I don't know why the Pixel 3a XL has the 3.5mm headphone jack. Yes, it's traditional still and there's no change in it as such yet. But still, going a step further would have looked cool :cool: :cool:


I've always read that something like 48MP+16MP+8MP as against a smaller 12.2MP sensor does not necessarily mean the bigger one dishing out better images. How about in this case?
