I just noticed that my Google Nest Hello is also peeling and found this previous thread. It looks like it's closed so I'm not able to reply to existing comments.
Similar to another user when I first say this I thought I didn't take all the film off the device. However that is not the case.
My Nest Hello is under a covered porch so it should not be peeling. Similar to the other results I would like to request a replacement. I have lots of Google Home devices (Hellos, Thermostats, Secure, Cameras, Hub Max, etc) and would like my system to continue operating as intended.
