Is there a way to debug a firebase database connection (Android)? I'm using a really simple example (nothing big, just two listeners that listen on changes) that checks the value of /.info/connected. Most of the time, it returns false and the data is not synchronized. Sometimes it works, but not reliable.
There seems to be no problem with the internet connection - Auth and Storage works on the phone and a different phone in the same network can connect to the database just fine, so I think it has to do something with the phone. I'm testing with a Samsung XCover 3 (Lollipop, works) and a Wiko Sunset 2 (Kitkat, doesn't work).
The Wiko phone is really cheap, could that be a reason?
Are there any features to look deeper into firebase that could point me to the problem? The onCancelled method of my ValueEventListener doesn't get called and there are no log messages.
