I've had the phone for about 10 days and I've consistently noticed that my G3 has a much weaker wifi signal than other phones, both at work and at home. At my house about 5 feet away from the router it was registering 1 bar on the 5Ghz network and about 2 or 3 bars on the 2.4 Ghz. Being that close to the router it should be full! The 5Ghz also has problems staying connected. At work where I used to have full bars with my GS4 and other phones and now I only get 1 or 2. While I haven't had the same problem as others with wifi dropping, it is rather annoying that the signal is so much weaker and I have noticed that with the reduced signal strength my connections are slower. I really hope its a software issue and not hardware related. I'm seriously thinking about going to T-Mobile and asking them to look into it.
