Can I change the default file name of photo taken by camera?

as the title,

is there any reg setting can modify it ?

Thx ~~

My device, LG ks20, wm6.0~~~

thx again!!

Don't know if you can on KS20 but on HTC you can enable the option to save photos using date and time file name by editing the registry, but it also changes the default storage location.

\HKCU\Software\Htc\Camera\General\
EnableDCIM = 0
