Stuck on old Android
This is an issue with telcos locking down phones that they claim they're selling to you. You should never buy a locked phone. You will regret it in 6 months when you've hit a major bug and the telco offers to fix it with a $250 phone swap.
BTW, Apple stops providing security patches to older models too and offers no workaround other than switching to Linux or buying a new computer that isn't actually any faster.
Biting the hand that feeds IT
