Zenfone 2 Unresponsive Screen Problem? Help Guys.

Here's the video of my problem guys.
https://www.youtube.com/watch?v=i2DOknf_SJY&feature=youtu.be
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.

Touch freezing while receiving call from sim2
during I receive calls on SIM 2, the touch screen becomes non responsive for some time. It recovers after sometime. already 4 update gone still ASUS team unable to solve this problem,I also email 2 times regarding this issue no response from ASUS,this is fundamental feature of phone ,ASUS team give first priority to solve this issue ASAP

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 was using my phone..then it hanged..I cant use it anymore..the screen is still active..displaying the screen where it hanged...but its unresponsive..I cant do a thing....the power button is not working either..I cant even turn off my phone..and because we cant remove the battery on zenfone 2...how can turn it off?
pls help fast.

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.
And I am only using one SIM

G4 Bootloop

Hi Guys,
i am really confused and a little bit angry. The Following happened to me today:
My Phone (Unrooted, Locked BL) was behaving weird this morning.
It just randomly crashed and wouldn't boot up.
Eventually i got it to boot once or twice, but still it crashed, shut down and Bootloop.
A Reqular Factory Reset did nothing. now i'm trying to install the Regular KDZ-File for the H815, but things are just not working as expected.
Has anyone else had this problem before?
Is it normal that the LG Flash Tool is on 1% for over 5 Minutes and nothing changes on the Phone screen?
I want to know what has broken my phone so bad, cause this time, I just used it the way it was supposed to be used, no hard drops, no rooting, no changing of software in any means.
First LG Phone and it broke with no warning and no explenation. I'm a little disappointed right now.

Same
The same happened to mine. Are you able to get to download mode by powering off your phone and plugging it into your computer? Im able to flash stock ROMs but nothing helps. The phone reboots by itself at random times and makes it into the operating system a few times but is never usable.

Hey,
yes i can get into download mode.
I am able to flash files, but the phone wont boot up anymore.
I just want to save my data, but i guess i wont be able to do so.
So i have to get to the store and get a new g4
Luckily i made a backup of my two weeks ago, so not much will be lost.
I also send an email to the LG customer Service, will post their reply here too.
I am really disappointed by LG at this point, i usually had motorola phones and they didn't have random errors like this one.
I switched to LG, cause G4 sounded awesome, but this error is making me sad.
I am really thinking that i won't buy another LG Product, which is making me sad too, cause usually most things made by them are great.

//==============First Request by me:======================
Hello dear LG-Service Team,
i just bought the premium product LG-G4.
Since some days, the Phone is beginning to hang and reboot, resulting in a bootloop.
Sometimes the phone boots, than optimizing Android for about 30 minutes (100+ Apps installed). After this happened, i kann use it again, but not fully.
To shortcut eventual questions:
The Phone is in factory State, no Custom Rom installed. The bootloader is locked and the Phone has not been rooted.
The mistake seems to come from your firmware.
I am really disappointed, because i paid a lot of money and no have a product which is barely usable.
I switched to LG because of the G4 and i don't want to regret this decision.
Kind regards
<<Esok>>

Email and response, translated by me, so there might be some mistakes...
I don't like the response, it feels like not being taken seriously.
Well, nevertheless, i will go to the retailer and will see what happens.
I will keep you updated.
What do you think of this response?
Greetz Esok

That response is terrible lol. I called in and they said they do not support my phone because it is an international version. So there was nothing they could do for me.

I have a similiar issue, but mine was due to a OTA update, and I didn't know about the download mode until now.
Thanks.
Any tips when I can get into the download mode? I just wanna recover my personal data (images, and texts)? Flashing STOCK image would preserve the personal data right?

While your phone is off, plug it into your computer while holding volume up. If you are using LG flash tool to flash a .KDZ firmware file, you will come across an option that says Normal flash or CSE Flash. Normal flash will not wipe data, while CSE Flash will. I have flashed stock images and it didn't work. Hopefully it works for you though.

+1 I'm in same boat and exact same issue with my H815. I love the device but this is unacceptable.

I'm having the same problem, it just happened to me all of a sudden and now I can't even get to the boot animation. I've been able to get into recovery 2 or 3 times but usually it just restarts before it even gets there. I recently updated to the newest xposed framework (though I've restarted just fine a few times after I installed it), did anyone else here do the same?
When I get home from work I'm going to keep attempting to fix it, I've flashed my current TOT but it failed after rebooting. I don't know if I'm having the same problem as everyone else but I'll update if I can find a solution.

same issue here on the at&t 810. Starting about 3 days ago I started getting random reboots + bootloops. Sometimes it would boot to the LG logo and stick, sometimes to the AT&T logo and stick, sometimes to the OS and freeze after the lock screen appeared. I can get into the OS and use it for awhile, then it will restart and it all begins again. 2 factory resets so far and no dice. I am rooted on 10e but have a warranty device on the way which undoubtedly will be on a higher firmware and will likely miss out on the potential coming bootloader unlock. At this point I am probably going to sell on craigslist and get a 6p. The phone is great when it works and I love the size, the looks, and the screen, but the lag and these reboots are unacceptable.

Just a short update by me:
I gave it to the retailer, they said it would take about 10 Days.
I hope this stuff won't happen again or this was the last time i am buying a LG Product.
I think i would have been better off by sending it directly to LG but nevertheless, maybe giving it to the retailer will make my warranty stay longer
I will keep you updated, including firmware Version the phone has after sending it in and so on.

All of the sudden my phone today just froze leaving me with a black background and no animations, the phone is very hot if I try to use it on that moment. Even when I reboot the phone stays very very slow and says system it's no responding.
What can I do? Even when a Reboot it some times works normal then suddenly does it again.

Sounds like a heat problem in your case.
What happens if you pull out the battery, wait 10 minutes to let the phone get cold and than reboot?

Well, no luck on my end. I could only even get into recovery one out of every 50 times or so that I tried, and when I managed to I wasn't able to sideload any system software because it wouldn't initialize the driver (my computer recognized the phone just fine, except the ADB portion). Clearing the data did nothing either. Luckily I'm on Sprint and the phone's being recalled anyway, so I just walked in and they swapped it no questions asked. At least after flashing a TOT and clearing the data they shouldn't have an easy way to tell I was rooted or anything.

Thanks for replying, I completely restored phone today and was a success. No more black background.

same random rebooting issue here as well. and I just bought this phone brand new from a 3rd party :/
Update: I seem to have gotten past the problems after updating to 10n. Now running stock debloated 10n rom with no reboot issues (so far)
Update 2: Had 1 - 2 cycle bootloop on 10n

I don't see how you giving your phone to your retailer will extend your warranty. That makes absolutely no sense, since your warranty begins from your date of purchase.
My phone also ended up with the bootloop and having to exchange with a new unit. I'm on the TMO Variant H811.

Actually German Law is a little bit different.
Regular warranty is not what i meant in my post, i meant the "Gewährleistung" its an additional kind of warranty given out by the retailer.
There are some cases in which this "Gewährleistung", which usually lasts for about 2 Years is made longer. Mostly this happens when the retailer would have to send in a product for the third time, they basically give out a new one, which will be treated like a NEW device. So new Warranty, new "Gewährleistung".
I hope this somehow made sense

Today i got my phone back.
They repaired it.
Everything is like it was before, so i am pretty sure they didn't change it.
Firmware Version is 10d.
The Phone is working so far.
Will keep you updated if anything changes.

Random Reboots?

I was just wondering if anyone else has an issue with their Note 4 rebooting randomly with no external input. This started happening with the Android 6.0 update both on the download from here and the AT&T official release, Any Ideas? I've already purchased a new battery due to a separate issue, any idea?

I had the same problem. The phone would freeze and randomly reboot. Sometimes the system crashes and asked me for the typed-in password (not fingerprint). Sometimes when I charge the phone, and unplug the power cable, the charging led stays lit and the battery has to be pulled. I decided to switch the battery with my wife's Note 4 and see if the effects remained. So far I haven't had any problems after switching the battery, so I believe the battery may be the cause of all these issues. I'll keep you updated on the issues.

I'm back. The battery replacement didn't fix the reboots. I think my phone's hardware is permanently damaged. :crying:

can you downgrade to Android 5.0.1 and help me with my problem?
its something completely different to this topic

I've been having the same issue, started about 2 weeks ago. phone would start being sluggish then if I continue tapping on screen, it'll reboot. At least once I saw it go into recovery & reinstall firmware(?). Another time it just sat at the bootloader screen waiting for software download or something till I took out the battery. Most likely it's a software issue related to 6.0 update or updates afterwards. taking out the SD card helped a bit.
but basically got annoyed & upgraded to LG V20 today. Coincidentally, there was another person at the AT&T store with a Note 4 having the same issue.

Mine just rebooted twice on me a while ago, first is emergency calls only now the reboots then what. And yes the slow charging is a problem too. MM got serious issue dam att

use wakelock its an app u get it from play store.it makes ur cpu always running.some how it fixes the problem of random reboots. dl it and set it to partial lock (the 5th option)

Same problem. Just started a few weeks ago. REALLY frustrating having to enter my password every 3-4 minutes. NEVER buying another Samsung, too many damn issues with this phone.

My reboots tend to happen once the phone goes below 60% battery. It's fine above 60%. Once it goes below 50%, the reboots tend to happen with any intense network activity. The phone will often go from 50% to 22%. I forgot what the 30's and 40's look like. I will try the Wakelock app.

Ugh. I posted about this a few weeks ago. It's started happening more frequently and will occasionally go into a boot loop or show 0% battery even though there's a charge.
Has anyone found any solution? I haven't tried wiping / resetting but I'm getting close to trying it.

Here is a cautionary tale for you. My completely stock, unroooted phone started acting the same exact way. On the 4th or 5th battery pull (to fix a frozen screen) it just crapped out. It's totally unresponsive. Deader than a door nail. Tried everything. The download mode, discharging by power button depression/battery removal, etc. Adb shell command does not detect it. Nor Odin. Computer throws up a qhsusb_bulk error when I plug it into pc. I have NO CLUE how to fix it & I am desperately seeking a solution. Please proceed wisely with your oddly acting phones & don't let this happen to you.

Same issue. Just got off the phone with Samsung support, all possibility of having this particular phone with this particular issue sent in for evaluation has been suspended. Translation, they know it is an issue and will not stand by the changes they push to their products (latest OS). I am researching the prospect of legal action since THEY pushed the new OS against my request. Shouldn't that affect the warranty or coverage? Consulting my attorney friends as we speak. Will let you know. I am not sure how WakeLock will help, it is not going to sleep, it is repeatedly power cycling through a kernel process until the battery overheats or it reboots.

Same issue
Since Marshmallow, my 910A will get sluggish or freeze, shut down, sometimes reboot and sometimes just brick (temporarily). Sometimes--more often in recent days, I get a "dll_mmc read fail" message and the target that says do not stop downloading. No matter what I've tried--factory and soft resets, cache clearing, battery pull, replacement, and SD card switch, contacting AT&T and Samsung rep--it doesn't seem to change. This is a daily issue and becoming more frequent. Any suggestions or do I just need a new phone? Thank you.

Galaxy A5 2017 crashes and reboots when in standby

Hi there,
as you can read in the title, my Galaxy A5 2017 (SM-A520F) started behaving weirdly yesterday.
When using the device it shows no problems at all and behaves as expected.
But everytime I put the device into standby it reboots or crashes after 20 seconds or so.
I have not modified my device software in any way, not even rooted it.
My temporary solution has been to install a WakeLock app, which seems to keep the device from rebooting.
However I don't think this is the best solution, especially because it drains battery life more than necessary.
If anyone has any solutions or suggestions that would be great.
Thank you very much in advance.

I already tried all of that. Not even a full factory reset could help. I guess the only thing left is to replace the phone :/

I got the exact same problem, I sent my phone to get it fixed.
I'll post the solution asap!

I have the same problem. Sometimes it reboots twice a day, sometimes it is ok for a week.

Same exact problem over here. Glad I'm not the only one.

It doesn't seem like it's a software issue, so there's nothing we can do about it. Just go to the store where you bought it, they will then send it to Samsung to have it repaired. If you still have your warranty it won't even cost anything. They repaired my phone in 5 days and I'm happy to report that it's now fully working again.

The Root of the problem is the fingerprint scanner, i just desactivated it and now it's fix... The fingerprint scanner is kinda broke :/ i Saw that this problem appairs on nexus 5 in 2015...

OnePlus 3 issues

I'm having the following issues with my OnePlus 3 (stock recovery, no root):
15 November: last known date without any issues
16-18 November: when I played games I noticed that screen won't rotate even when auto rotate was ON
19 November: I wanted to click some pictures when the camera app just stopped working
Tried rebooting and clearing cache, but didn't work
Thought a software update might fix these problems
20-27 November: when I answered calls the screen won't turn off. That's when I realized that all the sensors on the phone had stopped working (no lift up display, motion sensors,etc). Read online that I could get the official Oreo update just by changing my VPN to Germany/Canada. So I did the same and upgraded to Oreo
Still the issues were there and battery drain was significant. The phone would reboot on its own.
On contacting OnePlus support they asked me to do a hard reset which seemed to work only for 3-4 days
28-29 November: the sensors stopped working again & again and I did a hard reset every time
In the end the phone switched off and the white notification light was on continuously. Pressing or holding the power button didn't work. Contacted support
2 December: through a remote session the OnePlus support installed Oreo again and on rebooting I got DM-VERITY error. So the support asked me to visit a Service Centre
3 December: I visited the SC where they concluded it was a hardware issue (motherboard: 17000/-) so I asked them to just roll back to OOS 4.5.1. Worked fine for 10-11 days
14 December: started rebooting randomly. Noticed that the phone would hang and reboot when using the camera (in WhatsApp, CamScanner and stock camera), maybe I'm wrong.
So now there's minimal usage of a phone with such high capabilities knowing that I'll have to do a hard reset once a week.
How can it be a hardware issue if the phone works fine for 4-5 days after a hard reset before breaking down again? What does that white notification light mean? Any help would be greatly appreciated

"3 December: I visited the SC where they concluded it was a hardware issue (motherboard: 17000/-) so I asked them to just roll back to OOS 4.5.1. Worked fine for 10-11 days"
There is your answer, there is a problem with you motherboard, you need to get it replaced, we cant diagnose a hardware problem here!

How come it works normally for a week or more if there's a problem with the motherboard?
And a hard reset seems to return the phone to its normal state.

That just means that it is faulty and will fail after some time. This most likely means there is a bad memory sector on the board. As suggested. Get it replaced or you will keep having these issues.

Okay. Thanks for clarifying.
May I know what may be the causes for the motherboard damage? How common is it that a motherboard malfunctions?
Because there was no physical damage at all. Thanks again!

See that is the thing. China has no real quality control standards. So it could just have been a bad board. If you look around you will see that a range of random issues seem to pop up over a short time. Yet some are just fine. Like mine. It had a faulty USB port from day one to the point that I knew it was gonna fail. (expected) So I am replacing it.
