Just moved up from a Note9, used the switching software.
However my music and others time out with the screen sleep setting, which only has a max of 10 mins (iirc), This is very irritating when listening to a piece of music via Bluetooth, and it stops.
There must be a setting somewhere to change this but I can't find it on the phone, or in the apps settings.
Probably get a better range of solutions by Googling something like or variants of "A55 change timeout settings for sleep settings". Also you may find an app in Play Store which has a work around (you are not the only one with this problem). You will find something relevant if you go to main Community page, top right, search for terms like "sleep settings", "timeout", etc.
