My phone fall near to the floor and has broken the glass of the back cover. I am thinking about any kind of way to repair it. Any advice? Thank you.

No, it really isn’t. Just use a heat gun and pry the sides open with any plastic cards or such. Before taking the whole back glass apart, disconnect the camera cable and you’ll be fine. You might want to use the old camera gasket and materials if the new glass back doesn’t come with it.
