[Q] Touchscreen gone mad @lockscreen

Hi!
Have anyone notised this problem with Z1C?
I received my Z1C 4 days ago and this has happened once every day. It seems to appear when trying to unlock the phone and all of a sudden it goes mad and nothing seems to happen when touching the screen. Otherwise the device seems to work fine. But do you guys think this is a software issue that can be fixed at next update or do you think I need to RMA?
regards.

This looks like a software issue to me... Try to factory reset your device and if it still persist reflash it with PC Companion it should fix the issue. A hardware defect can't make a phone like that don't worry

did it do that right out the box? or did you install anything that could have messed with that?

I cannot se anykind of app that I installed that would mess up the device like that? Ive installed about 15 apps and mostly "stand alone" apps like skype, sofascore and MX player. The app that closest could affect the UI is then maybe Nova launcher (got the prime verision) but I dont think it would mess up the lockscreen like that? (Or atleast it havent on any of my other devices, always felt solid and worked perfect)

It's not always about apps you installed though... There could be data files from system apps that got corrupted and caused the issue.

Do you have glove mode on at all? The screen is very sensitive, it could be some conductive dirt on the screen. I tested my Z1C in the shower, a drop of water rolling down the screen is enough to open the notification area or scroll a website in chrome.

Did you see this?

I think this is a hardware issue.
This happens more often if you use some sort of flip case (I had roxfit).
Now I have only a screen protector with hardcase i have still lockscreen ghost touches but less.
To fix it just clean the display with cloths or something you prefer.

Okay, this is starting to be interesting. I actually did a factory reset three days ago and now this phenomenon haven't happened since before the reset. Though I must admit that Im not sure if I noticed the problem before mounting the Muvit Easy Folio case since I got the case the day after I got the phone. Unfortunately I have not had time to reinstall all apps that I had before the factory reset so for now my phone is not really comparable with the device it was three days ago. After the weekend I will probably know more since I will have had more time testing and installing all the former apps (then I can uncheck that variable). I hope its not the case since I have not found any other case that's lime and also cover the screen, though It also looks like a possible troublemaker (according to delimanyak23 and the thread)
time will show, I'll be back when Ive done some more research

This happened to me but in homescreen. I just turned off the screen. Wipe the screen with my tshirt for 2-3 secs and viola problem gone. Weird but it works

My wife also has that issue. Her phone was factory reset but still the same and as it was seen by the shop who sold it to us, the phone will be replaced today. We will see if it happens with the new phone.
Nb : glove mode is off, no screen-protection used, a protectiln case is used but i don't know what model it is. I'll you the update after trsting the new phone.

LG G4 Touch Screen issues. Ghost Touches?

I've been able to replicate this issue on my G4 (815T Australian model) on a daily basis, just on the instagram app though.
I recorded a video of it. Slowmo part shows the issue
https://goo.gl/photos/F823e125PQckCPLp6
The screen seems confused and it just scrolls the other way even if my thumb wasn't touching the screen.
Factory data reset did not fix anything.
Are you able to replicate this LG G4 owners?

I don't use Instagram, so can't help with that app, sorry.
But if you go into Developer Options, and turn on "Show touch data", it might help add some more info to the discussion. It will show a trace on the screen of what the phone's touchscreen interpreted from your last tap/swipe.
It would presumably show a swipe up, and then back down, when you're getting these ghost touches that change the scroll direction. But perhaps it could also help show if swipes are interpreted the same way in other apps. It might help you learn a little more about what the phone is seeing, at least.

Thanks for the video and everything but why a new thread? Plenty of videos on the main thread.
Is another thread really necessary?

Might be, because this only happens with IG. I've got the exact same problem, only with IG and its very annoying.

You can try to change the touch feedback time from short to medium under settings/accessibility/motor & cogination. This will reduce the touch feedback time. Give it a try, and see if it gets better.

Well this problem is only related to the LG G4 and IG for me...I don't have any other touchscreen problems with this phone. So for me I guess this is not hardware related. During the day I just had 2 small "ghost touches", way better than before. Will see how it goes the next few days...
Edit :
after a view days, it looks like it didn't solve this issue. Today I notice the ghost touches were there again in IG

Force GPU rendening under Developer options somewhat helped.
The new v10f on my Australian G4 didn't fix the issue as well.

Any updates on this? I had same issue. N this is a replacement unit after 2.5 weeks of waiting
Just day one and this ghost touch come up.

I also have this problem
Did you solve the problem?

I am facing similar issue.between...i am not using ig.

I've had this issue as well (not just IG) and sent the phone back for servicing. It was sent back to me with a report showing that they'd done a few things but the problem is still there. I'd been thinking I'd send it back in once more and ask them to have another look. I'm getting ghost touches everywhere and quite a bit, it's very annoying.
Someone mentioned there was another, large thread about this issue but I can't seem to find it, can anyone point me to it?

Hi, I posted this in a new thread yesterday as I couldn't find anything. Never thought to search for 'ghost taps' duh.
Every now and then when just doing normal things on the my phone it totally freaks out and all by it self it suddenly starts to tap random parts of the desktop, slides the pages, opens apps, closes apps, goes into calculator and a bunch of buttons are pressed randomly. It's almost like someone has hacked my phone and is trolling me by just tapping randomly on the phone.
Just today when looking at Facebook it closed the app, scrolled down notifications, data was turned off and wifi turned on.
I thought it might have been my screeen protector, bit of moisture in it or something. Took that off and still does it. Took out the battery for a minute and still does it.
It happened a few months ago then nothing for ages and now it's started again this weekend.
Thought it might have been only when connected to data but has now done it when offline.
Any one got a solution? Does a custom rom fix?

Fingerprint scanner randomly not working

I'm just trying to narrow down why randomly the fingerprint scanner does not wake the phone. It might happen once a day or not for a couple of days, but it seems to always come back. Not a huge deal since the power button will always work, but it is disconcerting when it happens. I'm not using any power widget or lock program although I do use Nova Launcher Pro. Does this happen to anyone else and if so have you narrowed it down?

Mine always wakes my phone, although every now and then it doesn't recognize my print. However, I believe it's because of how my finger lays on the sensor so I think it's user error in my case.
I've registered 4 prints, 2 from each index finger and all in different positions on the sensor to get the least reading errors.
Are you saying that you get no vibration as in it doesn't even register at times therefore you HAVE to use the power button to wake it?
I use nova pro too.

Yes exactly, no vibration. I've had it where it vibrates and doesn't unlock because my fingers are slightly wet or something. This is like it doesn't even know my finger is on the sensor. Power button unlocks and then it works again. Last time I said ok I'm not unlocking with the power button I'm gonna get this to work. Nope, had to power button it on after a minute or so of trying. As I said, it's not that big a deal and only happens once in a while. Glad it's not Nova though. Kernel dev said it's not the kernel , I'm using Elemental X. I might try going back to the stock kernel just to test it out. Problem is that I can't reproduce it.

I get this occasionally when charging but that occurred on stock everything, can't say I've noticed it in any other capacity. Are you using smart lock or an app to lock your screen?
Edit: I should read your post before replying, disregard my app question. Still asking about smart lock though.

And I meant to include the "big" question in my original reply. Big being "what mods are you using"
Best way to trial and error issues as you well know? I'd test it on all stock (for a day or 2) and see what that gets you then you can narrow down to if it's the kernel or not. I'm not a kernel dev, but an educated guess would point to that imo

Smart lock, yes. Well smart unlock isn't it? I have a couple of BT unlock devices, Mi Band and car BT radio but that's it.

No mods.. well let me rephrase that. I have a bunch of programs running naturally, but the only "mod" I have is Cataclysm and systemless root along with Elemental X kernel. Cataclysm is considered a mod these days as it's just an overlay on stock 6.01. I know I'd have to go full stock to test for a few days but I'm so so trying to avoid that as I'm sure you know. Thanks for all the input guys, I know this can't just be me right? Hey wait a sec.. I do have a BT smart band unlock running. I'm going to take that off and see if that makes a difference. Maybe that is interfering with the fingerprint requirement.
Edit..nope not it. Gonna run stock kernel next.

The exact same thing is happening to me. Same symptoms but I am on fully stock. I'm also using nova pro. Been searching around for an answer but haven't found anything.

Too many people on Nova Pro for it to be an undocumented issue. I know it's been said that it is not the kernel, however, yesterday morning I flashed this one http://forum.xda-developers.com/nexus-5x/orig-development/jolla-kernelbullhead-t3271530 and I've not had the issue since. I usually have it at least once / day and none so far. That doesn't mean it's not going to happen in 5 minutes though. I went with stock kernel values if you're rooted and feel like giving it a try.

I was having this issue randomly when running custom hotplugging. Currently no issues with default cpu hotplug settings and ElementalX.

For me I have a case on my 5x. There are two cutouts - one for fingerprint sensor and one for camera. They're both about the same size. Every once in awhile I find myself reaching for the camera instead of the fingerprint sensor. When I first got the phone I thought my fingerprint wasn't working at times. Turns out I was just putting my finger on the camera instead of the fingerprint sensor. Any chance this is what's going on?

Don't make me question my own sanity! hehe. I did the same thing at the outset but quickly realized my error. This is not what happens here, however. I even put it back in my pocket once to make sure it wasn't some aberration. It just wouldn't recognize there was even a finger there. Almost thought the phone had shut down but power button got it working again. Haven't had the issue in well over a day now with this kernel but I'm not sure that's what it is.

Happened to me not charging, rooted with custom kernel. So it's across the board hit or miss. I have a feeling it will be fixed in an update or OTA. Not a deal breaker just odd is all. Oh well, if we didn't have a power button it would be major.

After 3 years of usage my Nexus 5X fingerprint scanner stopped working at all and i can't do anything about it apparently. The issues started when i sent the phone to LG to fix the bootloop

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.

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
