Whether you drop your new phone or accidentally drop it in the toilet or sink, it never ends up good. There is not really anything you can buy to protect your phone from water damage so be careful when you are in a bathroom by not keeping it in your pockets. If you can, keep it in your purse or set it down. There are ways to protect in from drops, however. There used to be one kind of case for all phones because when phones first came out, they were all the same. They were a soft layer of leather that went over your phone. Now, cases are hard plastic or silicone and do a much better job of protecting your phone.
Screen protectors are also a good item to buy. They are not very expensive and can be purchased in the store that you bought your phone or mp3 player. Since most phones these days are touch screen and cases only cover certain parts of your phone and not the screen, it is a good idea to have something protecting that part so that it does not get scratched up. What is that point of having a phone if you cannot see what you are doing on it?
There are not always issues with just the look of the phone. If you have a smart phone or a phone that can use the internet, which is pretty much every phone out there now, it is best to have a software downloaded that can keep the viruses away, because that can happen and your phone would be useless at that point. If your phone starts acting weird, check to make sure there are no viruses and if it starts getting slow, you may need to delete some downloads if you have too many to give your phone more memory space.
