How to change the time on a Samsung Android phone: all methods

A lost clock on a smartphone is a problem that almost every user has encountered. Samsung Galaxy. The wrong time not only makes it difficult to navigate your schedule, but can also disrupt the operation of applications, notification synchronization, and even the alarm function. Fortunately, you can fix this in a few minutes, and in most cases you won’t need to reboot the device or reset the settings.

In this article we will look at all the possible ways to change the time on phones Samsung controlled Android —from basic settings in the menu to solving complex cases when the clock constantly gets lost. You will learn how to enable automatic synchronization with the network, manually set the date and time, and what to do if the settings are not saved. We will separately consider the features for different versions of the shell One UI and smartphone models.

Important: if your Samsung shows the wrong time even after manual configuration, the problem may lie deeper - from a failure in the firmware to hardware failures of the communication module. In such cases, additional diagnostic steps will be required, which we will also describe.

Why the time on Samsung is lost: the main reasons

Before changing the settings, it is worth understanding why the clock on the phone shows incorrect data. Here are the most common reasons:

• ⚡ Disabled automatic synchronization — if the function is turned off, the phone does not update the time according to the network data.
• 📡 Problems with mobile network —if the signal is weak or roaming, synchronization may not work correctly.
• 🔄 Failure after firmware update —sometimes system updates reset time settings.
• 🔋 Dead battery —if deeply discharged, the internal clock of the device (RTC) may go astray.
• 🛠️ Hardware faults —rare, but real-time chip defects do occur.

In 90% of cases, the problem is solved by software - just enable automatic synchronization or manually set the correct time. If failures recur regularly, you should check the network settings or contact a service center.

⚠️ Attention: On some models Samsung (for example, Galaxy S22 Ultra or Galaxy Z Fold) after resetting to factory settings, the time may be lost in the first day of operation. This is normal behavior - the system is calibrating the internal clock.

Method 1: Automatic time adjustment over the network

The simplest and recommended method is to enable automatic synchronization with time servers. In this case, the phone will independently update the date and time zones when connected to a mobile network or Wi-Fi.

Instructions for One UI 5.0/6.0 (relevant for Galaxy S23, S22, A54 and newer):

1. Open the application Settings (icon gears).
2. Go to section Device maintenance → Date and time.
3. Activate the switches:
   • 🔄 Automatic date and time
   • 🌍 Automatic time zone

If the options are already enabled but the time is still wrong, try turning them off and on again - this will force it synchronization. Also make sure that the phone is connected to the Internet (mobile network or Wi-Fi).

Method 2: Manually changing the time and date

If automatic synchronization does not work or you want to set the time manually (for example, to test applications), do the following:

1. Go to Settings → Device maintenance → Date and time.
2. Disable the option Automatic date and time.
3. Click on the fields Set date and Set timeto edit the values.
4. Select the desired one time zone manually (if required).
5. Save changes with the button Done or OK.

Please note: with manual settings, the phone will not automatically change the clock when crossing time zones. Also, some applications (for example, banking or instant messengers) may generate errors if the time on the device differs greatly from the server.

Method 3: Synchronizing time through a Google account

If your Samsung is linked to an account Google, you can synchronize the time through the company's services. This is useful when the settings are lost after a reset or update.

How to do it:

1. Open Settings → Accounts and archiving → Account management.
2. Select yours Google account.
3. Click Account synchronization.
4. Make sure the option is enabled Automatic data synchronization.
5. Return to the Date and time section and check if the clock has been updated.

This method is especially effective on devices with One UI 4.0 and newer, where integration with Google services is enhanced. If synchronization does not help, try deleting your account and adding it again - this sometimes resets the settings cache.

⚠️ Attention: On some corporate or work phones (with Knox or MDM), time synchronization may be blocked by security policies. In this case, contact the device administrator.

Problem solving: the time keeps getting lost

If the clock on your Samsung goes wrong regularly (for example, after a reboot or low battery), the reasons may be more serious. Here's what you can do:

• 🔄 Reset network settings:
  1. Go to Settings → General → Reset → Reset network settings.
  2. Confirm the action (password or fingerprint can required).
  3. After rebooting, check the time.

If none of the methods help, the problem may be hardware - for example, a faulty microcircuit RTC (Real-Time Clock). In this case, repairs will be required at a service center.

Features for different Samsung models

The time setting interface may vary slightly depending on the model and version One UI. Here are the key differences:

• 📱 Galaxy S23/S22/S21 (One UI 5.0+):

  Path: Settings → Device maintenance → Date and time. There is a separate switch for seconds (can be hidden).

• 📱 Galaxy A54/A53/A34 (One UI 4.1/5.0):

  A similar path, but there is no option to hide seconds. In some regions, setting is available time format (12/24 hours).

• 📱 Galaxy Z Fold/Flip:

  On folding models there may be a duplicate quick settings panel with access to the date/time by swiping down.

• 📱 Old models (until 2019 year):

  Path: Settings → General → Date and time. There is no automatic time zone option - you have to select it manually.

On devices with root access or custom firmware (for example, LineageOS), time settings may be located in a different section or require additional manipulations via ADB.

adb shell date -s YYYYMMDD.HHMMSS

adb shell date -s 20260515.143000

Common errors and how to avoid them

When changing the time on Samsung users often make common mistakes that lead to new problems. Here's what you shouldn't do:

• ❌ Change the time zone manually unless necessary.

  This can lead to problems with the calendar, alarms and applications. Use automatic mode unless there are compelling reasons.

• ❌ Disable synchronization with Google.

  Without it, backups, mail and other services may not work. It is better to leave it turned on.

• ❌ Set a date in the future to bypass restrictions.

  Some games or applications block such deception. In addition, this may disrupt the operation of licenses (for example, in Netflix or banking applications).

• ❌ Ignore firmware updates.

  In new versions One UI time-related bugs are often fixed. Check regularly for updates.

If you encounter an error "Failed to update time", try switching from a mobile network to Wi-Fi or vice versa. Sometimes time servers are blocked by the provider.

💡

Automatic synchronization is the most reliable way to maintain the correct time. Manual change should be used only in extreme cases, as it can cause conflicts with system processes.

FAQ: Answers to frequently asked questions

Why does the time go wrong after replacing the battery on a Samsung?

When the battery is disconnected, the internal clock (RTC) are reset because they are battery powered. After replacing, let the phone work for 10-15 minutes - it will automatically synchronize the time with the network. If this does not happen, check the settings in the section Date and time.

Is it possible to change the time display format (12/24 hours)?

Yes, for this:

1. Open Settings → Device maintenance → Date and time.
2. Click on Time format.
3. Select 24 hours or 12 hours (AM/PM).

On some models, this option may be in Settings → Lock screen → Clock and style.

What to do if the time on your phone and computer is different?

The difference is usually due to different synchronization sources. To fix it:

• On your phone, enable automatic date and time.
• On your computer (Windows), open Settings → Time and language → Date and time and enable set the time automatically.
• Make sure that both devices are connected to the Internet.

If the difference persists, check hour belt -it should match.

Why does the alarm go off at the wrong time?
This can happen for several reasons:
• 🔕 Do not disturb mode or Energy saving the alarm is blocked.
• ⏰ Invalid time —check the settings in the section Date and time.
• 🔄 Application crash "Clock" —try clearing its cache (Settings → Applications → Clock → Memory → Clear cache).
• 📱 Battery optimization - add the "Clock" application to exceptions (Settings → Device maintenance → Battery → Optimization functions).
How to reset time settings to factory settings?

To return all time settings to standard:

1. Open Settings → General → Reset.
2. Select Reset settings (not Factory reset!).
3. Confirm the action.

This will return the time zone, time format and other parameters to the "default" values, but will not delete your data.
