FAQ

  1. Why not all apps can be moved to the external storage?

    Beginning with Android 2.2(froyo), developers can allow their applications to be installed on the external storage (for example, the device's SD card). This is an optional feature developers can declare for their applications. If developers do not declare it, their applications will be installed on the internal storage only and it cannot be moved to the external storage. If you find any non-movable apps, please kindly email developers (not us) for details.

  2. What is the app cache? Is it safe to clear them?

    The app cache storage is used for applications to cache some data. When the device is low on internal storage space, Android may delete these cache files to recover space; hence it is safe for you to clear the cached files manually. The "Clear cache" function may not work for your device. Please send us the phone model, Android OS version information if this function does not work on your device.

  3. Can all apps be installed on the external storage?

    If app uses any of the following features, it cannot be installed on the external storage. It's required by Android system.

    App Widgets, Services, Input Method Engines, Live Wallpapers, Live Folders, Alarm Services, Account Managers, Sync Adapters, Device Administrators

    You can add apps to the ignore list if you don't want to move them to the external storage.

  4. Will it auto install my apps after switching to a new phone?

    This app is not used to backup apps to SD card. It only helps you to move a portion of apps used space to SD card. You have to manually install the apps after switching to a new phone or perform a hard reset.

  5. Failed to upgrade apps that installed on the SD card, or move apps to SD card?

    Please first make sure that you are not connecting your phone with PC as an USB disk, then try to upgrade or move the app again. If you still get the problem, it should be caused by the bug of Android system. Please follow the instructions below to fix it (WARNING: These instructions are for advanced, technical users only, use at your own risk):

    For Windows users

    1. Mount the device's SD card on your computer via USB
    2. Open the drive for the SD card in Windows Explorer
    3. You should see a ".android_secure" directory, open it. If you don't see this directory, right-click in the Window and choose "show hidden files" (or something like that)
    4. Delete the smdl2tmp1.asec file in the directory. DO NOT delete any other files you see in the .android_secure directory, you may end up deleting your applications and other associated data

    For Mac users
    1. Mount the device's SD card on your computer via USB
    2. Look in Finder to see what the SD card is called, often it is called "NO NAME", for our purposes we'll call it $NAME
    3. Open a Terminal (Applications > Utilities > Terminal) window
    4. Type "rm /Volumes/$NAME/.android_secure/smdl2tmp1.asec" REMEMBER: Replace $NAME with the name of your SD card from step 2. If $NAME has spaces or any character that is not a number or letter, it should be replaced with that BACKSLASH and a space, eg. "/Volumes/NO\ NAME/.android_secure/smdl2tmp1.asec" or "/Volumes/I\ said\ \"OH\ HAI\"/.android_secure/smdl2tmp1.asec"

  6. It takes time to list apps on startup. Can you improve it?

    It can be improved by saving apps information. We don't want to take this approach as it needs the extra phone internal storage space for saving the information. We keep improving the loading speed by using another approach.

  7. Do I need to ROOT my phone to use this app?

    No, you don't. This app supports either non-root or root Android v2.2+ devices.

  8. App icons disappearing from home screen after devcie rebooted

    It's the bug of Android. You can fix the problem by re-mount the SD card.

  9. I have two external storages, App 2 SD only moves apps to the internal USB storage.

    Moving app to SD is handled by Android. App 2 SD app only provides an UI for you to manage it. Currently, Android only supports the primary external storage (i.e. internal USB storage) for App 2 SD. If you have two external storages, the external SD card usually is the secondary external storage. Android only moves apps to the primary external storage.

  10. I cannot find the "Move to xxx" button from application detailed information window.

    If the device does not have a real primary external storage or the primary external storage is emulated. Moving app to SD function will not be supported by Android system. It's the limitation of hardware. Please get more information from device manufacture.
