Onda has posted the above video on their Weibo of the v919 3G Core M’s Windows 10 + Android 5.0 dual boot switching abilities. It’s a true dual boot bios and switching system. Not a emulated Android ROM like the Cube one or Teclast X1 4G Pro. It will be the first true dual boot Core M device out.
Mine ordered v919 3G Core M for review hasn’t shipped yet, seems there is a delay as I was told it comes only with Windows 10 in Chinese. Newer models it seems will ship with dual boot, I’m not sure if Onda has release a dual boot bios, Rom and Image yet as I can’t find anything on the Onda forum.
