mate 9 is nice, but at my opinion, i think my LG5 is better.
Pros for G5:
* changeable battery
* wide angel second cam
* higher screen resolution
* FM Radio
* better fingerprint sensor
* better camera pictures
Pros for Mate 9:
* bigger battery
* bigger screen size
But after i have given my G5 to my wife, i have to live with it (until i’ve found a better device).
I dispute the points of a better fingerprint sensor, camera and exchangeable battery in the G5 pros. With a screwdriver you can replace the Mate's battery and its fingerprint sensor, I doubt it's possible to find a faster one out there. Camera quality? Highly subjective!
