Samsung s8 sends SMS.

Click this path to confirm the phone model first:

Settings-> For the mobile phone (the setting is dragged to the bottom), please look at the "Model" in the second line.

If it starts with G9508, it means that your mobile phone is a mobile customized version. Unfortunately, this reminder cannot be cancelled. "Fetion" is a built-in function of mobile customized version. No matter what causes it to be unavailable (including your initiative to close it), there will be this prompt.

If it starts with G9500, it means that the mobile phone is full netcom, not custom machine. Theoretically, there is no "Fetion" function in Netcom, which means it is a BUG. Suggest feedback to customer service.

In addition, let's talk about some common problems in the market. If the mobile phone is a customized version, and it is not a screenshot prompt, but a gray prompt pops up at the bottom of the screen, please remember to clear "SMS" from the background of the mobile phone after reading/sending SMS.
