Odd graphics bug.. - G2 and Desire Z Q&A, Help & Troubleshooting

Have been having a strange bug the last day. My screen will display everything in a sort of negative pixelated way, I've no pictures of this as it only last a few seconds or goes away when i put it to sleep and wake it. I reflashed CM 6.1.1, full factory reset and cache clear etc before flash. The strange thing was the clockwork recovery text was blue instead of green, and the android icon was also negative??
Anyone have any ideas? I'm assuming it has nothing to do with the rom as it was also happening in clockwork, could it be a processor issue or even a wiring issue? If the problem gets worse ill reflash stock rom and send it back but has anyone else seen this issue????

its probably your ribbon cable or a defective screen if so try getting it exchanged

Blank screen

I have been using CRC 12.11 for a while. A strange problem started all of a sudden. My screen went white although it is working. Soft reset didn't solve the problem. Hard reset solved the problem for a while and then it came back. I noticed this at the time it happens. While everything is fine, the screen fades out, a few lines like scratches appear and then the screen stays white. I hear system sounds, the phone rings but no display. What has caused this?
I flashed another ROM but when my phone restarted it was still white. I hard reset and now I am waiting. If it reappears, it means it is a hardware problem right?

I had this same weird issue once on my rom, i think it's because of the Big storage bug.. Flashed OEM rom and went away.. only saw it once!
I reflushed several ROMs that I used to have before without problems and still have the same. I can't install OEM, I think it's because of the bootloader version but I don't remember exactly the procedure to correct this and I don't know if it's worth the effort in downgrading to OEM.
Another thing I just noticed is that the screen is not aligned in the center. There is a small gap on top of the screen as if the image has moved downwards. Maybe this is the cause of the problem. Noone had similar issue? I don't believe it has to do with big storage because I have been using it fot a while and this never happened before, not even once.
Any ideas will be apreciated as my only choice right now is to buy a new phone.
same thing
i´ve been looking around and some people say is because the magnet in the pouches, affect in some way to the screen ribbon or something like that.
that is a common problem with the hermes, if u search the forum u'll find a couple of threads like this.
it's a hardware problem, next symptoms will be the green/red buttons and d-pad stoping to work
I know theres a few links in the FAQ about the white screen issue, its fixable in some cases.
problem solved!!!
i just took it apart, one of the ribbons which connect the green and red buttons was kindda folded also the connectors , so i just blow some compress air and tried to unfold the ribbon, put it back together and voila! like new. Just be carefull cause it´s like fragil.
same exact problem word for word
The same exact thing happened to my hermes. I guess I can attempt to put mechanical skills to work and fix this problem.

[Q] home button and lower left screen no longer works

I am running miui 12.11.1, stock kernel. My droid incredible as the AMOLED screen. My home button and the lower left part of the screen no longer respond to touch input. I have to rotate the screen to use parts of my screen now or I can't type in the "a" on the keyboards, or pull down the menu in landscape mode. I've wiped cache, and full wipe, but it has made no difference. I also cannot mount the internal sd card but that is a known issue with this rom I believe.
I've also tried going to a completely different rom CM 6.1 stable. but I have the same issue.
Ideas or assistance would be appreciated.
this sounds like a hardware issue and is most likely unrelated to ROM/kernel/recovery
Sounds like the digitizer screen. Same thing happened to me. Look on Ebay for a new one.
this happens with certian Dinc's. i bought a new screen to fix my home button issue because they are linked, i ended finding out it was a loose cable but according to HTC its a rare problem and was isolated to a few phones
eh. . that is ok. If it is a hardware issue than I'm just unluckly. I guess I just need to remember to rotate the screen left instead of right. Is there an easy way to map the home button to the search hard button?
I guess if it is really annoying I'll sell it to one of the devs here who could put it to good use.
Doubt its a hardware issue so test it before listening to anyone on here. I have miui as well and I have the same problem then I did a nand and flashed a new rom and it worked but I restored and the nand and the problem was back. I thought it was kernel but I flashed different ones but that isn't it...i flashed the zip for data throttling instead of editing it myself but I doubt that is the prob...so I have no cle right now I was just going to give up because now I don't even get any calls so make sure you test to rule out a hardware issue because I doubt it is bc I have the same issue and they keep getting worse until I flash a new rom. I'll try to figure it out. Ley me know on recent changes you made so that I can have some help trying to figure it out.
Well, Like I said, I wiped, factory, reset and flashed a completely different rom (went from MIUI to CM Stable) and one side of the screen was unresponsive. I turned off the phone to put in a battery and now I have all my buttons and everything seems to be working again.

I've heard of issues with extended batteries where the pressure distorts the screen so it doesn't work...
Could that've been the case?
I doubt it was the battery, I had the original battery in there when it was not working and I'm using the extended battery now and it is working, both batteries have identical physical dimensions. It may very well be a hardware issue, I noticed that when I was having problems, I could not mount my sdcard on my pc. The cable was plugged in, the phone asked if I wanted to sync with the PC but it never showed up in windows. I did it just now (running CM6) and it works. The usb cable/port is underneath the home button so maybe that port is just fragile and causing issues? I never liked the location of that port, it should be on top of the phone or underneath, away from screen as much as possible.

[Q] status bar wont pull down in portrait mode

Very annoying!!!! This is persistant even when flashing from AOSP to sense! Works fine in landscape. I have tried wiping the cache, boot, and data and nothing is working. What causes this? I have seen other people with this problem in other fourms but no one has an answer.
Define "won't pull down." Like, it comes down and immediately goes up? Or you can't even "grab" it?
Try flashing Calikulin's format all (after a NAND backup), flash another ROM, and see if the problem persists.
The only thing I'd suspect being a real problem is if that part of your screen is dead. Do other touches work there?

I can't grab it. The pulldown wont... well, pull down. Tried caulkins format all and flashed different roms that's why I'm worried. Landscape works though, and I can set a swipe action in adw Launcher
Could be the top section of the screen dying. Get one of the many draw apps from the market, and see if it's registering touch up there.
Try taking your battery out and holding down power for 15 seconds. This will reset hardware. If that doesnt work...unroot and get a replacement. This happened to me a while back. Potrait wouldnt drag but landscape would. Touchpanel problem. Also you could try flashing the tp imgs again from toastcl eng-PC36IMG. I never tryed that when it happened to me

[Q] Screen issue starting today

I'm trying to diagnose a very odd issue that started this morning. I woke up and checked my phone and instead of getting the normal screen I just had a battery image showing 100%. I've never seen that charging image before today. I could not get to my phone screen so I rebooted the phone and now the screen will immediately power itself off after a second or two. I have been able to get it to the phone screen a couple of times, but if I touch the screen it powers off.
I am running Juggernaut 4.1 and have had no issues before today. I didn't install or update anything yesterday although I can't get to the phone to see if any auto updates have been completed.
I went into clockwork and I was able to navigate though and wiped both cache and dalvik hoping that would clear it up. After reboot it was the same behavior.
Before I spend my entire Sunday wiping and reloading my phone can anyone give insight into this problem? Most of my searches for screen issues have popped up the general display problems with the greys and blotches.
ETA:
Not sure why my brain didn't process this first, but I am actually able to unlock the phone (sometimes) with widget locker. If I tap the screen outside of the status bar then the screen powers off. I can interact with the status bar but I can't click the screen to get the phone into USB storage mode so I can't get anything copied off. I'm going to do a recovery backup and re-install Juggernaut to see if that clears it up before I start thinking hardware issues.
Not really to experienced with an issue like that, but perhaps before you fully wipe you could backup and restore the same backup. I had a application issue that I couldn't fix and even though the backup would be the same somehow it fixed it.
Sorry I couldn't offer you more.
As far as the battery showing up, I see the screen all the time when it's shut off charging.

Note 4 stuck on yellow Sprint startup screen

Twice this week my alarm didn't go off (luckily I set a backup today) because sometime throughout the night something happened. When I woke up the phone was frozen on the yellow Sprint Spark startup screen. I needed to pull the battery and everything started up fine. I updated to Lollipop about 2 weeks ago which is where I'm guessing the issues stem from.
Is there anything I should try other than restoring to factory and starting over? I'd prefer to not have to wipe everything from my phone but these issues are becoming problematic. I am not rooted.
Thanks.
You answered your own question. You need to try a factory reset. Problems happen when you upgrade to new software without wiping.

Dschachm is correct. Then if you root and install TWRP you can back it up with all of your apps and data. So if there is ever a problem again, just restore and done.
So I ended up doing a factory reset and while the phone certainly started running faster with better battery performance after the reset I'm still having this issue. I would say it occurs 2-3 times a week. It has only occurred overnight which is typically when I charge my phone so I'm pretty sure it is related to being left connected to the charger. The majority of the times I will wake up with a dim yellow Sprint screen and everything else frozen though occasionally the screen will be black with the led notification light red. In both situations the screen will not respond to any button pushes or holds and I need to pull the battery and then everything will start up fine.
Does anybody have any suggestions here on what I should do? I guess I can try and restore one more time and see but I don't really know why it would be different and it is certainly a pain to keep restoring the phone and losing all my settings. I definitely don't want to root now since I believe that voids the warranty and if I can't figure anything out with this I'll certainly be requesting a new phone from Sprint. Before I start dealing with Sprint though I thought I would check here first. Through all my searches on the internet I haven't seen anyone else complaining about this problem.
Thanks.
I've gotten the sprint yellow screen and nothing else.phone doesn't turn on? When I try turn it on after removing batteryou I get the android figure and phone turns off? How can I reboot or start the phone..?and can I save my contacts?
