Huawei Mate S Marshmallow beta program

If you want to enjoy Marshmallow beta program, write your IMEI and your current firmware to matesbetatest@huawei.com.

I just use Android 6.0 in Huawei Mate 7 and it is perfect :)

IF you want to install OTA in February, you first need to be running B145 firmware, you can download it here - http://huaweifirmware.com/huawei-mate-s
