Essential Products founded by Andy Rubin has today announced that it’s ceasing operations and shutting down.

The start-up last August showed off a radical ‘GEM’ smartphone. The prototype was a narrow candy bar-style touchscreen device.

In a tweet the company confirmed “Despite our best efforts, we’ve now taken Gem as far as we can and regrettably have no clear path to deliver it to customers. Given this, we have made the difficult decision to cease operations and shutdown Essential.”

Essential was founded by former Google executive Andy Rubin in 2015. The essential phone was the first devices to feature a minimal notch for the front-facing camera.

In a series of four videos, the easential team showed off the work they had made with the “Gem” phone. The device included a portrait keyboard with staggered keys. The prototype included a 48MP “smart zoom”.

Your PH-1 will continue to work but we will not be providing any additional updates or customer support. Current Newton Mail users will have access to the service through April 30, 2020.”
