Some Android phones not opening “About device” page in Settings?

Use PackageManager.resolveActivity() to check whether such an Activity exists. If that returns null, there is no activity that matches the Intent and you have to guide your customers to the settings in another way:

Intent intent = new Intent(Settings.ACTION_DEVICE_INFO_SETTINGS);
ResolveInfo resolveInfo = getPackageManager().resolveActivity(intent, 0);
if (resolveInfo == null) {
    // help customers by describing how to get to the device info settings

} else {
    startActivity(intent);
}
