I am reporting a critical network issue with the iQOO Neo 9 Pro. When the device is in an area with zero mobile network coverage and utilizes Wi-Fi Calling, it becomes 'stuck' once the Wi-Fi signal is lost.
After leaving the Wi-Fi range and moving back into an area where a mobile network is available, the device fails to automatically reconnect to cellular services. This leaves me with no access to calls or data indefinitely, despite being in a known coverage zone. The device does not recover the signal on its own. I have to switch off the mobile and switch it on, which is a major reliability concern.
Please investigate the modem's search triggers for when a VoWiFi session is terminated in a zero-signal environment."
