Ghost typing/over sensitive screen

[Mi7]

Hello,

I have this Sony Z ultra and recently I've been noticing that the screen just goes crazy and random things are pressed without me doing anything.. Apps open and close, letters are typed while I'm messaging or sending SMS.
I've researched issue online and most contribute this bug to the kitkat 4.4 update and several people are encountering this same problem, just a bit of most or oil on the screen it goes nuts.

If anyone solved this issue please help me out.

Thanks! Very much appreciated

I believe this was solved in a firmware update and was caused by Google Chrome so you could open Settings then Apps and swipe to all the locate and open Chrome and tap on Uninstall updates then reboot and test making sure not to allow the app to update itself once rebooted untill you have tested it

I've had the exact same problem.Even with a little moist in my hands the screen went crazy..I simply added a cheap plastic screen protector and problem solved.
