Samsung Galaxy Devices

Samsung Galaxy is a series of high-end smartphones that are developed by Samsung Electronics. Along with smartphones, the Galaxy series also consists of Galaxy Tablets, Galaxy Note, and Smartwatches. The product line has become one of the biggest in the world owing to the brand name. The Galaxy phones have one of the most convenient and customizable UI on Android called OneUI. OneUI has previously been known as TouchWiz or Samsung Experience earlier. OneUI does come with a large number of stock apps that are pre-installed on the smartphone. Apps like Samsung Health, Samsung Kids, and several more are considered as nothing more than bloatware. On the other hand, apps like Samsung Pay and Galaxy Store have had a positive reception from the users. Although getting rid of these stock apps and bloatware is not very hard thankfully because of the Android OS.

Being on the higher-end of the market, the Galaxy product line finds itself competing with the Apple iPhones. Along with Android, Galaxy has also tried out the Windows 10 OS on its GalaxyTab Pro S.

Galaxy in the past few years has been experimenting with its hardware designs. With the S8, they removed the humongous Home button. The button was a pretty unique feature of Galaxy devices and helped in differentiating it from other Android smartphones. In 2019, Samsung introduced the Z series which showed a large amount of innovation with its foldable design. Although the first Galaxy Z Fold, released in 2019, was met with criticism for its faulty hardware. Samsung released the Z Fold 2 in 2020 which solved several critical problems that were present in its first iteration.

At the time of writing, the Galaxy product line has sold more than 2.5 Billion units.

Wireless Fidelity (Wi-Fi)

In today’s world WiFi is not a luxury but more well put, it’s a necessity. Gone are the days when WiFi was just used to access the Internet using your router. (Fun fact, my router started acting up while writing this exact sentence). Nowadays, WiFi is used for multiple purposes such as interacting with your electrical appliances, connecting to multiple devices over the local network, file sharing, and several more. Learn how To Fix WiFi authentication error.

It’s a service that is taken for granted to be present on a new smartphone or a PC. Even though useful, WiFi does have its flaws, mainly Range and Security. WiFi performance is inversely proportional to the range, meaning the further away you are the worse the performance gets. During its initial years, WiFi used Wired Equivalent Privacy (WEP) encryption which proved to be easily breakable. In 2003, WPA and WPA2 (Wi-Fi Protected Access) was rolled out providing more security to wireless networks. In June 2020, a more secure version was rolled out known as WPA3.

WiFi Calling

Cellular networks are not very reliable. If in one room you are getting full bars it is very much possible that in another you will get a No Service SOS message. This is when you will call WiFi Calling a lifesaving feature. It enables you to make voice calls over the WiFi network free of any additional cost. This is especially useful if your cellular network doesn’t provide good audio quality during voice calls. The availability of this feature does depend on the availability of the HD Voice feature or VoltE. To check if your smartphone has this feature you can check this list. In this article, I will go through how to access the WiFi calling setting and how to avail of the feature itself.

Enable/Disable WiFi Calling

  1. Go to the Settings on your Galaxy phone.
  2. On Galaxy S5 or below, go Under Wireless and Networks select More Settings.
  3. On newer versions of Galaxy devices, the option is available in the Setting menu itself.
  4. Select “Wi-Fi Calling”.
  5. You can use the toggle button to turn it On/Off.
  6. You can also change the preference for voice calls from this menu. Setting it to “Wi-Fi” will prefer WiFi Calling over Cellular network and vice-versa

If you don’t see a Wi-Fi Calling setting, there’s a good chance that your smartphone doesn’t support it.

That’s it. You are now set to make voice calls over your WiFi Network. Based on your preference you will be able to make WiFi calls when required. WiFi Calling uses your already active voice plans and data from your WiFi to make calls. Learn more deeply about how to turn off wifi calling.
