After Samsung s8 updated the system, the SMS always reminded me that Fetion was not available, but it still didn't work after turning off the settings. I am calling Unicom.

Click this path to confirm the phone model first:

Settings-> Regarding the mobile phone (the settings are dragged to the bottom), 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 unavailability (including your active shutdown), 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 now, which shows that this 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, remember to clear the "SMS" from the background of the mobile phone after reading/sending the SMS.
