Is there any way to disable the power button while the screen is locked?

Yeah pretty much that's my question. I'm rooted 2.2 froyo.
I want to disable it for security reasons

.......why would you want to? you wouldn't be able to wake the screen when it turns off.
you can set a pattern or pin so like, if you are in college class you get up, people can't get into the phone unless they know the pin.
settings > security > setup screen lock > pin
or you can just buy a belt pocket at wally world for like 12 bucks

Yeah, gonna have to go with the above poster. That would make it pretty much impossible to turn on the screen to then unlock it.

I mean like to disable the option of turning off the phone when the screen is locked. And I'm saying day the phone is stolen even though I have cerberus installed if the thieves turns off the phone I can't track it.

"or you can just buy a belt holster at wally world for like 12 bucks"
seriously, this is why i never let my phone out of my sight or get away from me.
if you work in a busy place or in a busy place it's probably not the best idea to let your phone/laptop/anything of importance be left unattended to in the first place.

Yeah I try to keep it with me at all times. But so there's no way?

This sounds a little insane. There's almost no point, much less a way. So you have it stuck on. Now what? The battery is gonna be dead in a day.... Which would have the side effect of turning it off. If you're running GPS on it constantly, its gonna be dead in far less than a day. Maybe I'm not understanding this.

What if you get what you want.. and find a solution about your issue!!! Your next question would be how to seal the phone so the thief can't take the battery out.. I personally would recommend what Kiboe mention...

he basically wants to make it so a theif can't turn the phone off, otherwise his tracking app would be pointless
which is why i said, just to buy a freaking belt caddy from somewhere for cheap, don't buy them at the verizon store, no way in hell are caddy's worth 30 bucks

Lol thank you for understanding. I guess I'll do that then.

In that case I'd recommend "Where's my Droid". You send a text to your phone, it wakes it up and gets a GPS fix, then texts that to you. Unless the app is removed, there is no way to stop it from doing it's job. It works even when the screen is off.

Do you guys think we will get this mod????

If any of the devs feel like doing it, sure lol. I could see some battery drain issues though because that means the front buttons would have to be polling still when the screen is off.

I'm usually all for extra possibilities, but this one is kinda meh.
Why would anyone ever prefer sliding over pushing a hardware button once?

This would be great to extending the life of the phone's natural power button...but I'd be on to a different phone long before this button mechanism on my phone have a chance to think of failing. Maybe good for people who keeps there phone for over 2 years?

Might open in your pocket too against your leg. looks neat though

This would be faster. I hope someone ports the mod.

How would it be faster to swipe across all 4 capacitive buttons than press the power button? Pressing the power button takes literally a split second. Keep in mind this mod doesn't unlock the phone, it just turns the screen on. You still have to unlock from the lock screen like you normally would. I agree it would likely drain the battery because the phone could never fully sleep if it's constantly looking for input from the capacitive buttons.

Anything to make the power button last longer I'm for..

I could see the phone getting unlocked constantly in your pocket.

My screen times out often, especially while reading... I hate reaching for the power button. To me this would be easier. However 2 things will keep me away:
1. Battery Life concern
2. Unlock in the pocket
I would definitely try it

i have beenw anting this since the og evo...i dont have the biggest hands and loved how all the older android phones had hard buttons at the bottomt hat made it wake
PLEASE PORT THIS SOMONE PLEASEEEEEEEE

This port would be nice.

Battery Life Suggestions

Hi! I'll be going abroad in a couple of days and while I have tested most JB roms I'm not sure which rom has the best battery life. I'm currently using Rasbeanjelly and Trinity Stable 35 and I only got 3hrs of screen on yesterday (however I did have 3G enabled most of the time). Can anyone please suggest the best ROM for battery life ?
(Sorry if this has been asked before but I needed to know the answer with the latest roms)
Thanks

3h screen on is already decent for jb. You wont get much better.
Theres a lot of tweaks you can do. One of the most helpful ones is using a screen filter set at about 50%. Its good in the dark, sometimes in the sun you will wanna disable it.

Purchase an extended battery ASAP, they're awesome. Also, another recommendation is to buy an external battery that does at least 1AMP output.
Useful link for the battery.
Check out this item I found on eBay: http://pages.ebay.com/link/?nav=item.view&id=120832462058
You've pretty much done all you can software wise. Don't ever use auto brightness FYI, that seems to be a big thing that people do and wonder why there battery drains.
Sent from my Galaxy Nexus using xda app-developers app

I get over four hours of screen on time and over 12 hours of battery life with moderate use on stock jb. I consider this to be very good.
If you plan to use GPS a lot, an extended battery is recommended.

Samsung extended battery is quite nice and fits in most stock covers.

Think of it this way:
On your phone is a variety of sensors that go off only at certain times (an example being the sensor to the left of your camera, it senses when your face is pressed up against your phone during a call and turns off your screen, call some and cover it with your finger, you'll see).
Now, for auto brightness there is a little hole in the upper right on the back of your phone. Turning auto brightness on keeps this little "camera" on permanently. It causes the phone go run a constant series of scripts telling it to adjust the brightness over and over again and on the fly.
I guess that's the best description I can give, I hope that helps.

That little hole in the upper right on the back of the phone is a 2nd mic for when your recording video to cancel noise. The auto brightness sensor should be on the front of the phone, as there are 2 sensors beside the front camera.

I also recommend the extended battery, I bought mine from Verizon and I get about 17 hrs. I need to play with the settings a bit more and try other kernels. I also suggest to select "never" in the email app, not the gmail. The app seems to wake the phone up the most.

if you wanna try a new rom, try this it's mine i've a very good battery life with it.

[Q] Smart stay - yay or nay

so I have just recently purchased my note8 and Im still trying to get the hang of it. I notice that I frequently qet message saying that the smart stay can't detect my eyes.
I also notice that I rarely see the eye icon lights up (I assume its there to indicate that the feature is active).and one time, the screen went blank just right after the eye lit up.
maybe, speaking from my limited exp, just maybe, the smart stay works better on devices with smaller display as the variance of the eyes/ face orientation will be much smaller compared to on an 8"device.
While I understand the benefits, the question is how many of you find this feature reliable on this tablet? pls feel free to share your experience on how it performs on smaller devices.
Im thinking I might as well turn it off in exchange for some extra battery life.
thanks / Luke

Can't share any experience using this feature as turning it off was the very first thing I did after purchasing my device
I think the drain should be way too high since it uses the front camera all the time, doesn't it? Anyway, it happens maybe once a week that the display turns off when I'm actually looking at it - at most. And just before the display turning off it dims the screen, so there is still some time to react..

I find it doesn't work as well in the dark as my GS3 did under earlier firmware and I do often get the icon. But smart stay does work well for me. Unless I'm laying down on my side.

It checks every 15 seconds of inactivity to see if you're still looking at the screen. If you're not according to your front camera, it'll dim/shut the screen.

Mine only checks a few seconds before the screen is set to time out. Ie. If the screen is set to stay on for 2 minutes, it will check at about 1:50 of inactivity.
I kind of like it except, as posted above, it can be a little iffy in low light.

I really think it is almost completely useless and simply a waste of battery. I've also disabled lock screen. Nobody touches this tablet but me. When I use it I want it instant on, and when I'm done I turn the screen off myself. I hate my devices trying to decide for themselves when to switch off, and first thing I always TAKE THE POWER BACK!

Thanks for the feedback everyone. l have been trying it off and on but at the end I would have to agree that it doesn't work for me. I cant say how much power saving I get by turning it off but it feels good to know that some resources are relieved for something else.

I use it on my note 2 (8 months now) and note 8.... it doesn't burn much battery.... it works better on the note 2 because your face is exactly straight on the camera... On the tablet.. Usually we hold it slightly at an angle.. So the camera sometimes misses off

yeah I like it too. I usually only use it when reading on the kobo app but it does come in handy.

After reading this topic, I charged my Note 2 and disabled this feature to try to get more bvattery life.
The difference is like night and day. The screen consumes a lot less power (according to the JB's Battery widget) and the battery lasts much longer.

i've never used this on any of my devices. i always seem to have this odd habit of turning off electronics when i'm not using them

A big NAY for me, I just haven't been able to get it to work even a single time, keep getting the "Smart stay cannot detect your Eyes" message again.
Is it that bad, even in other device like the S3 or S4? S4 has so many features(like the smart pause based on it, makes me think I can't use it properly), any tips how to better the usability(other than the usual ones given by Samsung)?

Galaxy Note 8.0 need advice!

GT-N5110 wifi version. Ive had this device for 10 days. Out the box it was running 4.1.2 and seemed work great other than the occasional 3-5 seconds when screen would become unresponsive during normal use. After using it for a few days I decided to go ahead and update to 4.2.2 thinking maybe it would fix the screen issue. It did fix that issue but now im having another problem. After the device sits dormant for awhile the screen doesnt respond to touch but still works fine with the s pen. Ill turn it on after sitting all night and after swiping to unlock the screen it becomes unresponsive. I usually have to lock/unlock the screen several times before it will start responding. After it starts working I can be on it for hours with no more problems. But if I lock the screen an set it down for awhile when I go to use it again it does the samething. It seems like it has to warm up. I tried doing factory data reset but that didnt help. It is rooted also but the only thing ive done so far is get rid of some bloatware.(i didnt root it untill after the problem started). Anyone have any advice?

Do you have your note in a cover , and if so does it have a magnet.
Sent from my GT-N5110 using xda app-developers app

That does sound rather crazy, the unresponsiveness is out of the ordinary... did you try turning off a lot of the extra features built in by Samsung? another thing you could do is download Clean Master from the play store and take a look at your Ram use-age and clean out some cache files with it, this might help with the lag. The touch response could be hindered due to a case or screen protector... other than that the only thing i could think is if there was physical damage done to it before that could cause the touch screen to act that way.

Ummmm... I would have taken it back to the store and asked for a replacement.
That is not normal at all. even with the device's settings left alone, there should not be any issues with responses with touch.
Note... The pen feature is totally separate from touch. The screen has two different features, one being a digitizer for the pen function the other for touch. It is possible that during assembly that the connection for the touch screen is faulty, as a bad solder joint during wave process could make the connection heat related. As the device cools, the contacts contract causing a fault with touch operation. When heated up from normal use, expansion forces contact between connector and board for normal operation to function with touchscreen.

Thanks for the FYI. I was using the moko whatever with a keyboard and I got the freezes all the time. I was thinking about the official Samsung one but if that gives you problems then forget it. I almost sold this thing on eBay cause I couldn't take the freezes anymore. Now I use a tpu case with it and couldn't be happier
