Apple showcases colorful 5S, 5C iPhones; rolls out iOS 7 update


As expected, the 5S and the 5C iPhones were unveiled on Tuesday, Sept. 10 with a splash of colors.

In the past, a new iPhone announcement was always a magical moment, thanks to all the hype created Apple Inc., the media and Apple fans all around the world. The magic continues with these two devices.

The initial excitement surrounding iPhone announcements started on Jan. 9, 2007, at the Macworld Conference & Expo in San Francisco, when the late Apple CEO Steve Jobs pulled an iPhone 2G out his pocket. The hoopla surrounding Apple smartphones announcement has been gaining traction every since and there seems to be no end in sight. The true Apple fans can probably name them all, starting with the 2G in 2007, the 3G in 2008, followed by the 3GS in 2009 and the 4G in 2010. We're not done. Then we had the 4S in 2011 and the evolutionary, if not revolutionary, iPhone 5 just a year ago.

Now we have the iPhone 5S, a souped-up doozy of a device with fingerprint reader technology and a 64-bit A7 processor with a 8 megapixel camera has set yet another standard for processing power in mobile devices. Gamers will rejoice, especially if the A7 chip finds its was into future iPads. The 5S will be available in new colors – gold, silver and "space gray" – to go with all that processing power.



The 5C, a colorful cheaper device for emerging markets, will be a fashion statement, with five color cases to choose from. Depending on what mood you're in, you can choose from green, blue, yellow, pink and white. It'll have a 4-inch Retina display and Apple's A6 chip.

The fingerprint sensor technology, which Apple is calling "Touch ID," sounds like a winner, because I, for one, have too many passwords to remember anyway. That feature alone would be worth an upgrade from an older iPhone if I had to do was press the home button to wake the phone and get busy.

I find it surprising that there was no mention of the new iPhones having the Near Field Communication technology, now commonly known as NFC. Apple has stayed away from this short-range wireless communication technology, while other manufacturers, such as Samsung, Nokia, HTC and BlackBerry have been incorporating this feature into their devices since early 2012. Now that NFC Tags and mobile payments are becoming more popular, I can't see Apple staying on the sidelines much longer.

As Apple moves past traditional white and black devices, the gold color for the 5S, the flagship device, attracted the most attention, but I'm not likely to rush into the store for a color change. My black iPhone 5 is serving me well. But iOS 7 will be available for download Sept. 18 and I'll be first in line for the update.

We can kick this news of the latest iPhones around for hours and never get tired, so let's talk pricing. The iPhone 5S is $199 under contract for the 16GB, $299 for the 32GB and $399 for the 64GB, while the 5C starts at $99 for the 16 gigabyte model and tops out at $199 for the 32GB model. Both iPhones will be available Sept. 20, so it will be time to start lining up soon.

HTC Desire 600 - dual SIM device review



The HTC Desire was HTC's well known flagship in 2010, since then their flagship brand was replaced by the One series, however due to its successful history the Desire name is still being used for the mid to low end range releases. If you want the short version of this review: The best thing about the Desire 600 is the build quality, it's a mid-range premium phone.

A Mid-Range Premium

Shortly after the release of the One, HTC announced the Desire 600 dual sim with many of its big brother's features - mainly HTC Sense 5, Blinkfeed and Boomsound. It also includes Video Highlights, but omits the Infra Red blaster and Ultrapixel sensor (2.0µm). Instead, it's replaced with a standard 8MP BSI camera sensor (1.4µm) and the first version of the HTC ImageChip - this also means that the Zoe features are lost in the process. It joins the fleet of other HTC dual sim specialists like last year's Desire SV and One dual sim (limited to specific markets).

Design & build quality

Being mid-range doesn't prevent it from carrying HTC's renowned build quality and in fact the device has some impressive highlights: the screen is protected by a robust metallic frame which also houses the dual speaker grilles, this in turn is surrounded by a plastic bezel with a very convincing brushed metallic finish.

The black version is full black contrasted with a glossy speaker frame, matte brushed bezel and a back cover with a matte grained finish which does a very good job of resisting fingerprints. Unfortunately the back's finish feels slightly irritating to the touch and fails to provide maximum grip.

The white version on other hand has a more daring and different finish, it has the speakers' frame coated in red, the brushed bezel painted in silver and smooth glossy white plastic for the back cover. 

The plastic back cover is removable: it's pretty solid but as is typical with such removable covers, it can creak under pressureBeneath the cover cover lie two microSIM slots and a microSD slot as well as a replaceable 1860mAh battery - like everything HTC the interior has surprisingly fine fit and polish.

The camera lens and LED flash are covered by a protective glass bevelled inwards which should prevent it from collecting scratches

The buttons have a nice, solid feel as well. The power button is at top right; volume rocker on the right hand side; and the capacitive buttons are similar to the One, with 'back' on the left, 'home' on the right and the HTC logo in between. The rest is taken care of with gestures. Finally a 3.5mm audio jack is located at top left, and the micro-USB port is on the bottom.

All in all this is a very well built device with a sharp look (especially the black version). The slim tapered edge is reminiscent of the black HTC 8x and compared to competitors' mid-range devices, the Desire 600 build quality and design are miles ahead.


Boomsound versus Boomsound

The Desires 600 sports the HTC One's star feature, dual frontal stereo speakers with built-in amplifiers. This is "only" a mid range phone so you might expect less quality, compared with its big brother: but far from it! Compared to the One flagship it's just a notch lower in loudness and noticeabley less bass. Curiously while the One sounds significantly better with beats audio, the Desire 600 actually sounds better once the default beats enhancements are disabled: leaving it enabled seems to result in a more hollow sound. With this said, the quality is still excellent for its range, beating flagship devices from opposing brands.

If you would like to know more about the HTC One's phenomenal sound quality be sure to check our post: HTC One review - part 2: Hardware

Display, 4.5" Super LCD2 at 245ppi

The screen is another quality seeker on the Desire 600: despite a qHD resolution (960x540), it's running on a 4.5" panel which results in a respectable 245ppi pixel density. The display still inherits all the other Super LCD2 merits from last year's flagship the One X (720p, 312ppi) which  was lauded for its screen quality. Thanks to optical lamination it has excellent view angles and deeper blacks; there is no gap between the glass and LCD itself which makes the screen appear afloat. While not as sharp, colorful or contrasted as the One X, the screen is still significantly better than the Pentile Amoled qHD screen on last year's premium One S.



Camera, 8MP with last year's killer features

Instead of the ultrapixel (a low-light loving sensor with 2.0µm pixel size), the Desire 600 uses a standard wide angle 8MP BSI sensor with 1.4µm pixel size, but keeps the same f2.0 aperture and 28mm unique wide angle lens as the flagship. It also includes the older HTC ImageChip from last year's flagships which gives us powers like HDR, burst shooting and VideoPic (take still shots during video capture) as well as super fast shutter/focus, slow motion video and flash metering: however it loses all the fancy Zoe features, which are enabled by a newer ImageChip 2 on the HTC One. Video recording maxes out at 720p; most likely due to the lesser capabilities of the Snapdragon 200 SOC.

Daylight pictures are of good quality but slightly hurt by HTC's default aggressive digital sharpness: thankfully you can always reduce sharpness using the Image Adjustments menu in the camera app. In terms of low light it's perfectly usable when scaled down, especially indoor shots but 1:1 detail gets seriously degraded due to the smaller pixel size. Unfortunately HDR; which was flawless on last year's HTC One X; fails to do a good daylight job here (curiously it's the same issue as on the HTC One). On the other hand there is a great "HDR low light" feature in Sense 5: when used alongside the LED flash, the camera snaps two shots - one with flash and another without for mixed exposure, it gives far superior results to the washed out colors of standard LED flash photography. 

HTC Sense 5 in duality 

The tested device was preloaded with 1.17.707.3 firmware (Android 4.1.2) & HTC Sense 5.0. This is the same well praised UI from the full fledged HTC One; it is a known quantity by now so let's focus on the advertised features of the Desire 600, BlinkFeed, Video Highlights and dual SIM convenience.

Blinkfeed is HTC's version of Flipboard, it compiles news and posts from various sources (including your social media) in a nice scrolling layout embedded as the main home screen. You can't disable Blinkfeed - but you can set another home screen as your main one, and Blinkfeed will get moved to the right: you can also disable it further by removing newsfeed sources. 

Video Highlights is a feature which automatically compiles a video reel from your photos and videos in your phone's gallery. This works based on an event's time and location (you need to select your gallery content to be sorted by events). You can choose different preset themes for different effects and music. This is all done in real time and it works surprisingly well considering the modest Snapdragon 200 SoC in this phone. If you like the end results you can then save it as an H264 MP4 video to keep or share.

The two Sense 5 features which are missing compared to the HTC One are Sense TV and HTC Zoe, which rely on the One's hardware (IR blaster and ImageChip2).


The way the dual-SIM functionality works is interesting; Sense 5 was revised with this in mind. For example, you can choose Slot 1 or Slot 2 straight from the dialler - and an improvement over the Desire SV is that you can now receive notifications about two calls at the same time... you can even answer both calls and the first one will be placed on Hold. Throughout the UI there are other optimisations to help you use both numbers without mix-ups.

One thing to keep in mind about a device in this range: while it will surely receive maintenance updates from HTC, unlike the high end phones don't expect a long term commitment regarding Android (or maybe even Sense) updates.

In terms of connectivity, only one of the two microSIM slots supports 3G/3.5G (HSPA) - the other only supports 2G/2.5G (Edge). The Desire 600 also includes GPS/GLONASS, NFC and Bluetooth 4.0 with APTX support.

Performance, a slow quad core 

Here we arrive at my main niggle with this device: while it is mid-range it's still not an entry level device - and priced at around 400$ we should expect a decent performer. Unfortunately this 1.2ghz Snapdragon 200 SoC variety includes quad A5 cores and an Adreno 203 GPU along with a 1GB of DDR2 RAM. The quad will certainly assist in multitasking preventing long waits or hangs (which means it does well in certain benchmarks) but in terms of raw processing power the A5 is merely adequate and the entry level GPU is overstretched by the qHD resolution. This is why the Desire 600's UI is nowhere near as snappy or smooth as the HTC One Mini. You'll find that you can improve the smoothness of the UI by enabling "Force GPU" and "Disable HW overlays" from the hidden developers options. 

For those interested here are some benchmarks and system details:




Gaming, an entry level GPU

Given the affordable price, excellent stereo speakers with built-in amplifiers and a good quality screen, you can enjoy casual gaming on this device and lighter games. Temple Run 2 ran extremely smoothly in medium graphics mode (laggy if raised to high): but heavier 3D games like Fast & Furious 6 had most graphics intact, yet with a very poor frame rate. Ripetide GP2 ran with most fancy graphics enabled but at a poor (unplayable) frame rate: however reducing the game resolution or graphics effects from the in-game settings did improve things. 

In order to assess the GPU let's check the following GFXBench comparative, this is run onscreen since it reflects actual 3D gaming at the device's native screen resolution:

HTC One, T-Rex HD 15fps, Egypt HD 40fps (onscreen FHD - Adreno 320)
HTC One S, T-Rex HD 11.3fps, Egypt HD 28.4fps (onscreen qHD - Adreno 225)
HTC One Mini, T-Rex HD 9.3fps, Egypt HD 24.2fps (onscreen HD - Adreno 305)
HTC Sensation XE, T-Rex HD 5.9fps, Egypt HD 16.3fps (onscreen qHD - Adreno 220)
HTC One X, T-Rex HD 5.5fps, Egypt HD 15fps (onscreen HD - Tegra 3)
HTC Desire 500, T-Rex HD 4.7fps, Egypt HD 11.9fps (onscreen WVGA - Adreno 203)
HTC Desire 600, T-Rex HD 4.0fps, Egypt HD 10fps (onscreen qHD - Adreno 203)
HTC Sensation XL, T-Rex HD 3.1fps, Egypt HD fail (onscreen WVGA - Adreno 205)
HTC Explorer, T-Rex HD 0.9fps, Egypt HD 3.5fps (onscreen HVGA - Adreno 200)

You can clearly see the Desire 600 is around the bottom of the list: its modest GPU is over stretched by the qHD resolution. Adreno 203 seems to have been updated over the old Adreno 205, it fares better on the WVGA Desire 500, but it's nowhere near as fast as the Adreno 305 on the HTC One Mini or Galaxy S4 Mini/Duos - and the HTC One's graphics power seems like a distant dream.

Battery life

The included 1860mAh battery sounds good on paper but in practice with dual SIMs and data connections fully engaged you will be lucky if it lasts you the full day. Of course your mileage will vary but connectivity is the biggest drainer here - use with care.

Conclusion

The most impressive aspects of the HTC Desire 600 are design; build quality; sound and screen quality. There is no doubt HTC can design and build phones better than most - even if mid-range, even if plastic. Couple that with an impressive list of features thanks to HTC Sense 5, plus some unique hardware, and you have a really nice, slimmed down, affordable HTC One experience with an added dual SIM functionality: a "reason to buy" for many.

I can not but wish it had the Snapdragon 400 with dual Krait cores and Adreno 305 instead of the average SoC it's carrying, quad core or otherwise, it would have been a killer mid-ranger. Surely this must be the reason why HTC just announced the Desire 601 with Snapdragon 400 (and there are rumors of a dual sim variety).

Alternatively if you are around this budget and dual sims are not required, you can simply buy last year's flagship the HTC One X (or One X+) and update it to Sense 5: you would have an acclaimed smartphone with a vastly superior speed, screen and camera.

Hardware Summary:

+ Excellent build quality and design for the price
+ Excellent stereo speakers with built-in amplifiers
+ Good quality screen with excellent view angles
+ Dual SIM convenience with good UI integration
+ Impressive automatically generated Video Highlights in the gallery
+ Speedy camera thanks to HTC ImageChip

- Low End Snapdragon 200 SOC despite a quad core CPU
- Struggling Adreno 203 GPU for qHD resolution, limited gaming
- Slippery back cover

Pixels and Pixellation

How many pixels do you need? This is a question many, many people ask and to be honest I think it's the wrong one. Let me give you a few numbers!

First of all, it's widely accepted that a monitor with more than 100 "dots per inch" or "pixels per inch" placed 18-24 inches from your face looks pretty good - with outstanding monitors at that distance having 130-170ppi. I'm also going to assume that the average monitor resolution is 1080p - that's 1920x1080 pixels in a 16:9 rectangle. This is actually quite generous but I've done that deliberately. Now when you're printing images on paper, it's generally accepted that 200ppi is "reasonably good" quality, and 300ppi is "excellent".


Full image - 2688x1520 (4 million pixels) displayed at 600 x 339
So - with a 4 million pixel image in a 16:9 arrangement, your image dimensions are going to be close to 2688x1520. If we divide that by 300ppi for printing we get a print size of 8.96" x 5.07". Call it 9" x 5" for round numbers and you're looking at an "Excellent" quality image bigger than most commercially bought prints which would be 6" x 4" or 7" x 5". Start blowing up from 9" x 5" and you're slowly going to start losing image quality. Pixellation will likely begin to occur at about 13" across. For displaying on a screen it's a completely different story: 1920 x 1080 pixels is about 2 million pixels altogether; and at the very best quality I've ever seen for myself (130ppi) that's a monitor size of 14.76" x 8.31" (about a 17" 16:9 monitor). So - if you display a 4 million pixel image on this monitor you're zoomed out so that half of the pixels in the image are never displayed. If you zoom in so that every pixel is displayed you can only see half of the image's area: but still at 130ppi you can't see individual pixels and the image quality is absolutely perfect. On my monitor at work, which is 22" 1680 x 1050 (90ppi) I begin to be able to resolve individual pixels with the naked eye when zoomed in to around 350% - where each image pixel is represented by 3.5 screen pixels on average.

So - let's use these as our ballpark figures; zoom in to 350% or print larger than 13" for individual pixels to appear on a 4 million pixel image.


The original image, cropped to 600 x 339 pixels and displayed at full size. Note the complete lack of pixellation - although there is a certain fuzziness to the detail.
Now, let's look at how the vast majority of mobile phone users use the photos they take. Please don't think of yourself or your friends here; think of the millions of people buying smartphones and how THEY use their pics. Look at Facebook, Flickr, Tumblr, Twitter, etc. That's right - MOST people - the vast majority - use the photos the way they come out. They don't edit, they don't crop, they don't zoom, they don't do any more than perhaps a bit of red-eye removal. And how are those images distributed in the main? They are very rarely displayed at their full size (in fact Facebook almost never even holds the pictures at full size but "processes" them in a way which removes massive amounts of detail and image quality to save storage space). Most places (Facebook included) allow you to choose a range of sizes to upload at, to optimise data traffic and storage space use.

The original image, cropped down to 198 x 146 pixels, and displayed at 600 x 339 to keep the playing field level with the other images. Note the fuzziness; and you can start to see individual pixels. This is now less than 9% of the original image, AND it's blown up to four times actual size.
So - the image you see on the screen is usually displayed to you at 600-1000 pixels across - far less than the original photo. At this resolution, a photo taken at 13 million pixels and a photo taken at 2 million pixels will look EXACTLY THE SAME. There is simply no way to see the original detail because making the picture that size has destroyed it - and if both are now the same width with the same scene depicted the remaining detail in the picture is also the same.

Now - there are a minority of smartphone camera users who shout "but I crop, zoom, edit my images - 4 million pixels is not enough!". I don't want to make fun of those people but - if you take a photograph so poorly that the image you want from the original picture is 30% or less of what you photographed, you're doing it wrongly. Take the photograph you want in the first place rather than taking a wider scene and then cropping it down to a postage stamp. Move closer to the subject and frame it properly. If you can't move close enough that the subject is easily visible in the frame, then a smartphone camera is the wrong tool for that image. Use a camera with a nice big lens, optical zoom and a nice big sensor. Smartphone cameras were (and are) intended for quick opportunist snaps; although a skilled photographer can capture some outstanding images with even a 4 million pixel smartphone camera because they're a skilled photographer. For examples of what I mean, look up Colby Brown who uses smartphone cameras to take many of his unbeatable images. All are displayed on his site at 1140 pixels across and yet they look absolutely fantastic regardless of the camera he used. Another up-and-coming digital photographer is Craig Fish who also uses a 4MP smartphone camera for many of his shots.

To prove my point, here are links to one image which has been progressively halved in size until the smallest one is HALF A MILLION PIXELS. I challenge you to see the loss of quality without zooming in... until you get below the resolution of your monitor.


Original image: 4 million pixels
Half Size – 2 million pixels
Quarter size: 1 million pixels
One eighth size: half a million pixels

Cameras in Phones - what do we really need?


An awful lot is being said about mobile phone cameras just lately; and we have HTC to thank for opening the conversation with the introduction of their HTC One which has half as many pixels at twice the size of anyone else's. Before we begin I'm going to get some ground rules. I won't use marketing terms; so I will talk about how many pixels a camera sensor has, and what size they are. You won't hear me talking about mega- or ultra- anything. Next is that I will show my meaning with diagrams - I'm a visual person and it helps me to explain. Please bear with me on this post; there's a lot to read but it's worth it at the end.

A digital camera uses a lens to focus an image onto an oblong of special material which has a number of sensors on it; each sensor is called a pixel and usually contains three sub-pixels; a red, a blue (actually two blues but don't worry about that) and a green one. Each of these sends a signal to the camera depending how much light of that colour is falling onto it. Bigger pixels produce a bigger signal for the same amount of light than smaller ones. When signals are small, the amount of noise (erroneous signal levels produced simply by electrons moving around) is a bigger percentage of the whole signal because noise is a constant backdrop. When the signals are bigger therefore, it's easier to pick out the signal, from the noise. More noise means that the signal produced by a smaller pixel is less accurate which means the final photo may not have exactly the same colour from each pixel receiving the same light.

Camera sensors line up their pixels in rows and columns - and the camera's rating is often quoted by counting them. For instance a 10MP camera contains ten million pixels (roughly). These are arranged in a rectangular grid with a side length ratio of 16:9 - so that's 4213 pixels across and 2370 pixels high. If you have a sensor which is 7mm across, each pixel is 7/4213=1.662 microns across (microns = thousandths of a millimetre).

In the real world, standard sensor sizes and pixel sizes exist; a 13 million pixel camera in a phone will have pixels about 1.1 microns across; this gives a sensor width of about 4.55mm (there are 4128 pixels across the image). In the HTC One, the best photos are 2688 pixels across, and the pixels are 2 microns across giving a sensor width of about 5.4mm.
Figure 1 - 4 million large pixels
Figure 1 - 4 million large pixels

Figure 2 - 8 million (smaller) pixels on same size sensor
Figure 2 - 8 million (smaller) pixels on same size sensor
Now we can start looking at construction. Take a look at Figure 1. This shows a camera with large pixels - the lens is focussing the image onto an area exactly the same size as the sensor. In Figure 2, we gave the camera more pixels (which really does give more detail in the image but at the expense of noise and grain - and also less sensitivity at low light levels). Of course; straight away you want more, BIGGER pixels. Figure 3 shows that if you make that happen, the image doesn't cover the whole sensor; the light falls on a little bit of it. So - in Figure 4 we move the sensor further away to ensure the image covers all the pixels.
Figure 3 - 8 million large pixels with no other changes

Figure 4 - Sensor moved away, but the lens size is unchanged.
Figure 4 - Sensor moved away, but the lens size is unchanged.
However; the same amount of light, entering the lens, is now spread over a wider area: this dims the light hitting each individual pixel, which reduces the signal output and increases the noise. The only way to change this is to make the lens bigger - the aperture wider - so that more light gets in. This is shown finally in Figure 5.
Figure 5 - all required changes incorporated.
Figure 5 - all required changes incorporated.
So - how far back do we have to move the lens? Simple trig shows us the answer. Imagine the "field of view" of the lens is about 60° (not unreasonable): the light coming in from the left and right cross over in the centre of the lens and make a triangle with the sensor as the base... an equilateral triangle is formed with all angles at 60° and all sides the same length (let's call it 5.4mm to stick with the HTC One's sensor size). So the lens must be 2.7mm away from the sensor. If we now make the sensor an 8MP one (3800x2140 pixels) that gives a width of 7.6mm - the lens still has a viewing angle of 60° so that means the sensor has to be 3.8mm away from the lens. Obviously I have used 60° as the lens viewing angle because it makes the angles, sines and side lengths easy to calculate - the numbers are probably quite different in real life but you get the idea: to get double the megapixels you have to move the sensor further from the lens, which means you need a bigger lens to gather the light needed to adequately illuminate it. Lenses very rapidly increase in price with size - a lens 4mm across instead of 2mm might cost three or four times as much. (BTW - the large circular opening on the back of the phone is NOT the lens; the lens is the tiny dark speck in the centre of it).

In practical terms for a smartphone? This means that, to get an 8 million pixel camera, with pixels 2 microns across, your phone would need to be about 16-18mm thick (at least at the camera's location); and the phone would cost upwards of US$1000 - possibly even more - JUST because of the lens.

This isn't something which can be corrected with better design, or better lenses; the only way to mitigate this increase in size and cost would be to make smaller pixels which had the properties of larger ones - and that my friends is the nirvana of a pixel scientist! The very best technology available is going into these phones - and with today's tech we're stuck with these limitations. In another article I'll talk about why I believe 4MP at 2 microns across is enough.
