After the latest firmware update (KI4 if I read all the numbers and letters in my phone info correctly) on my unrooted S2 I've started experiencing some inconsistencies in how long it takes for the screen to turn off after a period of inactivity - and this applies both to the homescreens and lock screen. I have the timeout set at two minutes (I don't think it's possible to set one manually for the lock screen as well, is it? Though I've never timed lock screen timeout I've always estimated it to be around 30 seconds). While most of the time the screen will turn off after those two minutes of inactivity on homescreens/apps, occasionally it will do that initial half way fade mere seconds after I last touched the screen, and then turn off shortly after. This has always happened after phone calls (I assume that's intended behaviour?), but now it also seems to do it on occasion at random out on the homescreens. Meanwhile the lockscreen - if activated but the phone not unlocked - will usually time out after those usual estimated 30 seconds, but on occasion it will instead stay on for, without pulling out my stop watch, seems like around two minutes. So somewhat odd and unpredictable behaviour overall with regard to screen timeout. I use GoLauncher and WidgetLocker, but until the latest firmware update I don't recall ever having these fluctuating timeout issues. Anyone else with similar issues who can tell me what might be going on? It's only a minor annoyance at worst of course, but it still bugs me a little.
