When I say in the comments here that the SoCs being used could easily support more than the new usual 6 years of updates, this 8 years of updates is the proof that I was right. How I know? Because I use a phone from 2019 with a custom ROM and it still "flies" (=is super fast for what I do) (obviously for gaming, the SoC may not be enough, but what is the % of people that game + where the SoC gaming performance wouldn't be enough? Not very high.). When I read 8 years, I though that a Cortex-A720 / A520 setup would be a good minimum for the 8 years to make sense, and this does indeed have the required cores / SoC. Now we need this 8 years of support for smartphones. I say 8, because at some point battery life may become too decreased, but it battery was easily replaceable, even 10 years of support would make sense.

DO you know any keyboard that works\designed for this tablet?

Can you please fix this article. Tab Active 5 Pro does have hot swap. However tablet turns off the screen when any of batteries are removed. But is not shutting down whole Tablet.

The website explicitly mentions hotswappable batteries, maybe it was a bug? samsung.com/us/business/mobile/tablets/galaxy-tab-active/explore/

Removable batteries keep you moving in the field without powering down your devices.²

8 years of updates? Are they serious? Great news if they really commit that.

And yes it does have 3.5mm audio jack to my surprise...

You didn't write about the ports of the tablet,
Does it has an 3.5mm headphone jack ?
