Hi,
using last weekly, the flashlight refuse to turn on using notifications shortcuts (the icon stay disabled), same from lockscreen + left menu
it's not broken since it the camera flash is functional
i didnt find any report about this problem, so is there an easy way to fix this ?

thanks in advance

I had this problem with 8.12.20. A reboot fixed the problem. I don't have it in 8.12.27.

Before the reboot, try to turn on the flash from the camera app, video mode in the upper left corner - torch and see if it's working.

Regards!

As I said I made a clean install :
New phone, unlock, latest fastboot, twrp, wipe system,data,internal storage,caches(=everything available in twrp wipe selection), xiaomi.eu 8.12.27, magisk

I start to think that ironically the reason it work for some people is that it remains something from previous versions which may be missing in last 8.12.27 ;)

If I remember well, in previous MIUI (7or8) on redmi4x, there was a flashlight app in 'tools' folder, maybe a hint about what is missing ... or this app was removed in his stand-alone form in latest MIUI versions ?

I think the problem is elsewhere. There was officially no China Dev 8.12.27 published. Also, no Global Dev 8.12:.27 for the MI8. I suspect that a closed beta was used. On the official Xiaomi Site in China it was reported that there are Problems with the Version 8.12.27. In the MI8Pro (equuleus) the flashlight works, with a double-click on the power button as it should be.

Hello, I had the problem also.

I moved the icon to annother place. Everything is working fine.

Reboot -> everything is fine. Moved the icon to the old place -> everything is fine :)

yes for me it's solved since i upgraded from 8.12.27 to 9.1.3
but i'm convinced it must be a combination of actions affecting settings related to this app
- cache&dalvik clearing from twrp
- notification shortcut moving
- miui updating
