How to fix “App not installed” Error – Android

While installing some apps you might get the below error:

App not installed error android

This happens for 2 reasons:

1. If an older version of the app is already installed.

2. If Google Play Security Scan is enabled and it doesn’t find the app safe enough to be installed.

Google Play Security Scan normally doesn’t allow apps downloaded outside of Google Play to be installed and throw the above error “App not installed.” while trying to install it.


To fix the problem just uninstall Google Play Security Scan.

Go to Settings -> Security -> Google -> And uncheck “Google Security Scan.

In some devices, it will be under

Settings -> Google -> Security -> Google Play Protect -> Gear icon on top left

would you have any plan for update for this issue?

and this app’s name was ‘Audio Rec’, have you any plan to change this app?

and also, When using this app, is there a way not to disturb other apps such as other recordings, video recordings, and VOIP?

Hi Srihari, The Call Recorder is working fine on one of the device but suddently stopped pulling Audio Files from another 2nd device. It was pulling on the new device earlier but has suddenly stopped i guess after that phone was done with a OS update. Target phone is Samsung S8 running Pie with latest update done 2 days ago. Pl advice a solution for the same. Should i uninstall and reinstall the app there?


Hello Srihari,
Thanks for this wonderful app. It helped in saving my marriage by taking precautions. Stay blessed.
Could you keep the name as Record Audio or anything not beginning with the letter A. It shows up in the top of the list of Apps and my spouse commented that the icon looks scary.
