Hi, My Samsung Galaxy Tab S 10.5 suddenly incurred a wifi problem and is not connecting to a network anymore. I tried factory reset, but doesn't help. And I lost my apps of course. I thought I will use my beloved Nokia Here Maps app by installation via apk file. I managed to download and install it, but as soon as I try to open, it asks for a wi-fi connection. And because I have none, it closes. I know this app can work offline, because I used to use it like that, but perhaps it needs a wi-fi network to begin with. What could be a solution to bypass this, so that I can use my tablet as a GPS at least. Thanks.
