I've bought this one second-hand from one guy on Facebook almost a year ago. Recently it has this very awful problem with the screen.
Whenever I'm reading something, the screen start to went dark and darker, showing a while line in the middle, and i need to push the refresh button but after that it will keep went dark again and again. I have a video showing what I mean to you guys
Sorry for my bad English.
I have tried to factory reset it, but it did nothing, seem like a screen problem to me. After a few months I left it there and not touching it, it may working for about 1 to 2 normally and then the problem started to kick in again !
Anyone expericence problem just like me ? Please show me how to fix this, much appreciate

Below is the video that show the error. I hope you guy can watch and show me how to fix this problem
