I bought the hisense sero 7 for my kids last Christmas & have since been researching different safety & filter options. The best thing I have found to do for us right now is to just use an app blocking app. My only issue I've found though is for their ebooks. In order for them to be able to read I have to unlock the nook app or the kindle app, but I don't really want that cause then they have free range of their stores. So my question is, is there a way I can put their books straight on their wall with a widget, that only allows them too see those books? Or even an app?
