Restricting a check from being deposited via cell phone
I don't see any reason to worry about a check being deposited via cell phone. There isn't anything you can write on a check to make it physical deposit only or similar.  If you really want to keep your check from being read electronically you could always smudge the numbers but you run the risk of the bank not cashing it and possibly getting a return check fee.
