Issues with radio

#1
Hello,
So I've been struggling with my radio on my 17 Corolla. It will sometimes kick my phone off the Bluetooth, or do this strange thing where it will display I'm calling myself, but my phone isn't dialing anyone, and the music comes out extremely distorted as if I was on a phone call.
When it does work, there is a 3-5 second delay on audio when I skip to the next song using the phone or steering wheel controls and it starts the song a few seconds in.
I took it to the dealership and they couldn't recreate, and they did a software update. It didn't last a day before it resumed. It's doing this with 3 different Android phone. A Motorola, a pixel and a Samsung S8.
I'm absolutely stumped and the dealership wouldn't help or try to get a new one
Any suggestions?
