Just got a DROID RAZR MAXX today (upgraded from the original DROID A855 which I had for 3 years!). I set the screen lock with a PIN, but when the phone goes into sleep mode or the display timeout takes affect and I reactivate it, it just slides to open and never prompts for the PIN. I tried toggling it off and then back on (the screen lock feature), and I even tried a pattern and password. Still not working. What am I missing? It always worked perfectly on my other DROID. I've gone through the User Guide many times and did multiple Google searches but can't find anyone having this same issue. I just don't understand what I could be doing wrong? Thanx in advance! Edited to add: I just powered the phone off (for the first time!) and when I powered it back on and slid to open, it prompted for the PIN. Is that the only way it works? I cannot set it so the PIN has to be entered upon it returning from screen timeout? How do I keep others from accessing my phone??
