Change UUID in BeaconRegion not reflecting

[dileepjb2]

I have one existing UUID with X name I changed UUID with Y name. but it is not reflecting only in one android device and reflecting in other devices. I cleared cache removed Bluetooth storage, Bluetooth cache still no luck. Any idea what i need to change.

let beaconRegion = this.ibeacon.BeaconRegion(
'deskBeacon',
X );

to

let beaconRegion = this.ibeacon.BeaconRegion(
'deskBeacon',
Y);

Thanks in advance
