Because Verizon service sucks in my own neighborhood, they sold me a 3G signal booster back when I had the original Droid. It worked fine on my Nexus until the Jelly Bean update and now I get a big, fat "R" over my signal bar whenever I'm at home. My brother with a Nexus also got the "R" when he walked into my house. The "R" followed me to work, and the only way I could get it off of roaming was to pull the battery and the SIM and reboot. When I returned home, the "R" returned. Anyone having this problem but me?
