This is a very big problem for apple’s phone allover market has very low. The customer has not satisfied to use this phone.
Firstly the major problem is technically fault in the mobile like network problem is the major fault for the user and the user hold the call many times they cannot talk to each other.
The user already have seen the signal strength is drop down and they are promising the software will be update and easy for the read out. At the beginning when the people bought an iPhone 4 they got trouble by call drop and poor receiving.
Those customers who have not satisfied they want to return the iphone4 within30 days of purchasing and finally most of the users they make a queue for returning the phone with the problem of make calls.
