I keep getting a warning message that I can't connect to the Verizon Cloud service & to check my data connection. But I'm on my home wi-fi and this just started happening a few days ago. Also, my battery drains like crazy and I've done multiple things to try to limit the battery usage but nothing works. Thirdly, my data usage has skyrocketed over the past two months (basically since I upgraded my phone). What gives?
