I also have noticed a significant drop in signal strength the last few months. Now I get 1 or 2 bars in and out of house. I have a Samsung S7 Edge. zip 29909
Some time ago, we had a significant drop in signal in our home. Basically, our we couldn't use our phones for calls. Nearly all incoming and outgoing calls dropped. We got a Network Extender from VZW which helped. Now, with phones having wifi calling capability, the network strength is a nonissue.
