I've recently updated to Android 10 on my XZ2 Compact; I wish I hadn't.
The fingerprint reader is really slow and sometimes even unresponsive since the update. I also notice a significant drop in performance when the phone is on for a few hours, forcing me to restart the device. I did not have to do this before the Android 10 update.
All in all I do not recommend anyone to update and I want Sony to fix these problems. I wonder how this went through Q&A.
