Multi touch problem

[warrior13]

I have an s8 plus for 2 years. Recently my multi touch isnt working and it detects only 2 fingers at a time only and that too not perfectly. I realized that while gaming which requires more than 2 fingers to use. I used a third party app and checked how many fingers were registering at a time and only 2 were. 

Please help because I wont be able to afford another mobile and theres no solution anywhere. Thanks

You can search for each in settings search bar.

all of them are switched off

I have found two solutions, one should work:
1- Reduce your screen resolution in Settings > Display > Screen resolution.
2- Go to your phone dialer and type *#2663# then update TSP, check the attached screenshots.
Let me know if any of solution works.

I dialed that code, nothing happens

I've done both. made no effect

Did you tried on HD+ resolution? try to increase and decrease the resolution.

[warrior13]

I tried that. still the same

This issue can be caused by a bug in the game that you are playing.
I've just downloaded a game called Magic Piano from play store to try 3 finger touch 😅
You can download the same game to try out your multi touch.
Let me know.
