Install the app on Android in a couple of minutes

The 100juz app is not yet published on Google Play. So on Android it installs from a file — called an APK. Nothing complicated: download → allow → open.

A safe official file. Download the app only from this page — this is the original 100juz version from Marine Health.

If something goes wrong

What can get in the way — and what to do

These are common situations on Android. Each one is fixed in a couple of taps.

Android blocks installs from unknown sources

This is your phone’s protection. Allow installs from this source — the phone itself will offer a button with the setting. How to do it is in the section below.

The browser won’t open the file right after downloading

Open the “Downloads” folder on your phone, or tap the file in the browser’s download list — and launch it from there.

The system says “Installation blocked”

You need to give permission to the app you’re opening the file from (browser or file manager). Tap “Settings” in that window and turn the permission on.

The system says “App not installed”

Download the file again and tap “Install” once more. If an older version is already installed, remove it first, then install the new one.

Not enough storage on the device

Delete unneeded photos, videos or old apps to free up some space — and try the installation again.

An old Android version may not be supported

The app needs Android 8.0 or newer. You can check your phone’s version in “Settings → About phone”.

Downloaded the file but can’t find it

Open the “Files” or “My Files” app → the “Downloads” folder. The file is named 100juz and ends with .apk.

One permission

What you need to allow on Android

To install the app from a file, your phone needs one permission. It’s safe and done only once.

Allow installs from this source
When the phone asks — tap “Allow” or “Settings” and turn on the switch. That’s enough.
Where this is usually enabled
The permission is asked for the app you opened the file from — most often the browser or the file manager. Sometimes — in the “Security” section of your phone settings.
You can turn it off after installing
If you want, turn this permission back off in the same place. It won’t affect how the app works.
Names may differ

On different phones the items are named slightly differently, but the meaning is the same — “allow installs from this source”. Look for similar words in your phone’s settings.
