Use Toggles instead of Buttons

[Sameer Sharma]

Using buttons for a camera app doesn't seem ideal, the currently has two buttons- one to capture(Clicks photo and disables stream) another to click new photo(Re-enables stream), this isn't feasible as both buttons always remains active and can lead to confusion for user and crashes and UI penalties for the app.

Hence a single toggle button which dynamically changes text & function according to interaction is needed.
