Supported means many different things. Ideally, I want to know if the device is going to last, or if it's going to end up bootlooping and being a big PITA like the Nexus 5X, before I buy it. That requires that it be on the market for a considerable amount of time. In this case, the 4a 5G is discontinued after less than a year in the market; it may continue to be sold, but likely not for very long.

Free repair if that happens is nice, but also not that helpful unless being out a phone for a week is fine, and losing your on device data is fine.

Assuming you bought one on launch day, that's just-under 4 years of support. That only looks good by the awful standards of Android -- you can expect 50%+ more for Apple's phones, which you'd think Google could at least equal.

Apple providing 7 years of official support, i think.
