Here's one of the improvements Google might want to look into for the Pixel Watch 2: better glue. Android Police spotted a few reports of the back panels of some Pixel Watches just falling off. A few posts on the PixelWatch subreddit have photos of this phenomenon; several commenters say it happened to them, too.

This certainly seems like something Google should cover under warranty, and with the device being less than a year old, everyone should be under warranty. You also have a strong argument if you contact Google support about a device that has fallen apart. The scary thing is this will also compromise the device's water resistance, and we doubt Google is covering every instance of water damage. Most reports indicate Google is taking care of the problem, but a few users were initially threatened with a $300 repair fee, which was later waived.
