Clean the Touchscreen
The phone screens require minor maintenance, but you may need to clean the
screen periodically.
Before you clean the screen, disable it so you don’t activate phone functions while
you wipe the touchscreen.
Use a clean, dry, microfiber cloth—the kind you would use to clean glass surfaces—
to wipe the screen. Don’t use chemicals to clean the screen.
1. Go to Menu > Settings > Basic.
2. Select Screen Clean.
3. Wipe the screen with the clean, dry, microfiber cloth.
NOTE: If the screen is still dirty after cleaning, dampen a soft, lint-free cloth
with an isopropyl alcohol and water solution of 50:50, then wipe the screen
with the cloth. Always use the dampened cloth to apply the solution; never
apply the solution directly to the screen because the solution could seep
inside the screen or stain the phone. Do not use chemicals to clean the
screen.
4. To enable the touchscreen, follow the onscreen instructions.
