Hello, I'm a long time Roku user. After some coaxing from a friend I bought a Toshiba Fire TV on prime day(July 2019). In the shorts time I've had it I've had to reset to factory settings, and a lot of buffering. I never had as many problems with roku as I have with this TV. Someone please explain, or direct me to a site that could, to me is this android TV? What's side loading? My friend is no longer available after he walked me thru the factory reset. Do I need to treat it like android (cache cleaner, virus scan, ram boost etc..) if so, what's the best apps for it? Preferably free? I feel so lost with this TV. Everyday I debate on sending it back, but I got such a great deal on it and the money I would get back I wouldn't be able to buy a standard TV with. I'm feeling stuck, so any information would be greatly appreciated.
