Step one:
Draw half a square on each side.
Step 2:
Then connect them with arcs, draw them down, and connect them with horizontal lines.
Step 3:
Draw a large circle in the middle.
Step 4:
Draw a medium circle inside the circle, and draw some small circles around it to serve as the phone plate.
Step 5:
Then draw two arcs on the right, one long and one short.
Step 6:
Connect them with arcs and pay attention to the changes in arcs to form the shape of a phone.
Step 7:
You also need to use a circle of lines to connect the phone and the phone base.
Step 8:
Finally apply a nice color and the phone is complete.
