BT pairing F2 watch with samsung note 3 how to??

[AC Question]

Hi. Abit of a novice here so laymen terms are good! Anyone know how to pair BT a f2 smart watch with samsung note 3 using mediatek apk? Have downloaded v1.1.1 mediatek app & connected as per instructions. Music connects & text notifications but everything else says "not connected" or "can't find smart device".?? Any help and information greatly appreciated, thanks
