As it a phone it should be able to make calls and it does so with great finesse. The call quality on the phone and the overall signal reception has drastically improved from the previous models but it did face some issues of signal drop as now the stainless steel brush metal chassis had some issues, but the issues were addressed to soon enough by the company with a signal enhancer case that only covers the rim.
The display is a retina display which is full HD, 960 by 640 in resolution and a charm to look at. The screen gives crystal clear display, in fact so clear that the text almost seems like reading ink written notes. The front has a VGA camera that is fairly unnoticeable and can be used for taking self pictures with ease or using it for video chat via the new facetime software.
The rear camera is a new 5mp led flash supported one with a very sensitive sensor which takes photos that can be easily compared with 8mp cameras on its rivals. The battery life on the iphone 4 is a big improvement too, now the phone easily lasts a day if not a day and a half with heavy usage.
The phone also features a brand new 3-axis gyroscope sensor which measures movement in three planes and makes the whole gaming experience even more fun. The speakers have been also pumped up to give it a better and louder sound. Overall it's a very good phone and is recommended for practical day to day use.iPhone 4 karachi ,all kind of phones at Hafeez Center
