Corrosion and Pitting

My Video doorbell has corrosion and pitting on the metal covering that wraps around the front button. Looks like it's aluminum with a thin copper veneer. The copper is flaking off and the aluminum underneath pitting. It's around ALL the edges and even around the circular edges of the button. Is this a known defect and something Ring is addressing? The doorbell was on the back of my house and not exposed to salts or any sort of chemicals. Just sunlight. I have attached a picture. Disappointing seeing how much I paid for this.
