HTC is committed to delivering a high quality product and great experience for all our customers. There have been a few, isolated reports of this issue. The finish on the One S was laboratory tested as being at a hardness similar to ceramic. While that’s hard, it doesn’t mean it’s impossible to damage. Regardless, HTC takes quality very seriously and are providing all customers with an immediate fix and we are implementing some small changes to ensure customers do not experience this issue in the future.
Basically HTC One S owners who are currently experiencing chipping on their devices will be eligible for a swap by going back to the store that you have bought it from, assuming that it is still within 30 days of purchase. However if you stumble across this news much later and you’re well past the 30 day limit, HTC will still fix your device under its standard warranty terms. Good on them for responding so promptly.
