I came across this issue multiple times and I hope it's not too hard for anyone to make a toggle into the settings Hi Timmy93, I am a bit confused: the functionality of taking snapshots of private tabs is currently missing. So what are you asking to be removed? This feature has been requested to be added as a flag but was marked as "Wont Fix" by the chromium team.

I believe this feature was blocked to stop third party malicious apps from capturing private browsing activity without user knowledge.

Don't think we should enable it. Several reports are there on Chromium bug tracker that users have been able to use a workaround to take screenshots on Chrome Incognito tabs which the chromium team has acknowledged that the Android team is aware and fixing it.

So ideally we would end up in a situation where Android would block any workaround as well.

I see the problem but it's really a pity that to test some web app we need to use a secondary browser or a browser that allow screenshot in private mode like FF. I really hope that you can reach a solution also if it is not as easy as a tick box in the setting menu.

Timmy93 Agree its a challenge but need to consider security aspect as well. You may want to give this a try for development purpose as suggested by the chromium staff. I don't think we should remove the ability to take screenshots in private tabs just because there might be a malicious screen-capture. Sensibly, we use this flag for Private Tabs. That said, some users would like to take screenshots of private tabs. We could, perhaps, offer the option to allow screenshots for the Private Browsing Session, clearing user-consent when the private tab closes requiring them to consent again for the next tab.

I don't think consent needs to be given each time the Private Browsing Session so long as it is explained in a consent notification at first use.

I ran into this today. Use case scenario: I was using a private tab to browse Comcast Xfinity internet service offers in my area. I didn't want to be shown offers based on me being an existing customer, I wanted to see new customer offers. Found the offers, tried to screenshot for proof, was prohibited from doing so, and found my way to this issue.Magisk is a systemless root and module host for Android devices.

Native Alpha lets you transform any website into a native fullscreen web app on Android July 18, Unleash the true performance of the Red Magic 5G with this custom kernel July 9, There can be many reasons to prevent screenshot-taking in an application, but keep in mind that it is bad protection for secure data or anything that user should not save, see or remember.

A simple example of a work around is to take a photo of the device with another one. Anyway, is it even possible? It's quite simple to efficiently prevent screenshot-taking in Android. There are two approaches you might take. The first one is to forbid screenshot taking in the whole application easier to implement and the second one is to handle the forbid and allow methods from JavaScript code this approach requires you to implement a bridge from Android to JavaScript code.

Note : This is a full file example RN 0. If your project already contains this file, you can copy its entire content and replace your-app-name with your application's real name. You can find this at the top in the MainApplication. Note : Change your-app-name to your application's real name. Also make sure to rename the "PreventScreenshotModule" fields in this code in case you chose a different name.

Feel free to change the Promises output messages as well. Also make sure to edit all the "CustomPreventScreenshotPackage" fields in this code in case you chose a different package name. Open the MainApplication. Note : Change the package's name if you picked a different name in both the import section and the actual code. Unfortunately, it's almost impossible to prevent screenshot-taking on iOS devices.

There is no simple or efficient solution. You can only get information AFTER taking a screenshot and display some information or pop-up to the user. Historical note : Famous application Snapchat had this feature in the past.

They used some kind of trick that relied on forcing users to constantly be touching the screen to open messages. This meant that if a user tried to take a screenshot, the system action that handles this would force them to stop touching the screen for a moment.

As a result, the message would close and the resulting screenshot would show a different screen. Still, this solution is far from perfect and may not always work. Moreover, iOS made implementing this workaround impossible a few releases ago. Current tricks and solutions : There are basically two ways to prevent users from taking screenshot.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

You might want to team up with Davon redet It's pretty obvious I think. We don't want anyone to demand proof by screenshot that you have the app installed or that you're low risk.

Why is it working on iOS then? It was not to prevent screenshots, only the intent was to prevent sideeffct of Android making screenshots internally to show the "open apps" user interface of left button click. I get the point. Then how about adding a short explanation to attempted screenshots and letting the user add an advertising image when tapping the share button on the top?

This way the app can be shared using applications that need an image e. Instagram Story. Might be a quicker work-around until it gets split up into two activities. Thanks for all the suggestions. As this seems to require further explanation, we'll leave the issue open until we documented that properly. You could also use scrcpy.

The screenshot-block as it is implemented now makes absolutely no sense. See also If the app is not allowed to show up in the recent apps screen you have to also disable screenshots. I doubt that any app has the right to disable a feature of my phone. That would have to be court tested. A simple workaround to make quick screenshots without using the overloaded Google Assistant is to use "Screen Master":.

Should the community open an issue to show that they would like PR or similar be implemented? Right now, this issue here just asks for clarification, not for a change to screenshot taking capabilities. I want to keep a low profile for now and not reopen closed issues while the maintainers consider me to be hostile.Recently, I was scrolling an onion site on Tor Browser and I had to send my friend the screenshot of it.

Even if I screen record, things turn out to be black. Now, this got on to my nerve and I had to find a way. One easy way is to just take a snap from another phone and send it. But, I found an interesting way to do it via Google Assistant. So, here is how to take Screenshots of restricted Apps. This could be the easiest way to take a screenshot and it seems to work on most of the apps. It worked on Tor, Incognito mode on browsers and even banking apps. All you have to do is enable certain settings in Google Assistant.

We need to enable screen context in the Google Assistant settings. Now on the Explore page, tap on the profile icon at the top-right corner. From the extended drop-down menu, tap on Settings. On the Settings page, swipe right to go to the Assistant tab. At the bottom of the tab, you will see devices connected to the Google Assistant.

For this instance, we are considering our smartphone, so tap on Phone. But before you do it, we need to understand what this option does.

This is not of any significance and you can tap on Share Screenshot on this page. Now, Google Assistant will take a screenshot and will give you pop up to share with different apps.

The easiest way to take a screenshot in restricted apps is via Google Assistant.

I would recommend disabling the screen analysis settings once you have taken the screenshot. This protects your screen data from being analyzed by Google Assistant. Alternatively, there are several other methods to do this but that involves rooting your device. If you already have a rooted device, you should try the ReEnable Screenshot Module. This module enables the screenshot permission for the apps and hence you can take screenshots. For any queries or issues, let me know in the comments below.

June 24, In Android land, it is possible to protect specific components ex: activities from being screenshotted. In this blogpost I'll demonstrate a few Frida hooking techniques and patterns along the way to achieve this goal. The techniques explained here should also work for SurfaceView s. Window" ; 5. In 4 we create a bridge to interface with the Window Android class. In 5 we create a bridgee to interface with the setFlags method. In this case, since there's only one method called setFlags in the Window class, it is not nessecary.

In 7 we hook the setFlags method with our own implementation. These are basic bitwise operations in one line. Resuming main thread! The above hook is used when spawning an app. This means that our hook can intercept the target function on time.

But what if the app is already running and we try to attach to the app? Well since the activity is already initialized, the target function will not be called and therefore our hook will not get triggered. How do we proceed further? With Frida, we can scan the heap for objects class instances with the Java.

Found instance of FlagSecureTestActivity: com. FlagSecureTestActivity 3cb com. PhoneWindow aedcd6f Error: android. The first Google search result brings us to this Stackoverflow thread which suggest to move the code responsible for UI changes on the UI thread by calling Activity. We need a custom implementation of the Runnable interface. Luckily we can create custom classes in Frida too using the Java.

Runnable" ; 6. DisableSecureRunnable", 8. Activity", Activity"], Whenever trying to hook on the Java layer, we need to encapsulate our hooking code in Java. We create a bridge to interface with the Runnable class 5.
