You could purchase a silicone case--like we and other customers have done--to cover up the peeling. It's not a real solution. But if your Google Nest Hello Doorbell is more than a year old, it's not likely Google Nest will replace it.
With your post, there are now 280 threads about "peeling" Google Nest Hello Doorbells in this forum and 27 threads about "delaminating" Google Nest Hello Doorbells. One of our Nest Hello doorbells--20 months old--is peeling. That Nest Hello and another one of ours also won't ring the internal chime anymore due to a failing internal battery (another defect with hundreds of posts here in this forum). It certainly seems both are clearly known defects. Yet in spite of all these reports Google Nest says they "cannot" replace them if they are more than one year old. "Cannot"?? It seems rather they will not do anything.
In previous posts, I have suggested that customers with Nest Hello doorbells that are peeling--or failing to chime due to a failing internal battery--be given a discount on a new, RE-DESIGNED Google Nest Hello Doorbell (NOT the new battery doorbell) that has a user-replaceable internal battery obtainable from Google Nest and that corrects the susceptibility to peeling. So far, no one from Google Nest has responded to this suggestion.
