Hello, this is Akash Patil owner of Samsung M01(SM-M015GD). I have purchased this smartphone recently in the month of October and at the end of month I got the update for Security patch level for September 1st 2020 even though it has to roll for the month of October. And still this smartphone is running on Samsung OneUI 2.0 although other Galaxy phones are running on OneUI 2.5. And I don't get monthly update for the security patch level.
Please take note of it and provide software and security patch level updates to smartphone galaxy M015GD device.
Please do the needful.
Only selected Samsung premium smartphones are eligible for monthly security patch while others for quarterly security patch update. Just go through the link(https://security.samsungmobile.com/workScope.smsb).
Check on settings > Software update or ask it from whatsapp customer support. Android 11 will be rolled out for your device in June of 2021.
