No button

I by far love Snapchat over all other social media. I deleted every other social media I have, and use just Snapchat. BUT when snap chatting people when o double click to reply and the picture screen pops up theres no button to take the picture, unless I use a filter to take it. BUT half the time the filters wont even pop up. Please fix what ever it is making this happen ! #frustrated
