As part of the Android operating system, there is a limitation impeding the deployment of software outside the Google Play Store.
If it’s your first time installing an App through notonstore.com, you will be greeted with the following message as you try to install:
“Install blocked. For security, your phone is set to block installation of applications not obtained from Play Store”
If you have a phone running Android Oreo or higher, you won’t see a setting that allows you to install software from sources unknown. Instead, Google views this as an app request, and you are asked to install an app that you have from NotOnStore any time you want to.
But, what should you do to proceed with the installation?
To allow app installs from NotOnStore, follow this steps:
- Navigate to Setting > Security.
- Check the option “Unknown sources“.
- Tap OK on the prompt message.
- Select “Trust“.
All of that, now you can try downloading the Program again. Notice that these settings will be permanently stored in your operating system, so you can install Android Apps from ALL sources, not just from NotOnStore.
