iOS7 goes for Public Launch on September 18

At iPhone media event, Apple CEO Tim Cook announced iOS 7's public launch date -- September 18, two days before the iPhone 5s and the iPhone 5c release. He also highlighted iOS 7's major redesign and the slew of new features the operating system will introduce, including Control Center, a revamped Notification Center, AirDrop, iTunes Radio, and new multitasking capabilities.

Take Better Pictures with iPhone Camera Grid

Turning on the iPhone camera grid makes it easier to take better pictures, here’s how to enable it:

    Launch the Camera app from home screen or lock screen
    Tap on “Options” at the top
    Swipe Grid to “ON”
    Tap “Done” to hide the Options again and return back to Camera

The grid will not appear on finalized images in the photo stream.

What’s the point? If you’re new to photography or don’t know why the grid is potentially useful, the grid makes composing images using the “rule of thirds” easier. Essentially that means by dividing a picture into horizontal and vertical thirds and placing compositional elements along those lines and intersections, you’ll end up with better pictures. It’s an old artistic technique that has been around for hundreds of years.

 

The animated gif shown above from Wikimedia demonstrates this well, and there is more information on Wikipedia if you want an in depth explanation of the technique and its usage in art and photography throughout history.

The grid option is available only to iOS devices with a camera using iOS 5 and later.

Apple iPhone 4S Review

The iPhone 4S is a marked improvement over last year’s model, ensuring that the iPhone continues to lead the smartphone pack in real-world experience, if not in increasingly meaningless specs.

After spending nearly a month testing the iPhone 4S, I’m confident when I say that not only is it a significantly better phone than the iPhone 4, it’s the best smartphone I’ve tested to date. Despite the fact that most upgrades in the 4S won’t be obvious to most users, the phone is a marked improvement over last year’s model, ensuring that the iPhone continues to lead the smartphone pack in real-world experience, if not in increasingly meaningless specs.



That said, there are two very visible enhancements in the iPhone 4S--context-aware voice recognition and an improved camera. But, the real win for Apple is the dramatically improved cellular antenna--since moving from the iPhone 4 (AT&T) to the iPhone 4S (also on AT&T), I’ve experienced a fraction of the dropped calls that I had before.

Reintroducing A5
What exactly is the real world impact of the iPhone 4S’s dual-core CPU? It’s about twice as fast in benchmarks--the Sunspider Javascript benchmark runs on the iPhone 4S in about half the time it takes on the iPhone 4 (both running iOS 5). In benchmarks, the jump from a single core, Cortex A8-based ARM CPU to a dual-core, Cortex A9-based ARM CPU makes a significant difference.

However, in most of the apps I tested, the performance boost is barely noticeable. Some applications launch faster on the 4S than the 4, but the delta is not something you’re likely to notice. I also tested a handful of apps that require more CPU power, and some were noticeably faster. For example, some panorama stitchers seem to do their business faster on the iPhone 4S than on the iPhone 4.

The A5 also includes an updated GPU, which Apple advertises as “up to 7x faster than the iPhone 4”. While this claim doesn’t hold up to benchmarks, the new iPhone delivers a noticeably smoother frame rate in some of the graphically intense 3D games I tested. This observation is backed up by benchmark scores from AnandTech, where the iPhone 4S shows roughly 2.3x better performance in AnandTech’s Unreal Engine 3 benchmark. As always, there’s a gotcha. Most iOS game developers use extra graphical horsepower to increase image quality, not improve framerate, so even though the hardware in the iPhone 4S is more capable, many games simply won’t take advantage of it.

Say Hi to Siri

Voice control in phones is nothing new, iOS 3 included a handful of voice commands, Android has had commands and dictation since Froyo rolled out last year, and Windows Phone 7 added voice support with the Mango update. Siri goes one step beyond these early offerings though, adding rudimentary natural language parsing to the voice control mix.

What is natural language parsing? It sounds deceptively simple, instead of recognizing a command or two for each task, Siri recognizes dozens of potential instructions for every task. More importantly, Siri is aware of context in a way that other voice control implementations aren’t--it has access to your complete calendar, address list, to-do list, location, music library, and more.

Most other implementations require one very specific phrase for each task, for example on Android I can say “call Norman Chan mobile” and the phone will call Norm’s mobile phone. However, Siri will recognize dozens of combinations of commands and variations on Norm’s name. This means that everything from a straight Android-style command to “Get Norm on the line” has the desired result. You can even assign relationships to people, so you can tell Siri to call your wife, best friend, mother, or son.

You can also use Siri to send and read text messages, send and read emails, make appointments, check your calendar, check the weather, set a timer or alarm, get directions, play music, and a whole host of other tasks. Some of these are very useful--I find myself using Siri to set timers while cooking and text while driving all the time--but the more complex your task, the more likely Siri is to break down.

For example, a simple “Tell my wife I’m on my way home” consistently works really well. When you try anything more complex than that, like using multiple sentences or proper nouns that aren’t in your contact list, Siri’s success rate goes way down. For example, I couldn’t get Siri to recognize “Wow, I didn’t know there were four Jaws movies” despite trying multiple times. Siri doesn’t handle edits particularly well either. You can’t make small, granular changes to any Siri tasks; instead your options boil down to accept, cancel, or do-over.

This highlights my first fundamental problem with Siri. It’s handy for basic tasks, like dialing a phone number, sending a simple text, or setting a timer, especially when I can’t safely look at the screen. However, as someone who works in an open area filled with co-workers, I’m not likely to use my phone at my desk. That leaves the car as the main place I use Siri, and it’s not ideal for that. Siri is very inconsistent with voice feedback, sometimes it reads text messages back without prompting, sometimes it expects me to look at a screen. Without turn-by-turn navigation in iOS, getting directions still requires me to look at the screen--it’s more dangerous than helpful.

However, my biggest problem with Siri is that Apple hasn’t made the service accessible so that third-party apps can hook into the service. That means I can’t use Siri to check Twitter messages, fire up my turn-by-turn navigation app, or find movie showtimes. There’s no fundamental reason this couldn’t happen--Siri is already using Yelp for local recommendations and Wolfram Alpha for specific types of queries. For me, the lack of third-party access earns Siri its “beta” tag, and renders it a nifty novelty, but nothing more, at least for now.

A Better Point-and-Shoot

The other immediately noticeable improvement in the iPhone 4S is its rear camera. The bump in the camera sensor from 5MP to 8MP brings not only larger photos, but clearer ones as well. That’s actually due more in part to the new five element lens in the 4S. We noticed improvements in both day and night shots; photos shot with natural light look less overexposed and photos taken in dark settings like bars or at concerts are less grainy than ones taken with the iPhone 4. The improvements are clearest in portraits and up-close macro photos--skin tones are more fleshed-out and the bokeh effect is gorgeous. And while some other smartphones (like the Nokia N9 and Samsung Galaxy S II) take better photos than the iPhone 4S in certain conditions, the camera here is much more than just “good enough” (in fact, all of the photos used in this review were taken with an iPhone 4S).

Additionally, the time it takes from tapping the camera app to actually being able to snap a photo has been greatly reduced. Apple wasn’t kidding when it boasted a shutter speed boost in the 4S. Whether that’s due to the extra processor horsepower in the A5 or the new camera sensor is irrelevant; I found myself missing fewer opportunities to take spur-of-the-moment [puppy] photos in everyday use. The case for smartphones replacing traditional point-and-shoots for everyday photos is stronger than ever--it actually takes less time to double-tap the home button, launch the camera app and be ready to take a photo on the iPhone 4S than to turn on a Canon point-and-shoot.

Improvements in photo quality transfer over to the video side as well. The iPhone 4S now captures 1080p video, with automatic image stabilization. While videos look really good, I’m a bit disappointed that there is no built-in ability to adjust video capture settings with the default camera app. 1080p video consumes a lot more space than 720p ones--a five minute video takes up almost a gigabyte of space. You can bypass these restrictions with third-party apps, of course, but it would be nice with Apple built those options in, even as “advanced” features hidden in Settings.


Does Size Matter?

Like the iPhone 4, the iPhone 4S features a 3.5-inch, 640x960 pixel screen. The display is a little warmer and brighter than the iPhone 4’s screen, but you won’t notice that unless you compare them side-by-side, and even then, it’s a little tough to see. No, my only question about the iPhone 4S’s screen is “Is it big enough?”

Over the last year, Android vendors have begun an insane screen size arms race, culminating in the imminent arrival of Google’s own Galaxy Nexus, which sports a crazy 4.65-inch screen. Admittedly, the phones with larger screens are significantly thinner than the iPhone 4 and 4S, so the larger-screened phones don’t really have a bigger impact in your pocket.


I’ve seen several apologetic stories over the last few weeks rationalizing Apple’s 3.5-inch screen size, but I think the real answer is simpler than thumb-size. Because iOS requires that app developers design their apps for specific resolution, Apple isn’t likely to add another intermediate screen resolution for developers to support, at least until the 3GS’s 320x480 resolution is retired in a few years. So, all a larger iPhone screen would do is decrease pixel density and reduce image quality. It wouldn’t actually impact the number of lines of text you can fit on a screen, the number of emails you can see at once, or the amount of data an app can pack on the screen. In fact, the only core applications that would benefit from a larger screen are--you guessed it, web browsing and games.

So that’s why I think the iPhone 4S retains its 3.5 inch screen, while Android phones grow ever larger. While I wouldn’t object to a larger iPhone screen, I don’t want a bigger screen unless Apple increases the resolution at the same time. The iOS browser works well with the small screen, mainly because you can double-tap to make a column of text full screen. Still, more screen space could have a huge impact on both web browsing and game play. As it is today, I prefer both on the iPad.


I Can Make Phone Calls!

Apple made significant updates to the iPhone 4’s antenna design for the 4S, adding a second antenna and moving the “deathgrip” spot from the bottom of the phone to the top. There are many variables dealing with cellular service outside our control, which makes it difficult to say with certainty, but in our side-by-side testing, the iPhone 4S seems to be a much more reliable phone than the original GSM version of the iPhone 4.

I tested the iPhone 4S on AT&T to the iPhone 4 on AT&T in several different scenarios at various times since the phone’s launch. My three scenarios are:

•     Downtown San Francisco in a high-signal, densely-populated area
•     At my home, which is plagued with spotty coverage, especially indoors
•     While driving my 26-mile daily commute

Additionally, I used the iPhone 4S as my primary phone. While my results were consistent with my testing experience, it’s important to note that the sample size is small enough that it should be considered anecdotal. Extended coverage testing is outside the scope of Tested.


Whether testing indoors in a low-signal area or on our commute home through San Francisco, I experienced fewer dropped calls on the iPhone 4S than on the iPhone 4. In six side-by-side testing sessions, the iPhone 4 dropped a total of six calls, while the iPhone 4S dropped none. In a month of daily use, I experienced two dropped calls while using the iPhone 4S--once while driving through a tunnel and the other while parked at a red light. The iPhone 4 repeatably drops calls at two points on my normal commute route, while the iPhone 4S does not. In the AT&T dead spot that is my house, I can walk through the house while on the phone with the 4S, which inevitably results in dropped calls on the iPhone 4.This aligns with our experiences using other phones on AT&T, which experienced a fraction of the connection problems that the iPhone 4 did. Hopefully the iPhone 4S means that the days of poor antenna design are now behind Apple and its phones.


The Verdict

The iPhone 4S, unlike its predecessor, is almost entirely controversy-free. Yes, there was a gnarly iOS 5 bug that drained some users’ batteries, but it affected all iOS devices and Apple has fixed the problem for most users. As it is today, the iPhone 4S is the best smartphone you can buy, period. The camera is impressive, the phone is speedy to the point that you’ll never notice how fast it is, the battery lasts all day, the screen looks fantastic, and the antenna problems seem to be fixed.


Everything else I praised in last year’s iPhone 4 review remains true. The app ecosystem for iOS remains the gold standard for both quality and quantity, and the overall user experience for iOS is unparalleled. With the additions that came with iOS 5--a modern notification system, PC-free setup, minimal reliance on iTunes, iCloud support, and more--there’s absolutely no reason to apologize for owning an iPhone. Yes, Siri is a gimmick. But even in beta form, it’s worth noting that I’ve actually used Siri more in a month than I’ve used the voice recognition software on every other device I’ve tested.
