Moblie Phones: "The Inside Job"

At this festival season, new grand mobile exchange is available!!!

All kind of mobile available here, ICS 4.0 upgrade also available here!!!

Take maximum value of your old phone & buy new android!!!


What you read at mobile shops? 4.0" display, ICS, 1GHz processor (quite cool), blah blah blah............

Just go into mall and pick up new phone (just like ticking). HTC, Samsung, LG, Sony & new generation Micromax...........What would you buy?


I am writing this because i am facing this problem since 1 month (dated 26-sep, 2012). In India, Specially in Ahmedabad. No shopper has knowledge of mobile's actual configuration. (I can speak in front of them & i did it, too). Which one is good or better i can't throw this question on salesman.( i am salesman, too but not of mobile phones)




So, what can we do. Just go to gsmarena or flipkart or wikipedia(!!!) and compare these phones to each other. Ask yourself it is really useful for you? (except prices) Any technical information is useful to buy new phone? You pick a model of samsung & ask about the market (to your friend), annd of course they say "ya it's good but few more thousands & you can also buy this phone which has really good functionality" & we became confused (some people calls it is stress)


So, finally i do all this things, & know the whole concept about selling product to a "confused customer".

May be this article became useful to you. Caution: Valid upto new models are not launched.


1. First thing first : Money

                                       Actually it comes last.

2. Processor





Ya, if you use nokia "n series" or samsung "bada os" phone. you are using ARM processor which is production of arm corp. The higher version of this arm processors are called "Cortex". Most of new android phone has this Cortex processor. which also have different versions. A5, A7, A8, A9, .............

This is same processors which used in Apple devices. Iphone 2, 3, 3S, 4, 4S, 5..................All the models have these arm processors. and of course 


A5 < A7 < A8 < A9


OK, So phone has A9 processor it's better then all others. Now one other thing it's single core or dual core? Well, of course dual core is better. Now 1Ghz is better then 800 Mhz. & 1Ghz dual core Qualcomm is better then 1 GHz. So, eq. is 


600 MHz < 800 MHz < 1 GHz < 1 GHz dual core < 1.x GHz (/dual core)


this is basic need processors. which we seen in market with mid-range phones. & ya of course if you want to use ICS 4.0 (Ice-Cream Sandwich 4.0 Android) phone must be 1 GHz, A7 processor or higher.

Game is not end here,  This is just a processor. It can't work without instruction set & other peripherals just like motherboard in PC. Which is developed by "Qualcomm". Qualcomm has architecture named "Snapdragon" it also has version v1, v2, v3, v4........................


Sanpdragon v1 < v2 < v3 < v4  


Which phone has best processor & architecture : 

Iphone 4S - Sanpdragon v4, Cortex A9, 1.x GHz dual core                          around 40,000/-

Samsung Galaxy S III - Sanpdragon v4, Cortex A9, 1.x GHz dual core     around 38,000/-

Samsung Galaxy S II - Snapdragon v3, Cortex A8, 1 GHz dual core         around 30,000/-

Sony Xperia S - Sanpdragon v3, Cortex A8, 1.xGHz dual core                   around 28,000/-

HTC One X -  Sanpdragon v3, Cortex A8, 1.xGHz dual core                     aound 25,000/-

Sony Xperia Sola/U -  Sanpdragon v2, Cortex A7, 1GHz dual core          19,000/- / 13,000/-

Micromax Ninja A100 -  Sanpdragon v2, Cortex A7, 1GHz dual core      9,500/-


3. RAM & Internal Memory

                                           This is my most exciting area of study because it's change your buying option when you choose particular  model. Take example of Sony Xperia Series.

All model has RAM 512 MB

Sony Xperia Tipo : Internal Memory - 2.5 GB, memory slot upto 32 GB                    10,000/-

Sony Xperia U : Internal Memory - 8 GB ( 4GB for user), No memory card slot        13,000/-

Sony Xperia Neo L : Internal Memory - 301 MB, memory slot upto 32 GB               17,000/- 

Sony Xperia GO : Internal Memory - 8 GB, memory slot upto 32 GB                        18,000/-

Sony Xperia Sola : Internal Memory - 8 GB, memory slot upto 32 GB                       19,000/-

Sony Xperia P : Internal Memory - 8 GB, memory slot upto 32 GB also 1GB RAM  22,000/-  


Tell me which one you buy? Xperia Sola/U/P has Dual core 1 GHz processor other has Single core 1 GHz processor.

Same thing you should see in Samsung, HTC, LG. Samsung has ace, s, y, also in dual Sims. HTC has desire & one series. in those x,v,s,c. What would you buy?


Answer is What's your needs?  more music, more movies, more pictures get extra memory card no need to use internal memoy. But you need more apps from play store, more games you must have more internal memory because apps can't run smoothly from memory card.

 

For info ICS 4.0 can run with 512 RAM or higher.


4. Display

                Here comes most twist-able decision because when you select a phone with with higher processor, ram, memory & you find out display is 3.5" holy crap!!! now what? You actually think Company has to design according to user configuration devices. Sony Xperia U (my favorite one) has a same problem. it has processor & RAM which is in 22,000 phone but display is 3,5" & also no extra memory card slot.

just forgot that phone right now, 4 kind of displays are available TFT, LCD, LED, AMOLED.

well it's use for contrast. you are in day light in middle of the market. then in phone you need to contrast that in the light can see phone's screen perfectly. best result is shown in AMOLED. if phone has this screen forget all other display fector like ppi, color display or resolution........but if it's not then need to be understand which one is better.

 

TFT < LCD < LED < AMOLED

  

We all know about VGA (640X 480 ) resolution. different relational resolution is used in phone which are like QVGA (320 X 240), HVGA (480 X 420), WVGA (800 X 480), FWVGA (854 X 480). resolution is higher image is shown more accurate. also needs more processing power. 


QVGA < HVGA < VGA < WVGA < FWVGA



ppi : part per inch How many pixles are in one square inch area is called ppi. Higher ppi is good for Display.


5. All Other Factors

                         

  • higher version of android is better than older.

 

  • Interface of different devices are just software, it can't change hardware. So, Samsung, HTC, LG, Sony. All of them use same hardware which described here, they only change interface Timewise or Touchwiz or sense whatever they called. also change in material of outer body of mobile, camera, speaker, wifi, Bluetooth, modem, etc. but processor, RAM, Display are one of described here.

 

  • For Games crazy people. There are 3 Graphic interface is available Adreno, Mali, SGX. Most of mobile phone comes with Adreno, Mali is outdated, SGX is product of Samsung,but they only use in higher version of Samsung products and licensing to apple. their versions writen with numbers. e.g. adreno 200, adreno 205, adreno 220, mali 400, SGX 530, SGX 540. Higher number is better. 

  • Sensors: 

  1. Accelerometer - linear movement  of mobile for auto rotate screen.

  2. Gyrometer - same as Accelerometer for auto rotate screen but works better than accelerometer.

  3. Proximity Sensor - when you put phone near to ear screen will be turned off beacuse of it.

  4. Compass - Point out north direction.

 Which one is best?


  1. Snapdragon v4/v3, 1.7/1.5 GHz Dual Core, Cortex A9 with 4.7/4.3" screen, AMOLED, 1 GB RAM, 8/16/32 GB memory, SGX 540/adreno 220 GPU.

                                                                    Android 4.0 supported

                                                                    This configuration not come under 25,000 RS. 

  • Then, Snapdragon v3/v2, 1.2/1.0 GHz Dual Core. Cortex A7/A8, 3.5/4.0/4.3" screen,  AMOLED/LED, 1 GB/512 MB RAM, 4/8 GB memory, SGX 530/adreno 210/adreno 205 GPU.

                                                                    Android 4.0 supported

                                                                    This configuration range 15,000 to 25,000 RS.

  • at last, Snapdragon v2/v3, 800 MHz/1 GHz Single Core, Cortex A7/A5, 3.0/3.5/4.0" screen, LCD/TFT/LED, 512 MB RAM, 2/4 GB memory, adreno 200 GPU

                                                                    Android 4.0 supported

                                                                    This configuration range 8,000 to 15,000 RS.



So, if you find model Less then this prices with higher configuration, it must be on your watch list.

Intel partners Google to make foray into Smartphones



With an aim to expand its presence in the computing world, technology giant Intel on Wednesday announced that it has partnered Google for accelerating its entry into the smartphone market by the first-half of 2012.
It has also promised to bring power-efficient and affordable ‘Ultrabooks', a sleeker and lighter version of laptops, to the market this holiday season.
Announcing a new partnership with Google for accelerating its smartphone business foray, Intel President and CEO Paul Otellini said he was hopeful of Intel's technology-based smartphones being launched in the market by the first-half of 2012.
Delivering the keynote address at the Intel Developer Forum (IDF) here, Mr. Otellini also announced that Intel's engineers were working on a new class of platform power management for the Ultrabooks that will help in producing always-on-always- connected computing.” Today's announcement follows the two companies' recent joint initiatives for the use of Intel technology on Google products, such as its Chrome operating system, Google TV and the Android software development kit.
The company unveiled a computer with a processor running on a postage stamp-size cell powered by solar energy.
Asserting that power innovation would reach unimaginable levels, he said Intel's researchers have created a chip that powers up a computer processor on a solar cell the size of a postage stamp. The computer had its solar-powered CPU drawing sufficient power to run animation and other Windows-based computing processes from two small overhead reading lamps.
However, only the processor was being powered by the lamps and other parts of the computer were powered through a traditional power supply.

The Droid Bionic is the Lee Majors of Android phones: Better, stronger, faster.


The Droid Bionic is here and it’s bringing with it some impressive firsts. It’s the first dual-core LTE phone on Verizon, it’s the first to record 1080p on Verizon and it’s the return of sorts for Motorola as it fields a true flagship device on the partner network that launched its Android career.
The Droid line, although generated in a marketing meeting by Verizon, has become synonymous for many with Android in general. People don’t ask for an ‘Android’ phone, they ask for a ‘Droid’. This has always lent the phones that have come in this lineup an extra bit of cachet, whether deserved or not. After a couple of lackluster outings in the Droid uniform, Motorola is aiming for the stars with the Bionic. It’s beefy, it’s packed with goodies, but is it worthy of the pole position? Lets find out.

Design and hardware

The Droid Bionic is built well. There is a nice heft and solidity to it that is lacking in its otherwise well-designed Samsung cousin, the Nexus S. The angular Motorola feel is here, but it’s been tempered significantly since the Droid 3 and the lack of a physical keyboard has cut some of the fat from it so it doesn’t feel as bulky. The back of the device has a nice soft touch coating that, while it does gather skin oil a bit more than a shiny surface would, makes it easy to hold in one hand without fear of it sliding out.

The edges and angles have all been bullnosed, which makes it more comfortable to hold it resting against the edges of your hand than it would be if they had chosen to finish it off with hard corners. The traditional soft-touch buttons are there at the bottom of the screen, followed by a small but noticeable chin that is emblazoned with the Verizon logo and a microphone hole. The logo is one of two on the front and four on the back, continuing the Verizon (and Google) tradition of over-branding their devices.

It gives it a sort of Nascar feel to have all of this signage on it. It’s annoying and could easily be done without. The simple Motorola ‘M’ on the back would have sufficed, but that is unlikely to happen when all of the partners in this device feel that they have to leave their mark.

Other than that it’s a fairly handsome device. The back of the phone reveals a hump near the top which houses the radios and the camera. This makes it slightly thicker at the top but overall almost the exact same thickness as the Nexus S. The phone is 4.92″ long x 2.63″ wide x .52″ thick and weighs in at 5.57 ounces. This makes it slightly thicker than the .5″ Droid 3 at the fattest point, but slightly lighter than the Droid 3, which weighed in at 6.5 ounces. It is still far, far thicker than the Galaxy S II or the iPhone 4 which clocks in at .36″.

Hardware-wise the Bionic is something of a Frankenstein device. It has the Texas Instruments 1GHz OMAP4430 Dual-core processor of the Droid 3, along with the Droid X2′s 4.3″ qHD screen. Those come paired with the LTE radio of the Droid Charge and it also packs several other radios for global use, as with the Droid 3. It really is a fusion of the Droids that have come before.

Display and Accessories

Honestly the 960×540 qHD screen, which clocks in at 256ppi is a little underwhelming at a 4.3″ size. It’s plenty sharp enough for text but its not as sharp as the 300+ ppi screens out there like the one on the iPhone 4. The PenTile screen means that you also get the traditional ‘mosaic’ effect that makes it appear as if the pixels are laid out in a visible grid. It’s subtle, but noticeable, especially when lighter colors are being displayed.

It also doesn’t have the advantage of the Super AMOLED Plus technology that the Infuse 4G or Nexus S uses, so the screen isn’t as vibrant and punchy as either of those phones. The TFT tech used also means that the viewing angle is a little narrow, although that doesn’t matter as much on a phone as it does on a tablet.
The Corning Gorilla Glass topper is very nice though, and the dual anti-glare coating makes it pretty easy to see in various conditions.
The Bionic has the exact same ports as the Droid 3, featuring a Micro-USB, Micro-HDMI, volume buttons, 3.5mm headphone jack and a power/sleep button. It also packs in 16GB of built-in memory and a Micro-SD slot that will take up to 64GB more.

The package we received for testing came with just the power adapter and USB cord, no HDMI cable. Verizon is selling two accessories that are aimed at expanding the Bionic’s capabilities in a way that mimics the Atrix. There is the Webtop, which is a dock that connects your phone to a computer and the Lapdock, which contains a keyboard and trackpad. The Lapdock will set you back a cool $299, but there is a $100 mail-in rebate that requires you purchase it with the phone and a $50+ data plan. We weren’t able to test either of those.

Cameras

The quality from the rear-facing 8mp camera is decent, but nothing to get excited about, and that’s in good light. Once you get into poorer lighting conditions, the quality goes south fast, even with the flash. If you’ve got a decent amount of light, you can get shots that will document what you’re seeing, but you’re not going to rush home and print these out. Even on-screen the colors seem muted and lack contrast and saturation. It’s hard to determine whether this is a fault of the sensor or the processing chip, but either way, it suffers from the same camera deficiencies that the Droid 3 did.

There is also the matter of the camera’s response times, which are downright atrocious when it came to auto-focusing and firing. I counted off upwards of a 10-second delay at times waiting for the camera to get around to firing, while other times it would pop right off. It makes it difficult to trust the Bionic to fire off a shot just when you want it to.
Popout
The front-facing camera has even less to impress with and turns in a barely-there performance that should be adequate for video chatting in decent light, but not much else. Grainy, desaturated and generally not that great.
Neither of the cameras turn out a great still image, but thankfully the rear 8mp camera does pump out a very nice looking 1080p video. I don’t know where the logic is in the video looking so much better than the stills, but the fact remains that it does. Crisp, good framerates and spiffy saturation.

The video quality was a nice suprise after the relatively disappointing images. The iPhone, or even the Infuse 4G takes a better still, but neither of them shoot 1080p video and they would be hard pressed to do so at this level of fidelity anyway. The dual-core OMAP4430 is really showing its power here, good stuff.

Performance, voice and battery life

Fast, fast, fast. The Droid Bionic absolutely screams speed-wise in every way. The 1GB of RAM, the dual-core OMAP4430, Android 2.3.4, LTE – it’s all working together here to produce one of the fastest, smoothest Android experiences that I’ve used. Even Motorola’s on-again-off-again Motoblur enhancements couldn’t make this baby chug. Flipping around the ’3D’ home pages and visually impressive widgets was buttery smooth and gave off no stench of framerate problems.

Maps, pinch-to-zoom, all of the little problem areas that you normally look for framerate problems to crop up. The Bionic aced all of them with flying colors.
Traditionally, Motorola’s skin has caused some major issues with even beefy processors like the 4430, but, for whatever reason, it blazes here. This is also reflected in benchmarks, where the Bionic turned in some incredibly impressive numbers, coming in at just under the Samsung Galaxy S II and LG Optimus 2X in our tests with System Benchmark. The PowerVR SGX 540 acquitted itself nicely as well, with smooth framerates in any 3D games we tried and solid scores in benchmarking.
The call quality was good, without any remarkable level of clarity, but also nothing to complain about. It sounds pretty much like any of the Motorola models you’ve used lately I suppose, nothing really all that interesting to say here. We were unable to get any calls to drop or even for the signal to fall below two bars for that matter.
The LTE speeds we got were blazing here, although in the wilds of central California, there isn’t nearly the network congestion of New York or San Francisco or any other large city. The speeds topped out at 16.31Mbps and remained in the ballpark fairly consistently throughout our testing. Where the signal fell, so did the speed of course. But if there was a solid LTE signal, the connection was blazing.
On the whole, the 1950mAh battery seemed to acquit itself quite well, with about 25-30% battery left after a solid 8 hour day of heavy browsing, 3D gaming, video watching and syncing two Google accounts, along with a variety of social accounts to apps and widgets. It really is surprising to see this kind of performance out of an LTE equipped device, especially after the disappointment of the Droid Charge, which leaked power so fast it was nearly impossible to use LTE without plugging it in.

Software

The Bionic comes juiced up with Android 2.3.4 and the model that we got for testing had the Motoblur enhancements still installed. We were under the impression that Motorola didn’t want us to call it that any more, but the documentation that we have still refers to it as such, so we will here as well.

The ‘enhancements’ consist of icons that are slightly smaller than standard 2.3 icons and a bunch of fancy widgets including a nice quickdial interface that shows off the processor’s transparency and animation prowess. In addition, you get the aforementioned ’3D look’ home screens that feel a lot like Honeycomb on a tablet. There is also some system-level tweaks like a predictive dialer and reskinning of almost every standard Android component.

There is also a variety of Verizon crapware installed on the device, most of which you will probably never touch. There are a couple of nice bits of software loaded on as well though, like a full version of Zumocast, for playing content from your computer, the Kindle app, VZ Navigator and pretty much every Google app known to man.
Verizon told us that Motoblur would be an optional install for the customer, and that it would not be required to activate or provision the device. This should mean that you can run the Bionic with a completely stock version of Android 2.3.4. If you can manage to make this happen, I highly recommend it. Stock Gingerbread is quite nice and beats out pretty much all of the third-party skins aside from perhaps Sense.

Conclusion

The Bionic turned out to make it work as a fusion of the last few Droid models. It manages to maintain the Droid aesthetic, but transform it into something that’s lighter and more comfortable to hold than its predecessors.
Not everything about the Bionic is successful though, the sluggish and poor quality camera, and the pattern-plagued screen come to mind as bits of the device that we would love to see improved. The camera is terrible when compared to other Android units and off the charts bad when compared to the iPhone 4, a phone that is a year and a bit old.
The interface also feels fairly cluttered with extraneous, albeit pretty, widgets, which you have to clear out to make it feel more organized. The Motoblur enhancements are also unnecessary, but the word from Verizon that they’re optional gives us hope.
The Bionic makes a case for being called the Droid line’s new flagship model, and it makes it well. The epic speed of the LTE network, coupled with the dual-core processor make this a force to be reckoned with when choosing an Android device on Verizon and puts it in the top-tier of Android devices from any manufacturer. Now we just need to pit it head to head against the upcoming Sprint Galaxy S II Epic 4G Touch Disco Foxtrot Electric Boogaloo Edition.
