Vodafone Smart Prime - Vodafone Start

Hi there

I have a Vodafone Smart Prime phone. Yesterday and today I get alerted to an error: 'Error updating Vodafone Start'. Nothing more is provided.

1. I have no clue what Vodafone Start does.

2. How do I update this? Or is it safe to remove Vodafone Start from my phone (not listed in the App list though)?

Many thanks

Stevie
