Hi i had problem with my speedy.
Sudenly it disconect and stop talking to my iphone.
Turning it off and on not helped.
Forgeting device in blutooth manager also.
After long pressing blutooth button, 5 leds blinked once and still no connection.

But there is undocumented reset button ! 😊
On the back side little right , you will find tiny hole. Use needle for pressing it.
