The original Samsung Galaxy Tab S tablet is less than two years old which means that it's still compatible with the current most recent Android release which is Marshmallow. Samsung hasn't said when it's going to come out with Marshmallow for this device but we've heard when the company is going to release Marshmallow for the original Galaxy Tab S.
According to our information, the original Galaxy Tab S is going to receive the Marshmallow update in the near future. Samsung is likely going to release this update in the third quarter so it can either arrive later this month or by August but it shouldn't take longer than that. Marshmallow is most likely going to be the latest major Android release for this tablet as it may not get Android Nougat, which is yet to be publicly released even for the most recent mobile devices.
