Awesome phone, incremental upgrade from SIII

By rpv

Galaxy S4 is an incredible phone. I have been using this unlocked S4 for past 2 days helping a friend to migrate from iPhone 4S. My friend has been on iPhone and it also gave me a unique perspective. I used iPhone for couple of years and been using Android for past 3+ years.

I have used Galaxy S3, Note II and for me S4 is more like a S3s :) If you have a Galaxy S3, it is perfect and there is no need to move to S4. The new features are more like minor upgrades for me. Just like Detroit rolls out new cars every year, phone manufacturers have found excellent way to make yearly upgrades.

Battery came for almost a day. The video playback was crisp and my friend was amazed at the customization options. It is heaven for a iphone user to come out of shackles and explores the wonderful world of Android. It sure sounds like it is for geeks, but Samsung has created lot of ways to simplify and make it less intimidating. The EASY mode is for one such reason. Samsung's addition of all those apps (commonly referred as crapware) is not as bad as HTC or LG. Android experience is classified as pure vanilla in phones like Nexus. Vendors like Samsung have added a whole lot of extra programs.

5" HD Super AMOLED 1920 x 1080 display (441 ppi) is just plain gorgeous. 13 MP camera takes ginormous image sizes. I put a 64 GB microSDXC card SanDisk 64GB Mobile Ultra MicroSDXC Class 6 Memory Card with SD Adapter - Retail Packaging as my friend wants to take lot of movies (built-in 2 GB RAM, 16 GB ROM). No stuttering, and very smooth playback of videos captured in varying light conditions (HD Playback; HD Recording). Compatible video types are AVI/DIVX, WMV/ASF, FLV, MKV, MP4/3GP, WEBM. HDR and Panaromic photos were incredibly sharp. Compatible audio types are: AAC, AMR, MP3, OGG, WMA/ASF, 3GA/M4A, FLAC, WAV. Google Music, PlayerPro Music player are producing excellent music. Audio/Video is one section where S4 has nudged S3. For a normal user, if you are not into lot of video processing this does not matter.

S4's infrared sensor is the same technology as TV remote control, so with WatchON you can change the TV channel from your phone. My friend was shocked to see this feature. Having used Android for a long time, I explored all new features one by one. My friend is still getting used to and feels this is too complicated. I broke down into lot of sub features and told my friend he may not use 50% of features, but told him to explore one feature at a time and focus on that.

Games were very buttery, this phones runs ARM®-based octa-core mobile CPU. This is apparently world's first! Inside this chip is Imagination Technologies' PowerVR SGX544MP3 GPU. I tried several car racing games and performance was phenomenal. People on the XDA-Developers forum report seeing smearing and ghosting when scrolling on the phone. This especially occurs to people when scrolling among darker colors, which begin showing up as purple. I tried hard to see if I could on the S4 I was testing with my friend and I could not see it. I am sure these can be upgraded with software over due course.

Air View and Air Gestures - are they worth it? Air view is similar to how the S-pen on the Galaxy Note 8 works. Simply hover finger a few millimeters above the screen and in supported apps, you'll see a preview of content. This works with many of Samsung's built-in apps, including the photo gallery, the dialer, Samsung's browser and email client. It also works with Flipboard. Air View works by cranking up the capacitive sensor on the screen. Another new feature is Air Gestures. This uses the IR sensor on the top of the phone to detect movement by your palm or finger. One can flip between open tabs in Samsung's browser app, skip to a new song in the music player and do many other things. I say these are still in works and sometimes not very efficient.

GPS was spot on and I tried multiple GPS apps. It was bright outdoors (had to crank the brightness all the way up). I tried multiple apps to demonstrate to my friend. In the end, my friend was impressed with what all Android and in particular S4 had to offer. Smooth and Stunning display!

I tried following apps and they just worked awesome.

Just ok.

By Yo daddy

Ever since I watched the Samsung Galaxy S4 launch at "Radio City Music Hall" I've wanted this phone. They made the gesturing and eye tracking look so awesome! However both are difficult to use, and cut my battery life in half. I tried to impress my friends with the hand/eye features, but just ended up looking dumb when I couldn't get them to work consistently.

Maybe it takes practice, I don't know.

My phone stayed hot too. (even when idle) I finally had to disable them or else keep charging my phone twice a day.

Why would I buy a phone for features I can't even use?

Some other observations.

The screen is awesome!

The call quality is good.

The camera is good, but not great.

The phone is VERY light.

The battery life is normal with all the bells and whistles turned off.

The phone has the same glitchy-ness found in all Android phones. In fact, I've had to restart it three times in the four days I've had it just for setting changes to show up. I also had one lock up.

I bought mine directly from VERIZON, but they won't accept my review despite re-writing it several times. (maybe because it's not 5 stars)

Don't get me wrong, it's a nice phone, but I can't use the things I bought it for!

I wanted to like this phone so bad, but I find myself just disappointed.

a few days later.......

I've been tinkering with it a bit more, watching the "top of screen icons". As I do, I've noticed that the phone is constantly looking for my face (or any movement) Even when I am not directly in front of it I can see it reacting to other things going on in the room. Certainly this is the cause of the battery drain. I imagine that battery technology just isn't ready for total hands free phone use. Don't get me wrong the phone has a lot of great qualities, and I'm sure that anyone who buys it will enjoy their new phone. Personally, I am a big fan of Samsung products. Ever since I watched the Samsung Galaxy S4 launch at "Radio City Music Hall" I've wanted this phone. They made the gesturing and eye tracking look so awesome! I just want anyone reading this to know that some of those features have limitations.

Samsung S4 sets the bar to a new level

By Paul S. Remington

The Samsung S4 cell phone is the hottest and newest phone on the smart phone market. This Android device has gotten much press and rightly so. In terms of specifications, the S4 has a lot going for it that has it as the leader of the pack over many smart phones. But at first glance, this new phone looks and feels much like its predecessor, the Galaxy S3. So what makes this phone different and why should you be interested in purchasing it? This review will explore those issues and help answer that question.

When you have a good thing going, why not start with that as your baseline. Samsung has done just that with the S4. The S3 and the S4 are very similar on many levels and very different in key areas. Their size is essentially the same at 5.38" x 2.75" x .31". This actually makes the S4 .7mm thinner than the S3. Its weight is 4.6 ounces, .7 ounces lighter than the S3. Comparing the two, Samsung has increased the size of the screen to a 5" display that offers full HD resolution at 1920 x 1080 pixels. While other phones offer similar resolutions, none have the same quality image that comes from the Super AMOLED screen offered on the S4. Side-by-side comparisons with phones such as the HTC One find the S4 shines with more prominent resolution and richer color tones.

The screen also has improved capacitance over the S3 and previous Samsung offerings. This improved capacitance supports phone use while gloves are worn. Those who live in cold climates or those who are fashion conscious and wear gloves will find this enhanced capability helpful. While this capability is a nice addition, it takes some getting used to. Because it is more sensitive, it's easy to falsely register a finger press if you hover your hand over the screen in the just the right way. Hopefully Samsung can correct this performance flaw with future software upgrades.

Regardless, the S4 screen is a remarkable technological creation. Its visual performance makes it like a smaller cousin of much larger HD televisions. It is a beautiful piece of work and the highest quality screen of its size presently on the market.

At first glance, the camera appears to also be the same as the S3. This is, in fact, not the case. The S4 houses a whopping 13-megapixel, rear-facing camera and a 2-megapixel, front facing camera. The rear-facing, 13-megapixel camera image is excellent. The imaging capabilities of both cameras extend past the raw hardware with added features built into their associated software. There is software to do most anything you can think of with the images taken. Software even uses both the front and back camera to offer all kinds of imaging effects from panoramic images to slow motion videos.

Much of the new hardware, software, and extended features built into the S4 place heavy processing demands on the phone's engine. Because of this, Samsung has integrated a 1.9GHz quad-core Qualcomm Snapdragon 600 processor to help keep things purring along smoothly. At the time of this review, this makes the S4 one of the fastest smartphones on the market.

Coupled with this increased processing power is an expanded memory card slot for additional storage. Samsung is selling the S4 in 16GB, 32GB, and 64GB configurations. For those considering the S4 with 16GB of storage, this may be a bit limiting. Approximately 6GB is eaten up by the OS and installed apps, which leaves a scant 8-9GB of storage. This is 2GB less storage than the S3. The S4 supports the installation of up to an additional 64GB using a Micro SD card. If you're considering purchasing this phone, you might want to add a Micro SD card to your purchase and expand the base memory, or purchase an S4 with a higher amount of integrated storage.

Keep in mind that the more data you add to your Micro SD card, the more information the S4 has to parse. If you have a 64GB SD card packed with pictures and videos, when you open the Gallery to view them, even the quad-core processor will crank itself silly to host them for you; it will take time for them to display. There's no working around this. It's the nature of the beast. Just accept this as a current limitation based on processor speed and storage mass.

The front of the phone contains a number of additional sensors that monitor eye movement and proximity so the phone knows how far it is from your ear. An infra red blaster is integrated into the top of the phone to enable it to act as a remote, with the appropriate app installed to function as a remote. These sensors and the infra red blaster offer many new features not available with the S3. The phone can act as a remote control for your television, CD/DVD player, A/V receiver, and even home appliances that support remote control. The eye sensor offers additional features that control screen dimming and auto pausing when you look away from the screen. Likewise, when you look at the screen, dimming and auto pausing resume their normal operation.

Applications available to support the additional sensors include Air View, Air Gesture, and Smart Scroll. While these features are futuristic and helpful in theory, they aren't flawless in practice. They are also rather complex to learn and use, which detracts from the concept of simplicity when it comes to operating the device. Take this into consideration when adopting the phone for your use. Not all the features have to be used at once. You may find some features helpful while others are an annoyance. They are all highly configurable and it will take some time and practice to set them up to your liking.

Like the S3, the S4 supports Samsung's S Beam and near field communication (NFC). S Beam allows two Samsung phones to be placed back-to-back so they can share multimedia content such as videos, music, pictures, etc. The devices only need to be placed a few centimeters from each other to link, and, unlike Bluetooth, no pairing is needed. Communication is provided by WiFi Direct, which makes transfer speeds quite good.

Samsung has received many user complaints over the quantity of polyurethane used with their phones. They are plastic centric in construction and many consumers feel this detracts from a robust, solid feel. The S4 seems to have taken this into consideration with the addition of a flat metal bezel around the side edge of the phone. Much like the iPhone, the S4 has a metallic edge that augments its former plasticized edge construction.

The case itself is similar to the S3. The rear cover is easily removed to reveal the battery, SIMM card, and Micro SD card.

As for battery life, the S4 stock battery is 2,600mAh compared to the 2,100mAh S3 battery. This is a 20% increase in battery size with no added thickness to the phone's form factor. In fact--as stated earlier--the S4 is .7mm thinner than the S3. This added battery storage is required due to the increased screen size and additional features and applications. Each person's use is highly personalized, so it's difficult to gauge how this battery will perform with your personal use, but, in general, it seems to be an adequate amount of power storage for moderate use. Still, it will more than likely require daily charging. If this is a concern to you, you might consider an extended-life battery. These batteries are freely sold on Amazon and other locations, but most of them require an aftermarket back to the case that will replace your stock rear cover. Extended batteries mean heftier weight and added thickness to the phone. Another option is to purchase an additional battery as a backup for when your primary battery discharges.

Out of the box, the S4 comes equipped with Android Jelly Bean 4.2.2 and a huge amount of software. If there's one complaint about this phone it is in relation to the amount of features and software bundled with it. The S4 has a mountain of software that, at first glance, can be absolutely overwhelming. It will take time to sort out and learn everything this phone can do, so pencil in an evening or two to explore, configure, and learn what's new and how to use it. The list is far too extensive to cover in this review, but it should be stated that every feature the phone has is supported by associated software. In addition to this software, Samsung has packed new applications to satisfy every possible type of user. You may find it all useful, but this is doubtful. Most likely, you'll use a subsection of all the software installed and make it your own. One could say Samsung has given the consumer the benefit of choice by adding so many features and so much software. Sometimes it's better to have too much than not enough, and this is true here. Rather than be overwhelmed by it, see it as a library of possibilities that supports a healthy amount of functions. Decide which functions are useful to you and learn them. For those functions and applications that hold little interest, leave them alone for now.

The S4 is an enhanced deconstruction and reconstruction of the S3. If you currently own the S3 and are considering an upgrade, take stock in the added features and capabilities of the S4. The S4 will give you the latest Android has to offer; a larger amount of storage space; a fabulous HD screen; a high-quality, 13-megapixel camera; huge amounts of added features and software; and a fantastic processor under the hood. If these things are important to you, then the S4 may be an exciting upgrade. If you're happy with the features and performance of your current S3, then you may want to save your money and stay with what you have.

Overall, the S4 is a brilliant device. It's not without its flaws and there is always room for improvement. While Apple performed wonders defining the modern smartphone, Samsung has helped take the concept one step further. If you're looking to upgrade your older smartphone and break into the Samsung Galaxy world for the first time, the S4 is a fantastic selection. It is, arguably, the best Android phone on the market, at present. Some may say it's the best smartphone, period. Each person's decision and opinion is highly individualistic. One thing is for sure, Samsung has pulled out all the stops to ensure consumers get the most for their money, and they have set the bar even higher for newcomers to take the mantle of achievement to a new level.
