[Q] LG P920 3d Touch Screen strange behaviour

VERY strange touch screen behaviour
Device: LG P920 Australian Optus Model, was upgraded to 2.3.5 using LG tools, then rooted ( cant remember which guide I used but it installed a package and su, was not superone click, maybe VRoot? it was for 2.3.5 and it worked) .
- then updated to v28b- eur- xx ICS , 4.0.4, kernal 3.0.21 using guides from Drastic00 xda guide
I am a bit of a phone noob, just learning to root using old samsungs and did my first ics flash on the LG P920. All good so far and thanks to all the guide contributors.
So the problem I am having in that the touch screen has two dead sections, the bottom section exactly covering the area occupied by the phone , message ect icons, and half way up a similar size section right across the phone. I have searched every post and forum I can find and cant find any thing like this. The touch screen works, just not in those sections. To get around it I can some times flip the phone to access things on parts of the screen that work, but a lot of time not.
I believe this started after I rooted the phone, although its always had issues with touch lag. If I hadnt rooted the phone, and its was just some random section I would put it down to hardware, but using the developer touch screen tests i can see the dead parts are exactly rectangle over the main phone controls at the bottom, which seems to me to indicate software, and on the new ics home screen I have activated the touches to be visual, and there are quite often two touch points racing back and forth along the little white line just above the dialer, message ect icons. when this happen you cant activate anything else because it thinks you are using two touches on the screen already.
I have used the LG remote computer controls program and i can access all sections of the screen perfectly through it, so that rules out everything but the link between the screen and phone in terms of software/ hardware. Have pulled off the ribbon plug and reattached also. I was hoping after upgrade to ICS it would be resolved but no luck. Unfortunately I cant remember how I rooted it but it was working fine for a few days then i noticed the touch issue after I started killing bloatware with Titanium. Is it possible removing an app has somehow messed up the touch screen code and its somehow not being repaired by the ics upgrade? Anyone seen this type of thing before. Found one post with a dead section after removing an app, but wast the whole bottom section and no ghost touches running around. Possessed?

actually this post is similar to my problem but no solution found, will contact poster to see if it was a screen failure or software. My screen is also periodically doing the flashing buttons, going beserk thing as described in this post.

[Completed] [Q] Method of dimming nav bar?

Hello,
First of all I have no idea if this is on the right section, so please move it if it isn't
I usually watch a lot of videos on YouTube in bed, leading me to desire a very low brightness. On my SGS4 running CM11 I simply used lux lite and twilight and disabled the capacitive button backlight. I since got an LG G3 and I'm facing issues. I would like to dim the nav bar to a brightness to that proportionate or less than the actual screen, as the nav bar is burning my retinas out!
I've tried nearly every app possible and still nothing works. This is quite a key thing for me and is making me seriously consider the much more expensive note 4.
I'm quite desperate now, and will try root or non-root solutions. My G3 isn't rooted but I will try root solutions on my S4.
Thanks in advance,
Chris

[Q] OnePlus One Screen Problem 44S

Hi,
Is there already a thread for OnePlus One screen responsiveness issues running on 44S? I've had a look but haven't found any.
I'm experiencing screen issues:
Two separate taps are sometimes registered as a swipe
Sometimes a single tap is not detected (hard to reproduce, though)
I have made two videos in preparation for a warranty claim, but I want to see if there's anything I can do before having to send it in for a month. The first video is of me typing - not using swipe/glide gestures, only tapping normally. On several occasions it thinks I'm swiping, however.
Sorry! I really want to post links to my videos, but I'm a new user.
OnePlus have admitted that there is a problem, but I heard they completely fixed it with the 44S update. Could it be that there's still something wrong, or maybe I have defective hardware?

Sir,
Please wait until mods will move this thread to the device specific forum.
Stand by
Good luck

[Completed] Nexus 5 BLACK SCREEN ( FASTBOOT ONLY)

I had my nexus 5 using multirom manager i had liquid smooth and paranoid android roms on it and i flashed ubuntu too the phone was working fine on all of the three roms.. the only issue i had was the microphone that wasn't working on phone calls but it worked only on speakers so i tried to change the mic piece and same the mic wasn't working. So i thought that it was something wrong with the software and i tried to flash a different kernel (Franko Kernel ) and i tried to flash couple GAPPS and nothing still with the mic problem and in the ROM i had a message that says com.play.services not responding so i tried to go on play store and upgrade the services and the play store wasn't working so i dowloaded some play services from chrome, after i installed the apt file i tried to reboot the phone and as soon as i did the reboot the screen had some rainbow an gray colored lines all over the screen horizontal and vertical lines, after that the screen was only black but i could see the backlight on it. I tried to restore stock with fast boot and still nothing i restored android 4.4.4,5.0,5.0.1 and nothing happen the screen was still black, the only thing was that the phone was able to be seen on fast boot and so i thought that the problem was the screen or the flex cable so i tried to buy a new screen i did ordered it from eBay and last night i changed the screen, but nothing worked I'm still having the black screen and the phone is still going on fast boot mode but I'm not able to use my phone... PLEASE HELPPP !!!!

[Completed] [Help] How to edit to fix some bug ?

Hello everyone,
I turn to you after a pack of unsuccessful searches for problems I encounter. And not enough control to correct the problem despite several attempts. Here is the challenge :
Indeed I have an Archos 53 Platinum under CM10.1 that; left a few seconds without activity (viewing a web page, read an E-book, ...) refuses to answer the touch screen or the touch keys. However, the notification bar can be deployed and navigation from there with the touch screen is normal (except touch keys that still refuse to answer).
Lock / unlock the device returns to normal operation of the appliance until it is stimulated. But this will cause premature wear of the On / Off button already fragile phone.
I have tried to change the options and lock timeouts and screen, nothing there. Resettlement from non-zero more. And the concern does not seem material as it works perfectly ignition and unlocking, as well as not passing the notification bar.
I wonder if anyone has an idea to bring correction?
