So I got my Esteem laggy, exchanged it, got a nicer one with little lag. Got 1.5Mbps in Florida and it was cool.. a month later my speeds would never get over .30Mbps and for some weeks I had no 4G at all... that was ok, no biggie. But today I got a used Galaxy Indulged on the mail that I needed to send to my bro, but before doing it I decided to switch my account onto it just for the heck of it... And whatta u know... I get 3Mbps on that sucker... WTF man? lol It's still no biggie for me, but I'm curious as to why that would happen. Mind you, I never use any of those battery saving apps, because I read they give some 4G problems for some users.
