My understanding Oreo is less RAM intensive on old phones. But I can't even get Holo Jellybean launcher to behave on this durable phone. And not in a position to throw it away and upgrade.
I believe the GZone Commando was a Gingerbread, Verizon only CDMA/EVDO phone, and long discontinued, so don't think many devs would be interested in working on it. I know this device because one of the American teachers had one, and found they couldn't use it in China.
