Has anyone noticed this, especially in the dark, whenever you'd press the power button to activate the screen again a dim red light can be seen right side of the camera. No idea what the purpose is as it's so dim...

It's the proximity sensor. Detects whenever an object is nearby and performs it's action. It's the sensor that's needed to turn the screen off when you have it up to your ear while on a call to prevent any accidental touches from your cheek. The reason it turns on when pressing the power button is due to the adaptive brightness setting if enabled. It automatically dims/lights the screen depending on the environment and ambient lighting around you. The proximity sensor is what controls that.

I have a disability so I have weak hands and limited finger dexterity. I am not able to hit the tiny hardware power button and volume button on the HTC EVO. It also seems most new 1ghz android devices have the same setup for waking the screen by power button only, so for many with disabilities like me, it will be a problem for most of the new capacitive screen phones.
Is there a way to modify the OS to wake the screen from touching the screen or the capacitive buttons?
Or a way to dim the screen 90% and go to lockscreen, to save on battery life?
Even better would be a voice wakeup home screen feature with a magic word like "Android" or "Droid".
I know turning on the screen by touching it or the capacitive home row buttons is not practical for everyone who puts their phone in their pocket, but many of us in power wheelchairs mount it to our chair so it is never in a pocket.
My wheelchair has 2 GRP-22 12V batteries, so I could get power for all day very easily. I know the screen can burn out at some point, but I usually upgrade every year or sooner anyway. Id just rather not have the screen lit all day.
I have at least 50 friends around the country with the same physical issues (MD) and there are thousands more, so this is a huge need for future smartphone users with disabilities.
I'd appreciate any input and if any of you programmers out there want a new challenge, I am glad to help test it!
Thanks!
Cyanogenmod roms have a setting for using the menu button to unlock the phone. You have to root your phone to install it.
Edit: strike that, it's late and wasn't thinking. It only bypasses the unlock screen. There is an app called no lock that will let you use the camera and volume buttons if that would be easier to unlock.

Yep, NoLock from the market can awake the phone with the volume buttons.
Yeah the volume buttons are not any easier.
I may be able to use the power button if I could flip the phone screen orientation around so the power button is at the bottom.
From what I understand, the capacitive home buttons are part of the screen so if the screen is off, the buttons off. So what I am envisioning is setting the phone to timeout to lockscreen and dim down 90-95% so the screen is dark, yet the capacitive home button will work. Any programmers think that is possible?
hi
i had a question re locking and unlocking the screen. At the moment i press power button to lock the screen. then to unlock i press power button to wake up the screen and then move the onscreen ring to unlock the phone.
My previous phone was xperia arc s and had three hard buttons on the bottom which i would press to wake up the screen. I quite miss that, especially for unlocking the phone.
any alternatives other than to always keep the screen awake!
ta
"Screen off and lock" for turning it off. Works very good.
For turning it on I've seen a few apps that use the proximity sensor (i.e. put the phone with the screen against the table and it switches off, pick it up and it switches on). Not a great battery drain, but I don't know if leaving the proximity sensor always on could damage it...
Some ROMs have a setting for waking the screen with the volume rocker, and there are also a couple of kernels that have "sweep to wake". Thats where you sweep your finger across the soft keys at the bottom of the phone, from one side to the other. Other than those two thing thats about it for alternative ways to wake the screen.
Hi there.
I've got a hardware issue with my Nexus 5... the famed powerbutton stick issue.
Well, I'm better at hardware than software so I have a question. Is there a way to program or use an app to have an indicator for whenever the power button is activated? Such as having the LED light on the N5 light up whenever the power button is pressed? Or maybe have an indicator on the screen of the phone? The LED would be preferable, as it is clearly visible even when the screen is off.
This will help me see if the power button sticks and try to save it before it reboots. I've already minimized it's use by using a proximity sensor app to wake.
Any other help would be great!
Thanks
You can use the Galaxy Button Lights app to turn off the touch key lights but is it possible to simply control the brightness of them?
They're rather bright when you're in bed in the dark.
Has anyone figured out a way to dim the capacitive buttons? Are the LED's used by Samsung even dimmable?
Hi all
I have a Note 10+ (from launch, in the UK) and if I'm on a call and take the phone away from my ear to end the call or press a number the screen doesn't wake up at all, I have to press the power button to wake the screen.
Is there anything I can do to fix this as it's incredibly annoying
Thanks!
Easy, calibrate your sensor, check this:
