• The pixel value may vary in different camera modes, and is subject to actual usage.
• Please follow the official guidelines when using this feature: Do not immerse the phone in non-fresh water during use. Please shoot underwater at a maximum depth of 2 meters and use it for no more than 30 minutes at a time. After using the phone underwater and removing it from the water, press and hold the corresponding button on the screen to exit the Underwater Mode and allow the water to drain. Then place the phone in a dry, well-ventilated area to dry. Avoid charging or connecting external devices to the USB port until it is completely dry. Please note that using high-temperature heating methods, such as hair dryers, during the drying process may damage the phone. Also note that due to differences in temperature and humidity, condensation and fogging may occur in the lens when the phone is immersed in water, which can be resolved by placing the phone in a constant temperature, low humidity environment for approximately 20 minutes. Damage caused by liquid ingress due to use of this feature without following official water resistance test conditions is not covered under warranty.

• Measured diagonally, the screen size is 6.67 inches (16.94 cm) in the full rectangle. Actual display area is slightly smaller.
• Only specific apps support 120 Hz. In different apps or game interfaces, the screen refresh rate may be slightly different.
• The product has passed SGS Low Blue Light Certification under conditions with Eye Protection enabled at the setting of highest intensity. This product is not a medical device and does not have any therapeutic functions.
• This product has been tested under controlled laboratory conditions and is rated as IP68 and IP69 under IEC standard 60529-2013. IP69 water resistance test conditions: A rotation speed of (5±1) rpm, nozzle angles of 0°, 30°, 60°, and 90°, a flow rate of (15±1) L/min, a water temperature of (80±5)°C, a test time of 30s/position, and the phone placed in a vertical position with the USB port facing up. IP68 water resistance test conditions: Submerged in water up to 2 meters for up to 30 minutes, with a temperature difference between the water and the device of less than 5°C. The resistance to splashes, water, and dust is not permanent and may be reduced due to daily use. Do not charge the phone when it is wet; instead, clean and dry it immediately. Damage caused by liquid ingress is not covered by warranty.
• This product has been sampled and tested in controlled laboratory conditions to simulate life scenarios. The actual performance of the product may vary under real-world conditions. The resistance to splashes, water, and dust is not permanent and may be reduced due to daily use. Do not charge the phone when it is wet; instead, clean and dry it immediately. Damage caused by liquid ingress is not covered by warranty.
• To simulate real-life kitchen spill scenarios, multiple liquids such as ketchup, cola, milk, and hand sanitizer were used. Liquids were splashed onto the device through the bottom speaker and top microphone openings, followed by immersion to test rinseability and liquid protection performance.
• The typical battery capacity is 6000 mAh, and the rated battery capacity is 5860 mAh.
• According to tests by vivo laboratories, the battery retains at least 80% of its capacity after 1600 complete charge cycles. These tests simulate daily user habits (charging and discharging once a day) and indicate that 1600 cycles equal approximately 4 years of usage. The above data was provided by vivo's lab according to tests conducted in a simulated environment, with ambient and battery temperatures of 23°C±2°C for a full charge and discharge. Actual results may vary due to differences in test equipment, test environment, as well as personal usage patterns and habits.
• Data is obtained from vivo's laboratory tests and refers to single-app operations only. Test environment: Ambient temperature of 25°C±2°C. Test condition: the device 100% charged. Actual battery duration is subject to actual usage and may vary due to environmental and other factors.
• This product has been tested under controlled laboratory conditions. As the phone contains precision parts, please make sure not to bump or drop the phone during use. Any man-made damage to the device is not covered by the warranty. With AirSpring Technology Drop-Resistant Phone Case, Y400 has passed military grade shock resistance test (MIL- STD- 810H) conducted at the brand's laboratory in a controlled environment.
• Performance improvement data is obtained from the official Qualcomm website, which is an improvement over the previous generation Snapdragon® 680.
