Mobile phone google drop-down notification bar digital verification can't pop up a pop-up window. What happened?

1. Bad signal or network connection problem: Please make sure that your mobile phone network connection is normal and the signal is good. It is suggested that the verification should be carried out under the condition of good network signal. Mobile phone settings: Please make sure that your mobile phone notification rights are turned on. You can view and modify the notification rights in the settings of your mobile phone.

2. If the login pop-up window does not pop up on the mobile phone, it may be because the login application of Google account is not installed on the mobile phone. You can search for "Google Account" in the mobile app store, install the corresponding app, then open the app and try to log in to your Google account.

3. What you want to ask is what should I do if the 2-digit number in Google's notification bar cannot be verified? Reinstall the Google Verifier on your phone. Reinstall the Google Verifier of your phone and visit the two-step verification page under Google Account Settings. Log in with user name, password and verification code, and click Close for two-step verification.

4. The first thing to consider may be that the notification bar is set to not display shortcut switches. You can enter the "Settings" interface, click "Signal Bar" and check the "Signal Bar Settings" check box.

5. Because the notification display setting is turned off, just click Find Information, click Open, and then click Notification Management to open the allowed notifications. First, open the phone settings. Then locate the status bar and notifications, and click. Then, click the information option. Finally, just select the top preview.
