The question of how to change the date in Android is usually quickly resolved through the settings, but sometimes you can set right time It doesn’t work the first time: the value is constantly lost or displayed incorrectly on a tablet or phone.
It doesn’t matter what version of Android and what shell is installed on your tablet or phone, you can set the date and time using one algorithm.
- Open the Android main menu. Go to Settings.
- Go to the "Date and Time" section.
- Pay attention to the auto-tuning options. If the date and time are determined over the network, but you see incorrect values, connect to the Internet, disable the auto-tuning option by selecting “Disable”, and then enable it again.
If after the update the time is still displayed incorrectly, disable auto-tuning by unchecking the use of network data checkboxes and set the values manually. The corresponding items will become available for making changes immediately after the automatic settings are deactivated.
To set the date and time, open the items of the same name one by one. Move the numbers up and down to change the set value, and then click Done to save. 
The time zone is configured in the same way. You can enable its detection over the network or change it manually. You can also customize the date and time display format on your tablet or phone. The time can be shown in 12-hour or 24-hour format, and the date can be shown in in different order date, month and year.
Why does time go wrong?
Typically, the time on Android is adjusted automatically after installing the SIM card and turning on the device. But why does it periodically fail on a tablet or phone if the system has enough tools to constantly check and maintain correct value? The phone does not have a CMOS battery, which is responsible for storing the correct date and time on the computer. Therefore there can be two reasons:
- Using Auto-Tune.
- The difference between the operator's time zone and the time zone on the tablet or phone.
How to disable automatic determination of date and time over the network on Android is described above. But if after carrying out these manipulations the time is still lost, try using the following algorithm:
- Turn off the device, remove the SIM card.
- Turn on the device, go to settings. Open the “Date and Time” section, disable automatic time zone detection.
- Set the correct time zone and apply the changes.
- Turn off the phone, insert the SIM card.
If you can’t change anything this way, and the screen still displays incorrect values, try . The procedure will be similar, only after removing the SIM you must first reset the settings, and only then manually set the time zone. 
Setting the date and time in the Android operating system is a simple thing, but in some cases the user may have difficulties with it. They can be associated both with ignorance of certain things, and with failures of the operating system itself.
How to Set Date and Time on Android
The correct date and time not only helps the user to be more punctual - few people would want to miss the bus because the time was set incorrectly - they are also important for the operation of some applications, which, if the data is incorrect, can begin to crash and work with errors. Therefore, it is strictly recommended to set the correct date and time on the device.
The process of setting the date and time in different versions Android is approximately the same: except that in new devices the system asks you to configure data immediately, even before you start using applications. In addition, the names of menu items responsible for time and date may differ slightly from each other in different OS versions.
After these simple manipulations, the date and time should change.

If problems arise
It happens that when setting the date and time, errors occur: changes are not applied, the newly set time and date are reset, or even thrown out of “Settings” with an error. There can be many reasons, but the most common ones are:
- you have auto-time synchronization enabled, and therefore attempts to manually change will lead to nothing. To disable auto-sync, you need to uncheck “Use network date and time” in the date and time settings;
- the problem is associated with a single system failure and should stop after a factory reset or reboot;
- There is a defect in the device's firmware - in this case, if you are not an experienced user, it would be best to contact a specialist service center, since when you try to reflash the device yourself, there is a high risk of damaging it;
- there was a conflict between the time zones of the phone and the SIM card (most often this happens with the Tele2 operator).
To fix the time zone and SIM card conflict issue, follow these steps:
Auto date and time synchronization
If you don't want to set the time and date manually, you can use Android's built-in feature to automatically synchronize time with the network. Or, if maximum accuracy is important, its improved version, the implementation of which will require root rights.
Normal auto-sync
To synchronize date and time with network data, you need to tick just one item located in the “Date and Time” settings menu. It is usually called “Use network date and time,” but the options “Automatic date and time,” “Synchronize with network,” and other similar options are also possible.
After checking the box next to this item, the date and time on the phone or tablet are synchronized with the network data and will henceforth be determined automatically. While this feature is enabled, you cannot manually set the date and time.
When the “Use network date and time” checkbox is checked, the system itself checks the date and time with the network
"Smart" synchronization
Standard synchronization is not very accurate and operates with an average error of 500 milliseconds (that's about half a second). This is due to the fact that when it was created, old and rather slow data transfer protocols were used. As a result, information about the current time simply does not have time to arrive on time and is slightly delayed. This leads to an error that is corrected by numerous applications for “advanced” time synchronization.
To work properly, applications need to interfere with Android settings, but by default they do not have this right. Therefore, in order to carry out smart synchronization, you need to have superuser rights, or root rights, on your device. However, those applications that are the most advanced, with a sin in half, but do without them.
The algorithm for obtaining root access is unique for each phone model, which this moment hundreds. There is no general method that would allow you to gain superuser rights on any device: even the most popular applications for “hacking” root rights operate with a limited set of models, and whether a particular application is suitable for you is unknown. To obtain root access on a specific device, you need to read the technical documentation on rooting it on a specialized resource.
There are several smart sync apps, and they are all similar to each other. Let's look at working with them using the ClockSync application as an example.
ClockSync can be downloaded from official page V Google Play. However, this application is one of the most resource-intensive and multifunctional: for example, it allows you to change the server with which the time is checked. If you are not such an advanced user, then you can use some simpler analogue: for example, Smart Time Sync.
Setting the time zone
You can change the time zone defined on the device in the same settings item, “Date and time”. The “Time Zone” line allows you to change the default zone.
The time zone, just like the date and time, has an auto-synchronization option. You can enable it if you are not confident in your own time zones, but in older Android versions This setting sometimes fails, so it is recommended to configure it manually there.
To synchronize the time zone with the network, you need to enable the "Use network time zone" option You can find out which time zone is used in your region using the media at your place of residence, including the Internet. Moscow zone - GMT+3, in St. Petersburg and middle lane Russia also mainly uses it. In general, time zones from +3 to +12 are used in Russia.
To select a time zone, you need to click on the “Time Zone” button and select from a huge list the one that is used in your region. After this, the time will be set in accordance with the selected zone.

The time zone can go wrong in several cases: either auto-synchronization is not working correctly (in this case, you need to enable manual zone selection), or the wrong region is set in the settings of your phone or tablet.
In addition, the cause of the failure may be an error in the databases. In this case, only one of the applications for “smart” synchronization, which has already been mentioned, will help; the servers they use usually detect the time zone without errors. However, root access is required to use such applications. In the settings of such applications there is an “Auto-sync” item, which can only be enabled with root. If automatic time zone synchronization is enabled, the application will also determine the time zone automatically - and do so more accurately than the system menu.
In the main settings menu of ClockSync and similar applications there is a button “Auto-sync time zone” Video: “fixing” the time zone through the application
Setting the time and date on Android is simple - if the phone does not require maximum correctness of the result. If you want your watch to be extremely accurate, you will have to try. In any case, correctly determining the time is a valuable feature of the phone, which is extremely important for its normal operation.
Something as simple as setting the date and time on Android seems like a no-brainer. Indeed, for experienced owners of smartphones or tablets this is a trivial operation. However, for those who are holding a device running this operating system for the first time, setting these parameters may raise questions. Below we will look at how to set the date and time on Android.
Changing the date and time manually
To adjust the time and date manually, you need to enter the device settings. This can be done in two ways:
- Open the curtain vertically from the status bar and tap on the icon depicting a gear.
- Enter the application menu by tapping on the icon with the image of six dots located in the dock bar. Find the icon with the image of a gear and short-click on it to open the section “ Settings».
Find the item " date and time» and briefly tap on it to open this tab. In some gadgets, the settings menu may look different, and time and date settings should be found in the “ Options».
Manual setting of time and date will be available if the checkbox is unchecked. Automatic time detection" or " Network date and time» is in the off position (depending on the Android version).
- To change the date, select “ date" or " Set date", where we select the date, month and year and confirm by tapping the "Ok" button.
- To change the time, you need to select " Time" or " Setting the time", where we set the correct time and confirm by tapping the "Ok" button. Here you can set the time format – 12 hour or 24 hour.
Automatic date and time setting
Android can set the time and date automatically. In this mode, information is synchronized from the operator's network. Naturally, a SIM card must be installed in the device. To automatically set the time and date, you need to check the box " Automatic time detection». Manual installation will become unavailable.
Nowadays everything more people are moving away from using wristwatches in favor of smartphone watches. However, the phone date and time may get lost when the device is rebooted or due to a system error. In such cases, you have to change the settings yourself. To do this correctly, let's look at some features of date and time settings on Android.
Inaccurate date and time on Android may cause some apps to stop or function incorrectly. This happens because programs automatically check the expiration date of their license with the date set on the phone. And if something doesn’t add up, then they simply stop working.
How to change date and time on Android
Now let's move on to manually setting the time parameters.

Possible problems when setting the time and their solutions
After setting new time settings, you may encounter two problems:
- time settings are constantly reset;
- The message “An error occurred in the Settings application” appeared on the device screen.
The following methods will help you correct these misunderstandings.
Reboot
First try restarting your smartphone. This action will start all processes again, and perhaps the errors will disappear, and the time settings will be saved.
Auto-sync
If rebooting the device did not work properly, you need to enable auto-sync. This feature allows the phone to automatically update its time settings when connected to the Internet. To enable auto-sync, follow these steps.
Installing 360root and ClockSync applications
If your phone does not have an auto-sync feature, you will need to follow these steps.
Factory reset
However, even after automatic synchronization is enabled, the time may still change on its own or generate an error. In this case, you will have to reset your phone to factory settings.
How to select, set, or add a new time zone
To find out the time zone of your region, go to the website http://www.gmt.su/city-time/country/Russia/ and find the city closest to you in the list. On the right side of the page you will see time zone information. For example, in Kaliningrad it is GMT +02:00. You will need to select this information in the settings of your phone.
You usually find out that the clock on your mobile phone is behind when you are late for something, for example, for a train. In the 21st century, it is unacceptable for your watch to be fast or slow by more than a minute.
And if to wristwatch There are no complaints, then smartphones are simply obliged to show the exact time. But as practice shows, this is not always the case. The clocks on the phones are just as “fragile” as the old clocks at my grandmother’s in the village.
How is the accuracy of electronic watches determined?
First of all, the tuning accuracy and stability of the quartz oscillator (resonator). The frequency accuracy and stability of the latter is usually 10 -6. Ideally, at this value, the clock advances a little more than 30 seconds per year.
In practice, stability is slightly worse, since the resonator frequency is influenced by the parameters environment(temperature, pressure) and generator supply voltage. The generator also includes other elements, for example capacitors, the parameters of which are more dependent on external influences. As a result, the clock can run up to 30 seconds per month.
Improving watch accuracy
In professional devices, for example, in satellite television transmitting and receiving equipment, the stability of generators is much higher and can reach values of 10 -12.
Therefore, a natural way to take the carrier frequency of an external signal source as a standard arises. And use it as a reference for our generator. There are two possible ways: hardware and software.
In the first case, the clock generator frequency is adjusted to the carrier frequency of the GSM transmission tower. In the second case, the GSM base tower transmits accurate time signals and operating system adjusts the clock.
But as domestic reality shows, on mobile operators there is no hope. Several times I found myself in a situation where the time on the clock jumped several hours. After which I had to disable the option to use data provided by the network.
Time servers
Since a smartphone is a computer with Internet access, the easiest way is to synchronize the clock with reference time servers. Standard firmware does not have this feature. But the problem can be solved by installing additional software. There are several such programs, and I liked one - ClockSync from a “domestic manufacturer” :-).
ClockSync synchronizes system time Android devices via the Internet via NTP protocol with exact time servers. The program is useful if the cellular operator does not support NITZ (automatic time synchronization) or sends incorrect values, as well as if the phone clock is too fast or behind.
Works on tablets. Relevant if you need an exact time. Especially on devices without a GSM module.
