With more features than Batman’s belt has gadgets, the do-anything Samsung Galaxy S4 is an elegant, powerful smartphone as likely to confound as it is to amaze.

The flagship in Samsung’s lineup and easily one of the best Android phones on the market, the Galaxy S4 can tell where you’re looking (and turn the page for you), translate over a dozen languages in real time, make you a pro photographer, help you lose weight, and more.

And to support so many features, this phone has menus and buttons galore. Indeed, it has so many menus, it’s menus actually have their own menus.

Samsung has thrown so many features into its new phone that the company actually bakes in an “Easy mode” that simplifies the interface down to a handful of easy to read items. You can turn the world’s smartest phone into the world’s dumbest, in other words.

While the simplicity of such a mode is likely to be a godsend for new smartphone users and those flustered by features -- I found it to be a breath of fresh air -- those willing to dive into the deep end of the feature pool will be rewarded with some impressively powerful tools that the company has made clear efforts to make intuitive.

And it has more tools than a carpenter, thanks to the most powerful hardware you’ll find on the market today. The 5-inch screen takes up most of the 5.38-inch phones frame, and will dazzle you. While enormous, the body is thin and fits pleasingly into the average palm. Some may prefer the iPhone’s all-aluminum body, but plastic is fine with me: It’s durable, lightweight, and knocks a few bucks off the cost.

A 13-megapixel camera (how big is your standalone digital device?) and some wonderful software are a clear standout feature. A new mode menu brings up a carousel with simple terms for a variety of different modes: Sports, Panorama, Night, Animated photo, Best face, and so on. Select one and a message pops up telling you just what it does (“Select the best picture of each person from 5 consecutive pictures to get the best merged group picture.”)

And, of course, there are options galore.

Can’t get Junior to sit still with you long enough for a nice photo? You can use the front and rear cameras at the same time to add yourself to the shot, in a variety of styles.

Want to get artistic? Take a series of pictures as your child takes the winning shot on goal or dismounts the balance beam -- the resulting image shows a static background with 4 or 5 sequential action shots. Or erase passers-by from a crowded setting; shots from that last Disney vacation never looked so good.

Grab a Galaxy S4 and the phone will likely be the best point-and-shoot digital camera you’ve ever owned.

S Translator is another powerful tool, one very similar to the Google Translate app. It can translate speech to and from a variety of languages in more or less real time, as long as you’re online of course. It can do the same for text, and ties into the email app.

This is both amazingly practical and fun. Playing around with the Galaxy S4 over the last few days, I’ve translated menus and secretly insulted people in German.  Sie wünschen ein Stück von mir? Gutes Glück, harter Junge!

S Health is another promising bit of innovation. This tool helps you set and keep fitness goals, count your footsteps and more. Look for more details about this, as well as an array of accessories such as heart rate monitors and pedometers, in May.

Many of the science-fiction features in this phone are more likely to frustrated and irritate than simplify life, however. An eye tracking feature meant to automatically scroll the page for you didn’t work well in testing, and getting back into the menu to disable it was an exercise in annoyance: Samsung has added a submenu to the row of status icons atop a standard Android phone to control its myriad features. But which of the 19 icons and catchy names controls this scrolling thing? I’ve got no idea.

Air Gesture is likewise a fascinating piece of tech you’ll never need. Thanks to yet another sensor on the front of the phone, you can page through emails, photos, and webpages by passing your hand over the phone. But why would you?  Air view, which shows information when you hover a finger over the screen, is somewhat more useful. You can see the contents of an email by hovering over it, or details on the day’s events -- or you could just open the email or calendar item, of course.

The features list goes on from there, ad nauseum. Multiple people can play the same tune simultaneously, for a surround effect. (This was impossible to test, of course, but sure seems gratuitous.) An integrated infrared camera lets you control your TV with the phone. S Note is Samsung’s integrated memo pad. Etc. and etc.

All these features, cameras and sensors tax even this phone’s giant 2,600-mAh battery. Turn off those you aren’t using and you’ll get a surprisingly reasonable battery life. And the promise of countless apps to play with mean this phone is likely to keep entertaining you for weeks to come.

Just take a minute to watch where you’re walking, ok?

This smartphone knows when you’re going to die -- and could save your life

Heart attack coming on? Yep, you guessed it: There’s an app for that.

A new medical device could turn your phone into a lifesaver; the tiny implant monitors your blood and can send a warning to your smartphone if it detects potentially life-saving problems.

The device, developed by a team of scientists at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland is the world’s smallest such implement ever; using Bluetooth, it transmits data to your phone and could even warn you if you’re about to have a heart attack.

Often in the moments before a heart attack, fatigued or oxygen starved muscles begin to break down, and fragments of a heart-specific smooth muscle protein --  triponin -- are dumped into the blood. If this can be detected before disruption of the heart rhythm or an actual heart attack, lifesaving pre-emptive treatment can arrive in time to save a life.

The device can also track levels of glucose, lactate and ATP providing valuable data for physiological monitoring.

Outside the body, a battery patch provides the 100 milliwatts of power the device needs, sucking juice via wireless inductive charging off the skin.

Dr. Leigh Vinocur, from LSU Health Science Center, told Fox News the implant has many potential uses, including monitor glucose levels for diabetics and helping prevent deaths from heart disease. But the connection to the smartphone may prove problematic.

“What happens if you’re in an area where there isn’t good cell service? It’s not that reliable right now. Is it 4G, is it 3G?” she said.

The other challenge for the device, which has yet to receive FDA approval, is in the monitoring style. Simply put, Triponin may not be the most effective way to gauge when a heart attack has occurred.

“The chemical is first released 4 hours after a heart attack and peaks at 16 hours after. And sometimes that’s very late and it means the muscle is already damaged,” Vinocur told FoxNews.com.

She said other devices being looked at study heart rhythms and can detect more immediately when when a clot has formed. Those devices rely on pagers and the individual person to call 911 for help -- a smarter system than relying on the wireless connection from a smartphone.

“Sometimes when time is critical, you do have issues: are you going to have service in that area?”

The 7 deadly sins of smartphone users

Everyone is guilty of the occasional indiscretion on a mobile device. But don't be too hard on yourself — smartphones have been a part of people's daily lives for a relatively short time. In terms of mobile experience, smartphone users are just entering their teens, and breaking rules is part of the maturing process.

Results from "Truth About Connected You," a worldwide study of 9,000 mobile users published today (March 1) by consumer researcher McCann Truth Central, concludes all users are just teenagers when it comes to mobile.

"Like most teens, we're taking risks and trying new things," Laura Simpson, the company's global director, said. Consumers have owned 6.4 devices and entered into a serious relationship with a new mobile device or provider every 22 months over the past 12 years, according to the report. 

Chalk it up to lack of experience or the thrill of breaking rules, but either way, most mobile users have committed one or more transgressions through their devices. McCann dubbed these the seven deadly sins of mobile:  

1. Lust

Phone in hand, sometimes the temptation to send a racy text or sexy photo is just too much to resist. More than one in 10 people say they have received a so-called sext. (The American Association of Retired Persons even offers advice on sexting.)

2. Gluttony

Look around any restaurant, and you'll see quite a few phones on the tables or in people's laps (a technique used by more-discreet diners). People can't let their phones out of sight. In fact, 38 percent of respondents said they use their devices in the bathroom. 

3. Greed

There's an awful lot of free, legal entertainment online, but many want more. Copyright laws haven't stopped 29 percent of people from downloading illegal content (nearly 50 percent of respondents in China do it).

4. Sloth

Don't feel like talking? Can't be bothered with another text? More than half of the mobile users in the survey said they've purposely ignored calls and texts.

5. Wrath

Confrontation has become easier with phones, and the temptation to send off a quick "WTF" to express anger is not unusual. Two out of 10 people said they use "mofanities," (mobile profanities). And emojis make it all that much easier; how many times have you sent an angry face, steaming devil or grimacing cat?

6. Envy

In the old days, people judged others by their shoes, but today it's all about the phone. That's undeniably one of the reasons millions upgraded their iPhone 4S to the 5; they know their friends are watching and judging. In the survey, 55 percent said they judged others by their choices in device.

7. Pride

Call it pride or entitlement, but 44 percent of people said they have a right to do whatever they want with their mobile devices, even if it bothers someone else. Taking flash photos in restaurants, texting at the dinner table and listening to music with headphones when you're with friends, are just some of the annoyances phone users indulge in.

Maybe people aren't as grown up as they thought they were, and it just takes an iPhone to bring out their worst. How many of these mobile sins have you committed? Tell us below.
