Purchased three different phone covers, all react with the same issues. When the cover is installed I drop calls two/three times within a 5 min conversation and the phone reacts erratically (odd beeps and chirps). People on the other end of the call say I am dropping in/out of the conversation. When I remove the cover all of the above issues disappear. Purchased a cover from my carrier, more $$, but none of the issues!!! Overstock's return policy needs review, Purchase a sub-par product and still have to pay for the return of the item, because it is now considered "used". How else would one find it is not going to work as promised unless you use it??
