[URGENT!!!!!] Please help me! I'm dying! moto g xt1033 call bug. topic

On my xt1033(Asian firmware), I installed Brazil 4.4.4 firmware and installed 5.0 soak test. I was having call problems. The volume of call was very low. The other person couldn't hear me clearly. Then I reverted back to Asia 4.4.4. Same problem with screen glitches. Then, I installed gpe ROM and installed 5.0.1 update. Same problem persisted. Now I'm back to 4.4.4 Asia. Save problem still there. What can I so to solve this problem? Can anyone help me.
