My signal has gone to crap - I thought it was my new One M7, but my wife's S4 is exhibiting the same behavior...can't help but think something is wrong, as I used to get a solid 4G signal at home a few months ago on my ReZound.
I live just off a major state highway, I am in town, and right in the middle of the 4G coverage for Verizon (there's 6 towers within 4 miles of my house, and 17 antennas - according to antennasearch.com). The local Verizon tech pulled their map and said I should be getting full signal at my house.
Despite all this, when I get within a mile from my house coming in fr the East on the state hwy, I drop to 1 bar of 3G and lose all data. At home, I switch between these signals:
(rare) 4G RSRP -120 to -123 dBm
3G (eHRPD) -110 to -118 dBm
1 1xRTT -97 dBm
If I go another half mile west in town (which is flat land), I am back to sub -100 signal on 4G. Any way to get someone to actually investigate and do something about it?
