If you're eager to get upgraded and have experience with ROM flashing, you can turn your SM-A530W into a 9.0 unit with more than you'll get in a month from now. Fm radio, built in auto call recording, various teaks like camera shutter toggle and real-time data speeds... go to xda for everything needed. If you've never tried something like this before i'd suggest you don't do it. Start out with your basic twrp install and root what you have now. Maybe after 5 bootloops complete with desperate posting online... too risky.
