6/128 mobile's speaker was dirty, opened it to clean. The technician messed it up. Pressed and cracked a black spot while putting it back. Slightly visible at the back, almost unnoticeable. And a little at the corner. Noticed it when I came home. But touch and everything else is fine. Poly glass always used
Camera is also beautiful.
The problem is nothing much. If you want to buy, come and see.
