Screen problem with MT8227L - Android Head-Units

Hello.
I have a problem with the screen, the whole top line of the screen is not working.
I tried updating version from android 8 to android 10, and then did format but without success.
In Google I saw that this is a known problem but without a solution, does anyone know how to fix it?
Thanks.

Thats crazy.
My original unit year ago was like this, edge swiping from the top was a roll of the dice if it worked.
Does it function with a touchscreen pointer?
When you play a full screen video, and touch the screen there, does it repsond?
If your touchscreen is defective and they wont replace it. try doing a wm overscan 0,40,0,0
more info here : https://forum.xda-developers.com/t/...gb-128gb-10-1-1920x1200.4365419/post-85990887
and by googling 'wm overscan android'

Bottom of Screen Does Not Calibrate

I recently purchased an MDA off ebay from another member on this site. They claimed everything on it was fine, but upon receiving it I found that the bottom of the screen didn't respond. After playing with the calibration I found that the bottom of the screen wasn't completely "dead" it just thinks its being tapped on a different spot of the screen. The seller claims this is a software issue, but after several flashes from different roms the problem still persists. Has anyone else seen this happen? And does this sound like a hardware issue?
I opened notes and took a picture of what happens when trying to use the scrollbar in landscape mode to show how off the calibration is at the bottom. Thanks in advance for any help I can get on this.

I had this EXACT same problem. I had the mistake of pushing down too hard while applying a screen protector and it pushed in the screen on the bottom. From that point, I could never calibrate the bottom of the screen. I was able to get a replacement, because I told Cingular that it was broken and it was only a month into my contract.
So, I think the guy probably messed up applying a screen protector or accidently somehow pushed in the bottom of the screen. This is in no way a software problem....deff hardware issue.
Thanks for the response. I filed a claim with paypal for a refund. With the way that it was packed I'm amazed the phone works at all!
Im sorry to hear someone trying to get over on you. Hope everything works out.

Is this a problem?

I just got this tablet recently, not too much surprise since i am already user android 2.2 rom on x10
But i notice there is time where this tablet fail to respond to touch command say after a long timeout. As in i can't move the bubble to unlock the screen at all
I tried to turn it off and the pop up wasn't even responsive at all to touch.
Is this a failure on my tab alone or anyone else have the same problem ?
Also it is common for the tablet to have a slow respond to screen switch and rotate a lot ? I found my tablet go portrait mode even lie down (i want it to be landscape).
please indicate what version you are running and what kernel.
i have no such problems running 3.1 upgraded tu .38
Wrongfeifong from The Order of the Silver Hand? If so Korgana here cool that you got this same tablet lol.
I've not had any problems like that yet.
No, I havn't had any issues and if you want to be landscape use the rotation lock switch, it's beside the volume butons.

Sorry, had to.... anyway, if you are running 3.0 and not 3.1 it could be the "Removal from Charger" issue and causes it to lock up? I dunno, like the others said, what is your current version?
I just got it right out of the box and never update
3.0.1 android version
2.6.36-0001 kernel
and hey small world isn't it? yea i am the same person from silver hand.

[Q] Using D2 off network

I have an extra d2 I want to use at home as an alarm clock (on a dock) and streaming device. I factory reset it and now I can't get around the new activation screen. Any idea as how to get around this? The touch four corners method doesn't work. The right edge of the screen doesn't respond.

Check out this link: http://theunlockr.com/2010/09/20/how-to-bypass-the-activation-screen-on-the-motorola-droid-2/
It definitely works, you just have to try it several times. Be careful not to touch the Change Language or Emergency Call buttons at the bottom.
Does not work on this phone
The phone screen does not respond to touch along the right side, (in portrait oreintation) I wound up activating the phone then changing back to my actual phone.
the four corners method, does work
This is the thread that helped me get past the activation screen. Thanks so much. Thought I was going to have to junk the phone because no one seems to have found an unlock code for the phone. Great to know that we don't need an unlock to get past activation.

[Q] Dropped phone, screen and touchscreen broken

Hi guys,
I accidentally dropped my phone on the floor.
This wasn't the first time I dropped but this time it's really broken.
The screen is broken and the touch screen isn't working anymore (looks like only 20% of the top part is working, rest of the screen not).

Is there any way how to control it from my pc now? It's rooted etc.
I'd like to make a backup for whatsapp and other apps.
Second thing, should I try to replace the screen and touch screen?
Thanks,
Niek

If the power and volume buttons still work you can use fastboot and adb.

Yeah I know I could use ADB.
But I thought that it's maybe possible to control it on your pc via an interface or something. So that you actually see your phone's screen on your pc screen.
There's an app called airdroid but i don't know how you can launch it without a touchscreen.

Important Information
Some devices/ROMs are having reboot issues, a nandroid/Ti backup is recommended before trying the app.
If your screen becomes unusable after setting a resolution, wait for ~15 seconds. It should revert to your default resolution.
If that does not work, reboot -> wait for 2 min (for the service to start) -n reset[/QUOTE]> reboot again -> wait for service to start.
If that too does not work (I certainly hope that you won't have to do this), issue the following commands in adb shell (using a pc):
For JB 4.3 and above
wm size reset
wm density reset
wm overscan reset
Click to expand...
Click to collapse
Also please note that uninstalling the app won't restore default display settings. So please switch the service off first, if you want to uninstall. Also tell me why you uninstalled it.
