OK so i just got my DX a little over a week ago. i do NOT get many calls at all...i have gotten maybe 10 calls since i got it. but i noticed, it seems like ever other call, i get a button to answer a call instead of the slider to answer. what is going on here? i actually prefer the button, is there any way i can lock that in and get rid of the slider? I had the original Droid before and never had the button to push....so i am guessing this is a Blur feature...just wondering how it worked and when the button gets displayed. any help/insight would be appreciated.
