September update done. No issues so far. Some things to keep in mind:
1) Once the phone reboots (after update process), leave it that way around 15 to 20 min. Give some time for the phone to settle down, may lag significantly during this period (probably because the update is big).
2) For some reason, my memory card was not getting detected after installing update (I have a standard Samsung EVO Plus Class 10 sd card). If this happens, just manually reboot the phone and it will detect it.
After rebooting to detect memory card, the Gallery app may take some time to populate the folders from memory card. As I have a 256 GB memory card, it took around 15 min. to show the folders. It will take less time depending on your memory card size.
3) Clearing the 'Cache' from Recovery menu is recommended for smoother performance (I do this after every security update).
And I Factory Reset after every major OS update.
4) It seems Samsung Knox Privacy Policy also got updated (Secure Folder is working fine):
Overall, the update is fine. No issues. All the vital elements like camera, sound, display are working fine. No issues with sim card / data / Wi-Fi / Bluetooth.
You can go ahead and update it !!
