So, hi guys. LTL; FTP; and so on. This has had me baffled for the past 7 hours of the day. The "patient" is a HUAWEI MediaPad 10 Link+ Model No. S10-231L. I replaced the touchscreen on it after being cracked. The touchscreen model and the model of the device match. The replacement went without a hitch, the new screen fits fine, until the time came to test the new fit. And what do we have - nothing. No touch input is ever recieved.
So far I've tried all I could find on google on debugging this with the adb shell, and have come to a conclusion, after doing hotswaps with the old display, that the new one is not recognized at all. No input device is created, etc. Both screens share a Synaptics s7300 controller, with the spare having an additional 3531 on the IC. Tried several reboots, looked trough all the logs, and got nowhere... Any ideas or knowledge, anyone?

Hello
2 days ago I got a T-mobile MDA from a friend. Only the MDA and a cradle. It had not been used for at least half a year. At first I could not make it work as it did not react to the stylus on the touch screen. But after some resets it slowly came on, and was fairly working (slow sometimes)
As I wanted English SW, I downloaded one and installed. After some time the problem came again, and I decided to switch back. Then it stopped working again.
Sometimes I can get to the calibrating touch screen, but then it stop reacting.
I read about similar problems on this website, but I cannot install the file tpenable.exe until I get into operating system, and can use the touch pad.
I tried with a couple of ROM-versions, but it seems to have no influence. Still, to me it feels like a SW-problem.
Anyone have some suggestions?

Follow up
Here is a follow up on my problem:
I discovered that if I press hard at the lower quater of the touch screen, sometimes it works again. This points more to a HW problem.
I took the MDA apart a couple of times, but could not see anything wrong. Does anybody know how the touch screen technically works?
I noticed in another post about someone with a similar problem. Do anybody know what exactly he was soldering?

Hi folks
Just inherited a very worn out one year old Xperia X10 from my son. Been trying to resurrect it.
About 2 or 3 months ago the touchscreen started to become non-responsive occasionally. Admittedly, I didn't look at it for him at the time. Then he dropped it down the loo (think - hope! - there was only water in it at the time). We dried it out in the hotpress and it worked ok but still with intermittent touchscreen not working.
He got a Blackberry from Santa, so a couple of weeks ago I inherited the Xperia. The screen was cracked in several places and totally non-responsive. Rather than chuck it in the bin, I thought I'd try and fix it up. So I bought a new screen on ebay and the other night I dismantled it and fitted the new screen. Touchscreen is still totally non-responsive. There was a slight rust on the perforated metal plate at the back of the screen which I carefully cleaned with WD40. All the connections and circuits look ok. I've updated it successfully on both PC Companion and SEUS.. I've also tried flashing using instructions from this forum but cannot get it right (most flashtool symbols greyed out). I have a feeling that it's a simple problem but just can't get there. The screen display is fine, I can get the camera and the keyboard up using the buttons. But damned if I can get the touchscreen to work. I feel the problem harks back to when the screen was intermittent - it still worked after the water/screenbreak, but not that well.
Anybody got any ideas or should I bin it? (Can't seem to get any worthwhile advice on the WWW - happened upon this forum while searching and thought - "This is my MAN". (One suggestion I saw on the web was to try a new battery - can't see how this would make a difference, present battery working fine. Also, I wondered if the proximity sensor could be on all the time?)
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.
Sent from my HUAWEI LYA-L09 using XDA Labs
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!
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.
I've had this tablet for a long time, unlocked but on the latest Huawei rom (Android 9).
Unfortunately, my daughter broke the screen. I've had it replaced with a part from China and at first, it worked fine but after a while, it started locking up for a couple of seconds once in a while because of touch. The screen broke a second time and had it replaced again, with another part from China from a second manufacturer. This time the problem with touch is even worse. It even does not work in recovery.
So, does anyone have a nonworking M5 8.4 with a Good screen that I could buy to try to fix my SHT-AL09? There is simply no other tablet with good specs and cellular connection with this size.
Thanks!
