# LTEcellSearch on ADALM PLUTO error

Im following the example from Matlab in here https://www.youtube.com/watch?v=lcCWTnmKblE im trying to capture an LTE frame and decode the cell id, however i get a false PCI and it changes value everytime i run the simulation, from my phone i could see that the dominant PCI in my position is 150 and it doesnt change, why im getting different results on my simulation? here is my code

clear;clc;
rx=sdrrx("Pluto");
rx.OutputDataType="Double";
rx.CenterFrequency = 2650e6;
rx.BasebandSampleRate= 30720000;
