I have a Samsung Galaxy S7. I have been using the "Block Calls" feature on my phone. But the calls are STILL ringing through. I thought that this feature stopped the calls from ringing and sent them directly to voicemail. I am frustrated because these stupid calls ring while I am at work, but it is a requirement that I have to have my cell phone on. I have been using the Do Not Disturb feature but sometimes there are calls I actually need to take, but are not on my favorites list. Which is how my Do Not Disturb feature has been customized. Please help. I am at my wits end right now.
