[T-Mobile Galaxy Note 4 General] Ry&Owley:
I considered a similar situation when trying to use my phone as a decibel meter to measure how loud my car exhaust was. I was getting complaints from one of my neighbors about my wrx being too noisy so I ended up measuring it with my phone. It didn't work because the microphone on these phones is chosen and calibrated for its sensitivity to the noise a regular human voice makes when the phone is reasonably close to a human mouth. Using the phone in a "live" environment or somewhere there is a ton of background noise or amplified vocals or other sources of noise outside of its specs will likely interfere with your recordings. You'd need to test it in a more scientific way to narrow down the problem try isolating if all recordings are ruined or just really loud ones or if even the choppiness could be caused by processing power and too many background apps or something.
[T-Mobile Galaxy Note 4 General] Ry&Owley:
Argh I got confused an reinstalled the note 4 optics. The note4 optics work great in the note 4 the s6 optics still unfocused =(

I have a new idea when my new s6 module gets here I'm just going to bend the ribbon cable and plug it into the motherboard at some weird angle and see if it can focus. If it can't then I know it's a software issue or a hardware issue with the board itself which is something I'll never be able to fix.
[T-Mobile Galaxy Note 4 General] Temetka:
Nice work detailing everything. I've been extremely happy with the camera in my Note 4 and tbh, never even thought about this.

I'm a pretty hardcore geek and have done stuff like this with laptops, but a $700 phone? Nope. You get major props for even attempting it.

I hope your idea with the next module works out.
[T-Mobile Galaxy Note 4 General] xanmato:
Unfortunately your issue is software related. The IMX 240 uses phase detection for focusing. The sensor takes image samples from different areas of the sensor, and compares them to see how 'out of phase' they are. Once determined, it uses a calculated correction to align the lens elements and thus achieve focus, and then finishes it off with a small contrast detection adjustment.

What's happening is that you have changed the lens elements specifications, as the S6 version has a f/1.9 aperture configuration, so the elements are different sizes. The phase calculation formula no longer works, the contrast detection is too far out of parameters, and the camera restarts focus/fails.

Your devised test will confirm if the phase calculations are done on the sensor board, or on the phone. I am guessing its on the sensor board, and a new s6 module just hanging there should focus. That also means your swap idea will never work without the s6 board. :(
[T-Mobile Galaxy Note 4 General] Ry&Owley:
[MENTION=951327]xanmato[/MENTION] Thanks so much, this would have been hard for me to diagnose by myself. Time to figure out the connector type so I can figure out an extension cord. You don't happen to know what it is just from seeing it do you? All I have is that previously referenced article but he seemed to know how to classify the connector from looking at it.

https://zavax.wordpress.com/2012/04/29/extend-the-3d-stereo-camera-module-of-lg-thrill-phone-p925/
[T-Mobile Galaxy Note 4 General] xanmato:
I don't know the connector, but your best bet would be to inquire with a skilled out of warranty repair shop, or a sony service center tech. Though I am guessing the connector will not be so easily acquired. Like the article, you could use new connectors and cables, but you have to be some sort of wizard to be able to solder those pads.

Another angle: Are the Note 4 and S6 optics housings the same size? If they are, I can't really see why the S6 sensor board is bigger than the Note 4's other than for packaging reasons. There is a good chance you could just trim the S6 board down a little without hitting anything vital, just enough to squeeze it into the Note 4.
[T-Mobile Galaxy Note 4 General] Ry&Owley:
[MENTION=951327]xanmato[/MENTION] I thought of trimming the board down, unfortunately the position of the optics themselves is the issue, I'd have to trim the motherboard to get it to fit in the cutout or I'd be dremeling the electromagnetic stage. It's just a layout issue where the actual optical portion needs to be shifted up slightly. A tech at digikey is going to take a shot at identifying the connector for me based on some pitch measurements taken with a digital caliper hopefully they can point me in the right direction.
[T-Mobile Galaxy Note 4 General] Ry&Owley:
S6/Note4 Connector

Thanks to Digikey,

Here is some more info about the connector

Digikey got back to me with this info:

These were a bit different from what I was expecting. These would be a mezzanine FPC connector. We may have the connector portion but the cables would be more custom (flexible printed circuit).

Description: 36 pos, 2 rows, receptacle center strip contact, pitch 0.016" (0.40mm)

Example of Similar part we carry - 670-2572-1-ND

Here's hoping it fits!

So, what I'm working on now is some sort of adapter board where on one side is the connector that receives the camera and other side receives the motherboard about 3 mm above the camera connector. Some sort of 32 pin through hole deal I guess? I've got plenty of room because I can mill out space for it from the aluminum subframe like I did for the sensor.
[T-Mobile Galaxy Note 4 General] Ry&Owley:
Chipworks has this badass teardown with sick high res photos, unfortunately they don't go into the connector I need to know about.

Here is an extremely technical drawing of my plan.
[T-Mobile Galaxy Note 4 General] jazzmachine:
L-O-L! The intensely skill dependent aspects of this undertaking is now entirely clear ;) :laugh:

Seriously though, I've been both following this post since you began it out of pure technical curiosity. What I've read this far has truly left me in awe - like another poster, I'm somewhat "into" DIY electronics modding (laptops, headphones, etc.) but this project and your work on it is seriously next level. I've just been wanting to send some

serious respect

your way, both for tackling this project in the first place as well as what you've achieved so far and your diligence to "solving" it :good:

Clearly this isn't a mod that will ever be suitable for the technically inexperienced or "faint-of-heart", but it's nonetheless fascinating and I'd really like to thank you for documenting the project on XDA!
[T-Mobile Galaxy Note 4 General] Ry&Owley:
Ok so the digikey connectors came and they don't fit but I'm thinking it might be a panasonic because they appear to designate their connectors with a 1 number 1 letter combo like this and the connectors say 5G and 5J. this is some photo off digikey. So now to find the right series from panasonic.

[MENTION=5057596]jazzmachine[/MENTION] thank you for your kind words :)

Ok here we go, hopefully one of these guys works, also wrote an email to panasonic asking if they could ID it.
[T-Mobile Galaxy Note 4 General] davwman:
If you get this working I would gladly pay you to set me up with one! Good luck! Keeping my fingers crossed
[T-Mobile Galaxy Note 4 General] xanmato:
I would advise caution to anyone who wants to attempt this mod if he ultimately becomes successful. The end payoff, or 'upgrade' is approximately 1/3rd of a stop, and that's it. The final image quality is going to be near identical to a regular Note 4 camera. The biggest differences in image quality from the Note 4 vs the S6 is from the image processing. So anyone undertaking this mod shouldn't expect S6 quality images.

Disassembling a Note 4 is not for the faint of heart, so you will have to decide if cracking open a $700 phone is worth the upgrade.

For everyone else, wait for camera API 2 support via Samsung or custom rom. You can also use a different camera app such as "Snap camera HDR", which allows you to bypass the Samsung noise reduction processing.
[T-Mobile Galaxy Note 4 General] Ry&Owley:
[MENTION=951327]xanmato[/MENTION] isn't the image processing taking place on the board? I thought that's why the focus was so suck.
[T-Mobile Galaxy Note 4 General] xanmato:
The onboard processors on the camera modules handle the OIS and PDAF/Focus calculations, basically the hardware based side of image processing. This is completely separate from software side of image processing (Noise reduction, EIS, etc). Though at this time I do not know if RAW to JPG conversion is done on the module or in software, as the IMX 240 appears to have some special tricks, such as realtime HDR - not bracketed, in images

and

video. Though realtime HDR has its own issue in the form of severely degrade image quality.

The Note 4 and S6 camera modules should RAW output near identical quality images, the S6 having the small 1/3 stop advantage due to its larger lens aperture. The S6 has better, newer software image processing, but since Samsung has not yet implemented Camera 2 api, we are at the mercy of their software processing and conversion of the image. If Samsung has any desire to maintain a smaller codebase, the Note 4 should receive the same or similar updates regarding image processing and quality.

If they do implement Camera 2 api (supposedly in the upcoming 5.1.1 update), apps can have direct access the the RAW sensor data. This should completely close the gap between the Note 4 and S6 in terms of image quality, minus the said 1/3 stop advantage of the S6 optics.

Though like I said earlier, some other camera apps can get to the base JPG data, before its been noise reduced. With proper post processing, you can get better images and video than the current S6 camera/app. It currently does have some drawbacks though, as it appears there is no way to access the realtime HDR mode at this time, from the apps I have tested.
[T-Mobile Galaxy Note 4 General] Ry&Owley:
Today I decided on my interface, I'm going to try to buy a custom ffc like the ones below.

http://www.alibaba.com/product-detail/Smart-Bes-Custom-double-sided-flexible_1101276556.html

Found the data sheet for what I suspect these connectors are, I won't know until one shows up from digikey

I used that sheet to come up with an idea for a homebrew pcb in eagle cad, it's my first time using it and it's not super user friendly. Also when I was trying to route all the "wires' I realized this might just be too damn small to make a pcb for this kind of thing, in the size I'm going for. The other dude did it, in the previous link but his board is about 1/4 the size of a phone.
[T-Mobile Galaxy Note 4 General] davwman:
I bought the app. How do I bypass the noise reduction or is it done automatically?
[T-Mobile Galaxy Note 4 General] xanmato:
For Snap Camera HDR, it should be automatic. Just in case though, in the menus, enable "show advanced settings" in the other menu, and then enable 'Samsung camera mode' and 'zero shutter lag' in the photo menu. Do not enable 'denoise', which essentially turns noise reduction back on. The app also lets you increase recording bitrate for videos as well, though an HDR video mode seems to be absent.

There are 2 easy ways to see if the noise reduction is turned off. First is look at the picture in the gallery. Due to its view resizing algorithm, pictures will have a distinct noticeable noise pattern. This goes away the instant you zoom in a little, it does not affect quality. Zooming in will also let you see the increased noise, especially color noise, but there is much more fine detail. The other way is to check the image info. Images from the stock camera app usually top out at around 6MB in the most demanding scenes, whereas I have gotten 15MB images out of Snap Camera. Some people may think these images are worse due to the amount of noise, but a proper image editing tool like lightroom can remove the color noise while keeping the grain and detail. Regular users may be better off staying with the stock app.

Also note, 3rd party camera apps cannot use the SD card for photo storage on a stock phone. You must be rooted and use the SD card fix for it to work.
[T-Mobile Galaxy Note 4 General] Ry&Owley:
[MENTION=951327]xanmato[/MENTION] do you have a link handy to that specific SD card fix?
[T-Mobile Galaxy Note 4 General] xanmato:
"SD card fix" on the play store should get you an app that will do the job. They say its for kitkat but technically it should work on lollipop as well as it's the same file.

I did the manual fix as its a 1 line edit and you don't need an app that may have suspicious permissions. All the apps are supposed to automate the manual method exactly, so any odd permissions makes me weary of giving it root access.

Manual fix: http://xdaforums.com/note-4/general/fix-external-sd-card-write-fix-t2904629

-Requires root

-Requires capable app (I use ES File Explorer, root explorer also works well)
[T-Mobile Galaxy Note 4 General] Ry&Owley:
Just to let everyone know about the status of this: I can't get a matching connector from anyone, I'm almost sure it's a panasonic, but they won't tell me which one and it's not available for sale to someone like me. So for now, this is as far as it goes. Maybe I'll check back into this at some point if and when more information or my sophistication with micro soldering improves enough to experiment at this size.
[T-Mobile Galaxy Note 4 General] atanderson05:
This was a good read. I was just googling randomness with my note 4 and stumbled across this. Years later it would be cool to see how the newer camera's can possibly fit and what other mods you can do with the phone. The phone isn't $700 anymore, you can easily find one for $100. Seeing as though it's the last of it's kind maybe it will give some of you all(and me to) more willingness to do more projects on it. Cheers!

Hello, I have a problem with my Xperia T, I can't even navigate the phone without it turning off in a matter of seconds! It will work for some time in airplane mode unless it heats up or using Bluetooth etc.

But the thing is it works fine with the charger plugged in!

Things I've tried in chronological order :

-Uninstalling all Apps

-Factory restore

-Disconnecting -> reconnecting battery

-Flashing ROM again - Flashtool

None of these seemed to have did anything as the problem still persists! Any help will be appreciated!

[Nexus 6 Q&A, Help & Troubleshooting] helios.z3r0:
This has probably been asked before but a search didn't yield any satisfying responses either way.

The Moto X has a handful of features unique to itself that are very nice to have. I had the first generation and fell in love with it. With my Nexus 6 I love having the Nexus feel, but I want some of the features.

Have any ROMs ported over some of the software features of the Moto X? Some features are in Lollipop, but I'm wondering if anyone has ever tried to port over the gesture to launch the camera, or try to port over the breathing active display (Google's variant is very underwhelming and not very responsive to light changes). Since Motorola made the hardware, I wasn't sure if there was some cross compatibility, or if any attempt had been made.

Hello!

I formatted my LG Optimus F7 (ALL partitions system, data, cache, etc.), and I didn't make a nandroid backup. I've been searching over the internet, but I haven't been able to find a suitable fix. The LG website's official firmware (filename.cab) seems to be corrupted. I found a couple links to the firmware that are all broken...

After all of the searching, I tried to connect my phone to a PC in download mode, and for some reason, it connects and disconnects after about a minute, so I don't think it would be possible to solve the issue on PC.

I think the easiest fix would be to flash a nandroid backup. If it is possible for someone to upload a system.tar, or a similar nandroid backup for the system, it will be greatly appreciated.
