When "Norton 360: Mobile Anti Virus" app is displayed to be installed by the app store
first the button "Auf weiteren Geräten installieren" is to be pressed.
If I press this button
there is a request to select the device, on which the app should be installed
Gerät auswählen
Keine für die App-Installation geeigneten Geräte vorhanden.
Because there is no entry for the Huawei handy ( only the ones I have already installed ), I can not start the download.
And so, it is not possible to access the INSTALLIEREN button !
I'm a little confused. Your title says no Google Play. Then you mention an app store. The Google Play App store is the only official method to download the Norton 360 app. Downloading from there does not ask anything about a device.
If Norton 360 does not appear in the app store app, it is not available in your geographic location. If is does show, but there is no button to install, it may not be compatible with your device.
