Samsung Galaxy A03s: Design

The Samsung Galaxy A03s is a low-cost phone model, and the strengths of the models in this segment are often not in the design. The outer shells of these models are usually not made from high-grade materials such as glass, metal, or are treated with water resistance. Even so, Samsung Galaxy A03s is still a phone with good build quality and high level of finishing.

The device has a seamless back design from the back to the frame. The back of the device is also designed quite carefully. At first glance, you can feel the typical design language of the Galaxy A series, with clean lines, rectangular camera clusters and a grip surface.

The Samsung Galaxy A03s version that we used in the review has a blue back. During daily use, the back of the device has a bit of fingerprints, but it doesn’t show much on this color version.

The front of the machine is equipped with a 6.5-inch LCD screen. The screen is cut with a small teardrop-shaped array to make space for the 5MP selfie camera and a few other sensors. This cutting array is not too large in size, and will not affect your actual use experience much.

The screen is protected by a layer of flat glass, but we don’t have any information on the manufacturer of this glass. What we do know is that the screen of the Galaxy A03s does not come with a protective film. This is a significant difference when compared to other competitors in the low-cost segment.

The top edge of the Galaxy A03s is equipped with a single secondary microphone. Meanwhile, the bottom edge of the device is equipped with all kinds of different details, including a 3.5mm headphone jack, main microphone, USB Type-C port and 1 speaker strip.

And finally, the power button and volume up and down buttons are located on the right edge. In addition to the on/off function, the power button of the Galaxy A03s is also integrated with a fingerprint sensor, helping you quickly log in the system’s password every time you take out the device to use.

Galaxy A03s is not a phone with a compact design. In fact, due to the rather thick bezel, the overall size of the device is on par with most 6.7-inch mid-range models on the market. Equipped with a 5000 mAh battery, the device has an overall weight of 196g.
