Recently, all images that I either take with the camera, screenshot, or are sent/received via Whatsapp get shown as normal for a few minutes...then disappear!
In the Gallery, all the images turn dark grey.
In the Photos app, "Media not found" is displayed and Auto-backup is failing.
In Whatsapp, they appear black and when clicked a small blurry thumbnail of the image appears.
My phone is a Huawei Ascend G6, and the main storage is a 32GB SD card which has successfully saved other images in the past - it's just in the past month that this problem has been affecting any new images.
Please could anyone help me solve this issue?!
