Don't know how to update programs/applications (Android)

1. Open Google Play (store) -> Tap on the three-vertical-line button in the upper left corner of the screen -> My apps and Games
   
   

           
   
   

2.   Tap the Update All button if you wish to update them all at the same time, or you can update them one by one by tapping on an application and pressing Update
   
   

       
   
   

Note: Connect your mobile device to a stable Wi-Fi network before updating the application in order to avoid additional charges, shorten the updating time, and to ensure that the downloaded updates won't be corrupted.

You may also enable automatic updating of apps in the Google Play Settings. You can select to update them via Wi-Fi only, or via Wi-Fi and/or mobile data.
