I have the 0.7 rom load with both patchs and the blue theme, I want to try out apps 2 SD i just didnt know the best route in doing so, for it to work correctly with your rom. If i use the format function in the recovery menue would it automatically save my apps on the SD and work properly or would i have to reinstall them?

(I personally don't like apps2sd but if you really have that many apps...)
Yea. Backup your sd card (it will get wiped). Boot in to recovery and create swap+ext2+fat32 and then convert ext2 to ext3 (all are options in the recovery menu). It will move everything for you.
Why don't you like apps 2 sd? I just figure if you have that you won't have worry about internal memory if you wanted to have a lot o

**My note about Apps2SD: I added support for it in this release of the rom because people who were using it in other roms that tried to install this rom were receiving errors. Here's my point of view on it.
I played with it for over 8 hours today between implementing it and then testing it to make sure this fix would work. I have personally come to not like apps2sd, but I am including it for those who use it.
The reason I don't like it is because it puts your phone at a huge risk of having problems once anything goes wrong. If you install a program that causes issues, a nandroid backup will not resolve the issue because the application is installed on your SD card not your phone. If your phone starts going crazy as reported here and here, then even just a restore possibly won't fix it. You might need to go as far as to wipe your SD card too. If you are lucky enough to have a restore fix your problems you will still need to reinstall every app, even if you didn't wipe your card. And on top of that when you try to reinstall any app it will think it's still installed, even though you restored your phone. But when you click "uninstall" it will just freeze half the time because there's nothing on the phone for it to actually install. I have also read many threads that say if you happen to boot the phone up without the SD card in then it will screw everything up.
So now maybe you are wondering why I would add Apps2SD support in this rom. In order for people who are currently using Apps2SD to upgrade to this rom I must support it or require them to do a hard reset before coming to fresh. Clearly I don't want you to have to reset so I have supported it. With that said: I personally recommend not using it. This rom will auto-use it if your SD card is formatted for it (fat32+ext2+swap partitions) but it won't use it if you are only partitioned as 1 fat32. My suggestion is to stick to the 1 partition and let your applications install on the phone. Linux is not like Windows in the sense that it will run the same whether you phone has 140 megs free of storage space or 10 megs free. So unless you plan on installing 100 apps, I don't see the practical purposes of using Apps2SD. But a lot of people like it.
Now with all of THAT said -- this rom officially has and supports Apps2SD. It is a program that I think has the possibility of being great, but has to work within the confines of the phone which means tricking Android in to thinking that the applications are installed on the phone when they aren't. That is what leads to all the problems mentioned above.

If i have apps2sd already from the previous rom i don't have to re-do it for the new one correct?
no you dont.
using apps2sd2 problems
I followed all the instructions here http://forum.xda-developers.com/showthread.php?p=5618439#post5618439 for apps2sd2 yet when I open the app, it STILL says Oops, you have to run through the tutorial to set it up. I've DONE THIS. I'm extermely frustrated. I have no idea what more to do. My sd card is partitioned correctly. I've run all the commands listed in that tutorial. PLS HELP! Also all my apps are showing in /system/sd/app AND data/app. Is this correct? Why won't Apps2sd2 work for me? I really need some troubleshooting help.
I have a rooted CMDA HTC Hero using the Fresh ROM. Also is there a way to still get Sprint TV using this ROM?
Fresh .7 doesn't support A2SD, only Fresh 1.0 & 1.1.
I put this short guide together because I tend to see a lot of confusion regarding what a "wipe data / factory reset" does to your phone.
These are the steps you should take before loading a new ROM:
1) Download your new ROM and relevant supporting or needed files like modem, alternate kernel, etc., and place them on your internal SD.
2) Backup your applications, settings, messages, etc., with a backup tool like Titanium Backup, image specific backup tool, etc.
3) Boot into recovery and run a “wipe data/factory reset"
4) Follow the developers ROM loading instructions.
When you perform a “wipe data/factory reset” the content of the following directories are deleted :
/data
/cache
/datadata
/sd-ext
/sdcard/.android_secure
Nothing else on your SD card (internal or external) outside of these directories is modified so it is safe to leave files outside of the above mentioned directories without fear of losing them. Your external SD card and SIM do not need to be removed. The goal here is load a new or updated ROM in as much a clean environment that you can. Files left behind in these, especially cache and davlik-cache can cause some of the strangest problems. The kind that nobody can really resolve.
/cache - This is the partition where Android stores frequently accessed data and application components to make these, as implied, respond much faster as well as faster to retrieve / access.
/datadata – This directory contains the library, database, user specific configuration files as well as log files for its specific application installed in the /data directory.
/data directory is where your contacts, messages, settings and apps that you have installed go. Wiping this partition essentially restores it to the way it was when you first booted it, or how it was after your last custom ROM install.
If your ROM uses an /sd-ext partition on your SD card for data storage your /data directory is mapped to /sd-ext and wiping the /sd-ext directory will result in losing your data.
/sd-ext is used for apps moved to your SD card. Your Android OS runs natively in an ext format while your SD card has a fat32 format, which is used typically for USB storage devices, Windows computers, etc.
The sd-ext partition is an additional partition on your SD card that acts as the /data partition when used with certain ROMs that have APP2SD or data2ext enabled. It is popularly used on devices that have little memory allotted to the /data partition. A misfortune that in my experience, Captivate does not partake in. Still, users who want to install more programs than the internal memory allows can take advantage of this partition and use it with a ROM supporting this feature.
The folder named .android_secure is where apps are stored when you perform the "move from phone to SDram/SD card" operation.
Consider this, Apps2SD uses the fat32 portion of your SD card, which is obviously limiting because it isn't Androids native file system. However, if you format your SD card, or partition a part of it as a ext file system, you can trick the phone into thinking it's part of the Android OS native environment. This will allow you to move applications, widgets, even cache and davlik cache over to it.
Disclaimer! I am not responsible for any damage you may cause to your phone or SD Card if you try to enable/use sd-ext.
To enable sd-ext in ClockWork Mod (ROM Manager):
Boot into CWM
Go to Advanced
Then to "Partition SD Card"
Choose an sd-ext size
Then choose a swap size, or not. Swap is just like windows' virtual memory. The system will use it when you're running low on RAM and use it as temporary RAM storage. This is where you'll probably see an increase in speed.
Just for fun I put sd-ext at 512MB and Swap at 64MB which is probably more than plenty for the swap. The swap will assist a little with memory and with the extra space I can move my apps over to it with a program like App2SD or in most custom ROMs nowadays just use the "move to USB" option in "Manage Applications". Titanium Backup will also move apps to SD for you and I'm sure you can find plenty more in the market.
You can also use a tool like Minitool Partition Wizard:
1. Open Minitool Partition Wizard
2. Delete Existing Partition from SDCard (Backup data first!!)
3. Create Fat32 Partition
Note: Set all partitions to PRIMARY (Steps 3 - 6)
4. Create EXT2 Partition (System) about 150MB-200MB depend on ROM
5. Create EXT2 Partition (Data) about 150MB-250MB
6. Create EXT2 Partition (Cache) about 50MB
Personally I don't see a need to do any of this on either of my Captivate phones though I have played with it on my DEV phone.
And since it does play a big role and needs to be cleared at times...
Davlik-Cache - dalvik cache is a program cache area for the program "Dalvik". Dalvik is a java based virtual machine that is the base for running your (.apk) programs. In order to make access times faster (there wasn't a JIT compiler installed by default until Android 2.2), the dalvik-cache is the result of dalvik doing a optimization of the running program/s. This optimization is kept so that it is then re-used every time you use your application/s. By default, davlik-cache is located in your /data partition.
No, I'm not looking for donations. Just trying to clarify things for some.
Great info, but a "guide" assists you in doing something, this is just straight info.
While I initially intended on writing it to guide flashers into the benefits of a wipe data / factory reset, and avoiding the myriad of strange issues experienced, I can see now where it can more construed as informational. Hmmm... maybe I'll add more to it or ask a mod to change the title topic for me.
Regardless, my hope is that some people get some benefit out of it otherwise I've only wasted my time.
Thanks, I've been wondering for a while what that actually did.
Great start for a guide that should clear the boards up a bit. I vote it to be stickied after adding a bit more info on backing up, partitioning the sd card, dalvik cache, etc.
I think it is important to explain that a reset should not be done after flashing a custom ROM because it deletes the Dev's settings/data/non-system apps. Instead flashers should either reset after flashing back to stock or before flashing a custom ROM over the current custom ROM.

If you plan on trying several different ROM's and/or updating your favorite ROM every time a new version is released you need to invest in an application like Titanium Backup or one that comes with your ROM if it's supplied with one. MIUI includes one that works extremely well. Performing a “wipe data/factory reset" after loading your new ROM and before booting into it should provide you with a smoother transition to your newly chosen or upgraded ROM. Having a standard backup and restoral process should help you enjoy it quicker too.

Here is something I keep in a word file to help answer what you are also trying to answer. It is a bit shorter and simplified but it may help to polish your thread for us simpletons.
Dalvik cache is a place where the Android OS re-compiles the executable programs the first time to optimize them. It does this when you make a major change like replace the kernel/modem. Clearing the Dalvik cache will force Android OS to recompile the apps for the the new kernel/modem. This can take time on the first boot after clearing the Dalvik cache.
Also the main data Cache is used by the Android OS at run-time to write temporary files for specific reasons. You want to clear this out so it doesn't re-use the old cached data.
Manually clearing both caches allows the new kernel/modem to be installed in a "cleaner" environment. It's just preventative maintenance.

That is much more boiled down. I looked back at the "how to flash" threads and a couple good explanations on custom roms. None explain this that I found.
Cosmo, here are some more thoughts on misunderstandings I have had and seen posted. Like post above I pasted from my notes, so may be incorrect.
Bootloaders: Same for Froyo/Eclaire in both i897 and i9000 roms. GB requires new bootloaders, but i897 are apparently cross-compatible. However, issues seem to pop up on i9000 roms with GB i897 bootloaders. If flashing back to Froyo, use the full jf6 stock, not cezar's stock eclaire without bootloaders.
Using Tibu: If no useful data (i.e. Bookmarks on dolphin) then simply click data only when restoring user apps. Typically no issues when restoring user apps after switching Android versions. However, system apps should not be restored because of the rom customizations. Especially when switching to GB because it uses different directory structure. I do not seem to have issues when staying on same version and restoring foreground (user accessible) apps with data only or restoring green text color sys apps with Tibu as icon (i.e. Accounts).
Rom manager: really only need the app if flash to stock and need to flash rom directly from cwm. If so, then flash cwm (top button in menu) and choose phone. This places update.zip in /sd, which is opened after selecting "reinstall update" in stock recovery. Usually have to select it twice for it to work. This will replace ATT stock 2e recovery (blue text) with cwm 2.5 (froyo).
Voodoo color, lagfix, sound: must either be included in kernel. Lagfix simply allows user to format sd as ext4 (linux). Color balances display so less blue iodes are used and color is more realistic. Sound allows clearer sound through headphones through tweaks enabled in voodoo app. If sound is not in kernel then purchase voodoo pro in market and it will install it into the kernel (if rooted, even if stock).
Thanks for clearing that up!

Really, really useful. Had no idea partition options were available to this extent! Especially swap. By mini tool are you referring to Easus' program? I am definitely checking this out tonight. Thanks!
Great guide. In order to clear
/sdcard dir I master clear it after flashing to stock. Is there an alternate method besides deleting dirs myself?

That is probably the safest way to do it within the phone itself. An alternate way would be to mount it to your computer:
In Windows right click the drive that was assigned to your internal SD card and then click on format. By default it'll most likely set you to Fat32 and if you click format it'll say its complete, but nothing will be deleted. Android being a Linux OS doesn't use fat. You can format it by choosing exFat, but by doing this...
!!!WARNING!!! be aware that you will lose everything on your internal SD card AND your external SD card.
Emphasis placed mainly for others that read this and might not know.
Safer and easier to do it within the phone.

This one is from MiniTool, though I wouldn't be surprised if Easus owned them. I didn't investigate to confirm. You can get the free home edition of MiniTool Partition Wizard here.
Very nice infos. Deserves a sticky, although, probably in a different thread.
Some information on what "Master Clear" in Odin would also be helpful - I have never trusted my phone to 'truly' clear everything on the phone, I have found the Odin Master Clear option to be much more complete.
It is a bit odd, I do this with my PC every six months, I back everything up and format the drive and start over again (after running Spinrite on all the drives) - I do this on / around New Years and again over 4th of July weekend and I decided this past weekend to also do the same with my smart phones (4 Cappies) and tablets (Ipad and 2 Android tabs) this past weekend.
It gives me that sort of squeaky clean feeling and seems to make my devices run smoother. Maybe its all in my head, dunno *shrugs*.
One thing I can say however, I have not had a hard drive go bad on me since I started the Spinrite thing 10 years ago (I still have an 8 GB hdd in my desktop that is working!!).
Any decent update(r)-script will do this for you.

I can run some tests on Odin's master clear to confirm what it does. Initially I would believe it does the same as a "wipe data / factory reset", but testing should let us know for sure. I'll test it this weekend. Maybe sooner.
Awesome to hear that I'm not the only advocate for SpinRite and I still use it a lot though not every 6 months like you do. It's definitely worth having and using.

I totally 100% agree with you, MikeyMike01. Unfortunately, not all update scripts are created equally Asides from teaching people how to script themselves or parse through it, a task I do not have the time or patience to tackle, this it probably the easiest and best way to have users try to avoid the many and strange issues posted that possibly / most likely could've been avoided by using the tools at their disposal.
On a side note... I didn't notice you got yourself an Infuse 4G. Congrats! How do you like it? I've been out of contract for almost a year now and wouldn't mind upgrading (my wife is in contract), but I haven't seen anything really worth upgrading to or that does something I really need/want that the Captivate cannot, atm. I haven't looked up any specs and reviews on the Infuse yet tho.
I'm running the **SMS* 3.02 by RSK team on my HTC Desire, the rom works great (I wanted the Amaze Cam) but I seem to run out of internal memory really quickly, ROM has only been on (again) for a week and I'm down to 25mb, all apps have been moved to SD.
I do have quite a few apps installed, but surely being on SD internal memory should be empty. The phone has a 16Gb SD card with a 2Gb ext partition created through recovery.
How to I get the memory back? I suspect it's going to be full in a day or 2, leading me to another full wipe
What i did to make more mem is using ''ram manager'' on the market and kill apps running in the background.
Thanks, I'm not sure how killing running apps is going to free phone storage space, though
I suspect I need to find a data2sd rom, ideally with the new cam
getting closer, I notice my Dalvik cache is ~170Mb, so taking up all that space. I installed 2 market apps to move it, the first, S2E just does nothing when IO tell it to move the cache. The second, a2sdgui, exits with the following message
"cannot start for one of these reasons
1. your phone is not rooted (it obviously is to be running custom roms?)
2. A2SD scripts could not be found o
3. No EXT partition found
Did you create a partition on your SD CARD? Does your custom rom support APP2SD (normally is natively included)?
Make sure.
Otherwise, I would suggest to try another rom to see what happen.

Don't assume that because you are running a custom ROM means your phone is rooted - the 2 have absolutely nothing to do with each other. Check that you have superuser installed, and if you do run terminal emulator and type the command su. If you're rooted you should get asked if you want to allow superuser privileges to the app. If it doesn't ask then either you've allowed (and remembered) the permission before or you're not rooted.
If an app's telling you you're not rooted then it's possibly right - always good to be sure.
Thanks, phone definitely rooted, and superuser installed (and titanium backup, which I've just used)
can't see mention of apps2sd on the rom page, though I was running a pretty old version.
Decided to do a full wipe, repartition the SD card and install a later version which has dalvik-cache to sd-ext, hopefully this will solve the problem of it filling.
Showing 174MB free right now, (+8.6Gb)
I take it if the cache does fill again I can just wipe it with no ill effects?
I wipe all my cache periodically with this:

I normally free up to 20 MB.
Hi There
Can someone explain what he\she did to partition SD card, and make all apps get installed on it.
Please note :
1. I don't want to use Titanium backup for this usage. I don't have the paid version and I'm tired of doing this one app at a time.
2. I saw some guides on the net, but they were all for GB.
(partition the microSD on PC using minitool) -can we use ext4 on our MTD ROMs ? What is the 1st partition for ? and the 2nd ?
(install busybox and super user) - Is it still needed ? (MIUI for example has LBE as su).
(install Link2SD) - Is it always in memory ?
(reboot and put partitioned SD card)
(Define Link2SD)
3. I also saw swapper instructions but I can manage with 170MB free RAM memory I get after removing all unnecessary system apps, and I remember ppl saying then that it kills the SDCard very quickly.
If someone has a clear guide or instructions that he knows work, that will be nice.
Thanks in advance.
Step 1. Partition your SD card to have a sd-ext partition. This can definitely be ext2 or FAT16. Anything else depends on your kernel. Most of them do support ext3 and 4, but... start with something fairly basic.
Regarding recoveries:
TWRP has always failed for me on this, so I'd avoid that.
This may be doable in CWM. I've seen reference to that newer versions of CWM removed the partition option, so you might need to flash an ICS ROM with an older kernel, repartition, and then flash back to the one you want.
Also note that if you use CWM to repartition, your SD-card will be wiped. So do a backup first.
Step 2. Install Mounts2SD. Either from XDA or the Play Store. Even if you do take it from the Play Store to get update notifications, I highly suggest grabbing the recovery script from the XDA thread so that you can get back your shifted applications without needing to re-download and install M2SD, since it likes to be on internal which means... shifted off.
Step 3. Open Mounts2SD. Grant SU rights at whatever point it asks for it during step 3. Hit the menu button. Go to Application Settings. Install the Startup Script. Tell it to use the built-in busybox as well, so that you don't need to install anything or worry about it failing. Back out of the Application Settings.
Step 4. Press on the Wrench to go into the actual specific settings. I currently have forced Cache, 1% Storage Threshold, Applications are the only bit moved, the File System Check is on and using the Ext4 Driver, 128KB Deadline for Internal and 4096 with Deadline for External, and Safe Mode is disabled. But decide on what you want yourself, set it, go back to the Eye to see your current info.
Step 5. Reboot.
Step 6. Wait 1-30 minutes for it to finish moving all your stuff around.
Step 7. Unlock your phone, open Mounts2SD, and make sure everything looks pretty on that first 'Eye' info tab. If you like it then close Mounts2SD and keep going on your merry way. If you don't like it or you've done something like offload your data and now your phone is wretchedly slow, go to the Wrench, change your settings, go back to the Eye, and reboot again. Repeat until satisfied.
I thought it would be simplier.
A few more questions:
1. If I partition SD on PC, then I don't need any partitioning on recovery so it should work fine even on TWRP or advanced CWMs. Am I right?
2. Why do I need scripts for? Isn't the app enough?
3. Why should/could it possibly slow down my device? TB 'move to SD' for all doesn't slow my device what so ever.
4. How and where do I see what partition is used for what?
5. How much RAM does the app take?
6. Have you tried other apps link2sd or something CM has built in I think.?
Thanks.

New answers to new questions.
1. Skip step 1 if you've done it on your PC. I just suggested recovery as that's easy... if you've made your sd-ext partition on the PC, step 1 is done.
2. No clue on Link2SD. I use Mounts2SD instead since it lets me set things. It probably does the same thing though and sets a init.d script that gets run during startup.
3. True. For some reason though having all your data moved to sd-ext makes our phone go to a crawl. Same if you move off the dalvik.
4. That's in Mounts2SD. No clue how you can see if you're using Link2SD.
5. For Mounts2SD, none while it's being used, since it just runs as a startup script. The app is just to control the script.
6. Not successfully. I had tried 5 or 6 different apps back a year ago or so when I first started playing with sd-ext and Mounts2SD was the best and free, so... never looked back after that. Now you can also do some system-flag tweaking if you want to donate, but the sd-ext stuff is all free.
I was able to successfully partition SD and use mount2sd on 4.3 SlimBean.
however, it was rather slow.
CM 10.1 and CM10.2 by DJL. did not allow me to partition nor did they recognize SlimBean's partition even if I replaced them kernel (to NilTMT).
I'm currently using CM10.1 which is stable as a daily driver and manually swapping apps with TB, I hate it, but this is the best combination I've come so far.
I sold my wife's SGS4G and upgraded her to SGS3 and hopefully in a year I will do the same. it had its moments, but on the bottom line it's a pretty ****ty phone with its lack of internal mem...but hey, it drove so many of us to go deeper and deeper trying to understand and made us more tecnolgical and solution oriented.
Mounts2SD worked for me on CM10.1, so not sure why it failed for you. Ah well.
A few things I have found...
Yes, you can partition on Windows, but you're really asking for trouble. It's not too bad download Ubuntu or the like and you can boot off a USB stick without touching your Windows install.
The TeamAcid kernels that I know of handle ext2/3/4 file systems. All kinds of arguments as to which are better. I personally use ext4 and don't find it obviously "slow" for the way I use my phone.
That said, what the boot scripts (which are part of a flashed "kernel" for the SGS4G) actually do with a "special" partition is another story. In some cases the first stages of booting will look for special partitions and mount them in pre-configured places. For example, the second partition of the removable card might be mounted on /sd-ext/ in many CyanogenMod ROMs. Many (most?) SGS4G ROMs don't have these "special" mount rules defined.
Moving an app to SD using the "native" approach just moves the app and none of its data to the SD card. It won't for example, move 25 MB of mail from /data/data to your microSD
Moving an app to SD (or anywhere else) doesn't keep it from generating its classes in /data/dalvik-cache -- It isn't "free" to have an app on SD as far as internal storage goes, even if it doesn't write any data.
Moving an app to SD will absolutely slow down your boot time. It does it by creating a file that contains a file system that then gets read and mounted at boot time. You can watch the parade of them getting mounted using adb logcat. It can take a minute or two to mount them all. Once mounted, that double layer of file systems shouldn't slow you down too much, since it is basically a read-only kind of thing.
Scripts are required since you need to be able to "fake out" the operating system as to where things are stored for anything (except if you just use the native app to SD method). In most cases you need new partitions mounted before the Android part of the OS starts running.
Some scripts are more robust than others.
TitaniumBackup (paid version) has a way to move data to an external partition. It works like a charm for me (64 GB Sandisk UHS-1 / Class 10 microSD). It was very tweaky for me to get it to recognize the ext4 partition the first time. It can bulk-move app data to the partition. I don't know which, if any, of the other scripts move the data to an external partition.
On my phone, an ext4 file system can be significantly faster than the internal yaffs, especially for write. Alas, it usually seems to be read that is a killer for most things in an well-written app. On my phone, yaffs can be faster than ext4 for short reads. Who knows how this would play out in real-world usage.
Other things that TitaniumBackup can do that help free up internal storage, at least in the paid version, are:
Dalvik cache cleanup
Integrate system Dalvik cache into ROM
Integrate update into ROM
Convert to system app
I can confirm Link2SD works where Mount2SD fails, which is an ext3 partitioned sd-ext on AOKP. it doesn't get any simpler than that.

I just started getting into rooting and such. I'm experimenting with kingroot at the moment and it seems to be working but I still can't seem to uninstall things.
I have a Samsung illusion and a moto G .I'd like to do custom roms but really all I want is to free up space. Please help

I can tell you are new here. It might be a bit confusing to you for now, but deleting system apps does NOT increase available space for games.
On the phone memory there usually around 5 or so paritions. Partition is basicly a part of a hard drive/SD Card. It is used for organizing files into volumes. Android phones usually have the following partitions: /data /system /sd-ext /sdcard /cache /boot and a few others depending on the brand.
The apps you download are stored on the /data partition and system apps are stored on the /system partition.
So deleting apps from the /system partition will free space in that partition only and the /data partition will stay exactly the same size so you won't get any additional space.
You could however resize /system partition and add that to the /data partition which is not only very dangerous, but might actually break your phone forever.
The best solution is using an external sd card.
Or even better, mounting the internal sd card to a folder on the external card. This means that the phone will think it's putting files on the internal sd card, but actually it's putting them on the external card.
Some apps that can do this:
Link2SD - Very nice UI, a lot of features ; Requires advenced partitioning of the external sd to work.
GL to SD - Very simple, almost always works ; to open apps that are moved you have to run them from gl to sd app
FolderMount - Works very well, just mount the apps and never need to think about it again ; A bit complex to use for an average user, outdated UI
NOTE: All of the apps may cause app loading problems and files in weird places. They may also corrupt data files but that hapends extremely rarely and only if the user did something wrong.
Well geez that's a bummer. And the moto g unfortunately doesn't have an sd slot. Even IF I can't increase download space, I still want the phone to run faster and as we both know there are junk apps that run in the background needlessly. Can you still guide me through the process to optimize functionality etc.
Thanks so much for responding
The motoG is actually running slower. I'm not seeing the point in going through all this trouble if I can't free up space and have a smooth running device.

for removing junk apps you need to use titanium backup.you can get it from google play store.by using it,you can uninstall junk pre loaded apps from your android device(s).
