  • HP 7 G2 Dose does not install apps on SD card

    I recently that Got a HP HP TAB 7 G2 and it dose not allow me to install apps on SD card.

    I have read and found that Android 4.4.2 dose does not install apps on SD card on HP tabs.

    Y at - it another way I can do it, or I can hope an update or update Android 5.0 will allow me to do.

    I like to play games on the TAB and can install only 1 or 2 big games due to the lack of internal memory (4 GB).

    Any help would be greatly appreciated.

    Hey @ApoorvMishra ,

    Welcome to the HP Forums!

    I understand you are trying to install apps on your SD card instead of internal storage.

    Unfortunately, this is not a feature available on any Android device that does not have root access.

    There are methods available, but most require rooting the device, or by using the APKs HP could not support or encourage.

    Thank you.

  • Apps, no download or update

    I've recently updated to iOS 9.3.1 and dicoveref that my apps cannot download or update. If I click on 'Update' or 'Get', the application will be displayed as "waiting" on the home screen, but will not start to download. I rebooted my iPhone several times without success. It's a 5s iPhone that has about 2 years.

    Try to reset the App Store:

    Close the App Store completely from the window of the selector app by double clicking the Home button and slide up the App Store preview pane until it disappears from the display. You may be able to pick up the tab App Store covering scribbles to the left.

    Then sign out of the iTunes Store (in the settings).

    Then perform a forced reboot. Hold down the Home and Sleep/Wake buttons simultaneously for about 15-20 seconds, until the Apple logo appears.

    Then reconnect to the iTunes Store.

    Also try by going to settings > general > Restrictions > and make sure that iTunes Store, Apps install, delete the Apps and In - App purchases are all under the section allow. Try to install again.

  • After downloading the updates, I can't reboot my pc, so now I can't receive updates.

    After downloading the updates, I can't reboot my pc. I code pops up that says that if I end now that I'm going to lose all unsaved data. So, I can't log out or restart without losing my updates. I can't get my active X to work now... I can't download it because it requires a reboot. Help!

    Hi stevenstar,.

    a. you just download the updates of Windows or you have installed them as well?

    1. at this point of time you can cancel the reboot and back up all your data and close all applications that are open and restart the computer to make the changes.
    Once the computer restarts view the Windows update history and check if updates are installed.

  • Updates will not install, Apps will not install Windows 8 error Code: 0x8020002e

    We have 3 Machines, we're the United States (S7 computer laptop from Acer) and 2 other desktop

    None of them are able to install windows updates, or install apps on the Store.
    I did a clean install.
    Created only a user MS (Hotmail) account
    Stop the Windows update service, deleted the files from windows update, reactivated the service and tried again. (still no 0x8020002e)
    Disabled the WSUS service on the server. And I tried to install each update manually.
    Changed in the locale and updating the time.
    Uninstalled all anti-virus and activated the default firewall.
    Ran sfc/scannow (even after complete reinstallation of Windows 8)
    Everything ran as administrator, but the updates and app downloads all fail.
    Also, met with MS support guys that they connected remotely with Support.me, and haven't found anything.

    This is not a solution for everyone in general - but we found that the problem was related to the Cyberoam firewall unit was actually blocking traffic to the store - once he was removed from the internet packets audit exceeded the updates.
