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.

Samsung G Edge 6+ & ROOT

Hello
Very new to all this, as I've just switched from Apple to Samsung and my hand set is being delivered today.
I have a million questions, but the main one right now really is how do I go about Rooting my new phone, on EE without tripping KNOX?
I've been doing some research but I'd really appreciate someone with experience helping me as there's a million guides online, a lot from America, which is why I've given my provider above, as I'm unsure if this changes anything.
All help is appreciated

Why do you need to root?

For now, rooting will cause knox tripping and loss of Samsung pay possibility.
So my advice is to wait for some time if you want to keep knox and Samsung pay .
Personally I prefer wait the end of my warranty before rooting my device . But it's your choice.

You don't need root to change DPI:
Code:
adb shell wm density <DPI>
Then reboot:
Code:
adb reboot
I actually don't know the default density setting to restore things if you mess up. I should also add that I've not tried this on this particular device but it works on everything I tried it on.

Any idea what the default DPI is for the Edge+? My build.prop backup is bugging out. I show default as 160 in backup but that's too small to boot to.

ro.sf.lcd_density=560

Anyone tried to root S6 Edge+ with Engineering Bootloader? I have it on my old S6 and was perfect to keep KNOX 0x0.

Root vs. Security

Hi there,
As far as I could read, we now have a stable kernel(arter97) and a deodexed rom for the G928G.
With security in mind, regarding the Edge+, I am starting to feel that if I root my device, I will have a lot more posibilities concerning getting it more secure. For example, I would be able to use a firewall, uninstall default apps and bloatware, just for starters.
Otoh, a rooted device might be less secure if you are not careful... but I read recently that new malware is capable of rooting android so, basically that defeats my entire argument about not rooting it.
From your experience, would I be able to use a rooted device with arter97 kernel and the deodexed ROM above (without bloatware) securely?
In your opinion, what additional steps should I take?
Would I be able to revert to a stock ROM / original state that would enable me to use samsung pay, or rooting is a one way trip?
Are there any additional features that rooting would disable besides samsung pay (I also have a Sony Z3 and rooting it would disable taking high quality pictures with the camera)?
Thanks in advance!

I thought those were tough questions at first, but not that much
Ten days later, I have found an answer for question 3. Right now, afaik there is no way around a tripped Knox and there are no guarantees that it will ever be or in a near future.
I am still looking for ways of getting a more secure platform.
Started thinking about the original idea (ROM and kernel suggested), using a firewall, a VPN and a service like adguard as a local proxy.
Any further ideas?
Thank in advance!

Yes if you are carefull and not install hacked apps. Pay for your apps it's more secure (not always but more).

For now it's a one way trip, as it's based on knox, if you trip know you will lose Samsung pay.

You will lose all Knox possibility. Samsung pay, and maybe some other thing. But I don't think you'll lose High Quality pictures.
Hope I answered you a bit .

Ok, so rooting = trip knox = disable (forever) all features that rely on it, like samsung pay.
One last question: let´s say I root it and use it rooted for some time. Will I be able to revert to a default samsung ROM even with KNOX void = 1? Once I get back to a default rom, will it update automatically or that will be broken?

Yes you can go back to a default ROM (ie not custom status) but with knox void by just flashing a stock ROM via Odin - once knox is tripped it is always tripped and you will NOT be able to use Samsung Pay and there is no reset for Knox (Know=1), there are other pay methods that might work and some work when rooted too

If you go on official samsung firmware I think you could have automatic update. I might say I never go back to samsung official rom when I installed custom rom, only when I sold my phone so I don't know if it update after lol.

LOL that´s exactly the reason behind my question... If I sell it some day at least make sure that updates are coming through...

The main reason I haven't rooted the phone is because of Samsung Pay, if you don't plan on utilizing it then by all means root the phone. And yes even if Knox is tripped you can still receive the updates, I have several rooted galaxy devices with Knox tripped and I still receive the updates. On a side note if you update a rooted phone you will most likely loose the root and have to re-root again.

Thank you! I guess the only drawback for me is a practical one. Every new update means that settings won't be preserved. Anyway I think I can live with that.

Oh... following the procedure to root, I have learned that flashing the ROM is not mandatory. In other words, you flash a custom recovery, arter97´s kernel, install SuperSU and that´s it...
At this stage, will automatic update work?
(of course, I understand that if it does, it would reverse to a non-rooted device and I would have to do it again)...
Does rooting reset / wipe the device to factory settings?

Yes, custom roms are mostly for added features but it is not mandatory.
Automatic Updates should work, and rooting/re-rooting does not wipe your phone.

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.

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

Substratum for non-rooted Oneplus 8 PRO

I wouldn't hold my breath if I were you. That's one of the reasons I buy unlocked phones and not from Verizon. I unlock it, root it, install Adaway and Swift Installer right off the bat.

Not that I know of. Why are you hesitant to root? It's not hard. You just need to do your homework and follow instructions. We all had to start somewhere. Also, if something goes wrong, it's rare to really brick a phone. They can almost always be recovered.

There's no risk to rooting. Grab the MDM tool it's your always go to tool to bring phone back to stock if there's an issue.
I used to root for Adaway, Viper, and Substratum but with the theme engine now and Blokada (or my personal VPN) and most of my audio listening is not on this device I actually haven't rooted a OnePlus phone in almost a year. Keep in mind if you root you'll lose L1 provisioning (capped at [email protected] on YouTube TV which is a deal breaker for me) along with Netflix and other things that require Widevine DRM to play HD content. Also, having to update the ROM you gotta disable Magisk modules, disable substratum themes, flash the OTA, then reflash TWRP, reflash Magisk, re-enable all your modules and themes. At least this is how it was on the last round of OnePlus devices. Maybe I'm getting older but just simple flash OTA and reboot at my leisure and everything still just works...

Most apps can be light or dark theme.
You can also install DarQ from XDA Labs to dark theme more apps.
Quick Settings in the app store allows you to add a ton of more toggles to quick settings.
Hope that helps.

It's a bit old but you could try Andromeda from the play store and follow the instructions with substratum both installed and access to a PC worth a try couldn't shouldn't hurt

its pointless anyway
even on rotted OxygenOS most themes dont support it so there are always issues with themes
I prefer running custom AOSP ROMs as then themes work much better in terms of versions etc

I'm using Swift Installer and no problems. I have just about everything blacked out.

Many packages are supporting it now. Liv Dark, Swift, Darc, Liv Light, Valerie. Def worth the few minutes to gain root access.

Given there's no TWRP support as long as nothing goes wrong I agree. If during a flash or if the phone randomly wants to glitch out causing a bootloop during normal usage you're sitting with a paperweight unless you're in front of a computer with ADB and your files available to jump start this device in fastboot. No TWRP and rooting and flashing the boot partition to gain root in most cases likely fine but you're playing with fire without a way to attempt to fix your device while on the go. Correct me if I'm wrong and I might reconsider my personal stance.
In addition, I love this device for the option to root, but the L1-->L3 downgrade in DRM provisioning is a partial deal breaker for my personal usage with YouTube TV. I like to watch sports and being restricted to [email protected] is awful. I could deal with the 480p component but the lack of 60 FPS hockey and football are motion blur central. Keeping it not rooted keeps it at [email protected] or [email protected]

Don't root if you have no idea what you're doing
But like everyone said previously, root is THE thing to do once you got an Android
There's no harm for your device, if you fail, you flash a whole firmware and youre good to go again
