Purchased this phone in the month of April 2012.
Did go for motherboard replacement thrice but I am still satisfied with my cell. It continues to offer some amazing pictures, the camera is one of the best around (found it convincingly better than my cousins iPhone 4S).
It is a fast phone and does hang up sometimes but overall it keeps my work going on.
The only problem with the cell is that it gets heated easily and dissipates power, leading to low ratings on battery life. Cant use it a lot on a daily basis, Samsung mobiles takes the prize away in this category.
