Deleted system app and internal storage does not reflect?

    I just rooted my phone. I have an LG ally 2.2. It went pretty well, but I am quickly realizing some things.

    First of all, just cause my phone is rooted, does not mean I can go and uninstall any application using the same method as before. I had to download a "root uninstaller" app. Anyways, once I did that, I removed a system app that was around 10MB, but my internal storage did not reflect it.

    I did restart my phone, and still nothing. I have no "custom ROMS" or anything like that.

    If anyone could help me get an idea of why this is that would be great...and any other advice and general points would be great.

    Thank you!

    the same thing happened to me, i deleted "thinkfree" and my internal storage stayed the same but it feels like my phone is faster

    Removing system apps will not increase your internal storage space by as much as the size of the app because the app itself is stored on system storage space not internal storage, but you can regain some of the space by going into recovery and clearing your cache and dalvik cache (don't clear data).

    flyinjoe, thank you, thank you, thank you!!! I've been wondering why my internal storage space was so low and I was constantly having to delete apps so I wouldn't get that LOW STORAGE icon in the notification bar. I didn't realize I could wipe dalvik cache and gain space. I did that and went from 15mb to 54mb!!! Thanks a million!

    What is "dalvik" cache and how do I delete it? And yes, I know what cache is, but not "dalvik cache"....nor how to delete that cache...

    Any direction would be greatly appreciated!

    Dunno what dalvik is used for specifically, but to wipe it(if your rooted), reboot to recovery, scroll down to and select the "wipe" option, then scroll down and select the "wipe only Dalvik cache" option, confirm the selection when prompted, then back out and reboot.

    Simple explanation someone else wrote because I am lazy:

    You can wipe it in recovery, or in a rooted terminal
    Code (Text):
    2. rm -r /data/dalvik-cache/*
    Or if you only want to remove the dex for a specific app like Maps:
    Code (Text):
    2. rm -r /data/dalvik-cache/*Maps*

    Since your Dalvik-Cache will rebuild when your phone boots up the only time you will save space by wiping dalvik is if you have uninstalled or deleted apps and there is still dex files left over. After I install a new rom I always fire up a terminal and remove all the applications I dont want/use and then wipe the dalvik.

    Wiping dalvik without having just uninstalled application will do nothing. It will just make your phone take a long time to boot afterwards, as it will have to rebuild the dalvik, it wont hurt, but it wont help either.

    Awesome! Thank you guys so much. When I uninstall a program and clear the dalvik cache for it, it gives me almost all the space back!

    Your welcome guys. BTW, if you are a person who installs\uninstalls a lot of apps, I suggest you make a regular routine out of wiping these two caches on a weekly\bi-weekly\monthly basis depending on how many apps you actually try. Android is horrible at cleaning itself up when an app is removed and you lose space that is not even being used by anything.

    So, it definitely will not hurt my phone to delete ALL the cache in that folder and will just recreate them if needed? I have to say, even though I am only deleting the cache from the uninstalled program, it free's up the same amount of space that application took on the phone. But, I guess the cache isn't included in the size the phone reports the application as.

    How come when I uninstall the program with a root uninstaller, it doesn't actually remove it and free up the space?

    I hate it when I forget how to do certain things. Can you refresh my memory on how to properly reboot my EVO into recovery so I can wipe my dalvik cache? Thanks.

    Never mind. Dummy me finally remembered.

    As someone who's a relatively new EVO and Android user--got my EVO in October 2010--I have since then installed and uninstalled many apps. I rooted my phone in December. During this time, I have never wiped my Dalvik cache but did so today. So, based on your explanation above, I would have thought that I would have recovered some internal memory, but it doesn't seem like I have. In fact, it appears I've pretty much recovered NO additional memory.

    Am I doing anything wrong, or might I perhaps have not properly wiped the Dalvik cache? I hope it's the latter, but considering I think I followed the directions correctly on how to do that, I'm doubting the fault lies with me.

    You may be able to get answers to your EVO questions faster by posting in the EVO forum instead of here in the Ally forum HTC EVO 4G - Android Forums

    I'm so sorry but can you explain how to go to recovery and delete dalvik cache, because I unistalled the system apps I didn't need and I still have only 13 mb internal memory out of 138 mb. I only have like 6 apps, and they are small ones.. Please anyone help! :/ I tried a couple of things but nothing helps...:(:(:( PS. My phone is Alcatel One Touch 985...

    Set up the Android SDK

    Android SDK | Android Developers

    Using Hardware Devices | Android Developers

    Once you get it set up just connect the phone to the computer via USB. Open command prompt or terminal and issue the command: [HIGH]adb reboot recovery[/HIGH]This should get you into recovery. there's also a way by pressing this button and that button at once but I don't remember the combination.
