So the other night I was out and my battery was running low. I was around 12%. I previously made a call around 10:10. The phone worked normally, it rang and such but no one picked up. Around 15mins later I used the phone again to call my dad. There was no sound from the ear piece. But I looked at the screen and it shows my dad picked up. I tried to tell him, I'll call him back. But apparently he couldn't hear me so he kept calling me. I answered the call but no sound was coming out of the ear piece and the mic wasn't sending my voice to him. I tried to call my friend who was with me and the same happened. I turned off the phone and turned it on again and it works properly. Has this happen to anyone? This was the first time occurring. I'm on the 2.1 leak.
