Using the touchscreen
A protective plastic sheet is already attached to the screen of your device when you
buy it. You should peel off this sheet before using the touchscreen. Otherwise, the
touchscreen might not function properly.
When your device is on and left idle for a set period of time, the screen darkens to
save battery power, and locks automatically. This lock prevents unwanted actions on
the touchscreen when you are not using it. You can also set personal locks to protect
your subscription and make sure only you can access content on your device.
The device screen is made from glass. Do not touch the screen if the glass is cracked or
shattered. Avoid trying to repair a damaged screen yourself. Glass screens are sensitive to
drops and mechanical shocks. Cases of negligent care are not covered by the Sony warranty
service.
