Basics

Using the touch screen

Do not allow the touch screen to come into contact with other electrical devices.
Electrostatic discharges can cause the touch screen to malfunction.
To avoid damaging the touch screen, do not tap it with anything sharp or apply
excessive pressure to it with your fingertips.
The device may not recognise touch inputs close to the edges of the screen, which
are outside of the touch input area.
Leaving the touch screen idle for extended periods may result in afterimages
(screen burn-in) or ghosting. Turn off the touch screen when you do not use the
device.
It is recommended to use fingers when you use the touch screen.
Tapping
To open an app, to select a menu item, to press an on-screen button, or to enter a character
using the keyboard on the screen, tap it with a finger.
