The Sony Xperia Z4 flagship smartphone, released on the local market, which later entered the international market under the name Xperia Z3 +, caused a mixed public reaction because the changes compared to the previous flagship are minimal, and in addition to this, the new product suffers from overheating Qualcomm Snapdragon 810 processor. In some cases, the chip overheats even when the camera application starts. However, rumors appeared on the network that in September Sony plans to release a whole line of flagship devices, which will differ significantly from the current one. Sony Xperia Z5, Z5 Compact and Z5 Ultra are expected to be released. According to unconfirmed information, the Z5 will be equipped with a newer Qualcomm Snapdragon 820 processor, 4 GB of RAM and a fingerprint scanner. Most likely, Qualcomm Sense ID development will be used, which uses ultrasound for scanning and is able to work through almost any hard surface. The main camera is 21 MP Sony Exmor RS IMX230 CMOS with support for 4K and HDR. The screen will have a resolution of QHD (2560×1440), and the battery capacity will be 4500 mAh. So far, all this information is only at the level of rumors and causes quite justified skepticism.
