"Unknown sources" missing on Oreo

Hi, since the Oreo update I can't find the "Unknown sources" to install APK's freely. I'ts not under "Lock Screen and Security", and I have enabled Chrome in "Applications/Special Access/Install other apps" and I'm trying to install apps from the "Downloads" section of chrome, but it dosn't work this way either.
I was trying to install the Pixel Launcher as seen from here: https://theunlockr.com/2018/03/13/make-samsung-galaxy-s9-look-like-stock-android/
But everytime I try it I get the "<!> Application not installed".
I don't know exactly what says in english, I'm using my phone in spanish.
Any ideas? Thanks!

If you go to Settings-Apps-3 Dots-Special Access-Install Unknown Apps.
They've moved it so only certain apps can install unknown apps

Please help how to fix this problem. This doesn't work, I tried installing Accuweather pro several times. I have the app saved to my Google Drive, I click on the app and I see something called 'Staging App' and then I get this alert ' There was a problem parsing the package'. I currently had an older version of Accuweather pro installed and working fine. I decided to remove the old version and then reinstall it and I received the same alert. FYI the old Accuweather app was installed before the Oreo update.

Have you tried downloading your APP file from Google Drive to your phone then opening the copy on your phone, that should install the .apk

Go to settings on the phone >> apps >> 3 vertical dots at the top right corner >> special access >> install unknown apps >> and there enable the permission from where you are trying to download it.

All thank you,
I found out that you now have to download the app to your phone. Google Drive does not allow you to download and manually install .

Dear sir/madam,
Following your answer, in specific this part, "They've moved it so only certain apps can install unknown apps", perhaps someone could help me out. I use the Firefox Focus browser and this app doesn't show up in the list of apps that are allowed to install unknown apps.
* Does this mean Firefox Focus can't install apps from unknown apps, since it's not on the list?
* And perhaps we can conclude from that it will never be allowed to do so?
* Or would this app not be on this list, because I've never tried installing anything using this browser?
I guess the real question would be, what populates this list?
I hope to hear from you, thanks in advance, all the best.

Form what I've seen, 1st time you try to install apk from an app it asks you if you want to allow it?

That's what I was thinking as well, funny thing is that 'Google Chrome' is in the list and I've never used that browser. Unless it's there, because it's from Google

I have followed the above suggestions and have allowed Chrome to install apps since that's the browser I'm using. The phone says I have downloaded the app but it is not giving me any option to install it? Where did the download go and how can I get it actually installed? This is an app for work.
Edit: Nevermind - I restarted the phone and tried again and it worked. thanks.

Why does android gives the "Problem in Parsing" Error? + CURE

The Parse Error in Android devices is one of the oldest and most common error faced by Android users. The error usually pops up when one tries to install an app on his Android phone. The message appears "Parse Error: There was a problem parsing the package". It turns out to be "the application cannot be installed on your phone due to an issue with the parsing.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Causes of the Parse error in Android.
Before we proceed to the fixes, let’s see what can cause this error. There are several known causes today. The parse error occurs while installing an Android app on your phone. But, the causes can be different.
Making changes to the app’s manifest file (for example, changing the Android OS version).
Damaged or partially downloaded apk file.
Not enough permission to download or install third-party apps from unknown sources.(very rare)
Your Android smartphone OS version or the hardware of your smartphone is not compatible with the app.
Your device security system is blocking a third-party app installation.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Method 1: Allow Apps Installation from Unknown Sources
For the security reasons, the Android smartphone bans you to install third-party apps and software from all sources apart from the Google Play Store. Installing third-party apps from unknown sources can harm your Android phone.
So, if you are trying to install an .apk file, you may face the "Parse Error: There was a problem parsing the package". To fix this and bypass the ban, you should allow app installation from the unknown sources. There is an option in your phone security settings.
1)Go to “Settings”;
2)Then “Privacy”;
3)Find “Unknown Sources” and check the corresponding box. If your are prompted to confirm, tap OK.
4)Go back to the folder where you have the .apk located. Tap on it and install the app.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Method 2: Enable USB Debugging
Enabling USB debugging isn’t really necessary for installing Android apps using the .apk file. Nevertheless some users report that enabling the USB debugging fixed this issue.
To enable USB debugging, you need to enable Developer Option in your Android phone. In doing so, follow next steps:
Go to “Settings”;
Find “About phone” option;
Scroll down to “Build Number”. Tap seven times on it. After 7th tapping you hopefully see a “You are now a developer” message on the screen;
Go back to “Settings”, scroll down to “Developer Options”;
Tap on USB debugging and enable it
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Method 3: Disable Antivirus
The parse error can also occur if your security application is blocking the installation. Most of the Antivirus try to block the installation of the applications that may look untrusted or suspicious. So, if you are trying to install an .apk file, the chance of getting the error is that your Antivirus app is blocking the .apk file and preventing the suspicious installation. Try to disable the Antivirus temporarily and install the .apk file. If your guess is right, you should be able to install the .apk file without receiving any parse error in Android.
///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Method 4: Damaged or Partially Downloaded .APK File
A damaged .apk file might also be cause of the phrase. Try to download a new apk and install it. See if this can fix the issue. Besides, make sure you download the complete file. In doing so, it is enough to compare the size of prompting and downloaded file. Sometimes, you may partially download a .apk file and face "Parse Error" while installing it.

Magisk.apk Install Error - "app not installed"

I just to had to do a fresh install from a Qualcomm dump to 9.0.4. I am running into an issue when attempting to install the Magisk.apk. It attempts to install the apk, however, it quickly errors out with, "app not installed". I have turned off Play Protect. I haven't been able to find the 'Unknown Sources" switch to allow it - thinking that could be it.
Any suggestions on how to fix this issue?
Thanks, in advance.

For future reference....I found the answer by enabling unknown sources in Settings > Apps > Special Access > install unknown apps

The error message you encountered, "Turn on Chrome OS Developer Mode to install apps from sources other than the Play Store," suggests that your UMIDIGI BISON Pro smartphone is running on Chrome OS, which is primarily used on Chromebooks. Chrome OS has a security feature that restricts the installation of applications from sources other than the Google Play Store by default.
To resolve this issue and install downloaded APK files on your UMIDIGI BISON Pro, you'll need to enable Developer Mode on your device. Here's a step-by-step guide on how to do it:
Go to the "Settings" app on your UMIDIGI BISON Pro smartphone.
Scroll down and tap on "About Phone" or "About Device."
Look for the "Build Number" or "Build Version" option and tap on it repeatedly (usually around seven times) until you see a message indicating that you have enabled Developer Mode.
Now, go back to the main settings menu, and you should see a new option called "Developer Options" or "Developer Settings."
Tap on "Developer Options" to enter the developer settings menu.
In the developer settings, locate the "Developer Mode" or "Enable Developer Mode" toggle switch and turn it on.
You may receive a warning message informing you about the potential risks of enabling Developer Mode. Read it carefully and proceed if you understand the implications.
Once Developer Mode is enabled, you should be able to install APK files from sources other than the Play Store.
