no lock screen on galaxy s i9000

My galaxy s i9000 is acting strange... normally, when i press the power button to unlock the screen, there is a lock screen which i have to unlock it by sweeping it, lately this lock screen suddenly disappeared and and when i press the power button it takes me directly to use the phone, so how can i bring back this lock screen?
Please any help will be appreciated. thanks in advance

Maybe you have installed an extended statusbar and deactivated lockscreen.

What firmware/rom are you guys using?

Hey
Which rom u using??
And try a factory reset..if that dont work then reflash the rom/firmware..
Plus check the settings for lockscreen...

Power button menu stopped working.

Hello all. When I push my power button i feel some haptic feed back but menu doesn't appear. I'm running phoenix ultimate with suckerpunch voodoo kernel. Been running this same setup for weeks now. Is a problem like this rom or kernel related?
I had to pull the battery, to turn it off but when i reinstalled it turned back on fine, but still no power button menu.
Suggestions?

Yeah, I've experienced the same thing also, few times.

I think this happen when you have notification.
Waiting for firmware update.

For me this is compleatley random, once per 20-50 off's.
No notifications, no difference whether i switched off thru button or thru widget (i use "Screen Off").
So if some one have an idea how to stop this, please help

Maybe you have a faulty unit?
Are you rooted??

I hardly belive it is fault of my unit.
I spoted it with original firmware and now ater unlock, root and revolution 2.2 (basicaly same firmware with modifications i like )

Actually i think Sony's devices get that issue. And that is because of the app is not compatible with the rom.
My solution: turn off the lock screen!

Same issue here too, I believe it is Sony's problem, hope a new update will solve it..... turn off lock screen works but hate to use this way.....

I don't think is the low battery mode, I don't have it turn on and it still have the problem, I think it is when the phone get some notifications or go to internet for data then the phone with get activated but it does not go back to total sleep mode.....

low battery mode for me. I've got it set at 15% and when it charged back to that amount the backlight turns on.
Just a glitch for me and a waiting firmware update.

[Q] Phone screen not turning on after screen timeout

Hello, I'm currently using the P.A.C Man 22.1.0 ROM and sometimes when I leave the screen to timeout on itself, turning the screen back on using the power button wouldn't work. Most times I have to remove the battery to get the phone going again, but when I do, I see that the battery percentage often drops 10-20% of what it was before. Is there a reason why this is happening and is there a fix?

it is a bug .. so flash it again or try new rom . hi thanks i i helped

ah okay.. in my case i wanted to turn it on (from stand-by) and it didn't react. or actually the screen was very low-lighted black. after i push the 2nd time the power button the screen is completely black and the 3rd time i press it it works fine. not that bad but sometimes really annoying

Same case with me many times and thats annoying

yes, but i'd like to know, where exactly this problem comes from? if it is a problem in the system couldn't there be developed any tweak or similar?

It is a bug in the software. It does wakeup the phone and i am able to enter my patern to unlock it but i cant see it. After i turn my screen off and back on again it works normal. This happens only after a very very long time of deepsleep. However my screen turns on when my alarm goes off at 7:30 am

so far I can confirm this is a bug on sony's stock rom, as I have tried MIUI & CM 10.1, and right now using CM 10.2, the problem doesn't arise. the screen unlocks perfectly normal.

yes that bug is still there, although it isn't that frequent so not a major problem, it can be annoying ...
goes away if hit the power button again to turn the screen off and again to turn it on to the lock screen.
hopefully it'll be fixed in the next update.
regards

True that!... I do face this some times.. the screen lights up but its black...
need to press the power button again so that it gets locked and wake it back to normal pressing the power button again...its annoying.!
