Android One, Google’s platform for developing nations is said to be get the new Android OS version soon after it is released. The next major release of Google’s mobile OS, Android Nougat 7.0 is set to release in the coming month, so you may want to know whether your Android One phone will get the Android Nougat update. Below is the list of Android One phones getting Android 7.0 Nougat update.
Of course, Android One runs the latest version of OS and get the new version soon after it is released. However, the situation has changed now with the Android 7.0 Nougat. Nougat requires certain hardware requirements to run the new OS. Also, the hardware manufacturer needs to confirm the capability of device to run the new OS, so it is sure that not all Android One device are capable of running the new OS.
Note: The below list is my opinion and put together based on various information available from the Internet.
General Mobile 4: Google already confirmed that General Mobile 4 Android One phone will get the Android 7.0 Nougat update, soon after it is been released (preview of version of Android Nougat already available for the device).
Lava Pixel V1: Based on the General Mobile 4 hardware specification, the Lava Pixel V1 Android One phone (sold in India) most probably will get the Android 7.0 Nougat update. The hardware spec of Lava Pixel V1 is almost identical to General Mobile 4
Micromax Canvas A1, Karbonn Sparkle V, etc.: Because of the limited hardware specs, Android One devices, such as Micromax Canvas A1, Karbonn Sparkle V and Spice Dream Uno (sold in India) have very little chance to get the Android Nougat 7.0 update.
Also, there is very little chance to get the Android 7.0 update for Cherry Mobile One, Nexian Journey One, MyPhone Uno, Symphony Roar, etc., because of the hardware limitations.
