Samsung Galaxy S6 Edge Plus screen not working after dropping

Problem: I dropped my phone (Samsung Galaxy S6 Edge Plus) last night (not in water and for the first time ever) and the screen immediately started flickering and then went black.  I rebooted it and it was fine for a few minutes but started flickering again and then went black and wouldn’t come back on.  I charged it and it came back but has been doing this on and off ever since.  Can this be fixed or do I need to just get a new phone?

Solution: In my point of view, it’s obviously a screen problem when you accidentally drop the device but, you can try troubleshooting it if the problem is caused by a software issue. We recommend booting your device to Safe mode first, to determine if it’s caused by a third-party app.

Boot up in Safe mode and remove suspected apps

Now, the purpose of performing this procedure is to make sure that your device is not experiencing any software issue caused by a third-party apps. This is a diagnostic mode that temporarily disable all third-party app and run only the pre-installed, most basic tools are possible to use like sending and receiving text messages and making and answering incoming calls. If your device screen won’t flicker while in this mode, then we are confident that it’s an app causes the issue. Below are the steps how to boot in Safe mode:

  1. Press and hold Power key and Volume down key together until the Samsung Galaxy S6 Edge Plus logo appears.
  2. Quickly release the Power key button but continue holding down the Volume down key
  3. Release the Volume down key if the ‘Safe mode’ appears at the lower left of the screen
  4. Test your device and observe carefully if the device screen still flickers.

If no issue occurs while in this mode, then we recommend to start removing the suspected app. It depends on you how or what app you’re going to remove. If you haven’t tried uninstalling apps before, follow these steps on how to do it:

  1. Go to Settings
  2. Tap Applications
  3. Tap Applications manager
  4. Make sure that you’re inside ‘ALL’ tab, just swipe left or right to navigate through options
  5. Locate the suspected apps, then tap it. NOTE: You can uninstall as many apps as you like
  6. Tap Clear Cache
  7. Tap Clear Data
  8. Go back to Home screen

First off, the purpose of clearing the cache and data is to avoid future issues (error messages, lag issues, etc.) that could give more problems to your device. There’s an instance that uninstalling an app directly might leave some files and rarely causes an issue, it’s better to be safe.

Now, after removing the suspected app, make sure that you observe your device to determine if the screen still flickers.If so, then proceed to the next steps.

Boot in Recovery mode and clear System cache Partition

Similar to Safe mode, this is also a diagnostic mode that will determine if your device will respond using the hardware buttons and other essential components are still working. Here, you can choose from different options, like updating your softwares and other wipe functions, to recover your device and boots up normally. Here’s the easy steps how to boot up in Recovery mode:

  1. Make sure that your Samsung Galaxy S6 Edge Plus  is turned off
  2. Press and hold Power key + Home key + Volume Up key together
  3. Continue holding until the Android mascot appears, then release all keys

In case your device successfully boots up in this mode, we recommend to proceed and wipe the system cache partition. The system cache are temporary files frequently used by the system, clearing it will force the system to create a new one. Actually, in some cases after updating the system software, it can damage or corrupt these files and cause an issue but, it’s rarely to happen. But, just to be safe, it’s better to manually clear it. Don’t worry it’s reset your device.

  1. Navigate using Volume keys and highlight the ‘wipe cache partition’. Press Power key to confirm selection
  2. A message will appear that the process started and finished.
  3. Once done, highlight ‘Reboot system no’ option. Press Power key to confirm.
  4. The restart will take longer than the usual restart. So be patient.

Again, normally use your device and observe if the screen still flickering. If so, then proceed to next procedure below.

Master Reset your Device

Now, this procedure is optional. But, we recommend to start making backups to all important files and save to either your PC or flash drive. It will basically clear all data saved in your device storage and restore it back to default. Otherwise, you can bring your device directly to a tech to determine their findings of the issue. If it is a hardware issue, then most likely they will advise you to change the device screen or they might suggest changing it with a new unit, but it depends.

To backup your important files, you can plug your device to your PC and run the Syncios data transfer. Make sure that the debugging mode is turned on, if you don’t know how to turn it on, then follow the steps below.

  1. Go to Settings
  2. Tap About Phone
  3. Swipe down and locate ‘Build number’, then tap it 7 to 15 times until a message appears ‘Developer mode has been turned on’
  4. Tap back button to go back to Settings menu
  5. Tap Developer options
  6. Tap Allow USB Debugger, then tap OK

Once done, you will be able to see the primary of window of Syncios data transfer and follow the procedures. You can as well go to Settings > Backup and reset > Backup my data > Auto backup > Back up now.

Then proceed and master reset your device, follow these steps:

  1. Turn off your Samsung Galaxy S6 Edge Plus
  2. Press and hold Power key + Home key + Volume Up key together
  3. Continue holding until the Samsung Galaxy S6 Edge plus appears, then release all keys
  4. Navigate using Volume keys and highlight ‘wipe data / factory reset’ option. Press Power key to confirm.
  5. Select ‘Yes — delete all user data’ then press Power key to confirm
  6. Once done, select ‘Reboot system now’

Bring the device to the nearest service center

If all procedures fail and the issue still remained, then it is a hardware issue. It could be the screen has the problem and it should be replaced and only the professionals are able to do it.
