After hanging up from a phone call the top left corner of my screen was really bright. There were two vertical lines down the screen and the screen was transparent and flickering. I could still see my home screen and the screen was functional. I restarted the phone and it was still acting up. Only after turning the phone off for a few mins did it stop. Has anyone else experienced this or have any ideas on what would cause it? I haven't had any issues with the phone, no drops or anything. Currently running aokp with matrix kernel.

I had this issue too. My phone just arrived today. In my case the problem occurred after power cycling the phone (trying to get the WiFi to connect.. grrrr) The boot process was fine but once I got to the launcher my screen was flickering like a strobe light. I tried to power off and back on and it still happened. I didn't give it several minutes like you did so I'm not sure if it would have gone away. Since I hadn't really configured the phone yet I simply did a factory reset and it was fine. Seems to be a software issue. I hope it doesn't happen again but if it does I'll see if just leaving it off for a while helps. I hope so because I don't want to have to factory reset all the time!

please help me with my phone or let me know if it has happedn to any one else
Well i was on my phone and everything was fine however when i reset my phone with the stylus it turned back on but the screen was just black... now i can touch the screen and i hear the clicks and beeps as if the touchscreen is working but i cant see anything
I have a black screen also
I'm having a similar issue. It just began a week ago. My screen began fading out but when i'd open the keyboard it return to normal for a little while and then start to fade again. now its completely black and i can't use it at all.
i charged my phone completely and when i turned it back on it worked and it seems thats all i did because everything else was not helping but when i charged it complete it worked again
Hello, My G1 has just suffered a problem, i was scrolling down a web page and the screen faded out like it had lost power but the backlight was still on, the keys lit up and it still could make the trackball clicking noise when you moved it. I took out the battery and left it for 5 minutes and rebooted my phone and the screen turned on for about 3 seconds and faded out like before but it did boot into android as I heard the notification/startup sound. I think that the screen has burnt out but im not shore so has anybody had this problem before and/or might know how to fix it
Just some more infomation, If the screen dies and I leave it for a few minutes, when I unlock it or slide the screen up, the screen works for a few seconds but then fades. Also the fading looks like the screen lost power or like its losing pixels
From my experience with phone hardware this doesnt look like screen problem, but rather the lamp driver in the motherboard. the only way to narrow down is test the motherboard /screen with another phone.
If this is the case, it might require servicing the backlight driving circuit, which by far requries soldering/desoldering some components in motherboard.

had the same problem its a hardware issue. tmobile sent me a new phone no questions asked
Thanks for the replies, it seems that it has fixed its self as I've been using it for about 5 hours and no problems so far, I'm using it right now to type this, if the problem persists I will try and fix it or just buy a new one
Hello good folks,
I would like a bit of help with sorting my phone out. As of Thursday morning (2 AM or so) my phone has a black screen. The phone switches on, the touchscreen works (I can unlock it, put it to silent, hold the power key and tap the places on screen that would normally switch it off to do just that), the volume keys work, I can receive calls, the back light works.
Everything is as it should be, but I cant see a damn thing!
I should note that this happened once before, about a month ago and a few hours later it was back to normal. Also, I have noticed over the past few months a very small black circle at the top edge of the screen, about half a centimetre in diameter.
Please help!
Kindest regards.
It's the first time I read such an issue, your screen's probably defective.
To eliminate a probable OS issue, does the bootloader appear flawlessly ?
No, nothing appears at all. The screen is completely black at all times!
Your screen is malfunctioning, I don't know what's causing it and I don't know if you can fix it yourself either.
I think you are better off sending it back, if still under warranty.
Otherwise, ... ?
This just happened to me NOW....I'm waiting hopefully it will fix itself as i hear the HD2 heals itself LOL
I've actually had no luck finding anyone reporting this issue, but it's one that is really starting to bug me...
Sometimes, when I turn the phone on, rather than the traditional lock screen, the camera screen that you can ordinarily get to from the lock screen shows up...but it's not the full camera screen; it fills up like 3/4 of the screen, and the buttons have no functionality. Almost as if I had swiped over to the camera, but it froze about halfway through opening it.
I have tried to discern a pattern here, but there doesn't appear to be one...whether I turn on the screen with the power button or knock-on, it still happens randomly. I thought for a while that it only happened when I locked the phone with an app running on the screen, but that proved to be incorrect as well.
Like I said, having no luck finding anyone else reporting this. Has happened since I got the phone, even after updating. I've got a feeling its just a glitch I'm not going to do anything about, but if anyone has had any luck making this stop, I would greatly appreciate some advice!
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?
