LG informed about two new X models: X5 and X Skin. Well… they doen’t really offer anything except small size.
X5 is in best midranger:
System: Android 6.0 Marshmallow;
Screen: 5.5”, HD (1280×720), IPS;
CPU: quad core 1.3 GHz (probably MediaTek MT6735);
RAM: 2 GB;
Internal Storage: 16 GB + microSD;
Cameras: 13 MP rear and 5MP front;
Accumulator: 2800 mAh;
Other: Wi-Fi (802.11 b, g, n), Bluetooth 4.2, USB 2.0, NFC, Dual SIM;
Size: 151.6 x 76.9 x 7.2 mm;
Weight: 133 g.
Price: about $173.
In theory its major advantage is size but it’s only one this model have.
X Skin have weaker components but its price is higher due to smaller size and weight:
System: Android 6.0 Marshmallow;
Screen: 5”, HD (1280×720), IPS;
CPU: quad core 1.3 GHz (probably MediaTek MT6735);
RAM: 1.5 GB;
Internal Storage: 16 GB + microSD;
Cameras: 8 MP rear i 5MP front;
Accumulator: 2100 mAh;
Other: Wi-Fi (802.11 b, g, n), Bluetooth 4.2, USB 2.0, NFC, Dual SIM;
Size: 144,8 x 71,4 x 6,9 mm;
Weight: 122g.
Price: about $200.
So none of above models is veary interesting – yeah, they are small and light but that’s all. LG lost idea of X series and I have hope that they’ll find it fast. (On photo X Skin)
