These are the first photos of the Lumia 730 and new 'Debian Red' firmware

New photos of Microsoft's next mid-range phone, codenamed Superman, reveal a bright green Lumia 720 successor is being developed, along with new firmware.

Two new Lumia phones, thought to be the 'Lumia 730' and 'Lumia 830' are reported by the Verge as arriving in the next few months. Recent images leaked of the Lumia 830, which is thought to have the codename 'Tesla.' Now, the first photos of what is understood to be the Lumia 730, codenamed 'Superman' have been obtained by Windows Phone Central.

The Lumia 730 looks to be the successor to the Lumia 720, one of the more popular mid-range phones by Nokia announced in early 2013. The Lumia 730 is aimed at the growing 'selfie' market as it allegedly features a 5 MP front-facing camera and a 4.7-inch display. Additionally, the Lumia 730 looks to carry on the bright green color scheme found with the Lumia 63x, Lumia 930 and Lumia 1520 series and features on-screen keys.

Not much else is known about the phone at this time, although we are attempting to gather more information on specifications.

There is also evidently new firmware being developed for this phone that likely coincides with Windows Phone 8.1 Update 1 or even Update 2, which is thought to arrive in November. The name of this firmware is 'Debian Red,' which is the actual name of a color, though more often associated with the Linux Distro. However, Debian Red' is very likely the internal codename, similar to how Lumia Black was originally called 'Bittersweet Shimmer' and Lumia Cyan was 'Cherry Blossom Pink.' The firmware names go in alphabetical order, starting with A for Amber, Black, Cyan and now D for Debian Red.

Any features of Debian Red, including improvements or optimizations are currently unknown, although we are working to find out more.

  • Debian Red? Okay than.
  • It's likely to be just the internal codename as stated in the article.
  • Like 'Cherryblossom Pink' for Cyan...
  • Was that named after one of the Angry Birds as Bittersweet Shimmer was an album track? And if Debian Red is an internal name they'll have to find another D colour. Denim?
  • How much RAM does it have??
  • Definitely 1gb this time if not them Microsoft will bear some heavy losses.
  • That's right! 720 would sell much more if it was 1gb ram. But it would then beat 820.
  • Nokia always made compromises in each Lumia so it wouldn't affect other models sales they kept on doing this & forgot to make an uncompromising phone & that's how my Friend now Nokia is of Microsoft.L720 should had a 1gb of ram at that time.I hope this upcoming L930 is a successor rather than just a new model for sake just like L530 which makes no sense.
  • doesnt matter,it lacks a camera button from what i see and capacitive keys,not worthy of an upgrade over my beloved 720,rather get a 930 instead even if i have to wait a bit longer for it to release and the higher price
  • L930 too has On screen buttons & Seriously speaking it is a waste of money. You are stuck with 32gigs of onboard storage & its not enough knowing the fact "Others" Section takes up memory for me it is taking 4-6gb now *L920. Just see the specs of L730 once released then think of buying L930. :)
  • Lolwut dude 930 has capacitive keys and camera
    Also 32gb is enough for most people
    I have a 32gb card in my 720 and out of the total 40gb(approx) I still have 8gb free so yeah I don't mind the 930,others may have a different opinion
    Other than the 930 none of the other 30 series lumias have impressed me over the 20 series
    All newer ones seem like downgrades except for the 930 which has a newer design to offer,it may have its drawbacks but its not a bad phone
    The other storage doesn't take more than 1.5gb for both my phones-720 and 820,6gb other storage is a thing of the past for many only a few people have that much today
  • L930 has capacitive keys oops forgot that.I replied to ur comment while having my meal & watching E3's press conference so ma Bad :P Xd
  • most people dont use/need more than 32gb, this obsession with specs is getting way out of hand. No matter what Nokia brings to the table its never enough. i never heard an iphone user complain about only 16gb. They're just happy to use an Apple product. Nokia give u OIS, NFC, wirelesscharge, Zeiss lens, on an OS that actually works with 512mb of ram but nonetheless.... Complaints
  • ^true dat,i myself have a lumia 720(and 820) along with an iPad and I often like to wonder how I got a much better deal than my iPhone touting friends(in India we must buy it for the full price no contract for $900) and still get a better experience than an iPhone with all apple apps and stuff on my iPad(some apps which aren't available on WP but very very few) and can take better photos , great battery life etc with my 720 for a much lesser price
  • But Apple gives the option to select 16,32,64 & now even a whooping 128gb option So why can't Nokia(Microsoft).
  • Because apple only makes 2 different phones (you could say 6 maybe if you classified the storage option as a different phone), where Microsoft/Nokia makes 8 different models of phones...Some have expandable ( up to 128GB expandable) and some don't. I personally wasn't sure how I'd do with 32GB, but with it all backing up I just delete what I don't use and it's all good. Happy with my 920 till we get another high end device in Canada (wife has the 1020).
  • Let it be we don't need iPhones conversations in here :) Hope u'll not regret on 32gb non expandable storage option.Sir u have a nice selection of Lumia's for your family so L730 would be the next phone for your wife because of front 5mp cam ? Xd :)
  • Bittersweet Shimmer was a Crayola crayon colour, seems like the other two aren't though so wasn't a trend Only D colours are Denim & Dandelion, so I'm hoping for Deep Purple
  • Good shout. At the time it was announced, it was tied to the band Fuel who had two album tracks Bittersweet and Shimmer. Stick Dark or Deep in front of any colour and you have hundreds. Or Dusky Pink..
  • What color could start with a D?.. Maybe they'll switch things up a bit.
  • Dirty White.
  • You got that right!!!
  • Probably not since it starts with the letter "D" assuming Nokia wants to keep it alphabetically.
  • Note that Nokia used the internal codenames 'Bittersweet Shimmer' and 'Cherry Blossom Pink' for the Lumia Black firmware and Cyan firmware respectively. So 'Debain Red' fits the trend as an internal codename.
  • Whatever we just want the updates faster as Microsoft now owns Nokia so who knows how it will work.
  • Seem to be a legit name, since its falling in line with the alphabetical naming through colors, even though i never seen this color in my crayola box, but nonetheless......
  • So the next firmware will start from the letter 'D'
  • Lumia Desire, it's a red.
  • It's almost like a light Debian Red. (at least to me. c: )
  • Does anyone get confused like I do about these models. I know they are basically tiers. 500 600 700 800 900 1000 but I still lose track of all these models especially in the 1000s
  • Microsoft needs to stem these madness - get a low end, mid range and high end device - that's it. Applie, Moto etc are already that way.
  • Nope.... You're right about the different models, the 10's (ie. 00, 10, 20, 30) I suppose, denote the generation of that model.
    So for example, the Lumia 920 was released around 18 months ago and was superceded this year with the 930.
  • I don't get confused because it's very, very easy to understand...
  • It's just 1020, 1320, 1520..
  • I think it's easy enough; the last two digits are the revision (00, 10, 20, 30) and the first are the model range (9xx,10xx,7xx,6xx,etc.)  Each model offers different mixes of features and is designed with a specific type of user in mind. I quite like the model naming, and would rather not see something like Apple has with a one phone fits all approach.
  • I think that the way you explained it is amazingly clear, I never thought of it that way, and ai thought I understood the system. I also agree with you when you say this model for naming phones is better than the one Apple uses, or LG. or anyone else
  • 530 is for x users, 630 is for 520 users. That means this is the 620's successor. Hurrah!!!
  • Having a 620, if this thing has 1gb ram+, high dynamics recording, clearblack, and SD slot, I'm sold!
  • Oh yeah, and a much bigger battery! Plus, I want it in that orange color.
  • L730 is L720's successor as it has Pureview technology.L620 didn't had & it is a Low end not a mid end phone.
  • The 720 and 820 had Carl Zeiss lenses derived from the pureview sensor itself
  • Yes it totally sucks! Many young do not like to spend a days to find out what is what! They move on to more logical naming!
  • I find people actually don't move on to more logical naming. Just simple arbitrary naming. With the lumias, the numbers are logical.....
  • It's not that hard, really...
    The front digit denotes the tier (5,6 = low-end; 7,8 = mid-end; 9,10 = flagship; 13,15 = phablet)
    The second digit denotes the generation (0,1 = Mango era; 2 = WP8 era, 3 = WP8.1 era)
    The last digit denotes the variation in the same tier The only exception to this is the 810 which is a WP8 device
    Also, the 1320 could be thought as an anomaly as its number is bigger than 1020 but no better overall than it as the 1320 is 1520's downgrade
  • I wouldn't mind if it actually ran Debian :D.
  • Which is not possible...
  • And illogical,get android if u want Debian on your phone :p(actually no,stick to WP)
  • Cherry Blossom Pink is also an actual color (RGB 255, 183, 197)   My money is on 'Denim' for the final name of the firmware. Just guessing here, but I think it would make sense. Denim is RGB 21, 96, 189 (if you want to see what the color looks like..)
  • or maybe.... Dandelion!
  • Or diamond?
  • They won't go with diamond, it suggests finality. The logical pick from a pr view is desire.
  • Why does this remind me of some womanising poet from the Witcher games? :P
  • DOOM!
  • how nokia works: use red color type name for beta test use other color type name with short length and 1 word count for release and each update are connt from A to Z (amber, black, cyan) (bittersweet shimmer, cherry blossom pink, debian red) next update name could be demin, desire or diamond
  • You got that right!!
  • Then**
  • Lumia debian red!!!! ^^
  • Edited as soon as I sent it through :P
  • Characteristics info?
  • It doesn't appear to have any buttons.
  • Not liking this at all! Particularly if it doesn't have a dedicated camera button.
    I can accept this if it was a cheap low end device, but the 730 is anything but.
  • Camera button defines a Windows Phone! I understand why they have relaxed the requirement for this button - so that third party firms can easily adapt Android devices for WP - but first party devices need to keep it. Maybe not on the 530 etc where every dollar counts but mid to high range need to keep this feature in Lumia phones.
  • Don't bicker until you know the specs, it could easily have a captive button in the bezel. Also, It's to late to change the phone much at this point so when it's released and doesn't have one then send in complaints, we need phones to make it to market at this point. It's been ridiculous what MS is willing to sit on in such fast paced markets.. If he doesn't change or make sure they get it right the first time we won't have any device's left to get market share up.
  • I wont buy a new Lumia without a camera button
  • Exactly, this. It is a defining feature. Not sure the savings in deleting a physical button in the scheme of things.
  • Microsoft sucks in making decisions.Lumia 730 should have a camera button 1.Its has a fucking Pureview technology. 2.It is a mid tier phone not a low end or high end phone.
  • If you look close enough on the picutre you can actually see that it has buttons on the right side of it. I can spot the volume and camera button on the side just like on the 920. It's just that they are in the same colour as the shell of the phone so they are really hard to see. So it actually has buttons, nothing to panic over here, walk along :)
  • Yes, I think I can see a camera button on the photo. I hope so anyway! BTW, this is one of the negative points going against the HTC1/m8.
  • 1gb quad core 400 processor should be there in 730 to succeed in the market
  • Yup , with 1.4 GHz would. Be excellent
  • at least a 720p screen .. it should be midrange in 2014 to take on those low end motos. Flagships can be 1080
  • Yeah.
  • It takes more than that: 1.  No carrier exlusivity 2.  microSD 3.  Priced at $299  
  • That would be perfect +730
  • NFC Qi Some waterproof capability Since we're stating some of our wishes, good list by the way.  The early sales of the 635 with promotions hopefully betray a demand for independent purchases, speaking to point one.
  • Yes please. 730 would be perfect!
  • Yes.But in countries like India where we don't have Exclusive shit,Contracts we too have wait if any Lumia is Exclusively for some carrier which shouldn't be the thing which makes us to choose another phone coz who knows when the contract will end & will be available for us some Lumia's didn't even made to India such as L928,822,Icon(L930 it is coming but had to wait too long).Not yet available & it doesn't makes sense to buy 1.No micro sd support. 2.No dual sim config in High end Lumias yet 3.No glance screen 4.Makes no sense to buy.
  • Totally agree with your comments.
  • Snapdragon 400 should be the minimum standards in Wp & Snap600 for mid tier phones clocked at 1.7ghz quad core processor it would be cool & 1gb ram minimum to low end as well to mid tier wp's.
  • Looking forward to this one
  • I dont like onscreen buttons .!! :/ of this had a similiar design to 720 with upgraded specs. I would have loved to spend bucks on it .!,
  • But btw if it would be having some Carrier exclusivity we too would have to wait till the contract to end which Sucks.Hope it is a successor not like L530 which is a big Fail & downgraded Lumia for name sake.
  • But what standard color starts with the letter D?
  • Denim?
  • Got that right!!
  • Dark Blue
  • Dark Daredevil 
  • I don't think there is one!!
  • Dandelion, Daffodil, Dark Green, Dark red, dark blue, etc, dusk, dorado, denim, dun (yes that's actually a color),
  • I like dusk...
  • These^
  • Lumia Dun hahaha
  • You googled. No way you knew that off the top of your head.
  • Maybe he Bing-ed...
  • I'd upvote you, but we don't seem to have those yet :)
  • Maybe dark cherry would be cool
  • Dirty blonde, dookie brown, dark chocolate, denim, desert sand...many possible names lol
  • Lumia Dirty Blonde hahaha
  • U naughty naughty boy.Xd
  • Lumia Dew?
  • The word 'Daquiri' has a nice ring to it. Although dubious if it could count as a colour :P The cocktail tends to be red though :3
  • Lumia deer
  • Y dark blue dark green etc?? Y would it jus "dark"? We can call it as "dark update" :-p
  • Is this star wars? Welcome to the dark side
  • Dirty dishweter? Dishwater Blonde?
  • I think Nokia will release that update next year when they use the way they everytime use
  • It's update 2 I guess
  • It is update 1.Because update 2 is not even pushed to developers for testing so how can Nokia make their firmware so early.
  • How its not called cyan , + its starts with D which is the forth letter in alphabet
  • Cyan firmware is for wp8.1 & D(whatever) is for the wp8.1 Update 1.
  • Steven Elop had a Lumia 730 , 830 two months ago, so u can expect that the update 2 is out for them
  • I don't think so it has Wp8.1 update 2 because Even Microsoft hasn't yet ready to push it to Developers Preview for checking bugs. 1.Nokia had its firmware names Wp8 gdr2(Amber) wp8 gdr3(Black) wp8.1 (cyan) so the upcoming wp8.1 gdr will be (d something) 2.It has gdr1 update because Nokia hasn't given their firmware of wp8.1 first update aka gdr1.Nokia will be showcasing their additional features coming in their gdr1 firmware update launching soon with L730 & L830 just like they did with L1520's event which showcased Lumia BLACK Firmware. HOPE U Understand.
  • There's no reason it couldn't come with an official Update 1. Black came with GDR3.
  • Its clearly update 1 as Microsoft is working on it too.There's no chance of this Update to be the Update3.The update will come this year & maybe this phone would be launched in Nokia's own style.I mean they would unveil the Lumia & have people a look to their enhancements on Wp8.1 update 1.
  • But I want yellow one... Finally an update for my sexy 720
  • The 830 is much better
  • +620 i want the oreo black on the back 
  • Agreed that aluminium body with 5 inch screen and 13 mp camera
  • If you buy a phone in the same line as the other it's not an upgrade.
  • If the phone has updated specs the yes it is......
  • Umm. Yes it is you spanner!
  • He said update, not upgrade.
  • Yellow for too.
  • Interesting model. Would like to see if there is a camera button
  • It doesn't appear to have any at all.
  • I can see the volume control only
  • It's covered by his hand
  • Maybe I dunno why they create the WRONG hype ;P
  • My next phone all the way.
  • Debian red seems to be update 2 , good phone btw ;)
  • No update one. 8.1 is cyan bundle with lumia firmware. So update ome is...?
  • Idk
  • So sad about a real successor of NL620, unlike that 630... I'm tempted to wait for this 730, but 4.7 inches are too much for what I intend to carry around. We'll see in the future
  • It's excellent. Man ! Hope it has 720P screen resolution. Or the new 540 x 960
  • 540x960 would look pretty bad on a 4.7" screen.
  • Same here.  It's annoying that all new phones seem to be going to large display sizes.  Only the low end phones have 4 - 4.5" inch screens.  I want a phone that is compact, but still has reasonable quality.   However, I notice that this phone has virtual buttons instead of dedicated capicitive buttons.  If the extra screen takes the place of the space that would normally have capacitive buttons, then the 4.7" screen may not make the phone any larger than a ~4.3" phone.
  • That's what she said
  • Lol. Nice.
  • 4.7 on my Titan wasa nice size, and I really didn't notice the difference much with the 4.5 on my 920.   However, when back home, I had a look at the "930" (actual Icon with Verizon), and I will stand by my feeling that 5" is the sweet spot for larger phones. I am torn between the perfect size (930) and expandable storage (1520 - too damned big! LOL)
  • Haha. 5" is the sweetest spot but L929(Icon) L930(International Icon) both had no Expansible Storage option & Glance screen Man wtf.Nokia messed up.
  • The Lumia Icon/929/930 and the Lumin 928 are almost the same phyiscal size, only slightly bigger than the 928.  However, the screen size is 5" as compared to the 4.5" screen on the 928.  So wait to see if they are able to do the same with this phone, getting a bigger screen without making the phone itself that might bigger.  It may only be slightly larger than the 720.
  • Debian not have any mean?
  • It is a flavor of Linux/UNIX. As far as I know it doesn't mean anything else.
  • Debian Red is an actuall color..
  • Debian Red is the red used by the Debian logo.  It's named after Debian the linux distro, not the other way around.
  • It's named after the project founder, Ian, and his wife, Deb.  Seriously.
  • I'm not getting a phone with those virtual buttons, it just seems like I would always accidentally touch them. I also just like the look of the buttons on my 520 more. Though I need a new phone maybe mid- range now.
  • Count me in. Seems I will have to jump straight to 830 or above from the low end just because MS sees capacitive and camera buttons as a high end feature.
  • 830 I the best designed phone ever !!
