There should be a select “All” option for deleting the people's photos from Gallery.
There should be select “All” option for deleting the people photos from
Gallery.
Here are the step and I think Apple can develop the software
for this feature.
1.
Navigate to Photos
2.
Select People option
3.
Select the person
4.
Select the photo which you want.
Here I am not seeing “All” option to delete the photos, because
if there are more than 1000 photos then it is difficult to delete one by one,
so there should be “All” option and Apple should provide this feature.
