What does represent the VINCE codename for the Redmi 5 ?
Sorry for my English.
Every android device has a specific codename assigned to it by the OEM (Original Equipment Manufacturer).
The codename assigned to the Redmi 5 Plus is vince.
The codename helps differentiate between phones with different internals because sometimes the real names of the device are not clear or are too long to be used in coding the firmwares. The Xiaomi Redmi 5 Plus is a long name with several spaces and cannot be used in coding of firmware. So a shorter name is assigned. Then there is the confusion that is sometimes present in names of the phone. The Redmi 5 Plus in China is being sold as the Redmi Note 5 in India. But in China there is another device being sold by the name of Redmi Note 5. The indian and Chinese Note 5 are completely different and so have different codenames. But as the Chinese 5 Plus is the same as Indian Note 5, both the devices have codename vince.
Edit:
If you wanted to ask what the codename for the Redmi 5 is and not about Remi 5 Plus, the codename for Redmi 5 is "rosy". This is the phone with 5.7" screen and Snapdragon 450
