I've had Motorola Droid Razr Maxx for few months ago. In Rochester, NY, it has 4G LTE coverage. Now I am at home in Portsmouth, VA and there have 4G LTE coverage but few days ago, it now 3G for forever. I tried to relocate the nearby 4G LTE tower, it said its still 3G at full bar. The mobile network setting, it said global but I changed to CDMA/LTE. Still no luck
The android version is 4.0.4. Before I upgrade, its 4G LTE but after that, it staying 3G.
