I haven't received the SMS since vivo Xplay swiped the machine. I only get the SMS after I restore the factory settings every time. Please answer me why?

I'm sorry for the inconvenience. According to your description, I suggest you try the following operations:

1. Click on the status bar of the mobile phone to speed up (one-click cleaning) or enter the program management of the desktop to close the background program and clear the cache file to increase the available memory, so as to avoid the phone crashing due to insufficient memory.

2. Try to pass the "Settings->; General/More Settings -> Restore factory settings -> Restore all settings "

3. You can enter Settings -> General/More Settings -> System upgrade -> Check the update immediately-download the upgrade package according to the prompt, click Check and Install, and the mobile phone will restart and automatically enter the upgrade mode to upgrade your mobile phone system.

4. Try to pass the "Settings->; General/More Settings -> Restore factory settings -> Clear all data "Clear abnormal data. Note: This item will lose all the data stored by the user on the mobile phone, including phone book, short message, third-party application software and related account information, and the data stored on the T card will not be lost. Use with caution. (Pay attention to data backup)

5. Try to upgrade the firmware of your mobile phone.

you can go to /service.html to download the firmware upgrade package data of your mobile phone model. Instructions for firmware upgrade /thread-12455-1-1.html

If you still can't help you solve the problem after trying the above methods, I suggest you go to the after-sales service center to test your mobile phone. Please rest assured that the technicians of the after-sales service center will properly handle the problems encountered by your mobile phone. You can check the address of the after-sales service center in the settings of mobile phone-general/more settings-after-sales service menu. You can also check the address of the after-sales service center on the official website of vivo: /service/map.html
