Hi Experts, I am new to the forum and need your expert guidance.. I am using Samsung Galaxy S with version 2.2 since past 3 months. Although I love the phone, am facing problems with respect to lag/reboot/force shutdown of applications.. I have installed a number of applications (about 55) which I dont know if is high or low as compared to others. The problem I am facing is that of phone hangs quite often. I have installed Elixir widget to monitor the CPU utilization. I have noticed that the CPU utilization often shoots up to 100% even when no applications(3rd party) are being used. Phone reboots quite often and force shutdown of application is a common thing. I want to understand what could be the problem and how I can fix this..Will factory resetting help? Will rooting help (dont know too much about it)? Any advice will be most appreciated..
