Samsung Galaxy S20 Review: Everything you need to know

Samsung Galaxy S20 Review

Samsung has recently launched a top-end flagship – the Samsung Galaxy S20 – a comparably diminutive Galaxy S series that most of us think it is the best ever Android phone a person can get at the moment since it’s a refreshing change of pace. With their latest flagship, Samsung was a little bit more ambitious in the launch of a souped-up conventional pair of flagships. You will find that there are only a few Android devices that can match or even get close to look as good or more advanced as the Samsung Galaxy S20.

Earlier before Samsung launched the smartphone we had the internet swamped with different rumors and leaks of what we should expect to be offered. But what is the real deal from Samsung after the launch of the Samsung Galaxy S20? Here is an in-depth review of the Samsung Galaxy S20.

In-built eSIM

The use of an eSIM is a new technology that has not become prevalent with many smartphone users. Samsung Galaxy Fold was the first Galaxy phone to incorporate this technology and now we have Samsung Galaxy S20 using the new technology. Other smartphone devices that already use this technology include iPhone 11, Motorola Razr and Pixel 4, and the Galaxy Z Flip – launched together with Galaxy S20.

All you need to know about eSIM

SIM cards are vital constituents that connect a cellular network to your phone, and thus you can be able to send texts as well as make calls through a phone number. The common SIM cards are mainly plastic chips that are removable from the phone. Advancement in technology has brought the eSIM. ESIM serves the same purpose as the plastic chip SIM card with the only difference being that eSIM is among the internal components of the phone – or rather it is not removable.

What happens is that the eSIM (embedded subscriber identity module) the embedded electronic chip can be programmed and at the same time reprogrammed helping you to switch or hop between carriers without having to get a new SIM card.


ESIM technology has some of its benefits which include:

  • The eradication of the removable SIM tray means that there is more space where phone manufacturers can adjust and make bigger batteries. Space is also usable for additional cameras.
  • Since one can hop from one service carrier to another easily, then there is no need for purchasing different SIM cards for the different carriers. It just takes a few taps on your smartphone and you’re already using a different service carrier.

The only shortcoming is that we all know that the SIM card tray has an extra microSD card slot meaning if we are eradicating the tray then there will be no space for adding additional storage.

For the past couple of years, there hasn’t been any huge redesign in Samsung’s S series. The S20 device looks much like the other handsets. Just like the S10 series, the front of Galaxy S20 is an OLED screen display and the back is a glass composed of smattering curves.

The camera layout at the back is distinctive – it’s more intrusive. The step-back with the Galaxy S20 is the lack of uniqueness in their color options if compared to the iPhone 11 Pro and Google Pixel 4.

Samsung further opted to omit the 3.5mm port for the headphones on the Galaxy S20. We earlier saw OnePlus and Apple ditch the notch and now the S series looks like they have adapted the norm. Now the Samsung Galaxy Buds – the wireless headphones – will become more popular.

Samsung flagships are considered to have some of the best displays in the smartphone world of smartphones. The Galaxy S20 flagship has added a 120Hz refresh rate to its 6.2-inch slightly curved OLED panel display. It means that these displays can refresh 120 times in a second a rate that is twice higher than the 2019 flagships whose rate is 60 times a second. The phone is therefore faster. The battery consumption is rather high and you might, therefore, find that to activate the 120Hz display you must set it yourself.

Samsung has made some huge advancements in their Galaxy S20 flagship from the S10 series. Although the main cameral remains at 12MP, its aperture is f1/8. The S20 further has increased its pixels to 1.8 microns from 1.4 microns. The camera can, therefore, capture more light and more detail. The telephoto camera has been improved from 12MP to 64MP.

In video recording, the S20 has broken the ground as it has introduced an 8K video recording and up to 60 degrees (anti-roll correction) as a part of a stabilization feature – Samsung’s Super Steady.


Two different chipsets power the Galaxy S20. The United States customers get the Qualcomm’s top-end Snapdragon 865 chipset. Exynos 990 is offered to people from the rest parts of the world. The two chipsets have done so well in loading applications and playing games. They load quickly.

5G connectivity

In 2018 rumors speculated that we would get 5G phones in 2019 and in 2019 only less than 1% of the phones produced and distributed were 5G. S20 is fully a 5G smartphone. The download speeds of the 5G network hover up to 200Mbps which is 6 times greater than the 4G network.

Battery Life

One thing we should have in mind is that since this handset is a 5G, battery consumption is very high. Samsung powered its Galaxy S20 with a 4000mAh battery which is an increase from S10’s 3400mAh capacity. The S20 further incorporates the fast charging and a 15W wireless charging system but slower than the wired charging system.

The S20 has the reverse charging feature and therefore if you have a gadget that supports Qi charging, you can then reverse charge the device with the S20 device.


In the UK, the US and Australia the phone is going at £899 /$999 /AU$1,499 for the 12GB RAM and 128GB storage. The 4G 128GB storage and 8GB of RAM version go for £799 in the UK $AU$1,349 in the Australia and AED 3,199 in the United Arab Emirates.

Wrap up!

If you want to buy the best Android device for yourself, then I would suggest you go for this device. It is the best and the biggest selling flagship at the moment. You should grab one now that Coronavirus will affect the production of other gadgets such as the Note and the iPhone.
