I just moved from the XL to the X3 yesterday. I was going to do it, no matter what. here's my first thoughts in comparison
-XL is faster but the x3 is smoother. I expect firmware tweeks will increase the speed and flow....just like the XL
-after 24 hours, the batter does not exhibit the normal first week battery breakin. So far, no unusual rundown. Has Beast potential
-Continumm is what you make of it.
-Sound was excellent
-Call quality is excellent
-Connectivity, as in signal, is better for me than the XL
-Camera is broken...but everyone knew that
-Look, feel, touch...more iPhone-ish that Windows Phone ish
-Fingerprint reader works fine on AU. I'm disappointed in the reader in that I expected to be able to link other login functions to it, like Android and IOS. Maybe I'm missing it.
Overall, I like it. I'll like it more after the firmware update. Camera and speed are 2 areas of improvement. Daniel mentioned how to prevent the camera from blowing up...that works, most of the time.
Would I buy it again...yeah
Regarding statements around the Plastic grill and 'having lots of problems'...the grill is fine. It is what it is. People that say the grill is a deal breaker are only fooling themselves. Its no better or worse than any other phone. You like, you don't like, fine, whatever. As far as lots of problems...well...I see few. My treasure might be your nightmare, The Note 7 blew up...the iPhone 7 wouldn't work on T-Mobile. Lets compare.....
So far...I like....
