Having come from owning a photolab I am fully aware of issues about image resolution.
As a generalisation, images above
100 dpi will print acceptable results, with 300 dpi being the ideal.
Phone cameras can be lower resolution, and cropping will reduce pixel count further.
Images on facebook or sent by picture message are typically resampled down in resolution, and many images come from google images and are small too.
If you work to 100 dpi then simple maths will tell you how large you can realistically print it, and no amount of Photoshop will really improve.
Fractal image manipulation can improve the visual appearance, s-pline of focus magic can have their place.
Regarding the red lines I would suggest looking at the colour working space you are using, rgb or cmyk? We stick with sRGB over adobeRGB and have encountered these types of issue with conversions.
