My new RAZR Maxx HD will work fine for most of the day and then I will go to check my e-mail or go online and it just sits there and thinks and the arrows by the 4g don't light up. No matter what I try that is internet related (mail, internet browsing, etc) will not work. If I put the phone on airplane mode and then switch back then it will work fine. I went into settings and changed the network mode setting from global to LTE/CDMA, got a new sim card, did a factory reset and it still does it about once a day. Is anyone else having this issue?
