My mobile phone is Huawei glory. I want to send a short message by fetion now. But I opened the traffic. Keep walking. Should I turn off Fetion or keep walking?

You can download software with traffic monitoring function to see which software is running, such as security housekeeper, 360 security guards and so on.

Then, before using the exclusion method and using Fetion again, all other background software will return, and the security housekeeper and 360 guards can watch the progress. Then look at the traffic usage.

More general, but I hope it will help you! !
