I have been experiencing an issue (albeit small) with 4G/LTE switching. Wondering if it's my phone or if others experience it too. Detroit just got LTE before the iPhone 5 released...so maybe it's a "newer network" issue. Typically, I have no issue & I'm on LTE. However, from time to time, I'll hit a dead spot or something and my phone will go to 4G. When I get back to a known LTE area...like my house...it doesn't always switch back to LTE unless I quickly go in & out of airplane mode. After that, it goes directly back to LTE. Anyone else have this issue?
