This is my try to make a complete list of Jami connectivity issues on the Android Client as of the latest version on fdroid.
Jami needs a force stop every morning to get or send messages
Also There seems to be the image/file trasfer problems that are reported elsewhere.
Mainly here: savoirfairelinux/ring-daemon#66
and here: savoirfairelinux/ring-client-android#656
and here: savoirfairelinux/ring-project#696
this also applies on android: savoirfairelinux/ring-client-windows#582
It may sometimes get stuck in syncing data and it is not obvious to the user what to do. Or if it is even an issue.
Like here: savoirfairelinux/ring-client-android#683
Sometimes the connectivity will fail without an obvious error. This leads to the user not knowing if the app failed. That can happen at anytime during the day. It happens between 4-5 Times a day.
There is also the offline indicator. The green buble. Which right now may or may not mean anything since it never gets refreshed.
It is reported here: savoirfairelinux/ring-client-android#770
Also: savoirfairelinux/ring-client-ios#84 although its for ios it still applies here
