My Xperia Z2 phone prompted me to update to 17.1.A.2.69 and it has disabled LTE and defaulted everything to 4G. How do I get LTE back active?
I've seen other comments about this issue on the Xperia Z2 Tablet forum from Xperia Z2 phone owners.
4G=LTE,it is just the naming that differs.
Usually it be fixed by the next update. Which is scheduled to be out soon.
LTE & 4G is the same thing.
