Mere hours after being unveiled in front of an excited if somewhat embarrassed (by the show, not necessarily the phone) audience, the Samsung Galaxy S4 has been spotted making its first mandatory FCC visit. Is that the dictionary definition of perfect timing or what?

Bearing the model number GT-I9505, this should play nice with AT&T and T-Mobile’s LTE networks, although it’s technically not the US-bound version. It is instead the 4G-enabled international one, carrying support for LTE Band 5, as well as an 850/1900 GSM radio and 3G connectivity on 850/1900 WCDMA.

The unusually limited number of FCC certification docs makes the I9505 look rather mysterious, but fortunately we already know almost all there is to know about it. It’s due out sometime in April with the highly anticipated Exynos 5 Octa 5410 8-core CPU inside and a PowerVR SGX 544MP3 graphics processing unit.

Details on pricing are still scarce, while the rest of the specs and features can be summed up as follows:

• 5-inch Super AMOLED display with 1,920 x 1,080 pixels resolution
• 2 GB of RAM
• 16/32/64 GB of internal memory
• 13 MP rear-facing camera with face and smile detections, as well as plenty of other exciting new features
• 2 MP front-facing cam
• Android 4.2 Jelly Bean with TouchWiz Nature UI
• MicroSD support
• 2,600 mAh removable battery
• Wi-Fi, Bluetooth 4.0, LTE, NFC
• 130 grams weight
• 136.6 x 69.8 x 7.9 mm dimensions

Our first vs posts, pitting the GS4 against the Note 2 and iPhone 5, are already live, with other exciting articles being in the works. Hopefully, we’ll help you decide if the S4 is better than the HTC Droid DNA, Nexus 4, Sony Xperia Z and Galaxy S3 once those will be published.
