Hey there! I am not very well versed in that specific camera so I am not sure how it operates. If it is just a camera, does it need to connect to the hotspot? You phone will only connect to a wireless hotspot if you have Wi-Fi on and tell the phone to connect to it. Have you tried talking to Samsung directly about this? They may have more insight as to the inter-workings with the device and iOS.
Just checking in here. Did you get a chance to speak with Samsung yet?
Happy Sunday! We just wanted to touch base here and see if you had any updates from Samsung about this. Please let us know if they were able to help you get it working, we'd be stoked to have the steps laid out here in case any future Community member has the same question! Thanks.
Samsung has published application update 1.3.17062701in AppStore.
In this version it was working fine.
I guess they have provided fix for iPv6 only operator locked devices like TMobile.
But do not forget to remove the DNS if you have put it manually or forget the network and connect again with password.
