I’m absolutely still using teamspeak. Nice and light, and it let’s us run a soundboard plugin that let’s you have unlimited length audio clips. I just wish they’d update the plugin to support the 64-bit version.

Certain Samsung’s have Hiya integration for this kind of thing. In the dialler settings there might be an option for “Caller ID and Spam Protection”.

Make sure there’s no lint and dust compacted in the bottom of the port if you haven’t already. It isn’t always entirely obvious but it can affect both lightning and USB-C and you can usually get it out with some careful use of a sewing needle.
