Samsung Galaxy A31 touch issue

[Anirban A31]

Hlw Guys,

My Samsung Galaxy A31 has stopped working on landscape mode.

It's working properly on portrait mode and normal mode. But whenever I try to play any game or watch any YouTube videos it starts to have no response on the touch screen.

This incident happened recently after updating the new System Update

Plz Sir/Ma'am try to help us all having this type of problems.

Sorry for double-posting but I can't edit my post and the website keeps giving me an error.

But as an update to my post above, it now consistently starts happening between 5:00 - 5:30 AM. I wonder what system app triggers at these times automatically? Even if it is found, I doubt it could be disabled.

Updated to November 1 Security Patch, still happening.

Hello, can everyone please confirm that this is the same problem everyone is having? It's just a 3-minute video demonstration of my particular kind of issue.

YES!

This EXACT problem! It's started like a couple weeks ago. It used to come and go randomly, but now it's just staying there, no amount of restarting and rebooting is fixing it. This is driving me crazy.

same, after getting the Android 11 January Update it just never stopped happening where it used to come and go.

amazing.

I "might" have found a solution. Apparently there's a hidden touchscreen part firmware update menu that you can access, after I did this it kind of works but I have no idea if the bug will return sometime in the future. So if it's okay, help test it with me.

Open Phone app, dial *#2663#. A menu will automatically show up, tap TSP FW update (General) and let it finish. The problem instantly gets fixed, but I have no idea for how long.

UPDATE: Nevermind, started happening again a few days later. Doing the above just stops it from happening for a few minutes, but it comes back anyway because why wouldn't it.
