Apparently my 4g no longer works the way it's supposed to. When i tap the 4g icon, it just says "on" then after a min, it flips back to off. Normally i would see a "4g is disconnected" message on the status bar at the top of the screen.
I'm in silver spring, MD. There was 4g coverage previously and i'm having trouble finding information on how to test the hardware settings on my phone.
I can do a hard reset but that is an absolute last resort.
My co-worker had the same problem over the weekend....I had her pull her battery and restart the phone then update her PRL which bascially pings her near-by towers and updates them on the phone.....maybe or may not but worth the try....hers works fine now
Both mine and my wife's phones did that (see the thread called "4G doesn't work after DI07 update"). All of the people who had this problem had to get their phones replaced as no fix could resolve the problem.
If you are within your 30 days you should get a new one. But I wouldn't worry about a refurb phone as long as it works. I've had Refurbs before and they look exactly like new...at least you can be sure it will work.
i'm on my 4th epic. 2 of them, the capacative buttons were flaky. one had a crappy gps lock (i'd be in Silver Spring, MD while the phone was telling me i was in St Louis), then this one, which i've had only for 6 weeks, the 4g hardware failure. This is why i'm pushing for a new one instead of a refurb. maybe i'm greedy, but for all the trouble i've gone through, i thought Sprint would at least give me a new one instead of a refurbished one. I just feel better knowing a new one out of the box that hasn't been accidentally dropped, or damaged for some reason as opposed to one that hasnt experienced any issues. if Samsung had the quality of refurbished Apple products, i'd go for it. But at this point, i'm tempted to just go back to the Evo. At least it's got froyo, and better support. The only thing that's making me keep the Samsung is they're better for those who use hearing aids. I'm hard of hearing and the ratings are better on the Samsung than they are on the Evo phones.
Just use the pull down bar and touch the 4G button it should eventually turn GREEN. If it tries to turn on then doesn't, it won't even search for a 4G signal. If you are NOT in a 4G area the button should stay Green even though you are "disconnected" from the 4G network. If the button does not go green at all, go to settings/wireless & networks. Just under "Airplane Mode" is a selection that says "4G." When off it should say "Turn on" in blue just under it. When you check this button you should get a green checkmark and if you are in a 4G area it will say "connected". If not in a 4G area it should say "Disconnected" in blue. If you HAVE the 4G problem, it will say "Unknown."
