    As the WhoWho is the wireless internet-based search service, it
    may not be able to call up the information or display information smoothly when the wireless internet is not active enough.

    In this case, if you are using the LTE data plan, we recommend setting HD voice (or VoLTE) in the call settings of your smartphone.

    ※ If there is ""LTE network priority connection"" setting, pleaes check this too !!

    Or, because of the memory cleaning function of the smartphone or the installed memory cleaning app, there is a phenomenon that the app stops and does not run properly.

    Please exclude the WhoWho app among the memory cleanup apps ' cleanup categories, and then try running the app again.
