I have the same problem on my XZ1 compact when paired to my Plantronics BT headset, it kept disconnecting and reconnecting the next second. Sometimes the BT would show that is is connected but when i make a call, it isn't connected to the BT headset. I emailed support and follow their instructions below and still have the same problem, anybody experiencing the same? Hope there is a solution to fix this problem soon.
Thank you for contacting the Sony Xperia support centre.
