how you shoot is going to depend a lot on what you are taking photos of, like for shooting photos in a city i recommend the built in google preset Ollie.
alternatively, editing using snapseed and utilising one of the looks in that app. and just play with the different filters and sliders see what looks nice for you. snapseed also offers raw photo editing if you make use of the ‘expert’ mode in your nothing phone camera app.
if you are taking photos of your friends and family I would recommend just shooting with nothing default settings, and definitely make use of the glyph fill light when you are close enough, it is a much better light for photos than any phone flash to date.
if you want to go the paid route, lightroom mobile has a built in pro camera and edits jpegs for free, but raw photo editing will cost you a monthly subscription.
hope this helps! 💙
