I was ready to crown the OnePlus X as one of the best budget smartphones of 2015. Compared to other $250 unlocked devices, it's more powerful than the Motorola Moto G , more beautiful than the Alcatel OneTouch Idol 3 and runs a more updated OS than the Huawei P8 Lite .

The inexpensive OnePlus X is fast; beautifully designed and has some nifty customizable features

The glossy handset is slippery and has limited compatibility with key LTE bands in the US

This phone is the best budget phone of the 2015. And in terms of looks no one can beat it ever. It has Glasses on the front and the back which is the Very Premium Build. Performance is top notch. Best in Class. No heating issues in normal usage. Battery life is average not so good but average.

phone is good feature wise but as customer we have to see, service centre. once mobile is damage than no one repair at service they just replace parts of mobile..

The device was sent with a modified O. S. image full of malware and pre installed software not found in the official image. I had to download the image from oneplus website and flash the device again. The device works correctly though.

In my point iof view, the One Plus One is a really good phone for the price it comes. Really smooth. Got two slots where you can either put 2 sim cards or you can put a sim card or a memory card. It is really light phone.

Camera; Speed; Display

Inbuilt storage should be increased

Thank you so much for the speedy delivery - the phone arrived safely at my front door in one piece. (well, several pieces but you know..). I found it very difficult to find the OnePlus X in black so I'm extra impressed.

OnePlus' X is actually a well-configured mid-range smartphone at a fair price. However, it is combined with a bitter aftertaste seeing that the former OnePlus One high-end smartphone is superior to the X model in all aspects but its 64 GB version only cost 30 Euros (~$32) more.

stylish design; fast SoC; expandable storage; decent speaker; good battery life

sleek surface; card tray stiff-running with card; no USB Type C; no NFC; sluggish micro-SD slot; no 64 bit SoC

Dear Vlad, I like Android phones, but I don't like carrying around enormous bricks of technology - what's the phone for me?

Handsome; minimalist design; Vanishingly small and light for a 5-inch phone; Oxygen OS is an attractive take on Android

Slippery to hold; No fingerprint reader or NFC; Mediocre camera; Lacks proper LTE support in United States

The OnePlus X offers Gucci looks at a Gap price. In addition to a sleek glass design, the affordable $249 unlocked phone also offers some clever features via its OxygenOS, which is based on an aging version of Android. You also get decent performance out a quad-core processor and expandable memory.

Beautiful design; Affordable price; MicroSD card slot

Short battery life; Mediocre cameras; Heavy for the size

There were no smartphones in the $250 price margin which have solid construction and snappy performance. The market is still filled with plasticy smartphones that lack aesthetics.

Stunning construction Light weight Regular updates Long battery life No UI skins to bloat the OS Inexpensive Beautiful AMOLED screen

Average camera sensor Low light performance is not that great Slight heating while heavy games are being played No NFC and 5GHz WiFi band No fingerprint scanner Invite system Almost non-existent customer support
