The pack is a classic for the latest products Umi, a square box of a generous size with treatment embossed silver; on the rear we find a label with the model and IMEI numbers.

Box contents: Smartphone, 1 Power Adapter with USB socket EU 5V 1A, 1 USB cable Type-C, 1 booklet indicating the specifications of the smartphone and the arrangement of the various buttons / functions. There aren’t any additional film protector (1 is applied) and there are no headphones.

- External dimensions of the smartphone in line with other 5.5 "; it measures 154 x 77.4 x 8.5 mm for just over 200g of weight.

- Construction of good quality, use of materials pleasant to the touch and the side frame in aluminum.

- On the left side we find keys, and the right side we find the volume rocker on the top and the power button slightly lower.

- On the upper side we find the audio jack and the infrared emitter; on the underside of the microphone, the speaker and port USB type-c.

- In the back at the top center are slightly protruding from the camera 8 megapixel f / 2 sony imx164 (13 megapixel interpolated) and dual LED flash (not dual tone), and slightly below the fingerprint sensor.

- In the front we find the earpiece at the top, the camera 5 megapixel f / 2.4 fixed focus but with face detection and light sensors / proximity.

- The soft touch buttons are not backlighted.

- Cover fairly thin but with good interlocking with the body; It is smooth and quite slippery, but does not retain fingerprints (at least the white version). The physical buttons are directly on the external metal frame.

- External glass with rounded edges 2.5D with pre-applied film from the house offering a good flow and has a minimum of oleophobic treatment; no other films in the package.

- Display brightness is good, good viewing angle; HD IPS LCD screen with colors and sharpness well played good for the category.

- Touch-sensitive and comes with multitouch 5 touches, writing rapidly and with Swype function that you type with two fingers (Google keyboard used)

- Two sim slots: Both Micro Sim 4G (with dynamic selection software).

- Presence MicroSD slot with a capacity of 32Gb (I tested Samsung 64Gb and is properly recorded).

- Removable battery (weight about 55g) from 3200mAh declared, to the test with amperemether, we found about 3100mAh; Geekbench test has been very positive with more than 12 hours of screen on time.

- Android 5.1 without any customization and launcher 3 (to be replaced immediately with something better like Nova, Apus, Cm Launcher).

- Open the app and switch between apps very quickly, stock browser with a few bumps as always (we recommend Chrome). Task manager by pressing and holding the center button and option to clear all apps.

- Excellent management 16Gb of internal ROM that are available in a partition to 11.7 GB for apps and data.

- Good management 2Gb ram by Android 5.1 .. more than 1.5 Gb ram free after loading some apps into memory at startup.

Connectivity:

WiFi b / g with no problem stable signal, good power and coverage (not tested it in wifi dual band).

BT 4 tested pairing with headsets and car, also easily transfer with other Bluetooth smartphones

OTG: not tested because of the lack of USB adapter Type-C -> Micro USB

GPS: understated, cold quick fix in about 30 seconds but poor precision and tendency to lose the fix; we hope for a software fix.

Camera:

- Main camera Sony 8Mpixel f / 2 (13Mpixel interpolated) that produces valid shots with daylight; good focus and flash of good power; interface camera classic mediatek poor options; when using the flash or light conditions unfavorable, the quality of the shots falls but not overly, interesting seal at high ISO that allows to bring home click the "acceptable" even 1200 ISO.

- Sufficient video performance, slightly slow the focus and during the displacement along the axis of rotation, is present shuttering; the highest resolution of video is only HD .

- Secondary camera for Selfie 5 megapixel without autofocus but with face recognition, quality of the shots enough for video calls to some emergency selfie with good light.
