Meizu Pro 5: Wifi channels 12-13 should be enabled for Europe

[Michael]

Meizu Pro 5 doesn't find the SSIDs of 2.4 GHz 802.11g/n networks at channel 12-13.

Steps:
Set your 802.11g/n wifi AP manually to channel 12 or 13
Switch Meizu Pro 5 wifi off->on

Expected:
Your AP should show up in the list (most of the world)

Actually:
Your AP should doesn't show up in the list (North America)

As the model is sold world wide there should be at least a location/country based enabling of those upper channels. Or two different NA/ROW (rest of world) images.

Is this a firmware issue which can be fixed?
