Ensure your APN settings are correct. Some 2021 updates reset custom APNs back to default carrier profiles, which might lack 5G permissions.
Bug fixes resolved intermittent drops on the 5.2 GHz Wi-Fi band when multiple devices connected simultaneously. Carrier-Branded vs. Global Generic Firmware
Incorrect flashing techniques using Qualcomm service tools can erase the device's NVRAM, wiping out the IMEI number and destroying cellular connectivity.
