Why does my A55 not register touches very well?

[Melaphanite]

My A55 jitters whenever i use two fingers to play a game with a screen protector. The fix was to remove it, but i do play CODM and i do use finger sleeves. And if it isnt pure skin in contact it just doesnt function as well. Like it jitters and stuff. 

i wonder why this is.

The interference is likely is due to the screen protector, especially if it came from a third-party manufacturer. Touch screens work via conduction - if a surface is blocking the screen, it might not register touch immediately. 

Try taking off the screen protector, or use an official screen protector installed at a Samsung Service Center instead. 

Thanks very much, and have a great day.

I already took of the screen protector. But i'm just wondering why the screen is so insensitive even when im wearing thin finger sleeves.

Have you tried increase sensitivity on display settings?

Yes, it is on

I actually mentioned a tip with someone else having the same issue, one trick that I do that increases the chances of a sure scan is to register your preferred finger twice.

So for me

2 - right thumb
2 - left thumb
1 - index finger

That increases the chances of unlocking the device faster and more accurately

That isnt what im asking about?
