Audio only working out of 1 ear on earphones after September security patch.

After most recent update in Ireland, (the September security patch). My earphone started to only work out of the right ear. I did the update today and all before that my earphones audio used to work perfectly  so im nearly sure it's not the jack.

Must bea coincidence.

Try your earbuds on another phone and try other earbuds on your phone to check if it is phone or earbuds.
