Hours before the official release, the official publicity pictures of Sony's fourth generation Xperia 1 mobile phone Xperia 1 Mark IV were exposed in advance. It is worth noting that in terms of appearance design, Sony's mobile Department continued to move forward according to its own style without making much adjustment.
Although the mobile phone industry generally pursues a higher proportion of the screen, either using punching or bangs, and even starting to use the front camera under the screen, Sony's Xperia doesn't care about these. The frames of the forehead and chin on the front of the fuselage are still very thick, although the side frames on the left and right sides are narrowed. Although the off-screen fingerprint is relatively mature, Sony still chooses to place the fingerprint sensor on the side.
In the context of accelerating the elimination of 3.5mm earphone port in the mobile phone industry, Sony Xperia series did not do so. Sony's positioning of these products as multimedia devices in the first place seems to rule out the sacrifices that many, if not most, competitors have made.
