Enabling Guided Frame isn’t difficult, but may not be expressly obvious if you don’t know what you’re looking for. The feature is part of Google’s TalkBack suite of accessibility tools, so to enable it, you’ll have to start by enabling TalkBack. This is done by going to your device’s settings menu, searching for TalkBack, and then turning “Use TalkBack” on.
If you don’t want to use the search function, TalkBack can be found by going to Settings, then selecting Accessibility, before finally selecting TalkBack which is found in the Screen Reader section. With TalkBack enabled, Guided Frame will also be enabled by default.
To actually use Guided Frame, you’ll have to open the camera app. From there, select the camera you want — be it one of the outward-facing cameras or the front-facing selfie camera — and point the phone at the soon-to-be subject of your photo. You can switch between the cameras by double-tapping the front or rear camera button.
You can then either follow the audio instructions your screen will provide, or the vibrations it uses to indicate useful adjustments to your camera angle. Once the phone thinks your shot is lined up properly, the photo will be taken automatically. If you want to manually take a photo, you can do so by double-tapping the volume button.
