Screen problem with Z1

[Crush65]

Hi!

I have a screen problem with Z1

After a couple of minutes of use, phone becomes rather hot. Then various problems with screen occures (for instance, in some apps which use graphics on screen, like Sketch, especially in puzzle Nonogram https://play.google.com/store/apps/details?id=com.ucdevs.jcross ), in random occurence  :

- tapping some point at screen causes mark 1-2cm away

- tapping some point causes screen movement like after swipe

- tapping some point doesn't cause anything

- pressing and holding some point causes screen to shake (like performing very fast swipes in several directions)

Have you ever heard about this type of malfunction?

Thanks for your response!

Which version of software you have? Which operator?

It may be software related (you may try to repair firmware altough it will wipe phone memory so copy them first). If it doesn't help you should contact Xperia Care and service center.
