What should I do if my Huawei phone s address book suddenly won t open?

This is because of the presence of apps on mobile phones.

If the operation stops, you can try to deal with the workaround.

The system runs too many programs, resulting in running memory.

insufficient, one-click cleanup can solve such problems (restarting the phone is also possible);

There are too many app data caches on your phone, it is recommended to click on Desktop -- Settings -- General -- Applications -- All -- Find the program that stops running -- Clean up the data;

Caused by improper installation position, go to Settings - Storage - Preferred Installation Position - Determined by the system (some models do not have a preferred installation position option);

Back up your phone data (contacts, text messages, etc.) and restore factory settings.

The remaining 80% is checked to see if there is [and Contacts] installed on your phone, and it is recommended that you cancel the SMS and dialing apps that take over the system with Contacts.

How to set up: and Contacts - Cloud Backup.

Settings (click the settings icon in the upper right corner) - Other settings - Take over the system address book - Turn off all sub-functions. Or you can uninstall [and Contacts], and Huawei is currently working hard to promote [and Contacts] to fix this issue.

The reasons and solutions for the sudden loss of contacts on Huawei phones are as follows:

1. It may be due to a sudden error in the mobile phone system, resulting in the address book not being displayed, please try to restart the phone, or turn off (remove the battery) for 30 seconds to 2 minutes and then reboot it;

2. If there is still none, it may be due to misoperation to delete the address book, or the system error causes the address book to be unable to display, or the contact list to be displayed is selected incorrectly, in the address book you can set the contact to display a certain storage location, such as only display the mobile phone card or only display the mobile phone, etc.

Huawei Technologies **** is headquartered at Huawei Base in Bantian, Longgang District, Shenzhen, Guangdong Province, China. Huawei was officially incorporated in 1987 in Shenzhen, China. In 2007, the contracted sales were 16 billion US dollars, including overseas sales of 11.5 billion US dollars, and it was the first in China's domestic electronics industry in terms of profit and tax payment that year.

By the end of 2008, Huawei had covered more than 100 countries and regions in the international market, and 45 of the world's top 50 telecom operators had used Huawei's products and services. Huawei's products and solutions have been used in more than 150 countries around the world, serving 45 of the world's top 50 carriers and 1.3 percent of the world's population.

Huawei's large-scale human resources system construction began in 1996. In January 1996, Huawei's marketing department resigned en masse. At that time, all the full-time cadres of Huawei's marketing department, from the president of the marketing department to the directors of each regional office, all cadres above the director level of the office had to submit two reports, one for the work report and the other for the resignation report.

About 30 per cent of the cadres were replaced in the competitive appraisal.

What should I do if my Huawei phone's address book suddenly won't open? Generally in this case, I recommend. Reboot the Huawei phone, restart it, if it still doesn't work, it is recommended that the phone's address book should be backed up frequently.

What does this mean, what should I do if I turn it on and I don't have a mobile phone address book and suddenly can't open it? You can turn your phone back off and on. Then the phone's address book can be opened.

If your mobile phone call history is not displayed or lost, perform the following steps:

1. Call records cannot be generated after dialing or answering**

1.Please check if the private space is enabled.

If the same contacts are saved in the main space and the private space, the call history is displayed only in the private space. We recommend that you view your call history in a private space or migrate your contacts to the main space (perform the following steps).

2.It may be that you have changed the system date and time, causing the new call log not to be displayed at the top.

3.It could be that you don't have permission to turn on call logs.

EMUI: It is recommended that you go to Settings, search for App Management, click on the three dots in the upper right corner, select Show System Processes, search for contact storage, click Permissions, and turn on Call Log permissions if they are denied.

2. The call history cannot be found, and the call record is lost

1.It's possible that you select other options, such as missed calls, that cause only some of the calls to appear.

It is recommended that you click Dial or **, and click All Calls on the Call History List page to display all call logs.

2.It may be that you have set up to merge call logs by contact, which causes the call logs of the same number to be merged.

It is recommended that you go to dial **, click the three dots > Settings > Call Log Merge > Press Time to display all call logs.

The system sets the default limit of 2000 call logs, and when the upper limit is reached, it will actively delete the old call records and keep the latest 2000 records;

It is recommended that you back up your old call logs to the cloud space first, and then clean up the historical call logs. If it is an earlier call log, you can also check with the carrier.

3.It could be that the third-party app deleted your call history:

Go to Settings, search for Permission Management > Permissions, find Call Logs > New Modify Delete Call Logs, and observe whether any third-party software has checked this permission, please cancel the New Modify Delete Call Log permission for these apps.

Still can't solve it?

If the preceding methods do not solve your problem, we recommend that you back up your data in advance (third-party applications such as WeChat and QQ must be backed up separately) and bring your purchase voucher to the Huawei Customer Service Center for testing.

Summary. 1. It may be due to a sudden error in the mobile phone system, resulting in the address book not being displayed, please try to restart the phone, or turn off (remove the battery) for 30 seconds to 2 minutes and then reboot it;

2. If there is still none, it may be due to misoperation to delete the address book, or the system error causes the address book to be unable to display, or the contact list to be displayed is selected incorrectly, in the address book you can set the contact to display a certain storage location, such as only display the mobile phone card or only display the mobile phone, etc.

Dear, I hope the above can help you! Thank you!

How to recover? How to recover?

Restart your phone and try it.

Why are all the contacts in my Huawei phone suddenly gone? Hello dear, the specific reasons are as follows; 1.If your contacts are missing, your HUAWEI ID or third-party account may have gone offline when you have not backed up your contacts to your phone or SIM card, and those contacts will disappear after you log out of your account.

There is a deleted contact record in the Recently Deleted section, and you can restore the relevant contacts. 3.Restore the cloud space official websiteThe recovery function is more complicated than the recent deletion function of the mobile phone, and you must log in to Huawei before using it.

The Recently Deleted feature on the official website of Cloud Space cannot recover third-party apps and SIM card contacts. 4.Enable the synchronization function first, and it will take a certain amount of time for the data to be synchronized.

5.Log in to the HUAWEI CLOUD official website, log in to the HUAWEI CLOUD official website, touch Contacts, and then touch Recently Deleted in the lower-left corner of the page. You can restore the deleted contacts, and the relevant contacts will be synced to your phone at the same time.

6.Restore from the cloud backup to the drop-down phone interface, search for backups, and view the latest backup records in the cloud backup. I hope my answer is helpful to you, and finally I wish you good health and a happy mood again!

If you have not deleted a contact, please perform the following steps:

1.Recover deleted contacts.

If multiple devices share the same HUAWEI ID and Sync Contacts is turned on, if you delete a contact on one device, your contacts in the cloud and on other devices will be deleted simultaneously. Log in to HUAWEI CLOUD**, go to Contacts, and touch Recently Deleted at the bottom to restore the deleted contacts.

2.Turn on the All Contacts switch.

Contacts > Three dots Four dots > Settings > Show contacts, turn on all contacts switch.

3.Keep your local contacts when you sign out of your HUAWEI ID.

When you sign out of your HUAWEI ID, you do not choose to keep your local contact data, resulting in the loss of local contacts or the appearance of contacts with only names but no numbers. Log in to your HUAWEI ID again to sync your contacts to your device. If you do not want to delete local contacts when you sign out of your HUAWEI ID, we recommend that you select the Keep local contacts option when you log out of your HUAWEI ID.

4.Toggle multi-user viewing.

Since the spatial data in the main space, the private space, and the multi-user space are independent of each other and cannot access the data from each other, you have switched between the main space, the private space, and the multi-user space, and you cannot find the contacts.

5.Using a third-party app to back up or communicate leads to loss of contacts.

1) Using third-party assistant software (such as QQ Assistant, 91 Assistant, etc.) to backup or copy contacts may lead to loss of contacts. It is recommended that you use the import and export function that comes with the system contacts.

2) The third-party address book software may not display all contacts due to the app's own restrictions or permission problems. We recommend that you go to Settings, search for the default app, and change the dialing to the built-in Huawei dial-up app. (Note:.)

EMUI version is **, and above is Contacts).

3) Installing some third-party apps with the permission to delete contacts may delete contacts. It is recommended that you go to Settings and search for Permission Management > Permissions > Contacts > New Modify to delete contacts, and turn off suspicious third-party appsNew Modify permissions to delete contacts.

6.Try again after deleting the contact data.

Reminder: This operation will not delete contacts, but to distinguish contact storage, which are two different apps, deleting the app data stored by contacts will delete contact information, call logs, etc.

If the problem persists after the above attempts, we recommend that you add the generated contacts again and enable backup methods such as HUAWEI CLOUD backup or contact synchronization in the cloud.
