Ever since I’ve done the latest Mi software update, my Xiaomi 11 Lite 5g has acted pretty strange. Sometimes, when its screen is turned off, it briefly vibrates at random.

Now, since last week, I’ve had instances of its screen turning black at random with no chance of turning it back on again. Pressing the power button for 10 seconds does nothing, charging it does nothing, it’s not shown as a device on my computer when I connect my phone with it. The battery is fine as well. Sometimes, again, it vibrates at random.

The first instance of this happened last week on Tuesday. I did all of the things I just listed and at some point, after letting it sit for a while, it restarted seemingly at random and worked again. Second time happened yesterday. None of those solutions worked and I had to bring it to a phone technician who switched the screen receptors. It worked again perfectly fine.

But now, it happened once again despite the fixes. The screen is black, I can’t do anything anymore, I can’t turn it off or on.

Please, does anyone have any clues what I could do to fix this? I’m really stumped at this point.
