I want to know what's that and how to remove it 

[SK1955]

[geetacharan]

[Anikroyale]

Reinstall WhatsApp

[geetacharan]

lol,I thought it would work but no use

[geetacharan]

it's still showing

[Anikroyale]

It should go away after reinstallation. If it didn't then I don't know how to do it. If you get to know how to do it, please inform me.

[geetacharan]
