Hi, For my application i need to get a unique ID of the device to make stats. So I found this **** String key(L"http://tizen.org/system/duid"); String deviceUniqueId; SystemInfo::GetValue(key, deviceUniqueId); AppLog("Device unique ID : \"%S\" ", deviceUniqueId.GetPointer()); **** And the result is "Device unique ID : "2.2ERROR" " I tried on another phone but it give me the same result Is anyone having the same issue or is it just me ? If you have another way to get a unique ID of the device, i'll take it. Thanks,
