How to clean Nokia 3120

Remove the back cover plate of the phone. To do this press down the lock as you slide the cover toward the bottom of the phone.

Once the back cover plate is removed, the battery should be exposed. Remove the battery by prying it out. This can be done with your finger-nail or a prying tool.

Using your fingernails or another tool, pry the front face plate out along its edges and corners.

If dirt has gotten inside the phone, both the lens and the case should be cleaned.

Once the screen is exposed, spray cleaning solution onto a soft cloth and wipe the screen.

Make sure to thoroughly dry the screen.

Repeat the cleaning process on the clear plastic connected to the face-plate.
