also some apps uses sensors ..so to get these apps to work  u should have that sensor

2. tap tap app

but personally i suggest u to practice with the proximity sensor...some users have problem with that...

3. SPoB

because some users finds it annoying !!

fix power button has that option to prevent the lock screen appearing.
