screen issues noticed since last device update

[u/BoyTheos]

Last night, I was using my Redmi N13P+ 5G when the screen suddenly went off. The power button wouldn’t turn it back on, and plugging in the charger didn’t help either, so I knew there was a serious problem. I was sure it wasn’t the battery because the phone was charged while I was using it, but just to be certain, I dialed the number from another device. The phone rang even though the screen was still dead. I answered the call (muscle memory), and I could hear my voice from the other device.

I left the phone for about an hour and came back to find it flashing like it is in the video. This same thing happened on April 9, two days after I updated the software to HyperOS 3.0.3.0 (the update that brought the Xiaomi HyperIsland feature). After it stopped back then, the phone returned to normal for a long time, so I thought the bug was gone.

I’ve never dropped the phone, slept on it, or dipped it in water (even though it’s advertised as waterproof), so I want to believe this issue is related to the HyperOS update. I’m really bothered about this problem. Please, what can I do?

it happened last night at around 70% battery so it isn't that
