Root cause:

From Android N OnePlus introduced a feature similar to Mi devices which prevent certain apps from auto-starting after reboot. I suspect that same feature is preventing your app to receive BroadcastReceiver as well.

Solution

Use AccessibilityService service in your app and ask user to turn on AccessibilityService for your app from Settings and boing doing this BroadcastReceiver in your app will work as expected.

Since AccessibilityService is a system level service, so by registering your own service you are passing the certain filter applied by these manufacturers and as soon as your custom AccessibilityService gets triggered by the OS, your app becomes active in receiving the eligible BroadcastReceiver that you had registered.

Here is how you can register your own AccessibilityService.

Create your custom AccessibilityService

public class MyAccessibilityService extends AccessibilityService {

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {//do nothing }

    @Override
    public void onInterrupt() { //do nothing}
}

Create configuration file my_accessibility_service.xml and add below code:

Add permission to AndroidManifest.xml file:

Add your AccessibilityService in AndroidManifest.xml file:

You done!

Below is method to check status of AccessibilityService:

private static final int ACCESSIBILITY_ENABLED = 1;

public static boolean isAccessibilitySettingsOn(Context context) {
    int accessibilityEnabled = 0;
    final String service = context.getPackageName() + "/" + MyAccessibilityService.class.getCanonicalName();
    try {
        accessibilityEnabled = Settings.Secure.getInt(
                context.getApplicationContext().getContentResolver(),
                android.provider.Settings.Secure.ACCESSIBILITY_ENABLED);
    } catch (Settings.SettingNotFoundException e) {
        Log.e("AU", "Error finding setting, default accessibility to not found: "
                + e.getMessage());
    }
    TextUtils.SimpleStringSplitter mStringColonSplitter = new TextUtils.SimpleStringSplitter(':');

    if (accessibilityEnabled == ACCESSIBILITY_ENABLED) {
        String settingValue = Settings.Secure.getString(
                context.getApplicationContext().getContentResolver(),
                Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES);
        if (settingValue != null) {
            mStringColonSplitter.setString(settingValue);
            while (mStringColonSplitter.hasNext()) {
                String accessibilityService = mStringColonSplitter.next();

                if (accessibilityService.equalsIgnoreCase(service)) {
                    return true;
                }
            }
        }
    }

    return false;
}

Note: I have not tried but it may help.
