Hi,

My phone is:
Xiaomi Redmi Note 4
Android 7.0 NRD90M
Doit version 4.4.9

I can't set the sound of notification, it constantly "crashes" and goes back to settings.

Here's the video of the bug. :)

if You need logs or any more details, don't hesitate to contact me.

Or is there a different way of reporting bugs I should take?
