Thanks for your inquiry. Once available, updates are released to Carriers and thereafter, it is at the Carriers discretion to release the update to customers. Since updates are released by Carriers in waves, we’re unable to determine when your device will receive an update. We appreciate your loyalty.
You can expect the Android Q update around the time all other Android phones have Android 12. With Samsungs very very slow update cycle it will pretty much never show up.
Don't hold your breath.
