Send Photo as Mail attachment is Missing I have just had my phone rebuilt. 

I used to send a photo by clicking on the box-with-arrow below it and an app would come up to attach it to mail. 

This has now disappeared ?
When you are texting in the text box look to the left of the box and if you see anything there pull it to the right and it makes the camera icon visable. That is what my son showed me when I had the same question. I hope it works for you.
