I immediately got Sony Mobile's large SIM-free smartphone "Xperia XA1 Ultra" released in late May in Taiwan, so I will review it.
The basic specs are differentiated from the "XZ" series with sufficiently high image quality and high sound quality functions
Xperia XA1 Ultra is the successor model to "Xperia XA Ultra", and although it has a 6-inch large screen The main feature is that the bezels on both sides are narrow and the borderless design that is easy to hold is adopted. The bundled items are flat earphones, a USB Type-C cable, and an AC adapter that supports quick charging.
The model I bought this time is "Xperia XA1 Ultra G3326". Equipped with Android 7.0, the display size is 6-inch full HD resolution (1080 x 1920 dots), the SoC is Helio P20 made by MediaTek, the memory is 4GB, and the storage is 64GB.
The rear camera is a 23-megapixel camera equipped with the same sensor as the "Xperia XZ", and the front camera is a 16-megapixel camera with a flashlight. Supports DSDS with nano SIM x 2 slots. Around the network, Bluetooth 4.2, Wi-Fi (IEEE802.11a/b/g/n/ac), NFC, FDD-LTE (B1/3/5/7/8/28), TDD-LTE (B38-41 ) does not have a fingerprint sensor.
Functions such as "Triluminous Display for mobile" and "X-Reality for mobile" that are installed for high-end users to improve image quality, and "DSEE HX" that upgrades compressed music to high-resolution audio equivalent Not installed.
"ClearAudio+", sound effects, dynamic normalizer and aptX are available. Even though it's a middle-range model, I would have liked to see a little more technology for higher image quality.
This model is also equipped with "Qnova Adaptive Charging" that extends the life of the battery. We won't know how effective it will be until two years from now, so I won't comment here. MediaTek's proprietary high-speed charging technology "Pump Express" can also be used with this model.
There are almost no bezels on both sides, but it is a little difficult to operate
The exterior is made of resin-like material, and the back is not made of aluminum, so it does not have a luxurious finish. .
The design of the first model was rounded, but the Xperia XA1 Ultra is less rounded. The reduced roundness does not make it difficult to hold, and thanks to the narrow bezels on both sides for a 6-inch smartphone, it can be held with one hand.
However, it is difficult to operate with only one hand. There's also a one-handed mode, but I don't use it because it takes away from the big screen advantage.
Can be operated with one hand
Thin bezels aren't necessarily justice, and when I held the main unit, the base of my thumb hit the display and I often accidentally tapped it. I would like to have this adjusted properly.
No matter how narrow the bezel is, it's still a large screen, and it's equipped with a ring-shaped accessory that can be used as a stand and to prevent it from falling off with just one finger.
The glass surface has a fairly gentle 2.5D process, and although it feels good to the touch, it is difficult to find a glass film that can protect the entire surface, or it is a half-finished type that cannot cover the entire surface. , Not limited to Xperia, recently smartphones have such troubles. The Xperia XA1 Ultra is no exception.
Compatible with DSDS (Dual SIM Dual Standby), which can communicate two SIMs at the same time, which is often found in SIM-free smartphones in Japan. The Xperia XA1 Ultra has an unusual specification, enabling the combination of DSDS + micro SD thanks to the micro SD being prepared separately from the SIM slot.
The interface has also changed, with changes to USB Type-C. USB Type-C is very convenient because it can be inserted regardless of the front or back. With recent products adopting USB Type-C, this change can be said to be natural.
The earphone jack is placed on the top, and there is no strap hole or fingerprint authentication sensor. Also, since it is not waterproof and dustproof, it is wise to avoid watching videos in the bath or using it around water.
