Another big sell from Samsung, is Group Play - and again we can't really see the point for certain elements. Yes, we know this is getting to be a theme with the phone, but bear with us here.
One of the most popular functions Samsung was keen to talk about was the music sharing - the idea being that if you've got more than one Galaxy S4 kicking around (presumably not by yourself) you can set up a Group Play group by making a Wi-Fi hotspot and stream the music to all phones at once.
The clever idea is that multiple phones can connect, and each can have their own speaker setting in a surround sound setup. The downside is that you'll never have that many Galaxy S4s in one place, and even if you did, a single small speaker at the back is hardly going to be enough to wipe out your home speaker system.
We can see this being useful going forward though, as if you have other devices with Group Play functionality - such as wireless speakers - you can easily create a virtual surround speaker system using just the Galaxy S4.
One other thing that REALLY annoyed us was the fact that Group Play on the likes of the Galaxy S3 or Note 8.0 is a completely different app, despite having the same name and icon. You can't do anything we mentioned above with these devices - you can barely connect the two together.
It seems an oversight from Samsung to remove this function, as many people will already have bought heavily into the Samsung ecosystem.
Building neatly on from the WatchON app, we've got the all new Samsung Hub ready and waiting to be played with. This is a much better idea than before, where all the disparate entertainment sections were scattered around the phone.
With this attractive hub, Samsung is looking to take a real crack at iTunes by making a holistic experience, whether it's games, music or video you're after. The UI, as we mentioned, is really nice, with swipes allowing you to get through all the content, and a home screen that throws up all the different kind of content it thinks you might like.
It's not got a universal appeal, as even though you're paying a high dollarpound price for the latest blockbuster, you can't watch move that content onto your larger screen without a HomeSync device. Connecting to a TV or streaming using AllShare won't let you play video you've purchased from the Samsung Hub, which feels like a massive trick missed here, although Samsung tells us it's due to a licensing issue.
HTC Watch can do it, and the prices are often cheaper. What gives, Samsung?
It's not really a great place to get all your content thanks to the really high price, and it would be excellent to see a wider remit by including third party apps to supplement the lack of functionality in places.
For instance, and we're sure there's a licensing reason for this, how great would it be to see Netflix in the Video Hub to allow instant streaming, rather than having to pay £10 or so just to get a video in SD that you can only really watch on the phone?
