Did anyone notice that during the call, the screen isn't actually turned off, the backlight is still on, it just shows blank screen. You can see this if you are in a dark ambient because of the backlight bleed on the screen.
So, while you are talking, you will lose battery charge on call and on screen backlight. I don't think it is an economical way of spending battery juice.
So actually the screen is on the whole time during the call, you just can't see it because there is nothing showing on the screen...
Or is this just my device?
X10 2.1 nordic.
I noticed that, anyway during a call, it obviously drains the battery even though the screen switched off & the use of the Proximity sensor is to switch off the screen during a call to prevent the screen from touching than the economizing the battery
I noticed a big improvement of the battery with the 2.1 Update.
I've noticed it too, I think this would waste more battery? or is it the opposite?
Of course it uses more battery power. I can't rememeber if the same situation is in 1.6. Can anyone check?
It does use current, but i think its a minor amount. The reason why they leave it active but black for example, is that if you need to quickly access the dial pad you can do that, without waiting for a second or two for the screen to power on.
I recall back on 1.6 at times it felt like eternity that it would take to bring up the dial pad during calls. I'm not sure but check to see if the screen does in fact turn off completely after a certain duration, since that would be ok.
Nope, it doesn't turn off and I wouldn't say it's a minor amount of power, because the screen is one of the most power hungry components in our phones. So if you are in a call for say 30 mins just think how much battery that would suck out. And for me, for no good reason, when I'm on the phone I don't need the screen, that is why the proximity sensor exists, to turn the screen on and off
I understand, but you have to understand how the lcd works. Producing colours or tints cause the device to use more power. The brighter the colour the more power. Since white is the brightest tint or colour, whichever you prefer, black being the opposite would use the least amount of power for the screen being on. Unless this is a type of lcd matrix that uses most power with black I read about that before somewhere. But I highly doubt SE would do that. But considering its a concern of yours there might be an dialer app that negates this hmm.
At the Sony Ericssons products Blog there was a video about the new features at 2.1
It tells also that you could press the Power-Button to turn off the light during calls.
I´ve not testet this yet, maybe of you could test this. ;-)

It does not take a second or 2 for the screen to come back on. Just test it yourself by pressing the power button, it comes on within 1 second. On a side note, in the 1.6 days the screen would stay on completely and if you press the power button it hangs up. That was a terrible implementation.

Im on 2.1, cant check it anymore. It was rather sluggish for me on 1.6. The difference may be that I had pictures for all my contacts. I like it just fine.
Yes, you can turn the screen completely off by pressing power button, I've just tried. I don't understand why do I have to do it with my finger when I have proximity sensor that works just fine when it wakes up the screen from complete power off when I move it from my face. Seems like a bug to me.
LCD screen consumes the same amount of power no matter what image it is showing, black or white, so as far as I'm concerned showing black screen during a call does absolutely nothing for me, especially not for my battery. This is so trivial that I can't believe they missed it. Or maybe some SE engineer thought X10 has AMOLED screen so it doesn't consume power when it's displaying black...
Personally, I prefer the screen turn off compared to the screen lock in 1.6 as I had a hard time unlocking the screen lock when you need to use the dial pad when on the phone.
So when you are on the phone, the screen turns off and when you move your phone away from the ear, the screen turns on.

You are 100% correct, my mistake, lcds do use the same amount of power due to the backlight. I was just on the phone for 50 minutes and my battery went down by 5%, so i think its not bad at all. I was even on wcdma/gsm.
Drop SE an email to inquire on it maybe?
Well, maybe I'm exaggerating, but this kind of screen backlight beahaviour just isn't logical to me. You say you lost 5% on 50 min call? Hmm, that really seems low...
Where can I send inquiry to SE?
i have the same problem guys.....any solution yet?
working on a more accurate solution atm.

During a phone call, my proximity sensor doesnt seem to be sensitive enough. The screen turns off when I hold it to my ear, but when I pull away to look at the screen and interact with it, the screen either doesnt turn on or it will flash on and off again repeatedly. It seems that the phone cant detect that it is not near my head any more and should turn the screen back on.
Generally it wouldnt be a big deal since the screen does turn off when its held near my head, but when I needed to use the dial pad for a menu prompt it got really frustrating when trying to press in numbers with the screen switching on and off. (I just called Verizon CS recently and navigating through the menu was a pain with this screen going on and off).
I'm coming from the Samsung Charge which was very responsive: when you pulled the phone away from your head, the screen instantly turns on for you to press in keys or hang up. With the Rezound, it doesnt turn on most of the time and I have to press the power button (which will turn it on and then automatically off again...). The problem is alleviated if I'm in a very bright place (direct sunlight) so my guess is that the proximity sensor may not be sensitive enough to detect the difference between darkness and low lighting conditions. I'm sitting in a room with a 26W CFL lamp (so not too dark) and the Rezound has trouble turning the screen back on during a call when I pull the phone away from my ear.
Was wondering if anyone else exhibit this condition or if its just specific to my device (in which case I'll have to give Verizon a ring to get another replacement)?
I'm having the opposite problem. It unlocks itself a lot up against my head. My thunderbolt did this so bad I got a replacement thinking it was a defective proximity sensor. But it wasn't and I got in the habit of manually locking the screen on calls. But now my rezound does it but not as bad. I think htc sucks with proximity sensors cuz auto brightness is never programmed properly. It doesn't go dark enough compared to Samsung and motorola phones with auto brightness on. It only has about 3 brightness levels like in the HTC brightness widget, whereas stock Android has 5.

I'm having the same problem. The sensor would force the phone screen off as soon as I make a phone call. The verizon rep had me hard-reset while I was on the phone with her. The same symptom arises after the hard reset and the phone is brand-new.
I had to reset to get her to send me another rezound replacement.
On this replacement, however, I'm having the same issue again. My gf's rezound doesn't seem to have the issue.
I'm having a second replacement sent now. This is pretty annoying.
The interesting thing is the issue comes and goes. One day the sensor wouldn't respond, and other days it works fine. Although I would say that the issue deteriorates over time and never improves.
I've got a recurrent problem with my Desire X which seems to have two parts, and doesn't seem to correlate with any other post that I've found;
- quite often when the screen is asleep, when I press the power button to wake it the screen doesn't come back; I get the bottom capacitive buttons lighting up, but no screen. Hitting power again turns off the lights, sometimes I can toggle it on and off a few times and it comes back (combined with swiping the screen possibly), but other times no matter what I do I can't get it to wake the screen and I have to resort to pulling the battery. Also doesn't help to plug in power. NB: yes battery is always at least 60% charged minimum
- other times when the screen is on the brightness/display goes into a build-up loop and washes out the screen, sometimes strobing, sometimes only leaving streaks of colour. Sometimes toggling the screen on and off via the power button works, sometimes it doesn't. I use Auto-brightness, but I have experimented with full- and half-brightness and it hasn't made a difference, so doesn't seem to be sensor-related.
I thought I'd hold out to see if the OTA JB update fixed it, but it doesn't look like that's going to appear here anytime soon.
Any thoughts? I've kept it relatively stock.
A small video ? Its a hardware fault anyways. Did it fell down ?

I'd post a video, but it always seems to happen when I don't have another device handy.
It hasn't had any bad knocks, only ever typical day-to-day bumps; I'm very careful with my phones. Does it sound like a specific known hardware fault?
Stock ROM, recovery, etc? Or any custom one?
Completely stock, not rooted, only some apps and widgets added, nothing removed.
Is the phone on warranty? Maybe it's hardware stuff and it will cost more than one headache.

Definitely hardware. Claim warranty asap.

Here's an example photo of one of the many exciting things the screen randomly does. I'm trying to compile a pile of photos and hopefully video to support my claim, problem is that it's so completely random. I took it to an Optus store the other day to get some sort of idea as to what would happen, and the guy seemed to reckon that they'd do what he tried; pressed the power button on/off about 20 times, if they don't get it to misbehave in that time they'll say it's not faulty!
Want to make sure I get a full backup before sending it in also.
This greeted me on waking it. Sometimes this kind of thing will randomly crop up when in the middle of using it, other times power button won't wake screen, others I get incoming calls but no screen so can't answer - power button is the only thing that responds, which of course hangs up.
I have the AT&T H900 V10 and I can't figure out how to keep the second screen from dimming when the main screen is off. It's so dim that I can't see it unless it's directory in front of my face, and no buttons seem to brighten it without during the main screen on. Is this something that can be changed? I'm not worried about battery life since it stays plugged in 99% of the time.

So far there doesnt seem to be any way to control this, other than covering the light sensor until the second screen goes off, then letting it come back on at greater brightness for 3 seconds or so until it dims again. Maybe LG is trying to make sure it doesn't drain battery but maybe they will adjust it with updates or give us control over it.
It pretty much makes the second screen useless as I can't see any notification without turning on the main screen.... and no LED light so this kind of makes me want to rage.
While running for the train today, my trusty OPO decided to wiggle out of my pocket and fall onto the road. Didn't realise until I was halfway across the street, turned around and saw my phone on the road getting run over by another car. Screen is smashed in as expected, no display etc. Fortunately, after further testing, phone seems to be still alive, as it still rings when receiving notifications and calls. Power button seems to be working given the fact that if I hold it for long enough, I can feel it vibrate and see the backlight briefly illuminate, indicating that the phone is restarting. Volume buttons on the other hand, seem much less responsive, requiring significant pressure to activate, but still work to some extent.
These are the only signs of life that are coming from the phone. From this description, I would say that the phone is pretty much fully functional, however, there are certain things that are bothering me right now. The notification light is occasionally blinking red, which from my experience is something that only happens when the phone is low battery, which I am pretty sure is not the case here. Also, I can only see the backlight light up for the brief moment that the phone is restarted. The backlight does not light up at all if I just press the power button to wake the phone up from sleep.
As a poor uni student, I would much prefer it if I could keep the phone and just replace the screen, but if the blinking red notification light and unresponsive backlight is anything serious, please advise on what I should do.
Is it detected if you hook it up to a PC? Considering the age of the phone I would not throw good money after bad. I loved mine, but got a deal from my ISP for an S7 and gave it to my girlfriend who still has it. It's a great phone, but if you suspect anything besides the screen it might not be worth fixing. Take it to a shop and let them look at it. Parts might be difficult to come by as well. It wouldn't hurt to give OnePlus a call, they might be able to help you out.
Yes it is detected, everything seems fine apart from the blinking red notification light and its inability to wake the screen from sleep.
As for bringing it in to a shop, I must say that it would be almost impossible to find a shop that has heard of the OPO, given that it was never officially sold in Australia. Repairing the screen will be my own DIY job.
My phone was working fine when I went to bed last night. I laid it on my night stand and this morning I noticed I couldn't get the screen to light up. The blue LED was blinking like I had messages. The Menu and Back buttons light up when I press them, and I can even hear when someone is calling me, but because the screen will not light up, I can't answer. The phone screen is in near perfect condition, not a scratch or crack on it and I also have a cheap protective screen over it.
Hoping it was just a glitch, I removed the battery and held the power button for about 45 seconds and powered it back on. Same thing, black screen during the entire boot process, no logos or anything. I also tried to boot it in safe mode with same results. There is only one time that the screen shows any signs of life and it only happens when I first power it on. In the top left corner for a split second, where the usual "Bootloader is unlocked" message appears, it displays a small rectangle of colored artifacts inside that small message area.
I assume the LCD went out, but I'm concerned it could also be related to the GPU or other hardware, and so don't want to spend a lot of money buying a LCD if it's something else. I can still connect it to the PC, so I'm hoping someone knows how I can test the hardware from the PC, or at least recommend something. Right now the phone is ringing and I have no idea who it is...this sucks!
