Let me first reference this related thread: http://androidforums.com/samsung-ga...-seeing-signal-bars-completely-disappear.html I am having very poor signal strength with my Galaxy Nexus. At home I get only 1 bar even if I go outside. I am not far from a tower. Downtown, if I go into a building, I get no signal. My calls are often dropped to the extent that I cannot even make a phone call. I Googled this and there are many others with the same complaint. I finally called Verizon support and after numerous tests, they sent me a new sim card. It made no difference. I have discovered that in order to see 4G I have to turn off Wi-Fi. One person said this phone has known problems with its poor radio and to insist Verizon exchange it for a RAZR Max. Any thoughts or help?
