Upgraded from Incredible to rezound approx 2 wks ago. I noticed that I had the wifi & 4g connections signals were not that strong. After checking the values at various locations in the house I determined that the signal strengths varied from phone on the table to phone in hand in the same position. The difference was -10 to -12 dbn on wifi (per meter) and 2 bars on phone 4g. Should holding the phone in your hand block that much signal? I noticed some gold tape inside the back cover, is that the antenna? Has anyone else noticed this degraded signal problem. Is there a fix?
