The terminal operation is unstable.
･
Instability may be caused by
applications that you installed after
purchasing the terminal. If the symptom
is improved when you boot the terminal
in safe mode (near default state),
uninstalling the installed application
may improve the symptom.
To boot the terminal in safe mode, press
and hold
p
for over a second with
the terminal OFF until XPERIA logo
appears, and then touch and hold
m
at the bottom until the terminal
vibrates once. When safe mode is
booted, "Safe mode" is displayed at the
lower left of the screen.
To exit the safe mode, turn power OFF
and then ON.
* Back up the necessary data before
using safe mode.
* Some widgets that you created may
be removed.

state. To use ordinarily, exit the safe
mode.
