Certain apps give a black screen in remote control

Hello,

I write to you perhaps with a rather strange question/remark.
This is because I have a handicap (muscular disease) which makes me almost completely paralyzed and thus unable to use a touchscreen. So I actually use the free version of Teamviewer in order to be able to use; my smartphone from my laptop pc.

Recently there must have been an update because since yesterday the remote control started behaving strangely. Today however, I had to consent on my smartphone to new terms and conditions, and the connection was normalized. But now several apps stopped working properly in remote control, they are actually opened on my smartphone but on my laptop I just see a black screen. It is only with banking or payment apps that I get this, so I suppose it's some sort of security update that prevents the remote usage of this kind of apps. Is this indeed the case?

Whatever the cause, for me this is a problem as I really want to use these apps and I am not able to use a touchscreen and operate my smartphone directly. I know there is allways a small security risk, but for me it is perhaps more important that I'm able to use these apps.
So my question is if it is possible to circumvent this new blockage in a way and keep using all sorts of apps in remote control?

Extra information: I use a Windows laptop and a recent Android smartphone from Samsung. My version of Teamviewer is 15.0.8397.

Can anyone help me with this?

Re: Certain apps give a black screen in remote control

Hi @JelleM94 

Thank you for your post. 

Can you please check your Samsung Knox settings? Maybe they don't allow you to remotely control apps like your banking apps and such. We did not implement such security feature.

Please also download the latest version of the TeamViewer app from your Play Store and make sure to have the latest version 15.1.3937 installed on your PC. 

Hope this could help. Wish you a great day. 

All the best,
Natascha

Thank you for your answer.

It could indeed be some kind of security setting in the OS of Samsung/Android, but I can't seem to find a way to change those settings. Can anyone help me with that?

Anyway, I will certainly also try re-installing Teamviewer with the latest version on both my devices. You never know that it helps.

Re: Certain apps give a black screen in remote control

In the meantime, I have tried re-installing Teamviewer on both devices, but unfortunately it didn't solve the issue.

But when I re-installed the host-app, I got a poç-up that I had to activate Samsung Knox if I wanted to use the remote control function. I tried once not pressing on 'activate', but then I just completely couldn't connect. When I first started using Teamviewer I certainly didn't get such a pop-up, so I suppose it has indeed to do with Samsung Knox. I'm quite sure, because I now also tried connecting with my sister's smartphone (not a Samsung) and I didn't have any issue there to access apps.

So can anyone help me with how to change Samsung Knox settings or if necessary how to de-activate it?
