According to the list, Huawei Ascend Mate 7 will first get the Android 5.0 Lollipop update starting in May followed by Honor 6, Honor 6 Plus, Ascend P7 and Ascend Mate 2 starting in June-July. While few variants of the Honor 4X may also start getting the update in June-July, some according to the plan will get updated in September along with the last year's mid-range Ascend G7.
It is not known if there will be an update to the company's own Emotion UI (EMUI) as well, but considering the EMUI page lists the update - we might see a Lollipop update wrapped in the new version EMUI.
The company recently released the Honor 6 Plus and Honor 4X smartphones in India with price tag of Rs. 26,499 and Rs. 10,499 respectively. Huawei's Honor 6 Plus was initially unveiled in December, whereas the Honor 4X was unveiled in September in China. Both smartphones run Emotion UI 3.0 based on Android 4.4 KitKat.
