Samsung Ativ SE boots Windows Phone 8 GDR3 out of the box. You can take a look at a short video of the smartphone in action below.
A push on the unlock button reveals the lockscreen, which displays the current time and date and shows calendar events, emails and missed calls. Pushing the volume rocker in either direction will bring the sound switch and music controls on top of the screen.
There's a reasonable level of flexibility and functionality to the lockscreen - the Live Apps service allows apps to display notifications, weather, and images. You can set one app to display big notifications ("detailed status") and up to five more apps to show a less detailed quick status. There are already apps in the Store that display the battery percentage on the lockscreen via those kind of notifications.
The lockscreen wallpaper can also be controlled by apps - you can let the music player replace the lockscreen image with the album art of the currently playing track, or let one of the installed apps choose the image (e.g. Bing's beautiful background images or photos from your Facebook account).
The Modern UI is a vertical grid of Live Tiles, which can be reordered any way you like. Almost anything can be pinned to the homescreen - apps, contacts, web pages and more. Unfortunately, the app launcher is still just an alphabetical list of all apps, no folders or icon grid. We don't think it works too well on a large display.
Windows Phone 8 lets you resize the live tiles. Upon a tap and hold, you'll get an extra resize button, next to the unpin one. You can opt between quarter, normal and double size. If you select the smallest one though, the tile will be just a static icon (as is in the regular menu).
Most Live tiles display relevant info such as the current date, pending calendar events, missed calls, unread emails and more (third party apps do it too). The Marketplace tile displays the number of updates available, while the Pictures tile is essentially a slideshow of your photos. It's nice to have all that info always available at-a-glance. You can look at them as homescreen widgets of sorts.
WP8 can do multitasking, though not with the level of user control that Android allows. Apps not in the foreground are suspended, but the OS has ways to take over and carry out the task for them (e.g. continue playing music). If an app needs to run in the background (sat-nav clients, messengers, etc.) it can though we've had variable success rate with messengers that run in the background such as Viber.
Anyway, Microsoft is delivering a much better multi-tasking with the Windows Phone 8.1 update and the Ativ SE should get the update just like the other Windows Phones.
The new feature in GDR3 is that you can "close" apps by hitting the X button. It's not as comfortable as swiping apps away, but at least now you have control over the recent apps list. Windows 8.1 enables the swiping gesture as well.
Opening the settings menu on the Samsung Ativ SE displays two sets of options: you can swipe between the System tab and the Applications tab. System covers all the settings you can think of like sounds, color theme, Wi-Fi, Bluetooth, Accounts, etc. The Application settings let you configure each app you have on the device.
We would've liked to see some kind of quick toggles in Windows Phone 8 to spare you the need to go all the way to the settings menu to enable Wi-Fi, Bluetooth, GPS and the likes. Fortunately, Windows 8.1 offers such UI.
There is one new setting as part of the GDR3 refresh - screen rotation, where you turn on/off the automatic UI rotation. It requires you to exit the app, find it in the settings, enable it and then get back to the app. The same goes for all the other settings, it's just too many steps for such a common task.
Another missing feature is a place where you can see all of your notifications from various apps. Live Tiles manage to show notifications from each app to some extent, but they don't really have enough room for things like e-mail subject and such, while Android and iOS notification areas do. Microsoft will deliver that with Windows 8.1 as well.
Windows Phone comes with the Data Sense app, which shows you the amount of data you've used. Both cellular and Wi-Fi traffic is accounted for. There are different data limit types: one-time, monthly and unlimited. The first two accept custom bandwidth limit values, while the latter is applicable if you have an unlimited data plan, but would still like to track your usage. With GDR3 there's an option to prevent data usage when roaming.
Data Sense can also restrict the background data usage for all apps if you are near a preset data limit. This will prevent some apps from functioning properly, though.
Driving Mode can be enabled automatically when the phablet connects to a specific Bluetooth device (i.e. your car's stereo). This mode mutes all notifications except calls and texts, but you can mute those too. If you do, you can set an automatic reply text.
Microsoft is trying to appeal to business users too - a company can create its own Hub where employees can find news, calendars and other info relevant to their work. Companies can also create their own apps that only employees can install.
Samsung Ativ SE also supports voice commands - you can dictate or have the phone read text out, you can initiate searches and so on. Unfortunately, the Windows assistant is still far behind the competition as far as recognition speed and accuracy are concerned.
Most importantly, for those who are interested, Microsoft offers an easy path to get a hold of a Windows Phone 8.1 Developer Preview. All you need to do is register as an app developer for free.
