Screen flicker problem - ZenFone 2 Q&A, Help & Troubleshooting

Since 2 days ago, I'm having a screen flicker problem with my Zenfone 2 551ML. At times, the lower part of the screen flickers. It happens when I scroll menus, webpages, basically when I move the screen in some way. This stops if I leave the phone in standby and after that I use it again, but after some time, it reappears.
I read somewhere (forgot if it was on this forum or on Zentalk) that disabling HW overlay in developer option can stop this kind of screen flickering, tried that and it worked.
1. Is it okay to leave it like that? What does that option exactly do? Will it affect the device performance/my experience with the device?
2. I tried wiping cache in recovery mode but it didn't help, the problem came back after a while. What kind of issue do you think this is? Hardware? Software?

did you ever get this resolved?

Stock Tab 3 - Screen Flickers

I just recently got a T217S from Sprint, had it about 2 weeks, running all stock, 4.42 Android. Ran fine the first week, then I noticed that the screen would start to flicker. Doesn't change colors, just flickers. Playing with the brightness can sometimes cause it to stop temporarily, but it starts again almost immediately. The level of brightness doesn't make a difference, neither does any applications I'm running. I've rebooted it into safe mode and without even touching it, it started flickering less than 30 seconds after booting. I've google the heck out of this and it doesn't seem to be a hardware issue, but an Android problem. I would like to avoid a factor reset if I can, especially until I get solid proof that it would FIX the problem. So far, no one can even tell me WHY it's doing it.
HELP???

Screen and the capacitive buttons isn't responding to touch although the screen is active and working. This always happens every 10 minutes. Really need your help guys.
What do you think is the problem? Is this a faulty Zenfone 2? This is not rooted. Using Stock ROM with latest update. I'm currently doing a factory reset. Will update later. Thanks
I had a problem with my phone not waking up, had to get a replacement.. so far the new one is flawless.

I got the same problem as you, seems to be something you downloaded. I did a factory reset through the settings and it got rid of the problem.

Hopefully. I tried factory resetting the phone. Screen is not being unresponsive so far.
If problem continues, recommend performing a hardware reset including wipe cache partition. For hardware reset/wipe cache partition instructions please see the following: http://www.asus.com/us/support/FAQ/1011956/

I got this solved. It seems there is an error on the sim 2 tray.. The screen being unresponsive only happens if there's a text from sim 2 or a call from sim 2. Its not always happening but its really annoying if it happens since you have to wait for minutes in order for the screen to work again or you have to turn phone off. Now I only use sim 1 tray and never experienced the problem anymore.
This looks like a software bug as many users are complaining about this in asus zentalk forums.

Hello. I'm currently having the same problem with my zenfone 2, but I don't understand... how do you 'factory reset' the phone?
And is there any other way to fix this problem other than resetting the phone?
Read #6 post, even factory resetting could not solve the unresponsive touch screen issue. If you want no screen issues, dont use the sim 2. Try setting your mind that zenphone only uses 1 sim. Haha. Only use sim 1. You'll have no problem on unresponsive screen everytime there's a call or message coming from sim 2. Asus has yet to release a software fix for this as many are encountering this problem

I hope Asus fixes this problem real soon.
So, so far there is really no way to fix this yet? Because anyway, I'm not even using sim 2. Now what do I do...
I am also facing screen freezing issue due to SIM2 in my Zenfone2. I did a factory reset and the problem still persists. Is it that the phone is not suitable for dual SIM. Either it unfreezes after a min or so I had to hard boot it since the restart option on touch screen is not working. Phone per say is never frozen except the screen.
Can anyone suggest a solution on this forum
Touch freez issue on incoming call on sim 2
Having the same touch freez issue since i changed my sim 2...
Temporarily i am using zenmotion "hands up" feature to pick calls....
Waiting for asus to resolve the issue...
Touch freez issue
accidentally my screen got cracked, so i replaced the display. Now no more touch freez...
I think its a hardware related issue....
cm
This only happens to me with CM (12 and 13), not using SIM2 is not an option for me, so I'm stuck with stock rom.
I had this problem with the Asus Zenfone 2 View Flip cover. I removed the cover and the problem didn't repeat. So suspect something with the View Flip Cover app which causes the screen to freeze.
I'm having Ghost touch issues and screen becoming unresponsive before the ghost touches start to occur. I'm pretty sure that this is a hardware issue.. I've been able to fix the problem by turning off the phone and tossing it into the freezer for a few hours.
I'm going to re-flash stock rom and RMA and hope they actually fix the issue since it's intermittent.
I returned the phone for RMA last Friday and got it it back today.
I gave a detailed description of the issue on the rma form and they replaced the screen and so far it looks good. (I can tell it was swapped since some cosmetic damage on the lcd plastic bezel is gone)
Guess I'll give it a few days of normal usage to be 100% certain,but so far I can notice some touch response is better than the old screen too.
On a custom recovery / unlocked bootloader note (unofficial method)
Fortunately flashing back to stock was good enough and they didn't just send the phone back as an excuse.
I'm actually super impressed with the Asus rma process, and reckon the bad digitizers are a widespread and known issue since they replaced the screen so quickly and without hassle.
I'll definitely keep Asus as my hardware provider when I upgrade to my next phone and tablet!
guys.. i need help

I am also facing the same problem from last two weeks after upgrading the phone to latest firmware update. I tried factory reset, cleared cache bit nothing worked. In case the screen is not responsive then I have to switch of the screen by physical button at top to unnlock sometimes I do this 2 or 3 times to get the phone working again.

my pixel c gone mad

Hi all,
I've recently got this tablet from Google store (and out of stock now).
After installed all things needed, a serious problem has appeared during in use. Its screen unexpectly trembles, pops notification out, runs and closes apps randomly then unable touchscreen at all. These make me crazy even in screen saver, and power button doesn't work sometimes to stop those happenings.
The device hasn't rooted and staying as 'pure' with only afew apps, so I've done erasing system cache partition on recovery mode and factory reset twice to solve this problem.
Nothing happened so far since reset the device but is still unsettling.. and now I just supposed touching screen badly (with sweaty fingers for example) or the screen protect film I affixed since unboxing might cause the problem.
Does anyone faces a problem like this?
Regards,
Allen
If it was greasy fingers my tablet would be completely unusable. Luckily a quick clean sorts any issues that causes.
My first suspicion would be the screen protector, as mine has done similar when there was something touching the screen. Maybe try taking it off and seeing how it goes? You can also turn on show taps in the Developer Options to be able to see what touches the tablet is detecting when it goes mad.
Better than before

Thanks for your reply. Now I've used a BT mouse to match with mine and less touch on the screen apparently. Nothing happened so far.
It's not a problem of hardware I supposed and pretty sure that the screen protector interferes a certain touch as you commented. Still my eyes are keeping on what caused the problem.

have to tap with two fingers to use touch screen

Recently i have replaced my touch screen folder. But after that everything was working fine but after encryption, the problem of tap anything on screen with two fingers arises.
In the bootup of the phone, when I enter my encryption key for the storage, I don't have this problem at all. So it must be a software problem. It only shows up inside roms after encryption (every rom).
i have also encrypted before screen replacement but none of this issue happened.
anyone plz help me with this issue
or send me anything to activate fingerprint without encryption on Oreo roms
Similar issue here and I saw that a lot of people encounter issue with touchscreen responsiveness after having changed their screen.
Here are my symptoms :
Most of the time, if screen is left idle for a few seconds (still lit), it needs to be woke up by 2 fingers or a large finger (thumb) of a 2 or 3 single finger taps before being fully responsive again...
The phone stays responsive as long as it is used.
Problem DOES NOT occur in recovery. So it is software related I guess...
I read all comments linked to the screen I bought on Aliexpress (screen was tagged as Original, I could not find any difference having both screen in hands, so it clearly is from the same factory)
One comment stated to do a factory reset if the touch screen was laggy...
But maybe this factory reset must be done on stock rom ?
I also wondered if a kernel could have some specific option regarding touchscreen behavior that could help...

Phone crash only when locking phone

Hi guys,
I am having a very strange issue with my Pixel 2XL, being that the phone will crash whenever I lock it and leave it for 3 seconds or more. Any less and I can unlock the phone again just fine. Also I tried playing some music through chrome and locking the phone, which carried on playing for 20 minutes and I could unlock the phone again with no issues. It gets stuck on the ambient display with the time when the phone crashes and I have to restart it (With power and volume + buttons).
I have tried to factory reset and even flash older factory images (I am by no means an expert and just gave it a try).
As of now I am out of ideas as to what it can be. I can only assume that a service or something is in standby and is causing an error when it goes to ambient/standby. I have also tried to change all settings in battery optimisation to not optimised, which did nothing.
Has anyone else had a similar issue and know how to fix it.
TIA!!
The same with me
Hi My Pixel 2 XL has exactly the same issue. Have you found any fixing method? Thank you:crying:
