LG G3 Top touchsreen issue - Android Q&A, Help & Troubleshooting

Hi all,
New here, just want to find an application (or an Xposed module) that "down" by some pixels the touch trigger for my notifications panel, as the top of my touchscreen is unresponsive (a top row of about 2 pixels ,the screen is perfect) and i can't pull down the notification bar, it seems to be a problem with the digitizer (this is strange as the problem appears just after my update to 6.0..) i read many forums and this seems to be a commun issue with many users, note that the notification panel is accessible when phone is in portrait mode, will be

(URGENT) Disabling a "real-time test mode"

Hi all,
I have a Hero H5500 (also known as ZOPO ZP100 but with a different ROM inside), it's a MT6575 phone.
Last night I fell asleep while watching a Youtube video (yes, that happens sometimes ^^) with the phone in my hand...
But when I woke up this morning, a bad surprise was waiting me :
I guess I involuntarily made a shortcut which activated this kind of "real-time test mode" on my phone :
[D*** it !!! I can't post the screenshot because of spam preventing It must be THE thing you need the most to solve my problem !!!]
the blue lines are what I do with the touch screen (which reveals another big problem I have, when my phone is plugged in, I have a lot of touch screen glitches : my finger did just do the "U" in the middle).
some infos (like the position I touch for example) are displayed in this line on the top and there is a real time display of applications and services used by the phone with some indicators of CPU used like a task manager...
Is it an Android native feature or a MT65XX firmware feature ?
How to disable it ?
Thank you by advance !

touchscreen problem - dead row

Hi,
my Atrix is behaving strange lately, but i just don't want to let go my old lady... so anyone has any idea re. root-cause of the problem?
situation
i got aware that the touchscreen had stopped working for a particular row, next to the volume control buttons. for me, it's been clear: hardware failure.
i wanted to see the symptoms in detail, hence installed a diagnostic app to check the touchscreen and identify the "dead zone" properly.
SCREENSHOT #1
but
when playing around, in the endeavor to paint all my screen blue, swiftly swiping my finger across the touchscreen. after a while, the phone's reactions became sluggish, and the home/back buttons would not bring me back to my home screen. so i switched the dialogs off and on again (power button). and the home/back buttons returned to work fine.
BUT
to my utmost surprise, the touchscreen problem had gone!! no more dead areas in the touchscreen!
SCREENSHOT #2
only after a while, the problem returns and the very same row is dead again regarding touch inputs.
Amazing! and this is fully reproducible! it's necessary for the app to react sluggishly (which is only randomly achieved), and the home/back buttons to stop working, to temporarily 'heal' the touchscreen.
So it's not a hardware, but software problem?
what's your opinion?
BTW, I am running a rooted stock release, european version, atrix 4g.
cheers
chris
There are no screenshots in your post.
Also, there are plenty enough threads about this, was yet another one really necessary?
Problem Cause - Solution Approaches
OK, sorry. What's the solution: 1 - 2 - 3 below?
1) Sounds reasonable - bad contact in a connector:
Emerging Hardware Issue: Touch Screen Dead Zones
2) This does not help a lot. Seems only for custom ROMs:
touchscreen is off only at the bottom of the screen
3) That's not very helpful - there's no description what the idea behind this mod is.

4) Do what most of us have done, which is replace digitizer or replace device completely

its working fine here on 850f running lollipop. ive tried many times real slow n fast. But i cant say anything about screen not working during games cuz i have no games on my phone.
I am facing the same problem from 1month.
I have replaced Screen (previously Display was broken and i had replaced)
Previous one had same problem ( Top left ) , before i went to Service centre , i droped my phone and its display was broken , i have replaced display around 4months ago , and now from 1month i am facing the same problem again ,
When i Swipe notification panel from very Left side , at 40% times , it doesn't drop down , it goes upwards ,
I have faced in Six guns game , Moving button isnot working properly sometimes , than i have to lock the screen , and unllock the phone again , after that touch starts working normally , again It stops again i lock the screen and so on.........
So is this common problem with most of the Alpha's screen ?
Same issue here... bought 2 months ago with Lollipop 5.0.2 already installed. Very annoying with games!!
By the contrary, I also noticed extremely high sensitivity over the screen: I don't even need to touch the screen to press buttons, simply approach finger by half centimeter it is enough. I don't know if it's something expected, but I didn't noticed this with my former Galaxy S.

Its a very strange thing , touch fixed it self and its working fine again since 15 days , i think its software problem
it happened with me too , i'm running 4.4.4 stock , i wasn't able to tap on the wifi button on the top left , enabled the "show touches and show pointer location " on developer options and found that the top left corner is not working , strangely i restarted the device and its all working again so i think its a software problem , also i'm suspecting its related to using a screen protector , didnt try further tho

It seems it's not software related, issues are confirmed both with Kitkat and Lollipop.
It's strange because on my alpha i haven't notice any issue about the touch screen.
Please, can you do this simple test to analyse the overall screen sensitivity?
On 'Settings' go to 'General' tab.
Then roll down to 'Developer Options'.
Activate "Show touches" and "Show pointer location" - it will show the touch interactions on screen (it looks like scratches but don't worry they are just drawings).
Then slide your finger over the screen surface and notice if the track is marked in all areas. Especially in the upper left corner. If you notice a fault on the track in this spot it means the screen has a 'dead' sensitivity area.

I found there is a more simple way to run several test on our device (and also available in other Samsung models): type on the telephone keypad *#0*#
As I reported previously, my screen was touch insensitive on the upper left side. Everyone can check this running the 'Touch' test.
My screen module was replaced under warranty and it seems fine now.

Cubot Note S - Vertical white lines on the Screen (software error)

Hi, I bought new "Cubot Note S", what I discovered in the first use was "display whitish" lines lying vertically, when set to high brightness.
At first, I thought it was hardware problem, but later I observed, actually those white(ish) lines are present when:
- screen brightness is higher than about 70%
- and when display is showing darker colors (mainly for notification bar)
- or when using camera.
And also, when moving notification bar up and down, those "whitish" lines moves sideways!
I found one solution for this problem, with the help of "MiraVision" user mode settings, by altering "Color temperature, brightness, and contrast".
You can see the problem and solution in the VIDEO.

Questions:
1) Is it really software error, or hardware problem?
2) If it is a software problem, is there any stable custom rom for "Cubot Note S" ?
Thanks!

Send the phone back to where you got it for a refund.
Many traits with the cubot note s include -
Doesn't boot up and hangs.
Boots up and the sim icon is missing.
Screen burn.
Boots up and sdcard missing.
Problems connecting to wifi.
The ota updater is dangerous and should never be used.
It has a couple of malware apps in system.
Volume button not working as it should.
There are also lots of pro's of course so it is worth £50, but only £50, no more than this.

Watch Touch problem

I am using an Asus Zenwatch 2. I had a problem with the touch screen and the left side of the touch is disabled for sometime now. But since most of the middle and right side is working and I had no issues using the watch.
Today the watch got updated to the latest Wear OS and once the watch restarted, it shown a message that the Wear OS is updated and Learn More about it. From there, it shows swipe in different directions, but since by left side touch is paralyzed, it can't complete the Tutorial. Now, my watch has 'Swipe in another direction' message is always displayed.
Is there any way to kill the tutorial ?
