Fixing ghost touch - how to upgrade to newer android version

[ja.k]

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!
Jacky

Your partial version string seems to find a match with a stable build listed here https://images.ecloud.global/stable/star2lte/. Perhaps you could confirm if you need more support.

If stable you might have expected an OTA Upgrade to Android R,

but it hasn't happened for you

What OS OTA upgrade means click here

Usually for /e/OS ROMs to upgrade the OS you have to do the following

• If available download the correct OS build from the supported device list
• For some devices you also need to download the stock ROM from the vendor site.
• Take a back up of your data
• First install the Stock ROM
• Next install the /e/OS ROM. Here you can take help of the install guides available on our documentation site.
• If required apply the backups you downloaded before starting the whole process

An alternate to this tedious process is where we offer the user the option to upgrade the OS OTA. This option is available for stable device builds only.
This process is easy for the user but requires a lot of development and testing effort.

Different /e/OS build types

Completed

• Gigaset: GS290 : Q (A10)→ Android 11 (R)
• Oneplus: avicii : A12
• OnePlus : avicii : Q ( A10) → R (A11)
• Fairphone: FP4 : R ( A11) → S (A12)
• Fairphone:FP3 : R (A11) → S (A12)
• Fairphone:FP3 : Q (A10) → R (A11)
• Samsung: s7 / s7+ : Nougat (A7) → Q (A10)

• Teracube: 2e / zirconia: Q (A10) to R (A11)
• Teracube: emerald & zirconia : R (A11) to S (A12)
• Samsung: S7 ‘herolte’ ‘hero2lte’: Q ( A10) → R (A11)
• Google Pixel ‘redfin’: S(A12) → T(A13)
• Gigaset: GS290: R(A11) → S (A12)
  • All OTA OS upgrades are on stable builds

Testing

You would need a good backup; you could consider doing the upgrade as if a new install as https://doc.e.foundation/devices/star2lte/install. Moving from Q → R you would need to Format data.

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.

Another option would be to change from stable to dev https://images.ecloud.global/dev/star2lte/ where Android 13 (T) is available.

no easy version to unlock root access on my phone.

I am not sure I follow but to make an fresh install you would first Enable USB Debugging.
