One UI 8.0 and Galaxy Tab S8 Plus - Multi-touch breaks

Sharing for others who might be impacted & looking for the fix..

One UI 8.0 recently updated onto my tablet - an S8 Plus. After that happened, the multi-touch stopped working - tapping 3 or 4 fingers on the screen caused the active app to think I was trying to zoom in/out, or it would jitter around, or just nothing. Thought maybe it was a bad screen protector, or my case magnets had started to affect the tablet, but replacing the screen protector did nothing, and then I noticed multi-touch would start working again if I did a force restart, until... screen lock and unlocking via fingerprint. Then no more multi-touch again.

Turns out the fingerprint scanner is messing with the touch recognition. The fix (at least until Samsung fixes it) is to go to Setting / Lock screen / Screen lock and biometrics / Fingerprints and just turn off the Fingerprint unlock setting. (don't remove your fingerprints from the device, that was an unnecessary step that was suggested to me by AI, and it makes you have to re-enable biometrics for all the apps you used it for)

Yes, you need to unlock the screen with a PIN going forward instead of fingerprints, but multi-touch will stay perfect; and apps can still use fingerprints to unlock if you choose.

I've submitted a bug report through the members app (I think, I hope it went through) - kind of hoping it's impacting enough people that it gets fixed (and soon)

Hi MikeS3,

We sincerely apologize for the inconvenience you’ve experienced following the recent One UI 8.0 update on your Galaxy Tab S8 Plus. We understand how important smooth multi‑touch functionality is for your daily use, and we regret that this issue has disrupted your experience.

We recommend the following troubleshooting steps helps to restore proper functionality:

Navigate to Settings > Lock screen > Screen lock and biometrics > Fingerprints
Toggle Fingerprint unlock off
- Note: You do not need to delete your saved fingerprints. Apps that use fingerprint authentication will continue to function.
Unlock your device using your PIN, password, or pattern instead.
Restart your device after disabling fingerprint unlock to ensure settings are applied correctly.
Check for software updates regularly under Settings > Software update > Download and install, as future patches may resolve this issue.
Clear system cache partition (via Recovery Mode) to remove residual data that may affect touch performance.
Test without accessories (screen protectors, magnetic cases) to rule out external interference.

We have logged this issue with our development team and are actively investigating a resolution. Your bug report submission through the Samsung Members app is extremely valuable in helping us prioritize and address this matter quickly.

We truly appreciate your patience and understanding. Please rest assured that restoring full multi‑touch functionality is a priority, and updates will be rolled out as soon as a fix is available.

What an useless troubleshoot steps as smasumg knows that only fix is to fix thier One Ui 8 instead giving time wasting troubleshooting steps which even after following not working and has to choose either multi touch or biometrics.
