Great Quality Phone, with no Lag even when installing more than 25 apps at the same time and using it. I used the same phone for 5 years at a stretch and still the phone is working as a charm - but slow sometimes when playing games!
The major con of the product is that the battery can not be removed at all, and if there is some problem with the battery then you will have to bear extra cash of replacing the LCD Panel.
Cons:
Non-Removable Battery - and the phone can be opened from only front side, thus you will have to bear extra cash.
Camera Quality is super Bad!
I gave 4-star to the Product only because of its durability and performance!
