For the most part, however, Sony warns you about the limits of its non-waterproof and waterproof phones. A case in point is the company’s Xperia M4 Aqua. The waterproof camera phone for everyone has this under the fine print. You should not put the device completely underwater or expose to seawater, chlorinated water, or liquids such as drinks. Abuse /or improper use of the device will invalidate the warranty. The impact on you at home: If you have an Xperia waterproof phone. You should heed Sony’s warning even if you’ve previously taken underwater shots with your phone. Should it get damaged during such an excursion. Sony could refuse to help and point to its support materials that warn against taking them into the water. Sure, it has tons of marketing materials encouraging the opposite, but take the images with a grain of salt.
