After the few recent updates of the app, it cannot provide notifications unless I open it, even though I disabled battery optimization. Therefore I always miss SMS messages from this app, which is extremely annoying. Reinstalling the app doesn't help either. Please fix this problem as soon as possible. Thanks!

The updated app just crashes if you deny permissions, which are excessive. Access to music & audio? Access to photos? Why would a phone call app need such permissions!

Poorly designed app, took 10+s to get to the main screen before you can tap on a number to do any operations. Please improve this app to make it open immediately without the lengthy loading process. Sometimes you just don't get the call after it crashed in the background. Message notification is delayed as well even i have turned off all the battery optimization for this app on my galaxy note 10. Suggested to add "Default number" so that i can jump into the main screen of the dialer app.
