Issue in SM-G950F(Samsung s8) for running OneoffTask

I am facing an issue, where my app users cannot get past a point.

When the user tries to login, it gets logged in, but after that I hit an API with "OneoffTask" using this code :

OneoffTask task = new OneoffTask.Builder()
        .setService(SyncService.class)
        .setTag(TaskConstants.UPLOAD_STREAK)
        .setExecutionWindow(0L, 200)
        .setRequiredNetwork(Task.NETWORK_STATE_CONNECTED)
        .setPersisted(true)
        .setUpdateCurrent(true)
        .build();

GcmNetworkManager mGcmNetworkManager = GcmNetworkManager.getInstance(MainApplication.getContext());
mGcmNetworkManager.schedule(task);

This code is executed, but the scheduled task does not execute. samsung s8 model : SM-G950F. It is working on all other devices. Why is this issue, I am also not getting an error. It is just stuck there.
