Does anyone know why our S7s become slow after rooting? - Verizon Samsung Galaxy S7 Questions & Answers

I've flashed and rooted countless devices before and don't normally run into issues with the speed of the device. Usually I root to help with that! Since I've gotten my S7 though, I've noticed that we all get performance issues after rooting. What would be the cause of this? Is it Knox? Maybe something Samsung implemented to encourage us not to root? Does anyone have insight on what causes this lag? I might have missed a post explaining this so feel free to link it in the comments.

My edge has slowed to the point i'm using an iPhone 7 plus now lol. Waiting for the s8 plus to come out

The engineering kernel that is used to gain root is a factory Samsung kernel used for development and repair, and it was not intended for all out speed. The only way to gain root without this particular kernel is to have an unlocked bootloader, which is not available for the US S7. You can look into the Hybrid ROM, as it retains the factory kernel, but you won't have root access after flashing it.

Could you point me to root procedures guide? Thanks

Rom help for s5

My s5 has continually gotten slower and slower. I would like to do root and install the fastest, cleanest least bloat and most stable Rom possible to speed it up again. I've. Never done this before on an s5 so am asking for advice and help. I am on the Verizon network and use my phone for business so I really do not want to lose any data on my sd card thanks appreciate all the help!
Bump anyone appreciate the help
Ask in the Q&A forum
K thanks this is q & a forum! Help appreciated or you tube guide
Ok...so you say it's a business device......does that mean it connects to a secure (enterprise) business nerwork? If it does, then root is NOT for your device. The network will discover root access and prevent connection.

It is now your thread was moved
No keith it does not connect to a business or enterprise network. I use it for work mostly meaning: internet surfing, email, and taking pictures for work related projects. I own my own business. As I said above I like the S5 but it seems to be getting slower with all these new updates & Ive read by rooting & installing a ROM you can debloat it & speed up the phone. Appreciate the responses.
You can root and debloat without flashing a custom rom, I assume your device is running lollipop? That being the case, you can use CF Root or TWRP / SuperSU combo to gain root, then use Titanium Backup to debloat.....
Here's a 'step by step' for the TWRP root method........
http://forum.xda-developers.com/showthread.php?p=64961009
Edit....just seen that you are with Verizon....that complicates things as they lock their bootloaders.....AFAIK, root methods for Verizon devices running lollipop don't exist.....although don't quote me on that....I've not had to deal with Verizon devices, so I haven't researched them.....

So that means there is no way to root or install a faster custom Rom with Verizon? I'd anyone else can chime in I would appreciate it.

Depending on your lollipop version, yes. Go check the Verizon s5 section.

All things root and Bootloader?

Hi Friends,
Hope you're all having a great new year. So last time I was lurking the S7E forums, we had a leaked Engineering Bootloader that was used to acquire root on all US Snapdragon models, albeit, with a lot performance issues and etc.
I came here to glance as well as all other variant forums for the SD model and now we have Root for every model, with even ROMs being baked like the Echo ROM for Verizon, Sprint, AT&T models, usually the toughest to achieve these things on. I'm trying to read through the forums, but I fear I'm missing the details, that will help me pull the trigger for getting the device or not.
Can one of you very experienced, knowledgeable, and kind members educate me on the latest?
1. Do we have unlocked Bootloader and Root for all US carrier S7Es? How is it done? I use people using Flashfire. So no TWRP?
2. Does this process still trip Knox and render Samsung Pay to never be used again on the device?
3. If I bought the Verizon variant, for example, can I root, unlock Bootloader, and etc, and then return to stock, to return to the store in case I don't like the phone?
4. Xposed Framework working for all models?
Much appreciate your responses, any and all of them in advance! Thanks!

1.) https://forum.xda-developers.com/sprint-s7-edge/how-to/root-t3410424
2.) No, it doesn't. And flashing back to stock will allow Knox to work again, as long as you didn't flash files from other sources (there are some that will trip Knox, so be careful)
3.) Return To Stock
A: Head on over to @psouza4's post and follow his steps in the return to stock section. The steps are easy and he's posted mostly all the firmware.
4.) Yep. Here's how to do it: https://forum.xda-developers.com/sprint-s7-edge/how-to/root-t3410424/post67601958

Hey bud, thanks for the response! So reading through your helpful post and links, seems like not much has changed, we still are using the ENG Bootloader to do the Root?
If that is the case, three follow up questions:
1. What is the difference and how are the ROMs like Echo and TEK created with built in root? And are we only able to flash them through FlashFire due to the ENG Bootloader? If we have a engineering Bootloader, why not just install TWRP?
2. Because the ENG Bootloader works on all SD variants, does it mean there is no real benefits of buying one variant over another, example, T-Mobile over Verizon, from a Root and development perspective?
3. Last I checked, we had a ton of issues with the ENG Bootloader... Lagginess, battery issues, lack of optimizations and no updates... Have these been solved? If so, how?
Thank you again and thanks to everyone else who may help too!

It's an eng kernel that is flashed so the bootloader remains untouched. The reason for the eng kernel is reg s7 kernels don't support root. As for the performance issues and battery drain most of the performance is taken care of with a few apps like lspeed. The battery drain is still rather heavy even using amplify and greenify the screen on time is still pretty poor the stand by drain is mostly taken care off tho.

Sorry, you're right Sir, the Eng kernel. Hmm... seems like still a pretty clunky solution for us Root (junkies?)
I just got excited when I saw the Echo ROM and people flashing through FlashFire. Also, I thought the U Firmware also allowed for some more flexibility? Basically allowing for any variant available to be used on any carrier and helped the Rooting case too?
Thanks again!

The U firmware has no very little bloat and has be used for the echoe rom for sprint carrier. It's a fairly long process to get echoe on sprint. But yeah I use the U firmware and I'm rooted on the latest firmware. It's a bit more of a pain to root the pl3 but I can't downgrade my Bootloader to an easier firmware. And your welcome it's np at all

Disable all these packages before flashing the eng kernel. And make sure to set ur apns after root u won't be able to see them but u can edit it still.

Root question about G930U

I recently purchased an unlocked S7 straight from Samsung
It's build is G930UUEU4APL2 running 6.0.1 and I haven't activated it yet.
Can this be rooted? And if so, do I activate it first with VZW or is it done prior to activation?
Not new to rooting, just new to this phone.. .so don't beat me up too badly.
There are multiple root threads for MM and now that N is finally out, you'll be able to update and root that. I would make sure it is activated with VZW and you test it out working first. Root can make the phone do weird things because of the engineering kernel not being designed for daily use. The root threads will also walk you through how to optimize the phone after root so that you don't run into too much lag. Again, use the phone unrooted for a short time to get a feel for it so you know what expected actions and results are

Best root method so far for Lag and Overheating?

This newb has rooted and unrooted several times. I apologize if this shouldnt be here but the similar threads were dated. I have an S7 edge SM-G935V on 6.0.1
Can anyone suggest which root and tune method(thread links please)lags and overheats the LEAST either on MM or Nougat. I only need root for one auto-clicker app and also require an Xposed module Security Bypasser, the only way Ive found to hide root so far the app I need it for. I havent tried any nougat roots yet because Im getting conflicting info on the ability to downgrade. Can anyone confirm this as well?
Also If I need to buy another phone, what is the smoothest running used phone to root for Verizon? If I cant get this working optimally. Pixel, HTC 10 etc... If Verizon isnt an option can you suggest a phone for Cricket or another carrier. I really need to get this working ASAP.
Thank you for your reply

Rooting s7 edge sm-935t 8.0

Hi I'm looking to root my TMobile s7 edge that's on Oreo. I see a lot of conflicting information and was wondering what everyone thinks the best method is and if there is a guide. I used to be into rooting devices many years ago but I've been away from it so long. Any help would be greatly appreciated thanks.
I am also looking to root my son's s7 edge. It's been years since I left Samsung for Nexus and pixel but I am assuming that you can still use Odin and install twrp then install magisk or whatever your perfered root method is. I am going to research this a little bit before I do anything.
There are methods but you would be stuck with laggy mobile as proper root is not possible... And for custom recovery its a big no, the reason is locked bootloader.
So no custom recovery means no custom Roms.. The root will be limited to run root supported apps. And lil bit of debloating.
But the lagging is not worth it.

Obviously we are serious. If you read my post I said I was going to research it further. This post was part of that research. Xda has a treasure trove of information and alot if it sometimes it takes a while to get what your looking for. Back in the day people on xda were happy to help. That's how I learned how to root phones and use adb commands.
