I am using this excellent tmobile touch screen phone from almost one year and had never felt any problem till today morning. Today in the morning when I was operating my tmobile I felt that it is not working swiftly. It was really responding very slowly from its touch screen. I had also got qwerty keyboard and it is working very fine with it. I had also restored my tmobile touch screen phone but problem still exist. Anyone had experienced the same problem. What should I have to do for fix the problem?
