Any other mobile and my iPad is working flawless with my Sony HT RT3 except my Xperia xa dual. Connection lost automatically after few minutes of bluetooth audio connection . After that it takes ages to find the device again. Sound plays well for few minutes, then stuttering begins & there is no way to avoid this except restarting the device or disconnect and connect again . Don't know whats going on, Its really a pain. I have no options except buying a new phone. Worst experience never buy sony mobile again.
