It's working for now.
Just what I wanted!!!
Old version (before the update) was of more use. No more timer. Now cannot select the ringer tone. No silence for given time amount. Overly complicated with lost functionality from prior version. Lost two stars due to update.
New version took good thing and made it bad. Lost simple timer functionality and crammed advertising in the middle of the configuration screen. Too bad.
The only app you need to set up automatic volume and vibration rules. I just wish we could choose the old notification icon.
After MiUi9 update app is not working.once you closed app automatically the app is closing from notification tab on top.
Show back to normal dialog in app too
Show systems: 'raise volume above recommended level' dialog when unable to set the volume. (should fix a bug where user unable to set volume more then 46%)
Fixed some bugs.
Increase volume of the phone speaker, music player & listen to music louder 🔊
Volume booster for headphones, phone. Play music equalizer in sound booster app
