I won't tell you not to use a mobile phone camera because they are convenient but they have limitations. Understand those limitations and make adjustments before and after the shoot. For best quality, use the highest MP sensor, resolution and lenses you can.

This does not mean that phone pictures won't be accepted, but only that the conditions to take pictures need to be optimal.
