FM radio not playing in background?

[Jenni Phillips]

I'm not entirely technically minded, but from what I understand my S2 updated last week, so now it says it has android 4.1.2.

However, it now will not play the FM radio (using the original app that came with the phone) in the background - so I can't do anything else on the phone whilst listening to the radio. Prior to the update it would just play whilst I did other things on the phone. Does anyone know how I can fix this?

Thanks

EDIT: did a factory reset and the problem resolved itself.
