Saving photos on to phone from camera setting

Hi apologies if this has been covered a thousand times and this is really, really basic (i have searched but I am also very new to this).

But can some explain how I can get photos taken from the camera screen on to the actually phone?

Currently I have a button that opens the camera and allows the photo to be taken but it doesn’t save anywhere.

Preferable I’d like it to save to a gallery within the app but i also do not know how to do this.

If anyway can help that would be great and once again sorry if this has been discussed many times previously.

Many thanks


Or another way.

How do i save a photo taken using the camera facility in an app to store on a seperate page in the app in a gallery?

Any help very much appreciated for this newbie.
