Can't install or update apps

Question

Whenever I try to install or update an app, it downloads to 100% and then just sits there. It won't proceed naturally from a completed download to app installation.

Sometimes, if I leave it alone for awhile (several hours - using the phone, but not bothering the installation) it'll suddenly finish the install. However, this is undesirable and unreliable.

I've tried all of the following several times alone or in conjunction with one another, and at least once in the following order:

• Stop all pending updates/installations
• Clear Google Play Store data
• Disable Google Play Store
• Force Stop Google Play Store
• Clear Google Play Store cache
• Reboot the phone
• Enable Google Play Store
• Clear Google Play Store data (again)
• Attempt only one installation

None of this fixes the problem. The single installation still downloads to 100% and then just sits there. It doesn't matter which app or update I'm trying.

I'd much rather avoid resetting the phone if possible. Is there something else that I can do to fix this?

Platform:

Samsung Galaxy S8+
Android 7.0
Google Play Store 7.8.36.P-all

Answer 1

It Usually happens during lack of space.If you have recovery in your phone clear the cache .I faced the problem in my own phone too.But it got solved after this.

Go to the Home screen menu and touch on Settings. Browse for the applications Manager. Touch on it to run it. Once it opens, change the tab to ‘All’ and then browse for the app “Google Play Store”. Press once on it to display its app information. Here, you will get the option “clear data”. Touch on that entry then restart Google Play Store.

If this doesn’t solve your problem, proceed as above but touch on “uninstall updates.” Hope this works for you:) I needed to restart my phone for this procedure to work.
