You deserve a negative feedback. Im sorry but I don't appreciate your unit in the 1st place it is not used for about a month, the smoothness that you texted me before is around 99% smooth but its not true coz your unit had no screen protector, 95% smooth and with slight defect- the lcd had a small green mark although it's not obvious but still it's a "defect". If you want me to erase this feedback give me a beep or a favor coz Im not swapping my phone with that kind of value you offer me in exchange of my c7.
