Does anyone know how to access the hidden dialer engineering screen? I'm looking for the downlink and uplink channels to plug into the EARFCN card in the app LTE Discovery. Looking online has rendered nothing for this phone and it says the procedure can be ROM specific.
Not sure of this is what your looking for but try this.

And don't forget the ##3282# code also. Just punch them in the dialer
