I bought a Captivate this morning. It is pretty sweeeet. There is an odd thing happening though. On several occassions, when I am doing something, the phone will give a quick vibrate and close out whatever I was doing. I orginally thought I had touched the 'Back button', but a few times I am sure I didn't touch something worng. For example, I opened up my 'Contacts' and it showed for about 1/2 second, the phone vibrated and sent me back to Home. Everytime I go the Market, I will get this happenening. Busted phone or am I missing something ? Help !!!
