Intermitten touch screen - 8125, K-JAM, P4300, MDA Vario ROM Development

Hi all,
I'm having a problem with the mda wizard touch screen when I'll have to bend or press hard on the side of the screen so that I can get responses from the touch screen. Is this some kind of cold solder or loose connection or it simply a defect? Thanks!

i have same problem.

[Q] Screen not responsive after Armorsuit

Hey Guys,
For screen protection, I applied armorsuit day before yesterday on my tablet.
Picked it up yesterday, although I see some spots on the screen but the big problem is the response time on every touch
I have to press very hard whenever I touch the screen, if the tablet is on the mattress even after pressing it hard it ignores the touch
Then I have to pick it up and press hard.
I don't know if this is something to do with armorsuit installation or TF300 touch is like that.
Any help\suggestions will be appreciated.
Note: If I don't see the response time improving unwillingly I will have to remove the armorsuit protection,(Waste of 18 bucks)

[Completed] Screen is black and touch screen is unresponsive

Hello, I dropped my phone a while ago (a couple months) and it cracked the screen allot but the touch screen and lcd/digitizer were working with no issue.
Recently i dropped it again but this time on soft carpet and the LCD and touch screen are not working anymore, the LCD isn't cracked at all. The LED light at the top works and the back and menu buttons work fine.
Help?? plz
There's nothing anyone out here can do to help you for physical damage. You need to either have it repaired or purchase a new device.
Thank you

Touch screen going crazy

Hi guys,
I have a Dasaita PX5 unit with Android 8.0 and 4 GB RAM.
I've bought it a few months ago and it was working fine until today the screen just went crazy.
The screen will start touching itself all over and enabling settings, or quitting my GPS software, or activating apps, or flipping through different screens etc.
I've tried to update the system software, update the MCU, and even a factory reset. The crazy screen issue still persist.
Any idea how and why my screen went crazy and how do I resolve it?
Thanks
Here is a short sample of what I meant by going crazy:

I know exactly why and have had the same problem. There is a ribbon cable that comes out of the screen between the glass and LCD for the digitizer, its damaged the screens are so cheaply made the glass is still somewhat sharp and the cable kinks and breaks. . I actually just came on here to post if anyone knew where I could get a replacement besides Aliexpress.....
You should try reconnecting the ribbon cable, else just get yourself a screen replacement from where you bought the headunit.
I had similar issue where bottom part of the touch screen no longer register touches and as time goes by, the whole screen is completely "untouchable".
The root cause is that the ribbon between the unit and the screen panel connect to the mainboard is rubbing against the unit casing's sharp edges causes permanent damage. Fortunately, it is still under warranty and i have got a replacement panel, smoothed the casing edges and place some duct tape before replacing the panel.

Screen Lost Touch when Laying Flat

My phone is having some sensitivity issue. When laying flat on surface or sometimes holding my phone with one hand, the screen will have intermittent touch.
E.g. unable to scroll the page instead it will click to the screen. Is there a way to increase the touch distributor sensitivity like Samsung phone? Or it is a hardware issue? Thanks
