First, read the English article below.

It's fairly simple to block a number on your iPhone. You simply need to add numbers to a block list through your phone's settings.  There should be a small "i" icon next to every number on your contact's list. Tap this number next to the contact you want to block. Scroll to the bottom of the screen and click "Block this Caller." Tap to block the contact. If you have a newer android model, it's fairly easy to block calls. Simply go your settings, then call, and then call rejection. From here, you can enter a number of contact who you wish to block. If you have a Samsung phone, you can block incoming calls for a set period of time by going to your settings. Go to Call Settings, My Device, Blocking Mode, and then Disable incoming calls. You can allow calls from certain contacts to go through as an exception. 

Now, please write a short abstract for it in Indonesian. Abstract:
