Samsung SPH-i700 Smartphone

I have had this phone for about a month now. There is so much to learn about it. I had it connected to the internet but it was extremely slow and I couldn't get it to do what I wanted it to so I disconnected it. The reason I titled this review possessed is that it has on several occasions phoned the last person I spoke with seemingly on its own. I will hear someone saying hello and answer the phone and they say I called. My previous phone was a Kyocera clam PDA which I loved. If you bump this one and the talk button is pressed, it will place a call. One of my friends had 6 calls from me which I never placed (at least not intentionally). There is probably a way to turn this feature off without turning the phone off but I haven't discovered it yet.
