I9505 problem with screen sensitivity - Galaxy S 4 Q&A, Help & Troubleshooting

Just bought my S4 two days ago and I noticed screen sensitivity was awful in some games. I tested it playing Dead Trigger and Royal Revolt and I was forced to press multiple times in order for the screen to register one press. Touch was fine in any other apps or when performing different actions. After fiddling with the settings I activated enhanced screen sensitivity for glove use and now games work perfectly. Just wanted to know if anyone else encountered this problem with these or other games. I still don't know if games are poorly optimized, my phone's screen sucks or Samsung's bad touch sensitivity on all I9505.

Touchscreen Lag when playing games

So I noticed the other day that when I was playing NOVA HD on my 10.1 tab, sometimes the control stick would not move immediately when I moved my thumb. I thought it was a problem with NOVA but I just saw it happening again while playing Galaxy on Fire 2. The weird thing is that I can tell that the tablet is registering my touch because the stick lights up slightly to register movement, but it just doesn't move.
Has anyone else experienced this? Anybody know of a fix?
I have experienced lag of touchscreen in almost every graphical application. Just download e.g. writepad and try to draw something. This looks like a severe bug in touchscreen driver in the kernel. I would say that it looks like the touscr3n sampling frequency is too low

[Q] touch sensitivity too sensitive?

Hi All,
I have recently bought S4 and I'm having a small issue with it.
first of all, I turned off the "More Sensitive" feature in the setting, and "vibration on touch" is on.
However, I occasionally feel that touch is pressed before my finger actually touches the screen (the phone vibrates and types before I touch the screen when my finger is about 2~3mm apart from the screen), and it seems it's not consistent about it (some times it touches with 2~3mm gap and sometimes it doesn't).
I have even tried with the "display touch" from the developer mode and verified that it indeed touches with 2~3 gap...
The problem is...the ATT guy looked at me as if I'm overly sensitive about this...(the typical look of 'man this is just a phone')
Is anyone having this issue?

I have rarely noticed this myself, but usually only a 1mm-2mm gap for me, and maybe once every couple days. Really infrequent. On an older phone of mine, the cheaply-made car charger I was using caused my touchscreen to flip out and become super-sensitive. Might have been a static-to-ground issue or something weird.
Does it happen when you have it plugged in only, or does it happen while disconnected?
Also, speaking on static electricity, is it dry in your area? Do you have problems shocking things?
*shrug* only some suggestions. Could be a miscalibrated or otherwise defective touchscreen...
Mine also does this, whether plugged in or not it does it.
Nor do I have a problem with static in my house.
My best guess would be the air view sensor is falsly detecting the small distance away as an actual touch.

touchscreen issues with 2 games found

This is very odd behavour and I'm wondering if it's the games themselves or not.
Dungeon Hunter 4: When in the World Map screen, a small area near the lower right corner of the screen is completely unresponsive and won't scroll the map around nor respond to any touch at all.
Ravensword 2 Shadowlands: This happens on and off but it also happens in the same area of the screen as the other game. The attack button stops responding sometimes. This one is harder to pin down because it doesn't happen all the time.
I installed a multi touch screen testing app and it shows all areas of the screen working fine though. Has anyone noticed similar behavior with either of these 2 games? I wish I had another N7 to install them on to test so I could determine whether it's the games themselves or whether my unit's touch sensors are funky in that spot with certain games.
I have the same issue with the lower right in GTA Vice City. I'll be driving and go to hit the break and nothing happens. Really annoying!
I discovered it was the games causing it, not the tablet's fault.

You may read my topic, my touch screen sometimes stops respondind too. http://forum.xda-developers.com/showthread.php?p=44601701#post44601701
i think the problem not in games..
For now i have only 1 question: is it hardware or software problem...?
It's the tablet, not the games.
Swipes and taps sometimes do not register on Candy Crush Saga and Bingo Blitz. Returned mine for good until they sort this out.

Touch screen sensitivity adjustment missing

Has anyone found a way to adjust the touch sensitivity of the screen like on the older models. You used to be able to adjust it very sensitive to work with gloves. It seems that this screen is a little less sensitive than the S7. I find myself having to double tap a lot of things. Is it there and I am just missing it?
Good Question...but no reply yet
Yes mine is also not sensetive enough, i also have s8 plus and its much more sensetive
S8+ touch sensitivity issue
I am having an S8+ and facing the same sensitivity issue. It's very slow to respond and most of the times take more than one tap to respond. And there are no adjustments found!!

Up. Having the same issue on my S8.
Yeah sometimes I have to tap apps 3-4 times to get them to launch.
Do you all have screen protectors? I have one but I don't want to remove it cause I paid a lot for it.
I also have weak touch sensitivity on my Galaxy S8, I have to tap several times on a certain app to open it, so frustrating, will probably return my device! :/
My S8+ is over sensitive...
Is there any fix for this +
Same issues on my S8. Most time i must push 2 or 3 time to open a app.

Multi touch issue s8

Hello all
I just got a UK unlocked s8 and I love it but I'm having an issue with the multi touch.
It cannot register multi touch properly. I notice the issue whilst typing on the keyboard.
I downloaded those multi touch tester and if I put my left thumb and 2 fingers from my right hand then place them on the screen at the same time, it does not always register 3 touches. If you move your fingers then it will.
Anyone have this issue?
Could it be another app that is causing the issue?
Faulty screen?
Thanks
Okay so I've worked it out. The issue occurs when I set the phone to qhd! If I use full HD then the issue goes away. How lame is that!
Edit. I've set qhd again and this time it appears to be working. I'll monitor this
I got 10 touch registered with no problem, before running out of fingers and screen is set for maximum resolution, never noticed any missing touches either. Not sure why yours would be different.
Well I guess me changing the resolution messed something up. Changing them back and forth sorted the issue out
I was having the same problem with my galaxy s8 plus. It couldn't recognize more than 2 fingers. At last I got a solution. That is, just go to your call dailer and then ty-pe *#2663# then update TSP. And you are ready to rock 10 fingers.
same problem

I have the same problem. Whenever i play a FPS game using 4 fingers it only allows me to use 2 fingers. Rebooting the phone only temporarily solves the problem before it comes back. Changing the resolution solves it temporarily as well. Is there any other solutions?
