Just realized that even though it says I have 2 dots of LTE, I really have no connection at all. I'll go awhile with no notifications and then all of a sudden, boom I get a bunch, some of which are old. This is really getting annoying.
I had the same issue today while driving around town. Phone was switching from LTE to 3G/1x/No Service a ton. At one point the phone was claiming I had a decent LTE signal, yet I couldn't do anything requiring data. I had to reboot the phone to get service back.
This is getting ridiculous.
