All incoming calls are defined as "Unknown"

Reasons for failure

This situation has already become fatal for many. People could not think of anything, although they did various methods, even replaced SIM cards. We will try to do without extremely radical measures. There are few causes of problems. Causes:

• no money on the phone;
• wrong number display status;
• downed parameters of the telecom operator and the device itself;
• copying contacts from one device to another, as a result of which there were failures;
• exposed country in smartphone settings;
• incorrectly saved contacts (shortening numbers (+7 ..);
• duplicate numbers;
• not enough space on the phone, and both clogged RAM and lack of internal memory are to blame;
• network activation via Gevey Sim was used;
• the phone has been updated or flashed (manual flashing).

Some operators, in order to show the numbers of incoming calls, ask to activate the service. You're in luck - it's free. Unfortunately, the operator does not always inform the user about this.

What to check if incoming numbers are not detected?

This problem can be solved quite simply, you're in luck. And even if the following steps fail to fix the problem, change the SIM card. Moreover, now, when you replace a SIM card, your phone number is saved.

First of all, we check the following

If you have an iPhone

If you have an iphone and you have activated the network through "Gevey Sim", see which country is indicated in the smartphone settings. Play around with different countries. Sometimes exposing European states, Russia, China and others helps. Don't worry, nothing should change on your smartphone. Plus, everything can be turned back.

Reset

If the device has recently been updated or flashed, you can roll back the system, or reset it to factory settings. Go to "Settings" - "General settings" - "Backup and reset" - "Reset device".

There is another way - turn off the smartphone - hold simultaneously the buttons "Volume up", "Menu key" (if it is not there, skip the item) and the "Power off / on" key. We advise you not to release the keys (except for the “Power off” button) for about 20 seconds (until Recovery appears). After a new window appears, you must select (with the volume keys) the desired item - factory reset. We reset and delete all data. After that, we reboot the device.

The point above can help with any difficulties associated with our problem.

If he writes an unknown number to Xiaomi

Lately, a lot of problems have been caused with Xiaomi branded phones. This is because they have their own MIUI system. For troubleshooting, just turn off its optimization.

1. “Settings” - “About device” - “MIUI version” (actively click on the item 10 times) - a sign “Developer settings are open” will appear on the screen.
2. We go back, click the "Advanced" item - the "For Developers" menu has appeared.
3. Press and turn off the system update.

Also, check if you have an official version of the Xiaomi smartphone. Perhaps you bought a device with a ROM version, not a European or Chinese one. The ROM version is a flashed Chinese license for a European (illegal) one. Often issued in stores as “For Europe”. In this case, only a flashing will do.

Conclusion

Be sure to check the above tips if you don't see incoming call numbers. At most times, the failure can be fixed very quickly and easily. If suddenly the advice does not help, up to the firmware. We'll have to go to the service center and show the device. But before that, check the work of another SIM-ki on this phone. If there are no problems with it, then go to the operator's branch and change the SIM card.

Call history is not kept on an Android phone or tablet. Android smartphone does not show missed, incoming, outgoing calls. What to do and how to fix it?

If Android does not save call history, then you should look for the cause of the error in the system. In some cases, only a complete reset of the device helps to solve the problem, but you can get by with less radical methods.

This article is suitable for all brands that produce phones on Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

System failure

If the call log suddenly stops replenishing with new calls, try restarting your phone. Perhaps an error occurred in the Android operation, which will be eliminated after restarting the system.

1. Hold the shutdown button until the menu appears.
2. Select Restart.
3. Wait for the system to restart and make a new call.

If the cause of the crash was a small error in the system, then restarting will fix it and return Android to normal state.

Wrong date

Another reason why calls are not saved in the log may be the wrong date on the phone. The time does not matter, as time zones can be different, but the date must be accurate. Otherwise, Android will receive calls from the past or the future and won't figure out how to record them for the current date. To change the date:

1. Open the settings.
2. Go to the "Date and Time" section.
3. Turn on auto-detection of time and date over the network or set the data manually.

After changing the date, call any number and check if the information about the call is saved in the call log.

Factory reset and flashing

If everything is in order with the date, then the cause of the error should be looked deeper - in the operation of the system itself. There are two ways to troubleshoot a serious system failure:

• Factory reset.
• Phone flashing.

After the reset, you will get the device "like new": without profiles, contacts, content, applications installed on the internal memory. To avoid losing important data, make a backup before resetting. To roll back to the original state:

• Open the settings.
• Go to the "Recovery and reset" section.
• Select the "Factory data reset" mode and click "Reset".

If a factory reset doesn't work, perform a factory reset. After completing this operation, you will receive a clean Android.

If the reset does not lead to a positive result, perform a flashing. You can install the official firmware from the device manufacturer or install an Android assembly that matches your phone model.
