Samsung Galaxy S4 official: 5-inch 1080p screen, cutting-edge specs, coming in April

Share this story

Samsung has officially announced the Galaxy S4 at its Radio City Music Hall event in New York City. JK Shin, Samsung's head of mobile communications, teased a number of the leaked features that we expected to hear and then finally introduced the new handset, which looks just like what we saw in earlier leaks. The phone will launch on 327 mobile operators in 55 countries starting at the end of April, with 3G and 4G / LTE versions available, and its polycarbonate case will initially be available in two colors, white and black.

The 5-inch screen features a 1080p resolution, as expected, is covered with Corning's Gorilla Glass 3, and it's known as a "full HD super AMOLED" screen with 441 pixels per inch. The phone comes with 802.11ac Wi-Fi (which also runs on the standard a/b/g/n bands), Bluetooth 4.0, and Cat 3 100 / 50 Mbps LTE, and also comes with an IR blaster like the HTC One. Key specs include a removable 2,600 mAh battery, 2GB of RAM, and 16, 32, or 64 GB of storage. Also of note is the new processor — either a Samsung Exynos 5 or Qualcomm Snapdragon S4 Pro 600 processor, depending on the region. (Update: we learned the day after Samsung's event that the Qualcomm processor Samsung is using was not the Snapdragon S4 Pro but the more powerful Snapdragon 600.)

The leaks were accurate this year

Samsung is also touting its new 13-megapixel camera (the front camera is 2-megapixels), which the company says can take more than 100 shots in four seconds and then select some to composite into a single frame — the company says this will help eliminate photo bombs. It also has a "Sound and Shot" feature that lets you record five seconds of audio before you take a photo. Another unusual camera feature is the "dual camera" mode, which takes shots with both the front and back cameras and integrates them into a single scene.

There's a whole host of other new software features on top of the Android 4.2.2 Jelly Bean OS, as well. As rumored, there are a few eye-tracking features on board. "Smart Pause" lets you pause a video simply by looking away, with it resuming when you look back, while "Smart Scroll" lets you move through emails or web pages without looking at the screen — Samsung says the phone recognizes your face looking at the screen as well as the movement of your wrist and moves the content to match your movements.

Other software updates include S Voice Drive (optimization for voice commands when you're driving), Optical Reader (which can scan your business cards and the like and provide useful actions like calling a number or translating the text), and WatchOn (which takes advantage of the IR blaster to use your phone like a remote). And as CNET reports, the phone will have a new swipe-to-type keyboard, courtesy of SwiftKey. There's even a feature called Group Play, which syncs multiple phones to use them as stereo speakers for music playback. Group Play also can share other content (like photos, documents, and games with your selected friends — without needing a dedicated network.

There's a baffling collection of new software here

One of the more interesting software additions is S Health — Samsung's clearly been paying attention to the wearable computing trends. The phone's sensors can monitor your fitness level and surroundings, making it a full-fledged fitness tracker — it'll integrate with a number of Samsung accessories, as well. The phone features a built-in pedometer for tracking the number of steps you take — or run — during the day, much like Fitbit's line of devices. However, sensors in the phone also allow it to measure the ambient temperature and humidity of the room you're, all of which feeds into the S Health app itself. Diet tracking is integrated as well, with the app pulling able to pull caloric information from a database of common food items.

Samsung also added some touch-free gestures to the Galaxy S4: Air View and Air Gesture. The former lets you hover your fingers over the screen to pull out contextual data or preview the content of messages, while the latter lets you control features like your music, answering calls, or scrolling without having to actually touch the screen. Samsung also debuted a couple of new accessories, including a new Xbox-like Bluetooth gaming controller and wireless charging cases, which support either the PMA or the Qi charging standard.

Overall, it's a rather shocking amount of new software and features — time will tell how much of this gains traction with users. There's no word on how much the Galaxy S4 will cost yet, but it'll be available in Q2 on Verizon, Sprint, T-Mobile, AT&T, US Cellular, and Cricket in the US. As for Europe, it'll be coming to carriers including Deutsche Telecom, EE, H3G, Orange, Telenor, Telia Sonera, Telefonica, and Vodafone.

Doing more with less (extravagant holiday parties).

Sundar Pichai addressed employees’ questions about Google’s spending changes at an all-hands this week, according to CNBC.

“Maybe you were planning on hiring six more people but maybe you are going to have to do with four and how are you going to make that happen?” Pichai sent a memo to workers in July about a hiring slowdown.

In the all-hands, Google’s head of finance also asked staff to try not to go “over the top” for holiday parties.

Japan will fully reopen to tourists in October following two and a half years of travel restrictions.

Good news for folks who have been waiting to book their dream Tokyo vacation: Japan will finally relax Covid border control measures for visa-free travel and individual travelers on October 11th.

Tourists will still need to be vaccinated three times or submit a negative COVID-19 test result ahead of their trip, but can take advantage of the weak yen and a ‘national travel discount’ launching on the same date. Sugoi!

Sony starts selling the Xperia 1 IV with continuous zoom lens.

What does it cost to buy a smartphone that does something no smartphone from Apple, Google, Samsung can? $1,599.99 is Sony’s answer: for a camera lens that can shift its focal length anywhere between 85mm and 125mm.

Here’s Allison’s take on Sony’s continuous-zoom lens when she tested a prototype Xperia 1 IV back in May: 

Sony put a good point-and-shoot zoom in a smartphone. That’s an impressive feat. In practical use, it’s a bit less impressive. It’s essentially two lenses that serve the same function: portrait photography. The fact that there’s optical zoom connecting them doesn’t make them much more versatile.

Still, it is a Sony, and

If God sees everything, so do these apps.

Some Churches are asking congregants to install so-called “accountability apps” to prevent sinful behavior. A Wired investigation found that they monitor almost everything a user does on their phone, including taking regular screenshots and flagging LGBT search terms.

Shutterstock punts on AI-generated content.

Earlier this week, Getty Images banned the sale of AI-generated content, citing legal concerns about copyright. Now, its biggest rival, Shutterstock, has responded by doing ... absolutely nothing. In a blog post, Shutterstock’s CEO Paul Hennessy says there are “open questions on the copyright, licensing, rights, and ownership of synthetic content and AI-generated art,” but doesn’t announce any policy changes. So, you can keep on selling AI art on Shutterstock, I guess.

This custom Super73 makes me want to tongue-kiss an eagle.

Super73’s tribute to mountain-biking pioneer Tom Ritchey has my inner American engorged with flag-waving desire. The “ZX Team” edition features a red, white, and blue colorway with custom components fitted throughout. Modern MTBers might scoff at the idea of doing any serious trail riding on a heavy Super73 e-bike, which is fine: this one-off is not for sale. 

You can, however, buy the Super73 ZX it’s based on (read my review here), which proved to be a very capable all-terrain vehicle on asphalt, dirt, gravel, and amber fields of grain.

The sincerest form of flattery.

I had little interest in Apple’s Dynamic Island, but once a developer built their spin on the idea for Android, I had to give it a try.

Surprisingly, I’ve found I actually like it, and while dynamicSpot isn’t as well-integrated as Apple’s version, it makes up for it with customization. Nilay’s iPhone 14 Pro review asked Apple to reverse the long-press to expand vs. tap to enter an app setup. In dynamicSpot, you can do that with a toggle (if you pay $5).

The Twitter employee who testified about Trump and the January 6th attack has come forward.

This summer, a former Twitter employee who worked on platform and content moderation policies testified anonymously before the congressional committee investigating the violence at the US Capitol on January 6th.

While she remains under NDA and much of her testimony is still sealed,  Anika Collier Navaroli has identified herself, explaining a little about why she’s telling Congress her story of what happened inside Twitter — both before the attack, and after, when it banned Donald Trump.
