20 and 30 are having some bugs after update I mean at least during the update the phone heats quite a lot but a little bit but not too much either but the problem is if you have a face Unlock set up it becomes slow so that's why I have to reset the face unlock I mean do the face unlock setting again then the other problem is it is like little slow but it is almost the same didn't improve battery life so please don't install this update if you understand me thank you very much like and comment if you have anything to say thank you
