I've sent feedback also request a new Firmware. Specifically fixing the 4 issues:
FIRMWARE PARAMETER ISSUES:
1) Root Device Category incorrectly set (Computer to Computer.Portable) - causes UWP Apps to display inconsistently.
2) 9 "Speech" languages installed by default on the X150Q (US) Version W10M update... Shouldn't have that many in the N.America ROM. ROM incorrectly set up.
FIRMWARE DRIVERS ISSUES:
1) Screen Dimmability "flickers", is not "smooth" like other W10M devices. Possibility need W10M Driver Update for Screen Controller.
2) Camera AutoFocus sporadic, not like other W10M devices. Can't autofocus, unless user taps screen location. Possible need W10M camera driver update.
X) Maybe updated WIFI Driver to display WIFI "In/Out" Arrows like other W10M Devices??
