What makes a good phone/ particularly an android

1. Proccessor speed
     The proccessor is just that, it proccesses information and tasks that are going on in your phone. The more Hz the proccessor is and the more core's it has, the better. 600mHz is just about as low as you can go, this means 600 million Hz, per second seems fast, but not really. 1 gHz, means 1 billion Hertz, this is really fast, but if you root you can make it go faster. 1.2 gHz dual core, this means 1.2 billion Hz and the cores put less strain on your phone and yout phone does not overheat as much.

2. Screen/ Display
    The screen size and display vary directly, the larger the screen, the crisper the image, tft captive is the bassic touch screen, not the pressure kind but the normal iphone kind. amoled, super amoled are high quality screens. There is also pixel dislpay, vga, qvga, qhd, hd. the more the dimension, 320x240, 480x320 and higher, the better the image, less pixelisation, better and sharper image.

3. Firmaware versioin
    The higher the version, 4.0.3, the better. so if you have a choice between an phone running foryo (2.2.x) or gingerbread (2.3.x), you should get gingerbread, tablets run honeycombe (3.x), the best android version is ice cream sandwich (4.0.x).
