I hear the notification sound for a new email (Gmail), but notification icon is not displayed on Always on Display, neither does the LED blink.
Spotify notification icon is still visible on Always on Display after media is stopped. It doesn't go away even after I swipe away the notification in the notification drawer. I have to manually close the Spotify app to get the notification to disappear from the Always on Display.
No notification icon on status bar when Spotify is playing media
Duplicate notifications from alarm app (Sleep for Android)
Alarm app doesn't automatically open when alarm is ringing; I have to manually open the app to stop the alarm (this might be a problem with the Sleep app itself, but this is the only phone where it manifests on)
These are the issues I noticed after only using the phone for a couple of days. Wouldn't be at all surprised if these notifications issues manifest with apps other than Gmail, Spotify and Sleep.
Smaller issues
The size of the clock widget is a lot larger than it's supposed to be (Can't upload screenshots for some reason)
The navigation buttons are too small. Wish I could make them larger.
Wish I could rearrange/regroup the apps in the drawer without going to Options -> Manage apps first.
Unnecessary and annoying vibrations that can't be turned off e.g. When scrolling a list and reaching the end, when opening notification drawer.
