I'd love to go back to an older version of the android or use another ROM that VADUS is talking about, but unfortunately it is not as easy as updating using the local method. I am a layman in these matters and if the recording of OREO was simple, then returning to the old software is a big risk for me that I will get stuck somewhere, especially since my English is very weak.
OREO does not work as it should, thanks to your advertisement I updated the smartphone to 8.0, it was supposed to be beautiful and sucks.
The problem exists not from yesterday or even from the month, but for much longer. Something to do with it and not just write "you can always go back to the older version". I will do it as it will be as easy as updating the local method.
