Before I could edit file name *******.jpg. After 3.0 update now I can't. Just keeps the .jpg date and file name. I have a lot of pictures! Can't now tell what’s what?
Now Samsung UK told me this feature has been deleted. Rubbish🤬🤬🤬
you may use ES File explorer app
you may download from Galaxy Store
on the app → tap Photos → tap the folder → tap and hold the photo → hit rename
