I just want to move the photo from my zte916 on board memory to the micro sd card so I could have more on board memory for apps, on board memory keeps filling up and I can't download any more apps
Did a quick search, try using this app looks good Files To SD Card (link).
(Sorry can't try it I currently don't have a microSD card on my phone)
As far as I know, only way to do this is using a file manager app. Look for the photos and manually cut and paste them to a new folder in your SD card.
