How to delete a custom SMS background style?

Just replace it with a new picture, or change the file name of the original picture, and it will not be displayed. If your mobile phone is not smart, just restore the default settings of SMS.

Click SMS-and then click the menu button in the lower left corner-Select Settings-

There are bubble types, background styles and so on, which can be set at will.

I hope you can set it successfully. I wish you a happy new year ~ ~ ~
