New Update to New Problems: Touchscreen Random Presses

[Global]

Hello again. After this recent update, my phone sometimes randomly presses back button, or somewhere else randomly at random times. I have lost lots of my studies with this issue.

I did a factory reset and a clean install. Why Sony? This is really disappointed.

I had a an xperia p before z1 compact. Sony did not publish any working update and i suffered. Now i have xperia z1c. Again broken firmwares.
