Hey guys,
I was using my phone, everything ok but SUDDENLY it seems to have some touch issues! Sometimes the touch is unresponsive, for like 0,2 / 0,3 sec. I press and I have to press it again. That's frustrating!! Especially when typing on keyboard!! I thinked that the problem was caused by the ROM ( maybe little lags ) and I changed ROM, but the problem is still alive!! The phone didn't fall, this happened suddenly!!
Can someone help me?

Clear cache/ dalvik cache/ factory reset and see if this helps.

Also, did you dirty flash your ROM ? This usually happens if you dirty flash a ROM. Always start fresh.

Secondly, if you made backup and trying to restore it, that might cause the problem.

I tried to wipe.. but same issue. I always did the wipes before flashing a new ROM, so I think the installs were always clean. I tried to flash a firmware with flashtool, but same result..
Is there a solution for this? Now I'm trying to flash Gingerbread firmware, but I think the problem will remain..

Well, 0.2 seconds is a very small delay. However, if the problem persists, I suppose you should check typing speed/sensitivity in settings.

I suspect you have alot of applications in your phone and Xperia U has only 512 RAM which is not enough to run JB smoothly.

Nope.. I know that our device can not run lot of apps, in fact I have just some apps, no Facebook and something like that..
Anyway, for example, I did a touch screen test : it works in all zones, but, if I touch the screen 10 times, only 7 times can be "received" from device

Maybe the digitiser is having some sort of problem. This is usually caused by humidity / water in your phone in small amount . I hope I'm wrong.

Clean your screen thoroughly and remove screen protector and use ultra thin protector instead. See if that helps. On my devices smudgy screen has problems with touch .

Maybe it's caused by charging the phone with non-official chargers. It overcharge all the hardware and can easily damage it.
Anyways if you have warranty you can flash the original ROM, relock the bootloader and bring it to Sony.
