Xiaomi Mi9 has recently received a new MIUI update for the global European variant. This update brings a few bug fixes and fingerprint sensor improvements. Notifications are also fixed. I have tested it personally and fingerprint works better than before even with a screen protector installed. Some users reported on the XDA forum that battery life dropped after the update but for me, it came back to normal after 1st recharge. The method I used is a manual update through TWRP. This post is especially for those who have rooted their phone and now want to update phones without losing data. This update is only applicable to the PFAEUXM build number.
