JP Brother about the Changing Preferred Network Type from the 4636 (phone info) setting. Even if I switch it to the NR only the network stops, the signal bars disappear AND,
IF i change it to NR and LTE, it still uses the same 4G data while showing the 5G sign. And about the JIO.
Let me tell you, i have jio sim too. But Here I have multiple devices (other phones) with Airtel ISP.
None of the other devices facing the issue who uses airtel, why Iām the only one? (None of the person who uses airtel and living with me in the room face the issue.)
I have also tried Transferring my sim in the other devices, It works properly and then again in the CMF 1 itās working on 4G data even when showing 5G.
See this. This is one my todayās data end issue.

Check the time in image for better understanding.
(I have also reported this to Airtel too. ) This was the issue i was facing in OS 3.0 and then it was solved. But itās back in OS 4.0.
I have tried everything from a year. Then posting this.
See this too the 5G NSA gets disconnected. (Previously the Smart 5G option helped the connection by keeping it disabled. The new nothing update making it enabled automatically.) Also I have 5G standalone enabled.

Jio is the only operator in India using the ālow-bandā 700 MHz (n28) spectrum for 5G, which provides superior indoor coverage. Airtel focuses on āmid-bandā frequencies like 1800 MHz and 2100 MHz for its 5G rollout. So Other phones support the Airtel 5G just not the CMF 1? Really?
Even if it is using 4G, why show the 5G sign? Thatās an issue too.
