Hey there!
A possible solution to anyone's problem with Bluetooth drop outs might be to go into your settings in the phone and reset the Bluetooth/Wifi options and reset the Bluetooth settings, I'm not saying it's a 110% effective solution but if you haven't tried it yet it wouldn't hurt to try it you just have to re-pair any Bluetooth devices
I do hope it helps though if not sorry that's all I can think to try.
