More images of the upcoming device trickle out of southeast Asia

New images have been leaked of Microsoft Corp.'s (MSFT) upcoming midrange Lumia 830 device.  The new smartphone is expected to be announced sometime in September, likely shipping late that month or in early October.

The new device is expected to have an aluminum frame, similar to the Samsung Electronics Comp., Ltd. (KRX:005930) (KRX:005935) Galaxy Alpha.  While it can't quite keep up with much higher priced premium devices such as the Galaxy Alpha, the Lumia 830 is nonetheless a major upgrade over its predecessor, the Lumia 820.

Aside from the rather radical body change away from a rounded-edges pure-plastic model, there's equally compelling upgrades to the hardware spec, from the previous generation model, the Lumia 820.  Where as the Lumia 820 had packed a 4.3-inch SVGA (800 x 480 pixel) display, its successor is expected to carry a 4.5-inch 720p (1,280 x 720 pixel) display.  The processor is also expected to receive an upgrade.

Lumia 830

The biggest improvement, though is the inclusion of a shiny new 20.1 megapixel sensor.  Thus far only a handful of more expensive devices have packed this kind of imaging power, including several models in Sony Corp.'s (TYO:6758) Xperia Z Series (the Z1 Compact, Z1S, Z2, and upcoming models), Samsung Galaxy K Zoom, a couple of Lumias (the Lumia 1520 and Lumia 930).

Given the 20.1 megapixel resolution (subtly different from Sony and Samsung's 20.7 megapixel sensors), it's highly likely this sensor is a Toshiba Corp. (TYO:6502) module.  Further, aside from the Lumia 920, which used a 8.7 megapixel Sony EXMOR sensor, virtually all high end Lumia devices analyzed were found to carry Toshiba sensors.

Lumia 830 back face

We the Lumia 830 to carry Toshiba's T4K46 chip, which was made public in March 2014 and was expected to enter mass production in Q3 2014.  The sensor packs 1.2 µm square pixels (in a 5,216 (H) × 3,920 pixel layout).  The sensor footprint is 1/2.3".  The sensor uses back-side illumination (BSI) which has been the case for every known Lumia sensor.  (BSI generally yields superior results to the front-side illumination (FSI) used in the non-Windows Phone Nokia PureView 808, as the illuminating layer doesn't block incoming light).

The sensor is expected to be paired with a ZEISS PureView optics module from Carl Zeiss.  As with past designs, this is expected to feature several plastic lenses (typically 5) and a single glass lens, which together carry out the optical image stabilization (OIS).

In testing by the PureView Club, Sony's 20.7 megapixel EXMOR sensor was compared extensively to the previous generation 20.1 megapixel Toshiba sensor.  The overall finding was that the Toshiba sensor produced a slightly underexposed image, while Sony's sensor tended to overexpose (wash out).  Generally, underexposure is more desirable as it can be more accurately post-processed to a neutral exposure.  The ZEISS optics package was also better at focusing during close-up photography.

The LED module appears to be a single LED flash, which isn't terribly surprising at this price level.

The phone features pretty standard side buttons -- a volume rocker, power button, and camera button

Lumia 830 buttons

The location of the headphone jack appears to have shifted from the right side of the top face (when looking at the device screen) to the center, an interesting design tweak. The microUSB jack has been shifted to where the headphone jack was previously.  This may be to better accomodate the phone when charging in your car, where users often rest their device in a cupholder.

Lumia 830 top

The images show that the device has physical buttons (although the virtual buttons are still showing up in the firmware).  The phone is expected to run Windows Phone 8.1 Update 1 and the new Debian Red firmware.

The photos in this piece were leaked from China by microblogger/leaker @WP7Q1ng (get it, Windows Phone 7 "king"?).  It's well known that China is where most high-end Lumia devices are painstakingly assembled. Not surprisingly, it's also the source of many of the leaks we received during the wind up to device launches.

The Lumia 730, 830, and possibly another device will likely be unveiled at the IFA 2014 (Sept. 5-10th) mobile electronics trade show in Berlin, Germany.

Why is BSI inferior to FSI?

so the name is a bit misleading, as it is essentially a flipped-over sensor, meaning the backside of the sensor is exposed to light entering it.
from the graph they show this seems to be the better way of doing it, not the worse way. the back-end stuff needed to process the image is really on the back with BSI, whereas it appears to limit the amount of light that reaches the image sensor in an FSI setup.
so i think the DT article has it wrong... but i am no expert.

The conclusion is that BSI is superior to FSI in performance, but not cost-effectiveness.
So why does the article state that BSI is inferior?

I am an expert - BSI is superior to FSI in any smartphone or smallish-camera type scenario. The dailytech article is wrong.

By amanojaku on 8/15/2014 10:57:59 PM , Rating: 3
It's not, the article is wrong. BSI is better because the sensor is not obstructed by the matrix wiring, so more light is captured. More light = better quality photo, usually.

There are several reasons the 808's PureView FSI sensor was better than pretty much all contemporary BSI sensors: >4x the megapixels of the next-highest Nokia phone (41Mpx vs. 8.3Mpx), a larger image sensor than other cameras (>4x the surface area of the iPhone 5s and Lumina 820), and large sensor pixels (1.4 µm vs. the typical 1.2 µm). The device was able to capture so much image data that it threw out much of it, or combined the results of multiple sensor pixels into one image pixel.

It's worth pointing out that the Lumina 1020, the 808's successor, has a 41mpx BSI. This replaced the 808's FSI as the best sensor available. The 1020 has smaller sensor size than the 808 (about 80%), but technology has improved to where today's smaller sensors offer quality compared to yesterday's larger sensors. And the sensor pixel size is 1.12 µm. From what I've seen, colors are more accurate and images are sharper on the 1020, most likely due to the switch from FSI to BSI.

Everybody knows the epic sensor on the Lumia 1020 is the best in the business. Simply improve upon that design and release a godlike phone with it already and stop wasting time.

Seriously, they should just make a 4.5", 5" and 5.5" version of the Lumia 1020 all with that awesome camera and similar specs. Give people a reason to buy Windows phones.

Some people can't afford top-of-the-line phones for various reasons (such as buying off contract phones and using them on a cheaper network). Hence entry level and mid-range phones. This is one of their mid-range phones, and is a HUGE leap above the older 82x models in every way possible. It's hardly a "waste of time", and phones like this very nicely fill the gap between the budget models and the high-end devices.

With that being said, yes they need to replace the 1020 and I'm sure they're working on it.

So far Nokia's best WP success was pushing quality down in price with the Lumia 520, looks like they're using the same strategy with this imaging handset by pushing a high quality camera down in price. Putting that camera at a mid-range price would be a first and a nice USP. I think the closest competitor would be the more expensive Z2.

In low light yes, everything else it's still the best but others are catching up.

I like my phones to be more uniform though as I hate the massive bump on phones sporting a larger sensor. Instead of going for thinness OEMS should just even out the space by adding a larger battery to it.

have you ever tried zooming in with multiple phone cameras?

Only phones around that can go head to head with the 1020 are: 808, Galaxy Zoom on a good day, Galaxy K Zoom on most days. the original zoom wins in places with good light if overt 3x zoom is needed, and lens speed is not to high. Galaxy K wins almost every time over 3x zoom is needed.

That being said, you sound like you never have used the 1020... Of course, I would argue that almost all highend phones are good for everyone for most kinds of shots, and, almost all produce "good enough" shots for most things.

A high Rez camera is not a reason to buy a phone. You might have noticed that all of the high Rez phones mentioned in the article are low selling phones, actually, pretty low selling phones.

If people don't want the phone for other reasons, these cameras aren't going to change their minds.

Actually, "read" is more appropriate because it refers to a past action on the article in question. "Reads" implies someone periodically checks each article for errors AFTER publishing in order to correct them. We know that's not true as far as DT staff goes. We're the proofreaders.

But this is DailyTech, not DailyGrammar. As long as the meaning is clear I can live with typos. It's the factual errors that piss me off, like the article originally saying FSI is better than BSI!!!

Yea this is totally wrong. There have been numerous Lumia phones that are not BSI. The Lumia 900 didn't have one, and that was their flagship at the time. I remember numerous articles comparing it's ~8MP camera to the 16MP HTC Titan II, and a big difference was the HTC's phone contained a BSI sensor and it produced much better images than the Lumia's at that time.

Looking at Daily Tech's recent stories proves everything you wrote to be the word's of a stupid troll.

Be it "Microsoft barely beating RIM", with a story showing MS having 5 times as much market share.


"In 2014, all phones have 5" 1080p displays and 20Mpx sensors." When Samsungs new Galaxy Alpha is 720p.

Just go take a second and actually read a story before posting.

He's right. This phone is trash.

Rather than spending money on advertising and constantly pumping out worthless Lumias, they could just make a phone that actually competes.

Apps don't even matter now. I use 3 apps on my phone, Skype, Kik Messenger and micoach.

Man how spoiled are people like you that anything that isn't top of the line is trash? Are you so full of yourself that you can't imagine anyone not needing a 4K 5" screen and quad/octa core processor? Some people are happy with a cheaper device that might not have as good of specs but still more than gets the job done.

I swear the sense of entitlement here is getting absolutely retarded.

I think what he's saying, in a crude way, is it would be nice if just for once Nokia made a balls-out bonnafied halo phone to compete with the likes of the LG G3 and Galaxy S5.

Every model doesn't have to be high end, no. But can't they just make ONE model that really "wows" people?? That's always been absent in the Windows Phone world, and they really are suffering because of it.

Go to the review sites if you don't believe me. NOBODY is talking about Nokia phones because...well, there's nothing to ever talk about!

I was about to reply to vision33r, but two sentences into his post and I could see he was either trolling or stupid. I'll reply to you, instead, because you're neither. But...

Neither of you seem to be aware of the Nokia line. The flagship is the 9xx series, currently the 930. It's specs are equal to that of other flagships like the S5 (>2400mAh battery, quad-core >2.0Ghz CPU, 1080p AMOLED display, 2GiB RAM, 32GB of internal flash storage), and is a hair behind the G3. Purely based on specs there's no reason to ignore the 930.

Consider this: the iPhone's specs are about half of the 930's, and it sells.

Yes but again, it's merely AVERAGE for a flagship. No SD Slot or user replaceable battery though, and it's battery life is rated pretty poor.

Also why are Nokia's so cludghy and heavy? This thing only has a 2,420 mAh battery, and it's 167g's!

The 930 is such an incredibly underwhelming product, when Nokia needs to be going for the brass ring. With 2% marketshare, "good enough" doesn't cut it.

Only on-par with other flagships, oh dear! I guess being built solid is a downside now? Also I've read several reviews that rate the Icon's battery life as being good.

The 830 is spec'd like a decent midrange phone, which is what it is. Far from "trash". Maybe if they were Android phones suddenly the specs would be fine...

I would buy an HTC M8 for Windows 8 before I bought the Icon. Just my opinion. NOTHING about the so-called "Icon" stands out or offers anything new and exciting. And it's visually boring, like all Nokia's.

Built solid? Please come off that. Aside from the iPhone, nearly every smartphone out there is build solid.

Do you understand that Windows Phone has like 2% marketshare? Being "built solid" is NOT a convincing selling point!

And why are you putting "trash" in quotes? I did NOT call this trash.

Try selling this phone at a VZ/ATT store next to 3 other phones that has this Nokia Lumia phone beat in every spec category. Maybe the camera on the Lumia can still hold up but that's the last saving grace.

Display: G3/HTC/S5/iP5S > Lumia
Weight: HTC/S5/iP5S > Lumia
Processor: HTC/S5/iP5S > Lumia
Internal storage: HTC/S5/iP5S > Lumia (where is the 64GB??)
thickness: iP5S/S5/HTC m8 > Lumia
Camera: Lumia/S5/iP5s > HTC m8

If you think this is troll post, just look at all the out dated phones Nokia keeps churning out before you call me a troll.

At an existing AT&T store now though, they have the Lumia 1520, which contains a better screen in my opinion than all of the models you listed, a better camera than all of them as well, internal storage only goes to 32GB but with WP 8.1's management of SD cards and the ability to throw in a 128GB card into it makes that point moot. It is quite thin as well, but given it is a 6" phone it is quite large so others might not prefer that size.

Err negatory.

The display on the G3 just consumes too much power relative to its immediate competition, even with an always-on chip that auto-dims it when using manual brightness settings. Meanwhile, the resolution of an iPhone 5/5C/5S is less than 720p. Math must not be your strong suit.

That leaves the HTC and S5 against the Lumia. Yeah, well, the flagship for Lumia's is the nearly phablet-sized 13xx/15xx. This isn't it.

I'm at the point where the lighter the phone, the worse its ergonomics and handling are. Can't stand its 167g weight? Go work out some more, fatty. My SGS4 weighs double that in my pockets and it's nothing.

Comparing flagship Android/iOS phones against a midrange WP... yep, you're comparing apples and oranges here.
Internal storage

An iPhone 5S unlocked 64GB costs $900 before taxes. That's immediately 50% more expensive than so many other flagship phones, it's not funny.

830 isn't a flagship by any stretch of imagination.

I absolutely hate thin phones with a passion. Like the weight argument, thinness does ergonomics and handling no favors. Most people use a case with their phones, thereby making them thicker... so what's the point of a thin phone?

You're still trolling.
