The phone froze so I decided to restart it. Unfortunately it didn’t turn on. The battery was 80% charged. I gave up trying to turn it on. After a month, I connected it to the charger and the screen showed that the battery was charging. After some time, I managed to turn on the smartphone and everything was fine until I turned it off. Still the same problem. The last time I turned it on, I downloaded the update and, of course, after restarting it, there was silence. Now I have to wait again until the battery is fully discharged.
