What apps (rom stock 4.4.2) i could freeze on start to better performance ?

Please, I'm a little unsure to install TWRP because I'm on android 4.4.2 (with root) but I'm seeing several people with problems after installing.
So I ask (for those who understand the subject): I will stay with the Stock ROM for now, could show me which apps I can freeze on start, and improve system performance?

Get one of the Root Uninstallers and *don't* uninstall any green icon app if your not sure of what it does. Also try and not completely uninstall - but put the apps you discard in the trash so you 'can' retrieve them. In other words - say your not going to be editing movies, uninstall it to the trash, etc. That's one way.

[Q] General inquiries: Firmware, Knox, Debloating..

Hi all
I just got my 8.4 Tab Pro and need some advice before I apply my usual tweaking. Sorry if something similar has been discussed in other threads, I was not able to find definite answers to my questions.
As with all my Android devices I'd like customize the Tab Pro to minimize load, remove bloat and basically have the most control over it as possible.
- I rooted the Tab Pro with Towel without triggering Knox. So far so good. From what I read though, installing a recovery mod and/or a custom rom, Knox will still be triggered. What if I use an 'optimized' (debloated, tweaked) stock rom, is there a way no to have Knox in the way?
- If there's no way to prevent Knox from triggering: Any advice on which processes/apps can be safely removed and which (eg build.prop) tweaks would make sense for this device?
- Is there an overview which shows available Firmwares and maybe even changelogs? I'm a bit confused by all the different available codes and their corresponding origin countries.
That's it for the moment, thanks in advance

as soon as you flash a custom recovery, you will trip Knox. There is no way around that at the moment.
you can freeze quite a bit of the stock apps to get the device to run smoother. check your settings -- apps, and go to the running tab. Note which apps you don't use that are running in the background, and then freeze them with Titanium backup or similar program. Note some apps have multiple APK's that need to be frozen.

Hah, looks like my Auto-Correct trolled me with "Knox", nice one :silly:
Corrected it..
Thanks for the reply, that cleared it up for me with the trigger.
Regarding the other topic though: I'm aware how one can identify and disable unnecessary apps, I was hoping to find (for example) some kind of a list like the one Rom Cleaner uses where stock Samsung bloatware is identified- which would make it a lot easier to work on with the ridiculous amount of stuff included in the device.

Not sure if there is such an app yet for the tab pro..
I made a list of apps I froze in the battery life thread, here's a link to the post:
http://forum.xda-developers.com/showpost.php?p=54229116&postcount=26
Keep in mind, I started off with a rom without the All-Share APK's, and without the Knox APK's (there are several of each).
since that post, I have also frozen S-finder and Security Manager Service. Started getting random reboots, so I re-installed Security Manager Service, and it seems to have fixed the reboots.

Nice, thanks for that- that'll be a good start.
Any ideas regarding the different available firmwares?

I'm on ND3, which seems to work for me. Using Freeza's nearly stock rom for now and all seems well. haven't tried any of the CM based roms on this tablet yet though.

Talk me into rooting.

I have a rooted s4 from Samsung. But I have a nagging feeling that rooting this with an update to Android L, I will miss something.

Nope, no reason to root. Stay where you are and don't move.

What's my motivation?
Recovery, roms, kernels, Titanium Backup.
Sent from my SM-T700

1. Write to SD card fix
2. Debloat/freeze unnecessary apps (saves space, ram, and battery)
3. Xposed Framework
a. Boot Manager
b. Wanam Xposed (fairly decent customization)
c. Youtube ad-away
d. Pandora patcher (awesome features)
e. Minminlock
f. Greenify
4. Custom recovery (scheduled backups)
Android L might take a while until officially released for Touchwiz devices. If this devs keep doing the great job that they are doing, a custom rom running a variant of Android L might show up faster.
I was not inclined to root at first and void my warranty, but I love this tablet and these additional features are must haves for me. Do whatever is best for your needs in the device.

For all the newbs out there can you (explain in detail) the benefits of all those features, for newly rooted users. Thanks [emoji106]

Sure...
1. Write to SD card fix => I download a fair amount from torrent sites, I can now save files directly to SD card instead of taking another step to copy and move them over then delete them from internal storage. I believe as stock only certain apps can write to SD card, now any app can potentially do so. Like I prefer ES File Manager as my default file manager as opposed to the Samsung My Files app. It was crippled without this fix.
2. Debloat/freeze unnecessary apps (saves space, ram, and battery) => Delete bloatware apps that you don't use which you can't do without rooting. NYTimes/Papergarden/Milk...I don't use them, so don't take up space on my limited storage.
3. Xposed Framework
a. Boot Manager => Choose which files you want or don't want at start up to improve boot time.
b. Wanam Xposed (fairly decent customization) => From status bar tweaks (colors/icons/clock), 4 way reboot options, auto expand volume panel, these little tweaks here and there that you can't get from stock make using this tablet so much better.
c. Youtube ad-away => As a heavy youtube user....NO MORE ADS!
d. Pandora patcher (awesome features) => Unlimited skips and even downloading thumbed up songs!
e. Minminlock => Remove ads from certain apps.
f. Greenify => See which apps are eating your battery and freeze those apps.
4. Custom recovery (scheduled backups) => Up to date backups in case something goes wrong. I recently had some weird bug with the Play Store where I couldn't update any apps and there was no fix I could find online. Simple flash of latest backup got me running 100% with minimal effort.
These are just my personal uses for rooting my device. Everyone has their own preferences, let me know if this helps.

Perfect summary. Not much to add!

So what's the risk then?
I'm loving the Tab S, but not being able to use Xposed and TiBU is driving me mental.
Should I root it? So far as I understand, it'll trip Knox, which means that if my tab breaks in some way, it won't be covered by the warranty anymore - is this correct?
Should I do it anyway, or maybe wait a while longer to see if someone comes up with a way to root without tripping Knox, ot to undo the Know trip counter?

Update when rooted?
Hi guys/gals,
just got this tablet (t700). If I do root, will I be able to get the next update OTA or using kies? I can appreciate this might be a difficult question as the next update obviously hasn't come out.
Thanks in advance.

you can still get OTAs if you use triangle away...if it works on the Tab S that is.
I've had Android devices for years and I still don't understand why people still want to get OTAs while rooted, that same OTA will be out within a day or two on the forums, usually with knox removed and root injected. So it just makes it easier on you if you forget all about OTAs.

Loss of warranty of a $500 plus device is a good enough reason for me not to do it. Those few benefits do not outweigh the potential downside.

How were you able to get Pandora Patcher to run properly on the Tab S? I rooted my tablet for this and Titanium Backup. Pandora Patcher doesn't want to work on my tablet. I even updated to the latest PP (v3.5) and Pandora (v5.5) but it still doesn't work.

[Q] Sprint Note 2 rootted stock now an update nag

Device Info: Sprint Galaxy Note 2 Running rooted stock Android 4.4.2. (chainfire auto root using odin)
Wifi only unit. I have no sprint contract purchased it used (I'm new to customizing android- I have flashed an old palm pda, but only via guidance)
Situation: Rooted the unit and have customized it as mine
1. No custom backup and would like to do that
2. Do not like all the bloatware apps
3. Now a system update has been downloaded asking to install (I've not okayed it)
So please help me with each of these
1. Please point me in the direction of best way to take a backup of existing rom ( I do have philz downloaded, but I'm not sure about how to ?
2. Would that deal with the persistent update request? Would it be good to update?
3. and then the bloatware removal, should I use an app that removes system apps? ( I have titanium, but I'm not good at knowing which apps to touch and not to touch) Thanks in advance and no I'm not in a hurry as yet.

Hi,
I will have your thread moved to your device section so the experts who own your device can help you.
Good luck!

Point to links please
If someone doesn't want to tackle this whole question I'd just appreciate links on how to step by step. I'd appreciate any help at all, I'm just a bit fearful of bricking the device, but if the instructions are clear I can definitely do this.
The first is issue is backup that is my priority at the moment. The second is whether to install the update or not and how to get rid of the nag. thanks

Not sure about backing up the ROM itself... but what I do is just back up the apps with Titanium and then re-load the apps (or just data) when I have to re-install my ROM like I did a couple of weeks ago. Prior to the Note II, I had an HTC Hero (stop laughing) and would do nandroids for that device. Don't know that you need that for Samsung devices, but somebody may be better to explain than I am.
ETA: here's an article on creating a nandroid, FWIW
http://www.makeuseof.com/tag/what-is-a-nandroid-backup-and-how-exactly-does-it-work/
If you are rooted, I don't know that the persistent update will actually apply/install. I'm on Classic Stock 4.4.2 and I also had the same nag. Here's a link on how to disable the update nag. This is what I did, as my phone would not apply the update so I just disabled the persistent reminder using the steps below.
http://forum.xda-developers.com/showthread.php?t=2442207
With respect to removing system apps, not sure I can offer much direction other than to suggest removing obvious apps (maybe like the Sprint Zone app) and then just doing a search on each app that looks like you can/want to delete or uninstall. Probably a bit time consuming, however, I am not aware of a "bloatware list" or anything which outlines safe-to-remove apps.

Much appreciated Lenny
When I did the root, I didn't really want a custom rom, just stock with root. Now that I've used titanium backup and have removed the install update nag- I'm set for a while!

You might also look at adding a free version of BusyBox (I use stericson's, and jrummy also has one out there).
Also might want to look at an install of AdAway, which you'll need to install manually (not available from the Play Store). You don't have to install the whole F-Droid package, you can download only the AdAway apk if you want.
https://f-droid.org/repository/browse/?fdid=org.adaway
One last piece of info, you may want to turn off automatic updating for apps, as the SuperSU app can have problems after an update and you might have to re-root your phone. Here's what I ran into.

Thank you! I've side loaded adb adblock is adaway better? I use App Ops to turn off specific things within each app such as location finding, I like MW apps manager to add more apps to the multiwindow feature., and I've turned off most apps auto update, but some apps I've left auto update. I've just turned off auto update on super user -- even though, I've not yet experienced any major issues as yet.

Don't know if adb adblock is better - I've never used it. Didn't see you mention a couple of these things when you said you were "all set for awhile", so I was just trying to offer a few other things to consider and look into. Sounds like you're already on the ball though!
Personally, I'm happy with stock. Big reason for me to root was getting rid of ads. I've tried some of the other ROMs but I've always come back to the stock look and feel. I've had the device since about 1 week after it came out in Fall 2012. Of course, I am also on my third one since I totaled two other ones. I absolutely love it, and am in no hurry to upgrade (if possible). Hope you enjoy it as I have... lots of good stuff from devs here!

Tabs S changes.

Hi all,
I hope this is the right to post.
I am at the point of throwing my SM-T800 in the bin. This Samsung bloatware is getting beyond a joke.
I have been toying with the idea of putting a custom ROM on it just so that I can get rid of all this Samsung crap.
Do I need to go that far or can I just put a rootkit on the tablet or maybe there is some other way to achieve my goal.
At the moment I’m just looking for ideas. Anything that could help would be appreciated.
Cheers,
Graeme.

I haven't had much of problem with this. One way to get rid of Samsung bloatware, is to go into settings > applications. Go through the list of every app. If you have no use for it, then delete it. If there is no delete option, like with flipboard or "internet", then disable it. This will stop all of its apps services and also will uninstall all of this apps' updates from the storage. Of course, the tablet will not become exactly "fast" after this because Exynos 5 Octa 5420 was a modest SoC, specially when coupled with the QHD screen. However, freeing up some space will be appreciated on the 16GB storage models.
PS: if there is no delete or disable option, click on the storage and at least delete cache and data. At least this will free some storage.

Hi Akopps
I think I may have not made my goal clear.
My aim is to get rid of any unnecessary Samsung software for no other reason than not having them tell me what I can and cannot do with my device. I have owned it for more than 3 years now and it is well out of warranty. I am happy with the performance. It meet my needs. Disabling their software and removing latest updates just seems a bit futile. Samsungs' "Kids Mode" app just updates itself and then wants to take control of what you see. I'm in my early sixties, no young children or grandchildren and with no need for "Nanny" Samsung to tell me what to do.
I just want to get rid of there "preloaded" software. After all, I own the device, why shouldn't I be able to remove the software?
Cheers,
Graeme

I have tried the same but was unable to use any of the how to.

I'd prefer something like system app remover or BK package disabler in case something is inadvertently removed that causes an issue. It can easily be restored.

Hi guys,
do you have a personal safe-to-remove apps list?
I've tryed following the ones already discussed in this forum section aswell as others but I've encountered some freezes/reboots. (For example by removing BBCAgent , BeaconManager and Context Service).
Thanks for your time and happy new year! (tab s still going strong after 3.5 years yay)

Tonyspo is mostly correct. Flash TWRP using odin, boot into TWRP, flash superSU. However, if you're only goal is to remove preloaded apps, I'd suggest taking ashyx's advice and just install BL package disabler from the app store. I use that on my Galaxy S7 and it works great.

I've tried odin, but in download Mode all of my PC's won't recognize the tablet. When booted everything is fine (but than I can't flash)
I've read its because Samsung removed the Option in the Rom to get root rights.
I've also tried Heimdall and I only get error msgs.

I guessing you're actually in recovery mode not download mode if the tablet is recognised when booted to the os.

It says it is the Download Mode
pretty sure it is the correct one
