Huawei Mate 2 - 6.1" Unlocked GSM 4G LTE

What sub-model of this Ascend Mate 2 phone is this?

I was looking at this as a car tablet or an e-reader. Passed because there is no way of knowing if Lollipop will be compatible with this specific model. Apparently, they rev’ed the H/W during production and they are vastly different. Same rough specs, different. The battery “(typical)” designation shows that. You don’t know what you are getting.
