Houston I figured out the problem!!!

Ok, so as most of you already know my phone is crazy... I figured it out though! After being yelled at for scaring someone(who shall remain nameless) by calling someone at 4am without saying anything, and having him call me at 6 am and wake me up because I called him for like 2 hours....I had to figure it out! Now it's effecting my sleep.... Not good, Not good... One, the phone was in my purse and in my pocket for only brief moments earlier on but even when I had it plugged into the wall last night sleeping, it was doing it. The phone however was still in the bed but face down or had the TV remote touching the top of the keyboard. It seems this only happens when something is touching the keyboard and the phone isn't locked. One, I have to always remember to lock my phone when I am not on it. Two, when it is not locked it is either calling people in my speed dials or recent call log....(I am a little unsure about this one) I am not sure why this is going on all of a sudden but I am going to get a new phone, I just have to have time to get it done.... I will just have to make sure that until then, I just keep my phone locked... Sorry peoples
