AT&T U102AA User Manual page 63

Do not apply excessive pressure on the screen and the device to prevent damaging them
and remove the device from your pants' pocket before sitting down. It is also recommended
that you store the device in a protective case and only use the device stylus or your finger
when interacting with the touch screen. Cracked display screens due to improper handling
are not covered by the warranty.
Device getting warm after prolonged use
When using your device for prolonged periods of time, such as when you're talking on the
phone, charging the battery or browsing the Web, the device may become warm. In most
cases, this condition is normal and therefore should not be interpreted as a problem with
the device.
Heed service markings
Except as explained elsewhere in the Operating or Service documentation, do not service
any product yourself. Service needed on components inside the device should be done by
an authorized service technician or provider.
