Hi @StefanVoit.
Are you still having the same issue? Did you manage to get it sorted? Here's a few things you can try with the SmartThings app:
• Clearing cache data for the app
• Reset appliance
• Logging out of the Samsung Account on the mobile device via App Manager
• Turn mobile OFF/ON
• Ensure mobile device/appliance is on the latest software/firmware
Thank you for providing the model code, it should also have an extra couple of characters: /EN or /EG or similar. This will help identify which country it is designated in.
Can you advise on where you purchased it from (and what country) most of the support here is UK based, however we are happy to help everyone!
The bad news and I am sorry to say this, is that this specific model is not WiFi equipped, the user manual is a multi-country and multi model, it does state that it applies only to models with WiFi function (I downloaded the benelux region and my limited dutch says it says the same as below from the English manual)
This is why I ask where you purchased it from.
I have checked the Samsung webpages in the benelux region (French & Nederlands) and it doesn't reference the WiFi for this model. For WiFi funciton you woiuld need to purchase this model: VR10M703NWG
I think you may need to go back and have a chat to the retailer
Even without the WiFi function it is a great robot vacuum - mine is called David, have you named yours yet?

Hello and thx for the reply.
I live in Belgium and the last 2 letters are EN in the code...i didn`t think it was very important, that`s why i left them out.
Yes, it`s a good piece of equipement, but the non-connected ones have limited functions for programming , not to mention the fun of playing with it from my phone 
. I will go back to the retailer (he was extra sure it`s network ready) , not only for this, but after a week of using it, my battery life is only 20-ish minutes on low sucktion power, a long way from the advertized hour..
Yes, naming it was the first thing my kids did, we named it Basil :))
