Swedish Android site, SweDroid, has published details of the Xperia XZ2 and XZ2 Compact which they say will be announced at the event, which takes place around 6:30pm AEDT on Monday 26th of February. The phone has all the chances to appear before the public at MWC 2018, that's just the word Compact has nothing to do with it - look at the thickness of its body.
Sony is expected to follow the recent trends in smartphone design which include a metal or glass slab, a full or near full-screen display with the highest resolution du jour and the latest, most powerful SoC. Some of the other specifications included are 5.7-inch OLED display, 3420mAh battery and IP68 certification. It will be featuring an internal storage of 64 GB. As far as hardware specs are concerned, it is likely that this device will have at its heart the Qualcomm Snapdragon 845 processor. This will be a bigger device, however. Thanks to slim bezels, the XZ2 Compact will be a similar size to previous-generation 4.6in Compact handsets, according to the website.
Interestingly, the report mentions that the Xperia XZ2 will use a vibration motor for playing music and audio, but it's unclear how it'll work in practice.
The Sony Xperia XZ2 Compact may bear a price tag of 5,990 SEK, a sum roughly around Rs. 47, 940. Be that as it may, the user who posted the pictures on the internet guarantees that the Xperia XZ2 Compact does not come with a 3.5mm audio jack.
