How to fix Gamma color on the S4 ? [ rooting experts requested ]

I found some apps that can fix Gamma but require the phone to be rooted.
How do I start with that ?? Will I lose phone memory ?
I have a sim-free S4 unlocked, with a yellow tint issue. Replaced it and the issue is still there. Apps online require the phone to be rooted in order to change Gamma settings.
Would appreciate any advice.

Did you adjust it from auto to dynamic. Under settings then display

Yep I have tried many various solutions, nothing works. I also exchanged the phone, still has a yellow tint.

I believe gamma adjustments require both root and custom kernel. For real screen caliberation you need to wait for bootloader unlock and subsequent dev support. In the mean time, try an app called Filter My Screen. It might help a bit.

Thank you for replying. Can you please expand on what you meant ? I just moved from an iPhone so kinda new to the whole rooting thing.
There are many kernels lying around in the forum here that supports the S4 : http://forum.xda-developers.com/forumdisplay.php?f=2261
What are those then ? and how does the bootloader unlock differs from it ? Furthermore, can I restore my phone after rooting if I change my mind ? (so that my warranty is not void anymore)

I dont see any custom kernels there. To find iut what they are, you gotta read the threads
Rooting and unlocked bootloader are different. One allows access to <root>, similar to your computers C:\ directory, the other gives access to the bootloader which basically dictates what happens prior to the Android OS being loaded....think of it as the BIOS of your phone or the master boot records. You should really read up more about Android OS in general before doing anything
I THINK you can root and reverse without triggering a flag, but someone whos done it shoukd answer that

Oh I see. So what is the solution for "Advanced Color & Gamma Control" to work ? Just rooting or using a custom kernel too ?

It says it in the first lines of the app description in all caps: custom kernel only, Nexus 4 only....you cant use this app.
And please dont double post in General and QA, it fragments responses.
Edit: if you have an unlocked sim free version, you should post in the international forum regarding development issues, not ATT.

[Q] Root De La Vega - > Change DPI -> Unroot... Warrany/OTA?

Hi all, I would kindly ask you if this may work. I have a Root de La Vega-compatible Note 3. I would REALLY like to change the DPI of my phone, but would like to keep the possibility of having OTA upgrades, and the warranty. So I am asking you if this will work:
- Root De La Vega (no Knox tripping)
- Xposed - change DPI
- SU Full Unroot
Is it possible? Otherwise, do you know any other way to achieve my goal?
If not, I'll just wait for a couple of Samsung upgrades and then forget about OTA and Warranty...
Thanks.

Has anyone used app settings (XPosed) to change systemui dpi? Will this affect all apps or only the status bar, settings, ...?
Does this work at all ?

I tried it. It only modifies Recent Apps and Status Bar. Works great! I'm on 400 dpi now.

for real dpi change you gotta edit build.prop, and that gets overwritten on ota updates most likely, meaning you need root again to edit it then.

Meanwhile I noticed that if I change dpi I am likely to have to change most apps, they are not properly resized. At least that was on the Note 2. E.g. keyboard small and offset, phone app to, etc etc.
I am probably putting a pin in this for the moment, I'll wait for one or two official Samsung and then blast away everything, if a reasonable Rom is out.
I hope that the Note 3 sells a lot so we can get high-quality roms with S Pen support...

[Q] SM-T530NU not full root help

It's the 10.1 inch
I just rooted my tablet today and gained su.
I can give apps su. I get the give su prompt box.
I used the Odin method from this site by chainfire.
Now I managed to kill knox. I closed and un-installed all 6 knox stuff with titanium backup. I did create a back up file for all of them but I don't think you can restore them.
I need busy box for some of my root apps to function because I need the killall.
For some reason busy box gets error message saying there might be a problem with my root.
Anyone have any suggestions?

I had the same issue on the SM-T530NU rooted using the Odin/chainfire method (I assume you're referring to the Play Store busybox app). The problem went away for me when I installed and ran Root Browser, which installs components of busybox on its own. After installing and running root browser once (follow the setup prompts), and then rebooting the tablet, I was able to run the original busybox installer app with no issues. No idea if this'll work for you but since it was the exact same set of circumstances, hopefully it will.

With custom recoveries available, cf autorooot isn't really needed.
At some point you are going to trip knox. But if you have successfully disabled knox, go ahead and flash
a custom recovery. Then flash chainfire's latest supersu update zip. Then find your busybkox install via market
or a custom binary.
If custom binary, push it to /system/xbin, then open terminal and su, then
mount -o remount,rw /system
chmod 755 /system/xbin/busybox
busybox --install -s /system/xbin
reboot

Settings > General > About Device tell me your Model number (e.g. mine is SM-T530NU) and I can tell you if it can be rooted. IF AND ONLY IF you have the same model number as mine, SM-T530NU (and by extension the one in the OP, the one in the title) this method will root your tablet BUT it will also trip knox, thereby voiding your warranty. If your model number is at all different do not use that link it could very well brick your device. Just tell me your model number, good chance there's a way to root it

Will someone please help me with this? Why can't I install busybox?

SM-T530NU is mine. That's what you needed right?
Now will I be able to unroot my device to play a game that won't run if I'm rooted?
Or is there a way I can run it and still keep my root?
I used the chainfires way of rooting and I just did the superuser unroot.
I went to the Samsung website and got the stock file for my device which is like 1.2 or so gb.
Can I put that back on my device and then wouldn't I be completely unrooted?
Also I used titanium backup to remove all the knox files while I had root.
Will this be a problem when I flash over my Samsung file I downloaded from the Samsung site?
I want to have full root but still be able to play this game ragnarok. Can it be done? Oh and using that lame hide my root from the Google play store didn't work. I hide the su binary and removed the suapp and it didn't work.

This will root your tablet BUT it will ALSO VOID YOUR WARRANTY

And what about my other questions? Can I hide the fact I have root? How?
What about if I want to unroot it? Will it be fully unrooted? How?
What if after I root it and then unroot it, can I root it another time? How and will it cause problems?
Is there a program like macro touch that I can use without root?
I feel that my questions are very simple and straightforward could someone answer them?
Someone that had actually done it and not just someone that thinks they know what their talking about.
Thank you.
He needs to make his own topic. I just put the picture of my device its freaking SM-T530NU can you not read?!

Jesus Christ dude are you illiterate I was providing a link to the other guy to root his tablet. But yes please, get me banned. Sic the internet police on me for all I care. You want your answers questioned? There are two invaluable tools just waiting to help you find your answers. They're called the xda search button, and google. You're a human being living in an age where we have the most immediate access to just about any information imaginable. I have around a dozen devices all rooted using a variety of methods and I am able to install and run any program on any one that I darn well please. If you're really going to tool around and hem and haw about a bunch of apps I don't know that I can help you.
You have the SM-T530NU? Fine, this is a surefire way to root your tablet. HOWEVER, in doing so you will trip knox, thereby voiding your warranty. If you don't understand that sentence, I revisit my earlier point of READ. Learn on your own, that's what I've done. But stop coming at me with your confrontational language, especially coming from a position of such a persistent insufficiency in knowledge and a lack of the motivation to rectify that shortcoming on your own.

You can unroot in SuperSU. It's an option called "unroot"
Yes it will be unrooted. Or you can just reflash system firmware.
I don't foresee any problems with rooting, unrooting, and then even re-rooting your tablet but even so if problems arose (which they probably wouldn't) there are ways to wipe/reset the tablet.
I don't know what macro touch is. Use google, the play store, xda, etc. to search for apps.
Yes maybe he shouldn't've asked his question here. Don't jump down my throat for answering it. I can read perfectly fine, I do it more than most and have been blessed with 20-15 vision.

3 Read search read.
4 XDA is NOT a tech support site or a customer service desk.
5 You want to mod your device? Cool. You pay the price.
6 Now this POV isn't particularly popular but, I believe Samsung has every right to protect it's warranty. You mod your device, you void your warranty. Fair is fair.
7 There have been numerous responses to your question in this thread which have been far kinder than this one. Try saying thank you.

Xposed with the V20

Has anyone installed xposed yet? What mods are you running?

Xposed is not yet compatible with Nougat as far as I know.
Sent from my LG-H918 using XDA-Developers mobile app

How about now? i was thinking to buy a v20, is it compatible with xposed?
theres root available right?

Thank you! So xposed is yet to come to Nougat.. but Rovo is working on it. I honestly, just like using the module where I can change the DPI of the app. Id like to change the DPI of the entire OS, but it would break my LG v10, so the module was the only way.
Root wise, this is fully rootable with recovery? I was reading that only the TMO version was able to be rooted?

Honestly, i have not looked into the depth that other carriers than Tmobile can be fully TWRP'd. There are Roms for the ATT version i believe. So at least root is available then at the very least, flashfire could be used.
I was never into DPI changing much, however, one of the settings on this phone allows you to change the size of your icons and text so the illusion of a changed DPI can be set I think. I'm not familiar enough with the benifits/results of changing the DPI.
i would look a little further into your carrier to make sure root is an option but I think most can be rooted. Hopefully xposed is in the near future but at least it seems to be in the possible future .

I just changed the dpi with adb. The LG keyboard wont work if you change it though, just use the Google one. You don't even need root to do this either.
adb shell wm density 480

Isn't system wide DPI settings a native thing in android 7.0 now? Thought I read that somewhere but I don't ever use it so who knows

[Q] Cons of Rooting and Unlock Bootloader

Hi, i just want quick answer for my question is:
What feature that I'll lose after root or unlock my Bootloader alongside tripping my knox? does it have any side effect to camera quality just like Xperia device which lost Bionz Software Processing function after unlocked?
Thanks

You'll lose Samsung Pay.
That's it.

Samsung health too, right?

No you will not lose S Health. I'm rooted and I use it regularly. But before using it you should edit build.prop file and change the line "ro.config.tima=1" to "ro.config.tima=0".
You can find the file in the root directory.

Android Pay may work if Magisk is able to hide root.
Samsung Pay will never work again because it checks the knox status and you cannot modify it.

Yes for both cases.
Samsung Pay checks knox status and since you cannot revert it to its original state, there's no way to get it working.
Magisk can hide root from Android Pay. You just have to make sure SafetyNet is passing. It's not 100%, sometimes Google change things and it starts failing again, but you can try anyway.
