You find reviews and look at the camera notes and examples.
Here we don't look at the Huawei due to spyware beyond what you get in a Google phone. Google's phone is also more likely to be kept current on the OS for longer.
I am looking to buy a smartphone to replace my now useless iPod Touch but I want to buy one with a great camera. My budget is a bit limited so can't go latest generations. I was between the Pixel 1st generation and Huawei P20 lite. What do you reckon is best? Needs to be able to play music (but all of them do, don't they?!)
THANKS!
