Hi There,
Same issue here on mi8; I always put my phone on air plane mode at night to avoid being disturbed.
In the morning, the Bluetooth is not working anymore and I have to restart my phone to get it back.
I have not tried for the hot spot share connexion and I definitely will, but wouldn't that be a restriction from your operator ?
I recall sharing my connexion on my mi8 with my laptop without any prob...In China, operator do not restrict this, in France, they definitely do when you are on a pre-paid plan.
Other than that, Great job from the team, I can see many bugs fix as well, so thumbs up!
