[HELP] My screen does not turn off.

I've got a little problem that is draining my battery.
When i press the power button, my screen turns off, but two second later it turns on into the lockscreen.
Already tried a full wipe to look if some app is causing the problem, but nop. it still had the problem.
However the weird thing is that when i use the phone it never turns the screen off. it does sometimes pop up the power menu, but that does not happen often.
I hope someone can help me, because it annoys the heck of off me that i can't even get 7 hours out of my phone w/ minimal use.

[Q] Backlight issues

I'm having an odd problem. When my G2 is sleeping (screen off, not charging) the backlight intermittently turns on and off. I'm currently running a CM7 nightly (#21) but have attempted to troubleshoot this by flashing several (non-CM7) ROMs, and the problem remains.
I've been unable to see anything in a logcat dump showing the screen or backlight activity.
Another symptom is that pressing any of the "hard" buttons (besides power) cause the backlight to momentarily activate, then turn off.
It behaves this way in any mode--airplane, wifi on/off, bluetooth on/off.
Otherwise everything else seems to function normally--as long as the screen is supposed to be on, it's great. Sitting on the table or nightstand flashing the backlight all night, no so much.
Anyone else had this problem, or is it time to start hunting for a "donor" device?

[Q] Cyanogenmod 10 - during a call that extends ~5mins, proximity sensor doesn't work

Device: S3 with CM10
Basically the title says it all. During the first few minutes of a call, I usually have no problem moving the phone from the face and then seeing the screen light up. However, after ~5 mins on the phone, if I move the phone away from my face to hang up or something, the screen doesn't light up at all. I tried wiping the sensors on the top with my clothes, fingers, anything, but the screen still stays off. Only after I press the power button or home key does the screen turn back on.
I tried googling this but haven't found any answers.
Thanks in advance, you guys rock btw.
EDIT: Is it possible this has to do with the Sleep settings? Additionally, what is sleep? I'm confused about that too.

[Q] screen not turning off

Strange issue
a new samsung s4 mini, stock rom.
the screen will not turn off. whenever it enters sleep mode, the screen blacks out for a second, then turns back on.
this happens when it goed to sleep automatically, or when pressing the powerbutton
tried factory reset, same problem (no extra programs installed)
installed a wakelock ap, but that does not really show a reason why it should be turning on?
Anyhting obvious i am missing, or should i just return this to the dealer.

Have you installed any app like "Screen ON"?
I ve got this problem from time to time, when I lock the phone it wakes up for 5s and then turns the screen off although I have had twice the situation where the screen was on all the time till I pressed off button again...strange.
Had this problem long time ago with Note 1 and somebody said that the phone wakes up if it looses the signal and searching for it again......
dont know......

Im not really sure but might as well try.
Have you turned on Daydream ?
You can find it in Settings 》My Device 》 Display
Make sure it is off.
If that hasnt worked, if you have a cover on take it off and then see if you still have that problem. Maybe the cover is too tight and its presing on a button.
If that doesnt work, then now lets turn off Smart Stay. Swipe down your notification bar and look for Smart Stay and turn it off.
If none of these have worked then I'm not sure :/
Hope your problems gets fixed.

-Any button or combination of buttons pressed will wake the phone.
-Pull battery and pop it right back in, phone turn on but screen and backlit buttons lit up for a micro of second and turned off. The phone still function.
-Pull battery and leave it out for a minute, pop battery back in.
