>>4348750I think everyone does this, it's nice to have sharp pictures but overdoing it causes this staticky grain / noise / white hilights that look ugly when viewed at 100%
I would suggest that you make sure you're at 100% when you're adding sharpening, and more that pictures that have come from a phone really don't need any extra sharpening at all...
If you like the unsharp mask effect figure out how to use it for local contrast, that always makes things look nice if used sparingly
