Old Android devices that cannot be upgraded is a headache for service that can't afford to lose customers who still use old smartphone.

One of the colleague once estimated that just giving a new Android phone to all customers who is still using annoyingly old phone is better solution than supporting old Androids. He calculated the cost of supporting old Android(amount of time wasted multiplies by engineer's wage). He concluded that it's actually cheaper for a company to give every old android users of our service a new phone than diligently supporting old Android versions. Also, it greatly improve the QoL of engineer.

Sadly, our company never executed this plan.

Well, salaries of employees are a fixed cost, so there wouldn't really be any money saved by giving away devices. At least, there'd be no money saved unless the company also then fired all of the engineers that were no longer needed because time didn't have to be spent diligently supporting old android versions.
