[Galaxy Note 3 Accessories] Blue Soul Slayer ♫:
I'm slightly curious. Does the note 4 Spen stick out slightly or you can sometimes notice it because you can feel a tiny bump. Does the note 5 Spen stick out? Or does the note 5 Spen falls out because it is to slim? Finally are you using a custom room or stock?

Thanks in advance ° w °
[Galaxy Note 3 Accessories] golalmo:
I'm using the sview cover which is slightly bigger then the device, so the N4 pen does not stick out.

Never tried to fit the N5 pen just because the N4 pen works better (on N3 device of course).

I'm using phronesis N7 custom rom and there are no issues with the spen.
[Galaxy Note 3 Accessories] jafferkhan:
i have all three, a Note 3, 4 and 5 ... the 4's pen fits but it's hard to get it out, which makes it useless, the 5's spen is the best because the point isn't pushable or something, somehow, i managed to stop the nib being pushed inside the 3's spen and it's works better than the 5s in my opinion
[Galaxy Note 3 Accessories] abinav kp:
I tried note 4 s pen it's working fine on my n9005
[Galaxy Note 3 Accessories] TheMadScientist:
I used a note 4 stylus in my note 3 but note 4s has ridges on it or ribs what ever you wanna call em... they have to be filed off for it to fit properly
[Galaxy Note 3 Accessories] TheMadScientist:
how did u get it to fit?

They do not fit unless you file or sand the ribs off them..
[Galaxy Note 3 Accessories] perosredo:
Anyone know of a good vendor?
[Galaxy Note 3 Accessories] abinav kp:
I Meant the other S Pens Work fine but they won't fit into the s pen slot of note 3
[Galaxy Note 3 Accessories] alexetna95:
Note 3 S-Pen fits only into Note 3 body. The only change you can make is to change the rubber tip of the pen to the Note7/FE/8 type.

It could be the best solution as a film screen protection for the S8, anyone tried it?

If yes how does it feels after a while (rubbery)? Does it peel?
[Samsung Galaxy S8 Accessories] Mr. Orange 645:
Link? And why do you think it's the best solution?
[Samsung Galaxy S8 Accessories] x017in:
Feels like peel. However thats not the bad part. The worst part is that it has a haze n the screen looks bad
[Samsung Galaxy S8 Accessories] Batfink33:
Yeah, that's a really bad film protector. The best film protector by far I've used is the Yootech wet apply. It's really great and pretty invisible although it'll give no protection if you drop your phone.

KPPD Control

Hey everyone! I know many of you are a big fan of [MENTION=4316709]savoca[/MENTION] 's KCal daemon KPPD. It is KCal for select chip sets on rooted phones that do not have KCal built into the kernel, or for phones that the KCal only partly supports.

KCal is a tool for adjusting the color, saturation, contrast, etc., of your screen, post processed. That means it happens after the image is drawn, and only affects what you visually see, so a screenshot is not affected by this. this helps you make your display show true black, and all sorts of cool color effects!

You can read more about KCal here:

https://xdaforums.com/showthread.php?t=3165247

And a couple of quotes from savoca:

However, the LG G4 has an 8992 chip, and it works too. So you could always try it if you have a Qualcomm chip. Be sure to let us know the results!

All the credit for KPPD goes to savoca. Using his tools used to require installation at the terminal or with ADB. Then, to make changes required hand editing a text file. But praise God, not anymore! now you can just use this app to handle everything from installation to making adjustments!

Feel free to give it a try! I made this app under the Apache 2.0 license, so fell free to borrow anything you need!

After install, you must give the app permission to read/write to the phone.

Go to:

Settings --> apps --> kppd --> permissions

And turn on storage.

Note: If you turned on storage permissions, but it still says "error, check permissions" then go to your sdcard, and create a folder called "documents" (if it doesn't exist) and in that folder, create an empty file called "kppd.conf". Then try the app again. This happens on some ROMs, and I'm not sure why.

Google Play Store:

https://play.google.com/store/apps/details?id=com.alaskalinuxuser.kppdcontrol

GitHub: (The app folder has a copy of the apk as well, if you don't use the play store.)

https://github.com/alaskalinuxuser/app_kppdcontrol

I have only tested this on a T-Mobile LG G4, but it should work on any KPPD/KCal compatible (mdp5) device.

Enjoy! And feel free to comment!

Thanks sir

This is what i wanted

To change values everytime editing the file was very messy

Thanks sir

And also to savoca
[G4 Themes and Apps] AlaskaLinuxUser:
Thank you, I'm glad you like the app!
[G4 Themes and Apps] rocker00:
[MENTION=7026648]AlaskaLinuxUser[/MENTION] thank you so much for this.

i used to use kcal on my sony xperia z2 on stock marshmallow rom with compiled kcal module but now i am on resurrection remix android 7.1.2 (aosp base), i installed the app but i can only adjust RGB same like the built in feature live display but i can't adjust anything else like contrast saturation,values...etc, from what i readed i should be able to adjust everything same like kcal even without custom kernel ! or should the kernel supports kcal to be able to adjust everything ?

thanks again for the app :) .
[G4 Themes and Apps] AlaskaLinuxUser:
rocker00,

Thanks for the kind words.

Two thoughts:

#1. Could you open the /sdcard/documents/kppd.conf file, and manually edit it to pa version 1 instead of 2? Then try editing (manually) the file values and press save. Does that work? Be sure before hand to open the app and enable once to get the kppd running. This will see if you have pa version 1 or 2. My app is only set up for version 2, but I may need to make a settings page for version 1 or 2.

#2. If you manually install per savoca's kppd thread (link in op) does it work? If not, then it is a problem with the kppd, not my app.

I am not trying to duck the problem. Just trying to isolate if it is my app or kppd itself. I didn't make kppd, and kppd may need to be specifically edited and compiled for your phone, I'm not sure. Was there ever a working kppd (not KCal, which is in the kernel) for your phone?

Also, for grins, can you send me a log cat when it fails to work?

Thanks!
[G4 Themes and Apps] rocker00:
Thanks for trying to help and yeah sure i understand you are just trying to figure out where is the problem !

i will do what you said and i will let you know the result.

Thanks.

Edit: [MENTION=7026648]AlaskaLinuxUser[/MENTION] tried both ideas, changing pa form 2 to 1 & installing manually without your app but still the same result ! only able to adjust RGB ! so, obviously the problem is not the app itself but in kppd or something in the rom !

anyway thank you so much for the app and for trying to help and also lets wait for feedback from the other users !

best regards :).
[G4 Themes and Apps] AlaskaLinuxUser:
Do you have a link to the threads with the compiled kcal module? savoca made kppd open source, so if the thread has any clue to the girth commits to make it work on your phone, perhaps there is something we can do. Perhaps, no promises, and it's a long shot.... :)
[G4 Themes and Apps] rocker00:
here is the thread for the module https://xdaforums.com/crossdevice-dev/sony/5-x-kcal-module-flashable-t3159869 , the rom which i am using right now supposed to use 3.10 kernel but it uses 3.4 kernel to have a fully working camera due to the lack of camera blobs source from sony, since i am not linux user unfortunately i don't know anything about compiling :D but i also feel that it's a little bit complicated in this case !

Thank you so much :)
[G4 Themes and Apps] Spookymyo:
I'm assuming that because this deals with modifying the kernel that you have to have an unlocked boot loader. Which means this won't work for a Verizon LG G4?
[G4 Themes and Apps] AlaskaLinuxUser:
This actually does not require an unlocked boot loader. The KPPD daemon runs in user space, but root is required. I have only tested on the T-Mobile G4, but it should work on any rooted G4.

I would appreciate hearing your results if you have time to test it. :D
[G4 Themes and Apps] obol2:
Does not work on LG G5 :(
[G4 Themes and Apps] AlaskaLinuxUser:
Thanks for testing it!

Question: did it not work at all? Did the r g b multipliers work, or just not at all?

Sorry, just read up on the LG G5, it has an 8996 chip, which savoca did not list as applicable. Then again, neither is the G4's chip, the 8992, but it works on the G4 anyways. Sorry that it does not work on the G5.

Also, if you have time did savoca's original kppd work? Sorry for all all the questions. Thanks for taking the time to test it!

Forgive my ignorance, too, but is the G5 chose on the list of chips in the OP (just updated, was not there before now)?

If so, which version? Notice in the text file there is a "pa" version. You may need to change to 1, 2, or 3 depending on your version. If that is the case (and them editing the text file works) I could add a settings for version number also.
[G4 Themes and Apps] Ghisy:
Hi there!

Would this tool work on a Nexus 6P running Pure Nexus with ElementalX kernel? I had been using savoca's Color Control app but it doesn't work anymore on Nougat.

Thanks!

[G4 Themes and Apps] suvam69:
Works on msm8953 chip?
[G4 Themes and Apps] AlaskaLinuxUser:
Great question!

Yes, it should work.

On the original kppd thread (link in OP) a 6P was using it. They did mention a specific 6P glitch, though, that if you had the screen off when kppd applied, the colors would look funny. So give it a try, but keep that glitch in mind, you may not want the set on boot.
[G4 Themes and Apps] AlaskaLinuxUser:
I don't see that on savoca's list of approved chips, but neither was the G4's 8992, so feel free to give it a shot. I'd like to hear how it turns out. If it works, we can add it to the list. :D
[G4 Themes and Apps] marn3us:
Thanks for the awesome job! This app makes KPPD so much easier to use :)

Btw, does anybody have a display-calibrating tool to find the right values to have the G4 calibrated to sRGB colorspace?

I'm asking because most of the internet content is sRGB so it would be amazing to achieve a better calibration on our G4 (which has horrible factory calibration).

Thanks in advance :)
[G4 Themes and Apps] ReDuXX528:
Hello!

Im using a RN4x with snapdragon 625. I can't get that app to be working :/ i gave it already root permissions and to memory, but it still says "Error: Please check permissions". What's wrong?
[G4 Themes and Apps] Spookymyo:
I gave it a try. No luck. Doesn't work for rooted Verizon LG G4. When I open the app it prompts me for root which I grant. Then I click the install button and the phone restarts. I open the app again and there is no control panel it only shows the install button again. Tried it a few times with the same results.
[G4 Themes and Apps] AlaskaLinuxUser:
Did you give the app storage permissions?

Go to:

Settings --> apps --> kppd --> permissions

And turn on storage.

That should help, let me know if not.
[G4 Themes and Apps] mvaenskae:
Cheers,

see my previous post with the logcat information. Fixed the issue on my end with the Redmi Note 4 about the app not loading.

Sadly it doesn't support my device though :(
[G4 Themes and Apps] AlaskaLinuxUser:
Go to:

Settings --> apps --> kppd --> permissions

And turn on storage.

The app is giving the error of permission denied to read/write to the file.

Try that and see of that helps. Let me know if it doesn't.
[G4 Themes and Apps] Spookymyo:
I'm on android 5.1, its the only version that can be rooted for the verizon lg g4. I don't think you can manage individual app permissions in 5.1.
[G4 Themes and Apps] AlaskaLinuxUser:
If you pull a log cat, perhaps we can see the problem.

If you go to your root explorer, does /system/bin/kppd exist? If so, the the install is working, but not the app. If not, then the install is not working.

Do you have busy box installed? If not, install busy box and try again, perhaps that will help.

Other than that, I need logs to see the problem.
[G4 Themes and Apps] ReDuXX528:
I've done that already but doesn't work
[G4 Themes and Apps] Spookymyo:
/system/bin/kppd does not exist.

I do have busy box installed.

I also have selinux mode set to permissive if that helps.

I'll get a log cat as soon as I can.
[G4 Themes and Apps] AlaskaLinuxUser:
Something you both could try is following the link in the OP and trying savoca's steps manually and see where the error lies. My app follows his steps. If the manual install and operation works, then I may need to adjust my app. If the manual steps need to be changed, then that shows where the problem is.

It should take about 20 minutes to do the steps manually. It would certainly help in troubleshooting the issue.
[G4 Themes and Apps] AlaskaLinuxUser:
Bummer, thanks for the update!
[G4 Themes and Apps] AlaskaLinuxUser:
Did it work for you?
[G4 Themes and Apps] AlaskaLinuxUser:
Have you found a good setting that you'd like to share with the group?

Here's mine:
[G4 Themes and Apps] mvaenskae:
Cheers! Would you know of a way to maybe debug as to where exactly the program is failing? Just curious as to maybe I could extend it for my chipset in one way or the other.
[G4 Themes and Apps] AlaskaLinuxUser:
So the kppd was installed, and the control panel came up in the app, but changing any settings and saving them had no affect?

There are a couple of things you could try:

#1: edit the file manually, notice that the pa version is 2. You could try 1 or 3, if your device supports that.

The real question is if your device supports mdss (QualComm's display driver) and is mdp3 or mdp5 compatible. My understanding is if you are mdp3 compatible, only the red/green/blue sliders will work. If you are mdp5 compatible than all will work. So, that leads to the following question/attempt:

#2: does the rgb sliders work from the kppd app? If so, but the other sliders do not, then your mdp is 3, and there is nothing more we can do. If it does not work, then you will be non-supported, which leads to option next:

#3: savoca released his tools on GitHub. You can download his tools and edit them for your device, however, if you do so, you will need a new app to control it, but I can help you with that if you were to make it that far....

link to kppd: https://github.com/savoca/kppd

link to kcal: https://github.com/savoca/kcal

Sorry, I didn't make kcal or kppd. If the original kcal or kppd do not work for you, I can't help you. I only made an app that installs and controls savoca's great work.
[G4 Themes and Apps] mvaenskae:
Cheers,

the app successfully launched I could set values on the sliders, but nothing took effect sadly. I will give the first approach a try later tonight, for now let me commence a bit with my research I did (as this may be a lot more helpful for either of us :) ).

Thanks a bunch for explaining how and where your app actually attaches itself into and giving a description of the terms plus effects. To my understanding kcal is supported on the SD625 and I see actual questions on the best kcal values in my device's forums but it may very well not be supported by MIUI's kernel. Here I can see the following thread(s) showing support for KCAL:

https://xdaforums.com/redmi-note-4/...-development/faust-kernel-7-1-2-mido-t3624515

https://xdaforums.com/redmi-note-4/help/custom-kernel-miui-t3647446

This post here makes me believe mpd5 support exists at least for one kernel:

https://xdaforums.com/showpost.php?p=72684205&postcount=4

I can try with a different kernel obviously and report back but with the current kernel I do not see any kcal related files in /sys/devices/platform.

Just to clarify. Is KCAL support enough for this to work or does one need KPPD as well?
[G4 Themes and Apps] AlaskaLinuxUser:
To clarify, this uses kppd and does not use kcal.

Savoca made kcal, which is a kernel modification or can be used through insmoding a kernel module. It does not need kppd to work.

Savoca then made kppd, a kcal post possessing daemon for people who could not mod their kernel. So kppd does what kcal did without touching your kernel, however it is not kcal. You do not need kcal for kppd to work. Kppd works on certain chipsets, regardless of which kernel is installed.

This app installs kppd, not kcal.

Hopefully that clears the water. Thanks for all the effort to test out a solution! I'd slap your thanks button, but I ran out of my 8 for the day.
[G4 Themes and Apps] marn3us:
Thanks for sharing! :)

Unfortunately I don't have any calibration tools (other than comparing to my calibrated pc monitor) so I am not able to properly adjust the parameters...

But since the difference from my two calibrated monitors (both pc and macbook) is quite noticeable, it would be great if someone with calibrating tools could provide us with tweaks for sRGB on our LG G4.

This is especially useful considering that most internet content and the most popular phones (all recent iphones and Samungs from S7 and on) are calibrated on sRGB ;)
[G4 Themes and Apps] obol2:
I gave all permissions and when I press install, it rebooted and when I open the app again, it shows the same screen as before (with the install button).
[G4 Themes and Apps] AlaskaLinuxUser:
I recommend that you try savoca's instructions to manually install kppd. If you take notes, we can see where the differences are in my app and the manual instructions.

The link is in the OP.

After installing kppd manually, and testing as peer his instructions, you can try opening my app to see if the controls work.
[G4 Themes and Apps] AlaskaLinuxUser:
Is anyone having an issue with the kppd app "popping up" randomly when start on boot is selected?

[MENTION=7026648]AlaskaLinuxUser[/MENTION] Trying KPPD Control on a LG G2 D802 running latest official LineageOS at the moment. addonsu is installed and enabled via developer options.

KPPD Control has ben granted permanent root permissions when being asked.

However, when KPPD Control is asking to install the KCAL Post Processing Daemon and configuration files, clicking on the big "INSTALL" button results in the following error message: "Error: Please check permissions...."

Do you have any advice?

Also tried the KCAL app, but it force closes immediately upon opening (might be because the LineageOS kernel does not have KCAL support built-in?).
[G4 Themes and Apps] AlaskaLinuxUser:
Yes, great questions.

Open system settings --> apps --> kppd control app

Give it storage permission. That should solve your issue.

As for the kcal control app, yes, it will just exit because your kernel does not have kcal built in.

Hope that helps!
[G4 Themes and Apps] wq0913562:
[MENTION=7026648]AlaskaLinuxUser[/MENTION] Thanks a lot for the swift reply. The storage permission actually did the trick, thanks, you were right. However: The only things which work are Invert, Red, Green and Blue. The rest does not work :(, which is unfortunate, because Saturation was what I was after :(.

Two more questions:

If Saturation etc. is not working using KPPD, would that mean that asking the LineageOS kernel developer to add support for built-in KCAL would be in vaine as well? Or is there a chance that built-in KCAL kernel support would make Saturation work?

Also: How do you fully uninstall KPPD Control? When clicking the big "INSTALL" button on the initial KPPD launch, it's installing KPPD and the configuration files. If I uninstall KPPD Control via Settings -> Apps, I guess that will not uninstall KPPD and the configuration files, right?
[G4 Themes and Apps] AlaskaLinuxUser:
Also really great questions!

#1.

SO, if only red/green/blue/invert work, then your device does not support the full kcal, and only has MDP3 support, as you can read here:

https://xdaforums.com/android/software-hacking/dev-kcal-advanced-color-control-t3032080

Having your kernel dev add kcal will only result in limited support, since your chip in your device only supports MDP3, if I understand savoca correctly.

#2.

You know, I never really thought about that, I should add an uninstall feature. As it stands right now, you are correct. Deleting the app only deletes the app. The two leftovers are:

/system/bin/kppd

/sdcard/Documents/kppd.conf

Which you will need root permission to delete the one, and just regular permissions to delete the other.

....wanders off to look at making uninstall button and code..... :D
[G4 Themes and Apps] wq0913562:
That's very unfortunate. Maybe he will answer over there: https://xdaforums.com/g4/orig-devel...ocessing-settings-t3165247/page8#post73451702

[G4 Themes and Apps] wq0913562:
[MENTION=7026648]AlaskaLinuxUser[/MENTION] Hmm, on the Google/LG Nexus 5 (which has the same processor as the LG G2 D802) it looks like KCAL is working with more than just R/G/B/Invert:

https://xdaforums.com/showpost.php?p=58892019&postcount=23

So, wondering why only R/G/B/Invert is working on the LG G2 D802...
[G4 Themes and Apps] AlaskaLinuxUser:
If it has the same chip, with the same graphics, and the same mdp# level, then it should also work. Unfortunately, I did not make kcal or kppd, I just made the "make it easy" app to install and to control it. So if you need help with kppd's function, I cannot help much with that. That is a question for savoca.

If your kernel Dev is willing, you could ask him/her to add kcal to your kernel instead, which works much better.

You could pull a logcat and see if you can spot the issue, also. Sorry I can't be more help.
