No Calls or Messages
Be it sending or receiving, the phone is incapable of anything related to text messages or calls.
Text messages show as Not Delivered. When trying to make a call, the call screen is quickly flashed and the phone returns to the same menu.
Replaced the screen some time ago, but not the source of the problem, as the phone did not stop sending/receiving calls/texts after it. Later on replaced top microphone. Not sure if it was the cause, but it's the last known modification since it was working properly. Worth mentioning is that although the signal indicator seems to work properly when set up through numbers, when shown through bars, will always show none at all or, when turning on, will show 2 or 3 for a short period of time and reverse to showing none at all. Interesting as well is that Mobile data works perfectly fine.

This... this is absurd. This doesn't make any &&^&^$^ sense. What, does the freakin phone just stop working for no reason outta nowhere?
Please, any tips are appreciated, I don't know what else to do. Could try replacing the top piece with the microphone and the buttons, but come on, where the !&&* is the link between the two?
Is this a good question?
