Hello!

After upgrading to 7.1.1 there were problems work problems:

1. When you receive a call there is sound and vibration but screen does not light up until you turn it on with the button.
2. When connecting to the audio system in the car via Bt, the music information is not displayed in the car, she used to appear on the previous version of the software.
3. Most importantly, the phone has a very large consumption of RAM, so many features do not work correctly and the camera may not correctly used in most cases,often the gap between the press and photography about 10 seconds

Please improve the system!

Unforntunately those are known issues, we just have to wait for sony to fix these 7.1.1 problems...

The main thing is that now I realized that I'm not alone but seriously, there is no longer any power to use the phone. He can not cope with his functions ... We will wait, but the desire to buy drowsies is no longer there

OH! I've just discovered most XZ users face the same problem.

I found the phone lagging so much after the system upgrade about 2 weeks ago, and I've just found that the RAM consumption is more than 50% which were not before the upgrade.

Don't know how long we have to wait for the Sony to fix this problem?

The latest system update (41.2.A.7.35 as of July 13th, 2017) hasn't fixed the BT issue at all. Additionally, a couple of Apps, that are running smoothly on other smartphones (e. g. Twitter) do not work at all on my XZ. I have experienced the delay during shooting photos as well. On the other hand, it seems to me, that the endurance of the accumulator has become better due to seemingly lower power consumption.
