■ Terminal operations
Trouble Check and remedy
The terminal, etc. become hot while
operating/charging
·
While operating or charging, or when you use applications etc. for a long time while charging, the terminal,
internal battery or adapter may become hot. There is no safety problem and you can continue to use it.
The operation time provided by the
battery is short
·
The operation time provided by the internal battery varies by the operating environment and internal battery’s
deterioration.
·
The internal battery is a consumable part. Each time it is charged, available time with each charging reduces. If
the operation time is extremely short, even in a fully charged state, see “Repairs” on the rear cover of this
manual or a repair counter specified by DOCOMO.
The terminal does not operate when the
touch panel is tapped or buttons are
pushed
·
Is the terminal in sleep mode? Cancel sleep mode by pressing
T
(P. 21).
·
Force-restart the terminal. Press
T
for at least 10 seconds to force-restart the terminal (P. 21).
Screen response when the touch panel
is tapped is slow
·
When large amount of data is saved in the internal storage of the terminal or transferring large-size data between
the terminal and microSD card, the reactions on the screen may be delayed.
Time is incorrect
·
The time on the clock may become fast/slow if power is left on for a long period. Check that “Automatic date &
time” (P. 83) is marked, and turn the terminal back on in a location with a good signal.
Terminal operation is unstable
·
It may be caused by applications installed to the terminal after purchase. If problems improve when you start in
Safe Mode, problems may be improved by uninstalling the applications.
* Safe Mode is a function to activate the phone in a mode similar to default.
·
To start Safe Mode
1. Turn off the terminal
2. Press
T
for 2 seconds or more with the power of the terminal OFF, and then press and hold
-
(Volume
down key) from when the logo of “NTT docomo” appears until the terminal starts up
* When safe mode is bo
oted, “Safe mode” is displayed at the lower left of the Home screen.
* T
o 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 usual active state. To use ordinarily, exit the safe mode.
·
Options for developers are designed especially for development; configuring them may cause the terminal or
applications in the terminal not to operate correctly.
Applications cannot be operated
properly (cannot be activated, or errors
occur frequently, etc.)
·
Are there any applications being disabled? Enable disabled applications, then retry to operate (P. 76).
