I tried several times. It didn't work. I am the first owner of the phone. The screen is broken. The phone has no other physical problems. If I go to the service, I have to pay for the repair of the screen. I don't have a budget. I tried the Android 9 beta version. The problems continued there too. That's why I downgraded.
