So im at my APN settings but everything is gray out I've heard people say change APN protocol to IPv6 to IPv4 since i have horrible LTE Speeds my s4 was great and so was the 5s now the note 3 has real bad LTE (also wifi...) so how can I change it?
I've tried all apn settings, v4, v6 & epc, they all produce the same speeds & latency for me on sgn2 & 3, I like to keep it on v4 because I come across some pages that are not v6 compatible yet. So I hope that helps, at least for the southern cali folks.
