The build numbers of the software updates are R16NW.N950USQU4CRF3 for the Note8, NRD90M.N920VVRS3CRF1 for the Note5 and NRD90M.G928VVRS3CRF1 for the S6 edge+.
But while the Note5 and the S6 edge+ are getting just the security enhancements, the Note8 users will be happy to hear that the OTA update adds the so-called Auto On feature for WiFi calling. It allows you to receive calls over your home WiFi network, for example, when cellular network isn't available.
I just got June security patch for my Honor 9 on July 1 st. So I guess this is the typical update time then?
