Hot on the heels of supposed details about the Sony Xperia 1 IV’s camera equipment comes more news about the forthcoming flagship phone. First up, it seems the Xperia 1 IV will sport an E5 LTPO display from Samsung, with the OLED panel coming as a slight upgrade over the screen of the Xperia 1 III. This tidbit comes via known leaker Caybule (via Reddit u/High_Low_Rig), and if it is accurate, it should allow the Mark 4 variant of the Xperia 1 to utilize variable refresh rate (VRR) technology.
An FCC listing might excite hopeful fans a little bite more. The FCC ID entry for the Sony device is PY7-83262V, and it has been noticed how similar the listed phone dimensions are to the Xperia 1 III. In the specific absorption rate (SAR) report, there is some description of the “phablet device”: 168.4 mm (length) x 70.9 mm (width) and 162 mm display diagonal. Those measurements are the equivalent to 6.63 in x 2.79 in with a 6.38-in display diagonal. These dimensions certainly point to a possible Sony Xperia 1 IV device.
Again, if accurate, this would also indicate a likely imminent release date for the Xperia 1 IV. For instance, the Google Pixel 6 series was spotted on the FCC in September 2021 and came out in October, which means it is possible the Sony Xperia 1 IV could see the light of day in May (although expect a long and drawn-out schedule if its anything like the Xperia 1 III launch). This ties in neatly with a prediction made back in January by the prominent Xperia leaker ZACKBUKS, who stated a May release date could be on the cards for the Xperia 1 Mark 4.
