Hisense
Hisense ships TVs on several systems (VIDAA on most of its own models, plus Google TV, Roku TV, and Fire TV variants), so menus and fixes vary by model. Wi-Fi dropouts, unresponsive remotes, and apps that stop loading are the usual complaints, and most clear up with a power cycle or a network reset.
