After Vivo X5 pro and TCL 3S this two devices comes with iris sensor this year. This year many Big branded flagship devices launched with fingerprint sensor but they lack of the iris sensor. According to @evleaks The Microsoft Cityman feature an iris scanner.
This report came from the leakster Evan Blass twitter account aka @evleaks and confirming that Microsoft Cityman skips fingerprint reader and employed the iris scanner for biometric authentication.
So from the report it is clear that Microsoft Cityman will be a Microsoft Lumia 940XL and Microsoft Talkman believed to be a Microsoft Lumia 940.
The other specs of the Microsoft Lumia 940 and Microsoft Lumia 940 XL already leaked but not all the features got so far. If the rumors, news is true, then it might be a game changing device by Microsoft so far.
