I hate Bluetooth.
I hate how audio is controlled on our modern devices.
Case in point: I'm working in my shop. I have my Spotify playlist up on my phone, and am connected via Bluetooth to my speaker, so I have music playing. If a call comes in, it projects over the Bluetooth speaker, which is in no way a useful or valuable place to have phone calls sent.
Or I take a break for a minute to sit down and have some water, and play a game on my phone. And now that game is bring projected over the sound of the music through the Bluetooth speaker.
Why can't I just have music sent to the Bluetooth speaker, and all other audio routed through my phone's built-in speaker?
What about my car?
I connect to my car's entertainment system via Bluetooth, and I listen to podcasts and music while driving. But every single notification that comes in pads my audio 25%, so I miss what the podcasters are saying. If I get multiple notifications in a row, I can miss a LOT of information.
Or maybe I want to use my AirPods, instead of the car's stereo system... but nope. Trying to get the car to release its Bluetooth lock on my iPhone is impossible to do when driving. And even when I do get the audio re-routed to my AirPods, if a call comes in, my phone disconnects from my AirPods, reconnects to the car stereo, and plays the call over the stereo system!
"Fixing" these problems is actually two different solutions to two different problems; one fix is possible, the other impossible.
The first option is to have some sort of built-in mixer into the OS, that allows me to specifically route specific app outputs to different places. So, send Spotify output to the Bluetooth connected device (speaker in the shop, or car stereo, for example) and send all other audio through the phone's built-in speaker.
The second option is to have multiple outputs available via Bluetooth. So I can send Spotify to my job site boombox, and phone to my AirPods. This can't happen, because Bluetooth cannot address more than one destination; there can be only one Bluetooth device connected at a time.
Most of the time now, I just drive with no audio at all. It's just less annoying to have to deal with these asinine design flaws in "modern" technology products.
(But hey ... at least I'm not trying to avoid conscription gangs and looking at leaving my homeland for good and becoming an exile from my own country. (Yet.)
