RE: What smartphone would you recommend me to buy?
For phones under $200, I think LG Optimus L90 would be the best deal. It costs around $180 and it's absolutely worth the price. The phone has a big screen: 4.7 inches and has qHd display which is pretty good. It has 1 GB of RAM and 8 GB of internal storage, which is more than enough for storing photos, movies and songs. It has a high quality camera with 8 megapixels. The battery is durable too. In my opinion, Optimus L90 is the best phone for the price.
I'd suggest you to go to 1sale, bestbuy and slick-deals if you wanna check other deals.
Also, Chinese Android cloned phones would be great too.
