Can I bring and use a tablet or e-reader in a beis hakise for reading news or other non-torah topics even if there are shiurim and torah mp3s and PDFs stored on the same device. Obviously, I do not open files related to Torah in that makom.
Answer:
There is no problem in using a tablet etc. in a bathroom.
The presence of shiurim in the memory of the tablet does not give it any kedusha, because these shiurim are not “actually present” as written words. Only a written Torah text has kedushah, whereas electronically encoded text has no holiness at all.
Best wishes.
