iPhone 4 touch problem
Just recently, I noticed that that the right hand side of my Iphone 4 periodically malfunctions. On 4 to 5 occasions in an average daily use of my phone, the touch sensitivity of the right hand side becomes distorted. The effect is felt by any application that is opened during such occasions. For instance, if I were to use the dial pad during the malfunctioning period, the "3, 6, 9, #, delete and voicemail buttons become distorted. I might want to press 3 bt any of the numbers or function on that column will just press itself. After that period everything goes back to normal. After another long period of use still within a day, it reoccures. Please what could be the problem and what can I do about it. I have exceeded my warranty period.
