Hey bro, Your thought was wrong. This is not a software upgrade. This is a security update. ( once every 3 months). Note this: you can get many security updates once every 3 months in future. But you can't receive the one ui4. Because a30 's last upgrade is one ui3.1 okay.
Actually what happens in a security patch ?? Even though my device isn't eligible to one ui4 then atleast after security patch updates will i get random updates for apps in build like as if i updated to a new software ??
Your a30s is released with android 9. So, your a30s does have to receive 2 major os guaranty. So, a30s past the android 10,11. Finally 2 os 's you received. That's solved.
