I'm having a bizarre problem. My droid has been great since I got it in February but for the past 4-5 days, I've had terrible (zero) reception in places I've always had great reception - specifically, my apartment, my office, and my girlfriends apartment. My bars sporadically switch from no signal, to one bar of 1x, to back to no signal. If I'm lucky, I will have about a 5 second period of full 3G reception like I used to, but then it will switch back to no bars. Now if I'm on the first floor of a building, or if I'm anywhere outside, there is no problem whatsoever and I get perfect reception. But I've noticed that if I'm anywhere above or below ground in a building, boom, there go my bars. I live in the DC metro area, btw and am running 2.1-update1....this has never happened before, prior to about a week ago. I took my phone to verizon and also called technical support. Thus far I've tried the following things: 1) Battery pull 2) *228, option 1 (reactivating phone) 3) *228, option 2 (updating cell phone tower?) 4) Factory reset None of this helps. And since verizon cant replicate my problem in store, i've pretty much been told that theres nothing they can do. So...my questions are: anyone else having this problem? is it the phone or the cell phone towers? and are there any other known solutions? Any help would be appreciated. I basically have a great piece of hardware that only works outdoors now! Thanks.
