So you find the Note 4 to be poor vs. your G3?
This is my first Spark device so it is hard for me to compare. Band 26 will naturally get better reception than 25, but I haven't been blown away by it. Maybe it is from lack of optimization. I know that signal levels are reported differently on voice bands vs. LTE bands, but voice is stronger for me.
I do think after the Lollipop update Band 41 is a little better, but maybe I'm wrong.
There are still times when I drop to 3G and it takes too long to go back into LTE.
