I am always pressing numbers or buttons on my phone and sometimes i forget to lock it and there i go calling someone and i don't even know. well with this phone when you are done using it it automatically locks itself so you won;t be calling anyone or pushing numbers and acidentlly call 911. Another great feature on this phone is that it has gps and it is right on where you want to go and how to get there. So i would recommend this phone and it is the latest technology so if you are one of those that wants the newest here you go!
