Huawei Ascend Mate 2 touch screen not working after being replaced - Huawei Ascend Mate 2

I have a Huawei ascend mate 2 consumer cellular branded MT2-L03. I have replaced the screen and digitizer twice now. The first time around the display was fine but the screen was unresponsive. Went back check my connections and figured I got non working piece in the kit. ( I ordered a kit with screen, digitizer, and frame together) Returned it and got a second one. Same problem. Does anyone know if another component could be messed up on the board? Could this be a software problem? I noticed a touch screen firmware update option in the reset menu. I'm still new at this. Thanks.

Also have this issue - I've replaced dozens of screens on different devices over 10+years and have had no issues like this.
Seems a little strange that there is a spot for "touchscreen fw" in the recovery yet I have yet to find any info on this after quite a bit of searching.
Feel free to send me a "let me google that for you" if I missed something.

[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.

Touchscreen Unresponsiveness?

So I made the jump from Android (Nexus One) to the Radar and I really like it so far!
I do, however, have an issue with the phone that I am wondering if anyone else has noticed.
I have noticed that sometimes when I go to touch a tile(or other UI object)...if I quickly touch it, it seems that the screen doesn't always detect my touch. Sometimes I'll even hit it a couple of times before it responds.
The behavior is inconsistent though. After it smartens up and responds to my touch, then it seems to detect it fine. It's squirrelly and a little disconcerting.
I also think that the region of the screen might have something to do with it. The tile 2nd from the top on the home screen ("messaging" in my case) seems particularly susceptible to this problem.
Has anyone else noticed this? I'm a little paranoid because I bought this phone "new" from someone on CL and when I took it home I realized it was a refurbished model.
I had this problem when I had my 7 Pro. After a while it got worse, as I had to put the phone on standby and then turn it on again to be able to use the screen. I sent it in to HTC for repair, and they swapped the entire front panel with a new one.
Im having the same problem with my sprint arrive I think the problem is related to what is in this thread:

but I still cant seem to get it to work

Scary moment for me and my One X+

Hello everyone, I'd just like to share something that happened with my HOX+.
Earlier today my touchscreen acted up and was getting random touch input on a particular portion of the screen. Thinking it may have just been something on the screen like oil or whatever, I just gave it a quick wipe and it went back to normal.
Now a while ago, that particular portion of the touch screen totally died on me. I didn't think it was a software problem because I didn't flash anything or install any app from the play store. Also, that portion(about a half inch strip from the top of the phone when held in portrait edge to edge, left to right) wasn't working even in recovery(CWM).
So I searched the net for similar accounts and found put that it may be a faulty digitizer. While I do have official HTC warranty, claims in our country(Philippines) usually take forever if you get past all the retailer and distributor bullcrap at all.
Luckily, I happened upon a single post somewhere where this person just pressed hard on the unresponsive portion of his touchscreen(different device) for a few seconds and the problem went away. Fortunately it also worked for me.
Just sharing my experience just in case this also happens to someone else. For now I'm hoping the problem does not reoccur. I've also secured my Proof of Purchase to be sure.

EDIT: Based on the fact that I could now pull down the notification bar, I assumed the whole screen was now OK. But now it seems there is still a narrow strip which is unresponsive. I'm now starting to think this was caused by the pouch I had been using which had a clasp corresponding to that location in combination with the long time it had been placed in a tight pants pocket earlier today.

dead bar on part of screen

Hi all,
so i have an issue with my p9000. There is a "dead" zone on my screen, it's about 1.5cm wide and covers the screen from left to right.
This part of the screen stopped working a few days ago, it's not responding to touch. Rest of the phone is fine, everything works as it should.
Can this be because of some wrong settings in screen size in rom or any other settings, or is the screen most likely dead ?
Seems like there is a faulty batch
I got that problem too.
Mine is on Eragon ROM and part of the screen is unresponsive in applications other than the Nova Luancer.
My device has the same issue. Try to zap repeatedly the dead part of the screen with a piezoelectric tool, such as a mosquito bite relief device or a lighter. Works form me, but it's only a temporary solution. The issue comes out again from time to time.
So it looks like a device issue then. Was hoping for software error.
i have the same problem. It is not software error unfortunately. Looks like a faulty batch to me too.
I use Eragon and was dealing with the same issue. Then suddenly it disappeared. After flashing an update it came back and then it disappeared again. Since then everything is fine
Ok, now this problem is permanent. I talked with Banggood and will send it back to the service.
So I've sent one email to elephone support department. They were offering me a 15$ discount. Was very surprised. Anyhow during further conversation they have agreed to fix the device. I will send it as soon as I get another device I can use daily.

Problem with touch screen or software bug?

I bought a Mate 20 Pro on preorder and noticed within a few days a seemingly non-responsive part of the screen that was an intermittent issue.
Basically every now and again (often enough it’s annoying but not every time) after I unlock the display I am unable to select any app icons in the lower half of the touchscreen. The top half is fine - the home buttons are fine but everywhere from the middle down is non responsive.
I assumed a hardware fault so amazon replaced it for me - and the new device is exactly the same!
Am I just super unlucky and have managed to get two faulty devices a month apart from Amazon or is something else causing the issue?
Thanks.
Think you've just been unlucky,nothing like that on mine
Fine here too. I assume you tested this as soon as you got the phone before installing any app / custom launcher?
Have you tried running smart diagnostic tests manual mode in hicare, there's a touchscreen display test.

I only noticed it in use after I used a custom launcher however I tried multiple launchers and saw the same behaviour.
I just did the HiCare test and it says normal. I did hard reset it the other day and it hasn’t happened since so I will see if anything else happens. I can’t say I am thrilled by the thought of another swap from amazon if it does happen. That’s super bad luck.
Hi how did it go after the hard reset?
I got the same issue myself but instead of being the lower half, my entire screen does not respond to touch. I've done a hard reset my self and i do run the stock launcher. Even though my screen still doesn't respond to touch now and then after unlocking the screen or receiving a phone call.
Touchscreen issue
Yup I get it annoyingly so as well! Often takes a "double tap". Pain in the ace!
