Updating the operating system Android is a key process that affects the performance, security and functionality of your smartphone. However, many users are faced with questions: how exactly does the update take place, how long does it take, and what to do if something goes wrong? In this article, we will analyze all the stages - from preparing the device to completing the installation, and also talk about nuances that will help avoid common mistakes.

It is important to understand that the update process may differ depending on smartphone manufacturer (Samsung, Xiaomi, Google Pixel etc.), version Android and even region. For example, device owners Samsung Galaxy often receive updates later than users Pixeldue to additional checks by the manufacturer. We will look at universal steps that are relevant for most devices, and also point out features that are worth considering.

1. How to check if an update is available

Before you start the update, make sure that it is actually available for your device. To do this, go to Settings → System → System update (on some devices the path may differ, for example, Settings → About device → Software update). The system will automatically check for new versions.

If the update is not found, this may mean:

  • 🔄 Your device has not yet received the update (the manufacturer has not released it for your model or region).
  • ⏳ The update is being released in stages, and your smartphone will be included in the next wave of distribution.
  • 🚫 The device is no longer supported (relevant for older models, for example, Samsung Galaxy S8 or Xiaomi Redmi Note 5).

On some devices (for example, Google Pixel) you can manually register in the beta testing app Androidto receive updates before the official release. However, this is associated with the risks of unstable system operation.

2. Preparing your smartphone for updating

Before starting the update, follow several important steps to minimize risks:

  1. Create a backup copy of your data. Updating rarely leads to loss of files, but it’s better to play it safe. Use Settings → Google → Backup or third-party applications like Titanium Backup (requires root access).
  2. Charge the battery to at least 50%. If the charge is lower, the system may block the start of the update.
  3. Connect to a stable Wi-Fi network. Updates range from 500 MB to 2–3 GB, and download via mobile data can be expensive.
  4. Free up space in memory. Free space is required to install the update (usually 1–3 GBDelete unnecessary files or transfer them to the card). memory.

Battery charge > 50%|Connected to Wi-Fi|Data backup|Free space > 2 GB|Closed background applications-->

If you are using custom ROM (for example, LineageOS), the update process will be different. In this case, you will need to download the firmware manually and install it via recovery (for example, TWRP).

⚠️ Attention: On devices with an unlocked bootloader (bootloader), automatic updating may reset the settings or lead to errors. update, check whether your custom firmware supports OTA updates.

3. Stages of installing the update

When the preparation is completed, you can begin the installation. The process usually takes place in several stages:

  1. Downloading the update file. The system will download the update package (the weight depends on the version). At this stage, you can continue to use your smartphone, but the download speed may decrease.
  2. Preparing for installation. The device will reboot and begin unpacking the files. You can no longer interrupt the process!
  3. Update installation. The logo will appear on the screen Android and progress indicator. Installation time - from 5 to 30 minutes depending on the model.
  4. Optimization of applications. After rebooting, the system can further configure applications (this is normal, do not turn off the device).

On some devices (for example, Samsung or OnePlus), network settings (Wi-Fi, mobile data) are reset after the update. Write down passwords in advance or use the function Google Smart Lock to save them.

Stage Time Can I interrupt? What to do if frozen?
Downloading file 5–60 min Yes (but you will have to start over) Reboot the device and try again
Unpacking 2–5 minutes No Wait 10–15 minutes, if there is no progress, contact the service
Installation 10–30 minutes No Forced reboot can damage the system
Optimization 5–15 min No Wait for completion or reset the cache to recovery
What to do if the update is stuck on the Android logo?

If the device hangs on the logo for more than 30 minutes:

1. Try to force reboot it (press Power + Volume Down for 10-15 seconds).

2. If that doesn’t help, go to recovery (usually Power + Volume Up) and select Wipe cache partition.

3. In extreme cases, flashing may be required via Odín (for Samsung) or Fastboot (for other brands).

4. Possible errors and their solutions

Even with proper preparation, the update may fail. Let's look at the most common problems and ways to fix them:

  • 🔌 Download error (Error downloading update).
    Causes: unstable Internet connection, insufficient memory, server failures Google.
    Solution: reconnect. to Wi-Fi, free up space or try later.
  • 🔄 Cyclic reboot (bootloop).
    Reason: conflict with custom recovery or damaged system files.
    Solution: reset the settings to factory settings or reflash the device.
  • 📱 The device does not turn on after the update.
    Reasons: critical installation error, firmware incompatibility.
    Solution: try booting into Safe Mode (press Power when turning on) or contact the service.

If the error is due to insufficient space, try:

  1. Delete application cache in Settings → Storage → Cache data.
  2. Move photos and videos to a memory card or to the cloud.
  3. Delete unused applications (especially heavy games).
⚠️ Attention: On some devices Xiaomi and Realme after an unsuccessful update, the bootloader may be locked (bootloader). In this case, you will need official firmware via Mi Flash Tool or Realme Flash Tool.

5. Features of the update on different brands

Smartphone manufacturers often modify the update process to suit their branded shells (One UI, MIUI, ColorOS etc.) Let's look at the key differences:

Brand Shell Update features Average waiting time for updates
Google Pixel Stock Android Receive updates first, support for 5+ years 1–2 weeks after release
Samsung One UI Additional security checks, updates are released in stages 1–3 months
Xiaomi MIUI Frequent weekly updates for beta testers, stable versions - once every 2-3 months 2-4 weeks
OnePlus OxygenOS / ColorOS Fast updates for flagships, budget models are updated less frequently 2-6 weeks

For example, owners Samsung Galaxy often face update delays due to additional tests by telecom operators (especially in the US and Europe). And users Xiaomi can choose between a stable and beta version MIUI, but the second may contain bugs.

💡

If your device Samsung does not receive the update, check it in the application Smart Switch on your PC. Sometimes updates are only available through a computer.

If after the update there were slowdowns or overheating, try:

  1. Clear cache in Settings → Storage → Cache data.
  2. Disable animation in Developer settings (enabled by tapping on Build number in About the device).
  3. Reset settings to factory settings (if the problems are critical).
💡

After major updates (for example, from Android 12 to 13), some applications may not work correctly Developers usually release patches within 1-2. weeks.

7. How to roll back an update if something went wrong

If after the update the smartphone begins to work worse (for example, it discharges faster or overheats), you can try to roll back to the previous version, however, this is a complex process, and it is not always possible without losing data.

Methods. rollback:

  • 🔙 Through the factory firmware. Download the official firmware for your model from the manufacturer’s website and install it via recovery or Fastboot.
  • 📦 Through a backup. If you made a backup in TWRP or friend custom recovery, restore it.

  • 🔌 Use a PC to update. Some brands (e.g. Samsung or LG) allow you to install firmware through official utilities (Smart Switch, LG Bridge).
  • 📡 Change the region. On some devices (for example, Xiaomi) you can change the region in the settings and get the update earlier. However, this may break warranty.

For devices Samsung you can use a proprietary application Smart Switch on a PC - it sometimes finds updates that are not yet available over the air (OTA).

💡

Manufacturers often release updates first for flagship models, and then for budget ones. If you have a mid-range smartphone, you will have to wait.
