Note 3 having issues switching back to 4g lte in capable areas.

[Jorge Lavayen]

It seems like when my note 3 is in areas of low 4g lte signal, it automatically switches to 4g, which is ok I suppose, but when I get back to a high range of 4g lte area, it has a hard time switching back to 4g lte. This isn't the first note that does it, as I warrantied the other note 3 I had.

Is it software? Or hardware?
