>>3399730honestly, after 4 years of shooting mobile photography (w/ shit phones and flagship phones), i can say that you need to get your post-processing skills up first
google how to turn RAW shooting option on in your phone and learn how to process RAW photos
also focus on composition/color theory/holding your hand without shaking (so that the photos get maximum sharp) and them everything will be ok
software-wise: snapseed for (almost) everything, learn how to use curves (that's a _must_);
lightroom for HSL tool;
vsco for occasional filter (rarely, also it doesn't support raw on android afaik)
