Instagram added portrait mode called “Focus” in the latest update. You can access it at the bottom of Instagram’s camera. But it won’t work on all Android devices, though. Instagram just says “select” phones.
Portrait mode is becoming increasingly popular and smartphone makers are selling it as a feature. Portrait mode normally needs 2 cameras to sense the depth of object and blur the background. But last year Google showcased how it can be achieved with just one camera on their pixel 2 with ai.
Now Instagram has taken Google’s lead and made portrait mode with similar technology.
