The BLU C4 is a budget-friendly smartphone that was launched in August 2018. It offers basic functionalities suitable for users who need a phone for everyday tasks like calling, messaging, and light browsing. Despite its low price, it holds its own with essential features that cater to a segment that values affordability and simplicity over high-end specifications.
The BLU C4 has dimensions of 124.3 x 64.2 x 10.9 mm, making it compact and easy to handle. It weighs just 118 grams, which contributes to its portability. The phone supports dual SIM functionality, accommodating two micro-SIM cards, which is a useful feature for users who manage multiple lines. Its design is straightforward and practical, with a focus on meeting basic aesthetic standards rather than luxury.
The device features a 4.0-inch IPS LCD screen with a resolution of 480 x 800 pixels. This results in a pixel density of approximately 233 ppi, which is reasonable for its size and price category. The display provides adequate clarity for standard usage, such as reading texts, browsing the internet, and viewing images. With a screen-to-body ratio of around 57.1%, it offers a decent viewing area while maintaining a compact form factor.
Under the hood, the BLU C4 runs on a quad-core 1.3 GHz processor paired with a Mali-400 GPU. It is equipped with 512 MB of RAM, which supports basic multitasking and app usage. This modest configuration is manageable for running applications in the Android 8.1 Oreo (Go edition) environment, tailored for budget smartphones to optimize performance with limited resources.
The internal storage of the BLU C4 stands at 8GB, which suffices for core applications and some user data. However, its storage capacity is expandable via a microSDXC card, allowing users to store more media and apps without the constraints of fixed storage limitations.
The phone is equipped with a single 5 MP rear camera that includes an LED flash, supporting video capture at 720p@30fps. Similarly, the front-facing camera also has a 5 MP sensor, suitable for basic selfies and video calls. The camera features are basic, in line with what is expected in this price range, focusing on achieving satisfactory photo quality in well-lit conditions.
The BLU C4 houses a Li-Po 1300 mAh battery, which may seem minimal by modern standards but aligns well with the phone's low power demands. It provides a standby time of up to 400 hours on a 2G network, or up to 450 hours on a 3G network. For active usage, it affords up to 18 hours of talk time on 2G and up to 13 hours on 3G, ensuring a full day of basic use without needing frequent recharges.
The connectivity options on the BLU C4 include support for GSM and HSPA technologies, allowing for 2G and 3G network connections. It features Wi-Fi 802.11 b/g/n for basic internet connectivity and Bluetooth 2.1 for short-range data transfer. There is also GPS functionality for basic navigation requirements. Audio support includes a 3.5mm headphone jack and FM radio, enhancing its multimedia capabilities.
The BLU C4 includes an accelerometer sensor, contributing to functionalities like screen rotation and basic motion detection for compatible apps. It supports microUSB 2.0 for charging and data transfer. The phone is available in three colors: Black, Gold, and Blue, catering to varying user preferences. With a price point around 40 EUR, it stands out as an affordable choice for individuals seeking a basic, reliable handset.
The BLU C4 is a practical choice for those in the market for an introductory smartphone experience without the expense of flagship devices. It is particularly appealing to users who prioritize budget over high-spec performance, providing all the essentials needed for communication, simple photography, and internet access. While it does not offer the power or advanced features of higher-tier smartphones, its utility in handling everyday tasks efficiently makes it a worthwhile consideration.
