There's not a lot of information out there for the Galaxy Core Prime on how we might debloat and save more space, so I decided to make a short tutorial that might help people with some easy steps in cleaning up their device. This guide is meant to be pretty basic and to just help point people in the right direction so that it speaks to a broader scope of Galaxy Core Prime Models, but is based specifically on the SM-G360T1. The SM-G360T is essentially the exact same phone though, so all of these steps should apply directly to that device too. Other Galaxy Core Prime models will be able to use this as well, but just be sure to read the special "NOTE" part of each step. Also, I'm sure it goes without saying, but inevitably I'll get the question, so obviously, root is required for this!
Anyhow, here we go:
1) Do a full backup in recovery before deleting system stuff. This is always a good idea just in case you delete something you're not supposed to and android stops working, then you can just go into recovery(TWRP, CWM, etc.) and restore your backup and your back to square one. It's good to do a new backup too a few days after when you're sure your deleted apps aren't causing any problems so you can restore to that slimmer version later if need be. Also, you should probably save your backup files to the external sd as you will likely have more free space there.
2) Install a debloated rom in recovery. SlimPickins is a great one for the SM-G360T1. It's basically the stock firmware for the MetroPCS Core Prime, but thanks to @Koognod we can now run Android without all the extra junk using his rom. It comes already debloated, deodexed and deknoxed, so you can just install it and not have to deal with finding all the junk to delete for yourself. It's already gone! It's also great for speeding up your bogged down phone or creating more space for your apps and media. Here is the link.
http://forum.xda-developers.com/gal...rom-slimpickins-stock-rooted-bloated-t3250883
NOTE: YOU CAN NOT INSTALL THIS ROM IF YOU DO NOT HAVE THE SM-G360T1. It should work fine on the SM-G360T too, but for anyone else just try googling or searching XDA for your "model #" and "debloat rom".
3) I recommend deleting the "PreloadInstaller" folder from "/system/app/" with a Play Store root browser. You should do this before deleting any system apps in my opinion, as this folder contains an apk that is programmed to put back a lot of the system stuff you delete(either immediately or after reboot). If you don't feel comfortable deleting this folder just yet though, then you can just move it to your external sd card for now with your browser to save space in case you ever want to move it back or just skip this step. Your choice!
NOTE: If you don't have the SM-G360T1 or SM-G360T, then your "PreloadInstaller" folder may be called something slightly different or you may not even have it at all. Just look for something similar in there. Be careful not to delete the package installer though as that's the program that allows you to install apps yourself.
4) You need an app that uninstalls system apps. I use "System App Remover(ROOT)" from the Play Store personally because all your deleted system apps actually go into a recycle bin first where they can be restored later if needed. It also tells you if the app in question is a "Key Module"(ie. proceed with serious caution).
5) Google search the internet for system stuff that's ok to delete for your device. It helps to search your model usually, but I don't think there's much info out there for the Galaxy Core Prime unfortunately, so just searching something like "Debloat Samsung Safe" can be a great resource as many Samsung phones have the same system junk.
6) Delete all the obvious stuff you don't want. This would be things like any of the MetroPCS stuff(or whatever carrier you have) or even the Galaxy app store if you don't want it. A lot of Google apps can be deleted too, though you want to be a little more careful with those as Android is pretty much based on the Google Services Framework and many Google apps are tied into the system. Generally, apps like Chrome, Docs, Drive, Hangouts, Maps(if you prefer another map application like Waze or whatever), etc. are good to go if you want. I wouldn't delete any of the core Google apps though that may handle major processes on your phone, like Calendar, possibly even Gmail or any of the ones that you don't know what they do. Deleting the stock camera, gallery, video or music player may sometimes give you problems down the line too, so I would probably keep those. You can also back all your apps up before deleting with Titanium Backup from the Play Store too in case you delete something that you need to put back later.
*NOTE: Some apps, like the Google ones for instance, may cause popup errors after you delete them. This is normal. Your phone's just looking for all those files that were just secretly running a few moments ago. All you have to do is reboot to get rid of those messages. If they still persist, then just reinstall the app.
7) Download an app to clean up that leftover mess. When you delete an app, especially with system stuff, it often leaves a bunch of folders and junk behind. Go to the Play Store and download an app that allows you to clean all that up. There's lots of good ones. I like to use one called "SD Maid" myself. It's good at cleaning up those leftover files and has a feature called "CorpseFinder" in fact that does just that. It also cleans up a lot of other things on your phone.
Anyhow, if you're a heavy power user like myself or you store a lot of music or other media on your phone in addition to 20 million apps or so and you need more space, then I hope this helps you out. Take care guys. Thanks!
Out of curiosity, how does this affect the "phone unlock" feature? In case I want to change providers?

It won't affect it at all as long as you don't delete the "Device Unlock" app. More info on unlocking your device here:
http://forum.xda-developers.com/showthread.php?p=63729887
Also, you can just install SlimPickins if you want an already debloated rom.

Hi folks,
As you can tell from the title I'm a smartphone noob and didn't realise you couldn't do this (see the amount of people I've spoke to who didn't even notice you can't delete apps that come with the phone! What's with that?).
But as you can see I emphasised the 'why', 'cause I've searched everywhere but can't find a reason as to why. I'd assume it was just so you can't delete bloatware, but even the Nexus that runs on stock Android has the same issue.
Does anyone know why (or guess why) you can't delete preinstalled apps?
Thanks!
If your device is rooted, all you have to do is download Root Explorer from the market and delete the APK files from the system.
They're located in: /system/app/
You have to press "Mount R/W" on the top right of the application before you can read and write. Make sure hit "Mount R/O" in the same spot after you're done editing though. Also, make sure that what you're deleting isn't something you need and you should probably back-up the .APK files to be safe. If you mess up and don't back up, you can still just re-flash or re-download GAPPS without a problem. Have fun .
Thanks
I was thinking about rooting my phone actually, I'll check that out (I'm sooooo going to back up everything lol).
But! The question was WHY you can't delete the preinstalled apps. Does anyone know the reasoning behind it?
You're welcome mate .
Just for safety I suppose. And you should definitely root your phone, it'll open a whole new world for you!

That and basically without rooting your phone it's basically like a comps guest profile. A lot less can mess up if you can't play around with certain files/settings.
Makes sense.
Thanks folks
I am also unhappy that i cannot uninstall apps that came with the phone and i have yet to find a good reason as to why not. most of the apps i want to delete are free on the market, already compatible with my phone and can be deleted or uninstalled without causing any major issues.
tmpchr says "manufacturer /operator agreements..."
ok ill buy that, sounds like a good business opportunity, (i would do it) good advertising, shared/reduced costs...etc. but the end user should still have the option to remove.
I totally agree with you guys, at the very beginning I had so big apps installed on my device (motorola xt720), for instance MotoNav was about 1.5 GB and spoiled my battery life. Luckily I discovered how to root the device and now, using "root uninstaller" that you find in the market, all of them are just a memory
You could also use Titanium Backup to remove programs.
I have recently purchased a Samsung Galaxy S2. I have the phone set up the way i like it but i wish to try different OS versions which will require rooting and wiping my phone so a few questions regarding backups:
1) Currently i have my gmail contacts and facebook contacts "linked" together. I believe this is only stored locally on my phone. Is there a way i can save all this contact info so when i log back in to my profile in the future it will all be seamlessly placed as it was.
2) Currently i have a whole batch of homescreens with icons and widgets and my applications screen with every app in a "folder" can i back these up exactly as they are?
3) Within various different applications there are different options or save games and various things like that, are these easily accessible and able to be backed up
4) Finally can i just do an "image" of my phone and if i wipe it and mess about then simply restore that image back to exactly how it was?
Cheers for any help
boxrick,
Can't answer specifically for the Galaxy S2 as I don't have it, and because Android is "pimped" in various ways by different device makers some of the homescreens/layouts are custom implemented, and best backed up by the methods appropriate for--or offered by--that device.
Having said that, if you are using Google market, a lot of stuff (like the apps obviously) is automatically saved with them. Or the apps themselves can be backed up with any good file manager, like Astro, to an SD card or via USB.
I can't answer you about the Gmail & Facebook contacts being "linked together", but from experience most items are stored in the Google Contacts data-fields and stored remotely in your Google account (and therefore restored from there straightaway)
I have multiple Android devices, and to tell you the truth I pretty much just copy everything "en-masse" to a hard drive. If you're rooted, it's fairly easy to pull down almost everything this way. You're just dealing with files and folders, just like on your regular computer (which is why I'm pretty much done with anything "black-box" like formerly iphone/ipad, btw )
If you're looking for a "set-it-and-forget-it" type app, I don't currently use any, but on my travels I've seen a few "names" tossed around with good reviews. You can research
MyBackup Pro
Sprite Backup
Those two are pretty well known full-blown-backup type apps. They're paid apps, but cheap.
I've heard of The Missing Sync which takes a different approach by syncing all your data to a Windows or Mac desktop for backup and also for re-distribution to other devices. Sort of like a "data-centralizer" type approach, which might be up your alley. I think the app runs about $40 though.
Finally, I do use the free LifeSaver 2 app for important SMS messages and call logs-- picked it up over at F-droid.org. It's for pretty specific data types, but it's this stuff that usually is the hardest to save (since I don't actually know where it is when I backup the entire root directory + subs & files).
Hope the above gives you some ideas. My general advice would be to research, read the boards, with special attention to the threads dedicated to the Galaxy S2, because the other users have gone before you
And btw, if you find something really cool (including if one of the apps above turn out to help you), make sure you come back and post your findings. I'm always on the lookout for a "gem" app that makes my life easier.
Good luck!
Apps: Titanium.
Data: MyBackup.
MyBackup does a much better job at saving your contacts than Google does. MyBackup restores them exactly as they were, Google often loses custom fields and messes up your contact names. Just look at the mess when you sync a contact called "Al's Pizza (open 'till midnight)" back from Google. It also gets the timestamps on SMSs right, which most competitors don't.
You could forget about Tit and backup your apps with MyB too, but then you miss out on all the different batch jobs that come with Tit.
There's one thing that all backup apps choke on: widgets. I always have to set 'em up again after a wipe/restore job.
Can't titanium backup both apps & data?
Titanium can backup user data, sort of.
Restoring user data with Tit is not as straightforward as with MyB. They should add a user data screen so you don't have to hunt for your data in a long list of apps.
One final question, if I was to change from Android Phone A to Android Phone B. Will these "apps" and backups be able to restored to a totally different phone?

rogier, what widget app do you use? I use Elixir, and in it there's an option to export widget data. Search for the "edit widgets" button, click it and you'll be taken to a pane where all the widgets are replaceable. Below it, you'll see a "More" button--that's where the import/export widgets button is. After you export widgets settings (you have to type in a name for it), Elixir then saves that exact config. After flashing a ROM and restoring via Ti, you can then choose to add back your widgets via the "Import" button. Remember though: if you want to bring back a 5x5 widget, you have to choose "5x5" widget after long pressing on a blank space, otherwise the widget won't restore properly. With this, you can have as many widgets you want and not worry about the tedious process of reconstructing them after a restore.
do you have to use the paid for version of titanium?

Yes, you can with Google . Go to Settings --> Privacy --> Back up my data.
When you buy your new phone, select restore my data. At first you won't see any difference, but after a few hours your apps will be restored

Right now I've got Widgetsoid, DroidStats, Smooth Calendar, PlayerPro, DroidWall, Make Your Own Clock, and seNotes on my home screens.
Some widget apps have a backup option, some only come in one flavor (like DroidWall) so they don't really need a backup option. But others (like most notes widgets) don't have any backup option at all.
This is really annoying for the sticky notes widgets, because it's often impossible to remember what info you'd have to put back in them (which is why you wrote it in a note to begin with).
So I'd really like a one click option to back up and restore all my widgets.

Nope, you don't. The free version backs up everything too. It just takes more clicks to restore your stuff.
The free version of MyBackup only restores to the same phone that it backed up, so if you want to use MyBackup to transfer your data to a new phone you'll need the paid version.
I have purchased MybackupPro. The problem is I am fairly confident it will not back up my linked contacts. Therefore I need to root my phone and use TI backup...
Id like to post here http://forum.xda-developers.com/showthread.php?t=1125414&page=12 and find out about after unrooting, flashing back to the default kernel ( for warranty purposes ). Need 10 posts
Now it seems I am getting restrictions on the amount of times I am posting. This also doesn't help me much!
There's a bunch of crap that comes with this phone, including Bejeweled 2, dT Sync, KidZone, My Account, My Device, Notes, Slacker Radio, T-Mobile Mail, T-Mobile TV, TeleNav GPS, qik Video Chat, and Zinio Reader.
Which of these can I uninstall (using Titanium Backup) and not mess things up? I ask because Media Room has T-Mobile TV and Slacker Radio tiles and I don't want to lose access to my videos and FM radio if Media Room refuses to start after uninstalling say Slacker Radio.
There are already lots of threads about that in this forum... Just search or browse and you'll find lots of useful info. You can freeze Media Room, T-Mobile TV, and Slacker Radio without any problems at all, but if you freeze one or the others and they're trying to access the other program that may cause problems. Just make a NANdroid backup and experiment! That's what we're all doing!

This thread sums up our pool of knowledge, spread over a couple of threads and condensed into one.
We were bouncing back and forth between freezing and uninstalling, in various configurations right after we got root, and I re-wrote everything into posts 19 through 25.
You can pick and choose what you want to get rid of - the only apps that have a dependency on something else are:
-The two "my account" apps, which is explained in the thread and:
-Widgets after removing the Sense launcher.
Removing the Sense launcher (rosie.apk) means you can't use a majority of the pre-installed widgets that come on the phone. It's safe to remove any and all widgets without affecting the apps they link to, whether you remove the Sense launcher or not.
In that thread I linked, we do not cover removing any of the Sense frameworks or deep system files, just surface .apks - so it's all pretty safe there. The stock camera app will still function, as well as anything else that depends on Sense frameworks to run correctly.
You can pick and choose what you want to get rid of in the list - and it's very specifically listed where the .apk and /data files are located so you can make sure everything got removed ok.
I would recommend using Absolute System Root Tools to uninstall the apps, and make sure to clear the data first.
Go back afterwards and use Root Explorer to delete the empty data folders left behind, and the .odex files that Absolute system (or any other uninstaller) won't get rid of.
Again, all the paths and full names of the .apk and .odex files, as well as the /data folders are listed explicitly in the thread, so you should have no trouble finding everything for each specific app you want to get rid of.
It was a big effort from quite a few people here to track it all down, and we are still adding more stuff to the list. If you find something you can get rid of that we haven't covered, add it to the thread so others don't have to re-invent the wheel.
Happy hunting!
Edit -*(you can use Absolute System to remove those folders and files left behind with the root system file browser I believe, but I prefer root explorer and if you're gonna do this kind of stuff you should pick it up anyway - it's worth the money)
I have no experience with titanium backup, but if you can do all the functions of that with it, then more power to you, post up here if you can use that to delete the empty folders and .odex files that it probably won't get.
There is some way to remove the native apps from my rooted razr maxx hd?

Yes, however it is much better to freeze the app. You can use Titanium Backup to do that https://play.google.com/store/apps/details?id=com.keramidas.TitaniumBackup&hl=en
When you freeze it, under the default setting of Titanium Backup, it will still get updates and remain frozen (won't be used by the system or be in the app drawer or on the home screens). This is much safer than removing it because if the phone misbehaves you can always unfreeze the app as well. There's no real reason to remove the app by deleting it.
If you do want to delete it, then native apps live in the /system/app/ folder, which is mounted as a read only filesystem. Since you are rooted, you can remount it so that you can read and write to the folder and delete the app, however that said, its much better to simply rename the app. I haven't renamed apps in the system folder on this phone (just got it) but have on the Samsung SGS II, which is a much safer phone to play around with like this from the look of it so far, though.
Every app on a stock install has two files, one with a .apk file extention and one with and .odex file extention. From experience with the other Android phone, you can just rename something to, for example, videoplayer.apk.backup and videoplayer.odex.backup. It can be renamed back later if you need to. You want a file browser that will remount the filesystem so that its rewritable. Root Explorer is what I've used but there's plenty of others that are gaining in popularity. It can be done at the command line as well.
All of the above said, though, you really, really, really, want to make sure that you aren't freezing or deleting or renaming an app like this that will interfere with your ability to undo it. If you do something that gets the phone stuck with lots of things crashing and making the phone unresponsive, or worse unbootable, then that's a very bad situation. It was always really easy to deal with from the recovery screen on my SGS II but I haven't yet tried things out on my RAZR HD in this fashion and things are differant when it comes to it. I haven't tried much out yet.
Also, and I really don't want to come off as being rude, and I hate it when people do on this forum, but because you had to ask if it was possible on a rooted phone at all sort of indicates that you might want to get as much advice about what you want to freeze or delete before doing it. Its prudent on any phone and less is more until you've gathered more information; and from the amount of support on this phone's section (low number of people having the phone and tinkering at this point) of the forum my guess is that this it will take some time and patients to get all the answers and information that you want before going balls deep.
Good luck, and remember that less is more, and that support will grow over time.
If you delete you will have a difficult time taking the next OTA. Freeze them. There is almost no space to be had by removing them.
Customizing my Android phone, I've learned some things along the way that I thought other newbies like myself would be interested to know. This information can be found all over the web, but I thought speaking about these key points would be helpful...
1. If you're interested in rooting your phone, I've found the Towelroot method to be easiest. You can download the apk file for free and it makes the rooting process easy.
2. I have a method of disabling apps to improve performance that has never resulted in me crashing my phone. If you are not rooted, this probably won't be helpful. First off, get Greenify Pro and the Xposed framework, along with the ROM Toolbox. For apps that you know can be frozen safely, use ROM toolbox to freeze them, along with killing startup receivers of apps that you can safely disable from stsrtup, but can't freeze because you want to use them. Then use Greenify to hibernate apps you choose not to disable, but don't want running. I've found this method most efficient.
3. Many root their phones to remove apps that are pre-installed from your service provider, like my AT&T apps for example. I've come to realize that removing apps will not give you back usable storage space, so unless you are sure it's garbage, freezing apps is safest. Also, if you remove an app, it would be wise to backup the apk file first, just in case you need it later.
4. Since I'm a newbie, I have stayed away from custom ROMS and the sort. I've come to realize that this process is for skilled users only and many bad things can occur if this process goes awry. Always make full backups before attempting this at minimum.
5. Certain launchers, such as TouchWiz cannot be removed from Android easily, so I'd suggest you add your launcher of choice and leave the factory installed Launcher alone....
I hope this was helpful to all you newbies, good luck!!!!
