"Front Glass Replacement for Galaxy S6 Edge+ Plus?"에 답변I don't know how you have searched for replacement screen. My first suggestion for you is to replace the screen at Samsung store. It might cost a lot, but reliable. You can also just find a common repair store, which should be cheaper. Or, you can buy a replacement screen online and install it yourself. Alibaba should have the cheapest screen. But, sharpen your eyes.
