Phone sleeping problem? - EVO 4G General

I've noticed this happen to my phone a couple times. I'll walk into a dark room and my phone, which I believe is asleep, the button lights will come on but the screen is off. Then the lights will go off. When I press the volume buttons the lights will come on again. The screen stays off the entire time.
Perhaps our battery problems are because the phone is not fully asleep because the light sensors are still active reacting to changes in ambient light even though the screen is off.
Anyone else experience this?

8125 stuck with no disply

Today I had an alarm set, when the alarm went off I tapped hit the power button on the top of my phone to turn the screen off (and hopefully the alarm... but only the screen went off). The alarm continued to go, but no matter what I did, I couldn't get the screen to come back on.
I can fully interact with the phone (as if the screen was on). For example, pressing talk twice redailed my last call. Pressing power prompted to shut the phone off (could hear the "blurp"), etc.
So, after shutting the phone off (or resetting with pinhole reset), the display works fine while it is displaying the "Cingular - Raising the Bar" nonsense. As soon as that screen is done (where it would have normally showed the today screen), the screen just goes off...
Any ideas?

nevermind, when I put it under a bright light I realized the screen was on, the backlight was just off... somehow I must have hit some shortcut to turn the backlight off.

Don't sound too relieved...
Say hello to the Backlight bug.
You're backlight will keep setting itself to the lowest setting after every soft-reset, when you let it go into stand-by itself.
I'm still sufferering from it. It started when i first installed PocketZenphone.
So just want to give u a warning. Everytime you reset your phone, remember not to let it go into standby itself. Either tap the power button and turn the screen off, then turn it on agan. Otherwise, the Backlight will go to low again.

SPV M3100 phantom backlight?!

ok well during the day and everything its fine but now as I type this message and when I'm generally in landscape mode using the keyboard my hermes backlight has a life of its own it turns on and off randomly...
no its not power saving, I'm sim unlocked but I now run the 1.09 bootloader and latest HTC rom and I'm getting to wits end. sometimes it can be fine other times not.
some may think what is he on about but it is happening to me and I don't even think its a hardware fault either or at least I hope not as most of the time my backligt behaves! anhone got any bright ideas as to what could be causing the flicking?
I have had a problem where the keyboard, when slid out, does not light up. Is this what you mean?
If so, I went into the control panel, switched it off in the settings and then closed it all down. I then went back and enabled it, and did a soft reset when it had all calmed down. No problems since
HTH
I get a similar problem, when I have read a message and switch to landscape mode and start typing, the backlight turns off and as i continue to type it will switch itself back on.
its a pain in the arse and is one of the bugs im hoping to get rid of on a rom update.

The keyboard has a light sensor. It will only light up in dark conditions. Maybe yours is playing up, or the light conditions that your using your phone in may be the cause.
I turn my sensor off so the backlight is always on, Settings---->Buttons----->Backlight
S.K.
Its the screen backlight that goes off, not the keyboard lights.

Display goes on and off during calls

When I'm on handsfree during a call and trying to access the phones menus or programs, the screen first lights up after pressing pwr button, stays on for about 0,5sec, then goes black, then flickers on again, then off, then on again, and then off!
Sometimes I manage to get it to stay on by pressing on the screen repeatedly during the first 0,5sec. But usually I go through that whole procedure and have to repeat it until I manage to access the phone.
Anyone experienced the same thing? Only happens during call.

Same thing here, I use a BT headset. It is quite annoying.. I think it is trying to shut down the screen, because of battery saving. But I want to use the phone while speaking
Could have to do with the proximity sensor maybe?
Yeah it is to do with the proximity sensor. To solve this issue I try not to hover my finger over the top of the phone where the speakers are located (I think this is where the proximity sensor is placed).

if u look at the phone in bright sunlight you can see the sensor

Idle phone lag

Idk if this is effecting anyone else, but when i go to idle the phone by hitting the power button it seems to lag for a second or so and then turn the screen off. The touch buttons light off and then a second later the screen goes black. Just wondering if this is just my phone or if thats how the phone is.

Screen flashing when pressing home button

Hi,
I've been having screen issues with my phone. First green lines started showing on the screen, I turned auto brightness off, and it fixed the issue. But now when I want to wake my phone, it flashes white, but the screen stays off, and it does this for~3 more clicks, the fourth one turns the screen on though.
I'm on stock by the way. Not rooted.
Figured I'd ask before taking it to Samsung.
