Read the tips below to help you take a proper measurement or watch the video below.
Tip 1: Sit down and relax
Sit down and relax and rest your arms on an even surface such as a table while you carry out the measurement. Do not move and try not to talk whilst taking the measurement.
TIP 2: Do not press down too hard on the camera
Do not exert an undue amount of pressure on the camera when placing your finger. A gentle touch is more than sufficient.
TIP 3: Remove the cover of your smartphone
If you carry your smartphone in a protective cover, make sure you remove the cover. This will improve contact between your finger and the lens of the camera.
TIP 4: Cover up the lens of the camera, not the flash light
Do not place your finger on the flash light, as this may get very hot.
TIP 5: If your smartphone has more than 1 camera,
select the camera that is nearest to the flash light.
