Missed calls notification

Hi guys,

I only got 1+2 just a day back and am still trying to set it up.. So please bear with me..

If my phone is locked and i get some voice call which i didn't answer, then it is treating it as missed call.

But when my phone is unlocked and get voice call which i didn't answer, 1+2 is not treating as a missed call. It is treating it as received call. Is it just me ? Is there any app to treat it as missed call.

Thanks !!!

Unlocked g900p does not show missed calls- can't change voicemail number.

I have had my g900p unlocked and it works pretty well. Makes and receives calls, internet works pretty good, MMS messages work.
My only issues are I do not get any missed call notifications and I cannot find a way to change the number voicemail dials. I am also stuck on 3G but that's not a real biggie.
Is there another ROM that will help with this stuff? I am running stock 5.1 unrooted. Knox is not a worry with me :) I have no warranty.
Kthanks
