Here's an example of a phone photo I took recently. I think it looks good after some editing. Your phone has to have raw support if you want more wiggle room for editing. Stock camera is going to be the best, most of the time. I am still a beginner so probably best to invest bare minimum in a decent beginner camera. But for android I mostly use Lightroom Mobile(better use LRC on pc), Snapseed - for editing. Stock Camera for shooting, though there're mods for GCAM but they look awful imo
