How To Record Snapchat Videos Without Using Your Hands
1. Turn Assistive Touch on by going to
Settings>General>Accessibility>Assistive Touch>Turn On
2. There is a tab below Create New Gesture click so that you can create a new gesture.
3. Press on one spot as it records. Make sure that you press it for more than 10 seconds. Just to be on the safe side because a Snapchat video is 10 seconds long.
4. Save Gesture as 'Hold' (or whatever you want it to be)
5. Open Snapchat
6. On the camera screen open the Assistive touch button and click the favorite button and select gesture like in my case it is 'Hold'
7. A black circle will appear and drag it to the camera button. Voila! It will start recording.
