His phone won't keep a signal in 4g. It will dial and then will never actually say connected and then it says no connection or something like that. My Max my sons Max and the s3 have solid connections. His 4g goes away and shows an x inside where the bars are. 3g works fine. I am kinds bummed because the phone looks like it would be a great phone. We are probably gonna go ahead and get the S3 instead. I am to concerned with the signal to chance it again. Thanks for your help guys.
There is a way to keep it just 3g.
Go to settings, right under Data Usage there's a more option, then go into mobile networks, and under network mode there are two options;Lte/cdma and cdma. Cdma keeps it in 3g and of course lte/cdma means that it'll search for 4g and when it doesn't find 4g it'll search for 3g instead.
