normally when you place a lid over a phone the screen goes off and it locks soon after (proximity sensor?) but mine doesn't seem to be doing it.
am i missing something or does it just not do it?
It doesn't do it by default unless you are in a call.
There are lots of apps on the market which do it though (at some cost to battery life as it keeps the proximity scanner running).
Just search for "screen off proximity android" and you get a heap of them.
Some are free like this one -https://play.google.com/store/apps/details?id=com.skyarmy.sensornearcover&hl=en
ah, cheers.

The Hero has an ambient light sensor, so I assume this is possible. Like the iPhone and Palm Pre do during calls.. can the Hero's screen turn off when the phone is up to my ear and turn back on when I pull it away? Currently it does not.
Not that i am aware off, there is a free application on the Market called
"Shake Awake" which is useful but the odd occassion it doesnt work for me.
There are a couple of threads that are already covering this subject....

I have Speed Rom 5.1 on my Amaze. When I am finished with a call, the screen stays black. I try to hit the power button, but nothing happens. I have to remove my battery in order to reboot. Can someone shed some light on why this happening? I am thinking that it may have something to do with my CPU Tuner settings, but I am not sure.

Probably that or a bad flash, just reflash, see if it solves the issue.
Most likely it's something simple, like an issue with your proximity sensor. I know there was an app that could calibrate that but I forgot what the app was.
Stock Rom - Black screen while phoning
There is a similar problem on my wife's phone with a stock rom (not rooted Amaze from T-Mobile). When making or accepting a call, the screen will instantly go off even without leaning the phone against anything and won't turn on unless the power button is pressed. Sometimes the screen would turn on by itself after a while after the other phone was hanged.
I've downloaded AndroSensor app: the proximity value does't change even when touching the area near the earpiece. It keeps showing ( 0.5mA ) 3.5 in.
I've found a thread which is there since april 2012 and describes quite a similar problem.
okay.. i just the original post date for this thread.. please don't bring back threads that are 6 month's old which issues might have been solved already since no ones been posting in it for 6 months...
(anyways) this is what i was gonna say
on my current s3 when my phone is placed to my ear it cuts off the display.. and if you pass your hand anywhere near the sensor's to the top near the camera it cuts off the display.. maybe there's a feature like that enabled on the stock rom also.. or you could possible check with the system settings to see "screen" on/off settings in display or power saving mode.. or something...
Thanks for the answer. I didn't notice that the thread was that old. I think I will keep up a newer one. But the current issue isn't likely to have been solved.
The problem doesn't seem to be triggered by wrong sensor measures (because the screen will go off even after disabling the sensor) nor does it depend on the rom version (same thing on the CM10).
Resolved:
It will sound stupid but I have found a simple solution:
I have just wiped the screen in the upper left corner where the proximity sensor is located and it started behaving normally. Though I don't use any protection tape on the screen it seem to have become less sensitive because of mud or sweat.
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.
I found that a lot of the time, when I take my phone out of my pocket and open the flip cover, double tap to wake doesn't work.
I played around with this a lot and I've figured out that if I wait a few seconds after flipping back the cover, double tap works.
If I leave the phone out on my desk with the flip cover open, double tap always works.
So the problem seems to be that the flip cover of my case is blocking the sensor (proximity?) on the face of the phone. I guess that sensor needs a few seconds of light before it wakes up and recognizes the double tap to wake.
My question is - how can I change this? I'd like the sensor to stay awake all the time so that I can double tap the screen the instant I flip open the flip cover.
Any ideas? This seems like maybe something the xposed framework could do with the right module.
I don't think it relies on light at all.
My phone works with knock code in the dark just fine.
Also, doesn't opening a circle case usually turn the screen on?

I can confirm that covering up the light sensor with your thumb for a few seconds while the screen is off prevents Knock-on from working even after multiple attempts. Mine allowed knock-on to work instantly after removing my thumb. So I'm not sure about the OP's problem.
Coming from a OP5 with a separate fingerprint sensor (rather than under display), I'm used to being able to unlock the phone just by placing a finger on the sensor - even when the display is off.
On the 10T, the sensor only seems to work with the display is on, so I need to jiggle the phone a bit too wake it and then present my finger.
I found a setting 'fast unlock' which reads like the sensor is always active however I can't see any difference and pressing when the screen is off does nothing.
Anyone seen this / know how to get it working?
(For context, this is mostly an issue when I leave the phone on the desk and want to check something without moving the phone. If I pick it up then it wakes up and sensor works as expected)
