Personally I wouldn't touch a phone with an Exynos processor again, even ones of equal specs to a Snapdragon always run worse and have worse battery life, looking at that one it doesn't match the Snapdragon.Very tempted but not having spent more than £200 on a phone before I am a tad nervous. The fact that the 4a is not too big, has an oled screen & the camera is supposed to be so good certainly appeals. Samsung m31 has oled screen, excellent battery but it is a lot bigger and camera is decent apparently but not pixel quality. Decisions??
Plus with the Pixel you get 3 years of fast updates, the Samsung they will be a lot slower as always.
Yes it's £319 but the phone will last you longer than the £200 Samsung which I imagine will be stuttering from new with that chipset. It's cheaper for a reason. Depends on your expectations.
