Why no 1080p vid and 5mp 3d? - HTC EVO 3D

So..i want a answer. Surely some developer or a teardown must have got results.
I mean if we really have dual 5mp cameras...then why the hell cant they shoot both at full 5mp power at desame time?
Is the second camera simply 2mp and are the specs lies?
Is the hardware not able to shoot 1080p for some reason?
Especially for the evo 3d's running at 1,5 - 1,8ghz...
I would like a developer or someone who knows about this stuff...why all 3d phones cant simply shoot 3d pics in their native resolution..and why 3d video is not 1080p...and 2d is not 1080p...
Hopefully we can get a clear answer this weekend?

Stock SD card probably couldn't handle the continuous throughput not to mention the sensor would have trouble delivering a reasonable frame rate (definitely not 30fps...not even close) in all but absolutely perfect lighting...and I have my doubts about that even being possible. The sensor and the SoC are not only capable of it, they are designed to do it (It's in the specs of the MSM8660 and 1080p is a hair over 2mp)....however the system, as a whole integrated device, is likely not capable of doing it in a way that wouldn't be embarrasing. 720p already sucks enough as it is...if they can't get that right I wouldn't even want to see their attempt at 1080p.
I may very well be wrong...in fact I hope I am, but I doubt it.
EDIT: Regarding the 5mp 3D, however, I am confidant that is very possible....so long as the cameras are individually addressable. I think the choice of 2.5mp for 3D was a practical one. Since it uses SBS-half (Side by side - half resolution) the image is stored in a 5mp file, 2.5mp for the left and 2.5mp for the right. Though I think there may be a performance penalty when dealing with a 10mp SBS-half image file (5mp for the left, 5mp for the right). It would be idiotic for them to throw in a 2mp sensor just for 3D....it would likely be more expensive to source another part instead of just double the quantity of the same one...again, I may very well be wrong about that but I doubt it.

I hope you are right about the second part...
2.5mp + 2.5mp doesnt make a 5mp photo. The cameras both take desame picture but with different focus, if i remember correctly.
Also i find it stopid that browsing pictures makes the 3d effect kick in after a secomd...not immediatly..

2.5mp+2.5mp side-by-side doesn't make a 5mp quality photo...in 3D or otherwise, but it is in fact a 5mp file. There are 5 million pixels in the file and there ain't no way around that...Half of those get spent on depth. Besides we can only view them at 480x270, so, the only benefit you would get aside from a higher quality 'master' copy wouldn't be realized unless you viewed it on something with a higher resolution, like a 3D TV that does SBS-full...but even then you are barely cracking 2mp of resolution.
...either way I know I would feel better knowing my 3D pictures were at least moderately future-proof....and don't even get me going on the "720p" 3D video--if you haven't figured it out yet don't try, it'll just upset you.

1) HTC EVO 3D will isolate twin cameras to produce the firsts 180 degree panoramic photo at 5mp resolution. (Option will be in sense UI)
2) HTC EVO will produce the first ever 10mp photo on cell phone by using what is called paralax photo capture (each camera will capture an image and over lay it to produce 10mp photo) (Once again tap on 10mp photo)
3) Light sampling will be independent of each CMOS sensor to produce what will be close to night vision capture (Night Owl)
4) Camera will have a Sport mode, the 5mp camera's will function in tandem, but alternate. Each camera will burst alternately and provide crystal clear photography on high speed action events.

To be upfront burst sport mode will only work in 2d mode for obvious reasons, because the two cameras are sharing the [email protected]

Granted that this garbage above was initially spewed by some poser who pretended to work for HTC/Sprint... some of the ideas are genuinely clever. I've added them to my own in the list below of what could possibly result from the dual-camera setup. Tell me what you think!
Greater detail. Using both cameras at once to capture two 5mp images and "overlaying" them is interesting. Maybe adaptively "adding" the details in one to the other? Maybe using some kind of "interlaced" trick, or maybe the tilt is a bit different so both can take pictures of 2 different [but adjacent] visual fields for "instant panorama"?
Greater depth of focus. Each camera can shoot simultaneously with a different focus, and the result easily combined into a picture with incredible depth of focus.
Sport mode (shutter speed enhancement) seems like a wonderful idea. Both cameras fire, one a few ms after the other, and the result motion compensated. The perspective difference may also be used to identify and correct for motion blur. As an instantaneous "anti-shake" this would work wonderfully, too. All in all, this would allow the camera to capture faster motion with less blur!
Double speed burst-mode. Burst mode could theoretically be twice as fast, since the other lens could fire during the recovery time of the first.
Dark mode / night owl / de-graining. A fantastic idea would be to use both cameras to capture a picture simultaneously at high ISO and use a simple perspective-corrected denoiser to drastically improve quality of night scenes, which suffer most from grain issues. Each picture is bound to have a different amount of "random noise" or "camera noise" from the two cameras, and after perspective correction (and/or motion compensation if one fires after the other), the randomness is detected and removed from the combined image.
HDR (High Dynamic Range) can be achieved with no additional delay by having both cameras snap at different exposures and combining the result, solving the "low dynamic range" problem with the Sensation and other phone cameras.
Apply all of these to video. If both capture video simultaneously, there could be some benefit in 2D mode -- timestamps of the recorded frames can allow them to be combined to produce a single video of higher effective average framerate -- again, with some simple HW perspective correction filter. It could also drastically improve the quality of night video in the same way as the above "night mode" camera use with the additional potential advantage of temporal denoising, resulting in the cleanest night video you can imagine. Not to mention the first ever high dynamic range (HDR) video on a mobile device.

It's obvious these aren't going to be included in the official ROM, but I'm sure there can be "an app for [some of] that" provided the API of both cameras are exposed. Exciting prospect, is it not? The only one of these that seems a bit hard to chew is of course the 10mp nonsense. At most the combined detail would just produce a "very nice" 5mp shot.

I don't quite get it.
Anyway, I also think it would be neat to use the two cameras to offset an alarming trend in phone cameras -- low dynamic range. Both can fire simultaneously at different exposure settings, and combined into one HDR image.
I think what they mean by the horses, is that this is kinda crap.
It's already been known that when taking 2D pictures, it uses the top-most camera only. It uses only one. Only in 3D does it use both cameras.

Ah... gotcha. More than "kinda" crap, it's genuine crock, yes.
But I'm saying the ideas are so good -- the potential is there. With a system update from HTC, these can be almost trivially enabled. Otherwise, if the API for camera 2 is accessible, an app can be created to provide the remaining functionality.

Yea, forget all the crap that everyone spews. Anything is possible, with the devs here on xda. As Mlin said, I'm sure there will some dev or a team of devs that will develop an app to take FULL advantage of the dual cams. Granted, I'm sure there will be plents of limits on what the cams are capable of, however, I'm sure that those limits will be pushed and that we'll eventually get max potential out of the cams.
Did anyone think we'd ever get Full HDMI mirroring working on the OG Evo?

Good point. But hopefully the actual camera hardware on the 3D will be quite nice, so more will be able to be done with it. Hopefully. I would think that there could be more potential to be unlocked in the cams, but who knows.
Anyone know which devs have said they will be coming over to the 3d to develop yet?

You get an "A" for thinking so far outside the conventional box, but unfortunately I don't see any real possibility of any of that ever coming to pass, for one inescapable reason: the two cameras aren't shooting from the same location. Every concept you describe requires that both cameras see the same thing, and they don't, for the simple fact that the pictures they take are from two different physical locations.

Fixed-point location adjustment is trivial and can be performed in software/hardware with minimal effort (even perspective/angle adjustment via convolution-deconvolution of 3d signal matrix). Also, even if they weren't shooting from precisely the same location or perspective, the motion-compensated technique can be applied even to different frames in a video (making 'night shots' more doable), since the temporal element is the most tricky. If both cameras fire simultaneously, tracking synthetic "motion vectors" is utterly trivial.
Even if a developer was lazy and didn't want to implement perspective correction, a subset of the two pictures near the center (where they overlap) can be used for all of the rough work, and a simple guassian averaging function can perform the spreading (or simulated annealing) from that point.
No, location is certainly not a problem -- and even perspective is fairly easy to (accurately) account for via straightforward signal processing algorithms both in hardware and software.

Dual cameras or single camera?

So am I the only person who would prefer having a single, high quality 8mp (1080p recording) camera as opposed to the dual 3D cameras? I already pre-ordered the EVO 3D, so no matter what I'm excited about it, but personally I could have done without the 3D and instead would prefer a better quality single camera. I might switch over to the EVO 4G+ if it ever comes to Sprint because it seems like exactly what I'm looking for.
Either way, can't wait to get my 3D! I've loved my EVO 4G since I've owned it but I've always hated the crappy Adreno200 GPU
The lens and camera hardware are so small on these phones that 8mp vs 5mp has nothing to do with quality. The iPhone 4's camera is 5MP and takes better pictures than the EVO 4G's 8MP camera. From what I've seen, the EVO 3D is better than the EVO 4G in that department as well.
I HIGHLY doubt Sprint will get that phone. And if I had a choice, I wouldve gotten the 4G+.
the photos from the E3D are on par if not better than the EVO 4G's pictures
I would rather have one camera with a bigger sensor, that being said the 3D takes just as good if not better 2D pics than my Evo 4G before it. And I don't see what's wrong with the reviewers it isn't hard to take a good 3D photo on the phone either.
i wanted a larger 8mp or higher camera also but after using the 5mp with the E3D im happy to have a decent camera on hand when i need it, if i need excellent pictures ill take my Nikon
Yeah I love my Nikon also but I just hate lugging that thing around LOL! Hopefully the E3D camera is decent and more importantly FAST! Like, I want to be able to take a quick snapshot and have the picture come out decently. I don't want to have to buy an LX5 or an S95. My idea of a good camera phone is the iPhone 4, just so you have a point of reference.
How fast/responsive is the E3D camera? Gosh I can't wait, just a few more days!
I personally love the 3D camera. I mean, do you really need to take Cinema quality video with a cellphone, no. I think it will be a pretty fun camera to have and interested to see what else this phone will do once more 3D content is available.
So far I have noticed strange behavior when taking pics... when I hit the shutter in low-light situations, the picture on screen when the shutter sounds fires off is not the same as the one saved... it's a significant delay and subjects have moved, etc. Not sure why the camera 'blinks' or whatever... reminds me of the iPhone.
only problem im seeing is the pictures that we see are saving INVERTED not on all but some pics and i don't know why
To be honest, I really don't care about the camera on the back. I post all my pictures worth saving on Facebook, and that resizes the crap outta them, making even an awesome camera look meh.
As for the people saying they'd rather have the Evo 4G+...
Evo 4G+
Pro: Bigger Camera
Con: Doesn't exist yet.
You don't have that choice, Sorry.

Here is why that happens. In low light situations, the shutter needs to stay open longer to allow more light to hit the sensor and "burn" the pic. So the shutter sounds when the digital "shutter opens", but if it stays open for anything more than 1/60 of a sec (which in low light this camera shoots at about 1/30), there is going to be a significant delay and you will end up with a different shot that you thought you would get. In low light - make sure the subject stays still until the preview pic comes up - or use the flash...

EVO Questions (Sense, 3D, AutoZoom)

I just had a few questions about my new Evo 3D... I've been looking on the forum. but haven't found anything... So I thought I'd Ask..
Isn't Sense 3.0 supposed to support landscape mode on the UI? (is there an option to enable this? - 2.1, I think Supported this on my OG E4G.
Is the 3D camera/video supposed to constantly auto focus over and over? i can see maybe it needs to due to the 2 cameras. but it kinda gets annoying, when trying to take a pic.. haha.
Why does the 3D only work in Landscape mode? .. like if I take a pic in 3D, it will only take the pic if I have the phone tilted to landscape. which is crazy to me. Many shots look better from the portrait angle. which is refuses to take pictures that way. my thinking is. if its 3D. wouldn't the orientation not matter? and worse case scenario if it did. so I have a pic that you view sideways. But i'd still have my better angle picture, right?
Other than those issues, I've loved the phone. the 3D is better then I thought it'd be. a lil weird/different to get used to. I love the speed, it restored my texts from my previous phone, and deleting threads took seconds, not hours. that was really nice.
I believe that the screen has to be looked at horizontally because of the 3d technology the screen uses? Kind of like certain types of polarized 3d glasses. The 3d effect isn't the same when you look at the screen when it is vertical.

I'm only 99% sure of this one. I believe the 3D only works in landscape mode because the the cameras need to be in a horizontal fashion to take a 3D picture. The camera's have to be side by side instead of top and bottom.
I suppose if you took the picture in portrait, then were able to turn your phone horizontally without rotating the screen that you'd be able to view a portrait 3D picture, but then your picture would be sideways.
Whatever the case, the cameras need to be side by side. That is the nature of stereoscopic images. Ever seen a Magic Eye picture? Imagine trying to see the hidden image in portrait. Not possible.

I do like the 3D, but I really only like it when watching movies in 3D (i.e. Green Hornet) and when watching certain YouTube 3D videos. The videos made with higher end 3D camera equipment look really cool. The ones shot from Evo 3D don't look as good to me.
look at the layout of the lenses. If you tilt it on it's side it would be like tilting your head to the side. not to mention the 3D is more a fun gimmick than a primary use feature.
the only way they could take a 3D portrait picture would be if the lenses rotated to keep them horizontal.
the UI does not rotate does not do landscape, the one you were using was a port of either the desire z or shift that allows it due to the hardware keyboard.
i am sure it will be one of the first ports once we get root.
thank you for the replies guys.. i knew it'd be a good idea to ask here..
I did have another question.. I want to put thousands of pictures on my evo. (friends, pets, guitars, live concert pics, funny pics, illusions, etc) .. years ago, when I had my Palm Centro. I found, I was able to compress the images. and keep fairly good quality for that screen.. i was able to drop 2meg pics down to like 37k in filesize .. i was able to fit a couple thousand pictures on the sd card there, and it was somethinge like 300 megs.. it was nice.. i tried to copy those to my Ipod classic. and i guess the Ipod, did'nt like that.. as it re-created the pics bigger. but i can only assume to better fit that screen. so I was bummed out..
anyhow.. I would like to put many pics on my Evo 3D like that, but cut size. though keep relatively decent quality. if i open it on my evo, i'd like it to be full screen and clear... but compressed down from the 900k-2megs that the camera, or even the Evo 4G did..
Does anyone have any recommendations on either what resolution/quality to convert the pics too? / a program to do it? / advice?
I found a tutorial on converting video to work best on the evo. and it says: Set the EVO 3D Width and Height (the EVO 3D supports a maximum of 960 x 540 pixels) .. so that makes sense for video.. but not for pictures.. - but it was this tutorial that got me thinking.. (i also tried last year to find info on optimal pic size for the Evo 4G, and could'nt find anything and gave up looking)

Ok, for the photo compression question (if you still have it) I can point you in the right direction, but don't exactly have a solid solution for you. I use Photoshop and that has a feature to compress images. If you have that, great. But it's not worth getting just to compress photos. But the tool is "optimize for web." This strips the photo of all extra bits that won't be necessary. You'd want to be close to that 960x540 resolution too. Maybe try searching for photo optimizing software, possibly something geared to preparing photos for a website. If you find something and it asks how heavily to compress a jpeg on a number scale, usually 8 is a good starting point.

I found, I was able to compress the images. and keep fairly good quality for that screen.. i was able to drop 2meg pics down to like 37k in filesize .. i was able to fit a couple thousand pictures on the sd card there, and it was somethinge like 300 megs.. it was nice.. i tried to copy those to my Ipod classic. and i guess the Ipod, did'nt like that.. as it re-created the pics bigger. but i can only assume to better fit that screen. so I was bummed out..
anyhow.. I would like to put many pics on my Evo 3D like that, but cut size. though keep relatively decent quality. if i open it on my evo, i'd like it to be full screen and clear... but compressed down from the 900k-2megs that the camera, or even the Evo 4G did..
Does anyone have any recommendations on either what resolution/quality to convert the pics too? / a program to do it? / advice?
I found a tutorial on converting video to work best on the evo. and it says: Set the EVO 3D Width and Height (the EVO 3D supports a maximum of 960 x 540 pixels) .. so that makes sense for video.. but not for pictures.. - but it was this tutorial that got me thinking.. (i also tried last year to find info on optimal pic size for the Evo 4G, and could'nt find anything and gave up looking)

If I were you, I'd invest in a 32 GB SD card if you want optimal quality photos. As you probably already know, the more you compress a photo's file size, the more the quality of the picture degrades, especially with the JPEG file format. The JPEG file format, which is used on all the cameras I've played with so far, can compress an image down to a really low file size, but at the same time the picture quality degrades. The JPEG format also suffers from generation loss, meaning every time you decode and encode an image into the JPEG format, you lose quality. Personally, I prefer the PNG format over other formats since it uses lossless compression, but I don't think the EVO 3D's camera has an option to save in that format. The downside of the PNG format is that the file sizes are still larger than the JPEG format, but it's significantly smaller than the RAW format.
But then again, you're using a phone camera. If you were using a professional or high end amateur camera, I'm pretty sure things would be different. Basically what I want you to take from this is to try to avoid compressing/decompressing JPEG images often. It degrades the picture quality. I only wish the EVO 3D could save images in PNG format since it uses lossless compression.

[Q] Slow motion video recording?

I would really love being able to do some slow-mo videos with my SGS2, any way to do so?
The camera simply isn't built for that kind of use. You could do it, if there were software, but the framerate would be atrocious.
Here's an app for playing back videos in slow motion...

Probably the best and only solution. The camera was only built for up to 30fps I believe. If you know how slow motion cameras work (very high frame rate), you should see how this is a problem .
I'm bringing this thread back to life to save cluttering the board up with yet another similar one. I've been looking for an app to do the same thing and have, like other searching, not found anything to suit.
The reason I'm still chasing it down is that I had the Samsung Jet before my SGSII and even given it's age and utter lack of power compared it had the feature to be able to record video at high speed so that when played back it would be very good quality slow motion (25% speed if my memory recalls correctly).
Now, if that phone could do it so long ago with little native power and a poor camera then surely the SGSII could do something like that at the very least, even if the max video size had to be dropped to 640x480 or similar to keep the framerate more locked in?
Want that too!
Can somebody pls answer this question.. Is 30fps hardware limitation?? Really??
I once had Samsung OmniaHD with 8Mpix camera, probably not much different from any other, and 320x240 resolution it was able to capture 120fps..
How can it be a limitation of hardware? Isn't it possible to write an app that would capture even 240fps at lower resolutions?

I'm searching for this since a year from now, I think the problem remains in the drivers and not in android SO, there is one or two android phones that support is, but I dont know how exactly, if I dont misstake samsung galaxy note 2 and one motorola has slowmotion, I belive that they build a driver to use de camera as fast as possible, on other devices I think that is not possible unless some can build such driver, and that probably will need to do in some native assembler code of each device cpu and irqs, unless the company release that driver
the functions of android to get frames from camera are very limited to useless stuff and pre-set formats and fps
I dont know whats about with android 3.1+ or 4, maybe thats SO has this functionality natively
get fast fps from a ccd camera is not a MP issue nor too much CPU requeriments nor related to amount of RAM
with a windows mobile 6.1 device such samsung omnia i900, that has a 625mhz CPU and a 5MP camera you can record 120fps in 320x240, the camera of this phone has ISO 800 (it doesn't mean 800fps, but means that it can get a very tiny little power signal from sensor in a very short amount of time) but android cameras discard this features and incorporates functions very limited and related to normal users

I don't think you understand the concept of cameras well. The hardware determines whether it is 30 or 60fps and not the software.
For slow motion, the highest a consumer (or affordable) camera does is 1080p at 60fps.
There are cameras like phantom hd that do well over 1k fps but they cost 100k

Not completely accurate.
For a consumer camera, the highest framerate at 1080p might be 60fps like you say, but some low cost consumer sensors can do high fps at lower rez. My $100 Canon Elph 100HS from 2011 will do 640x480 at 120fps or (I think) 320x240 at 240fps. I've used the 480p120 option and it came out very nice for sports use, especially for reviewing batting swings with players. The sensor tech for fairly high frame rate at decent (480p) rez is not limited to >$1000 cameras, leading me to believe it's probably more software related. I don't know enough about the sensor in the GSII though.
*Edit*
Apparently the Galaxy S II uses one of two identically spec'd (according to Anandtech) sensors from either Samsung or Sony. The Sony IMX105 specs are here. According to that page the sensor should be capable of 120fps at 1/8 sub sampling. I am not entirely sure what they mean by 1/8 sub sampling, but I would assume that it means using 1/8 of the effective pixel count or about 1M pixels. If all that is true, then the hardware should be capable of 640x480 at 120fps. Some assumptions there, though.

HTC one mini 2 with 13MP camera.... WTF????

Thanks HTC for bring a bigger mp camera to a phone that's suppose to be the little brother of the m8.........
http://mobile.theverge.com/2014/5/...tes-the-companys-flagship-phone-in-a-trimmed
...because we're ALWAYS complaining about the MP on our camera when we just upload the photos to instagram and fb..
You can't say that for ALL users. A lot of people don't need a expensive camera to take pics. Especially if you want to use that pic past Facebook etc. All I'm saying is instead of adding a second camera. HTC could have added more to the m8 to help keep it from being the same camera with a second camera. End of the day 4mp camera is a 4mp camera
When I want to use my pics past loading onto social apps. I use my note 3. But if I want to use this pic to upload then yes either my m8 or note 3 will do the job just fine

I'll agree that what smartphone camera is "better" depends on how you in particular use the camera. But just because a camera has more MP, does not make it "better" either. We'll have to wait and see if the camera on the One Mini 2 actually yields better quality images than the M8.
Unless you are blowing up or cropping photos a lot, 13 MP is too much and a joke for a camera phone. High MP smartphone cameras really struggle in low light. And unless you are taking pictures outdoors in broad daylight, its often low light.
I'll agree that HTC probably should not have opted for the dual camera on the M8. Kinda cool at times, but also pretty gimmicky. The money probably would have been better spent improving image quality on the single rear camera (even if not to increase the MP).
It's kinda a slap in the face to a certain degree. Here is the new m8 with the same camera with a secondary camera which is mostly gimmicky while nice at the same time. Then they decide to make the new HTC one mini from a 5 mp camera to a 13MP camera...........
Now will it have better pics? Probably not or probably so. For most people it don't matter, but after being in retail when trying to sell a customer the one the camera is its downside cause on PAPER the 4mp camera doesn't sound good at all compared to the other smartphones out in the market. People will buy the mini 2 because of it has higher mp count than the m8. While the m8 blows the mini in other specs that 13MP camera looks a lot better to somebody who doesn't care to have the latest and greatest specs.
While a higher mp count doesn't make a camera phone any better yes, but why bring the same thing to the table for your flagship but have a mid range phone with a better spec camera on paper WHEN it comes to mp count. .

Unfortunately, Average Joe is always going to fall for that marketing gimmick of chasing big numbers, without having any real understanding of what they mean. How many times have you seen someone with a fancy, big screen 1080p TV; and the owner just has a standard definition program on it; and not even in the right aspect ratio (so the picture is all stretched out to fill the screen). That kinda crap drives me crazy!
I for one applaud HTC for turning their nose up at the megapixel arms race. Its gotten absurd. I mean seriously, do we really need a smartphone with a 41 MP camera? Of course not (I understand its actually a really good camera, but not because its 41 MP).

That is a really good point. Why push a certain marketing strategy (and one that particularly bucks the trend) for one device, then do nearly the exact opposite for another device.
In any case, I don't think that the Mini 2 will really compete directly with the M8. Price point alone, even the Average Joe Blow is going to know its a flagship versus a "budget" phone. Don't know about the One Mini in particular, but for the most part, any HTC phone aside from the "flagship" tends to sell in extremely low numbers. At least here in the US (don't know about other regions).

The same reason we need 4k Tv's and 2k screen on smartphones. To keep making them money lol! Exactly why say your not going to follow the trend but all your other phones are right in the trend? Lol but HTC could have tried a little harder for the m8 speaking of the camera of course. The phone is rock solid but don't have these commercials making fun of these mp trends and being different when your other devices join right in with today's trends.

Some of my favorite shots have come from the camera on my M8. In terms of higher quality, I'm actually looking at the Sony G Lens, since it is supposed to take really nice shots, and is $200 at my local best buy.
Some people such as my self want a phone with camera and some prefer cameras that can be used as a phone.

If I want to use my pics for something worthwhile, I use my Canon EOS.. otherwise I use a crappy phone camera.
lets all cut the crap. the camera is nice on the M8 and i do agree. to a certain degree. mega pixels don't make the camera. but it sucks for details when blowing up pictures or zooming we dont need 20 mp. but i think we should have something alittle higher

reviews for the one mini 2 have started surfacing. in ideal conditions it is resolving a lot more detail, by a huge margin. but anything other than ideal and the m8 takes it.
i think the 2.0 pixel size is great and all, but i think we couldve benefited a lot for 1.8 sized pixels and an extra megapixel. that configuration shouldn't lead to a large camera hump.
i'm happy with what i got either way, i do miss the old OIS from my old m7. but whatever, the m8 has proven to be a capable shooter. and my nx300 is always on stand by in case i need a real camera
Any advice on rooting the Mini 2. I receive it tomorrow from carphone warehouse (379sterling.) Has the original Mini gained from official CM11 support thus far?
Any insight on how to root my forthcoming mini 2 and gaining cwm and porting roms would be greatly appreciated.
Does anyone know what phone o could potentially port from for the Mini 2.
How difficult to root and install a custom cwm recovery?
Hello community!
I have just bought the new HTC One Mini 2, it is locked with EE network. It looks like I am unable to get the unlock code anywhere. Do you have any suggestion or advice?
Wrong board
what sucks is having a super light sensitive camera.. while living in Florida. It's always bright unless you paint your windows black.
So what if it has a camera with higher MPs. That doesn't make it a better phone than m8. Unless HTC comes up with a device having the same internals as the m8 but a better camera resolution, I don't see what is there to fuss about.

I'm not so sure that having a more sensitive sensor (while better for low light situations) necessarily means that there will be too much light in bright situations. The camera controls the sensitivity (ISO based on the old "film speed" terminology) as well as the aperture (f-stop). It might be that the automatic exposure that the camera is trying to achieve (balance between ISO, aperture and shutter time) is too bright for your local conditions. In which case, you can manually lower the exposure by tapping the 3-top menu button in the camera app, tap EV and lower the exposure value.

I've messed with all the settings. I appreciate the feedback though...
Unfortunately, if i have any picture with a bright spot from the sun the whole picture gets washed out. Full indoor is fine and full outdoor is fine. But daytime pictures indoors with sun coming in the window- washed out. Granted- if i still lived in Philly (or most parts of the country) i doubt it would be an issue.

Any camera will have issues if there are areas in the frame which are very bright, or spotty lighting (mix of bright and darker spots). Or does it seem worse with the phone? Often forcing the focus to a different spot by tapping the screen helps a lot.
