I have a samsung a15 5g and wanted to connect two Bluetooth devices for dual audio, but I can't find any options for that.......if my device does not support this freature, its there any other method to make this work??

Soo, i am some problems with my Samsung A15 5G. I wanted to clear my cache using "wipe cache partition." But I am unable to do so because I can't open recovery mode... I tried volume up + power, volume down + power, and also all three buttons! But no...
