[Q] Weird Touchscreen Issue - G3 Q&A, Help & Troubleshooting

I got my G3 about a week ago and have been thoroughly enjoying it, however in the last couple of days I've been having a recurring intermittent issue with the touchscreen.
Essentially what's been happening is when the phone's gotten a bit warm the touchscreen stops registering long presses or swipes properly, and adds random break points in the swipe, this is especially annoying when trying to use the continuous input on the keyboard or add widgets.
Obviously the phone's still under warranty, so I'll return it if need be, but I was wondering if anyone else was having this issues or had any theories.
Thanks for your time.

the lg g3 is on top 3 list this fall and I did read about some of the heating problems
but based on your comments and the fact it is under warranty, I would replace it at your earliest convenience--:good:

I have to admit I have had nearly the same issue. My phone has been perfect everywhere except when it gets hot from a highly demanding game (demanding in the CPU Heat generation sense, games as simple as Angry Birds Epic cause it to get hot) and once it does, it gets to a point the touchscreen become much more erratic and less consistent on detecting taps, swipes, and holds. This digs badly into games since everything has onscreen controls and when the touchscreen looses its ability to detect touches, then all bets are off until the device cools down a bit.
It is not overly hot or uncomfortable to hold. The phone feels rather warm but otherwise everything looks and runs fine, just the touch input goes to crap for a few seconds then comes back. Has anyone else experienced this under a heavy load?

Have you resolved your issue?

I've been having a similar issue with my LG G3. I'm very pleased with the phone's overall performance but it has this touchscreen issue that's really affecting how I can use it. It has a great proc and gaming capabilities but I can't play some games because I can't rely upon the screen to register presses every time.
Have you been able to solve your issue? If so, what did you do?

Touchscreen sensitivity and response when charging

I'm almost certain that I am not the only one who has had this problem, but I would really like to know if anyone is working on it.
When charging my HOX, I notice a considerable drop in all aspects of the touch screen. I am currently running IceColdJelly, and have noticed it significantly when typing out an SMS. I would hit one letter on the keyboard and the tactile feedback will go nuts and i would have ended up typing out a bunch of Q's with a large amount of spaces.
More to the point though. Has anyone looked into why this happens? and if there is a fix? It is really making me despise my HOX, which frustrates me because it is such a great phone when not charging.
It's not a good idea to use the phone whilst charging. I've heard of heating issues and someone electrocuted answering the phone. I stopped making calls on my xe earlier because of bursts of sharp pain on the ear whilst it was charging.
I’m not quite sure the reason for it, but I too have experienced it from time to time with different phones, and I have also seen few others complaining about it as well. Are you using the supplied HTC charger and USB cable ?
Does it happen with all chargers (different brands etc) and USB?
Edit: somehow I missed the post above. Where is the delete post button?
I've noticed this as well. I'm not sure if it's for the same reason but when I had my old Sensation it was pretty severe and the solution was to change the scheduler (?) to 'on demand', if you have an option that allows it. This fixed the problem completely. It was something to do with having 'interactive' selected.
However, I'm not sure whether the cause would be the same thing with a stock rom with stock kernel.

[Q] Touchscreen and sound problems.

Hello.
I'm using my nexus for a couple of months now (device is assembled in november 2013), and there are two issues that really bother.
First of all, response of touchscreen is not always correct: it sometimes misses some touches (press the letter on a keyboard, for example - and nothing happens until 3-4-5th touch) or handles single touch like multitouch (scrolling through the page in browser with one finger suddenly acts like two-finger gesture). It usually happens on the top half of the display and while tablet lies on flat surface, but not always: I have noticed same behavior in hands. There are no exact circumstances that show that bug always and for sure, but it appears once a day or two. Today, though, it didn't respond to touches at top half at all, and when I ran a multitouch test, I saw this: http://youtu.be/XwEDCwUZ8h8
The other thing is upper loudspeaker. While it is on, a weird high-frequency sound is present. I can not describe it exactly, but I have recorded an example: https://dl.dropboxusercontent.com/u/71375852/%D0%B7%D0%B2%D1%83%D0%BA1.mov In fact, it is louder: I can hear it from a distance of 10-15 centimetre, and it is even louder if device is charging. But verdict of service-centre said, that this is a software issue, manufacturer is awared and will fix in oncoming ROMs.
So the questions are:
1) How common are these problems? Are there any fixes yet? Are the any people who had a replacement or moneyback because of the issues?
2) Are there any official feedback from Asus or services that recognise these issues as hardware fault which requires a repair or replacement?
As I said, my service-centre did not confirmed the sound issue as hardware issue and they also did not notice the touchscreen bug. But the device still had a 20 days repair: the battery was replaced because of unstable work. According to our laws, I need 10 more days of repairs to get a replacement of the device or have the money back. But there should be exactly a repair of a fault which is covered by warranty: it won't work if after 10 days service will just return the device, saying it had worked properly. So any information about these issues would be really appreciated.
Thanks for any responce.

Anyone else having touchscreen issues?

Every once in a while I can't swipe down the notifications bar and the top 10% ish of the screen doesn't respond to touches.
Also, I seem to get quite a few false touches
I think i may have issue but not too sure will keep a eye out

I have an issue that is 100% reproducible on my G4.
1. I set in Dev option for the animations to be .5x
2. Swipe between home screens left, right left, then press any of the shortcuts in the persistent are of the screen (phone, camera etc).
3. Now try to do the same thing but press any app shortcut or even the recents button. it works fine. I think this is a software issue.
I freaking starting to hate LG UI.
No issues on my G4, however...
I had the same exact issues on the G2 where the digitizer and the screen had to be replaced time and time again, and it'd just break again. Seems like the heat makes it so touches don't register.
I posted the other day about an issue mainly in Pinball Arcade, where taps occasionally weren't registering a flipper activation. This problem seemed to extend into the OS itself, as I have had some hiccups while typing or navigating. I just wiped everything and am trying again...we'll see. But I want this figured out by early next week so I can take advantage of the 14-day period.
Seems to happen when the top part of the phone is really hot
I'm having issues with the touch screen just not registering taps randomly. i can be in chrome scrolling and just have it stop scrolling then decided to start up again and i have to press an app icon multiple times to get it to register. ive only had the phone for 5 hours now. very pissed.
going to go return it now. was going to get the nexus 6 and i should have in the first place.
Some taps not registering here too...sucks, but i don't see any other phone I like out there.
same here I'm having bad touch screen issue, will be returning just paid $635 for this
.. I just started having this issue after the recent tmo update.. Wtf
Don't seem to be having any touchscreen issues. Mine is only heat related. Getting new phone delivered today. Hopefully that will fix it.

It's normal to heat up the first few days while it downloads and installs all your data.
I've had my phone two weeks. It heats up to over 107F while listening to Tune-in Radio. Yesterday at the T-Mobile store it went from 81-107F after 5 minutes of talking on the phone and about 5 minutes of Tune-In Radio. The hottest I've noticed is 117F. This is under normal operation and NEVER happened with any other smart phone I've had (I've had smart phones since 2005). It will be in my pocket and I have to take it out because it's so hot. I don't play intensive games or do anything really intensive on it. The most intensive thing I do is watch youtube videos or periscope. I use this phone exactly as I used my G3 two weeks ago. Nothing has changed and no new apps.

Yeah, that's probably not normal if it's been two weeks. Mine was only warm the first two days, but it quickly resolved once everything's properly set up.
What's funny, is she went down a list of why my phone might be hot: did you leave it in the sun? are you playing intensive games? a case can cause the phone to get hot. using your screen at high brightness can cause the phone to overheat. LOL
I told her that when play store updates 2 apps, it gets hot. She said she could fix that and promptly went to my settings and turned off auto-update. REALLY?

Mines got pretty hot too when updating apps the first day of use, hottest I've ever felt a phone. I've been working at T-Mobile since 2009 and I always thought customers would exaggerate about a hot phone.
Different kind of touch issue
When i place my mobile on bed or any soft surface, the touch does not respond. Am unable to pull down the notification bar. Tried multi touch app and it does not recognize the touches itself. Someone help me out pls.

Mine is perfect except if it's plugged in and charging. It's much less responsive then, and needs a much firmer touch.

I just noticed this last night as well. I had it plugged in and it started to slow down a bit (Thermal throttling) and touches were less responsive.
At this moment it's working great. I really hope this isn't a heat/hardware thing

If you don't mind me asking, what are you using to monitor the temp?

A70 Touchscreen sometimes misses quick touches

Hi All!
I just got a new a70 5 days ago, it's performing very well, but i did notice one thing. Sometimes my quick touches when i just very quickly and barely touch the screen, the touch is not registered. I activated the factory diagnostic mode (*#0*#) and tested and got some interesting results. If i touch the screen quickly enough, the touch is not registered at all, even though i apply a substantial force. I can do this like 3-4 times out of 10 if i really try. I also tried it on my galaxy S5, and although I could reproduce the same issue, it was much harder to get it to miss a touch than on my brand new a70. I did try it with and without a screen protector and it didn't make any difference. I'm actually surprised, I didn't think I can touch the screen too quickly so that the sensor (or software?) fails to register it. My question is: is this an expected behaviour, or something that should be looked into? It doesn't really affect everyday use, but ever since i discovered this I'm now always having this weir feeling anytime i'm about to touch the screen that "is this touch going to miss?". So my questions are the following:
1. Is this behaviour normal?
2. Why does my S5 seems to be more "reliable" and is harder to get to miss a touch.
3. Is there a 'minimum touch duration' for these capacitive screens?
4. Anybody else who has A70 experienced this, could try it out?
(it was not very easy to reproduce at first. i started noticing it when i wanted to open messenger chats, that some of my touches missed. for the issue to be easily reproduced one would have to try and tap as quickly as possible, so that your finger touches the screen for the shortest time possible)

Yeah the touch on this device is horrible. Don't listen to fanboys, this device has a couple of issues other than the touch screen having an awful response time.
Check:
+
The SD675 isn't well optimized for most games, so it lags in most of them, while on the A50's weaker processor, the Exynos 9610, games work just fine. Most of the time, they work better on the A50 than on the A70.
And there's another issue with dark colors being turned off instead of dimmed, because the screen doesn't know the difference between "dark" and "totally black". I'm gonna demonstrate this later by comparing the A70 and A50 side by side.
The A70 has a stronger CPU than the A50. The A50 has a stronger GPU than the A70. The A70 has better battery life.
That said, yeah touch problems. I notice it all the time when browsing. Trying to tap on small links are not registered most of the time. I have to zoom in.
I believe it to be a hardware issue that is not fixable in software.

Weird Digitizer Issue (Just me)?

Fellow Pixel-ers,
So, I broke my screen about 8 months ago. It had coverage and got it replaced by a Google authorized screen fixer place.
I noticed early on that things didn't seem quite right. If I pushed down too hard on the screen, my touch wouldn't register. But, it didn't happen too often and I didn't want to have to deal with arguing that they may have poorly installed the new screen/digitizer and that it wasn't 'my fault'.
As time went on I started noticing that the almost bottom of my screen would not register a touch but mostly only at night. Again, it didn't happen too often and it usually went away after a little poking/prodding/pushing/.
I also thought it might be an application that I gave 'screen Overlay' rights that I shouldn't have and it was causing issues.
I validated my issue by using a Touchscreen Test app.
When I use an app like Vysor I am able to 'access' that area of the screen even when my fingers cannot. Does that validate this is a hardware issue?
The area affected was definitely more than just a few pixels (see screenshots).
More recently it was happening more frequently (not just at night) and it almost never goes away.
I wanted to make sure it wasn't a software issue. So I planned on dirty flashing my OS (AquariOS), but actually ended up accidentally upgrading to a clean version of Android 10. Unfortunately, the issue was still there.
I then did a clean flash and downgraded back to Pie w/AquariOS.
Shortly after getting back up the issue showed up again.
At this point, I have virtually lost all touch response for the bottom 1/8 (not quite the very bottom) of my screen. I've had to use a floating keyboard because the space bar falls right in that area. Sometimes I can't click 'next' or 'continue' in apps or web sites.
Has anyone ever experienced this very odd digitizer issue like this? Any thoughts/suggestions/ideas.
I'm guessing the only solution is a new phone as it is not worth the money to fix it.
So now I'm just waiting for either the Pixel 4A or 5 to come out so I can get a new phone I guess.
I just find this very odd how specific this area of 'dead pixels' is. I always thought it was more random than a specific rectangle.
I look forward to hearing from anyone.

Hi bro, I've face the exact same issue, but for me it was at the center of the screen. Luckily my phone was under warranty, but getting them to replace my touch digitizer was a whole different thing. At first they just didn't acknowledge the issue, then I tried showing them proofs but they didn't believe as they were from some third party apps. Finally, I used markup to show them the issue and recorded it took some screenshots as well. So, they replaced my digitizer at last after constantly speaking them for 2-3 weeks. I can only suggest you that if your phone is still under warranty or you have accidental damage coverage, ask them to replace them. Otherwise, it'll be better to buy a new phone as replacing the screen from your pocket may be very costly.
For anyone who reads this thread,
I resigned myself to having a bad digitizer but was starting to look to replace the phone. Then about a week later I inadvertently dropped the phone in a pool. Unfortunately, as the screen had been replaced the waterproofing was no longer good and phone was a brick. So I never resolved the issue but will always assume that the company that replaced the screen did a less perfect job and that when a screen is replace the phone looses it's waterproofing ability
