I will post this also here to (hopefully) get help faster.

So after updating to Uitukka phone just freezes frequently especially after if one wants to launch app. Screen goes completely dark for 5sek and then works again. But again if one tries to open app screen goes dark. This happens ~5 times after phone goes completely dark and doesn't respond to anything.

I would not like to do factory reset, atleast yet. Any help?
