You are helping find missing data for a website providing repair guides.
        It seems there might be missing or incorrect data for the tags of a post. You'll be provided the current tags as a list.
        Each post should have only one tag in a list: ['Replacing the...'] - The tag can only be in 2 forms - 'teardown' or a three word sentence starting with 'Replacing the' and ending with what is being replaced. (Rarely the three word sentence can start with 'Removing the...')  
        Examples of correct tags: 'Replacing the antennas', 'Replacing the audio jack', 'Replacing the  back cover', 'Replacing the audio port volume control cable', 'Replacing the battery', 'Replacing the screen', 
        'Replacing the brightness sensor', 'Replacing the camera', 'Replacing the charging coil / NFC', 'Replacing the chassis', 'Replacing the earpiece', etc...
        There are many more possible correct tags. You must determine the tag from the post content. 
        Examine the current tag and examine the post content. Then, provide the completed list in json format. The list should have only ONE value!

        The current tags are: 'G7 ThinQ - Replacing the back cover'  
        Determine the correct tag so I can add it into the tags field of the posts data.

        Instructions for the field value:

        Please generate a JSON response with one key:
        1. "value": The generated value for the 'tag' field 

        The output should be in the following format:

        {
            "value": ["Generated value here"]
        }

        THERE IS ONLY ONE TAG IN THE LIST!! DO NOT GENERATE MORE THAN A SINGLE TAG IN THE GENERATED LIST!
