Installing applications slows down the device!?

I am noticing after I installed a number of games and some apps from the market shows that the smooth movements during swipes changes to a bit of stutters.
Mainly I am noticing this in the home screen when I wipe to scroll through the number of home screens it was not smooth as before-i can spot minor stutters, not smooth as cake!
Is it only me or this can be overcome?

That's what I found too.

This is what I found too.
From my observation, I am thinking that a lot of Android's applications on the market are:
1. poor quality with very little QC by Google. Google may be too focus on releasing as much application as possible to catch up with iphone rather than quality.
2. request too much permissions from the user, such as full internet access, running in the background etc etc. A lot of applications that don't necessary need these permissions are asking for it anyway and I don't know why they needed it.
3. this last point is my PURE speculation, so do correct me if I am wrong. Most applications are ad-support, they needed to download ads to show on your phone. That means each application on your phone that are ad-supported need to connect to a server somewhere. I don't know how google manages ads, but I sure hope that it doesn't allows these applications to connect to different ads server in the background.

i found this slightly too, doesnt the new firmware updates (unofficial) and the lag fix (putting the apps in the nand) fix this though?
im still waiting for samsung to give me the update, wont be waiting much longer though

I think you just wrote the last sentence in a confusing manner. I think your point is "I sure hope it doesn't allow these applications to connect to ad servers in the background", if so I'm with you.
However, if you mean it the way I interpreted the more direct writing of the post. (disclaimer: I also don't know how they handle ads), but I think that more than just admob exists as a service for developers to use, and if that's the case and they do allow any connection in the background...then I think some would have to connect to different servers since the ads would be hosted by different hosting services (admob, company x, company y). All that said, Admob does (just about?) every ad I see that I happen to look at the host of.

I experience 0 lag during homescreen scrolling.
I use LauncherPRO, in advanced settings I have "High quality scrolling" enabled (Keeps high quality graphics while scrolling, but reduces performance) and then in Advanced Settings subsection "memory usage present" I have "Use homescreen caches" (creates caches of your homescreens for smoother scrolling" checked. I have over 150 programs. 7 homescreens, though 2 are at least half blank, but I have 5 rows of icons on each screen (20% more icons to slow me down).
LauncherPRO typically uses up 20-25MB of memory for me due to my settings. If you don't have it, check it out. If you have it, look into your settings to optimize performance.

[Q] Going after minimalistic set of programms/feature on N7

Hi, a new guy here!
I recently became a happy owner of 32Gb wi-fi only N7. I’m familiar with software dev (windows developer for 20 years with some work on unix) and customization/modding/flashing process (mostly for satellite receivers). However this is my first tablet and my first Android device so I could use some help 
I successfully unlocked, rooted and installed custom recovery on my N7. I would like to get to a bare bones state of the N7 and then slowly add new features/programs to it when it becomes necessary for me. So I would like to remove all non essential parts that were preinstalled on my N7.
I was under impression that I could uninstall programs using N7 UI after device gets rooted. However it seems that for majority of the apps I still only have an option to disable.
I shelled into N7 and looked around. It seems that all (majority?) of the apps are in /system/apps folder. Can I simply remove the apps and their files from that folder? Does this folder only contain user apps or does it also have system apps that are essential for N7 to function? Is there a chance to brick it by removing something (everything?) from that folder?
I searched on a forum for a list of apps that are safe to remove. I thought it would exist since it seems to be something many of us would be interested in doing. I didn’t find the list. If there is such a thing and someone could direct me there, it would be great!
Given that I can remove apps by deleting them from that folder safely, I still have a question what each app does and how important it is. Is safe to assume that any app that has a wheel with a drive belt on it as an icon in apps screen on N7 is system app and has to stay?
I have two keyboard app installed – one is Android keyboard and one is ASUS keyboard. Judging by the name 2 of these are essential since Android is the OS and ASUS is the manufacturer. But do I really need two of them?
If there is a resource/thread that discussed something similar, please let know. I look forward to learn from anyone on this forum! 

I don't have the energy right now to address every app one at a time, but I'll nudge you in the right direction. That should help you start tinkering.
The Nexus 7 is very popular in this community because it's intentionally more open, and less bloated, than much of the competition.
That being said, sure there are apps you could uninstall if you decide to. Some of the custom ROM's will have probably already have done this for you, but may create little unexpected quirks here and there.
The first thing you'll want to do is backing everything up thoroughly. I would use Titanium Pro (you'll see it referred to as Tibu a lot), to backup all apps and settings. Then I would use the Google Nexus 7 toolkit (found in the forums here) to do a backup, as well as make a nandroid backup.
Ok, so you're ready to tinker. Well, if you bought Titanium Pro from the app store, you've already got all you really need. First, use titanium to freeze an app you don't feel you need, and don't think is required. Re-boot, go about your daily routine, and see if all is ok. Continue on in this manner. Once you've frozen everything you're interested in, and made sure all is well, you can probably go ahead and uninstall them through Tibu. Freezing them should generally make them not start up anyways, so unless the tiny amount of space they take up is a concern, that's really all you generally need to do *.
* Ok, sometimes you have to fully uninstall things you don't want, but this should get you plenty to tinker with for now.

bladebarrier,
Thanks for your response. I understand the approach you suggested – disabling apps one at a time and then when they all disabled and device is working to my liking for a while I could uninstall them.
However, I’m somewhat frustrated with a sheer number of apps that I have out of the box and I can’t find a good description of what they do. For example:
Mobile Network Configuration
Google Partner Setup
Google Services Framework
Searching online doesn’t yield definitive answers if it’s something I need or will N7 work without them. I have google play store and google play services installed – does store app require services? Reading a bit about it doesn’t make it seem so, but I’m not 100% sure. So I was wondering if there is a list of apps that are required for N7 well being and that cannot be removed no matter what.
For example, Black Viper has an excellent example of what I’m looking for but for windows nt services: (can't post a link)
This page explain what each service is, what it does and if it’s safe to disable it depending on configuration you’re seeking – minimal set, typical, out of box of experimental. I would love to find something like that for N7 system apps 
I installed CWM recovery when I rooted and as far as I can understand I does NAND backups. I plan on moving the backup file from the device to my desktop and keeping it there for safety reason.
The Tibu process that you described, as far as I understand (and I might be wrong here) is basically equivalent of disabling the apps using native N7 setting app, rebooting, using it for a while and then removing .apk and .odex (or simply app_name.*) files from system/apps folder. Tibu just makes it easier. Did I get that right?
And it’s still removing one app/widget at the time. I’d like to clean it out completely first and start from that point. So Tibu will probably not help me there. So my main Q is still out there – can I brick it by removing everything from system/app? Are there only user apps there or essential system apps as well? With CWM back up file on hand will I be able to recover if my experiment goes bad? 
> * Ok, sometimes you have to fully uninstall things you don't want, but this should get you plenty to tinker with for now.
One of the reasons I want to have them removed is to clean up the list of apps I have on N7. Right now I have 5 pages of apps and I have little idea what they do and if I need them – I had Korean keyboard installed for example.
As I mentioned I’m a newb in this area, so maybe my approach is a bit dumb, so please be patient with me

Removing Google framework services is a big no-no. To be honest, the easiest way to accomplish what you want is installing a custom ROM like CyanogenMod, especially since you've done all the prep work for such a thing.
Once you install any official CM build it is as close to app-less as you can get on a modular OS like this.

that's what i suspected! i thought that google framework would be something essential, but there is not much easily available information there to arrive at that conclusion
since i'm new to this, i thought i should stay away from any rom flashing until i get a bit more familiar with a device, terminology and stuff like that. i'm looking at the "[ROM] CyanogenMod 10.1 [OFFICIAL]" thread and i'm not sure about half of the terms - GAPPS, PSA, Nightlies i do know what ROM is, I do know what kernel is, virtual machine, etc. But it's applied to the platform that I have little experience with, so it makes me a little bit uneasy

Tibu requires root access, in order to perform what we're discussing. I'm relatively new to JB, but I can't imagine any stock settings replicating its capabilities.
As far as a whole bunch of apps being in your list, that's sort of the way Android works. Think of it like "superfetch", or whatever that term was in Windows Vista. Basically, two things happen when you boot. Android looks at a list of apps that are designed to start on boot, and also apps that it expects you may want to run in the future. Both of these are designed to make the device run smoother overall, and it will kill apps if extra ram is required and they are not in use. Certain Android apps require themselves to run at all times. Some of these are apps like Tasker (if you're using tasker profiles), some of these are system apps that make the device function, some of these are apps that maintain widgets or background monitoring (weather apps, gmail, calendar).
Now, there are two ways to go about sorting what is bloat, and what is there because Android decided to load it. You can install an app called Autostarts, that will give an insight into apps that start up when certain criteria are met. You can also use it to stop those apps from queuing up at those trigger points. This is another root required app, and while I purchased it long ago, may have a free version as well. It's time consuming to use, and not perfect, which is why Tibu is better for flat out locking down unwanted apps.
Back to my initial thoughts though, you will see apps in your system list that you haven't touched since boot, because Android tries to anticipate your needs. People used to use "task killers" to close the apps, and came to realize that unless one is causing a real problem, it's just going to go back into the cached app list again anyways, thus reducing battery life when it has to load it over and over again. "Task killer" is a dirty word around XDA, unless you're using it to close an app that doesn't just go into the background like a good little app should.
Basically, you're going to start playing whack-a-mole if you want your list to remain as small as possible, at all times, and yet still actually use the device for anything interesting. You can reduce it, via various methods, and if this were a device from say "insert-name" brand, and was loaded with bloat apps, by all means you should clean those out. However, I think you'll find that while google does install things that aren't needed, or even used by everyone, it's mostly not a big issue.
Check out Better Battery Stats, in the XDA forums. It's an app that shows a pretty good picture of what is actually going on when you're not looking, and can provide data on how to improve your performance. It's probably a better way to start delving into what processes are actually being used, and which ones are just basically harmless. You'll also learn a good bit about how Android works from the Dev's explanations of many of the processes.

Make sure whichever ROM you use, if you decide to, supports your HSPA+ model. There is a separate development section in the Nexus 7 forums, for those of us that have the HSPA+ version. We are the minority, as the Nexus 7 was initially released as a wifi only tablet.

i do have SU privileges, so what i was talking about was disabling an app thru N7 setting screen and then when i deem the app ok to remove, going to adb shell and removing the actual file.
i just did this:
mount -o remount rw /system
rm iWnnIME_Kbd_White.apk
rm iWnnIME.apk
and it removed the japanese keyboard. however when i go back to app screen under settings, i still see it but now it has a grey icon with a SD symbols in the corner. so it appears it recognizes that the app is gone, but it's still referenced in the list. i pushed the files back using NRT and it all back to the way it was. so looks like my idea of cleaning the list by removing the apk might not fly.
and now I wonder how Tibu uninstalls the apps.

I understand the notion of apps being in the cache and being removed when more RAM is needed, however the purist in me just doesn't want the junk apps to be there in first place However there is a lot of validity to these of your words:

My wife got Kindle Fire HD recently and she's been using it happily. While I was thinking why would anyone want a closed up system (well, more closed up system then Nexus), she's been using it and I've been frustrated with my N7 so i might just let it go and enjoy the japanese and korean keyboards anyway

i think i found what i was after: http wiki.cyanogenmod.org/wiki/barebones (url modified since i still can't post urls). this wiki page has the list of app with a short description and if it's safe to remove. it also has additional information that explains why i still saw the reference to the app in the list when apk file was deleted:
looks like i need to pay attention to 2 additional files:
/data/system/packages.xml
/data/system/packages.list
i bet I would find a reference to the apps in these and i would need to remove it in order to have the app disappear from the app list. i'll play around a bit more and report back

One thing, could you explain your reasoning behind wanting to delete everything but the essentials? Do you have a particular goal in mind or is it because of your windows background? Because if so, you should know that android operates very differently when compared to windows, and such, the requirements to keep your device working in tip top shape vary greatly.
In my opinion, with your current limited knowledge of each process/app inner workings, what you're trying to do surefire way to break something beyond repair and needing to use a factory image to get back to zero. A custom ROM will be much safer and yield the exact same results that you're looking for. (Eventually, once you understand what each thing does, then this manual approach could satisfy your needs)
Note: GApps are the basic Google apps to flash on top of the barebones system. Gmail, Play store, and the framework.
Nightlies are experimental builds compiled nightly by a bot with the latest CyanogenMod code available.

My goal was to simplify my approach to N7 by removing anything that I don’t need now and slowly adding all necessary components as I get familiar with it. But it seems at this point that this approach is a bit more complicated as thought it would be.
So I think I would leave it alone for now and revisit this later 

From what you've done manually, you're clearly far ahead of a new user when it comes to understanding linux/unix.
If you want to lock down parts of what google implements, purely to keep it minimalistic, I would agree with the above poster. Go for one of the popular ROM options that are available, like CM, and work your way backwards. The Nexus 7 only has as much bloat as you allow it to have via the settings. This is another reason why Better Battery Stats is an excellent way to make sure your device isn't draining battery, yet isn't locked down. The other day I noticed an app that kept fetching my position, even though the case was closed (magnetic sleep mode). It turned out I forgot to disable the tracking in google maps (why it was defaulted to ON, I have no idea). BBS showed me what was running during the sleep phase, and I fixed it when I woke up the next morning after wondering why my battery dropped.
The Kindle Fire is a great option, because it doesn't require any of this fussing about. My woman loves hers. LOVES IT. Personally, I like to tinker a bit, and I'm too invested in Android apps to not have access to the play store. The Nexus 7, is for people like what you find here. We like to tinker, and make everything custom. At the same time, you could spend all day trying to figure out why EntriesRefresh_wakelock is your highest partial wakelock count, at 60seconds per 7 hours, or you can find that you just went 7 hours and only used 6% of the battery, even though you've been connected to wifi, texting, emailing, and checking the weather and news, the whole time. Not bad, honestly.
The biggest investment you can do for your Nexus, is probably getting a case that magnetically puts it to rest when you close it. After that, learn about the settings that drain battery in the background. Then, get Tasker and play around that (it's like programming, without the need to learn the code). After that, go to a custom ROM, or dig out Tibu, and basically start customizing which apps you will use. If that doesn't pass the time long enough, you can literally make your own ROM and put together exactly what you want. Whether the performance will be that much better or not, and whether you'll spend most of your day trying to look for coding errors, is up to you. I don't have the patience to code, but you're a coder, so what is broccoli to me, may be bacon to you.

[Q] Unwanted Ad notifications

Hi all,
I keep getting ad notifications popping up. Sometimes they're links that take me to a web page then to the G Play store for "Candy crush saga", other times they're survey questions like "Do you want an iphone 5?". I've run a few apps that look for adware, and also long-pressed on one or two when I could, and both point me to the Network app, which looks to me like the Android-native network service (it has an icon that looks like 4 or 5 bars of increasing height, kinda like you'd see for a wifi service). Is this just something I get for buying a piece of Google hardware? Or, is there some way to stop this annoying behavior w/o having to put a whole new ROM on there?
Thanks.

I use to get these mid-video on the Funimation app — it was incredibly annoying. I finally got rid of it by rooting my devices (Nexus 7 and 4) and installing AdAway (system level adblocker) from the f-droid appstore. So, no special ROM, but rooting was needed.

You can also disable notifications from certain apps. I've never gotten ads from the native ROM, its something you installed. I believe they'd apepar to come from the Network app anyway, even if they didn't. Find out what apps you installed are ad related.

I would disable the Network app's notification permissions. If it is a system app, this really shouldn't impact its performance (unless you prize the "Open Wi-Fi networks" notification. Even then though, I'm a little concerned that you have a network app. Can you give us the full name of the app and tell us what buttons are available from App Info (e.g. Force stop, Uninstall, Uninstall updates, Disable, etc.)? I just checked through four or five of my devices, and I don't have a "Network" app on any of them (including on my Nexus 10).
I'm wondering if it's not just some incredibly shady app name.

[Q] Virus or Android now Untamed?

Hello Good People of XDA
I have been a i9506 owner for quite long, had a 9100 before,
I am used to root and mess with apps to customize things to my wim,
at the best of my knowledge (I lack android programming skills, but I can do things with terminal and filesystems).
All that before to say I am not totally a noob, but my lack of technical knowledge might bite me there.
System wise, I am under 4.2.2, rooted, unknow sources are not allowed, system check for apps is allowed,
I have an antivirus (more than one, but only one works each day, just to be sure I don't miss things)...
My problem is that I recently found out that some apps, actually system apps, blocked
with Titanium backup, or with gemini app manager, or app quarantine,
were actually running anyway.
They are marked as blocked in my app manager, but can still be force closed,
and they appear in battery displays (most of these under the android system block, in the list of services/apps used),
and in process running when using Ccleaner apps.
Also, my battery display show GPS is activated, while when I go into options, all boxes are off or unticked.
I thus wonder what's happening?
How is it possible to have these schrödinger apps tamed and blocked like I want them.
I want these to shut down and only work when I DO ALLOW these, for them not to suck my battery or do unauthorized chores like tracking me when I don't want.
How is it possible that they even behave like that? In i9100, I never observed that in Android 4.0.
I wonder if Google didn't change the workings for making us unable to disactivate what we don't want to work, which was pissing them off.
They already change the permissions displays in the market so permissions as intrusive as "contacts/sms message/USB stockage" are considered "not relevant/important",
while they are depending on the announced display of the app.
But I don't want to go on the "conspiracy route" (I am not like that, I am a pragmatist and I just observe facts, like these apps, with sensitive access, not being able to be deactivated), so let's focus on the technical part:
such apps were Maps, Samsung sync adapters, NFC service , Google Agenda/Contact synchronisation, sysscope, context provider, etc.
That's a lots of things that are supposed to communicate to cloud or other devices, with feels lot like a gaping flaw in the armor...
I want a phone and a tool, not something that track me or put me at risk of being stolen by somebody with technical knowledge.
Am I alone?
Thanks for any insights.

Blocked apps still working
I don't know if my title was too unclear, so I would like to change the title but am unable to do so?
Is it please possible for a moderator to do it (with the title of this post)?
Thanks by advance.
I feel like it is a true problem not being able to block some apps,
or even more, to believe they are blocked while they perfectly perform in the background,
and display activity only in secondary reports, not under their respective "buttons"/information tabs.
I wonder abourt the technical reason to such behavior.

Then delete those apps or block some of the permissions with an app (eg Privacyguard).
It's my opinion that an antivirus app (at the moment) is a waste of resources. Just think before you install something. Also if you are worried about security, you should always run the latest version of Android. 4.2.2 is an old version.

Thanks for your answer.
Well I don't want to delete system app when they might be useful at time.
I just want them to behave correctly, that is, not work when they are blocked.
That is not a solution to say "uninstall this", while the true problem is Android general behavior here.
I didn't installed system apps, they came with the thing, and all of them are not bloatware.
"NFC service" is something I want to keep for when I am ready to use it,
but I don't want to let it free and unleashed because of the opening it leaves on my phone.
Same goes for bluetooth, synced backups and so on.
I don't want backups on the cloud, so I deactivated the options, and blocked the apps.
Why are they running? It is not normal!
And my old version is maybe not secure, but actually trying 4.3 hasn't changed anything,
and I only suspect this to be some "new feature".
The antivirus is a waste for scans, I agree, still it has useful firewall features that justifies in itself its uses.

The Next Best Thing to Root... or, how to de-screw your stock U.S. Galaxy S7 T-mobile

Presenting.. the Next Best Thing to Root for the U.S. Samsung Galaxy S7 T-mobile edition (model SM-G930T that is)
As of 6/7/16, no root is publicly available. I purchased my S7 on 5/26/16 and decided to keep it despite the lack of root. This is my story.
INTRO
So the ol' Galaxy Note II up and died on me a couple weekends back, and I blew 40 bucks on a new battery before I realized it was gone gone gone. Queue new phone shopping, the hip glasses-toting dudes at T-mobile swayed me to an S7. I didn't want something as big as my last phone and forget using a bumper case with that curved-screen edge (an acquaintance of mine quotes: "The only thing that ****ing screen is good for is when I'm high as hell and want to read the clock without lifting my head". He dropped his and shattered it.), so I went with the plain ol' S7. Well, now I know why the salesguy got real quiet when the first thing I told him I would do was 'root the phone'. Being a programmer, I was pretty bummed and unhappy about owning a device that I am purposely locked out of Administrating.. but the return fee was $50, and I really liked what the S7 brought to the table.
Goes without saying, I was ready to pay for the rootable HTC-10 (my local store didn't even carry it, the salesman said they were 'test-marketing it' at a couple other stores across town) or the LG monstrosity (I haven't liked this company since the spying TV debacle, tho once upon a time they made good and cheap TVs), but I hated how much bigger the devices were and that svelte S7 really impressed me otherwise. Samsung really does make the 'iPhone of Androids'.
So, I decided to stick with the S7, and un-screw it pretty much as best as I could. And, because all I read was mostly a lot of 'is the root out yets', I thought it would be cool to share.
ABOUT THE S7
Not too terribly much has changed in the android linux filesystem since the last time I seriously delved into it. Got a vague idea where most of what is what, but I also recognize that the Path to Rooting is two: Utilizing a bootloader to actually flash the chip, or Piggybacking on some existing Administrative-privileged software in the otherwise 'closed' environment. Samsung shipped the U.S. T-mobile S7's (mine is SM-G930T) with a locked bootloader to make it nigh-impossible to root via flashing. Get to it, ya chip-hackers.
However, it is a universal law of the internet that someone out there will find an operable software workaround, and this is usually some 13-year-old kid from Finland, or at least it was in the case where I found drivers for a Voodoo 3 card during the advent of Windows XP. God bless the internet will provide, and in this case that gentle soul is none other than a man by the appropriate name of OSPolice.
PACKAGE DISABLER PRO - THE 99 CENT APP
play.google.com/store/apps/details?id=com.ospolice.packagedisablerpro&hl=en
This little gem of an app I purchased for $0.99 off the play store. This is the key to enjoying the disabling features of Root access and the key to un-screwing the T-mobile Galaxy S7. What this app does is essentially co-opt the Administrative access that Samsung Knox (the 'security' software) uses and allows you to disable any and all packages on the phone. When you first activate it you will have to accept an agreement tied to Samsung Knox (don't worry, this in no way causes anything to 'phone home' as far as I can tell).
I would recommend the very first thing you do is go to the settings and add a password to the app, that way nobody else can get in, because this can seriously **** with your phone's software, if you disable the wrong package the phone will not boot up properly and you will need to reinstall. There is an option to Disable All Bloatware based on automatic picks from the application but this can screw up some phones and you will miss a lot of crap, so DO NOT AUTO-DISABLE.
There is also another important reason you should manually disable these. Clicking on a package from the main app brings up a screen where you have several options (the auto-google feature is quite helpful to researching various processes). There is also an important little button that says 'Clear Data', erasing the temporary package data. Due to info I found on another forum, which I am too lazy to dig up here and now, there is an important process to disabling with Package Disabler Pro:
THE DISABLING PROCESS
1. If the package is not enabled, enable it.
2. While the package IS ENABLED, click Clear Data.
3. DISABLE the package with the Disable button.
4. Click CLEAR DATA a second time.
5. On to the next one...
It appears there may be some data that is not erased when the package is disabled. In any case, this fixed all of the problems I had disabling earlier without using the Clear Data button. This is important to stop certain packages from utilizing an outside process to re-enable themselves.
Below I am listing all of the processes that I disabled. Your list might be different; before I did this I updated the phone's system software from T-mobile's servers (as of 5/25), and I don't plan to auto-update again until I root or have to reload everything.
Also, please keep in mind I turned off a few features with this method, you will have to ADJUST YOUR PACKAGES ACCORDINGLY or know what to re-enable from the below list. I turned off all wi-fi calling (don't like 'weird' internet connections), all NFC and payment such as the Samsung pay chip (nothing I want/need enabled right now). I kept Bluetooth connectivity on since I pair the phone with my car for and it's more or less an 'established' form of protocol, neverless if I didn't use it I would deactivate it as well. Security Over All is my philosophy.
THE SINGLE PROBLEM I HAVE HAD is being unable to 'browse' for a background when choosing a new one for the lock screen. I kept the lock screen with a stock dark blue and had already set my live wallpaper (play.google.com/store/apps/details?id=com.dkeesto.holographlw&hl=en if you are curious, Digital Hive by the unsurpassed Cypher Cove). So set your backgrounds before disabling all these, or try and figure out which disabled package screws this up, though I tried re-enabling anything with 'wallpaper' in it to no avail.
I also disabled a lot of the Google services, I check my gmail online, phone apps seem so hideously insecure to my mind, and I don't want to use any drive or cloud backup services AT ALL. Go with an all-encrypted service or backup your data yourself, and I don't trust any non-rooted backup apps. If you use the Gmail app or etc, simply don't disable it.

A FEW OTHER FEATURES I DON'T USE
Fingerprints.. never tested with this. I fail to see the usefulness of a fingerprint compared to a password in your head, and it's a whole lot easier to duplicate the former and scan someone's phone (call it the 'law gets in' password). So some of these might have disabled fingerprint functionality.
Voice-assistance.. again, the possibility of my phone recording me without me knowing is kind of scary. There's a lot of Samsung S-voice crap built in, I had this sort of thing on my last phone and never had the need for it.
Always-On Screen - It displays the time, had it on for a couple days and it worked just fine, but ultimately a battery eater, and the config options are real limited. I ended up turning this off.
The Samsung TouchWiz Launcher - As soon as I got all my packages disabled, I ditched this one. You can use anything you like, but personally I found a new home with NovaLauncher.
The Camera I tried to keep as whole as possible, I set it as the 'double-home-button-click-to-open', which was default behavior, and I really like it this way - double-click and you have a camera, and it works regardless of locked screen. They've really improved the camera software, I can double-click and start recording and that's just the way I like to use a phone. Now if there were only a way to compress, encrypt, and auto-transmit those movies immediately after recording...
DEVELOPER OPTIONS
Settings -> About device -> Click on 'Build Version' a bunch of times. If you're reading these forums you should probably know how to activate this.
Some cool settings, the only one I toggle is USB debugging.. for ease of file transfer on a PC thru USB cable, something which ALL modern phones suck ass at. It almost makes me want to program a simple universal file transfer software suite.
WHAT I WISH I STILL HAD
Encrypted Backup Solutions/State Backups: TitaniumBackup & Nandroid are the ****. Man do I miss having root access.
Customized Pull-down Notification Screen: I hate that first row of settings buttons. I will probably have to pony up the 5 bucks to NovaLauncher to see if they can make those go away.
One-touch Reboot app - Not getting this one until root Administrative access. I'll have to live without until then.
Otherwise, I have been pretty conveniently able to live without Root on this phone, and I hope this guide can make you happy, too!
SOME APP SUGGESTIONS - USEFUL
I've peppered the above with some apps I really like, here are some more:
Firefox - My favorite browser. I keep a copy of chrome for emergencies. 'Noscript' and 'Phony' are must-have extensions. Still looking for a good page-to-pdf extractor.
Orbot/Orfox - Best TOR/browser combo.
Rocket Player - FANTASTIC music app that I ponied up the money to unlock (mostly to play FLACs). Near-perfect, and a relief because Winamp **** the bed when it came to Android.
DuckDuckGo - I use this to replace the Google search bar widget. Doesn't work the same (click to open) but works quickly.
ZDBox - I use this exclusively for the 5x2 'control' widget on my home page. One-touch turnon/offs (or some options send you to the settings screen) for the following: WiFi, Bluetooth, GPS, Mobile Network, Airplane Mode, TaskKiller, disable Screen Rotate, Brightness, Applock (you specify) and Flashlight (my default light, big screwy button but I'm used to it now).
ZDCal - From the makers of ZDBox, a free calendar that displays as a strip in the notification bar and also places a date at the top of the screen. Be careful, the first time I set it up I blindly clicked a couple pages and set up a period calendar that promptly notified me when I was beginning ovulation (I am a man).
SOME APP SUGGESTIONS - GAMES
Stellar Solitaire - The best Solitaire app ever. Tons of games, demos, beautiful for a phone screen.
Cliffy Run - A rager game my awesome friend made that is totally and amazingly simple and has some great graphics.
Neko Atsume - A stupid japanese cat simulator that I can't stop checking.
Source - A free 'pipes' puzzle game. I'm at 1 hr 2 mins on insane level. Great for killing time in the DMV.
SOME APP SUGGESTIONS - PROGRAMMER/NERD
OS Monitor - Process/Connection task-manager
JuiceSSH - My terminal app of choice.
Blowtorch Beta - My MUD app of choice. Told ya I nerd.
AndFTP - My FTP/SSHFTP app of choice.
AndroZip - My compression app, and, surprisingly, file manager of choice.
Fing - 1st of the 2 best wireless discovery apps ever.
Wifi Analyzer - 2nd of the 2 best wireless discovery apps ever.
Usemon - Resource Analyzer. Has a cool option for the notification screen, and measures both frequency and % use graphs when many progs do one or the other.
Cargo Decoder - If you want to read what exactly is in the tanker truck you are driving behind and how badly a spill will **** up your day.
Maverick - For all your GPS/compass/accelerometer needs.
FINALE
Please feel free to add anything to the above! I am pleased that I got my phone to do most of the things I wanted without a root. That being said, as soon as it is possible I will be jumping on that train. If you have any suggestions, please contribute! And thanks for reading!

Solid post man. I will be looking to clear data on my disabled apps. That is great advice. Thank you for this!
I can say i agree, mostly. I too miss root, but can manage without it. I really wish I still had full functionality of tasker. I had some kickass gps profiles and such that I can't use anymore. Do you know a workaround for that?

great post. im bummed as well regarding the locked bootloader that TMO has implemented. It's still a new enough phone that I'm trying to get the 'samsung experience' so personally disabled lookout and the TMO crapware. I will be saving this post for when I'm ready to go barebones (like I always eventually do) does anyone know of a good rootless ad block? Every time I launch a game and stare at a 30 second video for a different game it makes me miss adblocker terribly

I used this list as a base for safe to remove applications. Ridiculous that Samsung thinks it's this necessary to have this many applications installed.
I use the Theme Engine and a few Samsung apps (their browser with Crystal Adblock, works great and I also use Screen Mirroring/Quick Connect.) So I skipped disabling those, but got everything else. Thanks for the list. Looks like you spent a lot of time compiling it all together.

Seems to have definitely made the phone a lot snappier so thanks for this! However I can't seem to figure out which is affecting my wifi calling. It'll turn on on reboot but if it drops it won't come back on. Any ideas? Also I didn't turn off the lasy three ok his list.

Could you please share the XML file of PACKAGE DISABLER PRO? ....
PS Thank you for the great Post!

Did you ever find out why WIFI calling isn't working properly? Mine won't even start on a reboot!

Looks like Debloater will do the same thing as well.
Thanks for the list of apps that i can safely disable

Very nice write up..

1st: Excellent post, lots and LOTS of detail!
2nd: OMG, I hope I don't mess anything up!
