I've had two bionics now and I noticed a difference in 4g from both of them. With my first one, I had constant 4g signal and almost never lost connectivity.
With my new one, I would get low 4g signal. Also, at work I would get 4g signal with my first one. Now my second one never gets 4g signal there at all unless I toggle the airplane mode. And even then, the 4g wouldn't last long and eventually switch back to 3g. I'm desperately hoping this will be fixed in the update. But it seems that this issue is not consistent with all bionics.
