[Q] Unresponsive screen on Atrix 4G

[comexx]

Hi,

After I switched to CM7 I started to experience unresponsive or crazy screen. By crazy I mean it's like touch screen calibration is somewhat screwed and it gets touches everywhere. When I turn off screen and on, it is gone. However it starts again after a while. I noticed that when I get my phone out of my pocket, it gets unresponsive. After I clean the surface and do on/off several times it fixes. Sometimes, it doesn't even get fixed so I have to restart the phone.

I also see that after a fresh ROM installation, issue does not appear frequently. After a while, it occurs quite often and my battery is drained as well. I doubt if that is an kernel issue or hardware. But since it drains the battery, it seems like a kernel issue. Have anyone faced a problem like this before?

Try the raindrop fix. If that doesn't work, you may need to replace your digitizer (or alternatively go back to stock ROM if the problem does not show up there).

Thanks ravilov, I didn't know about that. I downloaded and installed it. Problem doesn't seem to fade away but it usually gets frequent after few weeks. I will see what happens. As you said I'll try stock rom next and if that doesn't work either maybe it's time to change my phone.

Sorry to write to an old thread, but my problem is related.

So, after this craziness I wrote in my first post, my screen get totally unresponsive. I cannot use the phone. I decided to change the digitizer. However, the problem still exists even with brand new digitizer. I'm now wondering could it be due to front camera ribbon? I think that's where digitizer is attached to. Any ideas or suggestions on this?

Thanks!

I've just noticed another flex cable called earpiece ribbon. I'm confused, which one does the digitizer is connected to?
