Hi !!
I am having this strange problem. When I restart the phone for first 2-3 hours if I click on settings it asks for security password. Although after 2-3 hours it stops asking for one but I am sure I havent set any passwords. The default passwords like 1111, 0000 etc wont work. I mailed sony care but there response is still pending. I dont wanna reset phone and spend time setting up all the things again
. Can anyone suggest a solution? I am attaching a screenshot of the same.
Solved! Go to Solution.
This is odd, do you have a SIM lock? is it a PUK password/pin?
Nope... No lock. And if there would be one then why just for 2-3 hours?? 
You might have to reset your phone, you have to use SUS
Update Service (SUS)

Glad to hear it worked for you
Can you help me with the process?? how can I avoid re-downloading heavy apps??
Just read the steps above, you will have to redownload all your apps
So did the problem get solved or you had to download everything again? Am facing the same problem though in my case it asks for password all the time
Have you tried the steps outlined by Uliwooly? If the phone is locked and you can’t get in you will need to run a repair as per the steps provided above.
