A new LG device rocking a Qualcomm Snapdragon 800 processor has just passed through the FCC and it may well be the Google Nexus 5.

Amid lots of rumors and speculation regarding Google's next-generation Nexus smartphone, a new handset from LG has stopped by the FCC. LG made the Nexus 4 last year and it is widely believed that it will also make the new Nexus smartphone, dubbed the Nexus 5.

The folks over at Engadget have examined the FCC documents and pointed out several intriguing details, but not all of them could be verified at this point.

"Certainly, we don't want to just assume that every LG phone getting Federal approval for the foreseeable future is an N5, but there are a few clues in the paperwork that give us plenty of reason to nail this down as the primary suspect," reports Engadget.

The handset in question seems to sport a 4.96-inch screen, measure 131.9mm x 68.2mm (no depth mentioned), a Snapdragon 800 MSM8974 processor and several LTE bands (2, 4, 5, 17, 25, 26, 41, compatible with AT&T, Sprint and T-Mobile). Other details mention a Qi charging coil, NFC, HSPA+ (petaband), GSM/EDGE (quadband), CDMA/EV-DO, Bluetooth 4.0, Wi-Fi 802.11 b/g/n/ac, and a 2,300 mAh battery.

"That's an amazingly healthy list of specs for your usual FCC submission, and the list of LTE bands is quite stunning as well. If it's not the Nexus 5, it's certainly going to be one heckuva flagship," Engadget further notes.

The device in the FCC filings has model number LG-D820 and comes complete with a confidentiality request and agent authorization, further lending credence to theories that it is the upcoming Nexus 5.

One FCC filing for this handset reportedly mentioned Android Key Lime Pie, but the updated listing no longer makes that mention. The handset is expected to launch with the just-announced Android 4.4 KitKat.

All things considered, the LG device that just passed through the FCC may just be the highly-anticipated Nexus 5, or whatever the next Nexus smartphone will be called. The high-end specs and features certainly seem like something Google would go for, but it remains in the rumor state for now.

The FCC filing is real and the device in question will likely make its way to the market soon, but it remains to be seen whether it will launch as the new Google Nexus smartphone.
