Hi,
My iPhone 5 is exhibiting odd behavior with LTE.
Firstly, the signal is extremely weak. I am in NYC. In my office where I have 4-5 bars of 3G, I have barely 1 bar of LTE. My office has a huge window and is not obstructed by other buildings. The building is glass. It's also odd because not only is the signal weak, but after resetting network settings the signal will be 5 bars on LTE and gradually decrease to 1. When moving through areas where I had no service (say, the elevator) and then entering my office, my phone will quickly pick up the 3G signal, but then take several MINUTES to realize there's LTE available. This also doesn't happen just in my office - it happens on the street as well. Walking out of the elevator onto the street, 3G service picks up quickly. It takes the phone a few minutes to realize LTE is available and get a signal. Yet if I toggle airplane mode on and off the phone will pick up the LTE signal immediately.
Secondly, it seems like the phone is "shutting off" LTE when the phone is inactive. This is affecting me in numerous ways, including iMessage. When not actively using the phone there will be gaps in my messages, and a bunch of them will come through as texts, meaning the phone on the other end didn't think my phone was available for iMessage even though I have service. Yet when I reply and am actively messaging/using the phone, all messages are iMessages, not text, because the data connection is active again.
(Note: these issues are not the same as the lag that people were experiencing)
Any help would be greatly appreciated.
