If you aren’t already logged into Snapchat, tap Log In and enter your username (or email address) and password.
Tapping and holding this button will take a video up to 10 seconds long. Tap the camera icon in the top right corner of the screen to change the direction the camera faces (e. g. , toward you).
You can change the font by tapping the font previews above your keyboard. Tap the Aa icon under the T icon to change if your text has a background or not. Tap the “Alignment” icon (or the icon of multiple lines) to change if your caption is aligned to the left, right, or center.
You can change the text color to black by dragging your finger all the way down to the bottom right corner of the screen. Dragging your finger from here to the bottom left corner of the screen and then up will change the color to grey.
You can also tap Done on an iPhone or the checkmark on an Android to save your text. You can tap and drag the text to move it on the picture. [1] X Research source
You can also send your Snap to your Story by tapping the square with a plus next to it on the bottom of the screen.
