Hello, I have a question about my phone xiaomi redmi 9c nfc which I bought at the mobile emergency e-shop today I came I dragged most of the data into it and installed some games and applications all day pedaled like a watch but at about a quarter to nine when I played the game it began to grain like an old television and a whistle so I pressed the buttons: mute the sound and the switch. The mobile phone went silent and went out, then I tried to turn it on, nothing responds when connected to the charger Please advise me Thank you Petr Dvořák
