Why is there a record in my Xiaomi mobile phone log every day, such as {sogou input method-no call permission or no SMS permission}?

It doesn't matter. Your mobile phone intercepted some permissions of sogou or 360. Sogou input method only obtains SMS permission when multimedia input, and converts SMS and MMS to each other. Input method will not steal any information from you, so you can use it with confidence.

Input method reads the information of your contacts, which is convenient to import into the address book thesaurus, and won't read your private information, so you can use it with confidence.
