Idk it was ok everytime but for some days while i use it for singing, the mic doesn't work, that's why my voice becomes mute at the time of playing back, it's not my mic prblm, nor earphones prblm also, cz i use earphones or headphones while calling, so it's definitely this app's prblm, so plz fix it quickly, i will give it 5 stars as it is fixed
