- The fridge had both front and back cameras
- It had a microphone
- It could play music, which maybe was important if you considered it for a glorified kitchen tablet
- It could install regular android apps
- It could sync photos and notes
- It was compatible with the Uber app, so I have to assume you could actually have payment info in there
I have never bought a nice fridge and I will go out of my way to avoid pointless smart, so it really came as a surprise to me, but the situation seems posible and probably will happen to someone at some point
The rest are all potentially useful as well, but more important than any of these are security and longevity - a flagship phone from Samsung gets something like 5 years of updates if I recall right, and those updates are prioritized according to how premium the phone is - how far down the list are fridges? I would definitely want my fridge to last longer than 5 years and NOT be a security risk in my network.
Apparently fridges get at a minimum 2 years of updates with Samsung, but after that no updates are guaranteed
