No computer or phone will work without an operating system. OS is not just a program, but a whole software shell between the user and the hardware components of the device. Sometimes this shell becomes outdated and needs to be updated. 20 years ago these updates could be made only by specialists, but today such an opportunity is available to ordinary users. Let's tell you how to update the Android OS on the phone on the example of "Samsung".

Check the current version

• 
  
• Open the "Settings" program. To do this, click on the gear icon in the application menu.
  
• Scroll down to "Phone Details" and open it.
  

• 
  
• Go to the "Software Information" subsection.
  

• 
  
• Find the items "Android version" and "Samsung One UI version". Note that before Android 9, a different Samsung Experience shell was used, so the settings may show information about it instead of One UI.
  

Done. The user can also find out service information about the OS using a third-party utility called AIDA64. Here is the link to install the utility.

Why you should update Android

Well, if the user has reached this point, it means that his phone is not updated to the latest version. We recommend to correct this misunderstanding. The fact is that the outdated version has many disadvantages, among which are:

• 
  
• The presence of security holes. Yes, they are also in the new versions of Samsung Galaxy, but so far few people know about them. As soon as a vulnerability becomes public, the developer releases a fix for it.
  
• Lack of new features. In some large-scale updates, unusual settings and built-in applications appear.
  
• Outdated interface. Developers, in order to amuse users, often redesign application icons and the interface of the system as a whole.
  

The second and third disadvantages are rather formal, because not all users like the abundance of functions and constant change of the interface.

It is worth noting that not all phones can be updated iphone emojis to download [x-android.click] the latest version.

Each model has its own support period, after the end of which the developers stop sending updates to the phone. This is due not only to marketing policy, but also to the fact that old phones may not be able to withstand new features.

How to do it

Updating the operating system is not only a simple, but also a flexible process. The developers of "Samsung" took into account the wishes of users and added to their phones several ways that are aimed at updating the firmware. Let's consider each of them.

Through FOTA.

Let's start, perhaps, with the classic method of updating, which is preferred by most users. FOTA - This is short for the term "Firmware Over-The-Air," which translates to "Firmware Over-The-Air Update." Why "over-the-air"? Because for this method, there is no need to connect to other devices with a wire. The device itself will download the system update package via mobile network or Wi-Fi. To perform over-the-air installation, follow the instructions below:

• 
  
• Charge your phone to 80%. You can also go up to 100%, but at least 80%.
  

• 
  
• Connect your phone to Wi-Fi. This is important, because downloading may use up all the mobile internet and interrupt the connection.
  

• 
  
• Check the free space on your phone. It is desirable to have 1.5 GB of free space in the memory.
  

• 
  
• Open the settings.
  

• 
  
• Scroll down the menu to "Software Update".
  

• 
  
• Open "Download and install" or "Update" or "Manually download update files". Depending on the model, the item name may vary.
  

• 
  
• Click on the "Download" button. It will only appear if there are suitable updates for this device.
  

In general, this method works in almost all cases. If it refused to download the latest version, it means that it is not supported by the device. To get around this limitation, you need to use other methods, which are described below. Keep in mind that installing an inappropriate Android version is always a risk that can lead to the phone not working.

Via Smart Switch

For this method, one phone will not be enough. The Smart Switch program is installed on a Windows or macOS computer. This means that you will have to find a computer and an adapter between the PC and the phone to work with it. In this instruction, the author will use the Windows version, which is installed via this link. So, the algorithm of flashing via Smart Switch:

• 
  
• Connect the phone to the computer via USB.
  

• 
  
• Wait for PC to recognize the phone.
  
• Install and run the program from the subheading.
  

• 
  
• Wait for the update search to complete.
  
• If a suitable version is available, click "Update".
  

• 
  
• Do not disconnect the phone from the computer until the new firmware download procedure is complete.
  

Note that if two phones are connected to the computer, the program may get confused. That's why it is recommended to use only one device at a time.

Samsung PC Kies

This utility is similar to the previous program in many ways. It is also an official program. Just the programs above are usually used to transfer files between two devices, while PC Kies is designed specifically for downloading files from PC to phone. These utilities even have similar setup instructions, so we won't repeat it twice. By the way, while testing the software, the author encountered a problem - the program did not want to run on Windows 10. The problem was solved by running it in compatibility mode.

Recovery mode

Recovery is a classic method that will work for any phone, not only for models from the Samsung Galaxy series. It is worth noting that unlike the analogs above, recovery is a powerful tool that allows you to install any version of Android and shell, regardless of the phone model. But at the same time, recovery is also a complex tool, the improper use of which can lead to the breakdown of the gadget.

In general, if you are a beginner, it is recommended to follow the instructions carefully, or entrust this matter to experts. Flashing algorithm:

• 
  
• Download the ADB AppControl utility from the official website. It is a convenient graphical tool for working with ADB. Usually specialists use the console version, but for beginners the graphical interface will do just as well.
  

• 
  
• Connect your phone to the computer.
  

• 
  
• Enable debugging mode on your smartphone. Read about how to do it here.
  

• 
  
• Go to the "Tools" section and click on the "Reboot" button.
  

• 
  
• Select "Recovery" from the drop-down menu.
  
• Now on the phone, use the power buttons to go down to "Apply update from ADB". Press the power button to confirm the action.
  

• 
  
• Now download the desired firmware from the 4PDA website. Versions for Samsung can be found here.
  

• 
  
• Upload the downloaded archive to the folder with the program.
  
• Open the program and go to the "Console" section.
  

• 
  
• Type the command "adb sideload file.zip" and press enter. Instead of file.zip, enter the name of the downloaded file.
  

• 
  
• Wait for the procedure to complete.
  
• Confirm the reboot of the device.
  

If this method didn't work, try specifying "bootloader" in step five. In this case, the sixth step should be skipped.

Possible problems

Alas, none of the above methods works perfectly. Errors, freezes and failures are sometimes unavoidable. Fortunately, most problems can be solved in a couple of clicks, the main thing is to identify the cause. Below are collected a few frequent problems faced by users.

Firmware does not boot to the end

This problem most often concerns installation with the help of third-party programs (the second, third and fourth way). The fact is that these utilities can not calculate in advance the amount of free space for downloading the update. If this space is not enough, the phone will hang and will not be able to update to the end. The user will only see the download bar stuck in one place. In this case, it is recommended to perform a factory reset, or install a lighter firmware. About how to do a reset, is written in detail in this material.

Alas, in some special cases, the system files (these are pre-installed programs responsible for starting the device and its performance) are also damaged, because of which the phone stops responding to any actions. In this case, it will have to hand it over to the service center, so that the specialists themselves re-flashed the gadget.

Internal failures after the update

The phone hangs, performs arbitrary actions, does not obey the user, and applications live their own life - these and other failures can occur after an unsuccessful update of the gadget. Most often such failures occur due to overly demanding updates or broken files. To solve the problem, install another firmware through recovery.

In this case, a factory reset will not help, because the firmware has replaced all the system files. We hope that the instructions in the material helped in solving the problem. If not, then feel free to write about the problem in the comments. Our moderators will be happy to help.
