Huawei Honor 6 is now getting the Android 5.1.1 Lollipop, enhanced with the new EMUI 3.1 launcher. The first country to get the new firmware is India, but oddly the update is now available via the OTA service just yet.
Huawei has uploaded the ROM on the official Huawei India website, so you can download it from there and update it manually. Just few people reported for OTA notifications. The file is 1.3GB big, so in case you'll do the update manually, you should free at least 3GB on your phone.
There is no official changelog for the new firmware, but it will upgrade your KitKat up to the latest Lollipop and bring some traces of Material design, lots of under-the-hood optimizations, better security and switch to ART runtime for better performance.
Huawei Honor 4C and Honor 4X already got the update - in case you've missed the news you can found the ROMs over the source link. Now it's turn for the Honor 6. Other markets should be getting the update very soon and hopefully the OTA release is just around the corner, too.
