Yes, maintenance mode not just maintenance. With Maintenance mode on you can send your for phone for repair without doing a factory reset and wiping out all your data because no one would have access to it.

That's really weird because my Note 20 Ultra got the Android 13 and OneUI 5.0 before my Note 10 lite and A53 5G. Actually got the December update on my A53 5G yesterday like 2 weeks after my Note 20 Ultra and it has the maintenance mode but not the Note 20 Ultra
