Catch back key event to avoid app exit

Dear all,

Is there a way to catch the back key press event so that when we press the back key of the phone, the app does not exit?

When navigating through an app, for example when viewing an enlarged image, pressing the back key results in app exit, instead of being back to the previous screen containing the image.

Any video and precision required, pls let me know!

Cheers Gliders
