Flat sides are totally trendy right now so Sony is also moving in that direction now. Furthermore, Sony does not seem to have made things very difficult for itself, because in terms of appearance, this Xperia 10 IV is very similar to its predecessor; the Xperia 10 III.
The display measures 6 inches diagonally just as before and there are 3 different cameras on the back. The fingerprint scanner is still found on the side and dual speakers with a separate input for your headphones are still expected. What processor the Sony Xperia 10 IV uses, how much memory and how large the battery is we do not know. The source does make an educated guess but we don't find it very reliable as of yet.
Unknown source, yet trusted origin
So why are we publishing the images anyway? Because the renders come from @Onleaks, who usually shows reliable renders of unannounced phones. This Steve Hemmerstoffer sells his images to the highest bidder and that was this time Zoutons.ae.
When Sony will officially announce the Xperia 10 IV we unfortunately do not know yet. We won't be surprised if that happens soon.
