Thread: MMS

Usually on Android:

If you already opened the image to view it large, then it'd be cached in the Photos app(or whatever image viewing app Samsung now use).
Open that app again to view the images again and long press the image to reveal the option to view it's details.

Images on Android are stored in a folder named DCIM.
You usually have an option to locate that folder on the phone storage space itself, or on an external card?
I think by default it stores them on the phone itself.

I set mine to the card(don't want to clutter the phone!) .. so my DCIM folder is located on the card, not the phone.

So to assist you with an exact location is going to be tricky .. as it depends on what you did when you set the phone up.

If you have Windows 10, it allows easy connection between PC and phone, that allows you to view the contents of the phone via the PC when connected via USB cable.
If you have installed the Samsung software to manage the phone, then I think this also did similar things, but lacking in flexibilty(as I remember it).

If you haven't used a program called MyPhoneExplorer, I reckon you're missing out!
