I have a Galaxy A50 phone for my personal cell phone and an iPhone for my work phone. I bought a Bluetooth device that will let me answer calls handsfree for both phones and that works fine. BUT...the device is naming my work phone "Phone 1" and it wants to make outgoing calls through that phone. I want outgoing calls to go on Phone 2 which is the Galaxy A50. I called the maker of the device, Nulaxy, to ask how to change this and they said I cannot. I contacted Samsung and they said I could start by going into the Bluetooth App and deleting all the Data in the Storage system. The warning tells me I will permanently delete files and other things. Are those things that may cause a problem if I delete them? Does anyone have an answer on how to make The Nulaxy refer to the A50 as Phone 1? I have tried Forget This Device on the iPhone and I tried Unpair on the A50 and then repairing, etc., but that did not work. Thank you.
