As far as I understand the support team, the specifications for the "same" models should be basically identical, and any differences should only be due to registration errors. For the white OPPO Find X5 model, it is noted that a case is included, which was also confirmed in a review. However, when viewing the black model, a reference is made to a black case under "often bought together with". So my question is: does the black model also come with a case and would the other one be additional (better), or would you have to order another one for this model?
