System Alarm clock icon not shown

I’m developing with Android studio and I faced an issue with my Samsung mobile(s). When I set an Alarm clock programmatically, the system Alarm clock icon shown in all other test devices except for Samsung devices.
My code is (In Kotlin):
val requestCode = 1440
val tm = AllTimers.GetReminderTime()
val am: AlarmManager = context.getSystemService(Context.ALARM_SERVICE) as AlarmManager
val i: Intent = Intent(context,
i.putExtra(“Id”, 1)
val pi = PendingIntent.getBroadcast(context, requestCode, i, PendingIntent.FLAG_UPDATE_CURRENT)
val pi2 = PendingIntent.getActivity(context, requestCode, Intent(context,, PendingIntent.FLAG_UPDATE_CURRENT)

                          if (tm != null) am.setAlarmClock(AlarmManager.AlarmClockInfo(tm.time, pi2), pi) else am.cancel(pi)

What is the problem?
