I been playing with my recently delivered refurbished UB2 LTE and used it on a long phone call. Immediately the watch got warm on my wrist then hung up on me after 40 minutes.
I then see the message.

Anyone else have this? Otherwise I might have a dud unit.
It also periodically disconnects BT and Wifi and goes onto LTE.
