Unresponsive and Crazy touchscreen

Received my phone yesterday, and when I was browsing it , the screen went crazy, and unresponsive. did a factory reset and the problem still persisted. Opened a return request at amazon so they can send me a new one. Don't know if anyone had the same issue or it was just me. Here is a video
https://dl.dropboxusercontent.com/u/12983778/VID_20150527_213832648.mp4

Please check if TalkBack is enabled. If this setting is enabled, the touch screen may behave differently and appear to be defective. Instead of one tap to open an item, you will need to tap once until it highlights with a green box around the selection, then double tap to open. Also when swiping it may require using two fingers instead of one. You may also be hearing voice prompts to every action made.
To disable go to Apps/Settings/Accessibility/Talkback - turn off.
Best regards,

Same problem
Hi,
I had the same issue! I getback the phone in guarantee to Taiwán. The seller says that the phone was repairde, the display was changed.... finally 2 weeks ago I reicived the Zenphone 2 (1.5moths since the deal). Now today the phone have the same issue, I try to clean the dipslay phone and suddenly the touch screen have the same issue, crazy and unresponsive screen!! I very frustaded about the ASUS Brand! tell me what's happened with your phone?
thanks
Xytrax

Try to delete user data,then factory reset and then wipe cache.If after this you're still in trouble simply use warranty:hardware problem,asus fault.

You must use 2 fingers when you type to get through the setup. I know its a pain but when you are able to get in, turn "TalkBack" off.

I bought a zenfone 2 64gb on amazon and I had the same random issues: unresponsive touch screen, unsensitive, ghost touches.
I guessed that it could be the screen protector but it was still happening after remove it.
So, I asked to amazon a replacement.
After a perfect week, I am starting to have the issues, again!
I sold my oneples one to avoid touch screen issues. I am very upset!

I'm having the same issue as you guys. I also noticed that cleaning the screen with a rag (especially the one for glasses) makes the touch screen go crazy. At first i tried to downgrade the firmware, unluckily i had the issue again. Then i upgraded the firmware from the phone and now it's all going apparently well. I'll update for any news.

Same here, wrote to customer care yesterday evening.

Please let us know if you have any answer, it is getting very annoying, thanks.

To anyone who have this issue: Try to test touch screen by SMMI's test option. Open calculator, type ",12345+" (with the comma), then "=" (equals). SMMI menu will show up. Now "single test", then "touch test".
In my case this process gives a straight line of unwanted touch inputs in the upper region of the screen ( sometimes multiple dots in a row forming a complete straight line). Do you guys have the same result?

With the others, I have this one, also. It happens at every restart and the only workaround is turn off/on the display.

Same as me.. But I think this is lcd controller firmware or driver problem on kernel . because yesterday I'm install custom rom on my zenfone (Cm12.1) then surprise ... this problem continue... I had change custom kernel but no chance ... if you have this problem open Asus glove mode this is temporarily solution for now. Asus will contuniue work on this problem. Now I waiting Asus response for this .. :

It's a software related problem.. Because we're a lot of ppl suffering this problem. But, don't know why, ASUS is ignoring us.

I have sent my phone for repair. They say that they will replace the whole display.

Hi guys. I have almost identical issue and this seems like a hardware fault. I sold the Zenfone 2 to a friend and after 2 months she complains about the unresponsive touchscreen only at the top of the display..... I have the phone with me now, trying to fix it.. Did a factory reset, firmware upgrade, no results. Definitely a hardware issue and it is seems that lots of people are affected. So dissapointed by Asus......

If it's a hardware issue why is it so many people experiencing this now together all in the same time? Not earlier not later? My guess will be software problem. But I'm not sure

Any of you guys have a microsd card installed?

Hey everyone, thank you so much for sharing with me. I'll forward this to our service team. Sorry been away..it's Thanksgiving week here in the US...so I'll get to this on Monday!

Anyone notice bugs since last OTA patch?

I've been having issues with touch responsiveness off and on for the last two weeks or so, and I'm wondering if somehow the last security patch could have caused it. Like, I will be typing with the swipe and it will stop halfway through a word and spit out random stuff, or sometimes I have to pull a few times to bring down my notification bar

Everything's ok for me. Are you using a glass protector?

No such issue here either, I don't use a screen protection.

I am using a glass screen protector, but I've had it since I had the phone

I'm having the same issue. And of course, it's not doing it now as i swipe. Happens more when i type.

I have noticed something similar. My issues has been like this since I got the phone and upgraded to 8.1. I heard of others also making this complaint after the fist update to 8.1.
For me... When I try to silence a call it will not let me swipe down on the end button. Unlocking can also be a challenge.

I use a pattern and sometimes getting to that can be an issue.

The only problem I've noticed, and I'm not positive this is from the OTA, my Gear S3 stopped vibrating and showing notifications from Android Messages. It was literally the day or the day after I took the OTA. But, who knows. All other SMS apps seem to work fine though.

I still haven't unlocked and rooted mine yet, so I'm hoping by doing so maybe this issue will disappear. Lol at least it doesn't seem to be just me. Though I'm glad to have this issue and not one of the other, worse issues I've heard of people having ?

I'm unlocked with root...

I have screen touch issues. Answering or declining a call is frustrating.

I get it still when I try to swipe away a notification or if i'm pulling down the Notification shade to access the quick toggles, it goes up and i gotta pull it down like 4 times to get it to stay

Yeah I've noticed this as well, have issues answering and rejecting calls and typing on the phone the touch screen responsiveness is off. Hopefully they fix this and the battery drain issue in the March update, because you know we wont get an update before March 5th lol. Also noticed my Gear S3 doesn't receive notifications properly anymore, tried factory resetting the watch and the phone and no resolution unfortunately.

I noticed this both on factory 8.1 image AND on DU RC22 Rom.
Once in a great while, usually when playing a game, I have to tap twice to get a recognized touch, especially near the edges.

Mate 20 X Unresponsive Screen

Hello guys!
I have bought a brand new Mate 20 X just 3 days ago!
I noticed that some times I click something and it wont do anything or do it with delay and sometimes I click on something and it vibrates like it did it but nothing happened (like home button for example).
Does anyone else face this issue? do you know how to fix it?
Have a great day!

Nothing here, I also use the gestures so never use the home button. Is it specific apps that cause issues or just in general?

Yep, it happens to me quite frequently. I don't think it has anything to do with the screen though. Do you have a nano memory card? Are you stock? What apps have you installed? What browser do you use? Mine started doing it after the 192 update (I think) and has been doing it ever since whether I'm on stock or on a custom rom. You'll tap a program and see that it selected but sometimes it takes like five to ten seconds to open.

sometimes when I touch with 2 fingers to zoom (for example on a document) it just stays on zoom mode even when I touch with 1 finger (so when I try to move around it will change the size like a 2 fingers gesture).
scrolling is way slower than any other phone I tested, has anyone else noticed that?

Take screen protector off and clean it might be smudged . Maybe you could try glove mode it's more sensitive in settings

tried both, didnt help.

I thought I was the only one with this issue.
After flashing the Resurrection Remix rom I have never encountered this problem.
I'll be going back to stock soon so I'll see if the problem still exists.

Mine works perfectly. Even with the protective film scratched. Worked perfectly with my previous screen protector, a tempered glass type. I have the chinese EVR-TL00 midnight blue model. Everything stock, no root.

I also have this problem
You're not alone, this is happening to me as well on the EVR-L29. In my experience it is most noticeable when tap typing and a letter I tapped on does not register. Also, once in a while when I tap on an app to open it nothing happens and I'll have to tap it again for it to open. It's a mild annoyance for me, but not to the point of ruining the experience. I'm hoping a future software update addresses this, unless it's hardware related. I love the phone, but this is probably my biggest gripe outside of the possibility of no future upgrades in Huawei's spat with the US.

Lock Screen unlocking problem guys, screen is unresponsive for 3 seconds.

after each lock when i turn the screen on with double tap or power button screen is unresponsive for good 3 seconds. This started happening after the latest camera fix update. When if i use aod and use the fingerprint through the aod this doesnt happen. tried reboot and factory reset with fresh install (no backups) tried safe mode. Same thing happens.
S20 plus exynos.

Yup happening to me too (s20+ exynos). For me the time of unresponsiveness is around 1-2 seconds. Happened after the latest update.

Yes, have been facing the same issue since "ATCH" update.

Yeah has been driving me nuts. Same problem.

I'm surprised this isn't gaining more traction? Can't be the only few experiencing this!?

Glad to see it's not only my device. Waiting for fix.

I have similar situation

I'ne noticed the same after the last update.

There is an app called samsung member where you can send error reports. I have already done it, its currently under review. I suggest everyone affected to do it.

Seems like a pertaining issue for Note 10 Users too. They found a trick and seems it works better now. Can you try this and let me know if it works better?
turn off the battery optimized for apps: com.samsung.android.biometric.
Go to Settings>Apps>Select "Special Access" from three dot menu>Optimise Battery Usage>select All from drop down menu>Search for "com.samsung.android.biometric"> Turn it off and Restart.

I did this already and while it feels like fingerprint is faster, unfortunately this is a screen issue. You see if the screen is off and i put the finger in the correct spot it always scans my finger without any lag. The issue is occurs when -
a) I have unlocked the phone using above way, then the screen becomes unresponsive right after unlocking.
b) The screen is off and i either press the power button or double tap to wake, then the screen will be unresponsive and its during this time the fingerprint scanner doesn't scan (because the scanner doesn't know it needs to scan since the touch is unresponsive)
so TL;DR its not a FP scanner issue.

I am quiet sure Samsung is already addressing this issue for next update.

Question Touch Screen Problem!

hello everyone,
I just bought z fold 3 a few days ago,
after hours of working with I found that sometimes the touch screen(inner display) doesn't respond,
for example, some words don't type when I am typing quickly with the keyboard (just sometimes)
factory data reset didn't help.
has anyone run into the same problem? may be resolved with future updates?

Is it only happening to apps connected to the internet ie is it a connection issue?
The internet's been goofed up in some areas the last few days. Try toggling the airplane mode off/on.
Keep power management disabled for now.
Does it happen in safe mode?
Find the factory test settings for the touch display, test (and calibrate if needed/possible).
If you can't resolve it, return it. Otherwise eyeball every square inch of it like a hawk...

I tested the touchscreen with *#0*# and everything is fine.
just sometimes this problem occurs and I think this may be software problems...
have you z fold 3?

No. Basic troubleshooting.
Samsung will likely release firmware updates to correct this if enough devices are effected. It may be a 3rd party app causing this... try in safe mode. Disable animations for now and see what its got.
I stopped at the N10+/Android 10 and will likely stay in this holding pattern for at least 2 years.
I have two now and they run close to flawlessly.
Both Samsung and Android are having major issues, plus I require a SD card slot. Even issues on the N20U, which helped nix it from my list.
It may be a good year for Fold fans but otherwise both Android and Samsung have dropped the ball and are in a flat spin... in my opinion.

my problem is just like what you see in this youtube video in Time 12:15 and 12:49 . I must double try some times to click some things. this is very annoying on the keyboard and when you are typing quickly.

If stateside you can go to a Best Buy that has a Samsung Experience store. They can do advanced testing on it... allegedly.
I would get it resolved soon or return it for a complete refund.

I tested the touch screen with "touch screen test" Application and uploaded a video on youtube, you can see here.

It looks fine to me... do you mean latency time?
What are power settings at? Try bumping it up to maximum performance.
Check ram usage.

Is there anyone here with z fold 3 and the same problem?!!!

I only face this problem when I touch the edge of the display with my palm.

I tried to replicate the issue. I downloaded the same app on my Fold 3. I tried for few minutes.
On my device every click is registered. No missing dots.

I have the exact same issue. I addressed it by increasing the screen sensitivity.

Hey, I just noticed it today as well. When I try to type text faster, sometimes I need to double click on letters. I think this problem came with the latest update, because I havent had that problem before. It is frustrating.
I tried to turn on sensitivity option in settings and I will reply here after day or two testing.
seems to be a bit better with that option turned on
