Advice appreciated thanks
I have just performed 2 out of 3 video tests I plan to do with my Galaxy S4 to address this very issue. All are on the same device. Video #1 is LTE test and, just a few minutes after, Video #2 is testing XLTE.
I have yet to find a "Application" that shows properly Band 4 or Band 13 so we can tell, but the Service Menu DOES TELL! You just have to unlock it. Also, I had previously thought that XLTE was using both bands to double it's bandwidth. This of course is NOT the case. The device switches over entirely from one band to the other. The Service Menu shows that Band 4 mode is utilizing 20Mhz as apposed the original 10Mhz on LTE Band 13. Double the Mhz bandwidth, that explains it!
