People made mistakes, company made mistakes, everybody made mistakes. It is normal. Although it is acceptable but sometimes mistake can put someone into big shame like what has happened to Sony recently.
It is obvious that the Xperia line of smartphones tends to look a little similar – there hasn’t been a major change to the blocky slate-style industrial design for several generations. It’s understandable, then, that you might confuse the Xperia Z5 Compact for the Xperia Z5 Premium.
Aside from the screen size, the exterior design differences are negligible but sometimes it is not so negligible for someone like a Sony employee presenting the phone.
Let’s see it in the video below:
Well, you can see the difference right away between the phone on the table in the live video and the render that pops up at about the 25-second mark. If the smaller and relatively thicker Z5 Compact is not enough, the Xperia Z5 and Z5 Premium have their rear camera flash module below the lens while the Z5 Compact places it on the right. The Z5 Premium also has a glossy glass back while the Z5 Compact uses colored metal.
Here are some side-by-side press shots of the Z5 Compact (left) and the Z5 Premium (right).
