Samsung delayed the Galaxy S8 and S8+ announcement last year. Usually, the company took MWC stage to showcase their latest Galaxy S product every year but that wasn't the case last year. The company delayed announcement till March to double check the quality after the Galaxy Note 7 battery fiasco. However this year Samsung is all set to take their traditional stage once again to unveil new Galaxy S smartphones this year.

From what we know so far this year Samsung will be releasing two new Galaxy S smartphones as Galaxy S9 and S9 Plus. Both the devices are internally codenamed as "Star". The Star is in the development phase for quite some time that's why we have been hearing a lot about the Galaxy S9 series in last few weeks.

Like always whenever a new flagship announcement is around the corner, we round up all the details to give our keen readers a better picture of the upcoming device so they can know all the details ahead of official announcement. Today we will round up all the details of Galaxy S9 and S9+ to give a brief description of the upcoming next big smartphones from Samsung.

Samsung officially recently confirmed the upcoming Galaxy S9 series announcement on February 25. The company not only confirmed it via a tweet but also the company starts sending invites for the launch event. Like always, the company will hold the announcement event just one day ahead of the MWC. The MWC 2018 will kick off from February 26th. Though the company didn't bluntly confirm the upcoming Galaxy S series smartphones name instead the invite has numeral 9 which clearly indicates what to expect from Samsung.

Samsung Mobile President DJ Koh already confirmed at CES 2018 the Galaxy S9 will be showcased at the February trade show. Now as far as release is a concern, the well-known Evan Blass stated the pre-orders will kick off from March 1 in most of the regions with a release from March 16. The alleged Galaxy S9 and S9+ already cleared FCC hurdle, this means the devices are ready to be released in the USA.

Those who are eagerly waiting for a drastic design change they might disappoint with the Galaxy S9 series. Samsung doesn't have plans to completely revamp the Galaxy S9 from last year Galaxy S8. The overall aesthetic of Galaxy S9 expected to remain same with few refinements to differentiate it from the predecessors.

According to Blass, this year Galaxy S9 series devices will bring minor change in design as opposed to predecessors. The front-facing design will retain full front dual curved display like last year. All three edges will remain except the bottom edge which is expected to be trimmed slightly more. The major change will be in the rear design.

The first prominent change will be the placement of fingerprint scanner. One of the major reported problem with the last year Galaxy S9 series was the awkward position of fingerprint scanner right next to the camera module which often results in smudges on the camera module. Samsung heard all the criticism now they are replacing the scanner to a better position below the camera sensor. It's far better from the predecessor's positioning. We have seen a number of leaks in past which confirms most likely it will be the final design.

Samsung already opted this design for the latest mid-rangers Galaxy A8, A8 Plus. The new position in easily accessible and most likely will be appreciated by Samsung fans. The Galaxy S9 expected to be adorned with single rear camera setup whereas the Galaxy S9+ is expected to have dual vertically placed cameras. Like the predecessors, the Galaxy S9 series will also be IP68 certified which brings water resistance up to 1.5 meters for 30 minutes.

Samsung once again will opt the full front-facing Infinity display with minimal bezels which they introduced last year with the Galaxy S8. The Galaxy S9 rumored to have 5.8-inches display with 18.5:9 aspect ratio whereas the Galaxy S9+ expected to have 6.2-inches display with same 18.5:9 aspect ratio. The devices are compact with large displays.

Like last year most of the smartphones expected this year will have all bezel-less design. As far as display is a concern the South Korean media ETNews confirmed Samsung will retain the same display like the predecessors. This year we heard rumors that Y-Octa display tech is in works to slim down the display panels. Once again the Galaxy S9 will support HDR but this year it will be more beneficial as there is enough content available in the market to get full use of HDR support.

With the Galaxy S8 and S8+, Samsung introduced the Iris scanning feature as an alternative to the fingerprint scanner. This technology will be further enhanced with this year Galaxy S9 series, we can expect improvements. The Galaxy S9 is rumored to have a 3D camera on the front. This year Iris scanner from Samsung will have a better resolution to perform better in low-lit conditions as well as when the user is wearing glasses. The recent report also suggests that Samsung have plans to make Iris scanning compatible with the Pay apps.

The Exynos 9810 was recently announced by Samsung, the Galaxy S9 most likely the first smartphone from Samsung with this chipset. Samsung also stated the chipset is capable to create 3D faces which could be an indication that Samsung might bring facial recognition feature as well. A number of renders showcased a number of sensors on the top bezel, this could be for better 3D scanning.

Its never easy to compete against Samsung on the camera front, with each new iteration Samsung always try to bring the best on board to compete against rivals. The Samsung Galaxy S9 invite clearly highlights Samsung main focus is cameras this year. The invite has the caption "The camera. Reimagined."

As per recent reports this year Samsung most likely will be bringing a 12MP rear snapper for Galaxy S9 with dual pixel technology, its something pretty common with the Samsung flagships but what makes this setup interesting is the inclusion of variable aperture feature. In low-lit conditions, the aperture will be f/1.5 whereas in bright conditions the aperture will automatically switch to f/2.4. The slow-motion videography will be further enhanced with this setup.

According to ETNews the Galaxy S9 Plus most likely will have dual 12MP sensors with variable aperture. The device rumored to support slow-motion videography. Up front, the selfie-camera is expected to be an 8MP module with a dedicated iris scanner alongside it. For the first time, Samsung will be bringing two different camera setup on two variants of Galaxy S series. Almost all leaked images suggest single camera setup on the Galaxy S9 and dual cameras on the Galaxy S9+.

Being the flagship devices, the Galaxy S9 and S9+ will have the latest best hardware on board. The Qualcomm's and Samsung Exynos latest chipset will be on board to power it. The Qualcomm's Snapdragon 845 will be powering the US variant whereas the rest of the world will receive the Exynos 9810 driven device. The recent report from ETNews suggests that Samsung have plans to adopt SLP method for Galaxy S9 mainboard designing, this setup will help the company to free up more space under the hood which most likely will allow Samsung to include a larger battery cell.

The Exynos 9810 has integrated NPU to handle the AI tasks efficiently as well as it will save power of the main processor. We can expect better battery life with the latest chipsets. Apple and Huawei latest SoCs have special dedicate Neural processing units for better handling of AI tasks, on the other hand, the latest chipset from Qualcomm and Samsung have integrated Neural engines. The integrated Neural engine will be used to power up by Bixby AI assistant and facial recognition.

Samsung Galaxy S9 box allegedly leaked which suggests once again Samsung will retain the 4GB RAM and 64GB native storage. The memory will be further expandable via MicroSD card. It is still in the dark whether Samsung will retain the 3.5mm headphone for the Galaxy S9 series or not. There are reports in favor as well as against the headphone jack on the Galaxy S9. The audio setup is likely to be improved with the inclusion of DAC chipset and AKG Bluetooth headphones straight out of the box. The alleged box also suggests AKG headphones within the box.

As I mentioned above the Samsung's new design of designing motherboard with bring free space that could be used to bring slightly large battery cell. A recent report from a Chinese source suggests the Galaxy S9 could have 3,200mAH battery cell but a recent Brazilian site listing suggests the same battery as the predecessor. So far it is still in the dark whether the Galaxy S9+ will also have larger battery cell or not.

If the capacity remains the same, the battery life will be improved due to better hardware and software optimization. For connectivity and charging there will be USB-C port.

Samsung yet to release a smartphone with Android Oreo straight out of the box and also the company yet not rolled out latest Oreo update for last year flagships. The Galaxy S9 likely to have Android Oreo with Samsung's custom UI layer over it. However, the custom layer won't be TouchWiz UI instead the company will bring UX version with exclusive features for Galaxy S9 owners. The Galaxy Note 8 was released with UX 8.5. At the moment it is still in the dark what kind of features Samsung will be bringing with the Galaxy S9 and S9+ custom UX. This year Samsung will bring Google Assistant as well alongside the improved Bixby Assistant.

As far as price is a concern, the latest report from ETNews suggests Samsung have plans to start taking pre-orders in South Korea from March 2, the pre-orders will live until March 8. The price tag is expected to increase with the Galaxy S9. The device rumored to cost between $890 to $930 in South Korea which is slightly higher than last year. As far as global pricing is a concern, it is still in dark how much this device will cost in the US and other regions.

At the end, we would like to hear our readers thoughts in the comments section below regarding the Galaxy S9 series rumors roundup and do you think we miss any key aspect of the upcoming Samsung's flagship? Stay tuned for more comparisons and previews in coming days.
