OPTICXCESS — Review of Galaxy S20 Ultra, Samsung Mobile Phone with 108MP Wide-angle Camera

There are three things that immediately crossed our minds when we saw the Samsung Galaxy S20 Ultra: large, zoom, and expensive. This phone is arguably the largest Galaxy S phone to date.

With a total of 4 cameras that stand out behind the phone and the ability to take photos with magnifications up to 100 times make the Galaxy S20 Ultra unique compared to its siblings the Galaxy S20 and Galaxy S20 +.

Body of Galaxy S20 Ultra

The S20 Ultra is a really big phone, even rivaling the size of the Galaxy Note10 +. Fortunately, the width and thickness of the cell phone are still within the limits of tolerance for hand comfort but maybe this will be different for those who have small hands.

What makes it less comfortable holding the Galaxy S20 Ultra is actually its weight which reaches 220 grams. Often feel sore when using this phone with one hand such as when taking photos or relaxing on the couch.

Therefore it will be easier to use the Galaxy S20 Ultra with 2 hands. Using the Galaxy S20 Ultra with one hand is arguably a challenge.

For the design, this Smartphone still uses a design style similar to the previous series. The most striking design difference in this phone is the location of the front camera which is now in the center of the screen and a very prominent camera area.

All physical buttons are now on the right side of the phone and only consist of a volume control button and a power button. No more special Bixby buttons, for activation Bixby now integrates its function with the power button.

The headphone jack is also no longer found on the Galaxy S20 Ultra. If you want to listen to music on this cellphone then you need to use wired USB-C type headphones or use wireless headphones. Fortunately, in the sales box has provided AKG USB-C type headphones.

The cellphone is still coated with glass material on the front and back which is joined by an aluminum frame. Even though it’s filled with glass material, the cellphone doesn’t feel slippery when used. But of course it would be safer to use this cellphone with a casing which has provided flexible plastic material casing in the sales box.

If the phone is shaken, you will hear a sound coming from the camera module. From our search, this turns out to be common in these phones. This is probably due to the unique camera module. Interestingly, the sound will not be heard if the camera application is actively used.

Screen of Galaxy S20 Ultra

The Galaxy S20 Ultra uses a 2x Dynamic AMOLED technology screen with a camera hole in the top center of the screen and a flatter side of the screen. The screen quality is no doubt for a premium mobile class, bright and can display colors well.

Screen of Galaxy S20 Ultra

The position of the camera hole in the middle of the screen of this phone in our opinion is more comfortable and not disturbing compared to the previous series. Notification area on the screen is now more concise so that it can be maximized using the screen for the main content.

The Galaxy S20 Ultra screen supports resolutions up to WQHD + (3200 x 1440 pixels) and a refresh rate of 120Hz. But by default the phone will use FHD + resolution (2400 x 1080 pixels) and a 60Hz refresh rate.

You could say the high-resolution WQHD + is not too felt the impact for everyday use for some people. But for a refresh rate of 120Hz, the effect is very pronounced, the mobile animation looks smoother when this feature is active. Unfortunately, both WQHD + or 120Hz refresh rates will have an impact on the more wasteful use of battery power.

If you want to use a 120Hz refresh rate, the phone will lock the screen resolution at a maximum of FHD +. Samsung seems to lock the combination of using a 120Hz refresh rate and WQHD + resolution to protect the cell phone from excessive battery power usage.


For performance, the Galaxy S20 Ultra uses Samsung’s latest chipset, the Exynos 990 combined with 12GB of RAM, and 128GB of storage capacity.

As far as our experience using the Galaxy S20 Ultra found no obstacles in terms of performance. The operation of the phone is smooth and playing the latest games with maximum graphic settings is no problem.

When we tested the cellphone with the AnTuTu and Geekbench applications, the Galaxy S20 Ultra won a score of 511,871 in AnTuTu and a score of 898 for single-core and a score of 2,756 for multi-core in Geekbench. This score puts his cell phone in the ranks of the fastest performing mobile phones in the world.


The speakers in the Galaxy S20 Ultra are good for a cellphone. Dolby Atmos feature is available to change the quality of the sound produced according to the type of audio being played but if this feature is turned off the sound produced will be clearer.

For the cellular network, no problems were found as long as we used this Smartphone. When used for telephone calls, we can communicate with the other party smoothly.

The fingerprint scanner on this cellphone uses an in-screen scanner model and uses ultrasonic technology. The fingerprint scanning process is quite fast though not as fast as the other fingerprint scanners.

Currently, the Galaxy S20 Ultra already uses the Android 10 operating system and One UI interface 2.1. The latest interface from Samsung is more pleasing to the eye and has several useful features. Most bloatware can be removed from a cell phone to make storage more relieved.

A 5,000 mAh battery is used in this phone to support the performance and screen. For everyday use, the cellphone lasts 19 hours 34 minutes with Screen on Time 4 hours 58 minutes from 100% to 10% batteries. The battery life is arguably very satisfying and the cell phone can be used all day without the need to recharge the battery.

To further test the battery, we use the PC Mark application with settings for a screen brightness level of 50%, a 100% battery, a FHD + screen resolution, and a 60Hz refresh rate. The result Galaxy S20 Ultra won a score of 10 hours 19 minutes. If the refresh rate is set to 120Hz, the score is 8 hours 30 minutes.

Review of Galaxy S20 Ultra

This shows that there is a significant difference in battery power usage between the 120Hz and 60Hz refresh rates. The edges depend on each other’s preferences whether it is more concerned with a smoother screen animation or a more durable battery.

Charging the battery itself with the built-in charger only takes 1 hour 2 minutes from the 10% to 100% battery level. This is quite fast thanks to the use of fast charging 25W from the default charger Galaxy S20 Ultra. Actually the Galaxy S20 Ultra supports battery charging power up to 45W but this needs to buy a separate charger.


The Galaxy S20 Ultra uses a 4 rear camera configuration consisting of a 12MP Ultra Wide camera, a 108MP Wide-angle camera, a 48MP telephoto camera, and a DepthVision camera. For the front camera Samsung uses a 40MP resolution camera.


There are 2 most interesting points of the photographic ability of the Galaxy S20 Ultra camera that can produce photos with a resolution of 108MP and image enlargement up to 100x.

The main camera of the Galaxy S20 Ultra is able to produce good photos and good colors when we test for photos of plants and scenery. Although the main camera has a 108MP resolution, the camera will default to produce photos with a resolution of 12MP.

If desired, there is a feature to produce photos with a resolution of 108MP. 108MP photos can display clearer and brighter details than 12MP resolution photos. But the file size will multiply so wasteful storage.

It should be noted that the main camera of the Galaxy S20 Ultra has a shallow depth of field because of the 108MP resolution. This means that photos of objects at close range can produce photos that are somewhat blurry in some areas of the photo, especially those that are not the main focus of the camera.

The ultra wide camera on the Galaxy S20 Ultra even though the photo quality is not as good as the main camera but still able to take wide-angle photos well. Distortion on the side of the photo that is usually found in wide-angle mode will automatically be refined so it doesn’t look too strange.

The main strength of this camera phone lies in the ability to take photos with magnification up to 100x. Actually there are 3 methods of magnification in the Galaxy S20 Ultra, namely optical enlargement up to 4x, hybrid enlargement up to 10x, and digital enlargement up to 100x.


No doubt the Galaxy S20 Ultra is the most sophisticated Galaxy S phone Samsung has ever made. The ability to enlarge the picture is quite astonishing for a cellphone. Plus the battery life and performance are tough.

However, the price is arguably very expensive. And also the size is large and rather heavy so that it might not be suitable for some people especially those who have rather small hands.
