Hisense E70 Pro is a ****!

I bought a Hisense E70 pro almost a year ago, and only recently realised that my 50MP camera is just a feature filler. When I close the camera and switch camera modes, I notice that all modes display image even as I close the 50MP camera. It doesn't really work. And I'm still paying it off😭💔 This is false advertising and a *******
