How to Doodle a Mobile Phone
Begin by doodling an upright rectangle in the middle of your page.
Now, doodle a smaller rectangle inside the larger rectangle. Pay particular attention to keep the spacing between all four sides of both rectangles even. Use additional lines, circles, and rectangles to doodle the upper and lower portions of your mobile phone.
Doodle additional lines on the side of your mobile that will represent the external buttons. You can either use straight lines, angles or even arcs for this purpose. Then on the screen of your mobile phone doodle a circle, four angles, and a closed arc shape for the “incoming call” symbol.
Time to add some small details to your mobile phone doodle. Use short straight lines to create a shading effect as shown in the example below.
The final step is to add some color to your doodle. Use either complementary colors or various shades of the same color. Often a light blue color works well to show a glass or reflective surface.
