For clarity, I am in the UK and have an unlocked unbranded UK phone. Hopefully the update is in its way to you soon.
So. Far so good. Battery seems great. Just approaching 4 hours SOT today with 55% battery left. I had a problem where my phone Bluetooth disconnected from my car today whilst driving which has never happened before. Could be phone, may have been an issue with car but will keep an eye on it.
