Moto-G Noise Issue

[creeker2]

I have a MOTO-G that has excessive background noise on the receiving end. My wife has the same phone with no problem. I called motorola warranty replacement two times and they told me my phone was rooted and therefore the warranty is void. However I have run many different root checker apps and they tell me my phone is not rooted. HELP!. Thank you in advance

Have you tried removing the sim card and blowing out the slot, wiping off the sim with a clean cloth, all while the phone is completely off and powered off, then replace the sim and turn the phone back on? If this is a cut sim in an adapter you'd probably want to get a new one of the correct size.
