, the battery or if it’s a hardware issue.

If the problem was just an app or two or a firmware glitch, the phone should be able to charge normally when it’s off. It may even fast-charge considering the screen is off and that there’s a little chance the device will heat up.

In case the Galaxy S7 still charges slowly when it’s turned off, not charging at all or heats up while it’s plugged in, it’s most likely a hardware problem and as early as now, you should consult a technician immediately or you can bring the phone back to the store especially if it’s still a few days old so it can be replaced.

On the other hand, if your phone just charges fine when switched off, then it must be just a firmware issue and there’s a couple of things you can do or try to fix the problem. Proceed to the next step.

Step 3: Try deleting the system cache and charge your phone again

Others would suggest doing the system dump but I think this procedure can fix the problem especially if it occurred just recently and without apparent reason.

There have been reports of slow charging issues that were caused by minor or major firmware updates, unsuccessful app updates, and corruption of certain system caches.

Wiping all the contents of the cache partition is the best thing you can do at this stage, so follow these step:

  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.

After wiping off the cache partition, plug your phone again and see if it charges fine this time. If not, there’s another procedure you should try below.

Step 4: Bring the phone back to its factory default settings and try charging it again

In other words, reset the phone. You don’t have much of an option right now and considering the problem just occurred without apparent reason, there’s a chance something must have gone wrong with some of the data. You’ve already cleared the system cache, so this time, try deleting all the data but of course, make sure you backup your important files, music, videos, photos. If you have a microSD card, transfer them in and remove the SD card. Then, remove your Google account and disable the screen lock so as not to trip the anti-theft feature and then follow these steps:

  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.

NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.

  1. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  2. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.

  1. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  2. Once highlighted, you may press the Power key to select it.
  3. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  4. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  5. The phone will now reboot longer than usual.

This is the last resort and it’s expected that a problem like yours will be fixed by doing this procedure, if not, then it’s time to visit a technician or return the phone.

Solutions to Galaxy S7 common issues: won’t power down, slow charging, stuck in bootloop

Hello everyone! Welcome to our new #GalaxyS7 troubleshooting page. As the title suggests, we’re dealing with some of the usual troubles S7 users around are experiencing. We hope that we shed some light on these problems.

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 very slow charging issue, erratic charging issue

For the last 3 days, once each day in late afternoon I’ve noticed my battery was at about 25%, the phone felt warm, and shortly after I felt my phone buzz and it shut off. Twice it was in my pocket at the time out turned off. Today I was holding it and had just noticed it said 22% when it went black. Each time it would not turn back on. I plugged it in and it showed the battery symbol completely empty, and took quite some time, maybe 20 minutes, before it showed enough power to turn on. I have not had any recent updates that I’m aware of, and no recent new apps. I cleared the cache this evening after reading your troubleshooting guide, as well as disabling gear VR, and will see if that fixes the problem. However I’m going on a trip on Friday and need my phone to work so I thought I’d see if you have any other ideas! Thank you! — Monica

Solution: Hi Monica. Your phone may be experiencing a bad battery problem so the first troubleshooting step that you want to take is to recalibrate the battery. Sometimes, Android may lose track of the actual remaining battery power so it’s good if you can recalibrate the battery from time to time. Here’s how it works:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Charge the phone without turning it back on.
  3. Wait until the battery says it is fully charged to 100%.
  4. Wait for an hour before unplugging the phone from the charger.
  5. Use the phone until battery reaches 0% percent. The phone should turn off by itself.
  6. Recharge the phone to 100%, wait for an hour before unplugging it again.
  7. The battery should now be recalibrated. Observe how phone works.

If recalibrating the battery won’t help at all, that’s the time that you should consider returning all settings to their defaults, also known as factory reset.

To factory reset your S7, follow these steps:

  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.

Remember, factory reset will address software-related problems. If the phone continue to behave erratically while charging, or if it won’t charge at all, you can assume bad hardware is to blame. You’ll need to contact Samsung so the phone can be repaired or replaced. If it’s provided by your carrier as part of your subscription plan, try calling them to see if they can replace the device.

Sometimes, a charging port issue can also manifest symptoms you’re experiencing so you might want to try using a wireless charger. If charging will be back to normal (not slow or erratic), that can be a sign of a malfunctioning charging port. You still need to have the phone replaced but at least you can delay sending it in by charging wirelessly.

Problem 2: Galaxy S7 won’t power down, won’t unlock the screen

Hello. Let me start off by informing you that this is originally a T-MOBILE but i transferred it to my current metroPCS phone plan. And after i turned my phone off for a quick restart it is prompting me to enter my password and that i can use my fingerprints after i enter my password that must contain 4 characters and one must be a letter. And because of this i can not get into my phone to do anything and it wont let me power down the device either. Please help me. I must have my phone for work. Thank you.

PHONE DETAILS

Brand: SAMSUNG

Type:GALAXY S7

Model:SM-G930T

Carrier:T-MOBILE TRANSFER TO METRO PCS

Version 7 NOUGAT. — Jonathan Pazderski

Solution: Hi Jonathan. First, you want to ensure that your phone can turn on and off normally. If you’ll not be able to do that, something is definitely not right. To see if you can turn the phone down, kindly do the following:

  1. Press and hold the Power button (located on the right edge of the device).
  2. Tap Restart.
  3. Tap Restart again to confirm.

If you still can’t turn the phone off after trying soft reset, let the phone drain its battery and turn it back on.

Second, you’ll want to do a factory reset (only if the problem returns after charging). Be sure to boot to Recovery Mode first so you can also try to clear the cache partition before eventually doing a factory reset. Here are the steps on how to boot your S7 to Recovery Mode:

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

In case you’ll encounter problems unlocking the screen, there are three possible solutions that you can try:

  • unlock your device using  Android Device Manager
  • unlock your Note 5 using Samsung Find My Mobile
  • unlock the device by performing a factory reset

To unlock the screen using Android Device Manager, follow the steps:

  1. Go to the Android Device Manager from a computer.
  2. Find your Galaxy Note 5 on the screen.
  3. Enable “Lock & Erase” feature.
  4. Follow the given steps on the page to lock your phone.
  5. Set a temporary password.
  6. Enter the temporary password on your Note 5.
  7. Create a new password.

To unlock the screen using Samsung Find My Mobile, follow the steps:

  1. In your computer, go to Samsung Find My Mobile website and sign in.
  2. If you have multiple devices registered, make sure to select the correct one in the upper left hand side of the screen.
  3. Click on the arrow icon to begin searching for your device.
  4. Once the service has located the device, scroll down the options on the right until you see Unlock My Device option.
  5. Click Unlock My Device.
  6. Enter your Samsung password.
  7. Click Unlock.

Problem 3: Galaxy S7 stuck in bootloop

My Samsung S7 is stuck on a reboot loop. It shows the “Samsung Galaxy S7 powered by Android” screen, then turns black and keeps on doing this until the battery dies.

I’ve tried the factory reset and everything. When I hold the volume up, home and power buttons, it goes to the recovery screen. The bottom of the screen says supported API: 3 and under that, in red it says “dm-verity verification failed” If I hold the volume down, home, and lock buttons it goes to a blueish screen to download a custom os. If I press continue, it says it’s downloading but never finishes. If I do the factory reset thing, it just starts turning on and off again. — Kacie.dawn15xo

Solution: Hi Kacie. Hopefully there’s no hardware issue behind the trouble. If that’s the case, reflashing the bootloader may help you fix the problem. Below are the general steps on how to reflash a bootloader. The exact steps may vary depending on your particular model so be sure to do some research in order to find a good guide. The steps below are for demonstration purposes only:

  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.

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

Problem 1: Galaxy S7 edge screen won’t turn off, showing colored lines

The graphics on the ‘edge’ (right side) is permanently on even though I have all the Edge Screen features turned off. In fact you can see individual streaks of coloured lines which randomly change colour for no reason. It is as though its a graphic card failure. Even in sleep mode it’s on – either bright purple or green lines and there is no reason for it to be on. The colour overwrites ALL other display on the screen. Any help would be much appreciated. — Webbie047

Solution: Hi Webbie047. This screen behavior is usually indicative of hardware malfunction. If your S7 edge was physically impacted or dropped before, chances are the edge screen has been damaged.  Do a factory reset and see what happens from there. If the issue remains immediately after a factory reset and when there are no apps installed, you must contact Samsung to have it repaired.

For reference, here are the steps on how to factory reset your phone:

  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 2: Galaxy S7 edge screen stays black, won’t turn on

I’m using an S7 edge for the last 1 and half year but during this time i faced a lot of issues relating my phone.

First, i had an issue with the screen when i faced black line on the screen. the cell was under warranty so they changed the display as thy told me that it’s display has been crashed.

Then i faced a problem with hands free socket, i.e.,   while using hands free, outgoing call was not communicating while i can listen incoming calls

Third issue i faced is with dual SIM jacket. Sometimes just one SIM is working while the other stops working by itself

Fourth problem which am facing right now is that the screen gets freeze and then black after some time. i went to nearby Samsung service centre to update the software as thy told me its software problem but after 2-3 days working without interruption, it again started doing the same. Even i press the volume down and power button for more than 1 minute but it’s not working. I tried to press volume power and and main menu button (on front) but still its screen is black for the last 2 days. Unfortunately its warranty is also finished. Kindly show me some way out. — Muhammad

Solution: Hi Muhammad. The issues, when taken together, may have one and the same cause and that is an unknown hardware malfunction. We don’t know the full history of your device so there’s no way for us to identify what may be causing these problems. The most that you can do right now is to do a factory reset and observe the phone. Should these problems return, that means that you have a bad hardware. A technician needs to do a thorough hardware check in order to know where the problem lies. We can’t do that remotely so you really don’t have much choice in this one. We suggest that you return the phone to the shop that did the display replacement since they already know the history of your device.

Refer to the steps above on how to factory reset your phone.

Problem 3: Galaxy S7 screen is defective, does not register touches accurately

Third try it’s typing a letter off over or down-r gets a t-taping the x backspace repeatedly zooms screen and it won’t unzoom screen slides around erratically going sideways when scroll vertically spellchecker acting crazy filling in ie toll-free for toll-) I had to put the paran.there because it changed to toll-free when i tried to do the example also it seems to act like what ive seen of people playing games with rats-remote admin tools. A little mindful and inspired in the way the screen moves around as if on it’s own and switching or selecting when I haven’t a shade less than random or coincidental when im sure i just typed less up there i look back and see led ( like in around) repeatedly typos i dont think i did and that dont should have an auto ‘ maybe not sure its not my kind of fun i just typed kind and got kond could but have had the keyboard just typing off whole words when troed to correct it it kept typing a letter off type r and get t and every letter is a key off over or below. — Eero

Solution: Hi Eero. We don’t think we understand exactly what you’re trying to communicate here but if your screen does not work properly, you should consider sending it in. we assume you’ve already tried the basics but if you haven’t, you should do the following:

  1. wipe the cache partition
  2. boot to safe mode and observe the phone
  3. boot to recovery and do a factory reset

Wiping the cache partition should be the first troubleshooting that you should try. 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 the screen behaves erratically, you can also try observing your S7 while it’s booted to safe mode. If the cause of the problem is one of your third party apps, the screen should work normally. To boot to safe mode, follow these steps:

  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.

Just like in most Android troubleshooting, the last and ultimate step that you can try is factory reset. If the issue is still there following the procedure, you should have the screen repaired. Just forget about DIY (do-it-yourself) repair. A lot of them do not end up positive so just let a professional do the job for you. Sure you can find videos in Youtube on how to replace a screen and they appear easy to do but again, appearances can sometimes be misleading. If you think you can handle DIY repair though, go ahead.

Our blog does not provide hardware solutions including DIY tutorials so please look for sites like iFixit or Youtube to walk you through the process.

Problem  4: Galaxy S7 edge charges very slowly

I have a Galaxy S7 Edge. It has been charging in about 6 to 8 hours on wireless charger. Now it won’t charge overnight and says it needs 24 hours plus to reach full charge. I have NOT installed the upgrade nougat because of all the issues that I’ve heard about it I’m still running on 6.0.1. I’m afraid to upgrade to nougat because the last two phones I’ve had after the upgrade I have had lousy performance and short battery life to the point I ended up turning the phone in. — Jdelockery

Solution: Hi Jdelockery. The first thing that you want to do is to recalibrate the battery. This will retrain Android in detecting the true battery levels. Sometimes, Android can lose track of actual battery levels so recalibrating might help. Here’s how:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Charge the phone without turning it back on.
  3. Wait until the battery says it is fully charged to 100%.
  4. Wait for an hour before unplugging the phone from the charger.
  5. Use the phone until battery reaches 0% percent. The phone should turn off by itself.
  6. Recharge the phone to 100%, wait for an hour before unplugging it again.
  7. The battery should now be recalibrated. Observe how phone works.

Next, you want to check if fast charging feature is enabled. Just go Settings>Device maintenance>Battery>Advanced settings.

If fast charging feature is already enabled, then the next best thing to do is factory reset. If that won’t fix it either, then you can assume that either it’s a battery issue, or a motherboard malfunction. Either way, you’ll need to have the phone repaired.

Problem 5: Galaxy S7 won’t unlock screen, won’t accept PIN, fingerprint

My Samsung Galaxy s7 updated at 6am this morning and now my pin to unlock my phone. I am absolutely 100% sure that this the correct been because I have not changed it since I purchased the phone. My fingerprint unlock isn’t working either. I’ve tried restarting the phone and completely powering off. Nothing is working. I only have 3 more attempts before my phone factory resets. I’ve tried to go online to find some suggestions but I haven’t found anything but I have noticed that this is a common problem amongst Galaxy users — Jameraewing

Solution: Hi Jameraewing. There’s no way to unlock a Galaxy S7 edge that’s secured by a PIN or fingerprint. You must either do a factory reset or follow two alternate ways to unlock the PIN. These options require that your phone is connected to the internet, either via wifi or mobile data. If it’s not, just forget them and do a factory reset.

Samsung Find My Mobile option

Find My Mobile is Samsung’s equivalent to Apple’s Find My iPhone. Basically, it works by resetting the password temporarily and bypassing the lock screen.

  1. Register the Galaxy S7 with Samsung
  2. Use the Find My Mobile service to temporary reset the password
  3. Bypass the lock screen using the new temporary password
  4. Set a new password.

 

Android Device Manager option

Most Android devices can use this option because a user usually needs to input a Google account when setting up a phone the first time. Like Find My Mobile, ADM also requires that your phone is connected to the internet in order for it to establish a connection to Google servers. Make sure that you enter the correct Google account credentials. Below are the steps:

  1. In your computer, visit the Android Device Manager page.
  2. Find your Galaxy S7 phone in the screen.
  3. Enable Lock & Erase feature. Follow on-screen instructions to lock your phone
  4. Set a temporary password.
  5. Enter the temporary password.
  6. Create a new password.

Problem 6: Galaxy S7 edge won’t send SMS, keeps saying sending failed

New S7 edge on Straight Talk CDMA service. My text messages were working fine. Now when I send a message it sits there then says failed, however the message actually sends. How do I fix that so I know my messages sends? I’ve cleared cache restarted everything I’ve read. — Amanda

Solution: Hi Amanda. Did you clear the data of the messaging app? If you didn’t make sure that you do. If that won’t fix the problem, proceed to factory reset. If the problem returns after a factory reset, then try using a different messaging app like Facebook Messenger or Google Hangouts.

Problem 7: Galaxy S7 won’t charge, charging port not working

My phone is 3 years old. It has been having charging issues for a while now. I’ve tried new chargers and phone still won’t charge. I wiggle plug and once in a while it charges for a minute. Love the phone but don’t know what to do. Can you help? –Kim

Solution: Hi Kim. If the phone charges briefly when you wiggle the cord, the most likely problem is a bad charging port. Contact Samsung and let them check the phone. A charging port replacement may be needed to fix this one.

Problem 8: Galaxy S7 won’t send photos, won’t download photos

I cannot send pictures, download pictures or anything whether it be via email or txt message. I keep getting a failed download. I have gone on to my APN changed all the settings to giffgaff settings but still doesn’t work. it’s a recent thing as well and I haven’t changed anything. — Andrewxo

Solution: Hi Andrewxo. Your phone’s photo managing service may have stopped working or got corrupted so if you’re positive that you did not do anything different prior to noticing the problem, we suggest that you do a factory reset. This way, everything, including the service/s that handles photo sharing and downloads are returned to their known working state. See the steps above on how to factory reset your phone.

Problem 9: Galaxy S7 not showing pop up notification for incoming SMS

S7. I get my messages and can send them. It clicks to let me know I received a message but doesn’t pop up on my screen like it used to. It use to pop up even when I was texting someone but now I have to hit the back button to get to my messages. And if phone is off I need to turn it on to retrieve the message. — Patricia

Solution: Hi Patricia. Make sure that you set the messaging app you’re using to show notifications. We assume you’re running Android Nougat so here’s how to do that:

  1. Open Settings app.
  2. Tap Apps.
  3. Find the messaging app you’re using and tap it.
  4. Look for Notifications section and tap it.
  5. Be sure that Allow notifications slider is ON.
  6. If you want to receive notification while the screen is locked, tap On lock screen and select Show content.

If your messaging app is already configured properly and the problem returns, you may need to clear the app’s cache and data. Check the steps above on how to do it.

If nothing works, don’t hesitate to do a factory reset.

Problem 10: Galaxy S7 edge froze and won’t detect SIM card

Galaxy S7 Edge. Went to France and had a SIM card for French#. Worked great. On my way home, I changed the card back to my original card and now it doesn’t recognize it. I can’t use the touchscreen or turn it off. Help! What do I do? Thanks. — Kristen

Solution: Hi Kristen. Looks like your phone is frozen. You must try to do a soft reset to restart it. Simply do the following:

  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 cycle through the available options and the Home button to select.

If your phone still fails to re-instate the configuration for the original network, contact your carrier for support.

Problem 11: Galaxy S7 missing link preview in Messages app

I use to be able to see a website preview in my text messaging when a link was posted – but I had to do a factory reset and now all I see is the link. Is there a place I can go too in order to change that so I can see the website preview again? I can’t find it. Thank you so much for your time. — Jennifer

Solution: Hi Jennifer. At this time, link preview in Galaxy S7’s stock messaging app is non-existent. It’s only available in Galaxy S8 and S8 Plus. Until Samsung decides to add this feature again in older devices, all we can do is wait.

Problem 12: Galaxy S7 screen loses sensitivity when entering PIN

When I reset my Galaxy S7, when I get to the part to enter my password to start my phone, the enter button won’t work. like I hit it over and over until it finally works. I have factory reset and cleared my cache and booted on safe mode and still done it. Is there any way to recalibrate the screen? — Ddl1978

Solution: Hi Ddl1978. Have you tried a factory reset? If you haven’t make sure that you do.

Screen calibration is not supported in Samsung Galaxy S and Note phones. You either have a working screen or not. If the screen’s sensitivity has become problematic, you should send the phone in for repair.

Problem 13: Galaxy S7 camera won’t focus after camera screen was shattered

Yesterday, the little screen on my camera shattered. Unfortunately I’m not sure how. I gently removed it and the glue strip behind it and ordered a replacement. When I open the camera app now it doesn’t focus. I’ve tried both pro and auto mode. Is this because the screen is missing or has the camera itself been damaged? — Melanie.taylor

Solution: Hi Melanie.taylor. In order for the camera to focus properly, it needs a clear lens and glass cover. If the cover is obstructed and the camera can’t identify focus points, focusing may not work even if the camera itself is intact. Make sure that the lens is not obstructed by removing the broken glass cover. If that won’t work still, you can assume that the camera is broken. In that case, you must have the phone repaired.
