It’s mid-September already and Samsung has already rolled out the latest Android patch with their own fixes to a number of models. The flasghips were next apparently, because the OEM has just started releasing the September security patch for the Galaxy S9, S9 Plus and the Note 9. Keep in mind that if you are in the US, the carrier versions always get the updates first and this month is no exception either. Sprint customers should be seeing the update arive on their S9/S9+ any day now, if they have not received it already.
The Galaxy Note 9 on the other hand, is only getting updated in Europe at the moment, with Romania, Netherlands and Switzerland being in the front lines, as mentioned by SamMobile. If you have not yet received the same security patch on your Galaxy Note 8, you probably need to check for it manually, because smasung had released it quite a few days back in a lot of regions.
The large update for the Galaxy Note 9 seems to be puzzling a lot of users though, as most of them could not find any significant changes in their devices, post the update. While this in itself should not be anything to be puzzled about, the 660MB size of the update is quite baffling! If you were expecting to get AR Doodle and the Live Focus features which the Note 10 has, this update is not going to bring them to your device undortunately, and the change log did not mention anything significant at all. So the question is, what on earth is this 660MB update packing, aside from the minor bug fixes and security certificate updates?
