• How to fix the “Application not installed” error onan Android phone

    If you’re an app maniac then you should have encountered
    the “Application not installed” error while installing apps at
    one point or another; but, don’t get me wrong, even people
    who hardly install apps could encounter this error too.
    issue is sometimes accompanied by a mount error in
    recovery mode where you get unable to mount Data,
    Cache, System, SD card… etc partition errors while
    attempting to wipe the Android phone or flash a ROM.

    Resolving this issue is easy once you are able to diagnose
    and identify the culprit.

    Could my phone be infected with a Virus or Malware?
    Quite possible. In many cases like this where a virus or
    malware is involved, you’ll usually end up with a corrupted
    storage partition, and guess what! A corrupted storage
    partition is the most common cause of the Application not
    installed error.
    The possible virus or malware attack is
    however not serious enough for you to
    format / wipe your
    Android phone so don’t delete all your precious files out of
    a panic attack.

    While installing an app on my Android phone, I get an
    error saying I am not allowed to install applications from
    unknown sources, what does this mean?
    For security reasons, your Android phone is set to only
    install applications from the trusted Google Playstore.

    can however disable this setting by going to Settings >
    Security > Ticking “Unknown sources”.
    What could cause / result in the “Application not installed”

    The most common causes of this error are:

    Corrupted phone storage / SD card: This is the most
    common cause of this error. If the location where an
    application is supposed to be installed has been corrupted,
    it only means there’ll be no place to install the app
    doesn’t it?

    Insufficient storage space: There might not be sufficient
    storage space to accommodate the new app
    Corrupted app (apk file): The apk file (Android apps
    are in .apk format just like Blackberry’s .jad or
    Windows’s .exe) might be corrupted or incompletely
    downloaded / copied.

    Permission error: The Android phone might be going
    through a permission crisis.

    Temporary OS glitch: The Android OS might have
    encountered a minor error.

    Apk signed certificate clash: Trying to install another
    version of an app (with a different signed certificate) on
    the same phone will result in this error.

    Installing an unsigned apk: Trying to install an unsigned
    apk could result in this error.
    Wrong app installation location: Some apps will only be
    successfully installed on phone memory while others can
    be installed on both phone memory and SD card.
    Trying to install the former on SD card could result in
    this error.

    Installing on a mounted SD card: Trying to install an
    app on a mounted SD card will result in this error
    because the SD card is inaccessible

    Unacceptable apk name: Renaming some apk files prior
    to installation has been known to result in this error

    How do I fix the Application not installed error on an
    Android phone?

    Reboot the phone: Rebooting the Android phone could
    help clear OS errors that might have occurred.
    Check the SD card for errors and fix if required

    Format the SD card: In extreme cases, move the
    contents on the memory card to a different location then
    format it.

    Wipe the phone: In extreme cases, wiping the phone
    could resolve this issue. You could either do a factory
    reset under Settings or data / factory reset in recovery
    Ensure to uninstall unneeded apps to create space.
    Uninstall any apps you don’t need.

    Double-check the apk file: Check to be sure the apk file
    was properly copied / downloaded and is the correct

    Reset permissions: Try resetting app permissions
    (Settings > Apps > All > Menu key > Reset application
    permissions )
    Uninstall any previous versions on the same app
    currently installed on the Android phone.

    Change Installation location: You could toggle application
    install location between phone memory, SD card and
    Ensure that the SD card in not mounted / connected
    to a PC
    Avoid installing unsigned apks or changing apk file names
    prior to installation.
