Hi , I recently bought a limited edition last of us part2 dualshock 4 , the screws are orginal and the battery will keep up around 7,8 hours , but I got worried about some few things : when I take the screws out and tryin to open it up with my hands it wont open , it's so hard , and another thing is it's a little bit lighter than the orginal model that I had before 2016 , and keep that in mind this controller I bought is a new series , and when I press ps button to turn on the PS4 , the color is aqua , something like bright blue , but when I take picture of it , it's bright white , and yeah , I will be so thankful if you respond , thank you ,
