About This Brand
Samsung is well known for its innovative designs and has one of the largest lineups of smart phones that run on the Windows and Android operating systems. Samsung smart phones have the industry's most advanced technologies the Android platform has to offer. They include Multi window, which lets you interact with two apps simultaneously on one screen. For instance, you can watch a video while viewing an e-mail, or you can use Google Maps and messaging. The front-facing cameras on many Samsung models monitor you eyes while you're reading a Web page or other documents to prevent the screen from timing out. Some Samsung phones can also wirelessly share large files between each other after the phones are bumped together. Another innovation is touch-free gestures/controls (air gestures) that let you accept a phone call, move to another message, flip through photos, or skip to the next song in your playlist by waving your hand in front of the phone. Noteable lines include the Samsung Galaxy S and Galaxy Note series.

Camera (megapixels) Specifies, in megapixels, the maximum resolution of the rear-facing built-in camera. A camera with a 0.3 megapixel value is also referred to as VGA.
Camera recording resolution The maximum recording resolution of the phone's primary video camera: Ultra HD, 1080p, 720p, or SD (Standard Definition).

Memory card Many phones have slots that accept memory cards, typically microSD, to expand storage capacity by as much as 128GB. The removable cards can also serve as an easy way to shuttle files between your phone and other devices--provided that the phone's maker didn't bury the card slot behind the battery cover.
Touch screen Full touch-sensitive displays respond to light contact with a stylus, finger, or both. They provide an alternate, and sometimes more direct, method to input data and launch phone features and controls. But they often require two hands to operate, and they smudge more frequently than their non-touch counterparts.
QWERTY keyboard Keyboards make composing and editing text and e-mail messages much easier than a keypad does. Some phones have keyboards that try to save space by having some letters, numbers, and symbols share a key. Those "condensed" keyboards, though still more convenient than a keypad, are not quite as easy to handle as full QWERTY keyboards.
Document editing All smart phones, and some conventional cell phones, allow you to review documents. Some models add the convenience of creating, deleting, and editing them out of the box.
Music player Indicates the phone has a built-in MP3 player. Most players have full capabilities, allowing you to sort or view tracks according to genre, album or artist, playlists, etc. They also typically have more than one playback option, such as repeat and shuffle. The small number of phones that lack these convenient features are rather cumbersome to use.
Voice command This feature allows you dial numbers from your phone book by speaking the name, without the usual training. You can also dial numbers by pronouncing the digits.
GPS navigation All phones have some type of location-based technology to help emergency responders find you when you dial 911. Many phones support GPS Navigation, services which integrate GPS with maps and search engines to give you real-time, spoken, turn-by-turn directions to an entered address, or to help you find nearby businesses by name or category, such as Joe's Pizzeria or hospitals. We indicate which phones have GPS navigation capability as reported by the carrier and manufacturer. Some phones lack automatic rerouting, spoken turn-by-turn directions, and other advanced capabilities, which limit their usefulness while driving. We don't consider obscure third-party applications or hardware attachments.
4G broadband data Indicates which models are considered "4G" based on the definitions from the carriers. Check with your carrier to see which broadband data networks are available in your area.
This is a truly remarkable phone. It's fast and has a razor sharp display. It also comes with not one, but two voice assistants - one from Google, the other from Samsung.<br /><br />The device is fairly intuitive and easy to use. It's basically a small tablet, and very high functioning. It almost replaces a computer!<br /><br />My only quibble is that the controls on the side (volume and power) are sometimes tricky to operate. Other than that, this is a great phone!

Easy for first smart phone user
Brilliant Color Display
Accidental Power Off
Low ring tone
Its easy to shut off side power button in the middle of photo taking. Will only allow 1 or 2 photos to be attached to a text message. States the file is too big. I am new to using a smart phone. I previously owned a cheap flip phone that didn't have a dedicated qwerty screen. I am only just beginning to learn how many functions it has. I have a co-worker who owns one and am looking forward to a tutorial from him. Its like I jumped 20 years into the future overnight.

Best Smart Phone Available Right Now
Screen Washes Out In Day
I'm an Android guy (Especially once they're rooted) and also old enough that a large, hi-res screen is highly beneficial. I honestly can't think of a single thing this phone can't or won't do that any other phone will. My girlfriend has the latest iphone and while it's a very good phone I wouldn't trade under any circumstances.<br /><br />My old Motorola X was under-powered and would constantly crash or freeze up when I tried mult-tasking. The 4S has power to spare. I cannot make this phone lock up, even when I've tried. It simply will not crash or freeze up, period.<br /><br />More powerful battery than the 3S and the phone seems to be better at power consumption. It's solid, but it could still be better.<br /><br />Huge, but not too big, screen with great color and quality. The darn thing is still very difficult to see in bright daylight, though.<br /><br />Best smart phone ever up to this point, IMO.
