Samsung Galaxy A50 remains one of the most popular mid-class smartphones even 5 years after release. However, with the release of new versions Android and One UI owners are faced with the question: how to safely update the firmware so that the phone works faster and more stable? In this article, we will look at all the current update methods - from automatic through settings to manual using Odin.

It is important to understand that the process depends on the current firmware version, the region of purchase of the device, and even the telecom operator. For example, models for Russia (SM-A505FN) and Europe (SM-A505F) receive updates at different times. We will look at universal methods that are suitable for most options Galaxy A50.

1. Preparing your phone for the update

Before you begin the update, there are a few critical steps you need to take. Neglecting them can lead to data loss, device freezing or even "bricking" (complete inoperability).

First, check battery charge. The level should not be lower 50%, but better - 80-100%. Updating the firmware takes between 10 and 40 minutes, and if the phone dies during the process, the consequences can be unpredictable. Secondly, free up at least 3-5 GB memory: new versions Android i One UI weigh about 1.5-2.5 GB, but unpacking and installation require additional space.

  • 🔋 Battery charge: minimum 50%, optimal 80%+
  • 📱 Free memory: 3 GB and more (check in Settings → Device care → Memory)
  • 🌐 Stable Internet connection: Wi-Fi (updating via mobile data may lead to additional tariffs)
  • 🔐 Backup: save contacts, photos and applications in Samsung Cloud or Google Drive
⚠️ Attention: If your Galaxy A50 was purchased from a telecom operator (for example, MTS, Beeline, MegaFon), the update may be blocked until the provider approves. In this case, use the method with Smart Switch or Odin.

We also recommend disabling antivirus apps and VPN during the update - they may interrupt downloading files. If you are using a MicroSDcard, remove it: sometimes the system tries to write. temporary files to a removable drive, which leads to crashes.

2. Method 1: Automatic update through settings

The simplest and safest method is over-the-air update (OTAIt is suitable for most users, as it does not require additional ones). apps or technical knowledge. However, it has a limitation: you will only receive the version of firmware that is officially released Samsung for your region.

To check for updates, go to: Settings → Software update → Download and installation.

The system will automatically check for available ones updates. If there are any, a button will appear Download. After downloading, the phone will offer to install the firmware - agree and wait for the reboot.

Step Action Note
1 Open Settings Gear icon on the main screen or in the application menu
2 Go to Software update In some versions of One UI, the item may called Software update
3 Click Download and installation If the button is inactive, there are no updates
4 Confirm installation The phone will reboot 1-2 times

If the button Download and installation is missing or the server is not responding, try the following:

  • 🔄 Reboot the phone and try again
  • 📶 Connect to another Wi-Fi network (sometimes corporate networks block updates)
  • 🕒 Try later: Samsung servers may be overloaded
⚠️ Attention: If after the update the phone starts to slow down, reset the cache in Recovery Mode (press Power + Volume up + Bixby at switched off phone, then select Wipe cache partition). This will not delete your data, but will clear temporary files.

After a successful update, the phone may take a long time to boot (up to 15 minutes) - this is normal. If the screen is frozen on the logo Samsung more than 20 minutes, perform reset (Power + Volume up + Bixbythen Wipe data/factory reset).

What to do if Odin does not see telephone?

6. How to roll back an update on Samsung Galaxy A50

Sometimes new firmware versions work worse than previous ones: bugs appear, performance decreases, or necessary functions disappear. In such cases, users want return to the old version of Android. However Samsung does not officially support rollback, so the process requires caution.

To rollback you will need:

If after a rollback the phone is unstable, try:

  • 🔄 Repeat the firmware with a different version of Odin. (for example, v3.13.1 instead of v3.14.4).
  • 📥 Install the firmware via Smart Switch (if the required version is available).
  • 🛠️ Reset via Recovery Mode (Wipe data/factory reset).

7. How to check success updates

After installing the new firmware, you need to make sure that everything went correctly. To do this:
