Money is urgently needed, so I am selling the phone... But there are only two black spots on the two sides of the phone, I have been using it like this for almost 1 year and nothing happened... You will get a lot of comfort using the phone, the charging backup is also very good. It doesn't lag at all, you can run it very smoothly, both side cameras of the phone are very nice, no problem, you can come and see it in person
