Have you ever been asked, or ever wondered, âIs refrigerant, especially R-134a, heavier than air?â. Just this week I was asked this very question. Thinking I knew the answer right away, I was able to contain my natural, blurt-it-out style of an answer, at least until now.
Add a Contact to the Blocked List. Block someone from calling or texting you one of two ways: 1  To block someone who has been added to your phone's Contacts, go to. 2  The All Contacts window will appear where you can scroll through names to then tap the name of the contact you'd like to block.
So I have to add someone to contacts to block them? Not if theyâve recently called or texted you. Looking at a text message thread, for example, you can simply access a personâs contact card through the lowercase âiâ in a circle icon. Look for the block option at the bottom of the page. Likewise, you can bring up the contact info for anyone in your recent calls list.
