[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.

Question, do you have Google keyboard installed? Because I just removed Google keyboard and installed SwiftKey and it looks like the problem is gone....

Nope, I use Swiftkey from the beginning. Only LG stock keyboard is installed.

Mm, I've got LG keyboard freezed with TB and after changing from Google keyboard to SK, the problem is gone

Interesting. Not keen on rooting though. =\
So you reckon it's just a software issue?

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?

Help! Ambient mode seems to freeze watch.

Have had the Huawei Watch for a few days and it seems to have a deal-breaking bug. Frequently, after the watch has been in ambient mode for a while, it won't come out of it. If I touch the screen, the ambient display gets brighter, but that's all. No response from swiping or button presses. Sometimes, after a very long pause (a minute or so) it'll come back to life, but usually I have to hold the button until it restarts. Anyone run into this before? Ideas? Any help is greatly appreciated.
Using it with a Nexus 6. Android wear version 1.3.0.2176821.
Thanks!!!

Forgot to mention that the time sticks at whatever time it freezes and so it doesn't even tell the correct time. Sigh.
Have tried a factory reset. Didn't fix it.

Sounds like it's maybe in need of replacing. Like any new product release, there's bound to be a certain percentage of failures. Depending on how you look at it, you're either really lucky, or really unlucky

Well, just in case anyone else encounters this issue, I called Huawei tech support and described my issue. After a few minutes, they came back and said it was a known issue that effects some but not all watches. They said it would be corrected in a future software update but he was unable to tell me when that would be. So I could either wait for that update or send it back for an exchange. Since it happens frequently and renders the watch temporarily unusable, I opted to exchange it. They send an RMA label next day. The joys of new tech. Hope this helps someone else.

I have absolutely same issue. In ambient mode it freezes from the first day I bought this watch. Thank you for investigation and info.

got my hwatch and experienced the ambient mode freeze. to unfreeze, i enter and exit theater mode. it works. but now i'm never sure if the ambient time i'm glancing at is accurate or not...

Similar problem with an HTC M8. I'll try the theater mode to see if that helps. I still can't trust the time any more.

+1 on the Huawei Watch freeze. Sometimes after 15 minutes, sometimes after several hours. It has frozen with ambient mode disabled and with wrist gestures disabled as well.

Two watches and no freezes here. Are you guys testing with no Wear apps installed and with a built-in Huawei face?

Yes, after factory reset with no additional apps and with original buil-in Huawei faces and used to freeze. I returned it to the shop, got new one and problem is fixed.

how are you sure that the problem is fixed as opposed to it not showing yet? the freeze seems to be random and i don't know of a way to replicate it on demand. thanks

thanks, good to know. i'm curious if your replacement watch has the red-tint issue. i wonder if the two are somehow related.

None of them had red-tint issue. It seems this is not related with the freezing ambient mode.

Thanks, that solve my problem as well.

Happening to me too. Was using 3rd party skymaster watch face.

Got a replacement from amazon and it hasn't froze yet in the past two days of using it. The last one froze several times a day

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

It's not a screen issue, it's a software issue.

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.

An issue with calls dropping on S20 Ultra - Proximity sensor issue?

So I have a very weird issue and I'll try to explain the best I can;
For some reason, ever since the S10+ I've had issues with Samsung phones, I think its something to do with the proximity sensor that's now under the glass, I'll explain as I'm getting similar and more issues on my S20 Ultra.
So last year when I had an S10+ and when I was on a call, which I mainly use my left ear (I think my right ear is a few db less so I use my left) I would quite frequently seem to activate the menu (top right) and therefore end up pressing things with my ear, unbeknown to me, sometimes I'd add a 2nd person to the call or simply put the other person on hold! This happened a lot and I was close to sending it off for repair even though I used apps to test to ensure the proximity sensor was working correctly but in the end, I sold it and got an OnePlus 7 Pro, which I didn't have an issue with. During my time with the S10+ I noticed that even though I held the earpiece to my ear I could see the screen light up and that's where I think I'd end up pressing the screen accidentally as I've just explained.
Roll on to now where I'm facing similar issues but also I'm finding if I need both of my hands and therefore use my left shoulder to keep my phone against my ear the call disconnects as if I'm hanging up. Now it seems a straightforward resolution which is not to do that but I've never had this issue before and I've tested it out quite a bit when I do this the screen isn't on and my face is nowhere near the end button!! It's really driving me crazy at the moment and annoying my other half who's normally on the phone to me when this happens!!
Anyone got any suggestions or thoughts, does it happen to anyone else or am I just being stupid??
I haven't gone down the route of resetting the phone yet but I'm going to consider it.
