My Redmi note 9 keeps going on and off, when there's a call immediately the phone rings it goes off and restart. When I'm watching movies on it if there's a change in the sound of the movie, maybe somebody is shouting it goes off and reboot.

I thought it was a virus and I factory reset my phone but there's was no improvement. I also updated the Redmi note 9 to the latest update still the same problem.

Please how do I solve this issue?

I think you've been hacked
Just dont use it anymore coz your personal details might be stolen

Talking from experince

Sell am here. Xiaomi enthusiasts will buy it

I use note 9 too and nothing of such from mine

From what you said, i think it's hardware not software, probably the battery.

You guys don't listen. This phone no follow
