I've been using my Zenphone for 3 months... Now I can feel under my fingers and see in harsh direct light that the back of the phone is not perfectly flat.
This small bulge has the size and shape of a battery and is located in the same area.
But it's really slight
Can it be normal? Did I just not notice it before?
Are there any Zenfone 9 owners who can check their phones?
Perhaps I am oversensitive? Maybe this tiny bulge is just a back tap reading system?
