The last major phone teardown that made the news was Samsung's poorly designed Galaxy Fold. It didn't last very long, either, since Samsung contacted iFixit and asked them to remove it, stirring up even more bad press.
The good news for Google is that their Pixel 3a looks (relatively) easy to take apart and repair, so there's not much to take away from the positive press that the phone is enjoying right now.
iFixit's teardown included the usual process of disassembling everything in the phone to check out what's inside of it and how easy those components will be to replace. They found that pretty much everything was modular, which is good, and the phone just uses standard T3 screws instead of anything weird or proprietary. The battery is also easily removed and easily repaired.
The not-so-good portions of the teardown found that the display is thin and not well supported, and there are quite a few long and thin ribbon cables connecting everything on the inside of the phone. Those cables could be easily to accidentally tear, and then you've got a whole other repair on your hands.
Overall iFixit rated the Pixel 3a a 6/10 on the repairability score, with 10 being the easiest. It could be better, but it seems rare to ever see repairable phones anymore, so this one's not so bad.
