Reasons why you lose Mobile Data signal....is its REALLY your phone? Likely NOT.
So with all the gripes going on about the Gnex and losing mobile data, etc..I thought I would share this.
My opinion is this. A LOT of folks were waiting for the Gnex to release...and holding on to their upgrades to move to that phone. Many of these folks were on 3g devices previously which handles data differently than LTE technology. Im sure folks were used to staying connected on 3g and not getting interruptions in service. Well...that doesnt seem to be the case with most of the LTE phones. Now...before you go posting stuff like (I have a rezound/razr...and I get better signal and data than I did on my gnex). Or better yet...the infamous "I dont have a problem so there must not really be one" posts. Spare us.
Seems like your Gnex not getting data sometimes is not necessarily the radio or the reciever on the phone...nor the reception ability of the phone (that could be another issue), but more so with the "authentication" of your device failing on Verizon's end trying to connect to their network. So before you start with the, "if the 4.0.3 radio doesnt help, im ditching the phone" shenanigans...consider that your device may actually NOT be the problem.
Here is an interesting read on how LTE handles data and your device "checking in" and getting kicked off when stagnate for a while.
