Samsung Galaxy S6 review

Samsung has launched two phones, Samsung Galaxy S6 And S6 Edge at MWC2015.S6 stunning metal bezel that cascades into sophisticated glass (it has a metal chassis, and glass covering the front and back) with dual-edge screens. Both the S6 and S6 Edge comes in charcoal, White and Gold.The S6 Edge is slim, sleek, elegant, the S6 gets a surfy blue and has a curved edge. 

The S6 is lighter than its predecessor S5 and feels more balanced and solid than the S6 Edge.S6 has the power button located at the right side of the phone and the volume controls to the left side. The top has the menu button and microphone. The bottom edge has the charging point, power boosted speaker.

The downside to this phone is that there is no removable back panel meaning you cant change the battery or memory card. You cant upgrade from say 32G to 64G. Also the battery capacity hasnt changed that much (its even now lower), you have 2600mAh for the S6 Edge and 2500mAh for S6 and 2800mAh for its predecessor Samsung S5. It can give your 2 hours of HD video playback with just 10 minutes of charging.

One amazing feature is the wirless charging and also a normal chager too. The front facing camera is 5MP while the back camera is 16MP with 0.7 seconds activation for faster response and auto real-time HDR. 

It has a beautiful 5.1" Quad HD Super AMOLED display with a 2560 x 1440 pixel QHD resolution. And for a hint on the price,

Samsung Galaxy S6 32 GB: €749 (around £560, $855, AU$1100)
Samsung Galaxy S6 64 GB: €849 (around £635, $970, AU$1240)
Samsung Galaxy S6 128 GB: €949 (around £710, $1085, AU$1390)
