I have seen people being displeased with 10S made for this when they can't even change the default browser being Edge. I'm sure this teardown will push them even more further away. I also bet a drop test proves not only that it could permanently ruin this, but that any inflicted damage could mean that the entire device needs to be replaced. I may have been !#^&@@ about Microsoft since Windows 8, but this takes it to a new low.
It's not a phone in general of there is no front face speaker on top like actual phones have, plus that you can't call on it without continuity because there's no phone app.
