I've been using my s9 plus for past a year and it was all good so far .but now I'm started experiencing a problem with the screen. When I turn the screen off and turn on immediately, the display flickers and a color change is there and when I keep screen off for 5 sec or more and then turn on. My display is normal and when using, there is no issue at all. The only issue is when screen off and turn on immediately..
Does anybody experienced this before ? Or am I the first to have this weird....
Feel like moving out of Samsung now
First : Update as been delivered in some Country, check yours
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.
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.
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:
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:
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:
If the problem continues after this, bring your phone back to the store and have it checked
I'm also facing the same issue on my samsung s9. I did all the way to fix it but it doesn't work still not yet resolved. When I try with recovery mode then I'm unable view all options. Really disappointed.
Yes, I also suffer from the same thing. It has happeed since two weeks ago.. it flickers when i turn off and turn on the display immediately. but if i leave it for some time, it is normal. when it is normal, it is normal. but it is really annoying and dissapointing. thinking to change to apple maybe
