Have you had a closer look at that 'landfill' recently?
I'm not sure that 'Android Landfill' is an entirely fair term these days.
I picked up an Alcatel Android phone yesterday from EE for £19.99 PAYG. The brand is being used by the Chinese company TCS.
This has a dual-core 1GHz Mediatek processor, 512M RAM, 480 X 320 3.5 inch screen, removable battery and micro sd card slot. It runs Android 4.2.
Sure, the camera is fairly crappy and the front screen is plastic, not glass. However it came with almost no bloatware, runs surprisingly fast, and benchmarked up with Antutu at around 10,000 compared to my Note 3 at around 30,000. The only really weak point was 3D graphics, perhaps not surprisingly, but most of the detailed benchmark figures such as integer and floating point performance were around half those of the Note 3.
It also has Bluetooth and GPS, by the way. And an FM radio. It came with a charger and USB cable plus a set of earbuds.
A device like this in a developing nation would be a truly empowering piece of kit. As it is, I am amazed you can buy something like this for not a lot more than my daily commute costs me, or, looking at it another way, I could pick up 30 of these, and equip a whole class of students, for the cost of one iPhone 6.
And this is just the beginning of 2015. What will the Chinese be able to produce for this price point in a year or two?. We may chuckle, those of us who can afford to drop hundreds of quid on the latest top-of-the-range smartphone, but this little device acquitted itself incredibly well for the price, and I think it's entirely unfair to call it 'landfill'. For goodness sake, even a Raspberry Pi costs more!.
