As per your query, we want to inform you that 5G network service may not be available depending on the network conditions of your mobile network service provider even though you are in the 5G service area.
Regarding this, the mobile network service provider will continuously improve the network quality of 5G service through gradual network coverage expansion going forward. And, the 5G devices use in conjunction with LTE and 5G networks and support the high-speed processing of large data, which may result in increased battery consumption and higher heat generation compared to LTE devices under the same conditions.
Also, when you use applications that require more power for extended periods, the device may heat up due to increased battery consumption as well. If the 5G device heats up to a specific temperature during use, the algorithm to prevent the device’s overheating operates, and accordingly, the maximum performance of the device may be limited and the network signal changes to a 4G network.
This is a normal operating condition to assure continuous device performance.
In this case, please wait for the device to get cool down for a while and then use the device again. If the 5G device gets cooled down to a specific temperature, the device will connect to the 5G network again.
If the devices fails to connect to 5g in all the conditions, kindly reach out to us with an error report via Samsung member application. Kindly get back to us with additional information- Error log file, video, or screen-shots. This will help us to further investigate and resolve your concern.
Please share the device log file within 15 minutes of the issue occurrence by using the error report option via the Samsung Member application. To share a log file, click on Samsung Members Application > Support>> Type your issue>> Tap on error report >> Tap on send.
Note: To ensure relevant log information is included in the error report, submit the report within 3 minutes of encountering the bug or error, and do not terminate (swipe away) the Samsung Members application until you are notified that the report has been sent. This can take up to 5 minutes.
