Did the phone work properly when you first had it?
Have you ever used sony's "PC Companion" software (the program you install on your computer to connect the phone to the computer - for updates and backing up of contacts etc)?
The reason I ask is a lot of sony Xperia phones received an update during the summer/autumn this year and some people found that their phone started acting-up afterwards. In most cases, it's easily cured by running a "repair installation"...
PLEASE NOTE....
Running a repair install will wipe all of your saved information and return the phone to it's "out of the box" settings. You need to back-up things like contacts, text messages etc otherwise you will lose them. Depending on your settings, they may already be backed-up to your Google account - but double check if there's anything on the phone that you can't afford to lose.
To run a "Repair Installation"...
Run sony's PC Companion software on your pc/laptop - connect the phone to that computer via USB and wait for it to be recognised.
You'll be told that your phone is "up to date".
Click on the start button in the "Support Zone" section and a new window will open. In that window, click on the start button in the "Phone software update" section.
You'll get a pop-up message saying that your phone is upto date - at the bottom of that message you'll see "repair phone" written in blue - click on that and follow the instructions.
What this will do is reinstall the latest version of software on your phone and reset everything to defaults - this removes any apps or settings from an older software version that cause conflicts with the new version of Android.
It's not guaranteed to be the cure for all problems but it does work for a great many and it's easy to try - plus it's free and quick.
