Google announced it will no longer support the Tango project from March 1

Google Project Tango
In February 2014, Google introduced Project Tango, an Augmented Reality system designed for use on mobile devices. Now, Google announced it will no longer support the project from March 1, 2018.

Termination of support does not mean Google closed the opportunity for the development of Augmented Reality (AR) technology. That means Tango is being replaced by Google ARCore based software, different from hardware-oriented Tango.

Tango became popular in June 2016 when Lenovo Phab2 was launched as the first Project Tango phone. With a large 6.4 inch screen. When launching Phab 2, Lenovo is demonstrating an app that lets users shoot furniture from commercials, and showcases its looks in different rooms, from different angles.
As early as 2017, Asus ZenFone AR was launched with support for Project Tango and Google's VR platform, Daydream. Supported by Qualcomm Snapdragon 821 processor, the phone is now no longer marketed by Verizon, equipped with 23MP camera with the sensor Sony IMX 318 and Optical Image Stabilization (OIS).
Camera motion tracker and depth detection is also equipped with Asus on the back of the phone. The phone is equipped with a 5.7-inch Super AMOLED screen and 1440 x 2560 qHD resolution. Now Google is shifting its focus to ARCore, and software is a key driver in the realm of AR. That means Google will roll AR as a feature on a large number of Android devices in the future.
