Samsung hasn’t just made the screen larger. The stunning 1,920 x 1,080p Super AMOLED Samsung Galaxy S4 screen is a serious boost from the S3’s 720p screen that creates an instant wow factor. It’s arguably the best screen ever seen on a smartphone and proves the Samsung Galaxy S4 is more than a spec baiting feature fest – it’s a quality product.
At 7.9mm thick, 136.6mm tall and 69.8mm wide, the Samsung Galaxy S4 is actually 0.8mm narrower and 0.7mm slimmer than the S3. It tips the scales at just 130g – 3g less than the S3 and a genuine featherweight. Unlike past models, however, it doesn’t feel unnervingly light, instead, balancing its weight evenly and reassuringly across the handset’s full length.
In terms of connectivity the Samsung Galaxy S4 features 2.5G, 3G and 4G LTE, it also comes with 802.11 a/b/g/n/ac WiFi, plus GPS / GLONASS, NFC, Bluetooth 4.0, MHL 2.0 and IR LED, plus Accelerometer, RGB light, Geomagnetic, Proximity, Gyro, Barometer, Temperature & Humidity, Gesture sensors..
