Arghya139 , via OnePlus 7 , Oct 17, 2019 : I am using one plus 7 the 6 gb ram edition Bluetooth is Plantronics Explorer 50 Os is 9.5.8 AA version. Problem is that even after pairing everytime I turn on Bluetooth, it will not automatically connect, I have to go to Bluetooth option manually and click on Bluetooth name to connect. I gave Samsung, Honor And Redmi devices in my family and none have this problem with same Bluetooth unit. I tried with 1+ support team, they first asked to clear cache and some other steps, when it didn't get solved they simply said we do not provide any support for third party Bluetooth device u have to buy one plus Bluetooth. Can anybody help please?
