    - one thing i also started doing is indirectly ask about the idea on expert subreddits on reddit and see what people have to say

    - one of my latest ideas was to handle spam calls on my android phone

    - the way i wanted to do this is to have an app pick up the phone call automatically everytime and ask a bunch of user defined questions

    - for example, caller: hi i am angel from XYZ spam company

    - audio streams through the app with an LLM processing every word and it asks back "who are you trying to reach?"

    - caller doesnt answer in 30 seconds or wrong answer. call dropped automatically and the phone is not even ringing yet

    - caller says ABC and the autoresponder immediately asks the next question

    - "what is the password to reach abc"

    - caller doesnt answer or gives incorrect answer within 30 seconds and call is dropped immediately

    - caller gives correct answer and now the phone starts ringing

    - obviously the questions are set by the user and it ll change from user to user

    - imagine by biggest disappointment when I found out from the r/androiddev group that the permission to actually audio process a phone call is simply not available unless you root your android phone. Its a no-go even on the iphone

    - Even if you do root the phone, I haven't gotten a conclusive answer from anyone either on reddit or even here on HN so far on the feasibility of implementing such a feature

    - Thank god I did not burn 100 hrs into this

      Well… yeah… this sounds like the kind of app I wouldn’t want to have anywhere near me. Ever.

      I wouldn’t be surprised if this even broke a law or two. Sounds like a thoroughly bad idea. For all involved.

        how exactly do you propose handling spam calls then? all spam callers are using auto generated numbers. block one and they come back from another

          Do you feel obligated to open every email you get, or do you just read the ones from people you know?

            dude i get 4 calls a day from spammers and its very annoying. an email is not a phone call. you are sitting on your desk and your phone starts ringing. block a number and they come back from another

              So just have it ring only for people you know
