Here's something interesting: there is a mechanical switch on the flashlight led that clicks with wear. It's actually quite cool. There appears to be a mechanical switch and an electrical switch in sequence. The mechanical switch connects the led when a program that may need it opens, and the electrical switch handles strobing.
I hear it when the camera app opens and closes, but not when the flash goes off. I hear it every time I toggle the flashlight, though. It's actually quite pleasing to the ears.
Anyone else experience this?
Hmm I put the phone up to my ear and toggled my flashlight widget a bunch of times but I couldn't hear anything. Tried it with the camera app too and still nothing. My ears are pretty messed up from concerts though, so perhaps it's out of my range of hearing

Does anyone know how to stop the screen from turning off during a call?
Move the phone away from your head?
Otherwise, why would you need it to be one when you're talking on it?
turn on the speaker, i think that disables the sensor.
This is a huge problem with 2.1.
In Android 1.5 on the Eris, you could push the TRACKBALL during a call to wake up the screen.
In 2.1, you only have two options. Pull the phone away from your head (often works, but not always, especially if you're trying to get through a phone tree, and often going back to the screen) or push the 'End' button.
If your phone's screen has been off LONG enough, the 'end' button will wake it up.
If it hasn't, the 'end' button will both wake up the screen AND END THE CALL!
It's a huge risk, and unnecessary. THE MINUTE the OTA comes out, I'm calling HTC about it, and asking them.
Oh, and for what it's worth, Screebl Lite takes care of this.
Just set up Screebl, mine is like 20-90 degrees for both portrait and landscape, and for the in-call activity, I have it not be active when up to my ear.
Screebl works GREAT to keep the screen on properly during a call.
Still calling HTC about it. That functionality should be built in better, or at least give me a way to wake up the screen when it gets stuck.
That is exactly my problem. When i go to wake it up to navigate the through menu options it hangs up alot. Very irritating! I will try Screebl.
Thanks!
you can also press any of the two volume buttons and that will wake it up without any bad effect except for a volume change.
Good tip about the volume buttons, I wasn't aware of that trick.
thanks
sometimes my phone won't wake up when I pull it away from my ear, but I usually just move my hand over the prox sensor and then back and it generally wakes up.
Keep Screen
This is a good thread. I had this problem too. After reading your posts I used the copy of KeepScreen that I already had and it worked also! May be my imagination but proximity sensor seems more responsive too.
During a call, if I keep my HTC Hero close to my ear the touchscreen becomes none responsive, meaning I can't touch stuff by mistake. If I take my phone away from my ear, I can touch the screen again.
Which is fine. This is how it's supposed to work but there's a problem:
If a call lasts longer than 1 minute (or however long you set your phone to automatically go on stand by) the screen goes dark, which is fine in most cases but sometimes you need to look through your phonebook during a call or put the person you're talking to on hold so you can answer another incoming call, etc.
Of course you can just press a key and the screen lits up again and you can do all the above mentioned, but pressing a key like the "Reject button" (which normally unlocks your screen) will not only lit up the screen but also cancel your ongoing call.
Similar to that pressing any key might also have an undesired action, which can make any during call operations frustrating.
Can the screen be configured to behave like the iPhone's (or Nokia's touchscreen phones for that matter)? Meaning when the sensor detects the phone is close to something (like your ear) the screen goes dark to save power and it becomes non responsive, but when you take it away from your ear the screen lits up and becomes responsive again?
The change isn't that dramatic, go dark instead of just becoming unresponsive (waiting 1 min to go dark) and lit up again when the phone is no longer close to something, instead of remaining dark.

Take a look at the app "proximity sensor" as the hero doesn't have such a sensor. The app uses the light sensor to emulate it

I took a look at the app online, I'll try it out.
I didn't know the Hero didn't have a proximity sensor but whatever 2.1 does it does it well, I don't accidentally press anything, the touchscreen gets disabled.
I'm upset about the fact that the screen stays on and goes to standby after a while instead of being dark when the phone is near my ear and lit up when it's not.
The phone knows when it's close to something, it deactivates touch input, I just wanted it to also turn off the screen and turn it back on when it's not close to anything.
Intermittently, when initiating a call, the screen goes blank/ black for 5-6 seconds, or longer, and does not wake up. During this time, the phone does not respond to any tactile or soft input, but ringing and other audio continues to emit from the earphone.
I do not have any sort of screen cover/ protection, or any other obtrusion to the proximity sensor.
This is extremely annoying, as sometimes, I would like to immediately hang up, or place the call on speaker, but cannot do either as no input registers.
Is this an isolated issue to me, or CM7 on the AT&T SGS2? I am not running any special apps or background services.
It 'feels' as if this is mostly caused by some sort of lag, as it does happen intermittently. i can't pin down a particular pattern during which this persists. Anyone else experience any similar symptoms?

this same issue is what made me drop cm7 and go to UnNamed
I had it and would just hit the power button to turn it back on.
Dropped this on their forums:

Hi gurus!
I made a stereo FM transmitter circuit that fits into a phone. I'm turning that transmitter on and off via a power button press of about 6 seconds. Instead of doing that I would like to be able to toggle the transmitter with an App. Now the main question is how to get an on/off signal from an App. Since I would like to build this into my Moto G my idea is to use the notification LED for it.
Notification LEDs can be dimmed, I did not measure it yet but I presume the LED is driven with a PWM signal.
So here is my idea:
- drive that LED with a very low duty cycle PWM continuously to keep the transmitter ON, like 10% for example (to save current), and when the uC on my circuit gets that signal for some seconds it will turn on the transmitter.
In other words, whenever the LED is driven continuously (low duty cycle PWM) for more than a few seconds the transmitter would be ON.
The notificaion LED is used by other applications too, I know, but I've never seen a situation where it's continuously on, neither fully lit nor dimmed.
So question is , is this feasible, how difficult would it be? I do not know anything about Android programming but I may be able to detect a constant duty cycle for some seconds on that small microcontroller.
I invite you to watch the video I made here : https://www.youtube.com/watch?v=BACdpATCpJ0
or to have a look at my Instructable in order to understand what I'm talking about: http://www.instructables.com/id/Cellphone-FM-Transmitter-Retrofit/
Thanks guys
Hi,
I sometimes use headphones for calls and keep the phone in the pocket.
Power button is hard coded to disconnect the calls so it's difficult to turn off the display during a handsfree call. It's a stupid decision on xiaomi's side. I now have placed lock button in the notification panel just for this purpose.
But the real problem is that, this extra sensitive screen wakes up in the pocket with some movements and as it's already unlocked because of the call, sometimes the call gets disconnected.
Is there any solution? I don't want to disable tap to wake up function. This problem also persists with audio navigation with Google maps.
