I don't understand a word you're saying

After the update

• the portrait mode pictures don't really look like portrait mode
• the battery stats always show the last 12 hours, not since last charge
• The only bug I noticed in Flyme 6 with whatsapp calls is still present
  

I'm thinking about downgrading since I see no improvements whatsoever , there's no point in using a more bugged but updated version

I can also confirm that the flash (in flashlight and camera) does not use dual led. It only uses white color leds.
Moreover, I noticed that in portrait mode picture mode the images have the right amount of background blur but it is lost after the picture is saved.

I already did that. Sadly, nobody confirmed the bug. I guess it's lack of interest from the users
