Unfortunately, the software and to some extent the network assumes frequent upgrades.

Despite having a relatively newish s4, the number of apps that simply won't work with my phone is astonishing. And once I passed the 2-year point of ownership, the number of network glitches has noticeably increased (dropped calls, messages taking hours to go through, loss of 4G for hours for no apparent reason).

I wouldn't be surprised if some of these glitches are intentional.
