One of the first mid-range windows devices from Nokia was the Lumia 620.
The phone came out in January 2013 and was very successful due to its competitive nature. However, 12 months is a long time in the mobile phone industry and it is especially true in the case of screen sizes. In order to compete with the new trends, Nokia came out with the Lumia 630 a few months back.
One of the strong points of the Lumia 620 was the very compact nature. This was possible because of a 3.8 inch display that was only slightly larger than the original iPhones. This also turned out to be the disappointing aspect of the phone heading into 2014. Nokia corrected this aspect by providing the Lumia 630 with a large 4.5 inch display. The substantial increase in the screen size has not been met with an equal increase in the resolution. As a result, the Lumia 630 offers a lower pixel density than its predecessor. A key difference between the displays of the two phones, apart from the screen size, rests in the technology. The Lumia 620 came with a normal TFT display whereas the Lumia 630 uses the IPS panels like many high end phones.
Internally, the two phones offer only 8 GB of memory. This especially feels low on the Lumia 630 with its large 4.5 inch display. Since external memory card support is provided on both phones, one can add memory at a later stage depending upon the usage patterns. The Lumia 630 clearly feels a step ahead in this regard as well, because of its support to 128 GB of memory, compared to the 64 GB of memory support on the Lumia 620. The RAM, which is needed for a better multitasking experience, remains similar at 512 MB.
Performance is likely to be given a huge boost from the Quad core processor on the Lumia 630. This is a substantial bump up from the dual core 1 GHz processor on the Lumia 620. The Quad core processor is clocked at 1.2 GHz and it makes it one of the fastest Windows phones in this segment. However, the OS is extremely well optimized that one should not be surprised to see the Lumia 620 support the latest 8.1 version without many hiccups.
Nokia offers only a few additions to the cameras present in its entry-level models on these phones. These additions include features like the LED flash, which are otherwise absent on the lower end devices. It is, however, surprising to see the flash being omitted on the Lumia 630, even at this price point. Further, full HD video recording is also not possible on these devices, as they are limited to only 720p videos. The Lumia 630 also lacks the secondary front facing camera, which is present on the Lumia 620 – albeit only a VGA camera. The Lumia 620 costs $180 while the Lumia 630 costs $200.
