    Hello, I am unable to update apps that have been installed from anywhere other than play store. Play store apps are still updating fine, no problems there.
    When trying to update, the update will download fine. Then when the install screen pops up I get a a cancel and next button, which are half way up the screen with the bottom half just white. The cancel button works but next does nothing. Also, I'm sure this next button used to be install.
    Any ideas?

    Welcome to Android Central! Which phone? It might be a screen overlay issue. Do you have any apps that use screen overlay, like screen dimming apps?

    Thanks for your reply. I checked setting and took screen overlay off all apps. So that's not the issue .
    The phones a Sony xperia xz. Any other ideas?

    Any 3rd party security apps installed? Also, try wiping the cache partition -- these steps should work: https://support.t-mobile.com/docs/DOC-28294

    Strange. These are apk files you're trying to install, right?

    I'm not sure what to try next, but ultimately, you may want to try doing a software repair using Xperia Companion: How do I perform a software update or a software repair on my smartphone or tablet? – Sony Xperia™ XZ support (English). This will wipe your data, though.
