Hello, I recently got a S9 (refurbished) and when I went to update it from Android 8, it didn't have any updates. Knowing how my old S8 is on android 9 I was trying to find out what happened. I checked Smart Switch, didn't say it had an update. Tried resetting to factory settings 3 times (didn't work). Clearing the cache didn't help either, even though so many recommend it to me. After 2 hours i gave up and here I am. I have no clue what to do or how to get it to Android 9. I can't really get to a Samsung or Carrier shop to get them to flash it so I'm trying to find fixes I can do. Any help is appreciated!!
