There was an old bug similar it only occured when low quality power bricks were used. If you play while plugged in try playing not plugged in.
It changes nothing at all I already play plug and without plugging anything changes
What version of software are you running and I'd factory reset the tablet it might clear up a bad update or something
SHIELD TABLET K1 6.0.1
And i don't know but in the video he has got the same problem of me

Hello, I have an issue with the touchscreen of my nvidia shield tablet.
I bought the tablet only one week ago and I'm on the Stock lollipop version 5.0.1 (2.2), but I had the same issue with the KitKat version.
When I hold my finger on the screen and I change direction, the shield take a long time (about 1 second) before validate this change of direction.
This issue make all my games unplayable in touch mode. (If I use a controller, this problem doesn't exist)
I wanted to post a video to show the problem but I can't because I'm a new user. (I can pm the link if necesserary)
On this video I activated, in the developer mode, the trace of the movement to see that the lines moves very late after my finger. (I'm doing the same test with LG G Pad to compare and see that it respond perfectly)
In the Real Racing Game: I move my finger with very little fast movements and the wheels doesn't move at all.
I tried the calibration tool in lollipop but the problem persists.
I tried also a Custom Rom ([ROM][4.4.2][wx_na_do] AOSP for Nvidia Shield Tablet LTE US)
My questions:
- Does every Nvidia Tablet Shield have this problem or is it only mine?
- Is there a way to configure the pressure and move sensitivity (from the config file /system/usr/idc/touch.idc)
I would like to know if someone has the same issue to know if I have to send back my tablet in warranty.
Thanks in advance for your time.
I've had this issue, but only while charging. More noticeably while charging using 3rd party chargers, though the nvidia charger does have some "lag" as well.

Thanks you for your answer.
I have always this problem, I never tried when the tablet is charging.
In fact the touchscreen is relatively responsive when I touch and release quickly.
The problem is when I let the finger on the touchscreen and I change the direction slowly with small moves.
Hello,
I re-up this post because I really need your help.
I sent back my tablet to the seller for my touchscreen issue.
But they don't undertsand and tell that there is no problem with the touchscreen.
They compared to another Nvidia shield and told me that the response is the same than mine.
I can't believe that all the Nvidia shield has the same response because for me all the games are unplayable.
So I would like to know if someone has the same feeling (delay) about the touchscreen when you slide and change laterally the direction with your finger to play games like racing or platform games.
Thanks in advance
Sorry if I open this again.
I've been going crazy with this issue too and have been looking around for a fix, too.
I tried applying different configurations to my /system/usr/idc/touch.idc file, without any noticeable differences.
The only setting that works for sure is 'touch.size.calibration': the possible values are "none | geometric | diameter | area | default". Whatever I set besides 'none' will make the touchscreen work like a touch pad (you scroll around and there's a little cursor moving, you tap and it taps on the cursor's location).
I'm not sure which setting (if any) can calibrate the touchscreen for small movements. The documentation is a little unclear (I only found this: https://source.android.com/devices/input/touch-devices.html ).
Does anyone know more about this configuration file? I believe it's a common issue for all the shield tablets, it would be great if we were able to fix this.
Please note that root is required to edit that file, of course. Plus, the /system partition needs to be writable (mount -o rw,remount /system).
Same issue on new k1
Same issue on K1
I purchased an new K1 today and am experiencing the same issue. After enabling "show touches" in developer options it is very clear that the display periodically becomes unresponsive. I have also tried to re-calibrate the display with the Sensor Calibration Utility with no change. This happens while NOT connected to a power supply. So, I'm not sure what else to try.
What have others done about this issue? Do you return the device to the reseller? Because as it is, I can't play most games and find a typical browsing experience annoying.
Thanks in advance for any advice.
After trying everything, including full wipe, different Rom etc, I have returned it to the reseller. I got another one and and am very happy with it. Turning screen off and back on gets the responsiveness back for a while. Good luck with swapping it for new one, reseller I dealt with made no issue of it.As I have restored tablet to factory settings,I have just shown a video of a tablet going all crazy to a guy at the counter, and he gave me a new one.

Thanks. I appreciate you sharing your experience on this. I got it from Amazon, so I hope they are cool with it.
Hello. I have an Nvidia Shield tablet k1 on lollipop 5.1.1. Everything is great about this tablet except the touch screen. It is really sensitive. Also, when I am scrolling, it "jumps" and goes faster than I actually scrolled. It scrolls faster than it should. I found this thread on xda. It helped a little with the being too sensitive issue, but scrolling is still really weird. This is my second device since the first one's micro sd card was defective. They both are like this. Is there anything I can do, or do I just have to deal with it?

I was opening a thread with this exact same issue. I'm not on stock though (using the latest CM12 nightly), so I don't seem to have the 'Sensor Calibration' option.
Also the touchscreen seems to register a touch even when the finger is not touching the screen.
On the other hand, if I scroll a very small distance (like 0.5 centimetres) the list I'm scrolling doesn't move at all. This doesn't happen on other devices such as my Nexus 5 and Nexus 7 and is very annoying in some cases (some games, or moving the cursor for keyboard input).
I'll try to record a video of this behaviour.
What can we do to fix this?
Update: found a video (not mine) showing the issue I'm talking about: https://www.youtube.com/watch?v=08uPtusOJHQ
anyone else with this issue?
I also have this issue on/off sporadically on stock rom.
I'll be scrolling and itll jump back the opposite direction
Its like it looses track of the touch then catches it again.
It's irritating as my S5, Nexus 2012 have no problems scrolling smoothly.
I don't recall the original shield i tested in store to have this issue either.
Currently having amazon ship me a replacement to see if its just limited to the one I received. (QA issues)
Calibrating screen might fix the issues: go to About in settings and tap on model number until the calibration screen comes up. then hit calibrate. don't touch the screen then when it asks to reboot, reboot.

Did it fix the issue I posted the video about? I'm on Cyanogenmod now so I don't have the option to calibrate the screen, but I would consider going back to stock if it fixed this issue...
Calibration doesnt help at all , same issue at brand new k1. Nvidia says thats normal functionality lol
Yeah, very normal for a gaming tablet which would require precision...
Not trying to take up for this thing but I haven't had the first touch screen issue with it . so maybe not all is affected?? I've tried to replicate the issue but just can't everywhere I touch and slide is smooth
You mean it doesn't "jump" like the OP said? I don't seem to have that issue either.
I'm more concerned about the touchscreen's precision, as shown in the video.
Hello!
I'm having a weird problem after updating my Xperia Z3 (C6643 brazilian variant - Single SIM) to Sony's Official 6.0.1 - 23.5.A.0.575.
When I am playing a game, sometimes the game kinda "exits" immersive mode showing top notification bar for an short instant and then coming back to immersive. This is causing some of my games to Pause and its really annoying me! Is anybody facing the same issue?
I noticed that this Issue is not only related with games, but also affects other things, for example, when I am texting in whatsapp the keyboard randomly closes as if I had "touched outside the keyboard". I don't know if this is related to the same bug, but my guess is yes.
[edit]
I found out that the problem is not only related with games but with any app. For instance, when I am watching YouTube the video keeps randomly pausing even if it's already loaded (not an stream problem)
And somehow the problem is related to wifi, when I turn off wifi and play some games the issue disappears. But when I turn on wifi the issue occours.
Can anybody help me?
I'm really sad because I loved marshmallow but this bug is really annoying to me..
Thank you!
Regards,
I'm facing simular issues. But I've noticed on a different app, the screen recognizes touches where there isn't any. But not only with WiFi, even with WiFi turned off it does it.
Also, it gets really bad when charging! That's probably why everything pauses on your device. Because it recognized touches where there aren't any!
This bug turned up on my phone on the 570 update and still exists on the 575 version
i know this question is kinda old but i am xperiencing the same issue with my d6653 will try to downgrade tonight to know if it has affected the unit. One techincian here in the Philippines associates the random touches with the heating issue that some units experience. May leave a permanent damage to the phone screen...
Hi, i've been using the NVIDIA SHIELD K1 since january, and one thing that has always bothered me is that it doesn't recognize my fingers when i tap repeatedly, i play these rhythm games that requiere two or more fingers on screen, and losing because of the tablet not recognizing my fingers is painful, i tried rebooting and a number of stuff i thought could work, but there's no results, it even stops recognizing while i'm holding my finger (moving an app's location, for example).
This wasn't a thing in my previous one, it responded instantly with no stutters regardless of how many fingers i had on the screen, so i don't know what to do.
It's rooted with TWRP, i haven't used any ROM's as i don't feel like i requiere any, settings are always on max performance and i kill all apps that i leave and won't use so everything runs smoother, i also disconnect from internet when playing but it doesn't seem to do anything, can anybody help me with this?
Try doing a screen calibration; that worked for me.

I've tried screen calibrating, but that didn't work. Currently android 7.0 seems to make this less frequent.
Screen calibration worked here too, K1 tablet.
I accidentally found out about it yesterday btw haha
I'm having this problem with my NEW mi note 10 phone.
I notice it when first when I'm typing on my keyboard as usual speed.
It kept doing this phantom swipe across two finger taps.
I posted some videos to illustrate my problem.
Is it a software or hardware problem? (This problem is intermittent as well so it's really hard to pinpoint it)

ttps://drive.google.com/file/d/1-6M1e33Qxz8HXckkcLb3sWVTXG6fPHzv/view?usp=sharing (Using touchscreen tester, you can clearly see the phantom swipe across the two taps)
Anyone else having this problem except for me?
When this problem comes, I can't even properly play a game.
reformat factory reset - fail
reinstall latest miui global 11.1. 2 - fail
optimise animation all off - fail
gboard - fail
xiaomi keyboard - fail
SwiftKey - fail
turn off Miui optimization - fail
restart phone - fail
clear ram, clear cache, clear recent, speed boast - fail
CPU slowing down due to background processes?
Touch digitalizer got problem? (I tried shaking it gently, poking it but it does not affect anything at all)
As I said, this problem is intermittent. There are times when I can use it without any problems at all.
It's really weird.
It can be totally fine one moment and then it acts up again.
There's another thread about this. Most of us face this issue on all variants of the phone (Pro/Lite). This started with April or May update where Mi added a edge sensitivity control setting.
What happens here is that touch sensitivity suddenly reduces and it will be hard to do anything that involves rapid touch such as typing.
Lock and unlocking the screen or restarting the phone will fix this temporarily. There's no permanent solution.
Also when this issue occurs again, go to the settings and turn on Game Turbo for an app such as WhatsApp, without and then try typing on WhatsApp, you will see that the issue is gone.
We all are waiting for Mi to fix this. But I would advice to return the phone if it's under warranty though this is a software issue
