Xperia first page doesn't work

[BBz]

I can not use the Xperia first page and I ise the regular one, this ugly page. Everytime i try to open it never does

[BBz]

Either it slowly slowly opens the contacts or the sms or it freezes.when it is locked and can not unlock.it i have to remove the sim card to.reopen.the phone. Have not tried to reset the phone as I am.afraid that i will.lose some data. Would u think restart would.help or something else?

Consider performing a system repair as this will often fix issues - This will factory reset your phone

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the onscreen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP
