My friends regularly have to have their Pixels replaced/retired due to hardware failures around the 2 year mark. The 7 years of support is nice, but these phones don't last anywhere near that long.
I had a Pixel 2 XL that was replaced this year not because it was broken, well the screen was bit that's hardly the phones fault, but because my carrier had an offer on a Pixel 7 that was too good to be true. The Pixel 2 is still working so, even if there are no more OS updates anymore.
4a 5G was my favourite phone since Nokia N9. Fast and lightweight, great photos, fingerprint reader in the back.
I switched to Pixel 7 so that my partner can get the 4a 5G to replace their aging device. But this 7 is clearly heavier and while a good device, I just don't like it quite as much.
