For the past several weeks to a month, my verizon samsung droid charge has the bursts (very fast) of static during a minority of phone calls. It happens to cell and land lines. I hoped I would connect it to a battery, but I cannot, I factory reset my phone (for a different reason) but that did not help. It will happen a bunch of times in a day and then not again for days. Not sure if it has happened on bluetooth, but has happened on speaker and holding the phone. Any thoughts would be appreciated. I have not reported to verizon yet.
