Galaxy S7 Edge won’t turn on after screen started to flicker

Problem: I bought an unlocked Samsung galaxy s7 edge from best buy in the very end of May of 2016. Now, it won’t turn on properly. About a week ago, my s7 edge didn’t turn on, and instead it flashed a white, sometimes green screen. After a few tries, it would turn on, however the screen would flicker and shake a lot. I have tried to reboot it, and restart it, however it does nothing. It’s been a week, and now the phone won’t even turn on after a few tries.

Troubleshooting: Hi! Honestly, we’ve received several emails from our readers that has related issue. Most of them were experiencing a hardware issue because of their device’s screen flickering problems and the only resolution is to change the display panel. Their devices are responsive, it will turn on normally but it has no display and sometimes it flickers and turns white or green, it is related to what your device’s. But, there are instances as well that the issue is caused by a system crash, so you can set aside the hardware issue for now. We will recommend several troubleshooting steps to determine whether it is a software or hardware issues. Below are the steps to follow:

Step 1: Run the device in Safe Mode

If this is a software issue you can try booting your device in Safe mode. This mode is not a solution of the issue but to make sure if your device is still responding and can boot up smoothly. It will disable all the third-party apps running only the pre-installed or default app. Here are the steps how to boot in Safe mode:

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 EDGE’ 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.

While in this mode, you can try using your device and uninstall the suspected third-party apps or clear the individual cache file and data of each apps like your games, facebook, etc.. Try to remember the app that you are using before the issue occurs.

How to clear cache and data, follow these steps: Go to Apps > Settings > Applications > Applications Manager > Select the app you want to clear cache and data > Clear cache > Clear data. Then, go back to the main screen and you can restart your device and boot up normally.

Step 2: Try booting the device in recovery mode

There’s an instance that the device is having a system crash, it occurs after a software updates or some of the system files are corrupted or damaged during the update process. If so, you can try clearing the system cache files, these are temporary files to help your device run smoothly like opening certain applications more faster. But, if one of these files are corrupted or damaged then it might cause some issues, like the screen flickering at random or auto shut off the device. Anyhow, here are the steps how to boot up in recovery mode:

  1. Turn off the phone.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge 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 wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

After the device done the process, you will then observe carefully if the device still has issues. If so, then you can try and proceed to the next step below.

Step 3: Master Reset your device to restore it to defaults.

If the issue still occurs after clearing the system cache, it could be a serious issue that you have to master your device. This is the last resort that you  have to do before bringing the device to a tech because they will still ask your permission to master reset your device if you haven’t done it yet. But, before you proceed you have to backup all the important files that was stored in your device and save to your SD card or external storage device. In this procedure, it will delete all the files and data in your device and restore it back to defaults, the same setting the first time you got your device.

Mostly, this is the solution of this issue but not guaranteed that you have the same issue with the others. So, here are the steps how to master reset your device:

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge 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.

If the problem still remained after the master reset and screen still flickering, it have to be a hardware issue and your device’s screen is needed to be replaced. You might have the same issue with our readers, just visit the nearest Samsung service center and bring the warranty with you if it’s still active. They might come up with a resolution and fix the issue.

Is it grey all the time when turn on the device? Have you tried changing it to other display rather than black and white? If it’s a no, then you should try to changing it to your liking. This feature is quite nice, you can choose what would appear if the screen is on sleep like the analog/digital clock, or an image. There are default colors also that you can choose, your device might be on  default  grey color. Here are the steps how to change your modify your Always on display feature:

How to fix your Samsung Galaxy S7 Edge that doesn’t turn on, other power-related issues [Troubleshooting Guide]

Power related issues are among the commonly reported problems as they occur without precedent and can be triggered by firmware and/or hardware issues regardless whether they’re simple or complex ones. The same is true even with the #Samsung Galaxy S7 Edge (#S7Edge), which is one of the most powerful smartphones available in the market today. Since we started supporting this device, we did receive quite a lot of complaints from our readers.

In this post, I will address a few of them–three, actually–and they’re among the most commonly reported power-related issues that often result to black/blank screen. If you’re recently bugged by an issue with your device and if it happens it has something to do with the power or characterized by a black screen, try to go over the problems I included here as one of them may provide you with an answer or solution to your own problem. To make it easier for you though, here’s the shortlist of the issues. Click on the link to jump to a specific problem.

For those who have other issues, however, make sure you drop by our Galaxy S7 Edge troubleshooting page as we’ve already addressed hundreds of issues with this device and majority of them were reported by our readers. You may be able to find solutions to your problem while browsing. However, if you need further assistance, you can contact us by filling up our Android issues questionnaire and provide us with important details of the problem.

Galaxy S7 Edge turned off while using an app, won’t turn back on

Problem: I was just using a couple of apps multitasking between Facebook and Messages when my Galaxy S7 Edge shut down or turned off on its own. I thought the battery got drained so I plugged in and left it for a couple of minutes but it didn’t charge at all. As a result, the phone won’t turn on no matter how many times I pressed the power key. I don’t know what to do as this is the first time this problem occurred. I need your help guys. Thanks.

Troubleshooting: It is possible that one of the apps you were using crashed and affected the general performance of your device that also resulted to a firmware crash. Consequently, your phone became unresponsive and won’t even respond even if the charger is plugged in. Things like this happen all the time and it may not be fixed unless you do something about it.

In this section, I will walk you through in addressing the problem. Let’s try to do some procedures and find out if we can fix it. Just follow the steps below:

Step 1: Try to force reboot your Galaxy S7 Edge

The force reboot procedure will simulate the virtual battery disconnect, which is equivalent to the battery pull procedure for devices with user-removable batteries. such procedure is very effective in fixing firmware crashes as well as minor firmware and hardware glitches. It must be the first thing you need to do; it is safe and very easy to do.

Just press and hold the Volume Down button and then press and hold the Power key. Keep both keys held down for 10 to 15 seconds. Provided your phone has enough battery to power up its components and that the problem is a minor system crash or a glitch, it should boot up successfully. Otherwise, the next procedure might tell more about the problem.

Step 2: Restart your device into the Safe mode

As the owner said, the problem occurred while he was using or multitasking between apps. Both Facebook and Messages are pre-installed apps and one of them might be the cause but we also need to consider that there are always other apps running in the background. Therefore, it is best that we try to isolate the problem first to determine if it’s the pre-installed or third-party apps that cause the problem. That being said, try to boot your device into Safe Mode.

  1. Press and hold the Power key.
  2. As soon as you can see the ‘Samsung Galaxy S7 EDGE’ 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 boots up successfully in safe mode, then at this point, we’ve already solved the problem as the phone powered up already. So, just reboot the phone to boot up normally. However, if the phone won’t boot up in safe mode or still returns to having a black screen after booting in safe mode, then you should go after the firmware.

Step 3: Attempt to boot your device in Recovery Mode

This procedure will power all the components of the phone but the Android user interface won’t be loaded.  In other words, it will be a lot easier for the phone to boot in this mode than in normal mode. If your device can boot up successfully into recovery mode, then there’s a chance you can fix it on your own without any help from a technician. Here’s how you do it.

  1. Turn off your Samsung Galaxy S7 Edge.
  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.
  3. When the Samsung Galaxy S7 Edge 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. 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.

If successful, you may proceed with the wiping of the cache partition and if that doesn’t help either, perform the factory reset.

As far as troubleshooting is concerned, this is as far as you can go. Anything beyond this point should be handled by a technician. I hope this helps.

Galaxy S7 Edge has an unresponsive black screen, not turning on

Problem: Phone was at 50 percent when I went to sleep. When i woke up it was dead. I plugged it in for a few minutes and tried to turn it on and nothing. I left it on the charger for another 30 minutes and still nothing. I’ve tried the master reset thing And nothing. Occasionally i can get the home screen to pop up that says samsung but it wont go any farther.

Troubleshooting: Fingerprint, accelerometer, gyro, proximity, compass, barometer, hear rate, SpO2 with a non-removable Li-Ion 3600 mAh battery covering a talk time up to 27h (3G) and a music play up to 74h. Indeed awesome features that resembles Samsung Galaxy S7 Edge. But how can you enjoy all these awesome features if you can’t use your phone. How can you experience awesomeness if you can’t simply turn it on?

We do have complaints on Samsung Galaxy S7 Edge that loses power. Then basically if it happens, all you have to do is recharge your device. What if after recharging, still there is no changes. What will you do? There is no room for you to panic because we are here to help you. We will giving you steps how to solve this problem. There would be three possible reasons why this problem occurs, namely: system issue, charger issue, battery life and hardware issue.

System Issue

A system crash is one of the common reasons why the device screen turns black and won’t respond. When the firmware stops working, the device will become unresponsive and all other services as well. This is the reason why the screen turns off and won’t turn back on no matter what you do. If this happens, mostly you will press the power key and nothing changes. You will recharge your device and still the same. So it is better to go ahead and force restart your Galaxy S7 Edge.

Press the power key and wait for 40 seconds or more to see if S7 Edge initiates auto reboot. If it doesn’t happen, you may press and hold the Volume Down button and the Power key at the same time for 7-8 seconds. It will vibrate, turn off and then reboot…hopefully.

Charging Issue

After performing a force restart if the device won’t turn on. Try recharging your device as this may be caused by a drained battery. The Samsung Galaxy S7 Edge slightly takes a longer time to recharge because it has larger capacity. It can be charged in three ways: wall charger, wireless and fast.

Wall Charger

  1. Connect USB Cable to Galaxy S7 Edge.
  2. Connect the other end of USB Cable to the wall charger.
  3. Plug the charger into electric socket and power on the charger.
  4. Wait till Galaxy S7 Edge is fully charged.
  5. Disconnect the USB cable from the Galaxy S7 Edge and power off the charger.

Wireless and Fast

  1. Power on wireless charger.
  2. Place the center of Galaxy S7 Edge back on the center of the wireless charger.
  3. Wait till Galaxy S7 Edge is fully charged.
  4. Remove Galaxy S7 Edge from the wireless charging pad.

(Note: 100% does NOT MEAN fully charged, 100% is just an estimation, wait until the LED light turns green.)

Firmware Issue

Try to see if the S7 Edge can boot in Recovery Mode. By doing this step, it will tell us whether the problem lies in the software or hardware. If the phone boots up in recovery mode it means that the problem is within the software. If it won’t, then it would be hardware. To boot in Recovery Mode, follow the steps in the first problem.

If the phone cannot boot up in Recovery mode, it would be better to visit the local Samsung Store to have the device checked by a Samsung technician or have it replaced, whatever applies.

Galaxy S7 Edge is powered up but the screen is blank

Problem: Hi, i have a Samsung Galaxy S7 Edge and a little problem. When i turn on my cellphone i can heard the open music and in the password area i can heard the keys sound when i touch the screen, but the problem is the screen,it still black. If you can help please send me an email. Thank you.

Troubleshooting: When you open your phone and nothing shows on the screen but you can hear the open music or even heard the keys sound. Most likely, this issue is referred to as black screen of death. It usually goes like this, you reboot your phone, you see the Samsung logo then it disappears. The screen goes black, the phone doesn’t respond. This is a sign that your device couldn’t load the operating system. This could be a hardware issue or a software issue. In order for us to know what’s the cause of the problem, let’s do these things first.
Step 1: See if you can fix it by force reboot

Press and hold the Volume Down and the Power keys together for 10 seconds and see if the phone reboots. It seems like there’s just some services that ceased to function and left the phone powered on with a dead screen. There were a lot of reports of problems like this and there were also owners who said they could even answer the call even if the screen is off. So, this step actually has a chance, a bigger chance, in fixing this problem. But if it fails, the next step might help.

Step 2: Try booting the phone into the Recovery Mode
So, your S7 Edge is still not booting up after doing the Forced Reboot procedure in step one. It could mean that there’s a more serious issue either in the firmware or the hardware. It’s easier to rule out the former so we’ll do that. As to the latter, we always have technicians to do some tests and fix the problem if necessary.

Now, going back to ruling out the firmware issue, try to follow these steps to try and boot the phone into the Recovery Mode:

  1. Turn off your Samsung Galaxy S7 Edge.
  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.
  3. When the Samsung Galaxy S7 Edge 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. 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.

If the phone refuses to boot up in this mode, then there’s nothing much you can do about the problem. Send the phone in for repair or bring it back to the store and let the technician do some tests to diagnose what the problem really is.
