@Flood and Flood's wife Interesting. In fact, I downloaded from Huawei, and it seems OK with my Samsung! I think I was misled by this documentation page in the Knowledge Base: Kaspersky Internet Security for Android which to me implied that downloading from the Huawei AppGallery was the only way to install Internet Security on the Android. [A few days ago, before I started this thread, I had tried downloading from Google Play Store, but I abandoned that approach because I could find no way to insert my existing Activation Code without payment. At least with the Huawei approach, I could enter the Activation Code without difficulty -- everything synced up nicely and works OK …... so far. [But from your last paragraph above it seems I didn’t go far enough, so I will now remove the Huawei version of Kaspersky Internet Security from my phone and start again by downloading from Google Play Store]. Thanks again for your help. Ian
