402SH / SHARP
With a large frameless screen,
The emotion remains intact.
We will end support for the communication encryption methods "TLS1.0" and "TLS1.1" used for software updates on November 30, 2024.
With this model, if the device is used for a long period of time without being restarted, it has been confirmed that in rare cases the device may be unable to connect to emergency numbers (110, 118, 119). This issue is being fixed with the latest software.
After support for "TLS1.0" and "TLS1.1" ends, it will no longer be possible to update the software on your device. If you have not yet updated to the latest software, please do so by November 30, 2024.
To check your software version, go to Settings > About phone and check the build number.
For details on software updates, please see here.

Software updates require sufficient free space in the device's storage. If there is not enough free space, delete unnecessary data to free up space.

This product [AQUOS CRYSTAL Y 402SH] complies with the technical standards regarding the human body absorption of radio waves established by the government and international guidelines for radio wave protection.
This product is 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 [AQUOS CRYSTAL Y 402SH] at the side of the head is 0.523 W/kg, and the maximum SAR value when worn on the body *2 is 0.425 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 to the base station, the lower the output of the mobile phone.
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."
