[Samsung Galaxy Mega] unclefab:
FOR ROOT USERS ONLY

Tested on Mega I9200 XXUAMEE

I removed more than 100 system apks, and my Mega works like a charm.

You will notice that the google apks are missing, and that the video player, music player, file manager etc. are missing as well, I removed them because I don't like the way they spy on us and suck our private data (look at the permissions they have if you don't believe me). No worries, just keep on reading for some alternative apks, and some ways to prevent spying...

IMPORTANT

1-Before to start the delete process do a Nandroid back up, and do a back up of your system/app folder (where all the system apks are) in case you want to reinstall a specific apk later.

2-If you decide to uninstall the filemanager apk, install first an alternative file manager, like let's say ghost commander, because if you don't then you won't have any app anymore to navigate to your files after having uninstalled the file manager, pretty obvious.

Same story with the launcher, or you will get a bootloop.

3-After you uninstalled all the apks do a cache and a dalvik cache wipe.

4-Reboot and enjoy full speed and no lags!!!:good:

5-Go to the data/data folder and erase the folders from the removed apks (optional), or use sd maid or whatever similar apk to do it for you.

IMPORTANT 2

Do not mess with system apks if you don't know what you are doing and if you don't know how to get back to the beginning in case things go wrong.

I won't take any responsability for any damage caused to your phone.

All what I mention below has worked for me but once more, do not play with your system unless you know how to recover if things get out of control:eek:.

SAFE TO REMOVE APKS

Rather than giving a list of removed apks I will list here the apks I didn't remove, so that you can assume that any apk that is not on the list is safe to remove. I do so because it's faster to list the remaining apks than the removed ones...

So here are the apks I kept (I have to admit that it's a bit extreme, and you are of course not obliged to keep so few apks, but at least you'll know which ones are safe to remove):

-csc

-defaultcontainerservice

-flashbarservice (removable if you don't want to have the static multi windows function. By the way I made a mod to enable floating multi windows that doesn't need the flashbar, you can find it here : http://xdaforums.com/showthread.php?p=48000697#post48000697)

-fusedlocation

-hybrid radio (removable if radio is not your thing)

-jobmanager

-logsprovider

-minimode-res (removable, but I kept it temporarly for testing purposes on the above mentionned floating windows mod)

-packageinstaller

-samsungcamera (removable? It seems that if one removes it then alternative cameras don't work, but I haven't tried them all)

-seccontacts

-seccontactsprovider

-sechtmlviewer (removable and replacable by an alternative html viewer, but since it doesn't spy and since it works well I kept it)

-secphone

-secsettings

-secsettingsprovider

-sectelephonyprovider

-stk

-systemui

-vpndialogs (removable, but then no more vpn)

-wlantest

Note that if you delete mediaprovider you won't be able to change your ringtone and your notification tone anymore (not a big deal for me but I don't know for you), and you will be stucked with the default tones. To change them manually you'll have to open the res/raw folder in framework-res.apk and add your own tones, not a big deal.:D

ALTERNATIVE APKS

-Launcher:

holo launcher hd, or whatever launcher you like, but install it before you uninstall touch wiz!

-Keyboard (Samsung ime):

I use the modded Xperia keyboard but there are many others.

SMS:

go sms, or any sms apk you like, choices are plentiful.

-Bluetooth:

if you use it for speakers or headphones keep it, but if you use it only to transfer files then uninstall it and use fastfiletransfer (the best, it works without wifi connection) and/or any ftp app (like swiftp for example, but such apps require an active internet connection) instead.

-Video:

mx player or bs player (the two best ones to my opinion) + floating player (basic video player but it boasts a resizable floating window, handy if you want to watch something while doing something else).

-File manager:

ghostcommander (dual panel mode, root browser, customisable toolbar),- or totalcommander.

-Music player:

I like gone mad music player but there are one zillion other options.

-Browser:

opera mini for speed, mozilla firefox for full desktop experience, and dolphin mini for something in the middle. Chrome? No thanks, the least google stuff I have in my phone the better I feel!!!

-Gallery:

quickpic.

-Polaris (pdf reader):

moon reader or mantano.

-Edit documents (doc., docx. etc.):

office suite or kingsoft office.

-Alarm:

any alarm clock apk will do, there are heaps of free ones...

-Google Talk:

lillypad hd.

-Gmail:

any email apk will do, otherwise access gmail from opera mini browser, it's faster.

-Play Store:

aptoide (there are others, see which one fits you the best).

Google Now:

actually you can keep that one if you like it, it's a stand alone apk which means that unlike gmail or gtalk apks it doesn't need the full google framework to work.

-Google maps: maverick (but there are others), google earth (stand alone apk, and not too much on the spy side).

-Clipboard:

clipboard contents.

-Calculator:

aircalc (floating calc).

-Quick Notes:

floating stickies.

-Bonus:

greenify (try it, it hybernates apks and saves juice).

That's all what I can think of for now. You are of course free to ask if you need anything but remember, most stock apks are replaceable and a quick internet search will show you plenty of alternative apks.

Last part, how not to be spied...

Some of the alternative apks I listed above do have abusive permissions, and so have the remaining system apks. To prevent your personal data to be sucked and sent who knows where you need four apks, namely:

1-Rom Toolbox Lite (free) or Pro (paid),

2-Privacy Blocker (paid),

3-AFWall+ (firewall, free),

4-Xprivacy (free).

-First open Privacy Blocker. Scan all your third part apks one by one, and see their dirty little secrets. Then mod the ones you don't like, it's easy, just follow the onscreen instructions.

-Second, open Rom Toolbox. Block adds, prevent any apk from auto starting, disable any transmitter you don't like, and try some build.prop and kernel tweaks if you feel like it (but be careful and do not play with your build.prop and your kernel unless you really know what you are doing).

-Third, set your firewall for wifi, 2/3/4 g, vpn, wlan and roaming with AFWall+.

-Last but not least, install the ultimate protection, Xprivacy:
