Camera defective?

[aajj99]

Have Xperia Tablet Z (wifi) since June, running 4.1.2, rooted.   Did not upgrade, waiting for KitKat.

Camera was working fine for both images & video.   Now taking photos stopped working, but video is fine.     To be more clear, video works whether in image mode OR video mode.    Switching back & forth between the 2 icons does not fix it; cannot take still image photos.

 Is there a way to uninstall/reinstall camera app?    Is it a hardware issue?    Is it a software issue?

I really don't want to bring it in & leave it for repair for weeks/months.

Any help & guidance is greatly appreciated
