How to make the Note 4 camera better: lift 4K video restrictions, lessen compression
The Galaxy Note 4 is already outfitted with one of the best mobile cameras you can carry around, as attested by our own comparison, but what if you could make it even better. Manufacturers put plenty of restrictions on today's handsets camera abilities, in order to balance thermal throttling, storage space, or both. 

Thus, 4K video footage warnings pop up when you fire up this mode, telling you that the phone might become hot, and you might be restricted in the duration of your video recording. Alternatively, makers compress the output JPEG files too much, leaving you with a manageable size, but lesser amount of details in the photo.

Fret not, however, as there is a way to circumvent these restrictions on your brand new Note 4, thanks to an enterprising developer, who hacked the camera app to lift the more annoying restrictions. Here's what you will be getting:

There are a lot more goods here, such as removing the 5 minute mark that would appear while doing 4K footage, plus the mod will work on both the Exynos, and the Snapdragon version of the Note 4. What needs to be done is, unfortunately, not simply downloading an app and installing it, and the phone needs to be rooted, of course, but you already knew that. Here's what needs to be done to install the mod:

1. If you have custom recovery installed, and if you've already rooted, we can't imagine why wouldn't you, simply flash the Note 4 camera mod zip, and that's that;

2. If you want to take the high road, use ES File Explorer, or any other app that will give you root system files access, go to /system/app and delete the old SamsungCamera3.apk and SamsungCamera3.odex files, or stash them away in case something goes wrong;

3. Grab the respective Exynos or Snapdragon versions of the SamsungCamera3.apk that is in the zip file you downloaded in step 1,  and copy it to the /system/app folder, then copy the media_profiles.xml file that is in the same zip package to the /system/etc/ folder. Don't forget to set rw-r-r permissions on both newly-copied files;

4. All you need to do now is reboot the Note 4, and marvel at your newly-found camera freedom with your powerful handset.

I hate it when manufacturers make such restrictions on camera. LG G2 is also capable of slow-mo but LG doesn't release such an update it, you have to root and flash a zip file unrelease it.

Sometimes its to give you a reason to upgrade to the new model. Sometimes its because they didn't think the feature was high quality enough to implement. Either way, this is a pretty spiffy upgrade to the device.

thanks.. at least some people appreciate it. I plan on working on it some more but decided to take a break after some confrontation the other day.

It will be great if we could add some s-log curve for video.

Will this void warranty?

Root voids warranty, so, yes.

"and the phone needs to be rooted, of course" ATT and Samsung : Let those of us who want root get it easily. No more mandatory KNOXturbation and locked down phones. Root is a significant part of why a lot of people buy an Android phone.

And so Samsung should make this option available without rooting: Turned JPEG quality up to 100% from 96%

Great app, love the UHD limit lifted, but it only records up to 4GB until it says Maximum Record Time Reached which is around 11 minutes, not 30. Please advise. Thanks

Correction: It only records for 8 and half minutes not 11 minutes as I mentioned about. How do I get it up to 20?

The 4gb limit is due tk the camera running off 32 bit written code. 32 bit maximum file size is 4gb. intil its written in 64 bit there are ways of doing it but it is well beyond my coding capabilities

Thanks Kevinrocksman that makes a lot of sense. What I don't understand is how the 4K limit has been lifted to 20 minutes and beyond, when it clearly reaches its filesize limit way before that?

Is is possible to put bit UHD and FHD bitrates back to standard 24Mbps and 20Mbps so that record times of 23 minutes and 28 minutes could be achieved within 32bits? Your response to this would me much appreciated by me.
