hello I’m back
I found a transparent square in the upper left corner of the screen.
It blocks the buttons of my browser and I can’t click the back button。
I also found when I use software keyboard input the letter，it will appear in the square.I can select and copy it even though I can’t see the letter.I upload the picture of it.
I think the square may be designed there,but I still hope to be able to remove it.After all, the back button is still very important.
