hello guys, I explain my problem: I have 2 days my xiaomi mi4 to 3GB RAM and 16 hd. I found that the display is slightly raised in the top to bottom on the left by showing a glimmer of light in, and the other corners is perfectly flush with the aluminum profile. What should I do to you? it is normal that there is this small mistake? I bought the phone from grossoshop.net I thank you and I apologize for the mistake.
