How do i transfer my picture's from dji app to my phone am useing Android

I the DJI GO 4app you have an arrow in the lower right corner.  When click it, you can see your picture and video.  When you look at a picture, you can download it to your phone by click the download button in the lower right corner of the picture or video.

Welcome to the forum just follow Jotne step up there and you should be great

Hi, thanks for reaching DJI Forum. We do apologize for the troubles. If the photos and videos are stored on the SD card, you can view them in the DJI GO app or download them to the mobile device and process them on a computer later with a card reader.
If the photos and videos are stored on the solid-state drive (SSD), you need to process them with a designed card reader. Do not store other data or delete the data on the SSD. We're here to help you with this. Thank you.
