[Q] Changing the camera app in the lockscreen?

view story

http://forum.xda-developers.com – Hi, I'm running Android 4.2.2 (RomAur) on my Xperia Z. When I first configured the lockscreen, I defined the Sony camera applicaition as the camera to use on the lockscreen. Since, I have installed the JB 4.3 camera application and would prefer to use this one, as it starts faster. However I cannot find where I can change the camera application used by the lockscreen. I tried freezing the Sony app with Titanium Backup but the lockscreen does not ask back for another camera app, it just doesn't do anything. I found in TB a "Lockscreen" application. I deleted the data for t (HowTos)
