I am using the Yahoo mail app. When I try to attach photos or videos it takes a really long time. I switched from the IPhone, which was really simple in this regard. Videos sometimes will take 20 minutes or more to attach and then they won't even be there when I try to send. Like they upload and then disappear. Here is my process: I go to the Gallery, select the video, hit the Yahoo icon and it opens a new email and a percentage box telling how much is complete. Often, it will then have 2 or 3 boxes like that with different percentages. Is it trying to attach it multiple times?
What is the best setting/size for photos and videos so that they are easy to attach to texts and emails?
