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

Problem 1: Galaxy S7 edge keeps restarting when opening links in a browser or app

Hi. My problem still persists: my S7 edge restarts on its own. I’ve read all your troubleshooting techniques and tried it all (uninstalled all the apps, removed SD card, soft reset, and hard reset). None of it worked. And soo sadly, it even got worse. The restarts usually only happened very minimal but after I tried the steps you said now even just browsing the internet I get restarts! It’s become too frustrating now. Here I thought I found my answer, so sad it was the opposite.

Anyway, I’m writing to inform that I’m not just complaining but asking for at least one method that works. Please do help. Thanks.

Again, my issue is the restarts. I noticed my phone restarts when I press links in my browser. And even opening certain apps. I know I have 3 GB of RAM so it’s impossible it be filled too quick. P.S. if you will say that there might be background apps running, the answer is no, there are time that just after I turned on my phone, minutes later of just basic browsing, it restarts. Please help. Thanks, I’m trying to give as many details as possible. — Giovanni

Solution: Hi Giovanni. Random restart issue can be due to software or hardware problem.  If all the software troubleshooting did not fix the restart issue, bad hardware must be to blame. Do a factory reset and see if your phone restarts when there are no third party apps installed. Make sure not to install any app or updates while observing the phone. You want to see to it that the phone runs a clean firmware. If the same problem occurs, that’s proof that no software hack can fix the issue for you. You should stop looking for a software solution and instead just send the phone in for repair or replacement.

Problem 2: Galaxy S7 stuck in loading screen after failed flashing procedure

I made an attempt to change a new unlocked ATT S7 Edge from ATT to the unlocked firmware. The phone is a G935A and I attempted to install G935U firmware using instructions on XDA-forums. After using Odin to do the download, I got error No support SINGLE-/SKU Supported Api:3 Dm-verity verification failed……. Need to check drk first…. Error code: 02 Phone is stuck at this location and it returns here even if I do a power down or reboot. I am not certain what step to take next. Can I attempt another download and how do I get phone into the download menu again is it with the power, home and volume down button press? — P22

Solution: Hi P22. You’re not supposed to use a firmware designed to work for a particular hardware build in another phone model. Doing so would almost always lead to problems. If you’re following instructions from a certain website, you should reach out to the community that provide them for support. We’re not aware of the instructions you followed (you obviously did not provide the XDA forum link) so we can’t check for ourselves if it’s problematic or not.

In general, some flashing-related issues can be fixed by flashing the stock firmware on the device. If you can’t find a fix for your problem right now, make sure to flash the original firmware version that originally came with your device.

To prevent this issue from happening in the future, make sure to do some research first to ensure that what you’re doing will succeed. Flashing is basically changing core system files and if you mess up a step, or if you use an incompatible firmware, you can expect problems like this to happen.

Problem 3: Galaxy S7 stuck in Verizon logo screen, making humming sound

So, my first problem is that this morning, i woke up around 7 and i looked at my phone and it was on the Verizon loading screen, i guess you can call it. I never turned off my phone completely before i went to bed and i don’t know how long my phone has been on this screen before i woke up but when i did, my phone was really hot. It’s the screen that when you turn your phone back on and it says the “Galaxy S7,” then it shows the Verizon logo with a red background.

Normally after the Verizon logo shows up, i’m able to use my phone within seconds but now none of the buttons are working. The reset button isn’t working and it’s been doing this for 3 hours at least.

My second problem is that for a few months my phone has been making a strange noise. it sounds like when your zooming in on a camera. the first time it happened a few times and it wasn’t that loud and it would only happen when i would go on snap chat. However the past few weeks the noise is getting louder to where I’m able to hear it loud and clear over my music and it happens every time i go on any app. What does this noise mean and how am i able to stop it? — Charleigh

Solution: Hi Charleigh. To try and fix both issues, you only have one attempt at troubleshooting — master reset. Like factory reset, this will reset all software settings back to their defaults, thus, effectively deleting all bugs that may have developed after some time. If the cause of the problem is software-related, master reset should fix both problems. Here’s how it’s done:

  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.

If the problem remains even after resetting the device, have it repaired or replaced.

Problem 4: Replacement battery on Galaxy S7 won’t hold a charge

My S7 has gone through 2 new batteries within the last 2 months. The person was taken back immediately after it failed to hold a charge. The second one I still have it doesn’t hold a charge either. the first thing I was taking back immediately after failed to hold a charge. The second one I still have and doesn’t hold a charge either. I follow the instructions of the place right where I bought the battery and kept it on charge for at least 12 hours before using. they offered only two types of batteries and are willing to give me my money back. I don’t know what to do in order to get this phone to keep a charge. It is very difficult to remove the battery. Please assist. — Vtrjr

Solution: Hi Vtrjr. You clearly have a phone problem here so it’s pointless to keep on changing batteries. If a new replacement battery did not solve the problem, there must be some power management issue on your phone. It can be bad motherboard or one of the components like the power IC. Consider getting a new instead of simply replacing the battery.

Problem 5: Galaxy S7 edge won’t charge or turn back on

My Samsung Galaxy S7 Edge has just recently started turning off. I will have it fully charged and then it will just die. I was able to use it for a while while it was plugged in, but as soon as I would unplug it it would die. Now it is at the point where it won’t turn on at all, not even while it is plugged in. It shows the charging symbol but it will never turn on or anything. I was recently able to turn it on for the first time in a while in safe mode while it was plugged in. But it stays at 0%. It won’t move. I’ve tried almost all the troubleshooting that I’ve read on your websites but nothing has worked so far. Got any ideas on what to do? Thanks! — Kelci

Solution: Hi Kelci. The only solutions we offer in our site are targeted for basic software issues only. If your phone does not turn back on, there’s hardly anything that you can do except to see if you can turn it back on to alternate modes. Unless you can do that, you can assume the issue is beyond your ability to fix and you must send it in.

Below are the steps that you can try 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 6: Galaxy S7 voice mail app not working all the time

For at least the last few months, I’ve had problems playing my voice mail messages. It will play a few words then stop. I hit the play icon again and it plays a few more words and stops again. This continues until I either give up or come to the end of the message. It doesn’t happen all the time, and doesn’t even always do that with the same message. I’ve called my provider at least twice about this issue, but they haven’t been able to fix it. — Marty

Solution: Hi Marty. This is either a problem on your carrier’s end or something in your device. If it’s an issue within the device, there’s a chance that it may be due to an app bug. To check, wipe the cache and data of the app and see how it works. 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 p in question 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 Data and Clear Cache buttons for the application.

If wiping the cache and data of the app won’t help, do a factory reset. Refer to the steps provided above.

Problem 7: Galaxy S7 cannot reply to SMS short codes

I have an unlocked Samsung S7 & I am unable to reply to business text messages. For example, my doctor’s office sends me a text message to confirm my future appointment. in the message it will say to reply with a certain “word.” I will try to reply back and it will say FAILED with a red exclamation mark. I use the messaging app that came with the phone. — Sky.lexx2

Solution: Hi Sky.lexx2. Only a select few and older Samsung devices provides a user to either deny or allow permissions for premium SMS or SMS Short Code. The Galaxy S6, S7, and S8 should automatically be able to reply to SMS short codes, unless your carrier or the app you’re using is blocking it. Kindly work with your carrier to fix this issue. Like most SMS and MMS issues, this problem is best addressed by your network so you have to work closely with them, especially if your phone came from them. For those using phones that are not provided by their carriers, the option to received or reply to SMS short codes may not be available.

Problem 8: Galaxy S7 not showing notifications

I have a few apps such as Facebook, vivint sky, groupme, etc that when I get notifications, the notification will flash but will not remain in the notification area like my email and text message notifications.  I’ve only had the phone a few months but I don’t recall it doing that when I first got the phone. — Gwen

Solution: Hi Gwen. You may have inadvertently changed the notification settings of the apps in question. Below are the things that you should do to check:

  1. Open Settings app.
  2. Tap Notifications.
  3. Look for the app you want to turn notifications for and tap it. This will turn on notifications for this app.
  4. Tap ADVANCED at the upper right hand side.
  5. Select the app you want to set the notifications for.
  6. Select the setting you want. The explanation for each option should be easy to understand.

Problem 9: Galaxy S7 Bluetooth keeps turning off wifi

Bluetooth keeps coming on and shutting my Wi-Fi off. Sometimes it does it when it shuts off, it will come back on and this will happen. Sometimes it just does it while my phone is in idle. sometimes it does it while I’m using it. — Lisa

Solution: Hi Lisa. Wipe the cache partition first and see how it goes. Should the issue remain, do a factory reset. Refer to the steps above on how to do both procedures.

Problem 10: Galaxy S7 not receiving Nougat update

My Galaxy S7 still has not updated to Nougat. What should I do?         — Liam

Solution: Hi Liam. If your phone was provided by your carrier, which means that it was given to you as part of your subscription plan with them, make sure to contact them for answers. Carrier-provided phones usually receive updates via OTA (over-the-air), that is, by downloading them via your carrier’s network. If you haven’t received any Nougat update right now, there may be some issues that only your carrier can fix. Alternatively, you can install Smart Switch in your computer and you can connect your S7 to it via USB cable. If there’s an available update, Smart Switch should prompt you for it.

Now, if your phone is an unlocked version from a different carrier, you can’t hope to receive any Android update by air. You can’t install a firmware version from another  in a different device. For example, if you have an unlocked ATT S7 and you’re now using it in T-Mobile network, T-Mobile won’t send you an update because of incompatibility. Again, you can try to use Smart Switch to see if there’s any available update.

If you want to update the device by a different means, you can also try what’s called flashing. Flashing is an Android term similar to installation in Windows environment. If you want to manually update your device via flashing, look for a good guide online.

Keep in mind that flashing can potentially damage your phone’s software if not done properly. Using an incompatible firmware version can lead to problems so make sure you know what you’re doing before actually doing it.
