I bought a Samsung phone back in like 2014, and shortly after bought smartwatch to pair with it. A year later, Samsung released an update that removed the pairing functionality so my smartwatch could no longer pair. They did this in conjunction with releasing their own smartwatch and some proprietary pairing protocol.

I'm not a fan of vendor lock in, but their decision to retroactively remove functionality that I was depending on led me to never buy another Samsung product since.
