Install Pixel experience on your old android phones to get all the features (except hardware) of a Pixel phone. Android 12 gives you unlimited photos and video storage in original quality in google photos.
I recently installed pixel experience on my Oneplus 5T (6 year old device). I'm able to experience all the features of a Pixel device including unlimited free storage on google photos in original quality. Google Camera, live caption and a lot more.
