This afternoon Google made it official, as they announced the name of the new Android N 7.0 called Nougat. however I can now tell you that your current android v4.4 Kitkat, Android v5.0 Lollipop is outdated.
Nougat is the nickname of the latest Android OS v7.0 which follows Android v6.0.1, meaning Android 6 never even had a proper 6.X release. Android v5.0 had 5.1[.1], 4.0 had 4.1 through 4.4[.4], 3.0 had 3.1, 2.0 had 2.1 through 2.3[.7], and 1.0 had 1.1, 1.5, and 1.6
And upgrade simply means better performance and optimization so don’t get stuck on Android 4.4 Kitkat, upgrade your device now.
Soonest we should start seeing Android v7.0 across OTA releases for various eligible smartphones… And for those smartphones that never smells OTA update, I guess you know what to do next.
