    My phone (att) drops LTE to 4G whenever even a call rings or I pick up, and is slow to reconnect when the call is done.

    I can speed it up by going to settings and disabling and enabling LTE. What gives?? Is this a limitation we will always have or is this a iOS software issue?

    I've also noticed this. I usually toggle the airplane mode on/off

    This is normal. All calls drop data from lte to hspa/3G.

    Current chipsets cannot handle lte data and 3G wccdma calling.

    Android Verizon phones use 2 chipsets so can maintain CDMA voice and lte data.

    The snapdragon s4 actually can do both using just one chip. :eek:

    Normal, fine, but why so long to reconnect to LTE on its own vs me manually doing it, doesn't make sense, surely that is a iOS limitation that can be fixed with an update??

    It's been discussed in numerous threads already. How hard is to use search?
