Gavra, the Chazon Ish (top of the page) is hard to read on hebrewbooks, so I’ll quote (I have the sefer in front of me) – he refuted the tayna of an umbrella being ohel, says it might be tikun mana, then says:
??? ????? ????? ??? ????? ?? ????? ???? ????? ????, ???? ???? ???? ???? ????? ??? ????, ???? ???? ???? ?????? ????? ??? ????? ?????, ??? ???? ???? ?????? ???? ?????, ?? ?? ??? ??? ???? ???????
I think we can agree that R’ Shmuel Auerbach shlit”a is correct that he would say the same about use of cell phones (transporting it for the alarm clock function) and that kol shekein v’kol shekein for texting, even if there were a way to get around koseiv and tikun mana.
that horse has left the barn quite a while back
Should that change my approach or yours?
