I rooted my phone and everything went so nicely and I efficiently and carefully "boosted-up" my phone. But unluckily, I somehow uninstalled such system app which lead me into a weird problem. The problem is that the screen never accepts my input after it gets locked up after the time I set in settings. Absolutely no touch or hardware problem, the problem is on the software-end. Can anybody tell me which application the Android 2.3 triggers when the screen is touched to unlock after it's been locked automatically...? Kindly help...! Thanks.
