It's no secret that LG is debuting its fourth G-series flagship tomorrow, the G4, because, well, LG is one of the most transparent companies around when it comes to hyping its products prior to a launch. Whereas your Samsungs or HTCs won't even discuss the name of their upcoming devices — a name everyone already knows well ahead of time — LG plainly tells its audience what to expect and teases plenty of details before the actual announcement.

There has, however, been some confusion regarding the actual specifications of the LG G4 debuting in simultaneous launches in cities around the globe, mostly due to a microsite which slipped out into the wild two weeks ago. While the images contained within were indeed accurate, the specs table was filled with placeholders containing mostly features of the G4's predecessor, the G3.

Thanks to a trusted source, Mashable has been able to obtain the actual Android 5.1 "Lollipop" device's specs, and they paint a picture of a solid, if iterative, upgrade — with the phone also maintaining a pair of features suddenly absent from rival flagships like the Samsung Galaxy S6 and S6 Edge flagships.

Physically, at 5.9 x 3 x 0.4 inches, the G4 is slightly larger in every dimension than the 5.8 x 2.9 x 0.35-inch G3, though at least the increase in thickness can be attributed to a shape that borrows the gentle top-to-bottom curve from its G Flex linemate. But at 5.5 ounces, it's just 0.14 ounce heftier than the current model.

While the screen stays the same size, at just a hair below 5.5 inches, and the same Quad HD (2,560 x 1,440) resolution, it employs new display technology to improve several attributes associated with image quality.

In a welcome move, LG has eschewed Qualcomm's top-of-the-line, but controversial, Snapdragon 810 processor in favor of the 808 model, probably to address the overheating issues which caused Samsung to bypass the chipmaker altogether in favor of its own chips to power both G6 variants.

Like the G3, G4 ships with 3GB of RAM, this time of the DDR3 variety. Storage consists of 32GB eMMC non-volatile flash memory, and unlike the latest Galaxy S phones, a microSD slot for expansion. Also unlike the sixth-generation Galaxy phones, the G4's 3,000 milliamp-hour (mAh) battery (rated for 440 hours of standby and 14 hours of talk time) is indeed user-swappable.

This year's optically stabilized, laser focus-assisted camera has jumped to 16 megapixels, and LG has been making no small amount of noise about its f/1.8 maximum aperture lens; the company notes that an f-stop variance of even 0.1 makes a difference here, a thinly veiled shot at the f/1.9 cameras on the Galaxy S6 and S6 Edge. Getting a big boost is the front-facing selfie cam, going from a rather low-res 2.1 megapixels to a reported 8 megapixels this cycle.

In terms of wireless connectivity, all the requisite boxes have been ticked, with the LTE-Advanced-capable handset featuring 802.11 a/b/g/n/ac flavors of Wi-Fi, Bluetooth 4.0, NFC, and wireless charging (quick charging is available when plugged in).

It's one thing to read a rather dry laundry list of specs, but it's quite another to watch the unveiling live, with all the features presented in context. There are sure to be a few surprises to be learned tomorrow as well (though the leather backplate option is clearly not one of them), along with the all-important pricing and availability details, so enjoy the show.
