What are the main differences in the build quality and materials used in the Aquos R9 pro and the Kyocera DuraForce PRO 3

Build Quality

Aquos R9 Pro:
- The R9 Pro is constructed with a focus on sleek design and advanced technology. It features a reinforced aluminum frame which contributes to its overall durability while maintaining a lightweight feel (approximately 166g) [1][3].
- It is designed to meet IPX5/IPX8/IP6X standards for water and dust resistance, allowing it to withstand immersion in water up to 1.5 meters for 30 minutes [1][5].
- The phone also adheres to MIL-STD-810H standards for shock resistance, ensuring it can handle everyday drops and impacts [1][5].

Kyocera DuraForce Pro 3:
- In contrast, the DuraForce Pro 3 is built with a rugged design aimed at extreme conditions. It boasts a thicker build (weighing about 237g) and is designed to withstand rough handling, making it suitable for construction or outdoor work environments [2][4].
- This model also meets MIL-STD-810H standards for durability, being tested against drops from up to 1.5 meters, as well as having an IP68 rating, which provides enhanced protection against dust and water [2][4][6].
- The screen is protected by Gorilla Glass Victus with DX+, which offers superior scratch resistance compared to standard glass, making it more suitable for outdoor use [2][4].

Materials Used

Aquos R9 Pro:
- The materials used in the R9 Pro include high-grade aluminum for the frame and glass for the display, specifically a Pro IGZO OLED screen, which supports vibrant colors and high refresh rates [1][3].
- The device's design incorporates advanced heat dissipation technology, featuring an internal vapor chamber that helps manage temperature during intensive tasks [1].

Kyocera DuraForce Pro 3:
- The DuraForce Pro 3 utilizes a combination of rugged plastics and metals in its construction, emphasizing durability over aesthetics. Its thicker body allows for a removable battery and additional rugged features like programmable buttons and lanyard attachment points [2][4].
- The display technology includes an OLED screen that is optimized for visibility outdoors, although it may not match the color vibrancy of the R9 Pro's display [2][4].

In summary, while both smartphones emphasize durability, the Aquos R9 Pro leans towards a sophisticated design with advanced features suited for everyday use and multimedia consumption. In contrast, the Kyocera DuraForce Pro 3 prioritizes ruggedness and functionality for users in demanding environments.
