Redmi Note 5, one of the most successful Xiaomi smartphones in India, has lately been hurting for MIUI updates. Not anymore, though, as Xiaomi is just now releasing the MIUI build number 10.2.1. Update fixes a large number of issues with an earlier build 10.0.4. The full list of fixes is as follows:
