What should I do if the in-built applications of my device do not work?
a) Clear the cache of the inbuilt app.
To clear an app’s cache: go to main menu->select “Settings”->“Apps”->select “VIEW ALL ×× APPS”->select the app from the app list->select “Storage & cache”->select “CLEAR DATA’ and “CLEAR CACHE”.
b) Check if a third-party app with similar features is installed. If yes, please uninstall the third-party app.
c) Update app to the latest version from Play store for better compatibility.
d) Try to reset or update your device. (Refer to “How can I perform a factory reset on my device in the Back Up & Reset module” & “How can I upgrade my device in the Basic Settings module”).
If the previously described options do not help, you can contact our hotline or repair center to get more professional technical assistance. Find the hotline or repair center information from the official website or APP “Support Center”.
Note: Available settings and menus may vary depending on device model and software version.
