The new Android that everyone expected to be called Nutella but turned out to be Android Nougat is almost certain to be released on August 22nd. We already knew it was coming in August, but now they are two very good signs showing this particular one date circulation.
The Android Central reports that a Canadian carrier is reporting an 'Android N Update' for Nexus 6P and Nexus 5X devices on this date.
In addition, LG, which will release the first new Android phone to be run on Android 6 on September, gives access to OS testlers from Korea (G5 tested) by 22th August.
To be clear, the August 22nd update will most likely only roll out to Nexus phones. If you are impatient, for now you can only download the beta versions, which are close to the final public ones builds, but it looks like you won't have to wait too long for her real final version.
