    This is AMAZING! I was just about to go looking for a thread like this, and I stumbled upon the 2012 guide you just posted, which of course linked to this. This is such a great resource!

    Great post, very useful info!

    A couple of things to note:

    CMParts, remove it, and you will have to install anywhere from 5 to 15 market apps to get the same functionality. This handles everything from lockscreen changes, to gui changes, to cpu overclocking., to how your phone's inputs function, over 50 different settings altogether. IMHO, necessary if you want to get the full use of your phone (without install other apps).

    GMail, I never install it. I just use the default email app, and enter my gmail address and password, quick and easy.

    So if I put a .apk in the /system/app/ folder before I flash, will it install automatically? Or is there more to it than that? What I'm getting at with this question is this: I never use the stock music app, I've been using Google Music for a while now. So if I were to replace music.apk with whatever the Google Music .apk is, would that work?

    It should, however, not everything is able to run from system/app. Some need to be in data/apps.

    Ah! I see! And /data/apps is part of the installed file structure, and not part of the ROM zip, correct?

    /system is installed from your ROM. So /system/app are apps that the ROM included.

    /data is not installed from your ROM, this is your data. So /data/app are apps that you installed.

    But note that /data/data holds the settings for all apps. It needs to because /system is normally read-only.

    OK, I got it now. I guess I should have read up more on the Android file system structure before hand. If I find a good tutorial on the subject, I'll post a link.

    +1 on this thread. This is an excellent guide for which apps can and can't be removed.

    Yeah, I agree. This guide is useful for all sorts of different phones. If for nothing else, it should be sticky so that those with other phones who happen upon our forum might take notice and propagate it to other forums. Good work once again LeslieAnn!

    Found out the AndroidTerm is not safe to remove as it can cause problem with flashing ROMs, and the Talk.apk doesn't effect Market but must likely well disable the Voice button.

    Edit: Nope I have a dead button, guess that is the price one pays for buying a used phone.

    The effects of removing certain apps can change depending on what version of Android and which rom you have. CM responds differently than stock, GB responds differently than Froyo.

    Great post Leslie Ann! I've always held on to the theory that you shouldn't remove ANYTHING from your phone that you can't re-install from the Market or replace with an app of the same functionality from the Market. (except for your phone contacts apk which HAS to stay). I tried to remove that once and regretted it!
    Thanks for all the guidance girlfriend!!!

    When do I remove the apks? Before install of the ROM or can I remove them safely with esfilemanager while running the phone ROM software?

    I have a question... When removing apk's from the system/app section in es file explorer, do I need to delete the .odex file as well? I'm on stock for the HTC One V for virgin mobile.

    I removed WallpaperPicker.apk through link2SD. After power-down/up the phone (Samsung Galaxy Duos, ICS) is going though the initial logo startup but the screen remains blank. Is there a way to re-install this apk through the SD card, bearing in mind that I cannot do anything on the screen? I can do a hard reset only, but am unsure if that would really take care of this.If re-instalation is possible where do I find the apk, my searches so far led me only to a zip that contains no .apk.

    Notes: The file I deleted was definitely about Wallpapers and picking, however it was not "live" - that had been deinstalled as soon as I rooted the phone. I am 90% sure of the precise name, It was the middle of the night and I couldn't sleep (bad idea to do something like this then! ). It was about wallpaper choosing though and it was a system apk, that much I know for sure.I'd appreciate any ideas, thanks

    First: This is the LG Optimus V forum.
    What works for the V may very well not work on your phone.
    The best place to ask your question is in the forum specifically for your phone. They should know exactly what you need to do.

    The following should work on your phone though:
    You need to have the Java JDK installed onto computer then set up the Android SDK onto your computer. You need to make sure you set it up with the tools, platform, and platform-tools folders. You will need to put the path to the adb.exe into your computers environmental variables.
    Put the apps you deleted into the platform-tools folder (in there .apk form). Plug your phone into the computer (make sure you have already downloaded and properly installed the USB drivers for your phone). Open a command prompt in the platform-tools folder. Some Windows OS versions require you to right click the actual folder, others an open area inside the folder to select that option (I have XP so I had to download and install the utility first). Then type in this:
    Code:
    adb install <exact and complete name of .apk>
    You will need to go to your phone specific forums All Things Root sub-forum for advice on the proper wallpaper picker.apk to install.

    Hope this has helped
