The Nokia 6670 is yet another solid entry in the Finnish mobile phone maker's Series 60 portfolio. The sturdy handset -- designed primarily for corporate use -- sports a so-called 'leaf shape' similar to the 7610. The 109 by 53 by 21 millimetre smart phone -- about 2 millimetres thicker than the 7610 -- is nice and broad, with a relatively sizeable screen a big useability positive. Some awkwardness on occasion in carrying a handset that size around in a regular jeans or pants pocket, however.
The 176 x 208-pixel active TFT dominates the top half of the phone, with a 65K colour display that doesn't quite match up to that of O2's Xphone II. The camera lens occupies a small area on the back of the phone.
While the unpopular parabolic keypad design that featured in the 7610 has been appropriately banished, the new design here shows that the perennially difficult area is no closer to resolution. While the main keypad is relatively easy to use, the narrow keys flanking the numerics are too small and consequently irritating to use. Similar to a number of mobiles being released now, the plastic keys and phone casing feel a trifle cheap and a user could be forgiven for querying the handset's robustness.
Features
On a more positive note, running on the Symbian operating system typical of Nokia Series 60 phones, the 6670 comes loaded with applications. Notably, the Quickoffice suite allows users to read Word, Excel and PowerPoint files and email attachments on-the-go, a significant upgrade from the 7610. The usual PIM functions like calendar, to-do, notes, calculator and wallet are also included. On the whole, the user interface is fast and responsive. Messaging on the 6670 is also smooth, with predictive input, MMS and email support available.
The main multimedia feature of the 6670 is the 1-megapixel camera capable of up to 1,152 x 864-pixel snapshots. Pictures taken with the camera are clear and crisp, though colour reproduction is a little less vibrant than desired. Like the 7610, the 6670 suffers from a lack of configurable imaging options. Other multimedia features include Realplayer for MP3 music and video clips as well as picture and movie editors.
The 6670 offers only mono audio output with its single earpiece which fades in comparison with many Samsung and Motorola stereo offerings. On the plus side, the internal handsfree function works well and the speakerphone is clearly audible.
The triband 6670 supports GPRS, WAP, Java and Bluetooth connections. While it lacks an infrared port, Nokia compensates for this by bundling a USB cable with the phone for data and file transfer with the desktop PC.
Disappointingly, only 8MB of internal storage is available, though the included 64MB reduced-size MMC card alleviates the issue to some extent.
We found no cause for concern regarding reception and voice quality of the 6670 throughout the review period. The 900mAh Lithium-ion battery lasted for about three-and-a-half days on normal usage, exceeding that of the 7610.
