Help... just discovered that my wife's Galaxy S9 (SM-960U), purchased unlocked two years ago through Amazon, has NEVER updated. It's forever stuck on Android 9, One UI 1.0, with the latest security patch from June 1, 2019. OTA update tells me the phone is completely "up to date".
Hi, I am sorry you are having issues with getting updates on your S9. Can you provide the latest software version it says you have? Also, give this article an attempt just in case: https://www.samsung.com/us/support/answer/ANS00077582/
Please let me know if this helps.
Neither OTA nor Smart Switch can find any updates to a phone forever stuck on Android 9 / One UI 1.0 with a June, 1, 2019 security patch. What specifically do you mean by "latest software version"?
