S-22 Ultra Network Issue

[sher92]

I am facing issue regarding signals. When I am outside, it captures the signal of 4G/3G/2G and cellular. But when I am inside, the signals are lost. What can be issue and what will be the fix?

After detailed conversation with Chat GPT. He is saying to change the firmware.
