Hi, 4-5 days ago i've updated my HTC wildfire S system software by going to settings > about phone > software update. After that my android version also updated to 2.2 to 2.3.5. ok now the problem is this sometime my phone's backlight turned on automatically and doesn't off. while in this after 15 sec(the screen timed out) backlight is going to dim and off suddenly(within a less then sec) its on and its happened continuously. & then when i restart my phone then its back to normal but after few hours or few days its going to happen again. so what kind of problem i have and its happening by the software upadate or may be by other apps which i have installed after updation. Plz help me Thanx in adv. all answer will be appreciated.
