I know the Bionic has had issues from the start with 4g authentication, and it seems to be hit or miss depending on the phone. Mine has always been flawless until just recently, at which time it started to give me the dreaded "ghostbusters" red circle on the radio with no bars. It would occasionally connect on 4g but would disconnect over and over and was very unreliable, more often than not it would not even fall back to 3g and just give me the dead radio icon. If I change it to 3g using LTEOnOff app it works flawlessly. My wife has a Bionic also, same exact everything, and she does not have these issues. I am rooted on 4.1.2 but have flashed other roms into safestrap with no success curing the 4g problem. Just wondering if anyone ever discovered a sure-fire cure to get the 4g working again.

Re: 4g Authentication
Thanks for the reply. I've done the airplane mode "trick," turned the radio on and off and set various modes with LTEOnOff, taken the battery and sim out, and I've even done a reset with the installation of a new custom ROM. Nothing has worked. We are in Houston and the coverage is strong. My wife's bionic gets nearly full bars on 4g at all times, while mine (side by side with hers) refuses to authenticate most of the time. I've researched this online extensively and the only thing I've seen that may work is a new SIM, but even then there are those saying it does not work for them. Was just wondering if anyone had found out the actual residual cause for this 4g issue (been ongoing for years on Verizon network) and if there was a reliable cure. I found a few sites stating it is an authentication issue, and that it affects certain models of phones more than others.

Re: 4g Authentication
Yeah, I thought about it being broke but sometimes it does connect, just not for long. It is so unreliable I just leave it on 3g, but I've had days where it would connect flawlessly all day, then the next day completely borked. So maybe you are right, time for a new phone. I may go get a new SIM just for kicks - do I have to do a full factory reset if I activate a new SIM in the phone?
