My Tab 4 turns itself on every night at specific time. I cannot figure out why, or what setting may be the culprit.
Every evening, I tap the power button to "sleep" my tablet before I put it in its cradle to charge. However, every evening at a specific time the tablet display lights up showing the lock screen, which wakes me up. This is making me nuts! I can't find any setting that would affect this behaviour, and there are no alarms set to "wake" the tablet at some specific time.
Any ideas where I should check?

Ok, so after doing all my searching and what not, it seems that for whatever reason the time it takes for the lock screen to time out is tied to the regular screen timeout.
What I mean by this, is when you first hit the sleep/wake button and its on the lock screen, but you don't unlock it, the time it takes for that screen to go to sleep is the same as if you had unlocked it and not used it.
For me at least, this is a major battery life issue. I like to leave the screen timeout at minimum at 5 minutes, because I use my phone's LCD as a flashlight quite often (LGP500 doesn't have a camera flash), and read websites fairly often. Also, I tend to keep my phone in my pocket (who doesn't?), so when walking or moving it's very likely one of the hardware buttons (sleep/wake, home etc.) will be accidentally pressed inside my pocket at least once every short while, basically keeping the screen on permanently.
I'd like to know if anyone has any ideas on how to change this.
Just as a side note, I realize it's possible for rogue apps to keep the screen from timing out, but I've made sure that its not the case here - when the timeout is changed to 15 seconds, the screen turns off at the correct interval.
Anyone have any ideas?
This might prove trivial, but I have not had success yet.
When I go to navigation mode, my display will dim after ~15 seconds (not turn off). Periodically, it will go back to the set brightness after ~30 seconds. This is while a charger is connected.
What setting do I change to cancel this behavior? I find it a feature when not connected to a charger or when not in certain applications.
....One thing to note and will likely work for me...
Testing in "Car Home" appears to resolve the problem.
I'm looking for a possible app that can automatically lock the phone regardless of what it is doing. I use the MHL to HDMI cable to output to my tv when I'm in bed and I like to watch shows to put me to sleep.
The thing is when the cable is plugged in, the phone's screen never turns off because it would turn off the tv display as well. The display just goes dim when it's idle. I can manually lock it and it will shut off, but I would like something that can send a lock command or a power off command after a certain amount of time, sorta like a sleep mode.
I don't like having my phone screen's stay on until morning even though it's staying fully charged. It's usually pretty warm when I wake up. Is there any way this can be done?
Maybe it could be done with tasker? https://market.android.com/details?id=net.dinglisch.android.taskerm&feature=search_result
I gave it a try and it seems like a really nice app, but I couldn't find a way to command it to lock or turn off the phone. There were 2 options I saw called "lock" and "system lock" and I tried both but nothing happened when the specified event occurred.
I'm tempted to try the HDMI on my Galaxy Tab 10.1, but I'm thinking it would remain on as well if plugged in. Thanks for the suggestion though.
so when ever the tab is fully charged the screen turns on and wont go of until i click the lock button.
i don't have power savings mode. timeout is set to one min. and no auto adjust screen power. 3.2 stock rom
i cant find any settings to adjust this specifically so i don't know what this is. i just don't like the idea of the tab sitting for hours with screen on
EDIT: also noticed that if i put to charge screen wont go of, just fades after the 1 min timeout. i must manually turn it of. i.e push lock button
Hi.
I haven't noticed anything like that when I have been using stock Rom...
If you put tablet to charge did the big-clock screensaver shows up?
If so, you must press back on the bottom tab to let it go away and then it wil fade out and turn off the screen after timeout you have set up in settings...
The only time when screen goes on after charging and stay in that state is when charging with Tablet switched off {big battery charging indicator show up...}...
is it the lock screen your talking about, if so then yes. tab is put to charge and locked. then when full it makes a sound then shows lock screen and fades a bit after some time, but doesn't turn of. screen is of until fully charged. then turns on.
Hmm... this doesn't seems to be normal. On my tab, when fully charged it just make a sound and doesn't unlock or light up the screen...
Which country are you from and what ROM are you using? This might be an unwanted "feature" of branded ROM from some operator/provider...
Maybe if you are planning to Root and give your Tab some nice new ROM from here, your problems will be solved...
im planing on rooting as soon as CM9 is done. im in norway. we dont have operators/providers screwing up our phones like in the states.
heys guys, i recently downloaded a calendar app that wakes my screen up when an event gets notified, fact is it just wakes up for like 2 secs.
in the calendar app settings you can decide how much time it has to stay awake, but it doesn't work at all. even if i set it up to stay awake for 30 secs, my screen gets back to sleep in like 2 secs, i tried to change every possible setting (display stuff, battery stuff etc) but i can't find a solution to it.
any idea pls? thanks
