[Miscellaneous Android Development] ViAlexSt:
I don't care what translates the Google translator. Build.prop tells a different story:

And the content of the firmware for China.

Although I understood the thing - we're talking about slightly different versions:

V919 AIR CH 中性固件（适合014版本以上BIOS）-20160729.zip

V919 AIR CH 双系统android固件（V7版本）-20160706.zip

They are the same framework and system apks, different only in the region.

I take the firmware from another source. The Chinese have these Baidu-sources - as in Brazil monkeys.
