Hate sand getting in your headphones and charging ports whenever you go to the beach? A tip on Reddit suggests applying a large piece of cling wrap onto the touchscreen and then wrapping it around to the back so that all ports are covered.

The touchscreen should still work, and you shouldn't have overheating issues unless you keep it wrapped up all day. Keep in mind that this process does not make your phone waterproof, so if you plan on getting wet, you may want to put your phone in a freezer bag instead. The disadvantage of using freezer bags is that many people will take their phone out of the freezer bag a few times for texting or whatnot, and that is when sand gets in the device. You could always do both, but then you'd probably have to worry more about overheating.
