Can you tell us what modem you are using that gives you faster speeds and stronger signal? I was on both stock and multiple custom ROMs of MJ4 and I got way better signal strength and speeds than I do with NAB, and I'm running Sacs NAB ROM. I haven't flashed any other mod either, it's just Sacs. I was thinking of doing Carbon's AOSP ROM and seeing if I can get stock samsung apps (like camera, TW, just the basics, no bloatware) to work. I just personally like TW and like the features that the camera has (even though I've never, even out of the box, been able to get drama to work). I love the speed of AOSP and the minimal disk footprint, I just prefer some, SOME, of the samsung apps. But my main pain point right now with any NAB (4.4.2) ROM, stock or custom, is my signal got worse. Yes, I work on the Sprint campus so of course my nation wide clear coverage is non-existent (I'm lucky to get two bars of 3G, much less the LTE speed that Verizon or AT&T users ON THE SPRINT CAMPUS get to enjoy, sprint fail, I digress). Anywho, at home when I was on MJ4, I was getting download speeds of 15 Mb and upload speeds of around 6 Mb. Now with NAB I'm getting 5 Mb download speeds and 7.5 Mb upload speeds! Tell me how that works??? Maybe that's why battery life is so good for me, because I'm not connecting to the network so it's not using battery to communicate. I doubt it, but it sounded good at the time. So if you have a modem that you can point me to so I can flash it to get the better signal and speed, I'd be really appreciative.
