Ive recently updated to the android version 47.1.A.12.119. But im not sure when i wasnt able to do this.
I cant seem to find and enable the "Install apps from unknown sources"
I know its meant to be in System -> Lockscreen and Security, like many other Android phones. But the option just isnt there.
Had a look thgough the developer options too but nothing about unknown sources.
Has this feature been removed? Or put somewhere else?

This setting is embedded into every app's permissions. For example: if you download an app through Chrome app, you must grant Chrome the permission to install APKs from Settings -> Apps & notifications -> App info -> *app name* -> Advanced -> Install unknown apps

As @Quester wrote, the setting is embedded into each application in Android 8, so there is not a general switch to allow this from every application and instead you can only allow it only from a specific application, for example Chrome. You can also see a list of applications in your device from where you can install APK files, in case you want to have a better overview over this.
To find this list, go to Settings > Apps & notifications > Tap Advanced > Special app access > Install unknown apps. Here you can enable or disable the function as well!
I hope that helps!

Thanks for the replies, i have located it now thanks to both your information.
Didnt realise it was swapped to a per app basis. Shows how long ago i needed it!

You're very welcome and it's not very often you have to use this feature thanks to the Google Play store having so many applications to choose from!
Have a great day!

I am using the Sony Xperia XZ Premium. I have to download an app for the company I am working for to use on my phone. The app on playstore does not yet work correctly so they sent me links to download the apk files. I have downloaded the apk file but my phone just say "Can`t open file". I have tried the solution and turned the setting on to allow apps from Chrome as I downloaded the apk from chrome but still does not want to open.

I have had to try and install an app I had from Amazon on my old Z5...
I downloaded the Amazon app store, chrome needed permission to install which I gave it..
going into the Amazon App store it offers my previously bought apps but on clicking install comes up with a wizzard to turn on "from unknown sources" which of course scrolling down the settings page it takes you to there isn't one.
for a laugh i scrolled down to "apps with usage access" and enabled Amazon Appstore for whatever that is meant to do... and still Amazon app store stops with the "Enable Apps & Games" wizzard saying I need to turn on Unknown sources.
I found a website saying how to do it under Oreo Settings/apps& notifications/special app access/install unknown apps and Amazon appstore is showing as "allowed" (as is Chrome)
but Appstore won't install anything still (i have tried rebooting the phone a couple of times too)
