Hi, when I'm using my phone during charge the touch is very difficult to use. However, when it's disconnected it works perfect. I'm using LG's original charger. What could be the problem and how can I solve it?
Hello, I noticed again that while typing, I was missing almost every third word. It definitely wasn't a sensitivity issue. So I opened a browser and noticed that while scrolling up, it would pause or freeze every 3 seconds or so. I then closed all apps and it still did the same thing. It would even lag when trying to swipe to unlock the phone.
I unplugged the power cable as it was already fully charged and all the lag went away. Plugged it back in and it returned. This does not happen with the stock charger and it doesn't happen when the phone is charging.
Anyone else notice this strange behavior? I can't say that it always happens as but this is what I've observed today.
How do we report these issues to LG so they can take care of them in future updates?
quick chargers heat up the battery which in turn heats up the phone itself
phone then goes into damage control mode and throttles the cpu to lower the temperature causing lag
quick chargers aren't that good for batteries due to the heat generated..
I presume this is what is happening
He did say it was already fully charged, though. So the charge current & heat shouldn't really be higher than a normal charger, I'd think.
FWIW, my phone slowed down the charging numerous times due to heat (not a Quick Charger) and I never noticed any lag as a result.
does it slow down or does the touch/digitizer starts acting up?

It's not the touch response as the screen will pause then catch up to where it needs to be. Just letting my finger off of the screen doesn't do that.

I think i have an explanation to this:
When charging the digitizer is really affected by the current coming in. Since the digitizer is some kind of static electricity sensor, the "noise" coming from the current that's charging the phone will greatly affect it, especially a QC.

In Developer Options I found an option to display the touchscreen info as you use the screen.
You might try that just to help better understand the issue? Alternately, in Quickmemo+, try drawing on the screen to see what that shows. Does it capture the whole line if you trace around with your finger, etc.
I was drawing a huge mess in QuickNote and noticed that every few seconds the lag time is noticeable then it speeds up full speed ans fluid.
I think all of this is a weird processor throttling thing. I think because of the heat issues of the 810, the 808 was set to aggressive throttling and does a check every so often to look at resources and heat temps from battery, screen, etc that is causing misses, delays, and other irregularities.
Never did it break my line or make straight lines, but it seemed as though the FPS were dropping.
My opinion.

H811 variant here. No touch screen issues at all when plugged into an AUKEY QC2.0 charger or any other charger for that matter.

Oh don't get me wrong, i didn't test this issue just yet.
A QC is in shipment to me so I'll confirm this as soon as i get the item.

I completely agree with the comments others are making on this issue. I have seen this behavior on several phones and tablets. The strange thing I have noticed is that is seems to be the combination of charger, usb cable and device that seems to the cause. I can frequently change just the charger block or cable to resolve my issues while plugged in. Fast charge, slow charge, fully charged, or system load, none seem to be related like the cable.

I've done further testing. It runs flawlessly no matter how hot it gets but only gives this issues at 100% when the unplug message comes up. I still haven't tested if it does the same in my vehicle with it's qc2.0 charger but with my home charger, it does it with both high quality usb cables that I used. I played a video and it played with no skipping nor does the sound skip, just the touch input.
CPU usage increases while charging!! Dont know why
The exact same is happening with my phone as well. I installed CPU-Z app to debug the issue. The CPU usage shows instant and very noticeable jump when the charging cable is plugged in. This intense CPU usage is the prime cause of slow down. My keyboard becomes so laggy that it becomes almost useless, especially the Space bar. I tried to find which system apps are using the CPU resources while charging but unable to do it. I tried my luck by enabling "Show CPU usage" in developers option but as it seems all apps start to consume CPU as soon as the charging cable is plugged it. I now recharge my phone while powering off. My phone does not get hotter while doing so.

This happens every time on every ROM since on stock days buy I just realized recently that only when it's charging and it's getting worse to the point of unusable lately.
The responsiveness is very noticeable with dragging action, I tested it with touch screen test and when I drag my finger across the marker skips and shows imaginary second fingers, It doesn't happen when plugged and not charging. When unplug it is working fine as it should. Does anyone have this experience? fix? This is making me creazy. Thanks!
It's your charger. I'm willing to bet you're using a cheap one from china. The cheap ones put nasty voltage spikes into your phone that interferes with the touch screen digitizer.
Use the original charger or find a reputable one online.
I have noticed that when I charge the phone, the screen becomes unresponsive and I have to press multiple time to respond, both touch and slide commands.
Does anyone has this problem?
The moment I unplug the cable it works ok.
Only with fast charger. With usb cable in computer works fine.

Try to restart your device when fast charging or try another cable...
Tried with another cable and another charger with 2Amps instead of original charger with 3 amps and nothing.
This happends when the phone is discharged 3-6%. If the phone is 60-80% and I charge-it it works fine.
Bad earth connection of ur home makes u do that. Nothing alarming. Just dont touch ur phone when its charging u might kill something in it due to built up static.
I tried to play some games while charging and was imposible
Are you on CM13? Had this problem with every cm13 rom
It seems a cable problem or when you plugin you cable to the phone ,the temperature of phone will be higher , this will cause the touch screen more difficult to touch . maybe you can cold down the phone's temperature.
I'm on Cydras google edition. Works fine in rest. And sometime gets very hot. Like almost 50 degrees C hot.
I use L speed set on battery to calm down a little the cpu but nothing till now. It may be related the heat with screen not responding.
In the last couple days I started noticing the fast wireless charging is not turned on every time when I place the phone on all of my three fast charging pads. Instead the phone just shows the regular wireless charging status. If I lift the phone and put it down again, the fast charging will turn on randomly again with no observable pattern.
Does anyone have the same problem? I have wiped the cache,thinking it might have been one of the latest Sprint updates, but it didn't solve the problem.
I've had this issue too, how long before it's switching to slow charge? Mine does it if the temp gets too hot usually, but other times the wireless charge doesn't work at all. I think it might just be a bad pad though and not the phones fault...
Mine was doing about the same thing ...it would say wireless fast charge as soon as I set it on the pad and one second later it would say wireless charging. I switched the power brick from the one that came with the charging pad to the one that came with my s10 ( faulty brick maybe?)and that did the trick for me. For reference I'm using a Samsung wireless charging pad but that was my experience
