After today's official launch of the Samsung Vibrant, we've been receiving a good amount of complaints from Vibrant owners regarding reception degradation. Vibrant owners seem to be experiencing issues similar to the iPhone 4's infamous "Death Grip". As demonstrated in the video above, tightly gripping the handset results in signal loss and often negatively affects data speeds. We're not sure if this is a hardware or software related issue, but we're hoping it's the latter. Any Vibrant owners out there experiencing this issue?
