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

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.

Apologies, first time I posted it I was thinking it was just Instagram-specific.

To me it looks like it is IG specific because I don't have this problem with any other app

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.

Done that but it doesn't solve this problem.

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.

Good to hear you got it 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

Camera gives error when trying to record video, mic only works for calls

When I try to take a video, it instantly says "Recording stopped due to error". When I try to use the mic for anything other than calling someone, it just doesn't work. I've tried restarting a few times, but that hasn't helped. I'm very confused about what to do here! Do you guys have any ideas?

Have you fixed this?
Have you found a permanent fix for this please? Thought I fixed mine after full factory reset but after two hours it started happening again. No videos work alwhatsoever, not even YouTube ...
Thanks mate

Video Stutter Issue in P2

from the last few days i am facing frame skipping in video playback (including youtube app, mx player, vlc) , the video lags and skips few frames.
I did a factory reset, installed deodexed version, wiped cache even reinstalled stock but the problem is still there
Anyone with some info please help
thanks in advance

Yeah bro,i am also facing same problem, BTW did u find any solution?

I'm also facing same issue after nougat update,
I have factory reseted my phone, updated all apps and applied system settings (enabled 'FORCE GPU RENDERING), but it doesn't solved my problem.

Yes it's present in stock ROM nougat version. On mm there weren't any such issues.
Sent from my Lenovo P2a42 using Tapatalk

i don't thinks that its a solution
but after flashing the nougat rom through fastboot the problem of stutter has reduced greatly
now it doesn't stutter that often

Any other solutions for this problem?? i have already factory reset it 2 times and i don't want to risk my new device doing fastboot flash :crying:

any solution for this prblm

I updated my phone to 244 and did a factory reset still the problem persisted but the stutter doesn't seem to occur when I keep it in airplane mode. Can anyone try this.

Guys, I guess I figured it out. Turning off the "participate in the Lenovo experience program" in about phone in settings fixed mine. Hope it works out the same for you guys.

Doesn't work for me, had it turned off from the beginning. The problem also applies to alarm sounds for me, they pause for a split of second every 10-15 secs, is it caused by the same thing?
Is this a common problem or only happens to some of the ppl? How can I know this? I bought this phone yesterday and after it consumed 25% of battery overnight I seriously consider returning it The battery was the main reason I purchased it and now is seems not only it doesnt work properly but other stuff is broken...

Did you update the phone to 244. If not then try it and check again. There weren't any other problems for me other than the video stutters.

If the question was for me, then yes, I did update to 244 and did a full wipe afterwards.

Hmm. Guess your only option is to give it to Lenovo service center and make them roll it back to marsh mellow.

Weird Bug!!! Seems it happens only when using Jio sim in nougat. It will not lag when u switch on aeroplane mod...

Same for me, airplane mode solves the stutter issue. Can you confirm that it works OK on other sim cards.

How does this help me with YouTube? I believe that it will not even load without internet? And what is "Jio"?

It's a 4g carrier in India. Btw have you tried airplane mode. We know that you can't use YouTube but try Mx player or vlc for stutters while in airplane mode. We just want to narrow the possibilities.

I bought a Bluetooth headphone yesterday and it seems to get worse. It was then I found out that an app named Android system was draining my battery but is not the actual Android system(check the screenshot).I went to the app manager and force stopped this app and haven't felt any stutters till now.
Edit: Although the app opens up after a while even if you force stop it and the stutters continue. Need to check after freezing it.

Does this problem still exist? Planned to buy this phone today... but meh, thats a dealbreaker.
Does this problem occur on Custom ROMs too? damn ... i want this battery monster.

The phone doesn't have any major problems such as this one on marshmallow at least from what I hear but running it on nougat will make you to face such problems and Lenovo provides a crappy support.

Screen Flicker Issue on Honor 7X BND-AL10 (Chinese Version)

I just bought the phone and I'm experiencing a screen flickering. At the time it occurs the screen becomes unresponsive. The bottom 3/4th part turns black. It keeps on flickering. The audio works when it occurs, but touch won't . It happens occasionally.
.
.
.
Maybe it occurs coz one day my phone dropped to the ground.
Any help would be appreciated.
[Update] : This happens only when using YouTube for a long time.

Thats the problem of YouTube not of the phone

Contacted huawei customer care regarding the same problem, they gave me an ota update which fixed the problem.

I used to get it but stopped having it. i didnt get any update. maybe it was youtubes issue after all

It's because of in-built YouTube application.. same happening to me as well. Finding a way to uninstall in-built YouTube app and download it again from playstore

It's not the phone's fault
YouTube isn't optimised for the phone yet so there might be some issues like the one you mentioned, but i haven't seen this problem yet at all.

Thank you everyone those who answered my question.
The problem was solved after clearing the data and updating the app.
