530 unsuccessful pair with phone

hi got my garmin 530 2 days ago, but it just gives me only frustrations

i cant get it to pair with my samsung s9 or girlfriends iphone se

updated it to the latest 3.41 beta version aswell, but without success 

the gps aswell loses connection every few seconds and even standing still the device counts meters and gives random speed numbers

i can see the device via bluetooth and sometimes it gives me a key for completion, but the app tells me that the pairing was unsuccessful and the device is still in searching mode

did i get a faulty device and should i send it back? or am i doing something wrong
