The product does not include 3G technology so users can only access the Internet via Wi-Fi. This is considered the biggest disadvantage of this product when 3G network is growing strongly in Vietnam today and is being integrated by many mobile phone manufacturers for their products. Thanks to 3G, your mobile phone can access high-speed Internet anytime, anywhere without having to rely heavily on Wi-Fi coverage. Thus, even if it focuses on integrating and improving much to be able to receive emails automatically or quickly update on social networks, the C3 will also have to "suffer" without Wi-Fi.
Camera limited
The phone has only one main camera on the back with 2MP resolution, without autofocus or flash, even if the digital zoom is up to 4x. Therefore, if compared to other phones on the market today, this camera is only considered to be 'decorated'. Furthermore, with a resolution of 1600 x 1200 pixels, the video recording quality from this phone is also quite poor. Image quality may not be too bad when viewed on a phone but it is really boring when you transfer them to your computer to watch.
Besides, when shooting is completed, the user cannot immediately delete the photo but must wait for more than 30 seconds to delete it. On the other hand, because there is no GPS locator function, this means there is no option to tag photos so that they can be easily managed by geography.
Slow application transfer, do not run multitasking
The transfer speed between applications is also not very smooth, sometimes we have to wait a few seconds, especially when you open multimedia applications. Moreover, the product is not designed to run multiple applications at once (multitasking). This is considered a restriction for current phones when this feature is currently very interested by users.
Poor screen
With a 2.4-inch screen size, 320x240 pixel resolution, the Nokia C3 phone is not a perfect choice for browsing the web or running multimedia entertainment applications.
What's more, the advantage of the QWERTY keyboard is that it is convenient for users to type. However, easy typing but not able to edit documents right on the phone also makes the product become limited and not favored by office workers.
Despite the lack of modern functions of smartphones today, the Nokia C3 has the advantages of QWERTY keyboard, social network, rich chat and email features as well as long battery life and especially with quite affordable price.
