does it only happen at your house? it might not be the phone
i havent had any issues with mine, but i'm in a major city
It is the worst at my house (town population is 10,000,) but I've recently noticed a huge deficiency in signal strength in other areas that used to get signal as well. I regularly drive 90 miles round trip for work inside a Verizon 3G map. I get data, but little to no phone signal. In a lot of areas I get as high as 3 bars, but it's unstable. The other day I drove another 50 miles away from that 90 mile route en route to a 100,000 population city (to visit a Verizon store) and completely lost phone signal just 15 miles before the city. The Verizon reps told me that the bars mean nothing (????)
The first week I had the phone, I was on vacation in a major vacation area 4 hours from home and I got 4G LTE and 5 bars. Since then I can still get 4G from time to time, and 3G pretty consistently, but the signal only improves sporadically in tiny patches.
With the way some people are responding, I really just think this phone has a weak antenna. People in larger cities have no problem whatsoever, and that would make sense if they have radio towers all around them. More power to ya.
Signal bars are merely a visual indicator. It's not so much that they mean "nothing", but comparing 4 bars on SGSIII to 4 bars on my Rezound doesn't necessarily mean they are receiving the same signal, to get a true comparison, you have to compare dBm.
