Woke up on Monday and my Pixel 6 Pro wasnt quite fitting in the case while i was checking news while having coffee on the morning. Pushed it in and it didnt seem to fit right. Took the case off to find it had turned itself into a spicy pillow and was splitting along the side. Was 1 month inside warranty, messaged support who told me it was wear and tear initially. I made it quite clear i wasnt accepting that and there wasnt even any way that internal adhesive failing would be wear and tear, never mind battery expansion. They agreed to replace it with a refurb as a goodwill gesture, how very nice of them. I upgraded the same day to a S23 Ultra and have sold the refurb to a reseller.
It seems to be hit or miss. My wife and I have both had Nexus 6p, Pixel OG XL, Pixel 3a, and are currently using release day Pixel 6s. We haven't had any issues with ours.
Dang my wife just gave up her pixel 2. It was lasting forever it actually still works fine just the battery doesn't last very long. She's got a pixel 7 now. The guy at Koodo had never even seen a pixel 2 lol.
