iPhone 12 Earpiece Suddenly Stopped Working

Hello guys, so last night my friend and I were on a video call on WhatsApp, and when I left the call, the earpiece of my iPhone 12 randomly stopped working. It’s not because of dust covering the speaker, as I already cleaned it, and it still doesn’t work. It’s not low or muffled—it just completely stopped working. I tried all the methods on YouTube and other solutions like updating, reset but nothing worked. (it not only happen on the whatapp)
