Hi,

It is not possible to make any changes to the Default View. It is used based on the "View" model. "Customized View" is already available to make changes. In order for Flash Light to be visible all the time, it will always be visible when you use the code below by removing it from the "if" structure.

flushBtn.setVisibility(View.VISIBLE);

You can make the flash button always visible by changing the location of this line in the DefinedActivity.java class. I hope it was useful.
