For those that have music cut off via Spotify one
try these.......
I remember very clearly that when i first got the phone
the Spotify is working flawlessly
then suddenly
when i listen to Spotify via Bluetooth earphone
the music will cut off when the phone blank out
and will resume when you tap on the screen
i remember i change a lot of settings on my phone
and mostly to do with Battery Saving.....
in my Battery Settings,,.. i make sure Spotify is not in the Disabled Apps or Sleeping apps
Adaptive battery : turn off
Put unused apps to sleep turned off
Optimize Settings turn off
Power mode is Optimized
it is working
i am not 100% sure which settings above that causes it
but it is not the music streaming apps issue
it is Samsung's battery saving issue
