My BYOD Note 9 on AT&T is stuck on Nov 1, 2019 security patch level. I tried "software updates" but it doesn't seem to find any. Based on another thread in this forum, I contacted AT&T and they asked me to FOAD and contact Samsung since it is not a phone they sold me. Does this also mean, I can never get Android 10 on my phone? Is there a way to sideload the security patches and OS upgrades? Thank you!
