- The most common cause of mobile time errors is usually an incorrect time zone or region setting.
- Older or unpatched phones may fail to implement time changes such as summer/winter time.
- It is possible to force the change manually from the settings, both on Android and iOS.
- It is also key to properly synchronize linked devices, such as smartwatches or computers.
When it's time to change the clocks, whether for summer or winter time, we assume that all our electronic devices—like phones, tablets, computers, and even smartwatches—will update automatically thanks to their internet connection. However, this isn't always the case. Sometimes you wake up the next day and discover that your phone's time hasn't updated , which can be quite frustrating if you don't notice it in time.
This type of error can have various causes, and while some are related to specific failures or manufacturer decisions, many times they originate from internal configuration errors made by the user. In this article, we'll review all the possible causes of this error and detail step-by-step how to fix it when your device has changed the time, whether you use an Android phone or an iPhone. We'll also include tips for other devices such as computers, smartwatches, and Smart TVs that can also be affected.
Why doesn't your phone change the time automatically?
If you were expecting your phone to automatically adjust to daylight saving time when the last Sunday in March or October arrived, and it didn't, it's likely because one of these reasons is behind it:
1. Incorrect time zone settings
One of the most common problems is having the time zone incorrectly set. It might seem like a minor detail, but if your phone is set to a different time zone than your actual location, it will never adjust the time correctly . You could also explore how to prevent apps from updating automatically to ensure your device functions properly.
By default, most mobile phones are set to automatically obtain the time and time zone from the network. However, if this setting has been changed or is disabled, the device may not correctly recognize the time zone or may not update after a change.
2. The device region is incorrect
Many devices, especially those from brands like Xiaomi, require the region to be correctly set in the settings. If, for example, your device is configured with France as the country instead of Spain, the applied time zone change may not match the actual time, causing discrepancies.
In some cases, this is due to a failed update, an improper system restart, or accidental user error. Changing the region to the correct one is usually enough to resolve this issue.
3. Error after an operating system update
Software updates are essential, but they can also introduce errors. There are cases where, after updating the operating system, the device fails to correctly apply the new time zone database , preventing the time from updating automatically.
In these cases, it's best to check if a new update is available to fix the issue. In many cases, manufacturers release patches shortly after detecting these types of errors.
4. The device is too old
Older phones that no longer receive updates may have trouble adapting to new time changes, especially if their time zone database is outdated . This has happened in countries like Mexico, where daylight saving time was abolished, yet some phones continued to adjust for months.
If you're using an unsupported device, you can install third-party apps like World Clock Time Zone Converter or ClockSync, which manually sync with up-to-date servers to get the correct time.
5. Connectivity failures during the change
If your mobile phone doesn't have an internet or mobile network connection when the clocks change (for example, if you're in airplane mode), it's very likely that it won't be able to update the time automatically. Some devices only synchronize the time when they're connected to an active network.
As soon as you regain connection, your phone should update the time without intervention, but if that doesn't happen, you can force the change manually, as explained below.
6. Apps with permissions to modify the time
On some Android phones (especially if they've been rooted), certain apps may modify the system time . While this isn't common, it can cause unexpected errors. On iOS devices, this behavior is virtually unheard of due to Apple's strict control over the system.
Solutions to fix time-only change on Android phones
There are several ways to ensure your Android phone displays the correct time. Below, we've detailed all the methods and steps:
1. Activate automatic time and time zone from settings
- Open the app Settings on your phone.
- Go to the section System and enters Date and Time.
- Activate the options Set time automatically y Set time zone automatically.
- Also check that the device region is set correctly (Spain, for example).
On some devices, such as Samsung Galaxy phones, you will need to go to General Administration and then to Date and Time.
2. Change the time manually
If automatic time doesn't work properly, you can set the time manually:
- Turn off options Set time automatically y Automatic time zone.
- Tap on Set time and select the correct time.
- Do the same in Time zone and choose the one that corresponds to your location.
This method is very useful if you are in a country without a network available or if you are using a very old phone.
3. Restart the phone
As with many technological problems, a simple restart can correct specific errors. Simply:
- Press and hold the power button until the restart option appears.
- Select it and wait for the phone to restart.
On Samsung, you can press volume down + power button simultaneously to directly access the “Restart” option.
4. Factory reset (only as a last resort)
If none of the above works and the error persists, you can try resetting your phone to its factory settings. But be careful, this will erase everything on your phone , so make a backup first.
- Go to Settings > General Management.
- Tap on Resetting and select Reset all data.
- Confirm the action.
How to fix time change issues on an iPhone
1. Turn auto-tuning on or off
- Go to Settings > General > Date and time.
- Turn the switch on or off Automatic adjustment as necessary.
- If you disable it, you can manually select the time zone and set the exact time.
As with Android, if you turn on Auto-Sync, the time should sync when you connect to Wi-Fi or mobile data and use your location.
2. Check your localization settings
For Auto-Setting to work properly, your iPhone needs to access your location to detect your time zone:
- Accede to Settings > Privacy & security > Location.
- Activate it and make sure that System services includes permission to Time zone.
3. Force the time change manually
If you need to set the time yourself:
- Deactivate Automatic adjustment.
- Press on Time zone to modify it according to your location (for example, Madrid).
- Manually change the time and date by tapping on each field.
What to do if other devices display the wrong time
Smartwatches or smart bracelets
Smartwatches usually automatically take the time from the phone they're synced with. If this doesn't happen:
- Unpair the watch from the options Bluetooth of the mobile.
- Restart both devices.
- Re-sync them from the watch or wearable app.
- Please check that your phone has the correct time before doing so.
In some cases, it may be necessary to update the watch firmware to correct sync errors.
Windows or Mac computers
If your computer still doesn't change the time correctly:
Windows
- Open the menu Configuration.
- Go to Time and language > Date and time.
- Active Set time automatically.
- Also check Set time zone automatically.
MacOS
- Sign in Apple menu > System Preferences > General > Date & Time.
- Active Set the time automatically.
- Allows access to your location for accurate timing.
Smart TVs
On a smart TV, the procedure varies depending on the brand. On a Samsung, for example:
- Press the Home button on the remote control.
- Go to Settings > General > System Manager > Time.
- Active Automatic clock modeIf it doesn't work, set it manually.
Other recommendations to avoid mistakes with the time change
- Keep your operating system up to date. On both mobile and computer devices, this is key to avoiding sync errors.
- Check if you need more than one time zoneYou can use widgets or apps to display two clocks if you travel a lot or work in different parts of the world.
- Avoid turning off your mobile phone right during the time change., especially if you are offline, as it may prevent syncing.
- Check the settings after traveling. Country changes can alter the time zone if not properly automated.
Accurately setting the time on your mobile phone, while it may seem trivial, is more important than it appears. From the proper functioning of alarms and calendars to synchronization with banking or transportation apps, an incorrectly set time can cause significant problems in your daily life.
Fortunately, most of these errors have a quick fix if you know where to look. Whether it's manually adjusting the time zone, enabling automatic features, or checking the region, these steps will ensure your device is always on time.
