Xiaomi will officially release its next MIUI update, that is MIUI 9, on July 26th alongside the launch of a new smartphone namely Mi 5X. However, the Chinese manufacturer has already started beta test of MIUI 9 for Mi 6 and Redmi Note 4X and these will be the lucky devices to first receive the stable build of MIUI 9 as well.
After Mi 6 and Redmi Note 4X, the next batch of devices which are included in the list for MIUI 9 update are Mi 5, Mi Mix and Mi Note 2. As per a Weibo leak, Xiaomi’s flagship devices Mi 5 and Mi Mix as well as Mi Note 2 have been included in the second batch list which will be receiving the latest MIUI update.
Past report had suggested that Xiaomi Mi 5s, Mi 5s Plus, Redmi 4, Mi Max 2, and Mi 4 will also find place in the second batch, although the latest Weibo leak does not make a mention of these devices.
Other Xiaomi devices too will get the update at a later point of time which, for now, is not clear. You can check out the complete list here.
