I'm using Android 4.1.2 on Xperia Arc S. I have 3 problems:
1) Whenever I want to play the video I recorded, there's the message: "Video playback error! Sorry, the selected video format cannot be played". I can transfer the file to computer, though, where it plays fine.
2) Whenever I want to install .apk file (non Google Store) there's the message: "Parse error. There is a problem parsing the package". I've turned on "Unknown sources", and those apk application are meant for Android 4.1.2, but the problem is still there.
3) Whenever I use mobile network to go to internet, the kb/s indicator at the top of the screen uses internet even though I'm not using Mini Opera. I'm not interested in synchronizing my internet accounts with the phone, I just want to surf the net via Opera, but I'm losing pre-paid money credit fast this way, even while not browsing. How can I turn off everything in the background, so only the Opera uses internet?
