the offer seemed attractive, a little too ..... after 10 minutes of testing I quickly realized that I had to make a product "big stuff". installation made of small module in my galaxy note 4 so slightly "DIY" (no French record) I set up the phone on the LED base that turns from blue to green and nothing happens, no change after several minutes of loading . I take off my shell I check the fit everything meets the illustration of the box, but still nothing works ..... and best of all the sview window of my samsung becomes inactive ..... . short you'll understand if you have money to waste ... go !!!
