When suddenly brought into a warm place from a cold place, or when in a
humid location, or when used where temperature suddenly changes (e.g.
near the air discharge port of an air conditioner), water drops (i.e.

Note that covering the light sensor with fingers or stickers will prevent the
sensor from responding to ambient brightness and operating properly.

If the display gets damaged, immediately stop use and contact an au shop
or Repair and Delivery Support Center. Keeping using it may cause injury.
●
Putting a sticker, etc. on the display or a key may cause malfunction or
shortened usage time. Also, doing so may damage the product.

If you put magnetized objects close to the product, the speaker section
sometimes emits sounds. This is not a fault.
