Amazon has a policy fir the fire 7 that, IMO, is abusive.
They take control of you device and put as much junk on it as they think you can manage. Truth is, it is hard for normal people to manage that much garbage.
My recombination. Never, ever buy a 'Fire' device from Amazon. The insult your intelligence by selling products that you can not control.
The best device I have is an old Apple iPad. It just works good and does not push junk onto my screen. She has the Fire,I have the iPad.
My wife and I use our devices mostly for personal education and not for playing games. No, we are not anti-games. But we prefer to make oue own choices.
However, they do offer this item:
