Possible Fix For Touchscreen Issues/Misses (Updated 08/29)

[xchasa]

Phone on table.
10 fingers down in paint test mode

 

[joshuadjohnson22]

Just downloaded YAMTT app and all 10 fingers register on a table with V10f.
Will try getting a screenshot with 9 or 8.
Definitely not hardware in my case and touch used to suck.

Exactly what I wanted to see, thanks! We have hope

-1 or -10?

-10 was an example of another value to try. People report differing values for the "sweet spot", and negative values are used. A value between -1 and -100 seem to be common.

I am physically not capable of registering 9 touches and taking a screenshot, but I can assure you guys that it works while laying flat on a wood table (v10f).

it's ok it normally spazes out at 6 anyways. 10F FTW

trying it at -100, will report back, but seems ok so far

Nope not fixed 100% ,,its better but when it on a flat surface it's going crazy and can't pinch zoom ,,and multi touch not working,,, just working with one finger,,i have v10c,,so what do you think??

I've the same problem, I think also is a ground issue. If the device is in my hand it works well, but if I left it on a table or in the car holder is impossible to use it, YAMTT doesn't detect any touch.
When it is in the car holder to use it I've to touch the back cover with a finger to use it.
My release is V10C

After seeing so many people with 10C still having the issue I want to think that 10f can't possibly be the same as 10c. So far no one with 10f has had the issue and said it completely resolved the issue. There must have been something different. We need to get a rom of 10F going to confirm.

seems to be working a good deal better with debug.egl.swapinterval at -100, but I still get some swipes interpreted as taps

I just tried Phone Tester a fairly new hardware testing app, and unplugged it would hit 6 fingers on screen and just stop saying 6 touches, then plugged in I was able to get all 10 several times. VS986 on 11a Verizon here.

Please could all of you, including anyone else who has done the build.prop change that I haven't quoted, perform the same test as in this video here: http://1drv.ms/1MOwkQD

I tried the test with stock build.prop, default settings. The app (YAMTT) would stop recognizing all taps after 6 on battery, but registered 10 with no problem on charger.

well considering that everyone is saying the latest updates fix this issue I would have to say it was a software issue. Multiple people confirmed the fix to be 100%

What is this "latest update" you're referring to?

 

[joshuadjohnson22]

What is this "latest update" you're referring to?

10f, it's not available to everyone yet. Just 815 Au. So far they all confirm the issue is resolved.

Well....thess U.S. carriers better hurry the **** up and push the update out to us as well. It's the one thing keeping me from loving this phone currently.

Couldn't agree more :-/

Someone will probably make a rooted system image we could flash with flashfire before that happens!

A couple things would have to line up perfectly for this to happen... and it still would be questionable:
1. Partitions would have to be exact
2. It would have to be compatible with the kernel (hopefully the fix is not in the kernel cuz unless the hardware is identical we will have to use ours)

I'm not dev so this is just what I understand, if these things aren't right it may result it bootloop, force closes or security errors. Hopefully @diedemus can get a return to stock set up, if that works we may have a shot. He may even be willing to try it out since he seems to know what he is doing.

Great, glad that more updates work. Can you register more than 6 touches at a time without the freak out?

 

[Mr.Miyagi555]

These missed taps is probably the most digusting thing about this phone. I dont understand how QA could have missed this problem.

Another thing i seen in a thread and verified myself was the max processor speed my phone uses is 1.4 ghz on bbs. Can someone else confirm this too?

After i random freak bootloop i dont want to put xposed or tweak the build prop yet. It doesnt seem likely that we are going to see some update from lg for this screen issue? I know its most likely hardware but couldnt they tweak the software to soften the blow?
