I have trouble connecting with Mi Band 3 fitness tracker with my OnePlus 6T. I have been using band 3 from the past 6 months and it was working fine. One day, I noticed my band 3 disconnected from phone even though Bluetooth was On. I quickly restarted phone and it worked. But from yesterday, it was completely disconnected from phone and it's not connecting again. I tried following methods, but got no luck.
