When talking about the GT-I8580, now or in the future, two thing are sure to occupy most of our attention. First, assuming that this indeed will be marketed as a smaller alternative to the S4 Active, we should begin with the fact that there's nothing mini about this phone. And second, unlike the new trend-setter, the Sony Xperia Z1 f, this device has been watered, nay, stripped down to its bare bones and left just enough to make do, but no more. To start off, it's got a 4.65-inch screen that runs a lowly 800x480 resolution, or 200ppi. Things are a bit better at the performance department – the phone is powered by a 1.2GHz dual-core Qualcomm Snapdragon 400 Plus with Adreno 305 graphics, and a gigabyte of RAM. The rear keeps a 5MP camera, and you'll be able to snap some pixelated selfies, thanks to the 0.3MP snapper at the front. Thanks to the GLBenchmark test that you can see below, we know that these internals transform into adequate performance, though the low resolution sure helps with that. The phone runs Android 4.2 and has received WCDMA certification, meaning that we could see this phone cross the Chinese border into Europe and other areas.
Of course, while this device is but a shade of its flagship twin, we pretty much take it for granted that it will be aimed at the entry level market, where specs like these are still the norm. Well, at least as far as the mainstream is concerned, anyway.
