The last Casio G'zOne handheld to come our way was the Commando, a military-grade device that marked the company's first foray into Android smartphones. Now it seems there's another one in the works, at least if a recent FCC filing is any indication. The Casio C811 looks to be a successor to the aforementioned Commando, with its G'zOne branding and features like WiFi and GSM world phone capabilities. Notably, the FCC document reveals the phone has Verizon-flavored LTE plus NFC support, both of which lead us to believe it'll likely be a mid- to high-end handset. Not much else is divulged from perusing the filing, but we're sure that whatever the C811 turns out to be, it'll be just as tough and durable as the rest of Casio's G'zOne offerings.
