What is the SMS label in the upper left corner?

According to your description, if the mobile phone often pops up push messages/advertisements automatically, I suggest you:

1. Open the notification bar and check whether there is "Clear" in the upper right corner of the notification bar. If yes, please click to clear the information in the notification bar.

2. Standby interface-slide down the top screen-find an advertisement message and hold it down-it will prompt "Apply"-click to enter and cancel the check mark before "Show Notice".

3. The automatic pop-up advertisement push information may be the push information of downloaded third-party software. It is recommended to disable the information push function through this software setting option.

4. If it is invalid, it may be related to the downloaded software. It is recommended to uninstall and delete the corresponding software.

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter phone settings-reset-restore factory settings).

If the problem of restoring factory settings still exists, it is recommended to send the mobile phone to the nearest Samsung service center for testing and further processing. Please click the following link to find out the specific location of Samsung Service Center:.

It is recommended that you apply for "booking to the store" in Samsung official website and enjoy priority maintenance service:/pre-order.

After the appointment is successful, please bring your machine, invoice and warranty card to the service center you reserved on time.
