How to prevent accidental launch of Camera app from lock screen? I have an Archos Helium 50 phone running Android 4.3. It often activates the Camera app while the phone is still in my pocket. Plus, since it's dark inside my pocket, it activates the flash &mdash; this drains a lot of battery.

I tried to disable it but I didn't find any option in the menus which would allow me to do so. What can I try?  Did I miss some hidden menu?

Please note that the phone is not rooted; I absolutely refuse to root it.
Try Lock Screen Policy App and disable the Camera.



Disable multiple 3rd party widgets on the lockscreen. Also removes lockscreen camera access on some devices
