I bought a Note 4 delivered from HK from Lazada. How do I know whether it is a imitation. There are spelling mistake on the screen protector 'carema' and 'selact' and these the Samsung Codes don't work:-

*#0289# [Melody Test Mode]
*#03# [NAND Flash S/N]
*#0588# [Proximity Sensor Test Mode]
*#0589# [Light Sensor Test Mode]
*#0673# [Audio Test Mode]
*#07# [Test History]
*#0782# [Real Time Clock Test]
*#0842# [Vibra Motor Test Mode]
*#12580*369# [SW & HW Info]
*#1575# [GPS Control Menu]
*#2263# [RF Band Selection]
*#232331# [Bluetooth Test Mode]
*#232337# [Bluetooth Address]
*#232338# [WLAN MAC Address]
*#232339# [WLAN Test Mode]

When I Googled the Build Number it refers to Nexus 5.
When I check the imei number fromwww.emai.info it did say Note 4
