(2) Can we carry such phones inside the washroom which have Qur’an apps (although the apps are not on)?
(3) My phone plays the adhan at the time of salah. Is it a sin to turn it off if I am in a meeting?

(1) Yes, you may keep but if there is fear of disrespect then it is better not to keep.
(2) If the apps are closed then there is no harm in taking it to toilet.
(3) It is not a sin.
Allah knows Best!
