If you want to delete photos permanently from your phone, there are a few different ways to go about it. The first option is to use the Photos app on your phone. Open the Photos app and select the photos you want to delete. Tap on the three lines in the top left corner of the photo, and then tap on “Delete Photo.” If you want to delete all of your photos at once, you can use a third-party app like Clear or Erase. Open the app and select all of your photos. Tap on the trash can icon in the bottom right corner of each photo, and then tap “Delete All Photos.” ..
