Security update for one. Idk about 1-2 years, but if it doesn't get security updates I'm not getting email/sms/etc on it
But your email app will still get updates right? (I guess I'm using Gmail and assuming you are using something like it that gets updates too, but maybe I'm wrong.) Same with SMS - lots of apps that get updates. What's the exact issue?
You're on Android 4, so your phone is vulnerable. If you use your phone for anything important, I'd suggest getting that new phone ASAP.
