Greetings everyone. I have a S21 and my phone randomly restarts or gets stuck at boot. And also when my battery is 5% it drop down to 1% in 2, 3 minutes but i dont use my phone on charging and i use the orignal charger and cable. Can anyone tell me what is the issue or anyone else facing the same issue?. Regards maarij
