The price and full specs of the Sony Xperia XZ3 has been published by a British e-commerce store and the page even allows you to pre-order the phone.
However, the listing for the phone looks slightly off as the specs listed by the website does not equate to the specs that were mentioned in the rumours and leaks. A listing on GFXBench stats that the phone will come with a QHD+ Screen with resolutions of 1440 x 2880 and a 5.9-inch screen. The British e-commerce site, on the other hand, listed the phone as a 5.7-inch 1080 x 2160 resolution screen which is the specs on the XZ2 phone. In addition to that, they listed the cameras as a 19MP+12MP sensors which might be true as a leak has mentioned that the phone will come with the same cameras on the Xperia XZ2 Premium and a larger 3,240mAh battery.
The price stated on the website for the phone is 849 Euros (RM4005.12) which is a huge increase from the XZ2 when it released. We know that the specs listed on the site have to be taken with a grain of salt, but could the price of the phone be accurate, as we have known Sony does price their phone the same as other major flagship phones. We will only know when they unveil the phone during IFA 2018 which is happening on September 2018.
