Other than being waterproof, they are also often shock-resistant making them ideal for outdoor activities, whether business related or not.|
Most will have undergone stringent IP68 tests to ensure that they meet military-specified standards for protection against vibration, shock, extreme temperatures, dust and water.
Now, I want to share you some FEATURES I want to emphasized in making a rugged phone, Screen size: 5.7-inch | CPU: Snapdragon 635 | RAM: 6GB | ROM: 128GB | Battery: 8000mAh | Fast charging | Rear camera: 16+13MP | Front camera: 21MP. My personal reasons why I choose 5.7inch is that I really handle it very easy, the 6GB RAM and 128GB because a person like me who like surfing, gaming and all day socializing, this is so perfect. The capacity of battery is 8000mAh because I believe, the more battery life, the happier. I thing the MP of its camera is perfect for everyone especially to me who really likes photography.
Regarding to its STRUCTURE, I want it to be liked a combination of rubber, metal and titanium alloy in a two layer structure.
