A few issues...bluetooth, lightflow, always on...

[TJohnsonmp01]

I LOVE My Note 7 but I have ran into a few issues the past few days:

Bluetooth:
It list all my devices (car, headphones, watch). But when I press them to connect it literally does nothing. I have unpaired, repaired etc with no such luck. In my car it shows my phone but won't connect either.

LIghtFlow:
I love this app. It works for all other notifications I have set except for text. I use stock sms and lightflow does NOT show the light when I receive a text.

Always On Display:
Keyword ALWAYS..the past few days it either completely goes away or dims. AND this is with alot of battery life left so not sure why.

Notification Sounds:
I have a couple of group chats for work and with my besties. I have set a special ringtone for each group. Well it doesn't work. Or for work it works for 1 person if they text me but not if they text as a group. Any suggestions?

Favorites in Contacts:
I really miss having this! It was a GREAT feature...not sure why they would take it away.

Thanks ahead of time for any ideas/suggestions!
