The screen is way too sensitive, hovering my fingers on the screen can even be registered as a touch. it was annoying at the beginning but now I'm getting used to it.
I got the Australian version of Xperia Z2. While a lot of countries have already got updated to 17.1.1, mine is still sitting at 17.1. I had to backup the phone and then flash the German firmware myself. I could not understand why don't Sony just simply release the update worldwide at once and everyone will be happy!
I backed up the phone via Sony companion. However, when I tried to restore all my contents...Guess what? First try, it stuck in the middle and progress indicator did not move for hours. Second time, I had to untick the 'others' to let it at least finish the restore, which means all my app data could not be restored. Even after that, it still couldn't get the job done properly. After the restore was finished, the app was telling me my contacts and settings cannot be restored. Third time, messages restore was successful, but settings and messages cannot be restored...the funny thing is, messages were successfully restored during the second time, but failed in the third time...I just...grrrrrrrr! Finally I gave up and decided to set up every thing on my phone manually after wasting my whole day on this. (If you know any backup app that works well, please let me know. the Sony one is absolutely pathetic!)
Also, I cannot seem to get the MP4 files to play properly on my phone, they have no sound for whatever reason.
While I enjoy the active noise cancelling without dragging an extra brick around, I don't really think I will get another Sony or any android phone when I upgrade next time.
