    1. Hi Kyat Pha,
      Thanks for coming.
      Try to check whether your Gallery app has been disabled by default. When the Gallery is disabled you can't use Camera app to access your photos. To check it, go to the Settings> tap "More" tab> tap "Application manager"> swipe the screen to the right until you see "Disabled" or "Turned off" tab and then see if the Gallery is listed there, if so, tap the Gallery app then tap "Enable" or "Turned on" button. This will enable the Gallery app again and bring it back to the Apps menu.
