Why scrap them?
I agree it's poor of Microsoft to drop support so early, but most Android phones in a similar price bracket only get updates for a year or two after release if you're lucky. Unsupported Android versions are more vulnerable to exploits than a phone running Windows Mobile 8.1 due to security by obscurity. If the phone works and runs the apps you need then just continue using them!
