Damn! Just give a try wiping system partition because I'm also using k20 pro eu stable 10.4.4. If you're handy with it then you must give a try it will workok im back after installed stable version (i was on 9.9.6)
First Camera doesnt work! it ask for micro SD to take picture or whatever else.
second i can install only a few apps from playstore(i cant instal fb viber etc)
I did clean isntall (wiped everything exept system,reboot to recovery transfer the rom and install) then after these issues tried to clear wipe.cache i did factory reset again but nothing still have the same bugs.
now im flashing again dev rom..
device k20 pro.
