We thought that the much anticipated split-screen feature would come along MIUI 9 (in August), but Xiaomi wanted to it to be a surprise release. Yes, you heard it right. The split-screen is here and Xiaomi Mi 6 is the first phone to feature this function.
As expected, the split-screen function has been introduced to MIUI’s latest developer version “MIUI 8 7.6.26” of Xiaomi Mi 6. Along with the addition of the highlighted feature, the UI has also undergone some noticeable changes as well.
While testing, the split-screen function is smooth and stable. We have not seen any bugs in it so far. Maybe because of the Mi 6 high-end hardware, opening multi-windows and some background apps didn’t turn the phone slow at all. But the question remains that whether the same smoothness will be maintained in the low-end Xiaomi smartphones such as Redmi Note 3, Redmi 3, Redmi 4, and more?
However, as usual, we found some issues in the UI as in each developer version updates. This time the WeChat fingerprint payment function failed for unknown reasons. Hope the developers fix them as soon as possible.
Let us make this clear that from now, we won’t have to wait for MIUI 9 major update to use the split-screen function. It appears that the MIUI developers intend for a surprise release in the developer version update for other Xiaomi smartphones as well. If you are among the Mi 6 users, you can test the function by installing MIUI 8 7.6.26 developer version for Mi 6.
