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.
Using the sensor behind the screen turns on a surprisingly bright circle of the screen behind your finger, even with the rest of the screen dimmed (say, because you're in bed with the lights out) it's the same brightness, probably just 100%. Presumably it helps the sensor work better. Move your finger a bit too much and that brightness hits your eyes. Which can be uncomfortable at the surprising level of brightness.
