Hi,
I’m experiencing touch screen issues on my Samsung Galaxy S9+ that make my phone unusable at times (screen reacts without input, opens and closes windows, sends stuff, etc - ghost touch).
I’m looking for fixes, so if anyone has any ideas what I could try, I would be really greatful!
I’ve read that it might be helpful to upgrade to a newer android version. Currenty it’s android 10 on my phone, the automatic installer doesn’t show me a newer one (/e/ OS 1.14-20230815320612).
Is there a way to get a newer android version?
Unfortunatelly I don’t have TWRP installed yet and have no easy version to unlock root access on my phone.
Thanks for your help, and I hope my post is in a category that makes sense, if not you can totally move it or tell me!

Flashing the new ROM could be done by adb sideload, As for recovery, this can be done equally with TWRP or the Recovery-e.
If you don’t want to use adb sideload from your PC you can investigate the ability of your Recovery to install from a location like (the root of) SD card or external USB storage device and copy the new ROM to such location and use Install from Recovery.
