It has been brought to our attention that some early adopters of the Motorola Droid Bionic are having signal issues causing an ongoing switch between 3G, 4G, and no signal at all. (My Bionic was defective out of the box and wouldn’t even activate). It has been reported that the constant switch between radios can decrease battery life to under 6 hours with only minimal use. Since the Bionic is such a new device, Verizon may not even know that some phones are experiencing this issue.
If you are having radio problems it’s a good idea to contact your local retailer or customer service rep to seek out a possible replacement. You are still within your “14 day worry free guarantee” and should have no problems getting a new Bionic. Enough reports have surfaced on the interweb to deem that this might just be an actual defect.
