Quick story. I purchased a Sony tv with android OS. In the store, the OS did everything I wanted.

When set the system up at home, it worked just like in the store.

Then five days later, an OS update forced ads onto the front page. The entire home page was changed from what I had purchased.

Fortunately, I could reset the device back to the previous OS version and not let it anywhere near a wi fi.

What I purchased and what I was having in my possession became antithetical to what I wanted with a software update.
