That's fair. I get
rare double locks. With the earlier solution I got them constantly (100% of the time, no fail) - it was driving me insane. Because I'd unlock the phone, then wait to see if it double locked, and then when I thought I was safe enough to do anything else it would lock again.
I have the incall lock on and haven't tried turning it off yet. I will keep experimenting. There are more recent versions of that program, but I worry about feature creep. No one makes a simple locking program that just works without adding a bunch of other crap (unlock when music playing, light sensors, etc.)
Sorry that it's not the ultimate solution....by the time I find it I'll have switched phones.
Edit: decided I'm going to try pocketshield again...will update with results. That was really the only solution for the touch pro
