As per your concern, we want to inform you the mobile network service provider will improve 5G network quality through expanded coverage. 5G devices may consume more battery and generate more heat compared to LTE devices, especially when using high-power applications for extended periods. When a 5G device heats up, the algorithm may limit its performance and switch the network signal to 4G to prevent overheating.
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.

thanks for your reply Sir whenever the network switches to 4G the speed is not even as good as 2G Apart from this, we have other 4G devices which are still providing great speed. After the last update, I am facing issues in calling Samsung A55. Even after having network in the mobile, I am not able to receive or make calls. This condition happens at least once a day.
