I had an epic 4G when it came out and maybe 3-4 months in, for no reason at all the 4G sysmbol would not appear/nor could u turn it on at all. Go to Sprint and they issue me a new phone. All is well, got the OTA 2.1 and had alittle problem at first, but worked it out and everything has been amazing....untill a few days ago. This time the 4G is there, but im not getting 4G speeds at all. My average speed using testmy.net and seedtest.com were about 900 kB/s. Now i get between 35 and 45 kB/s. So ive been instructed to go back again to my sprint store. Has anyone els had this problem? This is 2 phones now? I do turn 4G off and on alot because where i work i get no 4G service and it kills the battery. other than that the phone is in perfect shape. And up untill a few days ago was running fine. So it wasnt the update. I hate sprint, if the epic were on another carrier id be there in a heartbeat! Love the keyboard with the AMOLED screen. So, has anyone had problems like this?
