I am one of the numerous persons who have issues with a completely white screen showing up on my iPhone 3gs. The symptoms are as follows:
Whenever the iPhone's screen turns on, the screen is completely white for a varying duration. Sometimes it's just for a second, sometimes it's 10 seconds, often somewhere in between. It can happen when I turn on my iPhone, when I "wake it up" from standby, when the alarm clock rings or when there's an incoming call.
During this period, the iPhone remains completely responsive. For example, I can anticipate the position of the unlick slider pretty well and unlock the device after waking it up from standby while the screen is still white.
The issue happens far more likely when there are many apps in running simultaneously. The less apps are running, the less often the white screen will appear and the shorter is the time it will remain if it appears.
Is there anybody else with these issues and has anybody found a solution to this problem?
