Zoom bug still?

Have had phone since February 1, 2018. Updated, reset, force boot, and still zooms in and out, selects items on the page on its own, opens windows on its own, the only fix is to manual shut screen off then unlock screen. Repeats 60 seconds later. Eventually it dies down and works fine for an hour then starts all over for hours! I have no handicap settings on. I’m an IT guy so I know how to trouble shoot. It’s a quality / hardware issue but if I turn my phone in, I get a used refurbished phone which is a scam. $1,000 and I get a used product that has depreciated tremendously. Are we waiting for a class action before the phones are recalled? Everyone seems to have this issue. The update did not correct it.
