Hi friends:
Just upgraded from my Nokia N73 to a Nokia N82 on 31st Dec. 2007.
Bought it (peti-pack) from TheMobileStore for Rs. 24,499 less free gift worth Rs. 5,000. Nokia announced this phone barely 45 days ago. The MobileStore - Best Mobile Phone Deals, Buy Mobile Phone, cell Phone Accessories
The operating system is Symbian OS version 9.2 with S60 rel. 3.1 GUI.
The GPS is just awesome. Beats all my experience with borrowed N95s.
Other cool features include 802.11 B/G WiFi and FM stereo tuner. It has a 3.5 mm audio output jack, so you can plug in your hifi headphones directly.
One of the top features is the 5 megapixel camera (2592 x 1944 pixels) with Tessar lens from Carl Zeiss. This is the famous Tessar four-element design.
The front element is a positive crown glass element, center element is a negative flint glass element and the rear element is a doublet comprising a negative plano-concave flint glass element cemented to a positive convex crown glass element.
Maximum aperture is f/2.8 at wide narrowing down to f/5.6 at telephoto.
First time for Nokia is a built-in Xenon high intensity discharge flash.
The phone came with an installed 2 GB microSD flash memory card with hot swappability.
It has built-in GPS navigation with additional Assisted GPS (A-GPS) for fast tracking.
Nokia has also integrated an accelerometer (with user-interface auto-rotate). When you rotate the camera, the screen automatically switches from portrait mode to landscape mode.
The very good browser automatically toggles between portrait mode and landscape mode, depending on how you orient it w.r.t. earth's gravity! Here is Team-BHP on the laptop and on the Nokia N82.
At last the phone has a 3D Graphics hardware accelerator (OpenGL Embedded Sys. 1.1) and analog video signal output for direct connection to a TV set.

The N82 packs a formidable set of features into a single package.
for example: How many other cell phone models have all of these (as in: every single one of these features)? - Built-in accelerometer with automatic screen rotation
- 3G/UMTS radio
- WiFi.
- Quad-band: WCDMA2100 (HSDPA), EGSM900, GSM850/1800/1900 MHz (EGPRS) with automatic switching between bands and modes
- Texas Instruments OMAP 2420: i.e. 332 MHz ARM11 + 220 MHz C55x DSP + PowerVR MBX GPU,
- 3D with Graphics hardware Accelerator (OpenGL ES 1.1) -- Direct connection to TV via TV-out or wireless LAN/UPnP
- Phenomenal 5 megapixel CMOS camera sensor with real (Xenon) flash, Carl Zeiss Tessar (4-element) autofocus lens; Secondary (front) camera
- MPEG-4 VGA (640x480), 30 frames per second video recording
- Upto 32 GB Hot swappable microSD memory card expandability
- Stereo FM radio
- Integrated Stereo speakers
- 3.5 mm audio jack
- A2DP wireless stereo Bluetooth headphone support
- Integrated GPS receiver for navigation with Assisted-GPS capability
- full n-GAGE gaming platform
If I were to somehow trash my December 2007 model N82, I would just buy a new N82. Otherwise I'd have to "double" the budget to look for a worthy competitor. |
Friends, I have the following experience to share.
The camera in my 20-month old Nokia N82 had stopped working. Maybe it was a fall a few days ago.
I was devastated. It was such a handy and performing camera, Xenon flash, 5 megapixel... -- the "benchmark" cameraphone for low-light photography. For sheer computing power, the N82 came with dual ARM 11 332 MHz processors and 3D Graphics hardware accelerator, that few phones even today can boast of.
I thought I should get a new Nokia N82.
But bad luck!
In 20 months since launch, Nokia had discontinued the darned thing!
Worse, I found out that Nokia had elected to discontinue the use of the brilliant Xenon flash in new mobile phones.
What? Why? Space Compromise
The Xenon flash operates at 330V and requires a bulky storage capacitor.
Space is a significant factor in mobile device design.
The bulky electrolytic capacitor takes more room inside the phone body, than the designers are willing to grant it.
Energy Compromise
Besides, this capacitor takes time and energy to charge after every flash discharge.
That exacts a toll on battery life.
From a power reusability perspective, the electrolytic capacitor's charge can be only used for the flash.
but the charge in the thin film supercapacitors used in LED flash, can be reused for powering GPRS, Radio-Frequency Transmission, Audio, etc.
Durability Compromise
Also the the Xenon gas-filled glass Flash tube is fragile and susceptible to crack if the phone falls to a hard floor.
Safety Compromise
Then, it is a safety problem to assemble the highly charged capacitor without frying other circuits.
Simplicity and Cost Compromise
Moreover, the Xenon flash requires a mechanical camera shutter.
This translates to extra cost, power consumption and space occupation
whereas LED flash can be used with an electronic rolling shutter.
It's also a simple given that a Xenon flash tube costs more than an LED.
Functionality Compromise
And when one is shooting video, one needs a separate LED light.
The Xenon flash is unusable as a video light.
With all these compromises, the Xenon flash is regrettably a thing of the past in Nokia cameras.
That's that, even though everybody knows that
compact digital cameras made by Nikon, Olympus, Canon, etc. always feature Xenon flashes. Never LED flashes!
But these CDCs only take snaps, nothing else.
A cameraphone after all, has to be more versatile than a digital camera.
It has a GSM transceiver, a Bluetooth transceiver, an 802.11 B/G WiFi transceiver, a GPS satellite receiver, an FM transmitter, an FM stereo receiver, a graphics accelerator with TV out, an accelerometer, a magnetometer compass, a PDA, an MP3/WMA/WAV/RealAudio/AAC audio player, an H.264/MPEG-4 AVC compressed video player...
Be that so,
I still felt, the Xenon flash was a darn good thing to have.
It would fire and sustain intense full-spectrum white light for a fleeting 20 microseconds. That's 1/50,000th of a second.
In that duration, a car going 100 km/h across the frame would barely cover 0.5 mm. So you could get a nice frozen shot and could count the spokes in the wheel.
I was really sorry to think that my N82 camera was dead.
And even sorrier to learn that there were no more N82s to be bought anywhere in Mumbai, not even in Nagpur.
Goodness, I must have gone to a dozen different areas, to check the shops.
Searched the web for a replacement cameraphone.
It had to be a Nokia with its mature Symbian OS.
I don't like touchscreen phones. 12 years ago, I had a Casio Cassiopeia running Windows CE 1.0. This had a touch screen and even software to let you scribble some drawings. Then 8 years ago, I had a touchscreen Palm Pilot with its Graffiti handwriting recognition software.
Some part of me still sees touchscreen phones as showy gimmicky gadgets -- no more.
So it had to be the new Nokia N86 8 megapixel camera phone.
It has a variable aperture Carl Zeiss Tessar optic.
And wide angle (equivalent to 28 mm on a 35 mm camera format)
Like the N82, it has GPS & A-GPS, WiFi, Bluetooth A2DP, ...
Extras are -- even a magnetometer compass and a good FM transmitter for my car stereo.
But it uses two LEDs as flash. No more Xenon flash!
When I was just going to go out and buy a black Nokia N86 8 megapixel cameraphone, this afternoon, pleasant serendipity struck!
The Nokia N82 fell out of my pocket and took another hard knock.
Wonder of wonders! The camera started working again!
So happy that the N82 has some more life left.
