It's been a regular one on our list of Cons that Symbian is lagging behind Android and iOS in user experience, but Belle is a leap forward. The key elements are the new homescreen and menu, the updated native apps and overall polish of the interface.
For a quick walkthrough of the interface, you can watch this Nokia 701 video demo that we’ve published previously. The software on both phones is identical.
The widget system introduced by Symbian^3 was incomplete to say the least. Now with Belle, you get up to six homescreen panes (up from three in Anna) and you can delete unneeded ones. Each homescreen has its own individual wallpaper, rather than one for all to share.
Widgets themselves have dropped the one-size-fits-all philosophy and now come in up to five sizes. Widgets are resizable too. In addition to widgets, you can also put shortcuts on the homescreen - the end of the silly shortcut widgets.
A tap and hold on a widget or shortcut activates edit mode, but only for that widget/shortcut. You can move it, delete it or (where available) access its settings. While editing one widget, you can touch others - there's no mass edit mode (which looks like a blunder to us).
The bottom of the homescreen has three virtual buttons - Menu, Dialer and Homescreen settings. With these buttons, Nokia can go button-free at the front if they want to, just like they did with MeeGo.
The other big addition to the homescreen is the pull down menu at the top of the screen - think Android's notification area or the similar menu available in iOS 5. This is where notifications wait in line for your attention, but you also get toggles for mobile data, Wi-Fi, Bluetooth and Silent mode.
This pull down menu is available on any screen so you can also quickly change a setting and look up new events.
Moving on, the main menu has changed as well - it's now completely flat, no level upon level of subfolders nonsense any more. You could create folders if you like, you can also sort icons alphabetically or manually.
You can choose the Arrange option and move menu items around, but you can't drop a shortcut in a folder. To do that, you have to press and hold on a shortcut, choose Move to folder and then select the desired folder. There are also Add to homescreen and delete options here.
This arrangement isn't as convenient as in other OSes and it's at odds with how the homescreen works. On the homescreen you press and hold to move an item, while a tap and hold on a menu item pulls out a menu. To move items around you have to hit the Options key and choose Arrange.
The task manager in Symbian Belle is virtually unchanged - press and hold the Menu key and it pops up. It fits three thumbnails of the currently open apps. It's worth noting that hitting the End key will terminate an app, while pressing the Menu key just goes to the homescreen with the app active in the background.
Symbian Belle feels very smooth, which is probably due to a combination of the new software and the faster hardware. The upgraded CPU (1GHz) makes sure that even heavy multitaskers won't have issues - Symbian requires fewer resources than Android, for example.
