Oppo is on a smartphone release streak. The company has been launching new devices just about every second month. Its newest budget smartphone to launch is the Oppo Reno A which was launched today in Japan. The Reno A comes with a 6.4-inch AMOLED display with a FullHD+ resolution. Powering the device is the tried and tested Snapdragon 710 processor coupled with 6GB RAM and 128GB storage . Oppo's budget-oriented device has a decent 3600mAh battery which should get you through a day of use on a single charge. What's even more interesting is that the device comes with an IP67 water and dust resistant rating. It's still rare to see budget smartphones to have an official Ingress Protection rating so kudos to Oppo. On the rear, we get dual rear cameras.

The Pixel 4 and 4 XL start at a price of  $799 and  $899 respectively and you might be wondering whether or not the Pixel 4 duo is waterproof. Well, you can ease your mind since the new flagship devices from Google indeed have an IP68 dust and water resistance rating. This means that the Pixel 4 duo should be able to survive being submerged under 1.5m of water for 30 minutes . Of course, it's worth noting that an Ingress Protection rating does not always guarantee that the device would always survive being submerged in water or exposed to dust. Nonetheless, while we weren't surprised by the specifications and features on the latest Pixel duo, what surprised is that the Pixel 4 duo would not be brought over to India. It seems Google has decided to skip one of the largest...
