Look and Feel
I noted in my Galaxy Note II review that I did not like the plastic feel of the phone, and my thoughts continue here. The Galaxy S4 feels cheap, because of its plastic exterior. Samsung has already said that they're working on this, and that its next flagship smartphone will be arrive with a premium feel. Hopefully they've learnt their lesson from Sony and better yet, HTC.
The Galaxy S4 doesn't feel much bigger than the S III, where it measures in at 5.38 x 2.75 x 0.31 inches. Thanks to its light weight of just 130g, it feels lighter than any other smartphone I've used. I would say this is thanks to the smartphone being pancaked across a larger space, instead of condensing it into a smaller, say, 4.5-inch device.
It's incredibly light, which is one of the first things you'll notice about it. Going hand to hand with a Galaxy S III to the S4 was very surprising to say the least. Looks can be deceiving, but the S4 definitely feels lighter, even if it's just that 1g lighter in reality.
The front of the Galaxy S4 includes that gorgeous, and obvious 4.99-inch 1080p display. Around that we have some notification lights in the top left, followed by sensors for your eyes (we'll talk about that later), the earpiece for phone calls, front-facing 2-megapixel camera and down the bottom, we have a physical home button. To the left of that, we have a touch button for "menu" and to the right another touch button for "back".
Flipping the S4 onto its back, we find that gigantic 13-megapixel camera, below it we have the huge LED flash. Below the LED flash we have the obvious Samsung logo, and near the bottom we have a 4G logo. To the left and slightly below the 4G logo is the great rear speaker.
On the right side of the phone we have the power button and access to open up the Galaxy S4.
On the left of the Galaxy S4 we have the volume rocker.
On the very top of the phone we have the usual 3.5mm headphone/speaker jack.
On the bottom of the Galaxy S4, we have the microUSB for charging/syncing, as well as the microphone.
The Galaxy S4 can be opened up for expandable storage through a microSD card, which supports a 64GB microSD card. The micro-SIM slot is also accessed by removing the back, and the battery is also removable, and hence, replaceable.
