Finally, Samsung has released a stable version of Android Marshmallow for the Galaxy On7. Both the On5 and the On7 was released in 2015 and was due for the update and it's good to see Samsung deliver it to the On7, albeit a little later than most users would have liked. There is no definite news as to when the On5 will be upgraded to Android Marshmallow right now, but we are pretty sure that it will be sooner than later. The Galaxy On-series is also rumoured to receive new handsets this year with more up to date hardware and software. However, they will still be named On5 and On 7, but with the 2016 moniker attached.
Go to Settings > About device > Software update and check whether the update has arrived on your On7 yet. If not, don't worry, OTA updates are sent out in batches and it may take a while before all smartphones receive the package. Once you have downloaded and installed the update on your smartphone, you can expect all the features that make Android M great, like Doze, Google Now on Tap, customizable app permissions and a new UI to name a few.
