The Short Answer

Electronic circuits are designed to only allow electricity to pass through certain parts at certain times. That's how your phone works. It's a set of boolean functions (1 or 0/true or false). Electricity passes through chip, and it makes a decision such as "and/or". If it's 'and', it sends the signal one way, and if it's 'or', it sends it another way. After it does that, this step is repeated through other logic gates that have other functions that aren't and/or (not/or or any of the many other variants). Once you submerge it into water, it doesn't follow this designed 'trail', and the phone short-circuits. Because water is conductive, the electrical signals go wherever they can, and electronics can't handle that. To make something of a comparison; It's the same reason you get in a line when you're shopping. Imagine if all the customers just threw all their items onto the counter at the same time and talked over each other. The cashier wouldn't know what to do. That's what the submersion is.
