Introduction to Samsung J750
The Samsung J750 is a feature phone that was announced in October 2007 and subsequently released in January 2008. Although it has since been discontinued, its design and features offer an interesting insight into the evolution of mobile technology, as it sits at the transitional period between older generation low-tech phones and modern smartphones.
Design and Build
The Samsung J750 boasts a compact design with dimensions measuring 99 x 48 x 18.4 mm and weighs a mere 79 g, making it lightweight and easy to carry. Its black finish presents a classic design choice that was popular during its era. The phone uses a Mini-SIM card and features a removable Li-Ion 800 mAh battery. Although not a touchscreen device, it is fitted with a TFT display capable of showing 256K colors, a vibrant offering for its time.
Display
Equipped with a 1.8-inch display, the Samsung J750 offers a resolution of 176 x 220 pixels, with an approximate pixel density of 157 ppi. Though the screen might seem small by today's standards, during its release, this size offered a great balance between portability and usability. The screen-to-body ratio of around 21.5% reflects the design priorities of the era.
Camera Technology
The Samsung J750 features a single 1.3 MP rear camera, capable of basic photography needs. Video recording is also possible with this camera, which was a relatively advanced feature for feature phones at the time. Additionally, there is a VGA videocall front-facing camera for video calls, an impressive feature that adds to its connectivity options.
Network Capabilities
The device supports GSM/UMTS technology, with 2G bands covering GSM 900/1800/1900 and a 3G band for UMTS 2100. This ensures basic internet connectivity and decent call quality, with speeds up to 384 kbps, which were typical speeds before the LTE era. Despite the basic internet service, it provided a useful means for communication even in network settings that were considered advanced at its time.
Memory and Storage
The internal storage of the Samsung J750 is limited to 8MB, which might seem minuscule today, but it allowed for essential phone functions and storage of text messages, contacts, and small Java applications. It supports microSD cards (in a dedicated slot) for expandable storage, allowing users to store additional media files. The phonebook has a capacity of 1000 entries and supports photocall functionality.
Battery Life
The 800 mAh removable battery provides up to 300 hours of standby time and offers a talk time of up to 3 hours, making it a reliable choice for everyday use. The longevity of the battery, combined with its ease of replacement, ensured that users could maintain communication without needing frequent recharges.
Connectivity and Entertainment
In terms of connectivity, the Samsung J750 includes USB 2.0 for direct connection to a computer and Bluetooth 2.0 with A2DP for wireless connections to peripherals such as headsets and other phones. Although it lacks features like WLAN, positioning, or radio, these were typical limitations of the time period and do not hinder its primary communication use.
As for entertainment, the phone offers Java support (MIDP 2.0), allowing users to run Java-based applications and games. It supports downloadable polyphonic and MP3 ringtones and has a loudspeaker feature for music playback.
Messaging and Browser
The messaging capabilities include SMS with a storage of up to 200 messages, MMS, and Email. The phone also supports a basic internet browser, WAP 2.0/xHTML, and HTML NetFront 3.4 for simplified web access.
Market Position and Conclusion
When released, the Samsung J750 targeted consumers who desired a balance of multimedia capabilities and practical phone features. Priced at approximately 70 EUR, it was an accessible option for those seeking more features than a basic phone but without the high cost of early smartphones.
Overall, the Samsung J750 is a reflection of an era when feature phones were evolving to meet the rising demand for more features, melding communications with a multimedia experience. Despite its discontinued status, the phone remains a notable example of pre-smartphone cellular technology.
