Kernel control - T-Mobile Samsung Galaxy S7 Edge Questions & Answer

I have done some googling, and perused the play store, and I have a question: Which kernel control app would you recommend for rooted G935T on BQH7 (7.0) firmware? Kernel Adiutor is lacking in settings I can adjust/fine tune compared to kernel control apps I have used previously.

Don't root man. It is not worth the lag and battery drain. At this point in time, there are very little things that root can give you compared to stock rom. Speaking of rom, this device doesn't support rom due to locked bootloader. So in the end, just stick with stock and enjoy your device as it is.

Already rooted, mainly to get rid of Lookout, other carrier bloatware, and Samsung apps I don't want. Only rooted because the phone was finally getting sluggish, no matter how many cache clears and reboots. Kernel Adiutor is the only one I've used so far that allows setting the governor correctly for *both* sets of cores. Holding out until the Razer phone is on T-Mobile, I think.

Just a tidbit - set governor to Performance for both Big and Little, and changed I/O Scheduler to NOOP.....and damn! Good as new! (after making the settings changes, I also booted recovery and wiped cache partition.)

[Q] Changing the kernel on my motorola milestone x- help please

Hey folks. Being the noob I am, I posted on here a few days ago asking how to go about rooting my phone. Well, thanks to some friendly advice (and DoomLord's easy rooting toolkit) I have been able to clear that hurdle. Now that my phone is rooted, I would really like to be able to take advantage of all that has to offer (overclocking, underclocking, better battery life, etc.). From what I've read on the interweb, I need to flash a custom kernel to do that. Before I jump into this task, I have a few questions:
1) Do I need to flash a custom rom to use a custom kernel?
2) I am on a small, regional cdma carrier. Would changing my kernel affect my baseband, causing me to lose data coverage, or even lose cell service entirely?
3) will doing these things cause me to lose all my apps?
Custom kernel are not available to flash, being that the boooader is locked; however, the stock kernel supports overclocking, undervolting, etc. so you need only download an overclocking app.

So just for the safety's sake, the stock kernel:
2.6.32.9-geadffa3
[email protected]#1
Will work with an app like setCPU for over/underclocking, undervolting, etc?
Also, could you tell me some good clocking settings for the droid/milestone x?
The stock kernel allows you to overclock using those apps. However, I think there have been some issues trying to overclock the X if you are running an ICS custom rom. I think I read that QuickClock was working, but I'm not positive.
As for OC settings, each phone will act a little differently. You just have to test them out and watch to make sure your phone continues to be stable. You can start out testing at 1080 or 1100 and take it from there.

[Q] Would rooting/installing custom rom improve Nexus7?

I recently rooted and installed a custom rom on my phone and noticed huge improvements. Noticed my nexus was lagging on things that I would think shouldn't be that taxing on the device. Thought the OTA update to 4.2 would help but it didn't. Would rooting it get rid of that lag or is it just a nexus thing?

Personally because of the big change over from 4.1 to 4.2 i decided to go back to stock for awhile and wait for the bugs to be sorted.
Re-unlocked and rooted, flashed faux kernel and is the best experience i have had to date. Meaning the least lag. Stock and custom kernel. Just unlock - root and then flash kernel. :good:
Not a detailed description but if you need further advice just say so......Just means unlocking installing CWM and SU...Then flash kernel of choice. recommend faux..
I've tried out a rooted nexus 7 and to be honest didn't see a huge improvement so I've decided to wait until Key Lime Pie comes out and see if they sort out the bugs otherwise I will root.
Kind of discouraging
root doesnt automagically improve the devices performance, its what YOU do with root access. oh, and what lag? not the tiniest bit of lag on my device. custom rom/kernel, and some optimizations. couldnt be happier. btw, mostly whatl root does is let you use root apps. you dont need root to flash custom roms/kernels. but you do need an unlocked bootloader. with root, you can control that rom/kernel, get to the devices main file system, change whatever you want, and otherwise be in complete control of your device.
I get my nexus 7 today, after a hour I rooted it, just for ad block plus and the ability to customize the navbar. Love root.

There will most likely be more updates to 4.2 before Android 5.0 comes out.
I personally think it does make it better. It all really matters how you use your tablet and what you put in it like the Kernel you install. Roms it really doesn't matter really what you get but I have always been a big fan for CM since first getting the G1, nexus one, the HTC G2/Desire z and it has always been the fastest rom for me.

I had thought you needed SU access in order to flash a custom rom. Or is that just to use CWM which needs SU? Anyways if you unlock you must as well root it.....yes....!
Yeah as a few people have already said root alone will do mouthing for performance faux kernel, as far as I'm concerned, is a great addition to this great tablet.

I actually get a lot of performance lag. Might be from alot of email sync but still it shouldn't have a half second delay after lock screen and moving between screens etc.
And I thought I would need to root to get my bootloader unlocked? I'm sure it's easier for the nexus than my HTC One X. Which was kind of a pain.
Yes using different roms and or kernels will make a massive difference to performance and or battery life but thats determined by which kernels and roms you use some are built for speed others for battery. If you had searched the forum you would have found this :silly:
Root will break some apps.
Just wanted to mention that unlocking your bootloader and rooting will break a few apps for the Nexus 7. I was all gung-ho to root my Nexus the first week I had it. Then I discovered I could no longer stream cable tv to it with Time Warner Cables app. Google Wallet also wouldn't let me link any cards to it's app while rooted or with an unlocked bootloader. A quick skim of the forum shows that rooting breaks streaming functionality on other subscription video apps as well. Depending on how you use your tablet, this might not matter to you. I ended up going back to stock for now, just because I wanted to use these apps. There is probably workaround, but I just didn't want the extra work....around. I think the Nexus 7 ultimate toolkit might let you gain temp root, I don't remember for sure tho.
Rooting will not effect performance at all. Your just gaining access to the root directory. It's what you do after that effects performance. Also just rooting does not effect the wallet app at all, this is wrong information. Wallet does a root check for security purposes and will show "unsupported device" within the app after rooting. Ignore that, it is just a root notification. Cards add correctly and it functions correctly. I can't speak on the other apps mentioned, but ill take a stab in the dark and start at user error
Custom roms will definitely increase performance. Stock 4.2.1 is a bit laggy, I recommend flashing liquidsmooth and see the difference!

I stream movies using Flixster with my rooted N7. It's simple if you are rooted with Supersu. I go to settings in the Supersu app and uncheck Enable Superuser. After I finish streaming, I go back and enable it again.

[Q] Upgrading ROM etc.

A friend saw my Samsung Note 3 performance & asked if I could do anything for her Razr M.
System - 98..7.XT905.Retail.en.au
Android version - 4.1.2
I haven't rooted a Moto before so I did some reading - seems very different to Samsung methods and also seems to have far more ways to do it and also, the thing which gives me pause, a wider variety of things to go wrong. Don't get me wrong, I am not afraid of risking my phone - I have bricked my S3 and my Note 3 quite a few times in searching for performance and function.
But this is someone else's phone and she gave it to me for a day!!!
So, given all she really wants is better performance, I'd appreciate any advice on what I should tackle.
Some Q's... (as in point me to threads - I can read and work things out but some pointers on where to look can save me having to read all the threads in all the forums for a phone I will probably never touch again)
1. How do I protect against bricking? i.e. what is the standard way to reflash a stock ROM if things go wrong?
2. Is there a Moto repository for stock ROMs? Sammy has sammobile.com where all new releases (and old) are available for DL - does Motorola have similar or is it just Google and hope?
3. What level do I need to go to just to give better performance? (e.g. on my Note I did a lot of debloating to improve things, but that came after root, kernel and custom recovery so I could remove system apps etc.) Do I need to unlock BL or just root and install a custom ROM?
4. At first glance there doesn't seem to be many custom variations of the stock ROM, mostly CM and AOSP types. I am not sure how different that would make her phone to use, so I am assuming I'd be better sticking with a stock-customised ROM - is that a correct assumption?
Thanks for any assistance...

Stock ROM repository for XT905 -> http://sbf.droid-developers.org/phone.php?device=20
You should be able to use towelroot to root it.
Can't help much further since I have XT907
Edit: You could try freezing some unneeded bloatware (I know there's A LOT of that on the stock ROM for my phone) to free up some memory improve performance and conserve battery

Thanks for the help. I'm learning... I gave her phone back with just a few tweaks and will get it back when I am confident I can unbrick anything that might go wrong.
In the Sammy world, freezing apps requires root - same in the Moto-world?

Root will be required for freezing system apps, not for users apps. Rooting should be fairly simple (hopefully). Install, supersu from the playstore, have data/wi-fi internet connectivity, install towelroot and use that to get root.
Don't let her update it the latest update breaks root. Hopefully she is on kitkat and that is why her phone is performing poorly. Root with towel root then run motoapkakypse.apk to unlock the boot loader. Now honestly there aren't any Roms I'd call a daily driver yet with the kitkat kernel so you'll have to downgrade to the jellybean kernel and install one of the top 3 or 4 Roms... I'm still on stock I found that location services and a few wake locks were the problems and fixed them with an app called app ops

Heat && slowness with any custom kernel(ael/emotion , etc)

Hi,
When I first got my Note 4 I flashed it with a custom ROM and Kernel maybe an hour after I bought it, and since then (that almost a year ago) I was never with the default ROM + Kernel from Samsung ,as I was annoyed it was always full of bloatware(they even put facebook app comes as a system app).
However now with 5.1.1 I've had non rooted defualt samsung kernel+Rom for 2 days and it was smooth(no issues/slowness and even the best score I've gotten on antutu- over 52k), never got a hot and was fun to be with.
Now I've flashed AEL just to get root and it started getting a bit warm/hot even after not using it with heavy loadings, (even after underclocking ) and the same with other custom kernels I've used this year for 5.0.1 (emotion mostly,ael, and the one that comes with CM when using cm).. and thats even after I deleted 60 useless system apps and made only the needed apps to start with the phone!
the phone feels smoother/less warmish with default kernel + bloatware then without.
Did you guys notice over the past year that your device gets a bit warmer/sometimes slower when actually using a ''better'' custom kernel with much more optimizations and development?
can it be that the default kernel is actually better?

I'm just now considering this because my phone lately, even before upgrading to 5.1.1, is staying quite hot..
To test this I would need a flash able zip or tar with the stock kernel from 5.1.1. Do you happen to have one?

there are a few threads here on general that people uploaded 5.1.1 to them and gave instructions. let us know if you do it and have any improvment!
I have 5.1.1 but not the stock kernel... They gave instructions on how to extract the kernel from the rom image?

so far I think you have to flash the whole 5.1.1 with the kernel and lose root with it. not sure though

CPU Cores Stuck At Max

Anyone have anything similar happen?
On OOS 10.5.13 rooted with Magisk stable 20.4.
Tested on several kernels, same results.
A reboot fixes this temporarily but eventually will go back to max. Any help would be appreciated!
What kernel are you using?
What ROM?
Are you in performance mode?

So it's not going to be anything to do with the ROM. I'm on 10.5.12 UK which is the same as 13 in your region.
Honestly, I'm on xXx and rooted.
Just don't flash the kernel tweaks..
Just go with the stock kernel.. performance seems to be the emphasis on all of the custom kernels yet battery doesn't..
This is a side effect of it..
The reason it's been inherited between kernels is because there are values or even a few changes which haven't reverted.
You may even need to reinstall the OS. Unless you can isolate the changes causing it..just saying. Maybe quicker.

It stays stuck permanently. Rebooting helps for a short while but then it goes back.
Yeah I haven't tried stock yet but something tells me it's not kernel related, but possibly some app or module.

I don't have any kernel tweaks installed, just a couple of Magisk modules like systemless hosts for AdAway, fonts, and BusyBox.
Having trouble isolating the issue so I may need to wipe and start fresh. Just thought maybe a user here had a similar experience and could tell me what caused it for them so I can fix it myself.
Appreciate the responses!
Welcome mate, tbh though I don't shouldn't say you need a kernel for performance.
Maybe battery life but tbh the stock kernel does a decent enough job..if you do wipe, I wouldn't bother with custom kernels.
The performance is defined there already.

Yeah I just try to find a more lightweight kernel where OnePlus' debugging is removed. Maybe the difference is not noticeable in performance/day to day use so I guess for me it's more of a OCD thing lol
I mainly only like high brightness mode in terms of kernel features. Otherwise I get about the same battery results with every kernel, which is 11%-15% drain per hour.
As for this CPU issue, it's been flawless all day. I'm trying my hardest to stress test the device to see what exactly triggers it. If it remains fine throughout the night and by morning, I guess I saved myself a couple of hours for wiping and getting my setup back!
Will keep this thread posted if I ever manage to find the culprit.
Did you end up finding the culprit? I'm facing the exact same problem. I'm on stock 10.5.13 global, stock kernel. Rooted with magisk 20.4, No mods except for youtube vanced and adaway. Any help is appreciate Ed.

Unfortunately no, however I don't have the issue anymore after switching to Omega Kernel.
I'm not trying to say the kernel I was previously on caused the issue, and that Omega resolved it; just saying that's the only change I made and now my CPU cores are behaving normally and haven't given me problems since.
Maybe try playing around with custom kernels yourself? Also check for what apps you have chosen not to be battery optimized, could be a potential culprit as well.

Issue came back just last night...frustrating. Noticed battery life was going fast, might need to factory reset at this point.

Mine hasn't come back yet, everything is still good thankfully. I'm still on omega. I just can't wrap my brain around this one. And no one else seem to be experiencing this problem.. I searched high and low on this forum, believe me. You and I are the only ones reporting this so far i think.

Yup, seems like it.
Might bite the bullet and reset this thing when I get some time this week.
Update on this issue:
Ended up factory resetting shortly after I originally posted this and everything is working as normal!
Switched to the Pixel 5 though, so will not be keeping an eye on this thread any longer. If anyone else experiences this, seems like a factory reset will do the trick if all else fails! Just install everything back one by one to ensure it's not an app or mod causing it.
