That’s a very nice phone camera! That, or I’ve an even poorer phone camera than I thought (on the grounds of having a full-body camera). You can probably find free apps for your phone that do simple RAW edits, but I can’t offer any advice. Dedicated cameras tend to come with software of varying quality (Canon is quite good!).
I quite enjoy doing light post-processing on my photos, but yes, it involves setting time aside for it, and the discipline not to spend more time on a photo than it is worth.
