My Xiaomi did an update Monday and since then the weirdest thing started happening. I've been using it as a hotspot in my car for a while but since Monday when I try to use it where I work I can't turn it on. Keeps saying error. Yet as soon as I get home it works fine again. I'm stumped! Tried all the usual things, airplane mode, turn phone on then off, WiFi on off. Not a major issue but it just means I can't stream stuff to my car screen anymore, and it could have been used as a backup of android auto stopped working for me. Anyone else having any issues.
