Xiaomi Mi 9 has recently received a new MIUI update for the global variant. This update brings a few bug fixes and fingerprint sensor improvements. I have tested it and the fingerprint works faster than before even with a screen protector installed. Some users reported on the XDA forum that battery life dropped after the update but i did not notice any significant change in battery. Maybe because I used 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.
