This Galaxy S20 guide explains what Galaxy S20 dark mode is, how to use and customize the dark mode on Galaxy S20, and how to force all apps to use dark mode on Galaxy S20.

Galaxy S20 dark mode works identically on Galaxy S20, S20+, and S20 Ultra. So this guide applies to all these three Galaxy S20 phones.

What is Galaxy S20 dark mode?

Galaxy S20 dark mode turns on a dark theme at the system level to alleviate eye strain, especially under low-light conditions. In the past, it was called night mode sometimes.

To avoid confusions with the camera night mode, Samsung followed the Android convention of the dark theme and named it officially as the dark mode since Android 10 update.

So, essentially, Galaxy S20 dark mode is the dark theme in other Android phones noticeable improvements.

The dark theme will try to use dark (black or grey) background and white text. This usually makes your eyes more comfortable when staring at the screen, especially when the light condition is not good.

Individual app developers may choose to implement the Android dark theme, or ignore it, or implement their own dark theme.  So, by default, some apps may ignore the dark mode. In Android 10, you can force all apps to use the Galaxy S20 dark mode (read on).

One beneficial side-effect of applying Galaxy S20 dark mode is noticeable power saving (without changing Galaxy S20 power mode).  Because Galaxy S20 uses super AMOLED. The black pixels consume almost no power. So, when you switch to the dark background, the screen will utilize less power. For most owners, power saving is noticeable, and it is helpful to extend the battery lifespan slightly.

For most Galaxy S20 owners, there are three benefits of turning on the dark mode on Galaxy S20:

  1. Alleviate eye strain.
  2. Save battery.
  3. Aesthetic (depending on individual owners). Some users prefer a white (light) background, and others may prefer the black (dark) background.

You can enable or disable Galaxy S20 dark mode at any time manually, or use it automatically based on your schedule.

Better cameras: the most appealing new features of Galaxy S20

The No.1 reason you may consider to choose or upgrade to Galaxy S20 is the camera.

If you are happy with the camera on your current phone, there is NO reason to change or upgrade to Galaxy S20. Period.

As explained in the differences among Galaxy S20, S20+, and S20 Ultra, the cameras in Galaxy S20 and S20+ are similar. What differs Galaxy S20 camera from competitors is the camera on Galaxy S20 Ultra.

Front camera

For the front camera, Galaxy S20 and S20+ share the identical 10MP camera sensor with last year’s Galaxy Note 10 and Galaxy Note 10+.  They are only slightly better than the front cameras on Galaxy S10+, Galaxy S10, and Galaxy S10e.

But S20 Ultra is a different story.

The 40MP front camera on Galaxy S20 Ultra is a significant improvement compared to previous models. In low-light conditions, Galaxy S20 Ultra can combine 4 pixels into one and delivers better quality 10MP photos.

Rear cameras

Top 10 differences among Galaxy S20, S20+, and S20 Ultra

differences among Galaxy S20, S20+, and S20 UltraSamsung released 3 models of Galaxy S20. So what are the major differences among Galaxy S20, S20+, and S20 Ultra?

This Galaxy S20 guide explains the top 10 differences of these 3 models to help you choose the correct Galaxy S20 model for your needs. The major differences among Galaxy S20, S20+, and S20 ultra include screen size, price, rear camera system, front camera, battery capacity, RAM, storage, colour options, weight and charging speed.

Please note, in some regions, the configuration options (RAM, storage, colour, 5G, LTE) may be limited. But software features are all identical in these three Galaxy S20 phones.

Screen Size

All of the three phones share the same screen resolution (WQHD+, 3200×1440) and display technology (Dynamic AMOLED 2X).

And all of the three phones support 120Hz refresh rate (at 1080p resolution) as explained in this page. FYI, most of the mainstream TVs, smartphones, PC monitors, laptop screens have a refresh rate of 60Hz.

But the size of the screen differs on these 3 phones:

  • Galaxy S20: 6.2″
  • Galaxy S20+: 6.7″
  • Galaxy S20 Ultra: 6.9″

The size difference between Galaxy S20 and the other two big brothers is obvious.  Between Galaxy S20+ and S20 Ultra, the difference is not so obvious.

In addition to the size, the curvature of the edge of the screen also differs noticeably among these 3 phones. Galaxy S20 screen is the flattest. Galaxy S20 Ultra has the sharpest curvature.

Please note,  the aspect ratio of the screen on Galaxy S20, S20+, and S20 Ultra is 20:9. So, Galaxy S20 looks narrower than Galaxy S10 and Galaxy Note 10 (19:9), and therefore the 6.9″ Galaxy S20 Ultra is narrower than the 6.8″ Galaxy Note 10+ (76mm vs 77.2mm in width).


What is common in the price of the Galaxy S20, S20+, and S20 Ultra is expensive.

Among these 3 expensive Galaxy S20 models, Galaxy S20 Ultra is the most expensive starting at $1399 (with the base configuration).

Galaxy S20 starts at $999, and S20+ at $1199. These are for base (aka, minimum) configurations only, again.

This is a huge jump from the Galaxy S10 series.

It seems  Samsung cannot make the best Android phone. But they can make the most expensive mainstream Android phones.

Actually, Galaxy S20 is more expensive than the latest iPhone 11 Pro, which starts at $999 only.

Surely, this price is not sustainable.  … Read the rest
