G4 GT-I9505 problem random sleep while screen is on. - Galaxy S 4 Q&A, Help & Troubleshooting

Hello,
I'm looking for FAQ about my problem but I haven't found any answer. The problem is where I'm using my G4 I9505 randomly the screen turns off and I have to unlock again with the pattern.
For example using messenger while writing screen turns off. I press unlock button unlock with pattern and continue writing. I tried disabling the option witch checks if you are looking the screen but the problem is still present.
I use stock rom android 4.4.2.
Can you tell me if it's a software problem or if I have to go to samsung support? Maybe using custom rom?
Thank you so much!

Lock on Standby/S2U2 issue

I know this is a more general question but maybe there is an answer specific to our device. I've searched all over and can't find any solution.
All I want to have happen is to have the device lock when it goes into standby. Either by pressing the Power Button or when it automatically goes into standby, I would like the device to lock using the native locking in windows.
I'm running NFSROM's latest 6.5 ROM. I've used S2U2 for a while but for some reason with this build, when I wake the device, the home screen is shown for a split second and then the locking app shows. Maybe I need to fine tune S2U2, but I've tried many different solutions to no avail. Anyone else have this issue?
TIA

Lock screen bug

Hi Folks,
I've found a little bug in the lock screen ... i'm on the new rom, can't verify for the old one.
To reproduce:
Sleep phone, wake up phone and finally on the lock screen, press menu.
TADAA you're dropped straight into the home screen.

p13 thats always been like that?? well I could do that on htc before and after the new rom
Same here, no bug, just a way to get rid of the lock screen without whiping the screen
Oh Okay
I didn't know that was normal behavior.
Nice to know, thanks guys!
Kr,

indeed, that is the standard way to unlock android devices. This is exactly the same on the G1 and Magic as well.
it also works when you are on a phone call. When the screen turns off and you need access to the buttons, you press menu and up it comes.
Cool. This is my first android device, since there is no mention of this behavior on the lock screen, i thought it was a bug.
It's nice to know, thanks for the pointer !

[SOLVED] Unlock button not responding promptly after restart

Hi all,
I'm using Energy ROM with Cookie Home Tab, currently this one: Energy.BLACKSTONE.21916.Sense2.5.Cookie.Classic.DinikGlass.Oct.08. I have tried several versions, but lock screen behavior is still the same...
When I put my device into standby mode, it goes locked automatically, that's what I want. But when I turn it on I want the unlock button to respond promptly, without any delay. It is working correctly after flashing my device, but after first restart I'm not able to use unlock button immediately and I need to wait a little bit (1 or 2 seconds) and then slide the button to unlock the device.
Has anybody discovered the same behavior? How to fix this and use unlock button immediately after the display goes on?
Thanks,
Vladino
Edit: I'm sorry, I just woke up and missed the thread where it is solved: http://forum.xda-developers.com/showthread.php?t=587931

[Q] S4 lock screen: cannot swipe but can click on items

Hi everyone, first thanks to all the people who are willing to help others with their S4 problems!
I have Telus version of Galaxy S4 and it is basically untouched (i.e. no root no modifications).
I have had a problem with the lock screen for past couple of days and tried searching the forum but could not find any solutions.
The problem is this:
In lockscreen, I cannot swipe to unlock the device from time to time. No matter what I do, pressing power button to get to lock screen again, it just won't respond to my swipe motion to unlock the device. This forces me to hold the power button and then click on restart. For some reason it will responds to me clicking on restart but cannot read my swipe motions.
Does anyone else have any similar problems? If so, any thoughts on the solution?
The annoying thing is I cannot replicate the problem but it will happen once or twice a day.
Any thoughts are appreciated!

Weird issue: S3 Neo won't turn screen on once it has been locked

Yeah, so my friends S3 Neo running stock 4.4.4 has this weird problem: The phone will work completely fine but if you press the lock button, the phone will lock. Once you press it again to turn the screen on, the screen does NOT come on, ever. You need to reboot the phone to have the screen on again. Even tried flashing another stock firmware but still the same. Anyone know of a fix? Thank you!
