If you're on Verizon Live Rider from android central posted this potential fix. It's almost completely eliminated my static.
" IVE DONE IT!!!!!! IVE FIXED IT!!!!! I felt every bit of anger and disgust as all of you OMFG im disappointed with LG customer services and this is the last LG electronic device I shall purchase in my life again... SOLUTION!!!!!!!!!!!!!!!! Verizon Wireless Only from your dial pad type this in ##PROGRAM980 then press Send or Call. It will ask for a service key, the code is 000000 and after you type it in a menu will pop up, select FIELD TESTS, THEN SCROLL DOWN TO VOICE SO. I chose 13 QCELP and its crystal clear, but it can vary depending where you live, TRY ALL 3 before you stop. YOU MUST POWER CYCLE DEVICE AFTER SELECTION EACH TIME. As stated the 13QCELP is so clear for me its like a new phone. OMFG WAIT.. THIS IS A NEW PHONE, MY 3RD IN 4 DAYS. Agaain please try each of them before settling there is 3 options. EVRC Software in this device seems to have software issues in my opinion. But in your area it could be better than 13 QCELP."
