I have my phone taking pictures at the highest resolution, but if the object or person I'm shooting is more than a few feet away, the photo is pixelated when blown up to fill my screen. This is especially problematic when I'm taking pictures with the flash in a darker room.

Is there a setting on my camera that will ensure my pictures don't end up pixelated. My friend has a Canon camera that's at least six years old, and that old school gadget can take photos which can be blown up many times its size and it still doesn't look pixelated.

Any advice?
