Hi, in august 2019 i bought a zenfone max pro m2, and, before upgrade it to android 9 pie, everything was ok but since I've got android 9 there are several problems.
The most annoying is when you turn on the phone and you must put the pin for starting the sistem and EVERYTIME appears this banner: The phone app still blocks. But from today when i turn on the phone, it doesn't ask me the pin for starting the sistem. And I've seen that the phone starts to be a little bit slower and I've noted little retards on the touchscreen when you press it and many times the phone disconnects himself from wifi.
So, what should i do? (I know the .12345+ trick on the calculator)
