Last week my girlfriend dropped my phone in a cup of water by accident. She dropped it and tried catching it and knocked it right into the cup. It only had a few ounces of h2o in it but my phone started acting up. I turned it off for 24hours and set it in rice to get all the moisture out. I turned it on and it is working perfect now. I looked at both water damage stickers and they are still white. Should I go ahead and make up some reason and return it anyways since it did get wet and might start corroding and give me problems later on?
