Screen Glitching/Buggy - ZenFone 2 Q&A, Help & Troubleshooting

im running into an issue with my phone when the lowe half of the screen is becoming very glitch and distorted, i looked up the issue and was wondering if there has been any fix for this.
my phones warrenty is out since ive unlocked the boot loader but even if i did i dont have a service center anywhere near me. so what can i do about my phone, i dont really have the money to get a new phone.
is the zenfone an easy phone to open up and reconnect the display.

Have you verified that this is not a software issue? Although it does sound like a hardware issue, has this happened in the bootloader and/or recovery and if you don't know could you take a look? On the topic of dissembling your phone, there are guides online and I haven't tried so I don't know how easy it would be.

[Q] Touch Screen gone haywire

After flashing the stock google (yukju) roms on my galaxy nexus, everything went fine for a couple of months and now I am getting weird haywire issues with my touch screen. Without me touching anything, the phone will act like a part of my screen is being touched, it will not respond when I am indeed touching it at times, the screen will flicker back and forth and generally act strangely. Then for the other 70% of the time it is fine. I have re-flashed all stock roms, did a factory reset, and the problem persists.
Is anyone else having these problems?
any idea what to do next.
After contacting my provider, they said they cant help me because I had unlocked the phone. I have since relocked the phone so I might try calling back and seeing if it will fool them, but I doubt it. Now that I have re-locked the phone should I try to deal with Samsung?
Any help appreciated!
It sounds like a hardware issue. Most likely the touchscreen itself is bad. If you still have warranty or insurance coverage then bring it back to the store and tell them it is defective. By the way, NEVER mention that you have ever unlocked or rooted your phone.

Thanks for the reply. Im worried that, like you say, it is a hardware issue because I bought it used, and therefore will probably have problems with warranty/insurance. My carrier has already said that they wont help me with it so I would have to go right to Samsung. Any tips on dealing with Samsung? I have already returned to stock and re-lock the phone and I never rooted it, I certainly wont say I did anything to it in any way. Anything else I should be aware of? Will they even help me out since I wasn't the one who bought the phone in the first place?

Although most manufacturers offer a 1 year warranty on hardware, I doubt they will honor it since you were not the original owner. Your next option is repairing it yourself. It took a look at prices on eBay and it looks like the digitizer (touchscreen) for a galaxy nexus goes for about $30 and the combination of digitizer and LCD screen go for about $150. I don't know how difficult it would be to separate the digitizer from the LCD on your phone, but $150 for the set is still better than buying a new phone.

As has been said, it is probably a hardware issue - I had an HTC Desire S before my GNex and had the same issue with it, started all of a sudden. (The screen would go haywire as you said, almost as if a ghost was pushing buttons quickly - that's the best way I can describe it). Mine did not have warranty coverage because I had rooted and unlocked it but the HTC rep was helpful and said it happens sometimes because of moisture or humidity or some such thing and to replace the lcd/digitizer. Cost me a little ($110) but phone was as good as new after that, used it for six months before selling it and buying the GNex.

Potential Brick, Unsure How To Proceed

Hello all.
I am an HTC guy through and through and have never owned a Samsung device. I'm familiar with HTC's S-OFF/HBOOT/bootloader stuff, but I'm not really all that clear on how it works for Samsung devices. I promise I've tried to do some reading before hand before coming to you, including looking at other threads, but they don't seem to be the issue I'm having.
I'm trying to help a friend out who has an AT&T GS3 that I unlocked for him and put an AOSP ROM on it a few months ago (don't worry, I made damn sure it was the AT&T version and no other carrier/international ROM).
He came to me today telling me that his phone suddenly turned off, and was not turning on again. I figure it's probably just a corrupted partition, something that I could fix with a reflash or something like that.
However, when I look at it, it seems to be something potentially worse. The phone did nothing with the battery in, so I took it out and put it back in. The phone very briefly vibrates, the Samsung logo shows for about 1.5 - 2 seconds at most, and then the screen goes dark.
When I try to enter Download Mode, I'm able to get to the custom software "warning" page, where I press Volume Up, and it shows me Download Mode and "Waiting" (as I expect it to) but then the screen just goes black again after about a second or two.
It's roughly the same with Recovery Mode, I can catch a glimpse of what looks like CWM (but I'm not entirely sure) and then the screen goes black.
If I choose to forgo the battery altogether, and I plug it in straight to the wall, the red LED on the top right lights up for again maybe 3 - 4 seconds at most, the light goes away, and the phone briefly vibrates, shows me the Samsung logo, and then goes dark.
I'm confused. I don't know if it's a brick, but then again, to me as an HTC user, "brick" means Qualcomm USB Download mode. I've also read about this infamous Samsung Sudden Death Syndrome that struck some of the 16 GB models that Samsung sold (and yes, you guessed it, this is the white 16GB model).
I don't really know what other troubleshooting options there are (but as I said before, I'm an HTC guy). If any of you have any sort of advice I would love to hear it.
Thank you for your time.
I've seen several users on here in the last few months with this issue. I worked with one of them for awhile trying to get it straightened out but couldn't resolve the problem. Some of that was due to the nature of the problem and some was probably due to the fact I didn't have the phone in my hands to help the new user better. I believe the user was able to get an exchange at an at&t service center. Sorry I can't offer more assistance. Keep us posted if you get a fix.

I appreciate you trying. I know it's such an odd issue that it's really hard to diagnose. I thought perhaps it might have to do with the battery somehow being "bad", but then the problem would be gone when I go AC only.
He's not against the idea of going to AT&T, but I feel bad; I convinced him to unlock and let me flash a new ROM so I feel that I should at least put in a good effort to make sure there's nothing more I can do.
Yeah, the biggest problem is that once you get into recovery or download mode, the device reboots/loops. This eliminates the possibility of any kind of flashing or wiping.
You might have a bad motherboard. If I was you I'd take it to att for a replacement. BTW if he doesn't have insurance for the phone they do have open enrollment , I'd wait a day or two after enrolling to submit a claim.
Wish you the best.

It's a realllly long shot but he could contact mobile tech videos and tell them his issue and see if a jtag repair would help. If it's hardware of course he is out of luck but it's worth a shot and a lot cheaper.

[Q] Stuck at "erasing userdata..."

Hello,
Recently my Nexus 7 (2013) battery ran out because I forgot to charge it. Since then, it won't boot back into Android when it's turned on - all I get is the black screen with "Google" written on it. I have searched all over the internet for the past few days, but I'm unable to find a solution. I'm hoping that someone here can help me, because the tablet's warranty has expired and I'm completely out of ideas. Here are the things I've tried or noticed:
I can't boot into Android. The tablet gets stuck on the black screen with "Google" written on it.
I can access the bootloader and interact with the tablet via fastboot.
The bootloader is locked. Trying to unlock it via fastboot oem unlock displays the "Unlock bootloader?" screen on the tablet. After I select "Yes", the command line output on the computer shows the following output, but doesn't get any further:
Code:
...
(bootloader) Unlocking bootloader...
(bootloader) erasing userdata...
Trying to boot into recovery mode from the bootloader results in the tablet being stuck on that black screen with "Google" written on it.
I have removed the back cover from the tablet and reconnected every exposed connector. I couldn't take the battery out because I don't have the appropriate screwdriver. Doing this changed nothing.
Any help would be sincerely appreciated. At this point I'm worried that it is a hardware issue, but I'd like to exhaust all options before declaring it as such, as it would essentially mean the tablet is going in the garbage bin.
How long did you let it sit at "erasing userdata"?
I don't recall specifically on my N7 but I know when I unlocked the bootloader on my 2013 Moto X it seemed like an eternity, which was mostly because there is no progress indicator, it just said "erasing userdata" and sat there for a while. Probably like 5-10 minutes.

Well that is surely too long. Not sure what else to suggest. Someone else with more experience might able to help.. It sounds like your partitions may have been messed up somehow, which I have seen others post about recently with the updates. I'm not sure what causes this or if there are any fixes, but I know there are threads about people being stuck on the Google screen and having issues after the update to 5.0/.1/.2.

Hi,
i had exactly the same problem. I tried everything to fix it and no luck. I had to resort in sending it to Asus for repair. Unfortunately my warranty has expired. I just got a quote from them saying the motherboard has gone and it will cost me £250 to repair!!!!! I almost fell off my chair. A brand new 32gb tablet will cost be around £180. This is surely a joke? I will be giving them a call tomorrow to complain!
I hope yours is still under warranty because it is most likely your motherboard that has gone. I've read a few others having the same issue and its been the motherboard.

Thank you for your response.
I'm sorry to hear about what happened to you. I've been reading around and guessed it's probably a hardware problem based on other people's similar experiences. Unfortunately my tablet is out of warranty as well, and I'm definitely not going to spend more on the repairs than I would on a brand new tablet. I regret purchasing the tablet in the first place, I really expected it to last longer than a year.
If you can, please let me know what ASUS says about this, if you intend to call them. They don't have a subsidiary in my country, but if you get lucky, I might press my chances as well and perhaps I can get this repaired for a reasonable price.
Mine has lasted 5 years more but my Nexus 7 has ended its days the same way as yours. Stuck at google when switched on, and stuck at bootloader when triying to flash it.
Time to go, it seems.

Phone turned off and won't turn back on?

I was listening to a podcast and out of nowhere my phone turned off. I tried to turn it back on, but it keeps getting stuck on the LG start up screen (almost like a bootloop). I manged to get it to turn on once and it turned itself off after a couple of minutes. I tried taking the battery out, but that didn't help. Any help would be greatly appreciated.
I looked into it more and found out it happens to a lot of people. Im going to try to get a replacement phone.
I have a question about the warranty though. Apparently they may not fix the phone if there is physical damage to it (because they cant tell if its your fault it broke). My screen has around 5 cracks on it. Has anyone tried to get lg to replace/fix your phone with physical damage to it? If so how did it go?
Just try it. Worst case is they send it back
If you are lucky the bootloop gets fixed and they ask your if you want to get the screen replaced for some $$. (Don't know the real numbers but frontscreen should be around 50$)
And don't listen to the service staff. The repair team from LG decides if your phone is getting repaired.
Most common mistake by too much people.
I had the same problem with my Lg G4. I took it to AT&T Service Center and they wanted to replace it. However, I have important stuff saved on the phone. Do you think they can download or recover the data? Is it possible to do? I would think they know how, but just wondering if anyone knows for sure.

If you saved it to the sd card then you are fine. If not you can ask them if they can. I'm not sure if they would be able to or not

Severe brightness issue (screen largely unusable)

Hi all, I have a problem with my stock T-Mobile US S9. A few months ago this weird thing happened where if I turned on my screen immediately after it turned itself off, only the top few lines would be visible. The whole screen would take input, but you could only see a little below the status bar, maybe. If I waited a bit and then turned the screen on, it would work normally, with the whole screen visible and looking fine.
It's gotten progressively worse to the point where this happens most of the time I turn the screen on. However, I've found two workarounds:
1) My Always On Display is set to turn on when I tap the phone. If I do that, the AOD works as normal, and if I then turn on the phone screen the phone screen works fine. This only works when Always on display is set to turn on on tap. It does not work if AOD is set to always be on.
2) If, when my screen is glitching out I hold the screen up to a reeaally bright light (like inches from a lightbulb), the rest of the screen turns on. It's weirdly green tinted and kind of stuttery.
Turning off automatic brightness does not fix this issue. If tried booting in safe mode and even factory resetting the phone. Issue still persists, including on screens like when the phone enters recovery mode.
The fact that I can get the screen working normally using workaround #1 makes me think this is a software issue, but the fact that it happens on the recovery screen makes me think it's pretty low-level. Any ideas? Anyone else had a similar issue?
I gave Samsung tech support a call and the level 1 tech I spoke with seemed to think that it was a software issue and that I should bring it in to be looked at by a technician. I'm in Maine at the moment and there's no Samsung or UBreakIFix stores within two hours, so she suggested taking it to Best Buy to look at. Not amazingly helpful or surprising.
If it's a software issue though... I mean this is my fourth Android phone and I've rooted and flashed ROMs on all the previous phones anyway. I don't want to lose Samsung Pay, so I'd rather not unlock the bootloader, but is there a way to flash the stock operating system or something? The exact model number is SM-G960U
It's a firmware or hardware issue not software as a reload* would have fixed it.
The firmware has been corrupted (needs reflashed) or there's been a hardware failure.
Best to send it in for repair or take it the a Samsung Experience Center as they can reflash the stock rom and have advanced diagnostic tools.
*make sure all system apks are running on factory load and have not been updated after the reload.

If that’s really necessary I’ll do it. But the closest place is out of state and when I called them said it would take 4 hours just to do a diagnostic. That plus the round trip... if there’s a way I can save some time, I’d like to.
For example, if one possibility is a stock firmware reflash, that’s something I’ve never done before on a Samsung device, but not very different from things I feel comfortable doing. I've flashed roms and rooted many android devices in the past. From a preliminary search , it looks like there's even a leaked tool online to do so from Samsung called Odin and that I just need to find the latest SM-G960U image with the right "csc" code for my carrier (I think TMB for T Mobile US). What would be even better is if one of those diagnostic tools you mentioned leaked the same way that Odin did.
Any recommendations on either diagnostic software or firmware reflashing? Or would you strongly advise leaving that kind of thing alone? I would like to still use things like Samsung Pay at the end of all this.

If it's under warranty let Samsung deal with it. A good tech with experience is invaluable.
Rather then waste time the extra ride might end up being the easiest solution. You could also next or 2nd day it to the center and back, make sure it's insured and packaged well.

That makes complete sense for something under warranty, but unfortunately my phone isn't. The S9 is about three years old now, and the Samsung rep was quick to tell me that the device was no longer covered. It looks like a mail-in repair service would cost about $175, which I'm theoretically willing to pay, but not if I can just handle on my own for free.

In that case you have nothing to lose by reflashing it. Hopefully that gets it.
Otherwise it be hardware... probably a good chance this actually the cause.
The good news is the 9's are available for a couple hundred in good condition if need be.
I was considering getting the 9 as a second phone (have the 10+) as the 10+'s haven't come down much in price.
Samsung current lineup sucks.
Huh. Well, before reflashing, I tried something I found other people suggesting for a related problem: https://eu.community.samsung.com/t5...t-bars-black-screen-issue/td-p/1745470/page/7
It's an app called OLED Saver. It's not perfect, the screen still has an odd green tint to it unless I use one of the tricks I was describing above. But I no longer have the issue where most of the screen isn't visible.
I might try reflashing anyway, will post results if I do.
Yeah, no joy. Reflashed by downloading the latest firmware using Frija for SM-G960U with TMB as the CSC, and flashed using Odin v3.13.3. If anything the problem is slightly worse now, but OLED Saver still mostly seems to fix it. I guess it's just a hardware issue with a weird software workaround...
Same type of brightness problem here as you describe, on my new S9 (G960U) - - Model starqltesq - CSS XAA
The product is under guarantee, but as it is imported from Hongkong to France, I don't have accesss to the Samsung local representatives and have probably to send it back to Hongkong ...
I will keep you updated if I learn something about the problem and the solution ....
Wiping the cache partition stopped this happening for me for around 24 hours but it came back this morning. On the Note9 forums someone posted that setting animations to .5 in dev options fixes this. I will try it.

Disable animations instead. It wastes resources. Personally I like seeing a fast, snappy OS do it's thing with no middle man needed. Lol, you end up waiting for the animations rather than the OS.
I've heard of people flashing custom roms and that resolved the issue permenetly, but can't find anyone willing to give some real feedback. I posted a topic asking this question, but haven't gotten any replies..
Not very helpful, but a work around could be to use Screen Filter
I temporary fixing my S9+ green screen issue by uninstalling the NFC module.
Unfortunately, this option make us cant charging the phone.
Maybe some one expert in hardware mod can do better.

Hey could you explain what exactly did you uninstall and how?
After uninstalling it wireless charing stopped working or what did you mean by cant charge the phone?
Did it fully resolve the green screen issue?
Some people noticed that problem after upgrade Android 9 to 10.
At this moment we have some facts:
1) OLED saver temporary solves problem
2) disconnect NFC module solves problem, some people on xda and on the yt confirm that
3) heating back cover using heat gun can help - I Discovered that some weeks ago
Interesting comment from the yt:
Sour Words
Sorry to say this, but green screen issue is a hardware fault not something an update can fix. One of the updates from Samsung is causing the CPU to over heat and in return permanently damaging the oled screen. Not only that but also compromising the battery as well. The only fix is the replacement of both the oled screen and battery. This repair is entirely the fault of Samsung due to a faulty update that over works the CPU capacity. Therefore my advice is for you to return your device back to Samsung and lodge an assessment request. They charge a small fee for the assessment, but the entire repair should be compensated by Samsung. Be firm and keep the pressure via emailing them to insist on Samsung covering the repair costs. My Note 9 is almost 3 years old when green screen issue happened. They fixed the entire thing free of charge. But I kept firm and didn't let them bully me into charging me for the repairs, which was their fault in the first place. I must admit, my phone despite its age, is in perfect condition. Not a scratch on it. Which I know contributed winning my argument for the repairs. So if you have psychical damage, I doubt you will have a chance. Good luck to all who will give this successful method a go.
