Careful about your touchscreen phone

[amirm]

A bit of Amir CSI for you on this Monday morning .

I picked up my phone this morning and noticed something: There is grease, smudge that perfectly matches my unlock code for the phone! No wonder. You keep unlocking it that way so a semi-permanent pattern gets imprinted on it.

A wipe against my cloths removed it. Good thing to do from time to time!

Yes. I stopped using that style of lock because of that. Also, people have an uncanny ability to pick up on the pattern.

Same thing can happen with your house alarm touchpad, FYI. Gives the bad folk a real help...
