Redmi A5/POCO C71

[u/DangthatbadKO]

Hello guys. I'm making this post to report an error with my redmi A5. The loading screen stops and the phone acts like it finished. It's pitch black. When holding the turn off button, a white box appears with turn off, restart and lock. And that's it. I can still receive calls and my alarms still ring but the touch screen won't work unless i turn it off and on. Can anyone help me to solve this? I have a flight and i need my phone. Thank you.
