1. I take a screenshot and a small thumbnail appears on the bottom left
2. Click it and open it
3. I want to share it so I clicked the icon and choose mail
4. Typed stuff (recipient, subject, content)
5. Switch to another app (or let the phone lock) and it’s gone!
6. There is no way to find it anywhere
   (I’d expect it in mail Drafts, but it’s not there)

Data loss!

Don’t use that screenshot feature until they fix the data loss.

The work-around it is to NOT action #3 (clicking the mail icon from the screenshot). You have to take the screenshot as normal, then copy it from your album into a new email draft.
