I have a Droid 4 running the latest Jelly Bean update. I am not rooted and I did do a factory reset after the update. Today, all of a sudden, I tried to download an app over data from the Play Store and it said "downloading" but it never downloaded the app. Also, I opened up Gmail and, when I tried to download an attachment, it wouldn't download either. Gmail would also not send or receive emails. Nothing seems to be wrong with my Google account. I have restarting the phone multiple times. I even cleared the cache and data and uninstalled updates for both of the apps and nothing is working. This is all over LTE, so I tried taking the SIM card out but that didn't work either. Any help?
