Acer E100/E101 Smartphone User Guide58
The application buttons
You may change the function of these button with the Buttons
application, but we recommend that you use the defaults
whenever possible.
Tip: The application buttons can be configured
to launch applications that you use the most.
To configure which applications to launch with
each button, tap Start > Settings > Personal >
Buttons.
Select the button you wish to configure from
the list, then select the program to assign to
the button from the drop-down list below.
Tap OK to confirm and save.
Acer strongly recommends retaining the
default settings. This avoids confusion when
using your smartphone.
Managing system certificates
System certificates are used to positively identify your smart-
phone to other systems.
Tap Start > Settings > System > Certificates to view all
certificates.
