Iphone 3g was my first smartphone after that there was a few more smartphones i've used through the years... but of all the phone i've narrowed down to 3 of my favourite... Iphone 4S, Samsung Galaxy Note 2 & Google Nexus 5.
I'll just comment a bit of why i like those models i've mentioned:
Iphone 4S: This is my favorite Iphone of all. It is reliable, nice to hold in my hand and very easy to use. It was rugged. I dropped it countless of time still its working well. It was fast and smooth during that period it was introduced.
Samsung Galaxy Note 2: Most favourite Samsung phone. It was powerful, it could run anything i want it to. Customization was very easy especially with a lot of support online. The huge screen made it very easy for me to watch all the videos comfortably. Easy for me to share something on screen.
Google Nexus 5: Software feels very light which makes it very fast. I like the how the soft casing feels in my hand. The screen is just nice. Big enough to watch the videos and pictures comfortably while small enough to maneuver with one hand. plus its very thin and light.
Future smartphone hoping to get:
One Plus One, from the reviews out there. It looks like my kind of phone with the nice screen size, full of features, Good camera, nice to hold in the hand :)
