Have you noticed that on your smartphone Android the time is behind, in a hurry, or even shows the wrong date? This problem occurs more often than it seems - from budget Xiaomi Redmi to flagship Samsung Galaxy. The wrong time is not just annoying: it throws off notifications, interferes with the operation of applications (for example, Google Authenticator or banking services), and sometimes even blocks access to some functions.

In this article we will analyze 7 main reasonswhy Android shows the wrong time - from banal user errors to system errors failures. You'll learn how to diagnose the problem, fix it manually or automatically, and what to do if neither method works. All instructions are suitable for devices based on Android 10–14 (including One UI, MIUI, ColorOS and other shells).

1. Disabled automatic time synchronization

The most common reason is deactivated automatic time update setting. By default Android synchronizes the date and time with servers Google or the telecom operator, but after a software update, reset or manual intervention, this function may be disabled.

How to check:

  • 📱 Open Settings → System → Date and time.
  • ⏰ Make sure the switches are on "Auto-detection of date and time" and "Auto-detection of time zone" active (slider in position "On.").
  • 🌐 If There is no option, your device may use an alternative synchronization source (for example, the operator’s network).

If automatic synchronization is enabled, but the time is still lost, the problem may lie in unstable internet connection or blocking of time servers. Try switching from Wi-Fi to mobile data (or vice versa) and wait for the update.

2. Incorrect time zone

An error in the time zone is the only reason why time on Android can “run away” several hours forward or backward, even if minutes and seconds are shown correctly. This often happens after traveling, changing a SIM card or manually changing settings.

How to fix:

  1. Go to Settings → System → Date and time.
  2. Disable "Auto-detection of time zone" (if enabled).
  3. Manually select your region from the list (for example, "Moscow, GMT+3").
  4. Turn automatic detection back on and reboot the device.

If your city is not in the list, select the nearest major one (for example, St. Petersburg instead of Vyborg). Also check if you have an application installed for geolocation changes (for example, Fake GPS) - it may confuse the time zone.

💡

On some firmware (for example MIUI), the time zone may be confused due to a bug in the "Double Clock" function. Disable it in the time settings if you do not use it.

3. Failure of NTP servers synchronizes time through the Network Time Protocol using servers or alternative sources. If the server is unavailable (for example, due to blocking by the provider or problems with the Internet), the device may “freeze” at the wrong time.

Android synchronizes time via protocol NTP (Network Time Protocol) using servers Google (time.google.com) or alternative sources. If the server is unavailable (for example, due to blocking by the ISP or problems with the Internet), the device may freeze at the wrong time.

How to check the functionality of NTP:

  • 🔄 Restart your smartphone - sometimes this resets the time cache.
  • 📡 Connect to another network (Wi-Fi or mobile data).
  • 🛠️ Install the application ClockSync (from Google Play) and manually update the time through it.

If the problem persists, try change NTP server:

  1. Download the application NTP Sync or Time Sync.
  2. In the settings, specify an alternative server, for example: 
    pool.ntp.org

    ru.pool.ntp.org
    

    time.cloudflare.com

  3. Perform forced synchronization.
What is NTP and why is it important?

NTP (Network Time Protocol) is a standard for synchronizing time over a network. It is used not only in smartphones, but also in servers, routers and even ATMs. NTP accuracy reaches ±10 milliseconds, which is critical for the operation of SSL certificates, transactions and geolocation services. If NTP is disabled or blocked, the device may use an internal crystal oscillator, which over time "goes away" for a few seconds or minutes.

4. Battery problems or hardware malfunctions

If the time is off only after shutdown or reboot (for example, it is 5-10 minutes behind), the culprit may be dead battery or faulty quartz resonator (it is responsible for counting the time when it is turned off). This is typical for older devices (for example Samsung Galaxy S7 or Xiaomi Mi A1), where the battery has lost capacity.

Signs of a hardware problem:

  • ⚡ The time is lost even when automatic synchronization is turned on.
  • 🔋 The phone discharges quickly (in less than 4-5 hours).
  • 🔄 After reboot the date is reset to January 1, 1970 (a typical symptom of an RTC chip failure).

Solutions:

  • 🔧 Replace the battery (cost - from 1,000 to 3,000 rubles per depending on the model).
  • 🛠️ Contact a service center to diagnose the motherboard (you may need to resolder the quartz resonator).
  • 📱 If the device is old, consider buying a new one - repairs may be more expensive.
💡

If after replacing the battery the problem remains, it is not the battery that is to blame, but a hardware fault fees. In this case, independent repair is not recommended - soldering equipment and experience are required.

5. Conflict after firmware update

Updates Android sometimes lead to failures in system services, including time synchronization. This is especially true for devices with custom firmware (LineageOS, Pixel Experience) or after a manual update via ADB/Fastboot.

How to fix:

  1. Reset the time settings to factory settings: 
    Settings → System → Reset → Reset date and time settings
  2. If did not help, do soft reset (without data loss): 
    Settings → System → Reset → Reset all settings
  3. For custom firmware, reflash the module NTP via Magisk or TWRP.

If the failure occurred after major update (for example, from Android 12 to 13), check the support forums for your model - perhaps this is a known bug for which it is already released a patch

Check the firmware version in Settings → About phone

Make sure automatic time synchronization is enabled

Reboot your device

Update applications via Google Play

6. The influence of third-party applications

Some apps may block access to time servers or change system settings. Most often, the culprits:

  • 🔒 VPN applications (for example, NordVPN, ProtonVPN) - can redirect NTP requests.
  • 🛡️ Antiviruses (Kaspersky, Avast) - sometimes block "suspicious" connections.
  • 🎮 Cheat utilities for games (for example, GameGuardian) - change the system time to deceive servers.
  • 📱 Launchers with a clock widget (for example, Nova Launcher) - may conflict with standard settings.

How to find the culprit:

  1. Launch the device in Safe Mode (hold the power button → "Safe Mode").
  2. Check if the time is correct. If yes, the problem is in third-party software.
  3. Uninstall recently installed applications one by one, starting with VPN and antiviruses.

If the culprit is found, but you don’t want to remove it, check the app settings - perhaps there is an option "Ignore system time" or "Disable NTP synchronization".

7. Problems with the SIM card or telecom operator

Some operators (for example, Tele2 or Iota) transmit time through their network (NITZ — Network Identity and Time Zone). If this feature does not work correctly, the device may receive incorrect data. Problems also arise with:

  • 📶 Roaming (especially when crossing borders with a large time shift).
  • 🔄 Changing the SIM card without rebooting the phone.
  • 📵 Using virtual operators (for example, SberMobil Tinkoff Mobile, SberMobil).

Solutions:

Problem Action
Time is out of order roaming Disable "Auto-detect time zone" and select it manually.
Incorrect time after changing SIM Reboot the phone or turn on/off "Airplane mode".
The operator is transmitting the wrong time Disable "Use time network" in the date and time settings.
Problems with the virtual operator Install the operator application (for example, My Tele2) and update the settings.

If the problem persists, contact the operator's support - there may be technical work on their side or a failure in data transmission NITZ.

💡

Virtual operators (MVNO) often skimp on infrastructure, so their time servers may be unstable. In this case, it is better to disable synchronization via the network and use only NTP.

What to do if nothing helps?

If you have tried all the methods, but the time on Android still gets lost, radical measures remain:

  1. Factory reset settings:

    This will delete all data, but return the device to its original state. First make a backup via Settings → Google → Backup.

  2. Flashing via Fastboot or Recovery:

    If the failure is caused by damage to system files, a clean installation of the firmware will help. Look for instructions on the forums 4PDA or XDA Developers for your model.

  3. Contacting a service center:

    If the time is lost due to a hardware fault (for example, a damaged chip RTC), you can’t do without repairs. For devices under warranty, this is free.

Before resetting the settings, check whether the incorrect time is due to with root access or custom kernels. If you installed Magisk, Xposed or modified software, try rolling back the changes.

💡

Before resetting to factory settings, write down the IMEI of the phone (dial *#06#). In rare cases, after a reset, it may be reset and will have to be restored.

FAQ: Frequently asked questions about time on Android

❓ Why is the time on the phone different from the time on the computer?

Computers (especially on Windows) are often synchronized with servers Microsoft (time.windows.com), and Android - with Google. The difference is usually 1-2 seconds, but due to network delays it can reach several minutes. To unify the time, set up synchronization on your PC with time.google.com.

❓ Can a virus change the time on Android?

Yes, some viruses (for example, Trojan.AndroidOS.Loapi) change system settings, including the time, in order to bypass the protection of banking applications or hide their activity. If you suspect an infection, scan your device through Malwarebytes or Dr.Web and reset the time settings.

❓ Why does the time get lost even more after replacing the battery?

This is a sign poor quality battery or damage to the contacts on the motherboard. Cheap batteries may not provide sufficient current to power the RTC-chip (responsible for the time in the off state). Also check if the battery cable is connected correctly - sometimes it comes off when replaced.

❓ How to check if NTP is working on my phone?

Install the application Ping & Net and perform a ping request k time.google.com. If packets do not arrive or the response time exceeds 500 ms, the server is blocked. You can also use the command in ADB: 

adb shell ping time.google.com

The absence of a response will confirm the problem with NTP.

❓ Why is the time displayed incorrectly in some games, but normally in the system?

Games (for example, Clash of Clans or Pokémon GO) can use their own time servers to protect against cheats. If the time in the game is wrong, but the system is not, update the game or reinstall it. Also check if the mode is enabled in the game settings "Offline".

If your problem is not described in the article, check the details: phone model, version Android, when exactly the time is lost (after a reboot, while roaming, etc.). This will help narrow down the range of possible causes.
