Atrix lcd issue. - Atrix 4G Q&A, Help & Troubleshooting

hi there
I've got some strange issue with my lcd screen on my atrix. Everything is on this video(sorry for quality):
http://www.youtube.com/watch?v=bbMsmbblXLc
I don't know what to do- i don't have my warranty because of unlocked bootloader(in Poland they are very strict and surely they won't fix this on warranty.
So the issue is: when i touch near front camera/ front speaker the virtual finger appears. The second thing is that when i touch in showed area
there are 2 touches from one finger. It isn't a rom issue because it is on all roms i've tested.
If you have any idea what should i do please write it
Thanks in advance for any help

I'd say your digitizer is dying. Except unlike most others where a part of the digitizer stops registering touches, yours registers multiple touches. Either way, I believe buying and installing a new digitizer would fix this problem.

After a night which phone spent in home there is no additional touch in this line. Of course the issue with touching near camera didin't disappear.
Maybe it is because of very low temperatures in Poland nowadays and i think there can be some water inside of phone. But as you said
i'll think about changing digitizer

[Q] Rare Touchscreen Issue: Faulty Horizontal Line

Hey guys,
My screen woes just won't go away. I dropped my phone a few weeks back and cracked the screen. Ordered a new one from eBay (Item number: 260818538062) with the faceplate and everything. Had it installed but then started noticing that SWYPE wasn't working as well because my words would start breaking midway. Installed Yet Another Multi Touch Test and when trying to paint realized that there is a very evident line on my screen that isn't working as well. That was one continuous movement of slow up and down jestures but as you can see, the touch sensitivity is much weaker as well as the screen sensing a second touch at some point.
What can I do? I will gladly take the thing apart and clean the connectors.. if that will help. But somehow am inclined to believe that the issue lies with the screen. Is there a software recalibration fix that exists perhaps? Anyone experienced the same thing and walked away with a working solution?
Please help and thank you in advance.
(EDIT) I've added a second attachment where I started going around the outer edges working my way in, there's definitely one faulty line in my screen!
(EDIT2) Found a native Android touchscreen test (white and green) thanks to a member named BryanNL in a different post. Basically had to dial *#0*# and chose it from a menu. This test claimed that I passed but you can see that it is not made to tackle an issue like mine.
Bumping.. Anyone please.

[Explanation] Ghost touch

{ Disclaimer: the following text is my view about this problem. I'm not in any way responsible for any damage }
As there is very little info known about this phenomena I will try to explain it. I learned a lot of disassembly guides and by visualizing it (settings-development-show touches)
Ghost touch is a strange phenomena of various types and is due to a hardware fault between the mainboard connector and digitizer screen, I'm therefore trying to clarify it by categorizing them in three groups:
1. Small; Screen is unresponsive. 1 lock/unlock and it works again. Almost perfect. No need to replace screen. Most common.
2. Large; Same as 1, and often up to 5 touches and the touches are often moving/pressing parts of the screen. This can become a very frustrating period. Messaging apps and settings can be messed up by these touches. Often a lock/unlock will fix this temporary. A full screen replacement is recommended
3. Unworkable; Same as 2, and the lower and upper part are not working anymore. Notfications bar can not be pulled down anymore, typing become a nuisance and it not possible anymore and you curse your phone. Also it is not even possible to insert your pin, unlock your phone etcetera. This problem will not be fixed by a restart/reset or lock/unlock. A full screen replacement is essential.
Many people say this can be fixed by software settings, however this is a hardware fault. I tried many different roms and I encountered at all of them. The only fix that can be done to fix this is replacing of the full screen as it is not possible to apply/remove your digitizer.
For a long time I thought it was due to the degrading digitizer or something, in fact it is probably the connection between the and the mainboard. The screen has two digitizers: One for the touchscreen and one for the home/settings/back/search buttons. For some reason this last one did not cause any trouble. The first one has a flex cable from the upper part of the screen leading toward a small hole and heading to the mainboard. The problem will probably reside in the part between the digitizer and the small hole. Here, just above the screen, the flex cable is folded 180 degrees. This fold will cause the problem as it is very sensitive. Mine has a very small damaged part, the copper parts are visible. The cause of this is due to the rubbing of the bezel just under the speaker.
How to fix it?
Buy a new screen including digitizer (often HTC & Sprint branded) and make sure you protect this part as much as you can.
EDIT:
I re-inserted my old LCD display with a bit of tape around the damaged part. Since then I haven't had any ghost touches.
Mine was ghost touching so bad it was completely unusable for a few days. I was thiiiiiiis close to buying a new phone, then one day it just stopped and hasn't done it again since. Very strange. Anyhow, I will be replacing it with an s4 when the price comes down to $100 for us SERO users.
Ghost touch
Nice explanation, and nice 3 lvl sorting but, tell me one thing... I have experience with lvl 1 and 2 (two different phones) and for both of them simple ROM change / reinstall helped to solve this problem.
For ex. I had JB [ROOTBOX] ROM since the last week.. ghost touch problems were getting worse and worse with each new day yet lock/unlock still worked quite well.
I decided to test new JB MIUI ROM and like a magic touch my ghost friend is gone since than, but I am afraid he will return more powerfull than ever... oops that is a different story. However my phone is now working fine ... no ghosts detected.
So please don't tell me that this problem is only mechanical problem ( due to ROM change / reinstall worked multiple times). Actually I am pretty sure that is software problem which is supported by hardware hitches.
My friends "ghost story" is pretty similar.. but he reinstalled back original ICS ROM.
PS: I don't want to start flame war with this reply. It is just mix of my experience and opinions.

Line on keyboard off calibration after screen replacement.

I just got done replacing my broken screen on my LG G3. I replaced the whole front panel and just transfered the guts. Everything checked out fine after replacement until i typed my first text message. row A-L will not goto screen unless I touch nearly inbetween the middle of the row beneath it. q-p work fine as well as z-m. What really has me boggled is that the screen accepts touches there in virtually every other app/drawing. Just the keyboards aren't allowing touch in that specfic row. any suggestion?
Found a few more bad section.. Pulled the back loudspeaker back out and tried reseating the cables and still had same issue. They're sending a replacement for free.
This was my first screen replacement, but not my first time dealing with small ribbon cables. All cameras function fine, hoping it was a defect in screen and not my screen changing abilities.. Any tips for the next one would be appreciated. Would like to have a fully functioning phone again sometime. This is nearly more frustrating than the broken screen.
I am having same Issue

Hey just curious if your issue has been resolved.... I am having same issue, but i took mine to a computer store i have been dealing with for years. about a year ago they started doing cell phone repairs as well. I had them replace my cracked screen on my LG G3 and that same row of text if off for me and there are a few other spots i have noticed are off as well .... very frustrating... Anyway the place I took it to has replaced 3 screens hoping they were getting defective parts.... they just called to tell me I can come get it but they were unable to repair the dead spots without going further into replacing boards or something.... I dont know... It is weird though cause you can get the dead spots to work sometimes by very lightly touching or just touching it in just the right spots like a calibration if off....

A review on G3 LCD's on Amazon reports the same problem "I installed the screen and immediately my wife mentioned that it seemed to have "dead spots" when she was texting / playing games. I noticed it myself when I tried texting myself as a test. Several of the letters on the keyboard just wouldn't register very well. She went into the settings and ran the "motion sensor calibration" test under general settings>gestures. This has resolved the touch screen issues. "
I don't see how that would fix it but I guess it's worth a shot.

Moto e dead spots on touch screen

Hey guys, a friend of mine give me his moto e cause he had soft bricked it. Reading through the forum I could reinstall the firmware (4.4.4 latam) and now it's working fine, but there are 5 spot in a vertical line that doesn't register my touches, these spots are aligned in the middle of the screen, one is at the y position of the keyboard, and the others are separated 1cm each other (1 is under the y and the other 3 are above). Could this be a software related problem or I just have to replace the touchscreen? (I've tried factory reset two times but I've not reflashed the firm again) thanks in advance and sorry about my English.
First take a try with Screen tester app die playstore, and change rom once, if didn't helped, you can replace screen assembly at low cost on local markets.
Well, i've reflashed the stock 4.4.4 firmware and it's still the same, i guess i'll have to replace the touchscreen. I dont know how the touchscreen works in this phone but it's a little strange that certain isolated areas in the middle of the screen doesnt work..

I had the exact same problem. I had 4 such huge spots on the left side of the screen where touch didn't work. ROM reflashes don't help. Yeah it's really strange. First I thought it might be cuz of water spilled over the screen but later on found out that the display assembly is completely sealed and water can't get in. Yeah it's really strange how display suddenly stopped working that way..even touches of local phones don't get magically spoiled like this, dunno what's up with moto. I got it replaced from local market for 1300. I would say the quality of the display, touch, brightness, contrast, everything is same as that of the original display. The only thing I suspect is that the glass is not gorilla I guess.

Screen is locked but responding to touch

I have a very irritating problem my device touch screen is responding even though it is black and locked. It keeps annoying me when i am in a call and it is only a matter of time till it ends the call. Problem started after having a screen replacement but i can hardly believe it is a screen problem because it is functioning normally and also gets dark when i am in a call. My proximity sensor is working as it should. It is like my screen gets dark and not totally off.
My phone is rooted and i am running lollipop 5.1.1 custom rom

It sounds like you are having ghost touch problem. This usually presents itself when you change the front glass with digitizer and leave the old LCD. This cannot be repaired if this is the case. I dont think this is a sw problem. When did this issue started to manifest itself? Right after the screen replacement or it started to appeare gradually?
Yes it appeared just after repairing the cracked screen. The lcd was working but not the touch and the glass was all cracked.
How can i solve this?

One thing to mention is that i do not get touches that i didn't make. They are just getting read when the screen shouldn't read them.

But does touch work normally when you use the phone? Ghost touch can manifest itself on various ways, like your case or can go completely crazy when the screen is on. You can try some apps that resolve ghost touch like touch fixer. Some people are saying that unlocking BL and flashing CM resolves this issue and other sollutions you can try is to apply heat with heat gun or hair drier directly on the screen to make sure the glue is sticking the digitizer onto the LCD propperly, or fiddle with the flat cable contacts bit by bit until the touch is working properly but this requires disassembling the device again. You can alway try to flash different firmware to see if it'll resolve your issue but I highly doubt it will. GL
