For the people who have no sound I will tell you guys how to do this.
You grab a toothpick and start cleaning on top where the callers voice comes from. After that you take a thin needle and start poking little holes at the same location (softly) and then try it out :)
Worked like a charm for me :D
This is the best solution and it is very simple!
Hope it helped and let me know if it worked :)
- Thank you guys for more than half a million views and I am so happy that this method worked for a lot of people!
