Samsung's upcoming Galaxy S10 smartphone could be an impressive overhaul in design and features - here are 9 rumors about what it'll look like

The larger Galaxy S10 Plus model could come in two different variations, one of which will have 5G support, according to XDA-Developers, citing information it found in the code inside an upcoming software update for the Galaxy S9 Plus.

5G is a new wireless standard that promises extremely fast data speeds and potentially less congestion than the current 4G LTE standard is experiencing today. That means 5G data speeds will still be fast, even during times of peak data traffic.

So far, however, 5G availability is extremely limited and hasn't been fully deployed by most carriers.

A front-facing fingerprint scanner embedded underneath the display is perhaps the most hotly anticipated feature that could come to the Galaxy S10 — and the rumor mill says it's well on its way.

An invisible fingerprint scanner underneath the display would certainly add to the futuristic look and feel of the Galaxy S10. So far, some phones from Chinese manufacturers including Vivo, Xiaomi, Oppo, and Huawei have this kind of hidden fingerprint sensor.

One of the latest rumors claims that embedded fingerprint sensors will come standard on two of upcoming Galaxy S10 models, according to The Investor, and the lower-end model with a flat display will have a regular fingerprint scanner on the side of the phone. The rumor lines up with Ming-Chi Kuo's earlier predictions.

Samsung's own head of its mobile division DJ Koh said that the upcoming Galaxy S10's design will have "very significant" changes over previous Galaxy phones.

Koh didn't elaborate on what changes are coming to the Galaxy S10, but there could be a clue in a rumored change in the Galaxy S10's earpiece, which you'll see in just a moment.

The earpiece on the Galaxy S10 won't actually be an earpiece, according to ET News. Supposedly, phone call audio will be transmitted to a user's ear with vibrations emanating from the display, rather than using a traditional speaker.

Without a traditional earpiece, there would be no need for an opening from which sound can escape out. Fewer ports and openings could lead to a cleaner and more modern design, but it could also point to a clue that narrower bezels are coming to the Galaxy S10. It could even allow Samsung to make an all-screen front surface without the need for an iPhone X-style notch.

Still, the front-facing cameras and sensors will still need a hole to peek out of somewhere, so it remains to be seen how Samsung will accommodate with the Galaxy S10 design.

So far, the rumors suggest that the Galaxy S10 will have three rear camera lenses, and two front-facing cameras, according to Korean news outlet The Bell.

The Bell reports that the extra lens on the back will be a 16 megapixel ultra-wide angle lens, similar to the ultra-wide angle lens on LG G and V phones. This ultra-wide angle lens will come in addition to the 12-megapixel optical zoom lens and standard wide angle lens that Samsung's current-model Galaxy S and Note phones already have.

The dual-lens system on the front, meanwhile, could allow for an iPhone X-style portrait mode while taking selfies.

A face scanner will feature in the Galaxy S10 for unlocking the phone, and potentially also creating augmented reality stickers, according to The Investor — citing Samsung's partnership with Mantis Vision, a company that develops 3D sensing camera solutions.

It'll likely run on the latest and most powerful chip from mobile chipmaker Qualcomm, the Snapdragon 855, according to Phone Arena. Most smartphone models from 2018 are running on the current-generation Snapdragon 845.

The Galaxy S10 is also said to sport faster memory technology for both RAM and storage, which could boost the phone's performance.

First and foremost, it'll be surprising if the Galaxy S10 doesn't come with the latest version of Android — Android 9.0 Pie.

Samsung's phones usually sport a tweaked version of Android, with a slightly modified interface of its own. That interface to be called "TouchWiz," but it's been called "Experience" for the last few years.

Samsung's latest Experience 10.0 interface on the Galaxy S10 is said to come with a wide variety of design and function updates, which you can check out at XDA-Developers, or check out the video below:

Interestingly, Samsung apparently hasn't adopted the new navigation gestures from Android 9.0 Pie, according to what we know today.

If Samsung follows its usual smartphone release cycle, the Galaxy S10 will likely be announced in February and released to buy in March, much like the Galaxy S9.

As for price, few rumors exist, so it's hard to tell. Either way, it's likely to have a similar price tag as the current-model Galaxy S9, which starts at $720. Perhaps the smaller model with a supposedly flat screen may cost less, but at this point, that's pure speculation.
