Mine's Motorala XT500 - Android OS 2.1, 480 x 320 pixels, 256MB of RAM and 512MB of ROM, after using one year, it is a bit slow to start , thinking of get a new iphone (waiting for iphone 5 ), alternative.
I got a Samsung TXT. I really have it because it's the only free phone (you see, my family is a cheapstake, and my old free phone was dying) that offered the traditional 12-button layout (1 2 3 4 5 6 7 8 9 * 0 #), whereas the others ONLY had a keyboard.
I've got HTC Sensation XL White, it looks fantastic however the display resolution is relatively low for such a large screen. I like it on the whole and don't think I will need a new phone in the next couple of years.
I own Samsung J5 Plus because it is best choice for me especially working with my dissertation writing service company and assisting students to provide them help remotely.
