Hello and thank you for choosing JUSTANSWER.com
BLU is a smartphone company located in Miami, Florida, who makes very low-cost smartphones. Earlier this year, BLU came out with their Energy line of smartphones. Basically, low-spec devices with huge batteries.
The built-in BLU Help app is essentially a shortcut to a webpage, which allows you to register the device, checkout the manual and also get service on the phone. So if you are having issues with your BLU Energy X, this is a great way to get help from BLU.
