“And its not true you cant use the phone on shabbos, You can use it for an emergency”
So in case of an emergency, you can open the siddur app on Shabbos?
And you’ve seen that done?
Because the poster was talking about, using the siddur app on the phone.
And as far as the phone being ossur in case of emergency, that is dependent on whether Shabbos is hutrah or hudcha.
