How to delete all photos from the iOS 7 camera roll WITHOUT importing them?

• I have 4000 photos in the camera roll
• I don't want import them into my MacBook's iPhoto or nowhere, so
• simple want delete them directly in the iPhone (iOS 7).
• selecting them one-by-one (you sure agree) is NOT very user friendly

What is the "Apple way" of doing this (usually) simple thing?

Solution 1:

On iOS 7

1. Open the Photos App and make sure you are in the “Photos” section from the three icons at the bottom of the screen;
2. Look at the top of the screen and make sure the view is “Moments;”
3. Now you can tap individual thumbnails one at a time to select them, or you can tap the word “Select” that appears at the top of each grouping to select an entire grouping.

On iOS 6

1. Go to Settings → General → Usage → Photos & Camera;
2. Swipe on the “Camera Roll” entry;
3. A “Delete” button appears.

This solution does not work on iOS 7 (last tested on iOS 7.0.4). It is probably a bug.

Any iOS, but using a computer

If you have iOS 7, you can use Image Capture on your Mac to delete photos from the iPhone without importing them:

1. Plug the iPhone to your Mac with the iPhone cable;
2. Quit iPhoto if it launches automatically;
3. Launch Image Capture;
4. Select the photos you want to delete;
5. Click the red icon to delete the photos.

Solution 2:

Works on ios7 - Plug your iphone into your computer and open it via My Computer - then find the photos file(s). Select all and then delete! Done!
