lock screen timeout tied to regular screen timeout? - Optimus One, P500, V General

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?

Smart Stay functions

Hey Guys,
Initially before I got my phone I had another perception on how smart stay works and was a bit disappointed...
My thoughts were, that if you are reading something it checks up on you if you are still looking = Screen stays on and if you look away it turns off.
The breaking point in what I thought was, that after the screen has shut down and you look at it again (Lets say a time frame of 5-10 Seconds) it turns on again.
I hope some DEV reads this and could make a MOD or something like that. Would be really cool and I dont think, that programming that is that tough.
Regardless of this I would love to have Smart Stay as a toggle option in the 15 Toggle mode or something, is that possible?
Thanks in advance
think that you have put your phone aside after looking at it. And it will have to monitor your eyes on that time too. Too much battery drain because camera needs to be on all the time! this is why samsung didnt enabled this!

The camera does not need to be on "all the time". The way it works is as follows:
- The screen timeout is set to a certain time - let's say 30 seconds. After 30 seconds have elapsed, the screen will turn off if Smart Stay is not activated.
- If Smart Stay is active, after 30 seconds the camera will switch on and determine whether you are looking at the screen. If it determines you are, it will trigger the screen to stay on for another 30 seconds, after which it will do the same again, and so on. Once it has confirmed you're looking at the screen, the camera will switch off again.
Hence in fact the camera only needs to go on for a very short period of time - just enough to see your eyes, basically. You'll know it's doing this because it briefly shows an eye icon in the notification bar.
Yeah and I meant that after the screen is off it just should monitor for another 30 seconds or so

Which would increase battery drain tenfold.

ok lets say screen is turned off and camera is checking eyes once every 30seconds. what if I happen to look at it on the 15th second
i have put this in smart stay threads before, if only people would search before asking questions.
anyway, in order for smart stay to work well this condition must be met - open front camera and look at it if you can see your face and it isn't darkened then smart stay will work well. because some may ask that smart stay doesn't work even if lighting is good, that is because your face is darkened because of shadow and you are at the back of lighting.
if that condition is met then :
1. smart stay should be enabled obviously. set screen timeout to 15 seconds.
2. look at screen, you will see in 5 seconds the eye icon for smart stay will light up
3. turn your phone at an angle away from your face but enough that you can see the eye icon 5 seconds later.
- this time the screen dims but not turn off.
4. face phone screen again, 5 seconds later eye appears the screen brightens up.
5. repeat step 3, screen dims. then this time remain not looking at screen.
- after dim, 5 seconds later eye checks again and detects you're not facing screen thus it turns off screen.
now some will be thinking, having the front camera turn on at intervals will just use more battery. the thing is,turning the front cam to sense your face for just about 2 seconds at intervals won't consume as much battery consumed as compared to the display still turned on for 15,30seconds,1minute or more even when you're not using the phone.
purpose of smart stay:
1. already well-known since this is what they advertise for this feature, keep light on so you don't have to annoyingly touch the screen at intervals you think the screen timeout is nearing so as not to be inconvenienced by the screen turning off when you are reading or browsing.
2. THIS IS THE MAIN PURPOSE - to turn off display way before the screen timeout because there's no use having the display still on when you're not using the phone. we all know the display is one of the things that can drain battery fast. this is very helpful for those who set there screen timeout to 1minute or more.
note : the time interval for smart stay checking/eye appearing is different for the screen timeout interval you set.
a bit harsh but quite correct, he took time out to give you an explanation, and a very good one, a hit on the thanks button is what you should have done! Nice one radeon :thumbup::thumbup:

Also, don't forget to mention "SMART STAY doesn's work in dark". It can't see your face well.

[Q] Keep app running with screen off

Ok, I have a voice changer app that I want to use with the screen off. Ideally I'd start the app, turn on real-time processing, then turn the screen off. Currently, it only runs when the screen is on, as soon as I turn the screen off the app stops all voice processing. Screen needs to be off so the battery will last longer, and so the settings can't be changed accidentally (so touch has to be disabled as well).
I either need the app to keep running in the background, or have the screen turn off but not actually locked (I dunno the right term, but if the screen was off and didn't accept touch input, but the phone thought the screen was on...that'd be fine).
Closest I've found is to edit the AndroidManifest.xml file to set it persistent, then make it a system app. This will take me a while to figure out, and not even sure it'll work.
Is there some simple solution I'm overlooking? I've seen an app that turns off the screen with help from the proximity sensor...but I want the screen off whether it's in my pocket or lying on top of a table.
Edit: I tried some apps that use the proximity sensor to turn off the screen; as soon as the screen goes off, the voice changer app just stops. I have no idea what's triggering it (if the phone is actually entering a sleep state, or if the app is specifically watching for the screen to go off and suspends itself). Thought that might be a workaround, but nope.

[Q] / Idea about how wake lock works.

So say for some odd reason you have your screen time out on 5 minutes, phones on silent you get a text. It wakes your phone up for 5 minutes. I have a rough idea of separating the screen time out selection into two. A screen time out set for when the end user unlocks his or her phone and a wake lock induced screen time out. Now I know there's anti wake lock apps but the idea is as I stated a set screen time out for a user induced wake lock and app induced wake lock. This idea popped into my head randomly as I don't leave smart stay on so I max screen time out to watch video's and sometimes luck my phone on silent for getting to change the screen time out back. Anyone have any insights about this.

Lock Screen Display Timeout Issue

So, I just exchanged my s6edge for a new unit today because the old one had an issue with tone unevenness and extreme yellowing in certain areas on the screen. Anyway, on my new one when I just click the power button to check the time or notification's, not unlocking the phone or anything like that, the display just sits powered on on the locksreen. doesn't time out or turn off. I have to do it manually. Idk why this is happening all of a sudden as it never happened on the old one or any other phone I've owned for that matter.
Any ideas?
I have exactly same problem. But it is software issue and lock screen timeout depends on normal display timeout. I dont know why it is done like this. Ussualy is lock screen timeout about 8 seconds and it is not depend on normal display timeout.

Is there an app to lock the screen with timeout?

I'd like the screen to stay on long enough to give me enough light to see how to put the phone in a little niche at the head of my bed, but I'd like to be able to put it there without accidentally activating something on the touchscreen. Does any app exist to lock the screen in N seconds and ignore all touch activity during that time? Just wondering if one exists before I try to write one.
