Hi everybody,
bought my AM7 today and have been very happy with it so far. However, there`s a graphic glitch going on while playing games (namely Dead Trigger 2 and Castle Clash), sometimes even in the UI (changing home screens, browser, e. The thing is, that the lower (right in the landscape mode with Huawei logo on the right) half of the screen "flashes" a grainy images, as on an untuned TV channel. I tried to take a screenshot but as long as the flashes occur randomly and last only for like a 0,1s, it`s quite impossible.
I really can`t tell whether this is an hardware and/or software issue. Is this a warranty issue? Any help will be much appreciated.
Thanks,
M.

Received this phone (THL W8S) 5 days ago, and straight out of the box it has had a serious issue where the phone will lock up, the screen will fade slowly to black, and then reboot itself. The problem occurs both after factory resetting AND in safe mode.
The phone is unrooted and running the stock ROM.
Basically during use, the screen suddenly becomes unresponsive to touch and the physical buttons (home, volume, power) all stop functioning. As soon as the phone locks up this way, the screen slowly fades to black over about 60 seconds, at which point I have to leave it to fade completely before it reboots itself.
It happens most frequently when using any browser (stock, or otherwise) taking from less than 5 seconds to around 5min before the random lock up occurs) but also happens when scrolling through messages; scrolling through emails in either of the stock apps; using a compass app which came pre-installed (very quickly).
Initially I thought it might have to do with WiFi, but problem also cropped up with WiFi off, using 2/3G. Then in troubleshooting also managed to get it to happen using the camera (lot of motion, and repeatedly taking snaps).
Also odd is that the batteries I received in the box were generic black ones, not the official stamped/logo'ed THL ones I've seen on every website and every unboxing of this particular phone. So while there's a possibility this may be a battery issue, the fact that the phone hasn't done this while using a more battery draining app (Beach Buggy Blitz; Rayman Jungle Run) makes me think this is a deeper hardware fault related to , although I don't know enough about voltages and such to rule it out completely.
I have a couple videos showing the problem, but unfortunately I'm not allowed to put the links here. Should both be easily found by searching:

Hello, I wanted to inform you that lately the reboot occur concurrently with application updates.
They are like your impressions.
Best regards
THL W8S the screen fade and reboot too!!
Hello!
I received the phone on 12 September. The screen faded from the first minutes of use. Yesterday I came three times. In "THL mobile store" recommend updating the firmware. But the update I have not found anywhere.
any suggestions
Thank you very much in advance.
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?
http://forum.xda-developers.com/shield-tablet/general/adjust-touchscreen-sensitivity-t2963326
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...
Does anyone has multi touch issue when playing pubg? Mine has a weird joystick bounce and it happens randomly, basically my character would stopped walking and I had to touching the screen and drag the joystick one or multiple of times in order to fix it. Again it happens randomly...
Hi everyone,
My Pixel 2 has a weird multi touch issue while playing PUBG, I am curious if anyone of you plays PUBG has the same issue like me..?Basically I have had issue when especially there're enemies around or team mate dies. The walking joystick would bounce back to centre while I'm walking manually, it is very very annoying especially in situation like this. Every time it happens, I have to re-push the walking joystick to start walking again, then it could happen multiple of times within the second. I've tested on my S7 Edge, iPad mini 2 and there's no such weird issue... I assume it has to be my Pixel 2, the device itself is smooth and runs great but no good for PUBG game
This has to be one of the rarest issue that it will not get it fixed anytime soon, I am hoping someone with same issue to talk with... Thanks for reading!
I have this same issue with my Pixel 2. No fixes.
