The J100 Series phones can white text on a dark background (dark mode) or black text on a white background. Using settings in a 46xxspecials.txt (see 46xxspecials.txt), you can control the mode used, and whether users can change the mode.

• This feature requires the J100 Series phones to run J100 R4.1.2.0 or high firmware. Phones on earlier firmware use dark mode.

Settings file command

Add the setting DISPLAY_MODE N to the 46xxspecials.txt file, where N is:

• 0 = Dark mode. User switchable.

• 1 = Light mode. User switchable.

• 2 = Dark mode. Not user switchable.

• 3 = Light mode. Not user switchable.

For example:

IF $MODEL4 SEQ J139 GOTO J1X9SPECIALS
IF $MODEL4 SEQ J169 GOTO J1X9SPECIALS
IF $MODEL4 SEQ J179 GOTO J1X9SPECIALS
IF $MODEL4 SEQ J159 GOTO J1X9SPECIALS 
IF $MODEL4 SEQ J189 GOTO J1X9SPECIALS
GOT END
# J1X9SPECIALS 
SET DISPLAY_MODE 1
#END

User control

If you choose to make the option user switchable, users can select  > Settings > Display > Display mode on their phone.
