Thank you for the update 11.2.A.0.21
The mobile is slightly faster and more stable.
However, I hope that the front memera will be absolutely fixed after upgrade but it seems not completely fixed yet, still has same problem as I noticed before in this forum

It's fine when using in bright place but the camera cannot adjust the brightness itself when use in low light, the brightness of picture in display will dimmer by light condition accordingly.
Please see comparison pictures in this link. I compare the picture from front camera both XP mini pro and XP J
