Hello,

Can someone help me, i have a problem which is on android 4.4, its the camera, it continously freezes when i try to take a picture, has anyone else got this problem?

Can someone help me on how to downgrade my software from 4.4 to 4.3 please?

if not could you help me on how to fix the camera problem?

I have tried to repair my phone, this did not work

Thanks

You first need a .ftf firmware file from here

Then follow this guide here - Ignore the title as it's the process you need to follow simply use the firmware from above instead of the Xperia S firmware listed but everything else is the same in regards to Flashtools etc

Which one do i download? is it hard to do and how long will it take? is it risky?

Hi you can unlock your bootloader and flash custom from Trinity and flash custom kernel from Trinity. Now camera works fine! Sony please pay attantion that problem with camera on Z1/Z2 can be resolved if you change your stock kernel on another stable kernel! http://forum.xda-developers.com/xperia-z1/development/ub-trinity-vengeance-raptorx-v1-0-t2838835

Is that safe as well?
