Hello...I was looking into maxis offer....S4, LTE vs non LTE...what are the differences between these phones...other than the specs....I'm new into androids, please help explain the difference in layman's term....appreciate it.

help help....bought S4 LTE 3 weeks ago.
problem started in week 1...the phone shut down by itself when idle for a while, sometimes the phone also shutdown when charging. Initially went back to dealer (Maxis center) they say they can't diagnose the problem. Then went to Samsung federal highway, they upgraded my software....but still happening....it was rather warm when charging though, warmer then my ipad...is it normal, any advice, please direct!!

with reference to my earlier problem.....shutdown suddenly when idle....what's the difference if i'm having microSD....but i'm not having microSD....been to the samsung center.....the people there are not really helpful.....giving me hundred of reasons...ask me to go back if got problem then they will take next step....

feel like really banging their table and shout loud loud....buy phone bundled with problems!!!! then nanti got caught in a video and posted in youtube pula!
