Locking apps in place

[Guest mytonpadi]

How do I lock or prevent apps from accidentally moving it from its designated location?

 

Second. how do I rename my bluetooth device?

[Guest SH3H1]

First question didn't understand.:huh::huh:

Go to settings > bluetooth > on.

After it is on press options(right on of the three buttons) and select rename phone.

Give name and enjoy.....:D

Hope helped

Use any after market launcher (Apex, nova, holo etc) to lock your home screen.
