Update: Samsung's S9 and S9+ have launched, but Australian avaiability isn't until 16 March 2018 - more detail at iTWire colleague Sam Varghese's article here.
Original story continues:
If you can't wait for the official launch of Samsung's Galaxy S9 and S9+ smartphones, then the leak of at least one of Samsung's launch videos has plenty of info, taking away some of the surprise.
You can find details on how to watch the presentation live here, which for Australians is 4am AEDT Monday February 25, but is on Sunday February 25 in most other parts of the world. No doubt the launch video presentation will be available to watch in full as a replay, as is always the case.
Of course, there have been all manner of leaks over the past few months already, but launch time is when things are finally confirmed, where BS walks and the truth talks.
So, what are the rumour-mongers saying, and what does this mysterious launch video look like?
Until then, here's that launch video:
So, what else is expected?
Well, we can start off with the observation that the S9 and S9+ plus seem to look almost identical to the S8 and S8+ plus, but as well leaked, the fingerprint sensor is finally centrally located under what appear to be two cameras, as it should have been in the first place.
That camera, according to the video, has a built-in text translator, something you can do with the Google Translate app.
The latest Qualcomm Snapdragon 845 processor is supposed to be installed, although this is probably going to be in the US only, with the rest of the world presumably set to get Samsung's equivalent Exynos 9810 processor, with an Adreno 630 GPU.
Four GB of RAM and 64GB storage is expected for the S9 model, while the S9+ is meant to come with 6GB and 128GB storage as standard, with 3000 and 3500mAh batteries respectively.
IP68 water and dust resistance is also expected to remain, as is currently the case with the S8 and S8+ models.
A new DeX device is seen in the video, and lets you turn your S9 into a desktop computer, but this time, the screen is a mousing surface, and you can use an onscreen keyboard, with the DeX unit plugged into a larger TV.
It's a clever update to the original DeX and hopefully its something that the S8 and Note 8 devices can also use, but we'll just have to wait and see, as it will probably be an S9 exclusive.
In the video, we see new multitasking features where apps can be paired, and there's a further emphasis on Samsung Knox for enterprise safety - something important in a world of Android malware.
Qualcomm's X20 LTE modem capable of 1.2Gbps 5x carrier aggregation capability is set to be included, with Quick Charge 4+ also expected to be included for ever faster battery charging - 50% charge in just 15 minutes.
There are rumours of Animoji-style capabilities, faster facial recognition, variable-aperture cameras, new 4K HD video recording at 60FPS and more.
There's plenty more, so instead of further rumour-mongering, all will be revealed in a few hours, but it will be the most advanced Android competitor to iPhones yet - and probably the priciest Androids yet.
