Google has already announced its Nexus 5X, and the device is getting a good amount of attention from consumers given its good range of specs and features and its reasonable price tag of $379, but tech sites have called it Google's biggest letdown. Find out why.

Google's Nexus 5X has a 5.2-inch Full HD display and it has a very familiar design and build given its soft plastic material back. The Android Marshmallow-running smartphone was made in partnership with LG, and the partnership may have reaped a really good phone which comes with a fingerprint sensor on the back which can be used to turn on, wake and unlock the device via the Nexus Imprint software feature, as noted by Android Authority.

It comes with a Snapdragon 808 chip and 2GB of RAM, which does the job pretty efficiently given the functionality and the operating system of the device. The Nexus 5X comes with front speakers reminiscent of HTC devices' speakers.

The build of the Nexus 5X is very similar to the Nexus 5, but the back camera follows the camera package of the Nexus 6P which has a protruding bulge to compensate for the 13-megapixel primary shooter. The camera also comes with a variety in-app features including 4K video recording.

The Nexus 5X has a 2,700mAh battery which is already very good in providing sufficient juice to the relatively large smartphone. The handset retails for $379 in the U.S. for the base model, according to Android Police.

Despite its good qualities, several tech sites are warning interested consumers of the biggest letdown of the smartphone package one gets when buying a Nexus 5X.

Droid-Life noted that unlike the Nexus 6P, the Nexus 5X does not come with a USB Type-C to USB Standard-A plug cable, or the cable smartphone owners use in connecting their devices to a standard USB port of a desktop or laptop or a typical USB charging adapter.

Phandroid's Chris Chavez expressed his disappointment over the lack of such connecting cable and what it would mean to most users writing: "Well, that means you wont be able to use the included cable in your existing USB chargers, car charger, or even plug it into your computer. That is, unless you're sporting one of those fancy new MacBooks Apple recently released."

Also, this would mean additional expenses to consumers who want to have a USB Type-C to USB Standard-A plug cable. There are cables available on Amazon and most of them are priced at $10 and below.

Google also has a recommended cable on its Google Store and it is available for $13.
