Hello everyone, Here I am going to give my revuew to HTC U Ultra.There are heavier phones around you but this mobile main quality is its glossy, shimmery, curvy coloured glass back. You have a choice of Sapphire Blue and Brilliant Black in India. According to HTC, the colour is bonded to the glass and there are multiple layers, giving it depth and richness. It’s hard to believe that this isn’t metal. The only thing I don’t like is the huge camera bump on an already thick phone.The look is certainly distinct, but it has its downsides. The entire rear gets covered in fingerprints and smudges with even the slightest touch, and you’ll have to keep wiping this phone if you want to show it off. It’s also incredibly slippery - you soon learned to hold this phone very carefully, and you couldn’t even put it in our laps without it finding some way to slide off. HTC includes both a microfibre cloth and a clear plastic shell in the box. Both are indispensable, but the shell adds even more bulk to an already unwieldy phone and cheapens its look, defeating the entire purpose of the glass back.Holding the glass front and rear together is a metal frame that runs around the perimeter of the U Ultra. It’s a slightly different tone of blue, which adds yet another dimension to the striking look when you turn this phone around in your hands. The power and volume buttons are on the right, and there’s a hybrid dual-SIM tray on the top. On the bottom, you’ll find a USB Type-C port and a speaker grille. There is no 3.5mm audio.The dual-LED flash and laser autofocus window have the same design, as does the ridged power button and narrow fingerprint sensor. Not all of these are good things - the power button is difficult to locate and too shallow to be comfortable. It’s tricky to use the narrow fingerprint reader and capacitive buttons, which are all placed right at the phone’s bottom edge, making it difficult to reach them and still keep the phone balanced.HTC has tried to implement a secondary screen in exactly the same way that LG did it on its X Screen ( Review) and V20 ( Review) models. It sits right above the main screen but doesn’t extend all the way across so that there’s still room for a front camera. It can display two lines of text and status icons, and some app notifications can be shown here. You can double-tap the secondary screen to check the time and notifications when the phone is in standby, without lighting up the entire screen.This additional strip explains why this phone with its 5.7-inch screen.One thing that HTC is notably silent on is durability. There’s no mention of water, dust, or shock resistance.HTC hasn’t detailed the exact resolution of the secondary screen, but it looks like a seamless extension of the main display, which has 1440x2560 pixels. It’s extremely crisp, with punchy colours and great viewing angles. The whole front face is made of Corning Gorilla Glass 5. We wouldn’t expect anything less at this price level.The SoC is a Qualcomm Snapdragon 821, which has two 2.1GHz CPU cores and two 1.6GHz cores plus integrated Adreno 530 graphics. There’s 4GB of RAM and 64GB of storage, with microSD card support going up to a theoretical 2TB, but you do lose the ability to use a second SIM. You also get 100GB of Google Drive space free for two years. 4G and VoLTE are supported, as is Wi-Fi 802.11 ac, Bluetooth 4.2, NFC, GPS, and GLONASS. Sensors include a gyroscope, magnetometer, and the usual ambient light, motion and proximity sensors. The phone and bundled Type-C cable both support USB 3.0 transfer speeds.There are so much more good about this phone.All an all this is a good phone in this price.
