No sir, not what is going on. If I get to an area with crappy signal it drops to 3G... yes... but once I'm back on 4G coverage, it doesn't switch back.... stays 3G UNLESS I turn off and on the phone, and it locks in LTE and 4G works like a charm until of course I run on a crappy coverage area again and it drops from LTE to CDMA (3G).The device is a scanner it will pick up on the strongest signal first . So if 4g is the best that's the first . When it scans and notice that 4g is crapy it will use 3g
