I bought the GPE and had to return it. I had the same issues with data reception. Where I had two bars of LTE with other phones I had nothing with the GPE. It would lose the signal and then have it. It was very maddening. Too bad because I had an unlocked Rogers z10 on ATT and the reception was perfect even though it was a Rogers phone. I am not sure why I have such issue with Nexus and GPE phones.
