- Poor pixel density and screen resolution
- Absence of ClearBlack technology
- Middling processor performance
First up is the display. At 4.7 inches, it has one of the largest screens available in the Nokia lineup. Due to the larger screen real-estate reviewers found it easier to navigate around the Windows menus and using the onscreen keyboard. Since the screen is so large the 800 x 480 resolution results in a very low pixel density of 201ppi. Most experts noticed lack of detail when browsing the web or viewing HD quality images.
Aside from the poor resolution, the device also does not utilize ClearBlack technology. Reviewers immediately noticed its absence as black edges on the screen and above the soft keys looked dark blue. Unfortunately, the colors washed out even further as experts attempted to view the display from various angles.
The second notable feature of the phone is its 4G LTE connection. When connected, experts report download speeds of 100Mbps and upload speeds of 50Mbps. If LTE is not available, it also connects to HSDPA, which offers a decent 42Mbps download speed. As with all smartphones, this one also offers single-band Wi-Fi.
With a 1.2GHz dual-core processor and 512GB of RAM, the Lumia 625 doesn't top any benchmark tests, but most critics found it fast enough to run Windows 8 and basic apps smoothly. Once reviewers started testing out more intensive apps, the device lagged significantly.
In addition to the processor and RAM, the device sports 8GB of internal memory, 7GB of cloud storage and a microSD slot. Unfortunately critics discovered that the phone does not have WP file manager, so any unrecognizable files like ZIP or RARs can only be accessed via a computer.
On the back you'll find a 5 megapixel camera. Although it certainly doesn't stack up to the 41MP of the Lumia 1020, GSM Arena says that it fares "surprisingly well as far as image quality is concerned." In both low and bright light conditions, the camera exceeded most critics' expectations by producing excellent contrast, color and dynamic range. Expert Reviews did notice a loss of detail when zooming in, however.
As a whole, reviewers were left unimpressed by the device. The Next Web says the phone "leaves me with little impression of anything whatsoever. It's about as middle-of-the-road as you can get…" V3 adds to the sentiment by saying, "…the device is fairly dull…we can't really see the 625 enticing too many new users to the Windows Phone ecosystem."
