Tab s4 touch to sensitive - Samsung Galaxy Tab S4 Questions & Answers

Hi everyone. I have a problem with my tab s4 touch sensitivity. When playng pubg and when i try to aim without scope the display is too sensitive, when aming the pointer moves almost half a centimetre even with the slight movement of the finger, it jumps all the time and aming without a scope is almost impossible, is there any way to reduce the screen sensitivity? Thanks

Screen problem

My screen makes sort of a cracking sound only in the lower right corner when touched. Is this normal behaviour of the resistive screen or is it a problem with the screen itself, needing repairment? The device is 10 days old.

[q] xperia zl screen unresponsive during gameplay

Hi everyone. I had a Xperia z but sold it and got the smaller Xperia zl because of personal preference. However I have noticed a few potential flaws with this phone . First of all the back of the phone gets pretty hot whenever I play games Like Real Racing 3 etc, it has even shut itself off on one occasion.
My main issue with the phone is That the touchscreen is pretty unresponsive during gameplay. The screen is very responsive during normal usage, for example navigating the home screen or browsing the web, The phone is able to register even the slightest of touches. But during gameplay I have to tap on the screen with extra force to steer in Real Racing 3 or whenever I am playing games via the Drastic DS emulator, the on screen directional pads dont register my taps upless i tap pretty hard or press the buttons with a slight swiping motion. i am worried because I got this phone for gaming and really don't want to get rid of it. Could it be the screen protector thats installed? or that the touch screen isn't calibrated?
also sometimes when i try to navigate between home pages by swiping, the screen bounces back instead of going to its intended target. i have the model c6506. and its on android 4.2.2 and also i never had any such issues with the xperia z
maybe its the screen protector. other possibility is that its the games' problem, not the phone. as u say, its good when on home screen etc.
iam inclined towards second possibility though, its the game which is problematic.
hit thanks if i helped u!

Ok i downloaded super stick golf 2 and tried it and guess what, the touch screen is very responsive, that game uses mostly taps, and this registers the slightest taps. I am gonna test some more games and see if your theory is right.
ok tested some more games
Tested simpsons tapout and had the same issue with taps not being registered properly
Tested Dead Trigger and the game runs flawlessly, the slightest taps were registered
Tested Beach Buggy Blitz and the screen is slightly unresponsive also, kinda difficult to steer, i have to apply extra pressure to the touch screen.
Ultimate Mortal Kombat works flawlessly, i was pulling off combos and brutalities with ease
Jetpack Joyride was a bit unresponsive also
So I guess the problem varies from app to app. I really dont want to remove the screen protector but i have to to ensure that I dont have a faulty device. I have an extra screen protector so as soon as I can verify that its the screen protector, i will simply re-install it. now how do i go about removing it because i am trying but it seems glued on!
gonna sell this

OK its definitely not the phones touch screen, i just did some tests and the touchscreen is absolutely responsive in every aspect of the operating system except when playing some games. So the digitizer is great. so it must be the darn screen protector!, and i dont want to remove it because it is glued on and i dont want to risk damaging the screen underneath. my favourite games are the ones giving problems with responsiveness. Even the ppsspp emulator from the playstore i gotta swipe the directional pads etc for the game to respond.
I dont think screen protector was the culprit, the app itself is not optimize for sony device or sony OS is not that stable.

as per my understanding, ur screen is flawless, its the apps, maybe they are not optimised.
more tests done
ok I can confirm its definitely the apps, some of them are are optimized properly for the xperia zl. I have tested need for speed most wanted (2012) and it works flawlessly, controls are spot on and screen very responsive. Also raven sword 2 and pvz works great. its a minor issue at best really but i cant play my psp or nds games on my zl properly unless i use a controller. which is fine cause i do have a huge 5 inch 1080p display. and I really love this phone so i will overlook this issue. for now

[Q] M8 Touchscreen Latency

Hi Guys,
Recently reverted back to Android from iOS. I have had low end and mid range Android devices for development purposes as well as a Windows Phone devices all the way through.
Since taking up the HTC M8 as my day to day device, I have been noticing issues (teeth grindingly frustrating issues) regarding touch screen accuracy and responsiveness.
A prime example of this is when using a browser (Any browser, on both GPE and Sense editions). When making a pinch to zoom gestures, my fingers can move almost half an inch apart before the actual zoom process begins. I have tested this on a Samsung GS4 and found this not to be the case on that device. I believe the root cause of this problem is also behind the poor accuracy when typing on *any* keyboard (i find myself re-writing words again and again despite the larger screen size, you'd expect larger on screen keys would equal less frequent miss stokes...). Again this is not the case on the GS4.
I have used a multitouch testing tool to gauge some measure of response time and touch latency. I have found when moving points at any rate of velocity they begin to lag quite substantially behind my finger. I don't know if this is part of the same problem.
I am wondering if anyone could shed light on whether this is an issue with display touch sensitivity settings, something which could be changed at the kernel level or a limitation with the hardware itself,
Is it also possible that the same algorithm used to detect and handle touch for devices with smaller screen real estate is still being used and that the distances and tolerances for touch and gesture recognition are acting proportionally to the screen size.
Hopefully this is something we can fix, it makes the device tiresome to type with and feel clunky and unresponsive.
The screen on this phone has a higher touch response then the iPhone

Go in a store and check out another phone. If yours turns out to be defective (which should be the case), you should get it replaced

No issues with mine.it's better than iPhone5s I had. Which had some issues sensing touch on corners of display

If you have just moved from the iPhone, then this is a slight orientation problem ... and actually the M8 is the nearest you can get in terms of responsiveness to an iPhone, thanks to the fastest screen response time on the market ... for keyboard, you need to deliberately slow your finger speed down for few days and then you get used to it ... Screen/phone size also play a part in your typing because your mind can remember sub-consciously how much finger movement to do for typing ..
All the above is assuming you were an avid typist for long time on an iPhone

Thanks for all the replies, it is likely that its a transitional issue alright. But before i write it off as such, can anyone verify the issues regarding pinch to zoom? Just trying to figure out if it is a faulty device i have on my hands or not
I get the exactly the same issues. I really thought it was me .
However I had the HTC One M7 and had no issue whatsoever.
LG G2 also same no issues .But since getting
HTC One M8, the touch accuracy is well absolutely useless. I am forever correcting what I type.
I don't think its the hardware but something to do with the Algorithm..No matter what keyboard you use or calibration you do. doesn't make any difference
I am hoping that lollipop cures this problem..
My touch accuracy has always been great. I'd say that if yours isn't it's a hardware problem.

I tried the m8 and iphone 6 instore and compared them. The m8 screen is very sensitive, requiring minimal touch to be activated. This may be why tests are showing that the m8 has a faster touch response. However, when dragging your finger along the screen, such as swiping launcher screens, the iphone is more responsive.
I then tested "show touches" on the m8, the touch lags behind my finger.

Samsung's High touch sensitivity on OnePlus3.

Can you increase the touchscreen sensitivity so that u can use any object (preferably a pen) to write/draw on the screen. I know Samsung Galaxy have this option, so that you can use it with gloves, but any pen works on it too.
Thanks.​

Touch panel responsiveness

Hello,
I'm using my Pixel 3 XL for almost 3 months and I facing one thing that is super annoying. Everytime when I'm playing games I'm covering the side of the screen around the notch (just a bit with the palm) and touch panel becoming less responsiveness than normally. Is it normal thing? Does everyone facing the same thing?
