Galaxy S7 turned itself off and won’t turn back on after an update

Problem: Hi. My phone is a Galaxy S7. Recently, there was an update that I downloaded and installed. Was able to use the phone for a couple of days since the update and then it turned itself off without any cause and now it won’t turn back on. Tried everything I can think of but the phone is just dead. Is it possible I installed a bad update? Please help me. Thanks! — Juris

Troubleshooting:  Hi Juris! This problem happens all the time and I’m sorry you’re one of the owners who encountered. You can rest assured though that if the problem is with the firmware due to the recent update, then you can fix it without help from a technician. That being said, here are the things you can do to troubleshoot it:

Step 1: Do the Forced Reboot procedure

This will rule out the possibility that the reason why your phone isn’t turning on is because the system crashed. When this happens, the device won’t respond when you press the Power key and it won’t also respond when connected to the charger.

To force reboot your phone, press and hold the Volume Down button and the Power keys together for 10 seconds.

If the phone reboots, then problem solved, otherwise, you should verify if the battery is totally drained or not.

Step 2: Plug the phone in to charge and leave it for 10 minutes

If the battery is all drained, of course the phone won’t respond when you press the power key. So, if the first step  failed in bringing the phone back to life, verify that the battery has enough power to turn all components on and load all services. Plug in the phone to charge for at least 10 minutes before attempting to turn it on again.

If it’s still unresponsive, then try to do the Forced Reboot procedure while the device is charging. Had the problem been caused by any other factors and not a hardware issue, then it should reboot.

Step 3: Try booting your phone in safe mode

After the first two steps and the problem remains, let’s try to exhaust all possibilities. Another factor that may also lead to this problem when some apps crash and affect the overall performance of the phone. More often, it’s the third-party apps that have a tendency to go rogue. Therefore, booting in safe mode is the next most logical procedure you should try as it temporarily disables all third-parties. Here’s how you 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.

Step 4: Try booting your device in recovery mode

If your phone cannot boot up in safe mode, then let’s try to see if it can boot into the recovery mode. In this mode, all hardware components are powered up only that the Android user interface isn’t. If successful, you can proceed by wiping the cache partition to delete all the system caches. 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.

In case your device still won’t boot up in recovery mode, then you have no other option but to bring it to a shop and have it checked as it is more likely a hardware problem that occurred after the update.

Galaxy S7 cannot boot up successfully after a minor update rolled out by carrier

Problem: My service provider had this update that we subscribers are forced to download. Long story short, after the update, the phone just won’t turn on to the home screen like it did before. The screen remains black after the logo. I actually tried leaving the phone like that for a few hours thinking it might load everything back but it didn’t. Sometimes, it gets stuck on the logo and there are times when it reboots and get stuck on the same screen. What gives? Can you shed some light into this issue? — Josh

Troubleshooting:  More often than not, when a device get stuck during boot up after a firmware update, it’s the system cache that has some issues–it might be corrupted. The thing is the new system may still use the old cache which may result to some serious firmware-related issues like this that will render your device useless. Therefore, the first thing you should do is wipe the cache partition. Try to follow the instructions in the previous problem on how to delete the system cache. After which, your phone may reboot successfully and you may not need to continue troubleshooting. However, if the problem remains after wiping the cache partition, then you should reset your phone because perhaps, it’s not just the cache that got corrupted but also the data. 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.

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.

In case the issue remains after the reset, the firmware may need to be reinstalled. If you know how to do this, then proceed at your own risk, otherwise, let the technician do it for you.

Galaxy S7 screen is black but blue lights keep flashing as if there are messages

Problem: I hope you guys have encountered this problem already. My phone is a Galaxy S7 that I bought about 4 months ago. It’s an international version but I got it activated in one of the providers in the United States. I’ve been able to use the device without any issues the entire time until the update came and the problem started. For a couple of days now, the screen of my phone is black but there is this blue light that keeps flashing as if I have messages. When I call my number, it won’t ring and when I charge the phone, it won’t charge. Do I have to send it in for repair or is there something I can do to fix it? — Melo

Troubleshooting: Hello Melo! Apparently, it’s just a system crash. This what happens when the firmware itself crashes. Fortunately, it’s easy to fix this problem…

  1. Press and hold the Volume Down button.
  2. While holding it down, press and hold the Power key and keep them held for 10 seconds.

The device will reboot and the problem is fixed but if it occurs again, then backup your data and do the reset.

Galaxy S7 dipped in water and won’t turn on after that

Problem: I got careless and my phone fell into a kiddie pool but I picked it out immediately. Moments later, it turned off and when I tried to turn it on the screen flickered for a few seconds and then went black. Tried turning it on again but it doesn’t respond anymore. Is it damaged or something? I thought this phone is supposed to be waterproof? Why is it that it went crazy after a few seconds in water? Can this be fixed? Thanks for your time. — Janice

Suggestion: Hey Janice. Obviously, water got into your phone and messed it up from the inside. Let me answer one of your questions…actually, the Galaxy S7 is water-resistant and not entirely waterproof. Besides, there are spots which liquid can enter like the charging port, headphone jack and there’s the space between the cases.

The answer to your other questions is quite obvious and the only thing you can do for it now is to let the tech take care of it for you.

Galaxy S7 screen won’t turn on or occasionally go green after being dropped

Question: I dropped my phone and received a small set of cracks in the lower right corner of the phone. Every since then, the screen will not come on or occasionally go green. I can still receive calls, but unable to see anything. Sometimes this happens for long periods of time (now I use a backup cheap phone) and sometimes briefly. What I noticed is when I’m using the backup phone, and the sim card in my S7  is de-active, the screen NEVER goes off…not once. But as soon as I re-activate the sim and resume using the s7 the occasional “blackouts’ occur which lead me to believe that it’s not a hardware problem. Please help…—Richard

Solution: Hello, Richard! Based on your statement that you accidentally dropped your device and resulted in having a crack in the lower right corner of the device. Let’s go back to the time before you dropped your device, have you experienced random green display? If not, then we have reason to believe that it is not a software issue and most likely screen issues.

We don’t have an idea how high you dropped your device is, but since it caused a cracked to your device then it must be pretty strong drop.

We’ve received several emails from our readers related to your issue, the only way to fix the device is to change the screen itself or device exchange. Then we highly recommend calling the Samsung tech support or the store you bought your device for possible fix. If the warranty is still active and covered accidental damages, then it’s good news.

Galaxy S7 freezes when it goes into idle mode or when not in use

Question: Hello, my phone would just freeze when not in use, like after going to sleep overnight. This happened basically a day after receiving the phone. I would see the flashing notification lights but the phone would be unresponsive. It also happens sometimes shortly after doing a reboot within 3 hours. One time it was fine all day then froze at 7pm. I tried all the fixes from resetting to factory reset and the problem still persists. One time I did a cache wipe and the phone was rendered almost useless…it froze about 3 times within half an hour. So does this mean that the phone itself is defective? Should I return it? — Kenge Hunte

Solution: Hi, Kenge! It’s a good thing that you did a factory reset and wipe cache partition your device to fix the issue. But, it seems that the problem still remained and your device freeze randomly, it is an indication that your Samsung Galaxy S7 is experiencing a manufacturer defect and cannot be fix by basic troubleshooting procedure. The best thing that you should do is to call Samsung or the store where you purchased your device. Bring the necessary documentation and if the warranty is still active, they might be able to replace it with a new one.

Galaxy S7 no longer charges after water found it’s way into it

Question: I was brushing my teeth while listening to music on my Samsung Galaxy S7, I placed it by the sink while brushing my teeth. Later, I realized water had entered into the phone and more over the battery was almost dead. So, I left it to dry and placed it in rice for some few hours. Fortunately, it started working again but had issues with the charging. It takes long time to charge than usual and sometimes instead doesn’t charge at all…it’s not stable.

Solution: Samsung Galaxy S7 is a water-resistant device but not water proof. If you accidentally dropped it in the water even for a few seconds there is a possibility that issues will occur without apparent reason. In your statement, your phone refuses to charge the water might be penetrated its charging port. So, performing troubleshooting procedure won’t do any good on your phone. The best thing to fix your device is to bring the device to a tech and let them inspect if for issues.

Galaxy S7 shows “Unfortunately, WFC Settings has stopped” error

Question: Receiving message, “Unfortunately WFC settings have stopped.” My daughter has the same phone and she doesn’t have this problem. I have had my phone since September and this error message just started appearing last week.– Tina

Solution: Wi-Fi calling or WFC is a feature integrated into the system of the device wherein user can use it for calling, sending and receiving messages without using a cellular network. However, if error message pops-up without apparent reason, then there might be an issue in the firmware of the phone or the Wi-Fi calling app needs to be updated.

Since, we are not certain what triggered the error message pops up on the screen, the best way to determine is to do the basic troubleshooting on your device. These procedures would not only help you identify what caused the issue but to fix it as well. To do so, follow the steps below:

Step 1: Clear the Cache and data of the Wi-Fi calling app

Assuming that you already activated the app but the issue still happening, clearing the cache and data is the first thing that you should do. By deleting all old caches and data stored in the app is somehow bringing back the app to its factory default. By doing so, there is a big chance that the issue will be fixed. To do so, follow the steps on clearing camera app cache and data above.

Step 2: Check if there is any available app update

One of the factors that app is crashing or an error message pops up on the phone screen it’s because app might be outdated. In fact, there were reports from other users saying that after updating the app the issue was instantly fixed. This time, we recommend you to update the WFC app by launching your Google Play Store and check if there is available update. If so, update the app and observe for any changes on your phone. If the issue still remained, then you can jump to the next troubleshooting procedure.

Step 3: Run your Device in Safe mode

If this issue is caused by third-party app, then we recommend running your device in Safe mode. You can still run your device normally using pre-installed apps, all third-party apps are disabled while in this mode. If the error message won’t display while in this mode then you can easily remove the app causing issue while in Safe mode.

If the error message still occurs after running in Safe mode, then we recommend using another Wifi calling app, there several apps available in Google play store.

Galaxy S7 smartphone keeps crashing

Question: My Samsung Galaxy S7 is crashing often. Originally, I thought it was due to a problem with Firefox but now it seems to not have anything to do with that.  It will be fully charged, crash and 6 to 8 hours later be rechargeable and show 0 charge. It has finally booted but crashed again, that is 19 hours after it seemed to suffer a fatal crash. Tried cleaning the cache, but afterwards, wouldn’t even show that menu. Could this be a dying battery? – Marcdm

Solution: Randomly crashing and not charging even it is connected to a charger can be one of the factors that the device has a firmware issue. However, if the battery is defective it is also possible that your phone won’t charge and shuts off without a reason.  At this point, the first thing that you should do is to troubleshoot the issue to determine if it is firmware or hardware issue.

Step 1: Forced reboot your Samsung Galaxy S7

More often, system crash is one of the reason that your device randomly shuts off or unresponsive. We recommend to force reboot your device, it is equivalent to battery pull for devices that has removable battery. To force reboot, press and hold the Volume Down and Power key at the same time for 10 seconds and wait until your phone will reboot successfully.

But if the issue persists you can perform the next procedure.

Step 2: Charge your device for 10 to 20 minutes

There’s an instance that the battery is totally drained or broken. To determine if it is a battery issue, let it charge for about 20-30 minutes then try turning on your device. Try changing your battery if you have an extra available just to make sure if your device will boot up.

Alternatively, try using wireless charger if you have. By doing this, you will also be able to determine which has issue either the charger or your device charging port.

Step 3: Boot your phone into Safe mode

In this mode, all third-party apps will be stopped and only the pre-installed apps will run in your device. This is not a solution to the issue but to make sure your device will respond and boot up in this mode. Charge your device while in this mode for about 20-30 minutes and see there’s a progress.

  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.

But if the problem is still happening after the safe mode perform the next procedure.

Step 4: Boot your phone in recovery mode

By booting it in recovery mode the components of the device will be powered up and if there’s no hardware issue it will turn on normally. To do so, follow the procedures below:

  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.

Step 5: Bring the device to the nearest local service center

You’ve performed most of the necessary basic troubleshooting steps to fix the issue but to no avail. This is the time you need to bring your device to the nearest Samsung service center to have the professionals help you fix the issue. Your device might be experiencing a serious issue that cannot be resolve by these procedures. Bring the necessary documentation as well like the warranty of this device if it’s still active.

How to troubleshoot Samsung Galaxy S7 that won’t turn on

You’re staring at a black screen on your new #Samsung Galaxy S7 (#GalaxyS7), wondering what to do because it turn on when you press the #Power key and it won’t respond no matter what. It’s new and it was working fine yesterday, left it lying on the table overnight with enough battery but in the morning, the screen is just black. What could have happened?

A few days after the Galaxy S7 was released, there were already owners that complained about their devices that won’t turn on. In fact, we already received a few complaints about this problem and so we publish this troubleshooting guide to address this very specific issue encountered by our readers. Read on to learn more about this problem and how to fix it.

Problem

Hi! I have the new Samsung Galaxy S7, it’s still 5 days old and it has been working since day 1 without issues until today. The screen is black and it looks like it has turned off. I tried to turn it on but it won’t. Tried charging it but it won’t respond either. I know I can go to the store where I bought it and have it replaced but it’s a 40-mile drive, so I want to try a few things first before heading out. What would you suggest I do to try to fix this problem? Thanks.

Symptoms and Possible Causes

Aside from the obvious black and unresponsive screen, there are other symptoms you may encounter when your new phone has this problem:

  • LED indicator is lit up but the screen is black and unresponsive
  • Screen is black, LED indicator is not lit and phone won’t turn on if Power button is pressed
  • You can hear the notification sounds but the screen is black
  • Device just turn off on its own and refused to power back up

This issue is common to all smartphones. In fact, we did receive hundreds of issues from our readers who encountered this problem using previous Galaxy models and among the most common causes are the following:

  • Battery completely drained that it takes a few minutes before the phone responds to the charger when plugged in
  • The Android system crashed leaving the phone unresponsive when the power key is press or if the charger is plugged in
  • Some downloaded apps keep crashing that also caused the system crash
  • The power key got stuck or damaged after the phone fell on a hard surface

Now, before we head to the instructions on how to troubleshoot this problem, if you have other problems visit our Galaxy S7 troubleshooting page as we may have already addressed your concern. Or, you can directly contact us by filling out this questionnaire. Please provide all relevant information about the problem so we can provide you with an accurate solution.

Step-by-step Troubleshooting

More often than not, won’t turn on issues are caused by system crashes. When it happens, the device won’t respond when you press the Power key and it won’t charge if you plug it in. It’s because the firmware plays a big role in starting up the hardware as well as charging the battery. So, here’s what you need to do in case this problem occurs…

First step: Force restart your Galaxy S7

By pressing and holding the Volume down and Power keys together for 10 seconds, your phone will perform the simulated battery disconnect. It’s just like when you pull the battery out of your phone to reset it.

This procedure is hardwired so it should work as long as it’s done correctly. Again, just press and hold the Volume Down and Power keys together for 10 seconds to do this.

Moreover, the Forced Reboot procedure will refresh the phone’s memory so whatever firmware and/or hardware glitch that occurred would be fixed immediately.

What if the forced reboot procedure failed?

Second step: Plug in your Galaxy S7 to charge

Maybe the reason why your phone turned off and won’t turn back on is because the battery got drained. It might also be the reason why the Forced Reboot procedure failed. So, it’s time you plugged the charger in and leave the device for, at least, 5 minutes before attempting to turn it on.

After 5 minutes of charging, try turning on your phone and if that won’t work, try the first step again.

Third step: See if the Galaxy S7 can boot in Recovery Mode

Now, this procedure will tell us whether it’s just a firmware issue or a serious hardware problem. In recovery mode, the Android GUI won’t be loaded during boot up but all the essential components will be powered up. So, if the phone boots up in recovery mode, it means the problem is with the firmware, probably. Otherwise, it’s a hardware problem.

  • Press and then hold the Home and Volume U 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.

If the phone can successfully boot up in recovery mode, proceed with wiping the cache partition using the Volume keys and the Power button to select the option and then try to boot up normally. However, if the recovery mode procedure failed, proceed to the last step.

What if the phone refused to boot up normally after the recovery mode?

Fourth step: Try booting the Galaxy S7 in safe mode

There’s a chance the problem was caused by a third-party app that may have crashed considering there are still apps in the Play Store that have compatibility issues with Android M (Marshmallow). In this case, you need to boot your phone safe mode just to see if it can and to rule out the possibility of the hardware problem once and for all.

  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.

If your phone successfully booted up in safe mode, try to uninstall suspected apps. Or, you can proceed with Factory reset through Settings or Master reset by booting up your phone in recovery mode again. Either way, the problem will be fixed. However, if the safe mode boot up was unsuccessful, then the last option is the last step.

Last step: Have the technician troubleshoot the problem or have the phone replaced

At this point, you did everything you could to try to fix the problem without compromising the phone’s safety and voiding the warranty. It’s time you went to the store where you bought it and let the technician check it for you. If the problem can’t be fixed by the tech, you will receive a replacement unit.

How to fix Samsung Galaxy S7 black screen of death with blue light flashing [Troubleshooting Guide]

Hey guys! In this post, I will address the black screen of death with the #Samsung Galaxy S7 (#GalaxyS7) as we’ve received several messages that basically contain the same complaint. Majority of them reported that their devices turned off and won’t turn back on while others said theirs have a black screen but with blinking blue lights.

Galaxy-S7-black-screen-of-death

The most common reason why the screen turns black and the phone won’t respond is a system crash. When the firmware hangs or freezes, the phone will be left unresponsive and all other services may also crash. That’s the reason why the screen turns off and won’t turn back on no matter.

Read on to learn more about this issue and how to deal with it. For average users, we don’t usually suggest complicated procedures that are potentially harmful to your device. So, if you are comfortable tinkering your device, then try the ones I suggested below.

For our readers who have other concerns, visit our Galaxy S7 troubleshooting page for we have already answered a lot of problems with this phone since its release. Find problems that are similar or related to yours and use the solutions we provided. If they don’t work or if you need further assistance, then you can always contact us by filling up our Android issues questionnaire.

Galaxy S7 screen is black but with blue lights blinking

Problem: For some reason, my new Galaxy S7 turned off, or so it seems, and won’t turn back on. However, there’s this blue light that keeps blinking as if it’s telling me that there are some unread notifications or messages. When I hit the Power key, nothing happens, it just won’t respond or turn on. Help me because the phone is barely a month old and it’s a hassle bringing to the store to have it fixed. Besides, I have sensitive work-related data in my phone that I haven’t backed up yet. I don’t want to lose them nor let somebody see them. Your help will greatly be appreciated. Thank you!

Troubleshooting: The fact that you can see a blue light blinking is evident that the phone’s hardware is fine and more often than not, black screen issues accompanied by lights or sounds are often the result of a system crash. I think that’s what’s happening to your phone.

Before I give the solution, let me explain briefly why I think it’s just a system crash. When it happens, everything in your phone stops responding and the display turns black. The Power key won’t bring the phone back to life. Charging won’t do any good either. There are cases wherein you can actually make a call to your phone number and you can hear it ringing on the other phone but your device still won’t respond.

The solution is to perform the forced reboot procedure, which is the equivalent of battery pull for devices that have removable batteries. All you have to do is press the Volume Down button and the Power key for 10 seconds. Provided there’s enough battery left to power up its components, the phone should start, otherwise, plug the charger in and leave the phone charging for 10 minutes and then try again.

The forced reboot procedure will fix the problem, however, we don’t know what caused the system to crash. So, closely observe your phone and if the same problem happens again, I suggest you backup your data and do the master reset to bring the phone back to its default settings. Here’s how…

  1. Backup your data.
  2. Remove your Google account.
  3. Disengage screen lock.

Galaxy S7 display is totally black, phone won’t turn on after update

Problem: There was an update that I downloaded yesterday and I think it went through without any problems at all. The phone rebooted after the update and I was able to use it for a few hours and then it just turned off. When I pressed the Power key, the screen seemed to light up a bit and turned off again. Since then, the device isn’t turning on. I have yet to let a technician check it out but if you how to troubleshoot it, that would be great.

Troubleshooting: Just like what I suggested in the first issue, this might be another variation of a system crash. I’ve seen a lot of issues like this in the past and still seeing some not only with Galaxy devices but with other brands including iPhones. Therefore, the first thing I want you to do is press the Volume Down key and Power button for 10 seconds, if the device’s screen remains black, then here are some things you can do:

Step 1: Charge the phone

Obviously, it will rule out the possibility of a drained battery and since you didn’t mention trying to charge your phone in your description, I thought that maybe you haven’t tried it yet. Of course, use the original charger and cable of your phone so as not to complicate things. If the phone is still not responding when plugged in, leave it for 10 minutes and then do the forced reboot (Volume Down and Power keys) but this time with the device plugged in.

In case the phone refuses to charge, then we are dealing with a phone that has a drained battery and won’t charge. It’s imperative you solve the not charging issue first before you proceed with other troubleshooting. Here are some guides we’ve written about charging issues with the Galaxy S7:

In case your phone still won’t charge, then don’t waste any more time. Send the phone in for checkup and/or repair.

Step 2: Try booting the phone in safe mode and recovery mode

Assuming your phone charges fine and displays the usual charging signs like the charging icon on the screen and the LED notification at the top of the display but still won’t turn on, then try to boot it up in safe mode first. This will rule out the possibility that one or some of your third-party apps is causing the problem.

  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.

If the phone still won’t boot up in safe mode, then try booting it in recovery mode:

  1. 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.
  2. When the Samsung Galaxy S7 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. 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.

Step 3: Send the phone in for repair

After doing all these things and your device is still not responding, then it’s time you sent the phone in for repair. As far as troubleshooting is concerned, you’ve done what you need to do as an average user. There’s a possibility that it’s a hardware problem.
