Xiaomi on its MIUI official forum just announced the release of MIUI 6 global beta build for its Redmi 1S users.
This is a promising build and definitely a welcome upgrade to lots of Redmi 1S users. However, it’s still on top of Android Kitkat and seems to disappoint some users who are hoping for the Lollipop upgrade, instead.
Regular updates will follow, roughly every 2 weeks in response to whatever the beta testers will come up with their user experience and reports on bug-related results.
As of now, the current build has at least two known issues, specifically with the Redmi 1S having some occasional hiccups connecting to a network after restarting, and its battery dropping fast also after occasional rebooting.
