You can solve the advertising problem quickly by the following methods. If your device cannot access the desktop, go directly to step 2. Detailed operation steps are as follows:

1. Uninstall all malicious software (Note: uninstalling the application may result in the loss of application data. If important data is involved, users are advised to make backups in advance).

(1) Check the suspicious software installed on the mobile phone, especially the newly installed software, such as three-way cleaning acceleration, three-way optimization, three-way antivirus, three-way housekeeper, three-way file management, WIFI, walking to make money, three-way weather and so on.

(2) go to settings > applications and services > application management, find the suspicious application and click "uninstall", or continue to click "stop and uninstall" to finish the uninstall.

2. Enter the safe mode to uninstall

If your mobile phone frequently pops up advertisements and interferes with the above operations, please follow the following steps to enter safe mode and uninstall malicious software.

If the above methods can't identify and clean up suspicious advertising software, I suggest you call Huawei's customer service hotline 950800, or back up the data in advance (third-party applications such as QQ and WeChat need to be backed up separately), and consult at a nearby Huawei customer service center.

Warm reminder:

1. It is recommended that you back up your data in advance by going to phone settings > (third-party applications such as QQ and WeChat need to be backed up separately); System and update > software update, upgrade the mobile phone system to the latest version of HarmonyOS system, and upgrade the version for more secure system protection.

2. It is suggested that you turn on the automatic upgrade function at night, update the system of the equipment in time, and upgrade the application to the latest version. The new version will optimize system performance.

3. It is recommended to keep the "pure mode" on during daily use ("Settings" >; "system and update" > "pure mode" > "on", only supported by HarmonyOS system), this mode will provide you with more secure application services.

4. Stay away from download induction. It is suggested that when you use your mobile phone every day, please don't click on the advertisements that pop up on the page, such as insufficient memory, mobile phone poisoning, free WIFI connection, free news to make money, free red envelopes, etc. , and stay away from download inducement, so as not to install the software that plays advertisements again. To download application software, please go to Huawei's "Application Market" to install the required software. All the software has passed the security check, so you can use it more safely.
