It’s now just a matter of hours before Samsung shows up in New York City’s Times Square and unveils its much-anticipated Galaxy S IV. But it looks like someone’s already gone ahead and spoiled the surprise — again. The device has today been leaked in a gallery of high quality photographs posted to a Chinese message board, which come with a detailed list of specifications attached.

These photos are not from the same source as the previous Galaxy S IV leak, which also surfaced in China earlier this week. However, they do show off an identical device, and they’re good quality snaps — the best we’ve seen to date. The specifications also match up.

Here’s what we can expect from the device, according to the

• 4.99-inch 1080p display
• 1.8GHz eight-core Exynos 5 Octa CPU for Europe (Qualcomm Snapdragon 600 CPU for the U.S.)
• 533MHz PowerVR SGX 544MP3 GPU
• 2GB of RAM
• 16GB to 64GB of internal storage
• 13-megapixel rear-facing camera with BSI sensor
• NFC connectivity
• GSM/WCDMA/HSPA+/LTE
• Android 4.2.1 Jelly Bean
• 2,600mAh battery
• Dimensions: 140.1 x 71.8 x 7.7mm
• Weight: 138 grams

In addition to the above, the source claims that China’s Galaxy S IV will offer dual-SIM functionality, and that it will be the only market to get this — the rest of the world will see a single-SIM device, at least initially.

They also claim the device will offer the Smart Pause and Smart Scrolling features we’ve previously heard about, but these will also be left out in some markets for reasons we’re not yet sure of.

The device in these photos is identical to that that was leaked earlier this week, and it’s looking increasingly likely that this will be the Galaxy S IV. We had suspected it could have been a prototype merely built for testing, but in these high quality photos, the handset looks like much more than that.

It’s certainly surprising that Samsung couldn’t keep the device under wraps until its big unveiling, however. The Korean company went to great lengths to ensure the Galaxy S III wasn’t leaked last year, so we knew very little about the handset before it was announced. Although some of its specifications had been mentioned in rumors, its design was a complete mystery.

So why hasn’t Samsung been able to maintain that secrecy this time around? Well, that’s unclear, but it was always going to be hard as interest in the Galaxy lineup — particularly the flagship — continued to grow. Take a look at the iPhone, for example; Apple is famous for its secrecy, but even it struggles to prevent its devices from leaking now. There’s simply far too much interest in them.
