*1 Varies depending on radio wave conditions and usage environment.
*2 We do not guarantee that all commercially available memory cards will work.
*3 The communication speeds listed are the maximum values based on technical standards and are based on a best-effort approach, and are not guaranteed as effective speeds. Communication speeds may vary depending on the communication environment and congestion. Maximum communication speeds also vary depending on the area you use. *The service area with a maximum download speed of 112.5 Mbps is available in major cities across the country. Click here for details on the area.
*4 Supports UDC (Uplink Data Compression). By improving the efficiency of upstream data transmission, data transmission speeds faster than the listed speed may be possible depending on your environment.
*5 When changing models, you may not be able to continue using the email address used on your previous model.
*6 [IPX5] The phone will maintain its functionality even when it is sprayed directly from any direction with room temperature tap water at a rate of 12.5 liters per minute from a distance of about 3 m using a nozzle with an inner diameter of 6.3 mm. [IPX7] The phone will maintain its functionality even when it is submerged in a tank of room temperature tap water at a depth of 1 m and left on the bottom for about 30 minutes. [IP5X] This means that the phone will function and remain safe when it is placed in a device containing dust particles with a diameter of 75 μm or less for 8 hours and agitated, and then removed.
*7 For models that do not come with an AC adapter, a separate AC adapter (1.0A or 1.8A, [MediaPad M1 8.0] only supports 1.8A) is available. For details, please check with Y!mobile shop or Y!mobile dealer.

Update information

About Specific Absorption Rate (SAR)

This product has been designed to comply with the technical standards ^*1 set by the government regarding the human absorption of radio waves, as well as the radio wave protection limits recommended by equivalent international guidelines. These international guidelines were established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), which is in collaboration with the World Health Organization (WHO), and the limits include a sufficient safety margin for all users, regardless of their age or health condition.
National technical standards and international guidelines define the permissible value for radio wave protection as the Specific Absorption Rate (SAR), which represents 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 product [Android One S4] at the side of the head is 0.822 W/kg, and when worn on the body ^*2 the maximum SAR value is 0.423 W/kg ^*3. Although there may be slight differences in SAR depending on the individual product, all of them meet the allowable value. Mobile phones are designed to have the minimum transmission power required for communication with mobile phone base stations, so when actually making a call, the SAR value is usually smaller. In general, the closer the distance from the base station, the lower the output of the mobile phone.

*1 Technical standards are stipulated in the Radio Law-related Ministerial Ordinance (Article 14-2 of the Radio Equipment Regulations).
*2 This product can be used in positions other than on the side of the head. By using accessories such as a carrying case to keep the device at least 1.5 cm away from the body and without any metal (parts) between the device and the body, this product complies with national technical standards and international guidelines for radio wave protection.
*3 This value is the value for simultaneous transmission.

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."
