I use to think that it was bad luck that my S9 plus have all flickering but now that i read all this is unbelievable that a prestige brand  like SAMSUMG  is not doing anything about it, my S9 begin with all the flickering and screen problems with last update  is was randomly but then get worse  at the point the cellphone is unusable, I  want to belive that SAMSUNG  have a solution for the  problem  they last patch did.

Can anyone please confirm if Samsung have released an update or fix for this issue as my wife's phone is now experiencing these issues.

We have tried all known fix methods NONE of which have worked.

 

Any help or advise would be much appreciated from members or SAMSUNG themselves.

My issue was fixed after the last software update...I'm not sure if it's still an issue on the s9 and s9 plus as I have not got the s10 plus...but I did try everything when I did have the phone..maybe worth chatting to samsung on samsung chat or giving them a call if your not happy with it and the phones under warranty

I am experiencing the same problem. Iain what version of software, specific model of S9 you are using. I received October update at SM-G9600/DS but the issue didn't resolve. It's been quite a few months passed. Don't know why Samsung is not paying attention to this serious problem?

Force restart your Galaxy S9

Always begin your troubleshooting with a reboot because while it’s a very simple procedure, it’s also very effective in dealing with problems that are not really that serious or complicated. A flickering screen might be a sign of one of those problems. However, instead of doing the normal reboot sequence, I suggest you do the Forced Reboot to simulate battery disconnect and refresh your phone’s memory.

  • Press and hold the Volume Down button and the Power key together for 10 seconds or more.

Your Galaxy S9 will reboot like it usually does and if the flickering issue stops, then the problem wasn’t really that serious. There might have been some glitches in the system or some app may have caused it. But if it continues, then move on to the next procedure.

Reboot your phone in Safe mode

Rebooting your Galaxy S9 in Safe mode won’t fix the problem but it will tell you right off the bat if it’s caused by an app. When in this mode, all the third-party apps are temporarily disabled. So, if one of them is causing the problem, the flickering shouldn’t occur while the phone is in this mode.

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the screen.
  3. When SAMSUNG appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

Once the phone enters safe mode, continue to observe it to know if the flickering occurs from time to time or not because if the problem seems fixed, it means there’s an app that causes it. The next thing you should do is find that app and then uninstall it:

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > Apps.
  3. Tap the desired application in the default list.
  4. To display preinstalled apps, tap Menu Show system apps.
  5. Tap UNINSTALL > OK.

However, if the flickering continues, then you should move on to the next procedure.

Delete all system caches so they’ll be replaced

The Android system creates caches for all services, features and apps so there should be a cache for the service that handles the operation of the display and touchscreen. However, you don’t have access to those apps but you can delete them all at once. Once the deleted, the system will recreate them during the first boot sequence after wiping the cache partition and all of it is done automatically so you don’t have to worry too much about it. So, to delete those files, follow these steps:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Android logo displays, release all three keys.
  4. An ‘Installing system update’ message will show for 30 – 60 seconds before the Android system recovery menu options appear.
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.
  9. Press the Power key to restart the device.

After this, try to see if the flickering continues because if so, there’s one more thing you should do before you actually bring the phone to the shop for a checkup.

Perform the Master Reset

A reset will rule out the possibility that the screen flickering problem with your phone is due to a firmware issue that’s why it’s necessary to do this. Aside from that, all your personal information will be deleted so your privacy is protected. But bear in mind that all your files and data will also be deleted especially ones that are stored in your phone’s internal storage, so make a backup of files you don’t want to lose. After the backup, remove your google account from your phone so won’t get locked out after the reset. Once everything is set and ready, follow these steps to reset your phone:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

If the problem continues after this, bring your phone back to the store and have it checked
