I created a custom logo.img for Mi Mix 2 (chiron) with instructions to create your own one.
chiron logo.zip
This is not a bootanimation, is the logo shown when phone power up.
Tested on Mi Mix 2 (chiron) with xiaomi.eu rom. Dont try on another devices.
I created a theme file (.mtz) with boot animation only. It can be open with any archiver tool like WinRAR and replace the bootanimation.zip file inside with your favorite one.

with Mi Cloud enabled works, so a better description of the bug is "Gallery unable to delete images located in sdcard/pictures/screenshots/ when Mi Cloud is disabled"
On MIUI 10 "Nature sounds" is the default notificación sound, but if you choose another sound how to get back to "Nature sounds"? is missing on sound list.
Is possible to trigger PiP mode or Google Assistant using Full screen display setting (no navigation bar)? I accidentally did PiP mode grabbing phone on edges but I m unable to replicate it.
