Sony’s ratcheted up its water-resistant device tech a notch with the launch of the Xperia ZR, a new 4.6-inch, 720p Android smartphone that’s waterproof to 1.5 meters (5 feet). Sony boasts that its new device will let you film your snorkeling adventures in full HD quality, with HDR in both video or 13-megapixel stills thanks to the Exmor RS image sensor — there’s also a dedicated camera button like the one on the Xperia ZL. The handset packs a Snapdragon S4 Pro quad-core 1.5GH CPU, 2GB RAM, LTE, NFC, Sony’s Walkman album and movie apps and a notable OptiContrast OLED screen with Bravia tech to reduce glare “even in bright sunlight.” There’s no word yet on pricing or availability, but as soon as we hear more, we’ll try to prep you ahead of that next beach-bound holiday. Meanwhile, you can check the galleries, PR and video after the break for more. Update: As Xperia Blog found out, the Xperia ZR is actually the international version of Japan’s upcoming Xperia A SO-04E — the one we saw popping up in the FCC database.
