Hi. I´m trying to use quick shot button with my Z3. Bought 2 days ago. I can feel to different "clicks" and on the first click it focusec pic but with the second it does nothing. It doesn´t open camera software when it is turned of. I have quick laund enabled so that ain´t the problem. Starting to feel that have to go to repair shop with this
You might want to take it to a Sony repair center
You can boot on safe mode
http://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/m-p/348008#U348008
and check if it works or not, if it does then its an app acting up
tried to repair software and with safe mode on, but not working
It could be a hardware issue, contact your local Xperia Care
I've exactly the same problem as Tolu. Tried everything and read all the comments above but nothing is working 
I'm having the same problem! Does anyone managed to correct this problem? I bought from ebay and I can't return it.
