On the forum miui eu i en I found 3-4 people with a flashing screen in Mi8. There are a handful of us. I'm probably the only one on the Miuipol forum. I am looking for more people with this bug. Since updating 8.11.1, I have been flashing the screen. This happens in the evening and in the morning. Sometimes you can not even run the screen in the morning. If you have this problem, answer a few questions:

1. Do you have a Chinese or global version of Mi8?
2. When did you buy Mi8?
3. When did you notice the problem? From which update?
4. When does the problem occur?
5. What have you done so far to try and fix it?

My answers:
1. Chinese, Mi8 standard 128gb
2. June 2018
3. Update 8.11.1
4. In the evening, in the morning, especially after prolonged unused phone while turning off the device, while waking up the screen with a button or fingerprint.
5. Wipe all, Factory all (TWRP), clean installation of 8.11.1 and 8.11.8, Miflash chinadev 8.11.8 with cleaning the phone to zero. Installation fix from the brightness of the screen.

Nothing will help. Possibly for a moment.

I take into account the hardware defect. But I am surprised that several people suddenly came to almost the same time.

What does the screen flash when you turn it off? I recorded when switching off the device, but similarly it looks like when you wake up the screen with a fingerprint or button:

I can not speak English very well. I would like to help solve this problem if it's the fault of the software. Can mi8 differ in components / drivers?

I thought to add an error log, but I do not know how to register it. No error message is displayed.

Same problem...
1. Chinese with global, Mi8 standard 128gb
2. August 2018
3. From lastest update in December. Couldn't remember which was.
4. In the mornings and evenings, after long unused phone, and while waking up the screen with a button or fingerprint. And now it does this everytime and it doesn't turn on at all.
5. Everything possible. Didn't help. :/
 
If it's happening after clean flash it sure does look like a hardware issue.

I've only experienced something similar after installing a broken "darkmode" MIUI Theme but forcing reboot and uninstalling theme fixed it.
Think I've read something on MIUI forum of this also sometimes happening with some devices when amoled brightness is set to low ?
Those people use https://play.google.com/store/apps/details?id=com.appwriter.amoled_saver&hl=en_US Amoled saver app to increase min. brightness as a workaround
