Screen stops turning on using Service and WakeLock?

Question

Java

I am writing an application with a foreground service that records sounds when they are detected.
The problem is that after ~10 minutes the phone's screen only turns on with a delay of ~20 seconds (sometimes more) after I press the power (or home) button. When I manage to unlock the phone, it starts to lag. In some cases, it simply reboots while the service is running.
The service works fine even when I can't turn on the screen. You just need to deal with the problem that the phone starts to fail when the screen does not turn on for a long time.

Service code. How could I shorten it.
recorderservice:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    if (intent.getAction().equals(START_ACTION)) {
        isActive = true;
        /* создание уведомления */
        startForeground(1, notification);
       startListening();
    } else if (intent.getAction().equals(STOP_ACTION)) {
        isActive = false;
        stopForeground(true);
        stopSelf();
    }
    return START_STICKY;
}

Listener start method:

I've been suffering for a week now. When I tested other similar applications, they worked all night, even after 10 hours of work, the phone screen turned on. Tried not to use WakeLock like here ( https://stackoverflow.com/questions/54607665) but nothing changes.
Phone is Samsung Galaxy A3 2015.
Thank you
