Problem with Bluetooth

First of all, thanks for the wonderful phone and
I have two problems with the Bluetooth.

First.
When connected with Bluetooth Handsfree with open the screen, everything is fine.
When the phone is asleep (restricted screen), then every 1 or 2 minutes the Bluetooth Handsfree says
"the phone no connected/ the phone connected"
and is repeated until you open the screen.
Why this happens? and how they are solved?

Αnd second.
If you open first the Bluetooth Handsfree and opens after the mobile Bluetooth
then not connected and can not.
Thanks.

Try it another bluetooth in Apollo and do the same, when the screen is closed every 1-2 minutes tells "connected".
My own bluetooth try it in another phone Lenovo and work smoothly.
How can we fix this?
Thanks.
