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. 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.
* Safe mode is not a normal booting state.
To use ordinarily, exit the safe mode.

Developer options are designed for
developers. If you set them, the terminal
