I received my XT926 as a refurb and I have been experiencing a strange screen issue.
I will often have my phone on a dock, charging and sometimes I will notice the screen is black like it's off, but the touchscreen is responsive. Hitting the power button does nothing but it makes the sound as if I had locked the phone. Hitting the power button a second time will turn the screen on like normal operation.
Very rarely I have noticed the screen will turn off while I'm actually using the phone and it's a weird effect. The easiest way to describe it is that it looks like entire lines disappearing randomly over a period of 1-2 seconds, going from all visible, then to all black, kind of like slatted blinds being closed, but at random. After this, it displays the same symptoms as if I had found the screen off while in a dock/charging.
Now, I don't want to say it's related, but I first started experiencing this on the Stock KitKat update from Verizon. I am currently using Cyanogenmod 12 nightlies and I am experiencing the same issue. It seems to be happening with greater frequency.
I have also experienced the blue screen effect when certain animations/elements/apps are up on my screen, but I think they are unrelated.
Also, there is a faint discoloration bar about 2/5ths of an inch thick uniformly vertically from top to bottom of my phone on the righthand side (just under where the notification bar would be if turned horizontal).
I've tried to find more information about this but my search results have been relatively lackluster (90% of the results are trying to sell me the phone or specification pages)
So I'm breaking down and turning to here. Does anyone know what's going on here? My current theory is that my screen is going bad. I have no intention of replacing the screen on this phone (would rather just buy a new one), so any suggestions that don't involve physical hardware repairs would be appreciated.
I thought i was the only one experiencing it.
The screen turning off with a weird effect happens rarely but yeah it happens. And the blue screen effect, i noticed it only happens when im on the youtube app when the video stops working because of my connectivity issues.
Im not rooted nor is my bootloader unlocked. On the latest system version. Sounds like a software problem but hey im no expert.

i also have this with my referb i made moto give me my money back and they let me keep the phone for me it was very rare but my new phone also had a really bad screen all yellowish and bad white balance in low light if you are unhappy with it call them and say you are unhappy with the replacement here is the white glove number 800-653-7185 they are more understanding and nice but you may lose you ability to unlock your bootloader on the new phone if it comes with the latest software just a warning
I have that screen off with lines slowly disappearing thing, too And, yeah, it's also a refurbished one, bought from one of the sellers on aliexpress... I thought Lollipop was the culprit or something like that. Oh, well... It rarely happens. And luckily I only have that, not the second issue you mentioned
I am having this exact same issue. The weird lines-to-black screen thing, and the flickering blue screen when watching video. Are you saying the solution is to call Motorola and ask for a new phone?
The blue flickering can be prevented by going into Developer Options and checking "Disable HW Overlays".
The discolored stripe on the screen sounds like burn-in; these AMOLED screens are much more susceptible to burn-in than the LCD screens used in older phones. Whomever owned the phone before it was returned to Motorola probably had something running on their screen continuously with a bright-colored bar at the top, likely in a car or desk dock. The screen is very easy to replace yourself with an eBay part, if you're inclined; it involves 2 screws and 2 connectors.
I've seen the lines-to-black thing exactly twice since I got this phone refurb two months ago. Sorry, I don't know what causes it or how to avoid it, but the workaround is quick and simple enough that I'm not worried about it, yet.

Hey guys,
I am going crazy here, searching forums did not help me at all.
The lower section of the screen keeps flicking, and not always, what do i mean by flicking, its like the screen at the lower section keeps doing like a strange low refresh rate, and has an old imprint of some old menus. Happens especially when there is the color of gray.
Made a screenshot of the phone, no problems, there, so its not a software rendering problem, might be a drivers problem though, or a defec tin the screen itself.
Frequency is high but not always, and am unable to determine when does that happen exactly. going crazy here, is this a defect? or all touch pro's have this?
Exact explanation summary:
1CM from the bottom of the LCD sometimes flickers as if that 1CM is having an extremely low refresh rate. Mostly happens when there is light gray, but not necessarily, and a soft reset for the phone does not remove it. It happens on random!
Hey,
Yeah it happens to me too! You don't need to do a soft reset, it actually fades away if you watch it closely! I don't know what it is either, and yes it is random as you have stated! I initially thought it was an application I installed as it only started happening after that, so I did a full hard reset and its still happening! Not sure what or how, but hoping next firmware version stops it!
Cheers,
mpls-te
As it happens, that's exactly why I've logged on here today! Any ideas whta the cause might be?
OK, good to see that others have this, so am not alone here, experts here, any ideas? other touch pro users, can you please leave your statements?
I hope its a driver issue.
But from what i noticed, its like, the screen is OFF, as in blank and no back light, but somehow, the application working on the screen before you turned off the device is somehow printing something on the LCD, something that we don't see, and when we actually start the phone and its back light, that OFF LINE imprint pops on screen. Something like that.
Its completely illogical, but dunno, can't find any sense here and am going crazy
Same thing happened to me and a few others as well.
See my thread here.
What rom is everyone using?
I've noticed a similar issue with mine, except rather than something software it seems like it's the backlight for the bottom 1cm of the screen flickering slightly. I don't see any weird pixels or inappropriate screen information, just a dimming/high speed flickering of the backlight in that same regionas yours. It comes and goes. Sometimes weeks without it, then maybe 3 times in a day for a minute or two at a time. Everything else works fine and whatever screen I go to displays fine.
I'm assuming it's a hardware problem with the LED(s) that light up the bottom portion of the screen, and I'm going to use it as an excuse to get a warranty replacement somewhere near the end of the warranty when the phone's getting a little old and worn.

Lool, evil, lets just hope that this problem DOES occur when you go to their shop for your replacement
Good idea though, might do the same thing except that i have to travel abroad to where i got the phone from to actually get the warranty working. Don't forget to re-enable stock SPL and stock ROM
It happens frequently enough I'll be able to get it on video just in case they need proof, but typically they just exchange by mail.
I just posted in another thread about this issue. I have run into the same thing a few times. The bottom portion of the screen flickers, and when i do things that have a dark gray or black screen I can see a ghost image of the left and right soft keys from my TFL3D home screen. It seems to be most noticeable when the screen brightness is set to max. To get it to go away I usually do a few soft resets, and then, if needed, i will turn off the phone and take the battery out for a while. I have never tried waiting it out to see if it will just go away on its own.

I see that everyone posting in this thread,that has their signature filled in, is using the Energy ROM. I find that very interesting.
i am having the same problems, sometimes touchflo3d will flicker at the bottom, near the edges. I also get text that can be read through other screens. Like on pocketshield i can see the left and right softkey words still at the bottom. its so odd !
P.S im on energyrom
I'm on NATF v2.2, not an energy rom. But then again, mine looks more like a hardware issue, as I've never seen any ghost images of text or softkeys, just flickering.
can somebody post screens?
maybe the same problem here...
hardreset, other roms > problem still there:-(
Same problem here and I am using stock rom!
here are 3 screens of my xda diamond pro, using latest official o2 rom and newest romeOS eng
hope you can see this prob?! same like yours?

Well, i doubt EnergyROM has anything to do with that problem, since my Stock ROMz had same problem, never got fixed with any updates HTC used to release. MAYBE some Cooked ROMs out there have this solved, if any, please let us know And my problem is nothing close to screenshots above :S

Dude, those photos are awful, after seeing them am happy with my phone flickering, its nothing close to this.
You see, in your photos, all three of em, you some kind of shadow effect, where text of a button for example has that same text beneath it 3x6mm, that is not my case at all.
My case is as follows, IF i am on the home screen for example all looks ok, except that the bottom 1CM of the screen is flickering. If i go to another window, either a total black one or any other screen, i would still see a ghost of the old home screen, for example, and only at the bottom 1CM.
Will post photos once i get my cam back. Cheers
similar issue
my issue is kinda similar, instead of getting the bottom 1cm or so discoloration or stuck pixels, I get streaks of red or blue on my screen. I have had this happen on each version of NATF I have tried, but don't remember it happening on the stock version (which I am tempted to try again to see if that's the issue).
Could this be a driver issue?
mind is even worse than all you guys, the touch screnn dose not response, and i have the energy rom on it, before it goes wrong. it just suddenly dose not response, than i send it to HTC, they ask for 425.00 for fix.... I will just send this to Asia and get some one to fix it.
But I hope before i send it out, some one can help me here.... anyway can fix it easy!!!!
Hi all, i have the same problem, here's another topic about it
http://forum.xda-developers.com/showthread.php?t=447891&page=2
sooo, yeah. my wife has the t959v. the screen cracked months ago, replaced it with one from ebay, works fine. a few weeks ago, it was involved in an accident and needed yet another screen replacement; ergo, back to ebay i go. installed the new screen yesterday, turn it on, all is well. for a bit.
now, the phone isn't currently, nor has it ever been rooted; pure stock tmo us 2.3.6. during boot, the splash screens and boot animation are gorgeous and perfect in appearance. the recovery menu is exactly as expected. android boots as you'd want it to, and then the display will do one of the following:
-work properly (rare)
-automatically turn off, capacitive buttons still lit, touchscreen unresponsive - turning it "off" darkens the cap buttons, turning it back on flashes the screen on for a half-second, then off, with cap buttons still lit (common)
-graphical corruption ("solarized" colors, completely wrong colors, pixel vomit in essence) (fairly common)
-screen tinting, blue most often, followed by pale yellow, then greenish, then red (almost constant)
-screen inversion - the display will show as rotated 180 degrees; grabbing a framecap in ddms shows it right way up. touches are also inverse; you have to touch where the onscreen element would be if it were displayed properly instead of where the element is; e.g. a button on lower-left will display in the upper right, upsidedown, but the screen registers the button when you touch the lower-left portion of the screen. (quasi common, equally infuriating and hilarious)
none of these problems will show up in a screenshot at all.
i can reliably reproduce any of the above by simply adjusting the screen brightness. this will, quite literally, cycle through every possible defective display mode randomly for a split-second before moving on to a different one as long as you move the brightness slider.
MOST of these issues are transient and are either fixed (temporarily) or replaced with a different listed issue if you lock/unlock the display. it feels like a hardware issue what with the solarizing and color horrors, but is acting like a software issue, considering that recovery and boot are perfect and have never displayed any of these issues. i tried gently flexing and stressing the case in areas that might be a weak connection point, but can't get it to bug out that way.
in no way am i suggesting that i didn't screw something royally in the reconstruction stage, but i tore down and rebuilt that phone 4 times with identical results, so i can guarantee it's not some loose ribbon connector or zif socket.
i beg of you, great minds of xda, what the balls did i muck up this time? any hope for a fix? are there different panels, drivers, something?
thanks in advance
OK, if your screenshots appear normal, then your phone appears to be working correctly!
or at least it thinks it is we can conclude that it isn't the rom, kernel, or anything that you can blame the phone for going screwy.
Try buying another screen??
The ribbon connector might be broken?
yeah, these were what i figured what my options were. it just seems odd that the boot process and recovery menus have error-free displays while only the full android os doesnt. oh well, i'll probably just have to make a stink about it on ebay or something.
thanks for reading
You might try a fresh flash before getting a new screen to see if it is indeed a hardware issue. If you want to try that follow the second link in my signature. You will not need to flash bootloaders since you are currently on KJ6.

hell, warranty's void at this point anyway, right? may as well thanks much!
welp, all went well, screen was perfect through the whole heimdall/recovery process, but the problems still exist in the os c'est la vie. at least my wife's phone is finally rooted, i suppose. thanks anyway!
Have you tried opening it back up and reconnecting?
yup, 4 times, but i guess one more wont hurt
[edit]
it definitely seems to be related (if not related, exacerbated by) changes to screen brightness. turning off autobrightness has helped minimize the issue, but it still presents itself semi-often during screen-off/on events. obviously nothing useful in logcat.

That's interesting and could very well be a hardware problem with the screen. You wouldn't see that in recovery as the OS isn't loaded to mess with the brightness in that mode.
Does it do it on-demand if you mess with the brightness slider?

you better believe it does. rapid fire cycles through every color until it can't take it anymore and turns off. if i take/refresh a screenshot through ddms and poke blindly at the screen at that point, it'll still take input which is a curious, difficult game to say the least.

It's that Pink Floyd screen. You're supposed to drop acid & watch the wall when that's going on. LOL j/j
Given that you're on a fresh ROM & the problem persists, I'm leaning toward a hardware issue man. Sorry.

as fun as that sounds, unfortunately i bet i'll end up just getting my wife a used phone on ebay or somewhere similar and using this one as a development monkey. i was assuming that it wasn't something i could fix but hoping otherwise... yeah, that worked out
I just started having this problem. It wasn't too bad at first, just the color changes, but then it started not showing a screen at all. Changed to three different roms, even back to the stock non-rooted KJ6 and gave up. Keeping it on a steady brightness is the only way to minimize the color changing. I thought your thread had a solution but...
I may try opening it up and fixing the ribbon. But otherwise I'll keep using it as long as I can tolerate it until an S3 or a new Nexus.

nawp, nothing even close to a solution here i did end up buying my wife a whole new replacement phone and turned the broken one into my api10 development device. for what it's worth, yeah, autobrightness off does help a bit for when the phone is actively displaying content, but after you put it to sleep/screen off and try to turn it back on, it's a crapshoot. for a few horrifying hours, the screen was upsidedown even in recovery/boot animation and would NOT flip back to right-side-up until i ran the battery completely flat.
is no fun, 'tis truth. sorry for your troubles.
Hello. The screen on my wife's S4G today suddenly started acting funny. First, it wouldn't display anything, but it seemed the phone was still functional. Then, with fiddling on my part, I got it working again, first fully and now in a sub-par way. The phone boots fine - and I actually unlocked the bootloader and rooted, and in the process went through a full reset, just to see if that would help anything - but the screen appears dimmer than before and there's vertical banding across most of it. The banding doesn't completely obscure the screen, but it looks bad. One other thing I notice, and this is reported in other places, is that there's backlight bleed in the lower left corner, even when you just insert the battery, and often on booting, there's a flash of pixelated "dust" across the screen, that's brightest in that corner and fades as it spreads out.
Anyway, TMI probably. Does this sound to anyone like a bad screen, bad connector, digitizer, or something else? I'm totally new to any of these kinds of issues, but would like to save the phone, if possible. TIA.
Umm... hi
I have two Nexus 5, one which is out of warranty and one brand new one.
So the first one I stopped using because the screen is acting funny.
Meaning suddenly turning black, image flickering, touch not working.
Sometimes tapping on the back of the phone helps, but I do forced reboots alot to fix it.
Also, mic is dead and speaker tends to ask for a tap to make it work here and there.
My second phone was meant as replacement, but after two weeks the backlight
of the entire right screen half started to go on and off several times a day. Tapping helped,
but I just returned to it get it replaced.
On youtube, you will find a huge amount of videos showing how various of those screen
and touch and reception and mic issues can be solved by simply replacing the 20$ daughterboard.
The one connecting the bottom half of the phone with the mainboard. This includes display, mic, speaker
and more. I intend to do that aswell on my broken-af first Nexus, but before that, I thought going to XDA
asking if anyone here knows why this component is so receptible to damage. It's not a moving part
and does not run near the CPU, so I really wonder why this part is failing to incredible often. Anyone can
tell me more about that?
Thanks
I have had this phone for one week and unfortunately have a problem with the small display on the cover. The display intermittently crashes and you are no longer able to see the time, charge status, signal strength, or any notifications without restarting the phone. Interestingly the crash does not affect the display of charging info when it is on the wireless charger. I am working with Samsung to get this resolved and they have assured me that they will replace the phone if necessary. So far they have tried wiping the cache, and having it re-imaged at one of their authorized repair sites with no success. Just wondering if anyone else has seen this issue or have an idea about what could be causing it. BTW...... I really love this phone otherwise.

I have observed the same issue. I've noticed that it recovers eventually but it is annoying as well. I called the premier service but they have not acknowledged it is a software bug yet. They had me factory reset but I am still observing the same.
I can also confirm it is not due to the case they ship with, nor the leather case, or finger grime that may be conflicting with the capacitive sensor. The rest of the phone knows the main screen is closed. My suspicion (speculation) is that it is the software as the cover display is really the only new hardware portion, in regards to most of the components from S10 parts bin, or Fold screen tech which has been pretty mature from a design standpoint.
Love the phone, hope they they can resolve this in an update sooner or later. Please let us know if its common to all.
Thanks.
I have the same issue. Been using the phone for about 12 days and the cover screen goes bonkers. It will appear some time but only clock and battery life, can't use it for notifications nor calls nor selfie camera. Plus open phone to answer is not functioning
This is my second Z-Flip - had the original one on release day and now the 5g version. Yesterday, out of nowhere (for the first time on either phone) the cover screen went blank. It works still (I can change songs and answer calls, for example) but the screen is black. This is 100% a software issue. Called Samsung 'premier' which puts you in the line for normal support, when they pick up they transfer you to premier (makes no sense). They suggest a factory reset. Odd thing is 2 calls today actually showed on the display. No rhyme or reason. I have tried powering down, restart, and safe mode. Very frustrating.
I'm also having this issue, I had a different issue in the past where the phone would not recognise when it was opened or closed and just behaved like a regular smartphone with screen on off. The cover screen also came on at the same time as the main screen so basically the phone thought both were one display.
This time I am getting the issue as above, the screen is black, pressing power does not bring it up (always, sometimes it will randomly show and I can use it, before a factory reset I just did it wouldn't be functional as touch only worked halfway, I could drag it left or right but it would just stay where it was, thinking my finger was still on it.) if I press the power repeatedly sometimes it shows, sometimes it shows offset so only half the display lights up and has moved everything to that side and cropped it. It's completely a software bug, my phone has no scratches or dents and is in great condition. It's a newish model as my original Z Flip got replaced by my network by a 5G model.
