The Intex Cloud FX retails for about $35 in India, and its intent is to bring smartphones to people who traditionally can’t afford them. So, what do you have to sacrifice to bring a smartphone’s costs down that far? Well, it has a 3.5″ 480×320 display, a 1Ghz A5 CPU, 128MB of RAM, and 256 MB of storage. (Those a megabytes.) There’s no GPS, no notification LED, and not even 3G support. They say the build quality is as poor as you’d expect, and if you aren’t at a 90 degree angle with the screen, colors are distorted. But, again: it’s $35 — this is to be expected. How well does the phone work? Well, the UI works well enough, but multitasking is rough. Everything’s functional, but slow, sometimes taking several seconds to register touch input. The real killer, according to the article, is the on-screen keyboard, which is unbearable. The article concludes, “Sure, we’re spoiled, “rich” people compared to the target market, but it’s hard to believe that this is a “best attempt” at a cheap smartphone. … The problem is that Firefox OS just isn’t the right choice of operating system for this device—it’s trying to do way too much with the limited hardware. It isn’t configurable enough.” They say the phone doesn’t even make sense for a $35 budget.
