This problem recreates multiple times per day. It seems like the LCD gets powered, but there is no graphics signal.
When I turn on the tablet the LCD Backlight will come on, but there is no graphics on the screen. At this point, I cannot turn the LCD off by using the switch and there is no other action I can take.
I have to wait until the LCD turns itself off (approximately 20 seconds) before attempting to turn it on again. It typically works fine the second time, but not always.
I have called Google and they have issued an RMA, but I am curious if anyone else is experiencing this issue to determine if this is truly an isolated issue.
Thanks.
I began testing with a Bluetooth keyboard and have see the same behavior when waking the tablet up using the keyboard. This would eliminate it being anything to do with the physical power switch.

I am currently in discussions with the screen's vendor about the issue, but I figure somebody might have some advice to offer here too. I purchased a replacement screen for my Vogue after I cracked the factory LCD. Touch membrane was fine.
Opened the phone, pulled out the old LCD, replaced with new one, etc. At first, the "new" screen seemed to not power on at all - then after several cycles of open phone/test connections with old LCD/rebuild with new LCD I finally got the backlight on, yet the display itself seems to not be working. There is an ever so slight greenish glow in the bottom left corner of the replacement screen when the backlight was on.
Several hours later, during which time the phone just sat on my desk idle (but on) I hit the power button to turn on the screen and was dismayed that the backlight did not come on (simmilarly to how it was originally.) I am certain the phone was assembled correctly, all connections are secure, etc.
The vendor suggested adjusting brightness/contrast settings, which I skeptically tried to no avail with MyMobiler. So at this point, the backlight seems to work when it wants to and the display seems to not work well at all.
Has anyone else seen anything like this?
My Atrix's screen randomly stopped displaying anything. You can see that the backlight turns on and off but nothing ever displays. The screen isn't physically damaged and the touch sensor is also functioning just fine. If I plug it into my Lapdock - I can use the phone with no issues, I'll just never get any sort of display on the cellphone's screen (Outputs to Lapdock's screen just fine).
Any ideas or suggestions?
are you able to adjust screen settings when you're on lapdock? (and does this change anything?)
It does sound a hardware issue with your screen... maybe others on here can offer more help
Just tried playing around with the settings - no luck
Do you think maybe the display cable somehow disconnected? I'm not sure how the Atrix is designed but I think you'd normally have a separate cable for backlight, touch, and display. Maybe I'll try disassembling it and report back.
Hi All,
Not sure if this a bug or not, but if you are touching the screen (While off) and turn it on, the touch is broken. its like the calibration is completely messed up and the touch is unusable/uncontrollable. I can easily fix by Turning the screen off and on again not touch but it is a bit annoying.
Is this the way that android works, does it calibrate the screen touch every time you turn it on?
Does anyone know if i can fix this is any way?
I get this issue 2-3 times a day, it's not always from touching the screen though, for me it just seems to happen randomly. I wasn't able to reproduce it by touching the screen beforehand.
Hey guys,
i noticed something strange on my tn7.
Sometimes (maybe 50% of the time) when i open the (original) slide cover to wake up the screen, the touch screen is very unresponsive.I can touch, but it notices only ~10% of what i am doing and is extremly laggin. when i then turn off the screen with the button and turn it on with the button again, everything is fine.
Also when doing this i have to wait for the screen to go off completly - if i wake it when the backlight is still on but the screen is black, the issue stays.
This never happens when i wake the tab with the button though, only with the slide cover. Thats what is kinda strange i think..
Anybody got an idea on how 2 fix this?
Running rooted Stock Kitkat.
Thanks
This is a problem that has existed since this tablet was released and persists still to this day. All you can do is cycle the screen off/on with the power button, unfortunately. Seeing as how this hasn't been solved in the last 10 months and Nvidia is showing signs that they're abandoning this tablet to focus on the Shield Tablet, it will probably never be fixed.
Screen lag
I have a similar issue on mine. I've had mine now about six months and it's very intermittent but at certain times, especially when the battery is low, the keys down the left side lock up and become unusable. I bought the tegra note 7 because of the stylus which I prefer to touching the screen with my index finger, but I don't much like the stylus itself which could have been made of better materials I think. I also find that sometimes it doesn't register clicks, then it will be perfectly ok for a little while. I had hoped with the tegra 4 and the much hyped stylus it would be very responsive but it's inconsistent. Anyone else recognise these flaws?
I also get this intermittently but only ever when waking it up with the cover, its never happened when turning on with the button. When it does happen a quick off and on with the button resolves the issue
I have a Moto G4 that has had the touch screen become very erratic lately. This issue appeared shortly after a factory reset. The phone is stock, recently OTA updated to NPJ25.93-14.7. It frequently freezes and won't respond to touches of apps or the home/back/recent buttons, and won't side scroll to the next screens properly. Sometimes random apps launch on their own without any touch, and if you try to quit them with the back button they keep relaunching. The problem is intermittent.
I activated "Show Taps" in Developer Options and when the problem is happening there is a tap dot near the lower right side of the screen. It bounces up and down a little bit and vibrates sometimes. When this dot is visible tapping on anything else like app icons or buttons usually has no effect, however the taps are shown on the screen. If I hit the power button to make the screen go black it will sometimes recover when I reopen the display, other times it takes a reboot.
Wondering if it's a hardware issue, a guy at a Verizon store who seemed to know more than most said it was a faulty digitzer--it's seeing touches where there are none. I've replaced displays successfully before, would just like to have a confidence level that the digitzer is really bad before doing that, as opposed to a software or other hardware issue. Any ideas about problems that might cause this problem, like other hardware or a corrupted OTA? Seems very hardware-ish to me, but I'm no expert.
I have Drive links to a couple of short videos on the symptoms, can send links. Much appreciate any insights.
Mine has that issue as well. It will spam the 9 key on the unlock screen or anything in that spot if an app is open or what is on that spot at the home screen. I have to double unlock the phone to fix it. I guess turning the screen on and back off resets it for that session. But it's mostly every time the screen goes dark and comes back up I have to turn the screen off and back on to use the phone.
I had a similar problem and was able to send it in under warranty and get a replacement phone
G4 Digitizer or ghost touch
Apparently this is called Ghost Touch issue, and affects many phones. One solution tried is to disable Battery Optimization for System UI and Google Now Launcher in Settings>Battery>Battery Optimization. That seemed to cure it for a week or so, but the problem returned today. I can sometimes recover form it by hitting the power button to blank the screen and then reopen. Other times it requires a reboot. I see all kinds of alleged solutions out there from dimming the brightness to removing tempered glass protector to using a slow charger, but those don't seem like real fixes but workarounds (if they even work at all). Any other ideas?
