Android Question Get next alarm from Android Clock App

[Humphrey]

Hello to the forum,
I'm trying to read the next alarm time from the Android clock.
Here I found: Phone.GetSettings("next_alarm_formatted"), but since API 21 this function was deprecated. AlarmManager.getNextAlarmClock() should be used for API >= 21.
So my code is

    Dim AlarmManager As JavaObject
    Dim AlarmClockInfo As JavaObject
    Dim rf As Reflector
    Dim Context As JavaObject

    Context=rf.GetContext
    AlarmManager.InitializeStatic("android.app.AlarmManager")
    AlarmClockInfo.InitializeStatic("android.app.AlarmManager.AlarmClockInfo")
    AlarmManager = Context.RunMethod("getSystemService",Array As Object("alarm"))
    AlarmClockInfo = AlarmManager.RunMethod("getNextAlarmClock", Null)
    If AlarmClockInfo.IsInitialized Then
        Dim Alarm As Long = AlarmClockInfo.RunMethod("getTriggerTime", Null)
        TLabel.Text = DateTime.Time(Alarm)
    End If

When I run this code on my Samsung A6, the read Alarm time is always off by 5 minutes:
Alarm set to: 6:00
Alarm read: 5:55:01

On stackoverflow I found, that this is a bug of the Samsung clock app.
The app SleepClock from Allessandro71 shows the same problem on my phone.

Does anyone have a solution for that problem?

If the code works correctly on non-samsung phones, then you may be able to simply detect if the phone is made by samsung, and if so, then compensate for the 5 mins on just those devices.

Here's some sample code to determine if the device is made by samsung:

Dim p As Phone
If p.Manufacturer.ToLowerCase = "samsung" Then
    Log("This is a Samsung device.")
    ' Your code for Samsung devices here
Else
    Log("This is not a Samsung device.")
    ' Your code for other devices here
End If

The app SleepClock from Allessandro71 shows the same problem on my phone.

on my Samsung A33 5G the alarm time is displayed correctly

Thanks for your replies, JohnC and Alessandro71.
If it's not on all Samsung phones, it's hard to find out if my function is working correctly or not.
So it's not possible to compensate for the 5 minutes.

But today I found out, that my function is also reading the next calendar alarm. This, by the way, with the correct time.
I have a reminder in my calendar for tomorrow 9:30, but no alarm clock alarm set.
My function is returning 9:30 of tomorrow.
This is what also Alessandro71's App SleepClock returns.
@Alessandro71: Is this also only on my phone, or general on all phones?
Is it possible to read only alarm clock alarms?

I'm also using Phone.GetSettings, since I never had the time to experiment with the new, non-deprecated, method
