512MB was a huge flash drive now it's not enough ram. Turns out Spotify can't open-source Car Thing because it's a potato https://www.androidauthority.com/spotify-car-thing-open-source-3449487/

I just got a new D4v2 quad 20W UV and have just cycled through the modes a few times and noticed the LEDs look burned out. I could understand if I used it on the turbo mode for a while but for just a few minutes used I'm a bit concerned and confused. Did I do something to damage it?
