*1 When the USIM card/SD card tray is tightly closed, the device has IPX5, IPX8, and IPX9 waterproof performance and IP6X dustproof performance. Operation under all conditions in the actual usage environment is not guaranteed. Also, there is no guarantee that the product will not be damaged or malfunction.
[IPX5] This means that the phone can still function even when exposed to a water jet from any direction, using a water nozzle with an inner diameter of 6.3 mm, spraying water at a rate of approximately 12.5 liters per minute from a distance of approximately 3 m for at least 3 minutes.
[IPX8] This means that the phone will continue to function as a phone even if it is gently submerged in a tank of still tap water at room temperature to a depth of 1.5m and left at the bottom for approximately 30 minutes without water getting into the phone.
[IPX9] This means that the phone can still function after being sprayed with 80°C water at high pressure from four angles (0°, 30°, 60°, 90°) for 30 seconds (2 minutes) at each direction.
[IP6X] This means that the phone has the ability to prevent dust from entering the interior after being placed in an apparatus filled with dust particles with a diameter of 75 μm or less for 8 hours and then removed.
*2 Regarding compliance with military standards, testing was conducted in the nubia lab environment in accordance with 18 items of the US Department of Defense procurement standard (MIL-STD-810H). However, this does not guarantee operation under all conditions in an actual usage environment, nor does it guarantee that the product will be free from damage or malfunction.

Specific Absorption Rate (SAR) for mobile phones
This model [nubia S2] mobile phone complies with the national technical standards and international guidelines regarding the human body absorption of radio waves.
This mobile phone is designed to comply with the government's technical standards (*1) regarding human absorption of radio waves, as well as the radio wave protection limits recommended by equivalent international guidelines. These international guidelines were set out by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), which is in collaboration with the World Health Organization (WHO), and the permissible limits include a substantial safety margin designed to assure the safety of all users, regardless of age or health condition.
National technical standards and international guidelines specify the permissible value for radio wave protection as the Specific Absorption Rate (SAR), which indicates the average amount of radio wave energy absorbed by the human body, and the permissible SAR value for mobile phones is 2.0 W/kg. The maximum SAR value for this mobile phone when tested on the side of the head is 1.992 W/kg (*2), and the maximum SAR value when worn on the body is 1.618 W/kg (*2). While SAR values may vary slightly between individual products, all of them meet the permissible values.
Mobile phones are designed to transmit at the minimum power required for communication with a mobile phone base station, so the SAR value is usually lower when you are actually making a call.
This mobile phone can be used in positions other than at the temple. Please use an accessory such as a carrying case to keep the phone at least 0.5 cm away from your body, with no metal parts between the phone and your body. This has confirmed that this mobile phone complies with national technical regulations and international guidelines for radio wave protection.
The World Health Organization has stated that "numerous studies have been conducted over the past 20 years to assess whether mobile phones pose a potential health risk. To date, no adverse health effects have been established as being caused by mobile phone use."
