I’ve got bad news for you. Dropping your phone in a puddle of water, bath, sink, toilet – even getting caught in a heavy shower – will leave it irreparably damaged. The same goes for tablet computers. No more apps, games, Facebook, phonecalls or browsing. All gone. That is, if you leave it switched on. Switching it off right away is probably the best solution, but it’s not all bad news. In fact, there are a number of ways in which you can stop your phone or tablet computer from being left as nothing more than an expensive brick following prolonged contact with water.
