Hey man, easiest way is just to do a complete factory reset on your device (within the settings menu).. To be perfectly honest though, if youre planning to flash lollipop 5.1.1 on the device then just a quick heads up.. Firmware 5.0-5.1.1 seem to actually decrease the overall performance of the galaxy tab 2 10.1 GT P5100.. Not dramatically, but it is easily noticable to the trained/experienced eye/user.. Well for me it was/is noticable, but maybe im just use to all my devices all being fast. I cant stand slow/laggy/unresponsiveness..
Anyway, I have my Tab 2 10.1 GTP5100 with complete stock ROM 5.1.1 + Rooted. With all bloatware and pointless/useless apps all deleted aswell.. That helped a little with a slight increase in performance.. The battery life is actually pretty decent, i also do a lot of network streaming over my WiFi (stream videos from my storage devices, directly from shared folders from my PC etc, and files are anywhere from 100MB to 15GB and movies stream without any buffer issues)... If you also plan to root, its inportant that you remove all bloatware and try to keep your memory cache clean etc. Avoid installing battery saving apps as they drain the battery (duh) and dont bother with these bogus (virus scanners either) honestly ive tried them all in the past on many other devices and they actually do more harm than good by actually putting a (unnecessary burden) on the system.. Honestly, some might argue against it and recommend using a virus scanner on your device. But i can garuntee you, they are totally useless and a waste of system memory, resources(cpu,battery).. Keep it stock, keep it simple (downkoad only what you use all the time and/or what you need). Disable as many useless start up apps that shouldnt be auto started when device boots up.. Example (youtube) automatically starts the app and leaves it in the background taking up ram for no reason. Disable or set it to manual etc.. And most of all, keep the device clean from junk files.. Follow these steps and you will be a happy chap. Youll thank me later ..
**Oh and a quick side note, i recommend you enable developer options, scroll down to the "animation duration" and disable all animation options/speed. Aet them all to 0/off. That will increase/speed up device/app responsiveness and open/close speeds as well. 0 animation = pretty much insta load any app.. The only program/s i recommend you to use for system management are 3CToolbox and system app remover.. Especially with a rooted device.. You wknt regret it.
Anyway if you need help with any thing else. Let me know, and sorry for a long answe, i thought id just share with you as much as possible to make sure you have all the info you need

Lag Reduction Guide

Although I have none... Maybe these things as well as contributors can come up with some ideas that might have helped:
1. Kies restore via norbarb's/Kies method. This will remove root, but rerooting is 30 secs.
Root Link: http://forum.xda-developers.com/showthread.php?t=2252248
Kies Link: http://forum.xda-developers.com/showthread.php?t=2261232
All information is in his thread, but I feel it's easier to download Kies
start it up
and then plug your phone in. Kies will do the rest.
2. Seeder from Market by Entropy512. Root Required!
Download from Market
enable lag reduction
check only 'Start automatically on boot''
select performance profile "Moderate"
Reboot your phone and check its on.
3. Disable the following:
Power Saving (This one lags the phone quite a bit on different charge levels)
Screen Mirroring
Multi Window (This one straight lags the phone period, kinda useless)
4. Android Assitant
Download from Market
Select Tools from Tabs
Select Startup Manager
Under User Tab - Kill anything you don't care about
Under System Tab (Check to Kill on Startup, will run when you start it)-
Email (I don't use it)
Exchange Services (I don't use it - for MS Exchange Servers)
Help
Internet
Maps
Facebook SNS
Talk
Youtube
Reboot the phone
5. Developer Options. (Click 7 Times on the Build Number)
Window animation scale = 0.5
Transition animation scale = 0.5
Animator duration scale = 0.5
I don't use any ATT stuff so I removed it, but I doubt this will do anything. I have everything else enabled other than listed above like air gestures blah bla bla
By all means not exhaustive and lag is based on what you have loaded.... but I just hope this helps!
If others have anything to add please do.
0.5 still gives me lag, I set it to 0 just because it feels more instant.
I still see lag in glow animations, however, so I really think there is something up with the scaling/governor of the CPU/GPU. This will likely be remedied in future optimizations, patches, and/or third-party kernels (I hope).
I also turned off Air View, Air Gesture, Smart Stay, and Smart Scroll just because a part of me feels those were unnecessarily taxing. Messaging actually seems to load faster now that I don't think it needs to track finger movements.
I'm the opposite, I have all the features turned on & animations at default 1.
What I did was frooze all AT&T apps but left Samsung Apps alone since I like to see what they have to offer. Of course, you can freeze them if you want.
DL an app called Android tuner from the Play store & went to the startup section. I unchecked all apps that I didnt want to startup.
I have done just about everything listed in the 1st post and more at least 3 times in the past 3 days..
The lag-a-thon continues..
I have not tried Seeder or Android Assist nor will I!
I am sure they are premium and top notch applications but if I need to go to that extent just make what should be one of the fastest and quickest phones on the planet (based on it's specs) work then it's time for me to return and move along...
Good luck all as the POS is heading back to AT&T.. :good: :good: :good:

I believe you have to leave Samsung apps completely working because they are tied to the SystemUI and features.

I did the Odin method twice last night and once today..
Have not tried Kies but may give it a shot later tonight before this thing gets boxed up and sent back to hell...
I doubt there will be any difference whatsoever between using Kies or Odin but hey, I will give it a try..

Sorry about the frustration, but I appreciate you giving it another try as I really am enjoying this phone coming from an Infuse 4G.
In the meanwhile, try seeder and android assistant as well.... Root is reversible anyways.... Good luck!
Seeder is not by entropy512...it relies on a thing called entropy...and most devs say its pacebo as there is no real reason why it would increase performance...this is just based of the entropy threads ive read...and I believe entropy512 was one of those people who stated it was placebo so a little irony there...however if it makes your phone run faster then use it but I never noticed any differnce with using seeder on any of my previous phones (samsung infuse, htc vivid)

Its like any other program and settings done to phones. Some maybe affected some maybe not.... I through it on most my phones.... Depends what you are running I guess, but who knows... I have 2 SGS4's... One for me and my wife... She doesn't have it and I do.... Most settings are the same, i'll see... Both bought on opening date at the same time, so hard to tell hardware batch... But I will seee......
Try looking for an app that prevents apps from starting up like "android tuner" or "Rom toolbox pro".
Something else is hit power saver off and on. Power saver limits the cpu speed might be it...
sgh-i747(d2att)(sgs3) on latest cm10.1 or ultimatum
i've noticed a tiny bit of a delay when unlocking the phone and perhaps when opening SMS and the phone, but its not enough that I feel it's the same lag that a lot of people here are complaining about. I'm only basing that on the fact that there's no way i'd be THIS upset (as some of you are) based on what i'm seeing. So while there's lag, im afraid to try this stuff because it cant possibly be what you guys are experiencing unless you're all huge complainers, which I doubt :silly:
These steps can be done on any phone and are generic. I am suggesting you try it
Just a quick, simple suggestion for everyone posting their best "you should try app XYZ" on this thread and others without posting any links to them.... please take the extra 2 seconds to link the app from the Play Store - ahhh, you see what I did there! - because it makes your attempt at a helpful post actually helpful! In the thread I made about that Weather Station app, do you know how many apps that have the words "Weather Station" there are on the Play Store? Here's the current list - would be pretty mean of me if I didn't link it, right? And someone still asked me on that thread what the name of the developer was because they didn't just click the link! :silly:
My 2 cents........
I am rooted and have noticed a little bit of lag - In the past I have used an app called "LagFix" free https://play.google.com/store/apps/details?id=com.grilledmonkey.lagfix&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5ncmlsbGVkbW9ua2V5LmxhZ2ZpeCJd
So I tried installing it - dropped my animations in Settings/Developer Options to .5 and I noticed a pretty decent improvement.
I have also have always used Android Assistant https://play.google.com/store/search?q=android+assistant&c=apps because it is such a useful APP and it helps as well.
FYI - I also froze some of the unneeded ATT Bloatware APPS but I am not sure if that had any effect or not -
I was a little dissapointed when I first got this phone because of the lag but honestly I think I have been spoiled by running custom roms for so long I got used to having little to no bloat and hi power kernels --- so, I had to bring things into perspective - can't wait to get the bootloader unlocked and some AOSP roms to flash - lol
I still love this phone despite the few minor annoyances...
So i read in another thread of some people trying a different launcher and having better results.. I just installed nova launcher and bam.. lag is completely gone. LIke.. there is ZERO lag, not even a hitch.. so maybe the problem lies in how samsung did the launcher?
The only thing that i dont like now is that I can't use the really nicely redone clock/weather widget and the fantastic briefing widget which i fell in love with on day one. Oh well, at least my phone zips now.

Nice going to add to the front.
Some people are using Trickster to tweak the cores... which I have heard it works, but I get wakelocks from this,...
What kind of wakelocks are you seeing? I'm seeing very very little wakelocks using trickster. I unplugged my phone at 4:30 am this morning. 12 hours later I still have 89% battery left with very few wakelocks (kernel/partial). With 48 mins screen on. Couple of phone calls and texts.
Yeah not sure why.... I am not sure how to find these wake locks.... I would need to jump into Better battery stats to do so...

Extremely slow and laggy

So I got my Nvidia Shield a while back. The first thing I did when getting it was installing all the updates. Eventually after the final update was installed, I did a full factory reset of the device.
I have hardly any apps installed besides the essential Google applications, but my Nvidia Shield still feels remarkably slow. Chrome is practically unusable, and switching between apps is not a pleasant experience at all. That said, benchmarks and games perform wonderfully, which has me a bit puzzled. There doesnt seem to be any problems with memory leaks as there is plenty of RAM available. I do tend to restart it quite often just to see if it makes a difference, but I doesnt really feel like it has much of an impact.
Does anyone here have similar issues at all? I have worked with Android quite a bit and never have I experienced a system run Android so much worse than you would expect given the hardware specifications. My Nexus 10 feels a lot more snappy in general use.
Thanks for any help
All I can say is that I have a similar experience to you, although I have quite a lot of applications installed. I don't have any solutions for you, only to wait and hope that nvidia optimises the software for the hardware in the next update (Android 5.1 hopefully)
It's up to you, but I will recommend you to try this:
1) Unlock bootloader and Root (If you haven't).
2) Use CWM in this thread as custom recovery, I know TWRP is fancier but has some issues while flashing and wiping stuff, tending to not cleanly install things.
3) Try @BitOBSessiOn custom CM12 ROM here.
4) As stated there, avoid CM gapps, we don't know why but they are culprit of making the system lag A LOT making it almost unusable as you posted, specially if you frequently use Facebook and Chrome. Instead use the minimal gapps posted there.
5) Really important step: Activate Developer Options and disable all animations, lollipop men leak resides on a function called when the system draws them, so the only temporal fix for this is disabling them, after that, reboot and kill any bloatware app on options > apps (G+, FB, Messenger, Vine, Chrome, etc)
6) Profit
I've had this problem too.
I just turned off battery saver. It got too low, automatically turned on and I didn't realize but when I turned it off, it got way faster.

The Lollipop memleak bug is pretty easy to detect though and that's not what's causing the performance issue on the Shield Tablet. At least not in my case. While I would normally be the first to unlock my bootloader and port CM to my new device, I would want to keep my tablet stock.
Im glad to know I'm not the only one experiencing issues so Im going to assume that there's nothing specifically wrong with my device in particular. I guess Ill give Nvidia one more chance to rectify performance issues with their next update, otherwise I'm selling the tablet and buying a Nexus 9 or something else.
I have the same experience. I have flashed the latest recovery image, unlocked and rooted. I have disabled apps I don't need and does not have a lot of apps installed. It is unbelievable slow. Like stated above Chrome is almost useless and switching apps is painful. I am using my Nexus 10 too, the Shield tablet will collect dust until there is a fix released.
If I have the time I will try flashing CM12 but I rather stay stock.
You should give it a shot...
Chrome lag totally solved. Most Nvidia apps work. Only deal breaker is the controller, but a ps3 controller can be paired via BT using sixaxis app.

This has almost convinced me to switch to cm12.
If it just werent for the loss of Dabbler, some other Nvidia apps and the fact that I have a looooot of apps installed...
Not worried about gamepad, because I use an ipega 9023.
I may have found the holy grail of slow laggy freezy hell! https://play.google.com/store/apps/details?id=com.jrummy.apps.memory.manager under tasks go to 3 dot menu at top right choose minfree manager pick the top silder and max it out. Hit apply, let app stay in background and proceed with speedy happy days.
I don't know why but it won't keep the settings after boot no matter what I do but I can live with it now and don't fantasize about smashing it with a rock anymore.
I should mention short of non-stock Nvidia roms I tried EVERYTHING twice! This just works for 3 days now perfectly. I actually might even trust it in a week for actual work applications. My poor old Nexus 7 gen one was totally owning the Shield except for game until now.
I have a LTE USA model running rooted 4.4 Kit Kat. I would guess this will work with 5 as well.
Please remove. (Double post)

Root your tab. Do a nandroid backup, backup your apps with titanium backup, flash cm or team eos rom (gotta plug my stuff, restore your apps with titanium. If you don't like it, restore your nandroid and you're back like nothing ever happened.

Dabbler works fine on CM. It's on the Play Store.

And GRID also works fine. The only deal breakers (and the ones every dev is working hard to make em work on AOSP) are console mode and the controller wireless pairing.

That's contradictory. I have a really tiny LMK value for foreground apps (foreground= 8mb, Visible=16, secondary=32, hidden=64, content provider=96, empty=128 ) so apps in the foreground are killed only if system goes under 8mb of free ram, and have no lag, but I'm on CM12.1. So I really don't know how this is working but I'm glad for you. Although it may drain your battery faster BC android is killing apps as soon as they go to the foreground to keep that amount of free ram and is using more CPU cycles to load them back when you need them again, that's what I get. But anyone with more knowledge maybe could guide us why this is working???
Interesting, it's working but I didn't even try any other variables. I will try your settings and get back. Needless to say battery life is next after usability.
---------- Post added at 07:01 AM ---------- Previous post was at 06:28 AM ----------
Ok tried your suggestion verbatim. It immediately was back in useless mode as I have been calling it. Without a reboot it took me at least 15min to get back to here. Still could not type so minmanged back to previous settings and its running. Weird.
My test would have been run Facebook, chrome & this app with poweramp music. Never got halfway before it got all James May on me. Are we running the same tablet? Any thoughts on why we could have opposed settings and get different successful results.
---------- Post added at 07:02 AM ---------- Previous post was at 07:01 AM ----------
Also when it slows down it gets warmer the settings I'm using leave it pretty cool in comparison.
I'm on stock 5.0.1, 32gb SD + internal memory almost full. I experience some lag mainly with chrome and switching app. Yestetday I tried to set the power saver to "max performance" and the everything seems much smoother..
Make sure you SD cards are formatted with NTFS. exFAT is fine for 32gb, but if you have a 64GB or higher, the card needs to be formatted in a PC using NTFS...
Don't ever let your main ram storage memory get below 500meg.
If somehow you run out of memory,, let's say sub 10megs then all manner of weird things begin to happen including reboots and app crashing. You can jam that external sd1 card full however.
I reset mine several times and tried everything I saw in these threads about the lagginess and stuff.
In the end, I found the solution. I returned the NST and exchanged it for a new iPad Mini 2 32gb Retina Screen... No really.
I love Android on the phone, but it just seems that the tablet arena isn't anywhere near as far along and sorted out yet. Buggy, almost too many options, so you wonder how much love each model gets from the manufacturer, etc... I hate to have a new tablet for $300, and the only way to get it to run the way it was supposed to run out of the box, is to void the warranty, root and install a custom ROM on it, and give up some features in the process.
I like ROMs for things that they do above and beyond the stock experience. I don't feel that I should pay that much for a device and have a ROM be a requirement just to get it to run decently...
So, for my tablet needs, I had to go to the dark side. Good luck!
I will still rock my Note 4 and don't see myself going to Apple for my phone needs any time soon, but for a general purpose tablet for Netflix, email, browsing and basic games... I agonized for hours over this but in the end I just pulled the trigger and exchanged it.

You Root Your Phone for What?

Many people may be ask what is root? Surely most of you know there is an account called administrator in WINDOWS XP and it gets the highest permission to operate the system. Then, Root is to cell phones what administrator is to computer. Only after you root your phone can you have the permission to customize your phone.
Then can you share your root experience. I am considering whether to root my samsung phone.
Ahh for so many reasons. But to name a few: get rid of bloatware, block ads, listen youtube in the background, record my screen, most importantly customize your phone the way you like it and many many more
For more custom features and to make my phone more smoother. My stock rom was really freezy and laggy. When I rooted my phone and downloaded a new rom, my phone feels a lot more smoother.
Mainly for customization and for remove ads u.u

No wonder so many people want to root their phone.
To remove ADS, definitely. I understand the value of them, but I can't stand them...

Install a custom ROM and you'll see why.
Rooting gives privilege , if you are not satisfies with what you have , default apps , any other think which can be modified only if rooted .Although i you wont be having company warranty anymore.
I saw this great reddit comment that summed me up pretty well; for a while I did the whole root thing. Loved it. Tweaking every tiny detail of a phone, getting access to insanely powerful apps, etc.
But it all started souring. Confession: I'm a convert from Linux and Windows to Mac. And that's because Mac's just work for me; when I'm needing to do something vital, I'd much rather something that is 50% less powerful but 100% stable. And I've found with my Galaxy Note 4, although I am annoyed at Touchwiz, at a lot of the stock touches, I much prefer having a non-rooted phone that, if/when an error happens, I know is nothing to do with me.
"My evolution using Android..

become flashaholic flashing multiple ROMs per day crack flashing.
Never having the same ROM/setup for two days in a row
Want more power....

OVERCLOCK!!
Too much battery being used
OVERCLOCK! UNDERVOLT!
Now horsepower is not so important.. Need more battery life...
UNDERCLOCK!!
Need to squeeze more battery life out of device
UNDERCLOCK!! UNDERVOLT!!!
Tired of custom kernel stability(even when not OC/UC UV)
Stock kernel... custom ROM, rooted..
Tired of all the bugs and little nuisances in custom ROMS..
Stock rom, stock kernel... still rooted of course
Root? I don't need root anymore..
Completely bone stock
The end..."
I root my device to get rid of bloatware, to install custom roms, to customize my device the way I want.
For best battery life.
- Remove bloat/spy/adware
- Titanium backup for easily migrating apps+data (including system apps) to other devices
- Micro-manage permissions of apps for security and efficiency.
- A good proxy/VPN app (if you've been to China you know what I mean).
- Killer youtube replacement app (downloads, plays in background, checks other video services, etc)
- Screen rec. app (pre-lollipop)
- Adaway (blocks adds even in games)
- Tasker
- Possibly to re-partition the eMMC --typically with those cheap 8GB devices that emulate an SD card and only have 1GB or so for apps. But that can be tricky. Would preferably try to flash a custom ROM/Recovery if possible, which is not really related to root.
- Also didn't add nandroid backups to the list because I don't tend to flash custom ROMs much.
I rooted my Samsung as soon as I got it in order to get rid of the unnecessary apps and save the ROM space. Enjoy my customized phone since I don't like the feeling being led by the rose.
I root my devices to use them to their highest potential and of course for Flashing various ROMS and Kernels

Ive unlocked my device's bootloaders, rooted them all.. And i can honestly say, i dont regret it at all. Ive debloated the phone completely, ive even removed core system apps and services that i dont need or use.. I removed everything related to nfc (the NFC chip is actually used as a tracking device and stuff). Im very pedantic when it comes to blocking anything with hidden permissions and blocking apps from having open unrestricted access to my files, location, info etc etc.. My firmware is. Very clean, to give you an idea of how much ram and storage space i freed up.. Before debloating my phone and cleaning out unnecessary system apps from my device.. The the system was using up anywhere from 2.2-2.7GB RAM... Thats extremely high considering thats more than 75% of your total ram..
After debloating my device..
System only uses 1.4-1.7GB RAM..
And to put the icing on the cake. The battery now lasts aaaaages even when playing games and doing a lot of heavy use., the phone barely even gets warm as well. Which is an added bonus.. When my phone is in sleep / doze state (screen off) my device has lastest up to almost 10hrs with only 1% battery left ... Loll
But if youre worried about voiding warranty, then just gotta be patient and wait for an exploited firmware with rootable system.
I suspect it wont be too long of a wait

Hey,
Would you mind telling us what apps/core apps did you remove?

Certainly
Removed The Following from device.. on a (Rooted Xperia Z5, Unlocked Bootloader)
----------------------
Browser (small app) --- (this app is so useless, it just doesn't belong)
Explore (Sony) ---- (Not interested)
Facebook ---- (I dont use facebook)
Linked in ---- (Dont use / need it)
Playstation App ---- (Dont need / use it)
Account Manager (Sony) ---- (Useless, Not needed)
Creative Effect --- (I Dont bother with camera effects and photo editing, i just take photos as they are)
Drive --- (Google, Again- I Dont need / use it.. cloud storage on google.. no thanks!)
File Commander ---(Don't like it) (I use ESFileExplorer instead)
Google Lyrics Extension --- (Like seriously, Wtf is the point of this useless app) its legit, useless. haha..)
Google Play Books ---(Dont need/use it.. pointless app, waste of space/ram)
Google Play Games --- (I dont sign in with my information to play games) (Problematic App, Just delete it) even after deleting it i play every game fine, without any problems.. (Safe to get rid of it)
Google Play Movies --- (AGAIN, unwanted bloatware, Who The. **** would even consider using this, pay to watch movies, HAHA yeah right!)
Google Play Music --- (Yet AGAIN, unwanted useless bloatware, when i can use Youtube/TubeMate instead)
Google Play Newsstand --- (GET OFF MY DEVICE, Extremely Useless bloatware AGAIN.) I hate anything google relation UNLESS it's needed (Play store, Play services, like thats fair enough)
Google+ ------(Hell no, GONE.. I dont need it and dont want it, To me it is considered BLOATWARE) most google related APPS also ask for unrestricted / Excluse access to your entire device.. Like wtf.. NO thanks!
Hangout ------(bye bye bloatware)
Movie Creator ------( Dont need / use it ) simple video recording is plenty for my use..
News & Weather ------( Don't Want it on my device, When i can simple check everywhere else with consuming ram / space) drains battery aswell.
Photos ------(Dont need it, WHy would i use it when I have an App called ALBUM that works good enough) (And I'm not in to the whole photo sharing/social crap that goes along with it.. (Bloatware in my eyes)
Playstation Video ------(Dont use / Need it)
*****ALSO, I removed the default theme Colors that i did not like/want.. I kept Dark & Red.. I deleted the rest though "Orange, Purple, Blue, Green, White" each one was 8MB .. (Dont need things on my device that i wont be using, Right?? ****
Socialife ------( Blah blah blah, Gone!!!)
Sound Photo ------(ahhh yeaaah--nahhhhh) useless to me.. Considered bloatware.
TalkBack ------( Gone )
Video------- (Unwanted Bloatware)
Weather Widget -------(No Thanks, As small as this app Appears to be) It is a god damn battery killer.. Thats A fact!!!! Location>
And that should pretty much be it for now, unless i have missed anything..
Hope that was enough info for you mate ..
Then,
A few others i removed, are a few pointless key modules as well (mainly camera related)
(Lips, sunshine etc) these modules are obvious to spot.. Their icons are of little smiley faces each module with a different color smiley face.. Get rid of all the ones you dont need / want..
Also remember to always restart your device when disabling / force stopping / deleting apps/services / modules / core services etc so that any remaining residual files are removed completely and the new (device spring clean) takes effect.
So restart once you have removed everything you dont want or need..
FYI, removing some of the bloatware resulted in reproducible 'random' restarts on LP.

TheTecXpert or any of the others, forgive me for my ignorance or stupidity lol, but rather new to playing with my phone, I have always rooted my Sony's mainly for custom roms to get extra options etc, but now looking to expand my horizons.
I'm not a complete newly to programming (have done my share 13 years ago) lol but also have a fairly I.T knowledgeable background.
Are you able to explain or advise or point to another thread that explains how you removed all the excess system apps etc (yes I have looked but usually at work with limited Time)
Hey man,
Don't worry about your warranty ! It's not a problem voiding it as soon as you know how to repair a bootloop or those sortr of things. It will (of course) won't void your technical warranty and, trust me, it worth it (see @TheTecXpert , he done a lot of great things )
Of course this is your choice to wait. It's a good solution too, but rooting is very cool on Android. Think twice
Hi cab13,
Z5 is already running mm, flashed it and now rooted and bl unlocked so not concerned about warranty. I have found it near impossible to brick these things lol, just not sure how to remove all the apps that TheTecXpert did, Wether it was done with programming or something as simple as root Explorer(if so what directory)

Hey, I usually just use ADB to get rid of apps I don't want/need. The ADB shell commands are very similar to *nix commands.

The simplest way that I went about removing all the excessive apps/bloatware was by using a program from the google play store called "System App Safe Remover" or "System App Uninstaller", anything that gives you direct access to ROOT SYSTEM APPS.. You can use ADB, for but for those not completely technically savvy in the "Command Shell" I would highly recommend not using ADB..
Anyway, Once you launch the APP (of your choice) , you will be in a menu with ALL APPS that you can remove.. they will be in categories and alphabetical order.. the App will specif things like "could remove", "should keep", "Key Module" etc etc...
From there you can just uninstall all the crap that is not need and anything else you dont want.. In an earlier post I have a long list of APPS and modules that I removed from my phone which gave me an OVERALL stable, clean, fast and Battery Life improvement on the device.. I'm happy with it.. And Warranty is never an Issue for me since i've always rooted ALL of my Sony Xperia devices and have never had any issues with them..
But everyone is different and has their own preferences on how they do things ..

Samsung Galaxy always becomes slow and laggy

Hey guys
i need some tips or feedbacks. So ive been with the Galaxy since the S3, and each one ends up becoming the same. They are great when i first get them, then within the first 2 months, they pretty much turn into crap. The UI isnt smooth, things take a while to open, apps dont transition to another smoothly, opening texts,, going back and forth between texts and apps arent the best and i constantly get problems to the point i need to do a warranty exchange with tmobile.
Do you guys experience the same or are you phones super fast and fluid? Even with a rooted phone i experience the same. Whenever i test out my friends iphone, everything seems to be super quick and fluid, just not customizable and limited to what you can do
What can i do to improve my phone or this is just how these galaxies are?
Thanks!
Hiya
I find it's good to reboot every so often, and I also use the built in Smart Manager to Clean All, and I don't experience any lag.
I do run my phone pretty clean though and don't have a million useless Apps which does tend to slow it down.
Reboot and use the smart manager from time to time and you should be good to go. I also find that using Package Disabler, Nova Launcher and Anti virus Apps SLOW DOWN my phone and make it buggy and laggy.
I have now wiped it and left it fully stock and it multi tasks properly and is super quick.

Thanks for your response. i already do all that. I use clean master everyday to clear my phone of cache and boost it so all background running apps are closed. when rooted, i deleted all useless apps and bloatware. i do restart my phone but still, i face these problems. its just frustrating when using an iphone because everything is so fast! i just want to fix up my android to be the same but it always turns to ****. im now facing a problem where outgoing texts stays stuck on sending and doesnt go through so now i have to use a third party messaging app.

Seriously, cleanmaster?? Delete immediately! If you're rooted, why don't you freeze the bloats? Use amplify and greenify combo! Can't believe a rooted user uses cleanmaster
Clearing cache every time is not good and results in stutters as cache is meant to make loading times faster and usually only cleaned if there are signs of corruption!

lol i didnt know about that for cleanmaster, im new to the whole rooting thing so i didnt know. i already freeze the bloats using titanium backup. also, i had to update my phone because my call quality was all messed up. i updated my phone to baseband version DOJC. upon doing that, my phone is no longer rooted. where are the best places to go to download new files in order to root my phone again. i dont want to use my old files and risk messing up my phone.
Thanks

So if you're no longer rooted, you can't use titanium backup. No need to root the S6 as you won't be able to update and rooting without using custom roms isn't that great.
Use package disabler pro! It's enough. Put apps to always optimize in battery settings. Use a custom launcher like Apex or Nova. Update everything. Clear cache in storage menu and reboot. You should be good.
Try leaving at least 1GB out of your internal memory free, although its impact is not proved!

no, i meant i used titanium backup when i was rooted. im no longer rooted because i had to update my phone in order to fix some problems i was having. When i was rooted, i used a custom rom, twisted sixx version 3. i want to reroot my phone again, but i want to know if i need to download new files again to root if what i used last time is ok. last time i rooted was in septempber so my files are from that time frame. If not ok, where can i go to get the new files i need to root again? also with your phone, is everything usually fast and fluid or do you come across the problems i mention earlier as well?
thanks

Sorry can't help with newer root methods!
I'm completely stock and using package disabler pro and app optimizer. It's not buttery smooth like a Nexus or Motorola, but it still is a fast experience, i.e, rarely any scrolling stutters. Try putting animations to 0.5x or 0/off.

ok cool. i just installed it, looks to be the same like the titanium backup where i can disable freeze all the random apps. any idea why my texts are stuck on sending? dont really want to do a system wipe to see if that fixes it

Np! Try defrosting some packages that as per your guess might be linked to the sms system.
Try sending through a 3rd party app like Google messaging app on play store and see if it works.

Or he could use Kernel Adiutor and set Androids build in kill scheduler to free ram

My little tips :
First. Speed up your android device by *not* installing any speed booster app.
2. Android is smart enough to force close background services when more ram is needed. And restart them when ram hungry process (e.g heavy game) ends. Do some research, it's a very very bad idea to manually kill background apps and services. Doing so will just decrease both your performance and battery.
3.Stock Samsung provided applications gives better performance and battery life. They also use ram more efficiently. try using stock launcher,stock keyboard, stock E-mail app, etc.
Also every other launcher that uses vertical scrolling will have lags. (Apex,Action,Nova and even Google Now Launcher)
4. Manually clearing cache is also bad idea. Imagine you put your charger on your desk to quickly access it when needed (cache), then someone puts it back to drawer every time :| (Clearing catche)

Thanks for the tips. i already use stock email, stock interenet stock everything. My battery dies extremely quick with minimal use, as oppose to when i had it rooted, which was significantly better. with minimal use today, its been off the charger for 5 hours and im already at 50%. i also dont force close. i just click that menu button and press close all when nothings being used, or are you saying thats not good to do?
i have mine for 10 months, and i don't regret it at all, i had a galaxy S2 and S4 before and i always said i won't get another samsung because of the lag, but this time i made the right choice...the phone flies through everything, loading apps takes no time, opening apps really fast, the truth is this is the first galaxy that didn't lag after a couple of months, at least not for me, there are sometimes some frame drops, but in general it's really fast, i use stock apps, i restart my phone about every week, the battery isn't that good, 3-4 SOT...so not bad but not that good, because this is a phone you wanna keep using all the time and then suddenly the battery die.....the truth is if i had the money now i would get the NOTE5/ S6 EDGE PLUS...because of the battery and big screen, other than that it's perfect....best screen, camera, the new TW is really good....
