Huawei appears to be working towards releasing Android 6.0 Marshmallow update to its devices, as it has started beta testing the firmware for its device, P8lite.

The company is allowing 100 participants each from single-sim and dual-sim variants of P8lite to beta-test Android 6.0 Marshmallow to pave the way for a public release at a later stage, according to the Huawei Romania Facebook page. 

The Chinese company hasn't announced the firmware's update schedule for its devices, but the P8lite should be one of the first. Android Authority has reported, quoting sources from Huawei, that the upcoming US-bound Honor 5X will come with Android 5.1 Lollipop, but get the Android 6.0 Marshmallow OTA (over-the-air) update on the day of its release, ie, 31 January, along with the latest build of EMUI4. 

So, it appears the Honor 5X will be Huawei's first device to get the Android 6.0 Marshmallow update.

Huawei has announced it will roll out the Android 6.0 Marshmallow update to a dozen of its devices: Huawei Mate 7, Huawei Honor 6, Huawei Honor 4X, Huawei Honor 4C, Huawei Ascend G7, Huawei Ascend P8, Huawei Ascend P8 Max, Huawei Honor 6 Plus, Huawei Honor 7, Huawei Honor 7i, Huawei Mate S, Huawei MediaPad X2 and Huawei Ascend G8.
