Samsung need to update the network Same issue on my S24+ bought 2 months back while heating and in some normal scenario network fluctuations from 5G to 4G
As per your concern, we want to inform you that while 5G devices work with both LTE and 5G networks, they may consume more battery and generate more heat compared to LTE devices. High-speed processing for heavy data can lead to increased energy usage and device heating. If your device gets too hot, our safety algorithm may limit performance and switch to 4G temporarily to prevent overheating. This is normal and helps maintain 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.
However, please perform the below-mentioned troubleshooting steps, these may help in resolving your concerns.
If the issue persists, kindly report the problems with a log file. To share a log file, click on the Samsung Members Application (Open Samsung Members Application > Support> Tap on send feedback> Choose Composer> Select error report> select the appropriate issue category> Type your query and send).
I have did all the steps shown in the video linked, I have also tried using the light performance mode and bypass charging I got 45w pd charger from samsung still overheating and switching to 4g.
device does connect to 5g after it's cooled down.
But I can't update or install games file because of the heating and network switching issue so please push some optimization update (I am also upto date with update still the issue)
