a7 lcd flickers back and forth to viewfinder

[Ronnie B]

...I have two a7's and two a7ii's. I fired up an a7 and the display  kept  flickering between the lcd panel and the viewfinder, very erratic and very strange ! Put in a fresh battery and still erratic...Grabbed another a7 and it did the same thing...no way... ..tried the a7ii's and they both flickered back and forth with random movement...all had fresh batteries...anyone have an idea of what the problem is...thanks !!!

...ok, with a little help from Sony, figured this out ! when this problem developed I was wearing a bright NEON green athletic shirt...when I moved the a7 towards my body it triggered the eye start automation way too soon, replaced the shirt and all is back to normal...UN-BELIEVABLE ...
