I have bought brand new Lumia 720 two weeks back. Everything is perfect except I used to hear scratching sound while speaking. Its really irritating. Signal strength having no problem. Otherside person can hear me crystal clear. No call drop happening also. My Lumia is amber updated.
if I use headset or Bluetooth, sound is clear and crisp. I have cut the mini sim to micro sim. Is this because of sim or any hardware or software defect. Please suggest
