I am going to write a review about Samsung Z2. It is a GSM/HSPA/LTE band which provides you the 4G speed of the level. It is a 4 inches TFT display which is 400 x 800 pixels. It is Quad-Core 1.5 Ghz Cortex A7. It has 1 GB RAM & 8 ROM which is sufficient for me to use it. This phone’s camera is 5 MP with LED flash. It has a removable battery of Li-ion 1500 mAh. It can standby by 30 hours. Its price is 4, 500/- I have been using this phone for 2 years an it is awesome to me. Thank You.
