amazon Samsung Galaxy S9 reviews
1. Design
Samsung Galaxy S9 follows the design of the previous product is Samsung Galaxy S8, and without too much change,
In terms of size they have little change, only when putting two products side by side you realize this.
The Galaxy S9 is slightly shorter than the S8 due to the lower edges being narrowed. Button positions are similar to those on S8.
The power button is on the right side, the left side is the volume down key and the dedicated button. The top is the sim card slot 2 in 1. That is a sim 1 memory card or 2 sim without memory card. Next to the noise recorder. Downside is the USB charging port C, port 3.5, recording and speakers of the machine.
The glass back has a 12-megapixel sensor, which measures the heart rate, and the fingerprint is placed underneath it instead of the S8, which makes it easier to access.
This device is also dust and water resistant standard IP68 as S8, Also note that S9 is thicker than S8, namely S9 is 8.5mm thick compared to 8mm of S8. Maybe Samsung does that so that the battery can drain heat better
2. Monitor and sound.
Galaxy S9 still has a 5.8-inch display, just like the S8, which makes the S9 slightly shorter than the S8 by 1.2mm. This boosts the screen ratio to 84.2%, compared to 83.6% for the S8.
Samsung still uses Supper Amoled screen on S9, so the colors are brilliant, the contrast is high and the outdoor display is quite good. The screen also features HDR 10 for better viewing of HDR support services such as Netfix or Amazon video.
Galaxy S9 2k high resolution for 568ppi pixel density. This resolution can be adjusted to Full HD plus or HD plus, depending on user preferences. Lowering resolution also extends the battery life.
The screen is protected by Gorilla Glass 5 both front and back, helping to prevent scratches quite well. Similar to the S8, the S9 screen is also curved to the side.
Stereo Sound System – Samsung’s first dual-speaker system (with built-in speaker and speaker) creates a large and quality stereo system. In addition, the speaker system is tuned by AKG and Dolby ATMOS support for live 360 sound effects.
3. Camera
The S9’s camera uses Sony’s image sensor on both front and back. The following camera has a resolution of 12 megabytes and has a variable aperture of F 1.5 to F 2.4. At a 1.5 F aperture, we can take very poor photos, even brighter than our eyes. It also has the ability to capture very good fonts even without two cameras.
Camera’s automatic mode, the camera will adjust the aperture to suit the shooting environment to make the best photo. In pro mode you can manually adjust the aperture and parameters such as shutter speed, ISO to make the image more accurate.
In addition to the regular 4k video recording, the S9 can shoot video at a slower rate of 960 frames per second at 720p resolution, similar to Sony’s recent offerings.
The front camera has a resolution of 8MB with a F1.7 aperture like the previous S8. The selfie ability is very good, removing the background and separating the subject from the background. The details of the eyes and skin color are quite accurate.

4. AR emoji.
This is a very new feature equipped to the Galaxy S9 when it brings quite a lot of inspiration in sharing emotions, images.

And you can interact with it. Also, after you have successfully scanned your face, the device can also give you a set of icons that are bold in nature and can be used on social networking apps like Facebook, FB Messenger.
5. Performance.
As usual, Samsung always uses the most powerful chip on its product. As in previous years, in the US market, the Samsung Galaxy S9 and Samsung Galaxy S9 + will use Qualcomm’s Snapdragon 845 chip while the international version will run Exynos 9810 chip manufactured by samsung.
Both processors are 64-bit chips, 10nm process technology and octahedrons. Normally, Samsung’s Exynos chips are rated as superior in performance, and in gpu graphics, they are lower than Snapdragon and probably this year is no exception.
The Snapdragon 845 is equipped with the new Adreno 630 graphics chip (GPU), which is expected to be 30% faster than last year’s Snapdragon 835 chip. In contrast, ARM Mali GPUs with Exynos 9810 chips are up to 20% faster than their predecessors.
This year’s RAM has also been slightly upgraded to 6GB, but only for the larger Galaxy S9 +. Meanwhile, the “brother” Galaxy S9 will remain the same 4GB of RAM as in 2017. This gives the company a clearer distinction between the two options, higher prices will also be reasonable for the Galaxy S9 + . The storage for both is still at 64GB, which supports expansion via micro SD memory card up to 400GB.
6. Battery life.
Samsung Galaxy S9 is equipped with 3000mAh battery like S8. Actually the battery life of the S9 is not different from the S8, the screen time of 9 hours 21 minutes at 50% brightness that same S8 last year.
In the test video player S9 can last 14 hours 25 minutes when playing 1080p video at 50% brightness and 50% volume, connected to the aircraft mode. The result is less than 16 hours 20 minutes on the S8.
Samsung Galaxy S9 supports fast charging through USB C and wireless port. Charge time is about 80 minutes from 0% until the machine full. The charger comes with 5V 2A output.
