Samsung Galaxy S4 – Can not install APKs manually

And although I can eg an app from the Internet (legally!) If you just go to the screen where you click on the Install button do I not get any further. I just can not push install but only to cancel.
In the settings, of course, unknown sources are allowed but I just do not understand why I can not install APKs manually. Previously it worked. The Google Play Store and everything works perfectly.
Does any advice?
Thank you


Maybe you've downloaded an APK that is not intended for your device or your Android version? :?


But this can not be. Tried it once eg with the bwin App. Have you uninstalled (they have prior days manually rausgemacht) then I tried it again to install but I can not click on the Install button. And the app is 100% compatible with my S4


Do you have any safety / anti-virus apps on the device?

No, none at all.


Have you ever rebooted the phone? Had the same problem sometimes. After nen restart it went again.
Or you Please bang time to time File Explorer and open the apk was going there. May be that which is adjusted in the default action for apk's.

Does not work too. When I press the Explorer Install coming back where you can either cancel or press to install the window. Unfortunately, I still can not Install thereby press or is there another way?


You can not install apk's on the PC? Via AirDoid or so ...

And what brings me exactly?
I can not press the Install button yes at every app. So I think that this somehow is on the phone ?!


it's on every app I have probably read;-)

have you tried ml an installer?
e.g Android Wizard from the play store or go to the not?


So I downloaded the grade. But when I press install apk is yes again, the screen where the corrections etc Rauf stand and you can either press the Install button or cancel. And I still can not press Install a result.
