Absolutely Worst Phone I Ever Had. SONY should be ashamed to release something so worthless.
Continuous small errors, flip-flops, Bluetooth that never works properly, wifi that clicks down whenever it wants, restarts and intermittent crashes.
The absolute biggest problem for me is Bluetooth. I use the phone a lot in the car and since it is now law that handsfree has to be used, it's embarrassing how bad BT works. It has, for example. Have the stereo in the car to crash and boot over. It's very exciting to see how it hurts every time you get in the car. Once upon a time, it refuses to disconnect, then switches it on, but the volume of music or conversation is reversed after 3sec. Next time, it plays music, but the sound is playing. After some time it works as it is supposed to be. The worst thing is that I can no longer return the shit to the store and because it works on simple BT devices, such as speakers, I can not even get a replacement for another device.
After a lot of applicants, I have found a large number of dissatisfied owners of xa1 ultra who have the same problem as I have. Some even worse.
That said, the phone has a great good display and low performance for the money.
I wanted a big screen phone, but did not want to pay 10,000kr for a phone.
But as usual, you get what you pay for.
Avoid this phone if you are using wifi or Bluetooth. Avoid!
