The Galaxy smartphones are medium-high that are positioned one step below the Galaxy S range, but represent a good compromise between design and performance. Samsung has chosen premium materials (aluminum and glass) and reduced thickness of the frame to provide greater viewing area. The Galaxy A3 (2016) has a display Super AMOLED 4.7-inch HD resolution (1280 × 720 pixels), while the Galaxy A5 (2016) has a screen of 5.2-inch full HD (1920 × 1080 pixels).
The hardware of the Galaxy A3 also includes a 1.5 GHz, 1.5 GB RAM, 16 GB of flash memory, microSD slot quad core processor, cameras from 13:05 megapixel camera with f / 1.9 and optical stabilizer. The Galaxy A5 instead incorporates an octa-core 1.6 GHz processor and 2 GB of RAM. Storage and cameras are identical, as well as connectivity (WiFi 802.11b / g / n, Bluetooth 4.1, GPS and NFC) and sensors (compass, accelerometer, proximity, ambient light, and Hall effect). The Galaxy A5 also has a fingerprint reader .
Unfortunately, Samsung has installed Android 5.1 Lollipop, so we have to wait to take advantage of the new features in Android 6.0 Marshmallow. The prices of the Galaxy A3 (2016) and Galaxy A5 (2016) are, respectively, 329 euro and 429 euro.
Once again a smartphone Samsung is positioned at the top of a ranking. DisplayMate published the results related to the quality of the display Super AMOLED of the Galaxy S7. The new smartphone is the best one among those tested by the company, exceeding even the excellent performance achieved by the Galaxy Note 5.
The Galaxy S7 screen has a diagonal of 5.1 inches and a Quad HD resolution (2560 × 1440 pixels, 577 ppi), features identical to those of his predecessor. The Galaxy S7 edge, however, has a 5.5-inch display and 535 ppi. Color fidelity, color gamut, viewing angles and consumption remain at the same level of the Galaxy Note 5, but the Super AMOLED panel of the new Galaxy offers better performance in brighter environments and outdoors in the sunlight. The brightness reaches a fact value of 855 cd / m 2, while the low reflectance allows an easy reading outdoors.
The Galaxy S7 also offers Personalized Automatic Brightness Control that allows you to set the brightness level of the screen based on the amount of ambient light, while maximizing battery life. The smartphone so remember user preferences and applies them automatically. According DisplayMate, the Galaxy S7 is the first device that adjusts the brightness properly.
The company has also expressed a positive opinion on the functionality Always-On Display allows you to view the date, time, battery level and notifications when the smartphone is in standby mode with the screen off. The text and graphics are displayed on a black background, without impacting negatively on the autonomy (only 1% of consumption in an hour).
