BlackBerry Q10 review: Qwerty is back

• 
  

• Look and feel
• Display

• Operating system and performance
• Camera and multimedia
• Battery life and conclusion

PROS

• Performance
• Display quality
• Features
• Battery

CONS

• Odd aspect ratio
• Too few applications

Canadian smartphone maker BlackBerry has tried to bring back the glory of Qwerty keypads with BlackBerry Q10. The smartphone is based on BlackBerry's latest BlackBerry 10 operating system, which comes with a lot of features.

The BlackBerry Q10 has a premium appeal at a premium price point of Rs 44,990. But is it really worth the price? Let's find out.

Look and feel

The BlackBerry Q10, as the company describes, is a premium product and has been priced likewise. The device is very well designed.

The Q10 has a machined metal chassis carved out of a single piece of metal for durability; while special care has been taken in the selection of metal to make the device light as well. We received the white variant that misses out on the signature glass weave back panel, but the high-grade polycarbonate felt quite sturdy.

On the right side, the BlackBerry Q10 has volume controllers while on the top it has the power button - both metallic. The loudspeaker has been placed right at the bottom of the device while the 3.5 mm audio connector has been placed on top for easier access. Overall, the device is lightweight while its textured back has a good grip.

The keyboard, which is the highlight of BlackBerry Q10, has an excellent tactile feel. The keys are also big enough for easier typing. The key rows are straight with a silver strip above each row that gives the phone a classy look.

Display

The BlackBerry Q10 comes with a 3.1 inch Super Amoled 720 x 720 pixel display with a density of 328 pixels per inch. The display is good for most tasks including watching HD videos. But even though everything is good, the odd aspect ratio might not be liked much. While playing videos, the display simply wastes a lot of real estate and videos that are already tiny look even tinier. The moment a video is played the top and bottom of the screen show these big black bands that happen due to wide screen videos being resized on a square screen.

The touchscreen on the other hand is quite responsive and actions are translated on the device without any effort or lag. The Q10 offers very high pixel density, which makes visuals lively and there is no pixilation anywhere, anytime. Sunlight legibility is also good due to higher contrast and brightness, plus the ambient light sensor works flawlessly offering great visuals all the time.

Hardware

The BlackBerry Q10 comes packed with a dual core 1.4 GHz OMAP 4470 processor from Texas Instruments based on ARM cortex architecture and 2 GB of RAM. The hardware configuration, along with with the new age operating system, offers fluid operation and reduced application load time. The lack of a home screen and the adoption of swipe gestures for the user interface take some time to get used to but actually offer better performance and utility than having buttons on screen.

The BlackBerry Q10 comes with 16 GB on-board storage and an expandable slot for up to 64 GB micro SD. The Q10 also features an HDMI input for connecting the device to a large HDTV directly.

For wire-free connectivity the Q10 comes with Bluetooth 4.0 and NFC, which though it has been slow in terms of adoption, is a good feature to have for future.

Operating system and performance

The relatively new BlackBerry 10.1 OS makes the BlackBerry Q10 look good and perform well. Those who are worried about the big difference in the new OS 10 will hardly take a day to get used to the BlackBerry 10 OS.

In the BlackBerry Q10, the company has added a new Type and Go function. If users want to send an email to someone in the phonebook they just need to type 'email,' followed by the Contact's name and the device gives the option instantly.

A similar shortcut can be tried for the BlackBerry Messenger, Facebook or Twitter apps. Just type the app's name and contact name to send the message to the user. You need to press through the different navigation levels for sending an email. Another visible change is that the Active Frames appear square instead of rectangular because of the smaller display.

The swipe functionality for the operating system and user interface works great but the space between the touchscreen and physical keypad has been kept too less. While using the device we ended up touching and pressing the upper-most row multiple times while all we needed was a clean upwards swipe.

Another highlight of the phone is the predictive input system, which was adopted for the BlackBerry Z10 and has been disabled by default for the Q10. Although having a physical keypad makes no sense having predictive input would save more time and as far as utility goes the touchscreen is anyway close enough for users to select words from the suggestions given on the screen.

The much talked about application store doesn't feature many utility based applications for the Q10 specifically and the same old applications that were available for OS 7 based devices still exist as the top most preference.

Overall, the BlackBerry Q10 is a good device provided that applications are made available to unlock its full potential. The Q10 utilises optimisations done on the OS for better and more fluid performance. So it does not matter if it's a dual core processor it justifies smooth and effective device usage as well.

Camera and multimedia

BlackBerry has used an 8 megapixel camera with auto focus and LED flash at the back. The camera is quite responsive and is the same unit as the one used on the BlackBerry Z10.

There is a 2 megapixel front facing camera for video chat and video calls via BBM but the camera interface does allow users to capture self-portraits with that or use it as per their need. The BlackBerry Q10 can record 1080p videos using the rear camera and 720p videos using the front camera. The image quality is good but it lacks sharpness, plus the square screen is really not meant for viewing pictures and video, which adds to the pain.

Yet, the camera justifies its presence with decent all round picture in good light conditions, while low light images are supplemented with LED flash. Video playback as we mentioned earlier is a nuisance and is better avoided on the BlackBerry Q10. Music playback on the other hand is good and the loudspeaker is one of the loudest in smartphones today. FM radio is still missing but hopefully upcoming BlackBerry models like the Q5 will come with it, as rumors have suggested.

Battery life and conclusion

One of the best features of the BlackBerry Q10 is its battery management system that ensures that the device does not run out of juice in the middle of the day. For average users the device would last anywhere from 1.5 to 2 days and for heavy users it would still manage to give about 1-1.5 days worth of backup.

But ultimately the BlackBerry Q10 is something BlackBerry fans were really waiting for though the price might turn off some of its fans. The device, without any doubt, has a premium appeal to it and offers NFC and HDMI along with core BlackBerry functionalities.

So, leaving price aside BlackBerry Q10 is a premium device with premium appeal and pricing as well, but to justify that BlackBerry Q10 offers a great Qwerty keypad, good but strange square-ish display, amazing battery life and features to keep you going for the next couple of years. The only snag is that it has very few applications.

SK Telecom launches the world's first LTE-Advanced network, and the Galaxy S4 LTE-A

Just days after an LTE-Advanced variant of Samsung's Galaxy S 4 leaked, Korean carrier SK Telecom has officially announced it's launching the world's first publicly available LTE-Advanced wireless network. The Galaxy S4 LTE-A is also official (in red or blue) as the first device able to take advantage of the new technology for even faster data transmission speeds. According to the press release, SK Telecom plans to have as many as seven LTE-A devices available by the end of the year, all capable of up to 150Mbps. While SK Telecom is using Carrier Aggregation and Coordinated Multi Point technology to improve speeds right now, it will add Enhanced Inter-Cell Interference Coordination in 2014 to go even faster. After that, it suggest carrier aggregation will improve to support higher speeds and faster uploads in subsequent years.

To take advantage of the higher speeds, SK Telecom's Btv IPTV service will begin offering 1080p video streaming in early July. That will be accompanied by enhanced multiview baseball broadcasts, more free videos, an HD video shopping service with six channels on one screen in August and the addition of FLAC audio files via its music package. Right now, the company has Seoul covered in LTE-A, and plans to eventually offer it in 84 cities, all at the same price as existing LTE service. Check after the break for the press release with all the details, plus video of a speed test.

Update: We've just come across another juicy tidbit that makes the Galaxy S4 LTE-A all the more worthwhile -- it'll ship with a Snapdragon 800 SoC that contains a 2.3GHz quad-core CPU, plus 32GB of built-in storage and a 2,600mAh battery. It goes without saying that this phone will be speedy on all angles. As spotted bySlashGear, the new GS4 variant will also see the debut of a new Samsung software feature: ImageON. Explained as a Google Googles-esque app, it'll automatically analyse photos and offer up related videos and "extend access to relevant content on the internet."

Jun Katsunuma on the inspiration for Xperia Z Ultra's design

Sony's Jun Katsunuma on the inspiration for Xperia Z Ultra's design

After the Xperia Z Ultra's launch event in both London and Shanghai, we had a brief chance to talk to Sony's Product Design Director, Jun Katsunuma, who was present in the latter city. Jun's been responsible for Sony's mobile devices since the Xperia S days, so the transition to the Xperia Z's double-glass design was also under his watch. That said, the newer Xperia Z Ultra isn't simply just an enlarged version of its smaller sibling, as we found out straight from the horse's mouth.

"The frame [on the Xperia Z] is made of plastic, then we picked a PMMA (a transparent thermoplastic) for the plate," Jun reminded us while holding both devices. "But this time we use aluminum in the side plates, which means it's totally different, then we could realize this super thinness [on the Xperia Z Ultra]."

On a similar note, Jun pointed out that the Xperia Tablet Z is more like the Xperia Z, except for the former's reinforced fiber back. Even then, the tablet is thicker than the Xperia Z Ultra by 0.4mm, courtesy of the latter's aluminum contruction.

Here's another subtle difference that Jun shared with us. While the 6.5mm-thick Xperia Z Ultra has the same black, white and purple options as the thicker Xperia Z, the designer intentionally chose not to give the new phone the same glittery purple paint. The reason being a solid purple apparently just looks better under the larger piece of glass. And it's not Gorilla Glass here, by the way, but Jun and his colleagues assured us that the glass on the new phone is just as strong -- especially since the super responsive touchscreen (our guess is that this is Atmel's solution) supports pen and pencil input.

Without naming the elephant in the room, Sony Mobile's Marketing Programme Manager Benoit Obadia acknowledged that there's indeed a stronger request for bigger displays on phones these days. But as to why his team specifically chose a 6.4-inch screen size, Jun said it was simply a matter of finding the largest panel that he could fit into the width plus a similar thickness of a passport -- something that travelers are used to carrying around all the time, especially in their coat pocket. Similarly, seasoned travelers are also likely to be carrying a pen, which can be used for scribbling on the Xperia Z Ultra. That way they won't have to carry a dedicated stylus.

"The point of this Xperia Z Ultra is how we could let the users bring this one into their travel and daily life," said Jun. "That's why we chose aluminium to realize our product's proposition."

Lastly, we pointed out the potential fatigue over the all-too-familiar design ID of the latest Xperia-branded devices, but Jun and Obadia implied that at the moment they're not too concerned due to the positive response. Still, the designer realizes there needs to be a balance, and his team solves this problem by implementing some subtle but practical differentiation.

"At Sony, we need to bring some of that message with consistency," said Jun. "The Xperia Z, the Xperia Tablet Z and the Xperia Z Ultra are very strong in consistency, but of course, they have different propositions. So that's how we decide to use some different materials, different pigmentation and sometimes construction. Based on this product and based on our one design language, we really do some differentiation but with high consistency.

"The use case of the smartphone is changing, so we need to consider how we can express the differentiation in any use case in any product. So we create our designs based on this high-level concept."

[GUIDE] Root for Verizon Galaxy S4

Description: This is a simple guide that will allow you to easily root your Verizon Galaxy S4 device without having to wipe your device or flash a full prerooted factory image. This method works using a leaked prerelease kernel (provided by user sextape) and root method (provided by user djrbliss). Only change is I have modified the Motochopper root method to use the latest SuperSU instead.

Android Reverse Tethering for windows users.

Android Reverse Tethering for windows users.

Tethering is the ability to surf on your pc using the 3g of your phone
Reverse tethering is the opposite : surf on your phone using the ADSL of your PC. No Wifi or 3G connection required.

This work only for rooted users !!!For non rooted users, you can try my other solution, but require more manipulations and is limited to surf : http://www.codeproject.com/KB/androi...orwarding.aspx

Installation :
Unpack the zip file. This zip files contains the windows part, ADB and the android APK.

Before starting the tool : 

• You must install drivers for your device. Generic driver provided by google is on the usb_driver.zip
  You can also check the Universal Naked Driver
• Ensure you have debugging enabled on your phone :
  Settings > Applications > Development > USB Debugging > Turn On
• Ensure you have root access AND SuperUser application installed.
  Change the superuser settings (Menu -> Preferences -> Notifications part) :
  Uncheck "Notifications" label to display "Do not show notification when an app is granted Su Permissions"

AndroidTool
The AndroidTool.exe is the windows part

The low level communication tool (ADB) is included in the zip file.
AndroidTool will try to find ADB in c:\android-sdk-windows\platform-tools\adb.exe
If not found he will use the provided one.

The first time you use the program :

• If you want to use another version of ADB, clik "config" and in the first tab enter the path to the ADB
• Select the DNS server to use in the right list. On complex system, some dns can be detected.

Start reverse tetheringJust click “Connect”.
If it's the first time you use the program, This will install the latest android package and the dependencies (busybox and redsocks).
The SuperUser process may ask you to allow “Usb tunnel”



If the android process crash after receiving superuser rights, close the windows program and start again.

The android interface (first tab) will show connections forwarded to windows.
Others tabs are just for debugging (give information about system route tables and connections). Not yet finished.

Start your browser 
Google chrome will complain that no connection is available. Don’t care. That work.
Firefox , opera and dolphin don’t have problem with that !!!

The current version of the application can’t forward low level ICMP packet (PING).
From Android Os point of vue, there is no internet connection.

Google Market/Play :

For android 4.x ONLY
Since reverse tethering version 3.4, it's now possible to download/update application.
This step is optional !
Required only if you want to download from market.
I recommend you to perform a nandroid backup before installing the hack.
Don't worry, I didn't brick my phone and tablet during the development.
The Xposed framework author and me are not responsible for anything you do with your phone/tablet/rice cooker.

• On the windows program, go to tools tab and click "install hack"
• Launch the Xposed Installer (you just installed) on your android and click on "Install/Update"
• Go to the module tab and check the HackConnectivityService (see screenshot below)
• Reboot the phone
• Done!
  This work for market but also for some other programs (some games,skype,hangouts...)
  
  

For older android 2.x or 3.x version :
The application want to have an active 3G or Wifi network interface.
Some market applications are tagged "Wifi" only.
To get around this problem, you can activate the 3G BEFORE starting reverse tethering,all the data will goes to the usb.
Tips : You can connect to some wifi hotspot not protected by a key.
It's only when you want to surf that the hotspot ask you a user/password.
But, at this point, we have an 'active' connection. Market download should work after starting reverse tethering.

Not fully working application but work if you install the HackConnectivityService on android 4.x:

• Market download
• Spotify
• Skype. (not checked yet)
• If someone know another one, post a reply !

Troubleshooting

If your device is not listed in the "select a device" combobox :

• Ensure Usb debugging is enabled (Settings > Applications > Development > USB Debugging > Turn On). Deactivating and reactivating the Debug mode may help
• The ADB subsystem is sometimes not working properly. Click the "Kill ADB" button (on Tools)
• Your device is perhaps not installed properly. See your device manufacturer. You can download a generic driver from google here :http://developer.android.com/sdk/win-usb.html.
• Windows can detect your device as a "Media Transfer Protocol" (MTP) or "Picture Transfer Protocol" (PTP). When you connect the usb cable, you have a notification. Click the notification to change this parameter. If one don't work, take the another one...

Click refresh or restart the tool to detect your device.
If the connection shutdown often, try another usb cable

Android 4.3 Troubleshooting
Google added some security stuff on this version.
Important : You have to connect your phone/tablet to wifi at least once after boot before using reverse tethering !!!

Proxy :
There is 2 problems with proxies :

Android 3G proxy. Even if 3g is desactivated, your provider (APN) proxy may still used by applications.
The windows tool is not able to communicate with your provider proxy.
Note that not all providers include a proxy. You must remove it manually.
The tool will give you informations on how to do it when detected.

Corporte proxy. The windows application is not able to traverse proxies.
The good news is that you can use some applications like FreeCap , sockscap and proxifier.
You must start the androidTool from one of these launchers, giving proxy adress and port.
Thanks "edgd1er" for the information.

History :

Version 3.14

• Small bug fixes, added debug code in case of crash
• Added xposed debug code for connectivity hack

Version 3.11

• Nothing in the program
• The zip include the latest Xposed framework.
  It's NOT mandatory to update to the latest framework.
  Usefulll only for android 4.3.

Panasonic P51 review: A BIT OF disappointment

PROS

• Build quality
• Camera
• Battery life

CONS

• Price
• Low internal memory

If a handset player doesn't have a phone for the Indian market, it is not on the right track. This is not a personal statement. Rather, it is a reflection of what is happening in the country. Except for a few players that you can count on your fingers, almost all the major players from across the globe have launched their phones in India.

The latest to join the party is Panasonic, with the Panasonic P51, and that's not all, it has even tied up with the Jaina Group (parent company of Karbonn mobiles) for leveraging their distribution network for making P51 available across India.

We have been reviewing Panasonic P 51 for the last 14 days and here is our take on the company's first smartphone for Indian consumers.

Inside the box

In the box of Panasonic P 51 you will found a magnetic flip cover, stylus, charger and data cable. We didn't find use for the stylus as the device was quite responsive to touch.

Also, instead of a magnetic flip cover a full smart cover would have been quite handy.

Look and feel

If you don't take a close look at Panasonic P51 or hold it in your hand, you might mistake it for LG Nexus 4 for they look remarkably similar.

But, you will feel the difference after holding it in your hand. The back panel of the smartphone is slightly protruding, which gives Panasonic P51 a unique design. Its full glass front panel is surrounded by a raised grey coloured graphite strip (in the white model,) which protects the screen from scratches when it is face down.

The Panasonic P51 has a unibody design, thus one cannot replace the battery. We received the white coloured unit for review. It has a glossy plastic body but isn't a fingerprint magnet. It doesn't feel cheap but I would prefer the black coloured device with a rubberised back panel.

The 5 inch screen of the Panasonic P51 is made of Asahi Dragon Trail glass. It is claimed to be better than Gorilla glass in terms of scratch resistance.

The front panel of the smartphone doesn't have any capacitive buttons-return, home or menu; rather, they are embedded in the display itself and thus can be accessed when you turn on the device. The top of the front panel has a steel mesh grill and front camera, and a couple of sensors.

In the top panel you will find a power button along with a 3.5 mm jack. On the right side of the phone there is a volume rocker and right below it a micro SD card slot, which is covered by a plastic door. The left panel of the smartphone houses two micro SIM card slots covered with a single plastic door, and a micro USB port.

The overall body of P51 looks solid. The design is attractive but the button and port placement could have been better. The power button is not easily accessible; the volume rocker and micro USB ports are awkwardly placed. After using the phone for some time you will get used to the button and port placements, but you will wonder why Panasonic made such silly flaws in the design.

Nonetheless, the above mentioned flaws cannot take away the goodness of the overall design of the smartphone and the good quality plastic used in making it, as compared to Samsung's Galaxy smartphones.

Display

Panasonic P51 has a 5 inch IPS display with 1280 × 720 pixel resolution made of Dragon Trail glass.

The pixel density of the display is 294 ppi and as compared to other devices with 1280 × 720 pixel resolution, it has better colour reproduction and outdoor visibility.

Viewing pictures or videos on Panasonic P51 is a pleasure. Surfing the web or checking out mails is not stressful on the eyes either. I was not comfortable using the magnetic flip cover so during the review I used the smartphone without any protective covering. Despite my rough usage there were no scratch marks on the display.

Camera

Panasonic P51 has an auto focus 8 megapixel rear facing camera and a 1.3 megapixel front facing camera.

Rear camera

Snaps taken with the rear camera gave good results in well-lit conditions and in low light they were of average quality. Especially portraits and close ups come out really well. Also, auto focus does a good job.

Panasonic has not overlaid a unique user interface over the camera app and it comes in standard modes like panorama, smile detect and HDR, but not multi-angle, which is a sweeping panorama made of multiple angles of a picture stitched into a single snap.

The rear camera of P51 can also record full HD (1080p) videos. To avoid shakes while recording it has incorporated software based image stabilisation. Video quality along with audio is quite good in well-lit conditions though in low light it is found wanting.

Front camera

The 1.3 megapixel camera is okay for self-portraits as well as for video chatting.

Hardware and performance

Panasonic P51 runs on Android 4.2 Jelly Bean and is powered by a 1.2 GHz Mediatek MT6589 quad core chip, which is used in Micromax Canvas HD and many other low cost quad core phones. Panasonic though has not tinkered with the stock Android user interface, which is quite popular.

Like most mid-range smartphones from Indian players, P51 too has 1 GB of RAM and 4 GB internal storage. Internal memory can be expanded up to 32 GB using a micro SD card.

I would have loved it if the device had had additional internal memory or a bundled micro SD card because the current 2 GB seems too low for a Rs 22,000+ phone. One may feel frustrated because lack of space may prompt messages asking to free up some space to continue downloading.

If we look at other smartphones priced at around Rs 24,000 like Samsung Galaxy SIII, we find internal memory and processor speed to be inferior in the P51.

Surfing, using cellular data connectivity and syncing the smartphone are very smooth and fast. If you love playing Fruit Ninja, Subway Surfer or Temple Run you will be satisfied with the performance, but when you use the device for playing high end graphic intensive games like Real Racing 3 or Mortal Combat you will encounter some lag.

Battery life

The Panasonic P51 is powered by a huge 2500 mAh battery. To our surprise, we got one and a half days ( 1day, 16 hours) of power backup on a single recharge.

In the said period I used the phone keeping 3G, WiFi and Bluetooth on. Apart from that, mail and contact syncs were also active. I used the phone to browse the web for around 45 minutes, played games for about 30 minutes, made calls for around 1 hour and listened to music for about 40 minutes.

In short I can say if you're looking for an Android smartphone with good battery backup Panasonic P51 is a device you could check out.

Conclusion

Is Panasonic P51 worth buying for Rs 22,500? In terms of design, performance, camera and battery it is worth buying, but memory and processor speed are not up to the mark as compared to its competitors (Samsung Galaxy S III, LG Optimus Vu). In fact, handsets with the same specifications (Micromax Canvas HD, Gionee GPad and Xolo Q1000) are priced far lower than P51.

Also, if in the coming days there is a price reduction of, say, Rs 4,000 then this phone is a good buy.
