The best way I found to easily unlock my phone is to just have a password that can easily be pressed in. For example I had mine for awhile BNM$, so that I can just move my finger across from left to right and the last thing I push on that same lane is enter.
Although it isnt the most secure, it will atleast will keep nosey people out of my phone since it is such an obvious password and stupid password people wouldnt think of it. ;)
Atleast thats what Im banking on
