Nothing launched the Nothing Phone 3a and Nothing Phone 3a Pro on March 4, 2025. With this, we saw the standout feature that’s turning heads: the Nothing Phone 3a Essential Key. This is a dedicated physical button on the right side of the device below the power button. Lots of people compared this with iPhone’s Action button and Camera Control button.
But it’s a different thing altogether. It’s more than just a gimmick. The Essential key enables the AI-drive app called Essential Space. It is designed to make you more organised and retrieve content with just a click away.

The Nothing Phone 3a Essential Key isn’t perfect yet. Some critics are sceptical about its placement, which can lead to accidental presses as it’s just below the power button. It would be amazing if we could launch apps with this key, but right now, the function is not there. Nothing is super committed to making this Essential Space even more refined in the future.
The Nothing Phone 3a and Nothing Phone 3a Pro are both steal deals. This is because of the Snapdragon 7s Gen 3 Processor, 50-megapixel camera, and quirky design. The Nothing Phone Essential Key adds a layer of innovation that sets Nothing apart.
