Oukitel K4000 weak point: back plastic assy.

  A week ago, I dropped K4000 in Marshal shop in Las Vegas. My K4000 protect shell has broken but K4000 itself was looks OK. But after came back to South Korea, I found cracks in inner plastic case while changing SIM. So I teardown cover.

 Middle metal frame was looks well made in price, but plastic cover was not. Each screw hole was damaged or going broken. It was marked ABS+PC, but seems just ABS or cheap plastic.

 Maybe dropping impact harmed each screw assemble parts, but I don't understand they shown nail down with K4000 screen, or dropping test for about 2 meters.
 Actually K4000 is too weak in back side. I know it could be replaced, but there's no serive office in South Korea. Maybe I could buy new one again in charge price of service.
 But it was really disappointed issue for expecting really powerful strong durability as their slogan.
