Re: LG G3 Camera
Good info, I didn't know that. I'm guessing though, that the OP probably meant watermarking the date/time onto the photo (used to be done frequently for say, real estate agents).
If so, there are a lot of apps in the Google Play Store that purport to do that -- just search for "watermark photo date". I haven't tried any though. If that wasn't what you meant, please clarify.
