If I delete images with file explorer from DCIM/Camera and images are still in DCIM/thumbnails, will thumbnails images stay there? If they stay there, will something delete them in future? Does Xiaomi phones have something to delete thumbnails?
Will deleted images be safe in thumbnails folder?
Question
Answer
Thumbnails are not really the exact images you deleted. They are just the cached images of extremely low quality which your phone used to show you images with more speed. Your phone save a Thumbnail of image you open in your phone so that next time you open that image, it takes less time. Thumbnails have very small resolution and quality than original.
Clearing your cache memory will delete the thumbnails. Usually, phone don't have any automatic thumbnails deletion.
