Why would you go grabbing your phone and shit in an injection... IDK personally.. I like to keep touching other shit to minimal. in and out. Takes a few secs. I take every precaution. I'm not ending up in an ER. Phones are dirtier then toilet bowls.
it was allready in and aspired i just need to get the stuff in and pull out no touching of the site or needle.....i do a very intense site prep
