The previous owner has dropped my XT2000 at some point and the external (quickview) display is not turning on upon fold. The display itself is working fine, since it's active when turning the phone on, its just not being "told" by the phone to come alive. Upon further inspection, the phone doesn't even go to sleep when folded.
I assume there is only some sensor that's broken. I've tested lighting and proximity sensors on the inner foldable display side and they work fine.
If you know, can you please tell me which sensor might be in charge of turning on the external display on fold, or the sleep function?
P.S. The damage from the fall is actually minimal, just a small crack towards the bottom of the external display. The damage may not even be connected with this issue.

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.
So I figured I would post this up just in case people are going crazy about turning on their display, and then having it turn right back off on them lol. There are sensors at the top of the device by the ear speaker. When turning on the device make sure your fingers remain clear of those sensors for 1 second, if those sensors do not pick up light source by being blocked off (try it, press the power button while covering the sensors), the display will turn back off. Same thing goes for Knock on, the display wont even turn on at all. Keep your fingers clear of those sensors!
I dont think this is a design flaw I think LG inadvertently did this to keep from the device from turning on in your pocket by accidentally hitting power on knocking on while in your pocket. it might also attribute to poor knock on feature in low light areas or night time.

There's also a bug which emulates the same symptoms,while the sensor is not blocked. Changing the screen-off effect to different effect, is a work around for those caught with the issue.

Its interesting that LG went with this sensor design. This sensor thing is kinda weird seeing as people will no doubt block this sensor and trigger this effect without even realizing what they are doing, making people think their device is broken. LOL im sure this is talked about in the instruction guide but who the heck reads those things now?
Hi guys,
Recently, I was using this tablet to play a video under "Stamina mode" and all other energy saving features turned on in Settings/Power Management and discovered a phenomenon that I don't know previously.
A phenomenon was observed, the display shuts itself off at random times when and only when the device is being held up-side-down.
Turning off "Stamina mode" and this phenomenon does not reappear.
I can not think of any reason why this should occur and not when the device is held in any other orientation.
This tablet's screen can be turned on/off with a magnet in cover.
However, if the user decides to relax and use the tablet while up-side-down, I don't see the intelligent side of this in Stamina mode while device is held up-side-down.
Really, try it out on your tablet, this phenomenon is hysterical and quite annoying.
Do you use the tablet up-side-down?
And do you think this is a reasonable feature?
My device doesn't show this behavior.
yes i have noticed it i thought i was going mad.... but i have repeated it several times.. i quite often rest the tablet upside down under my nose to watch the tv then i flip it back up and the screens turned off.!! i thought i must have bumped the power switch or something, but I've repeated it several times now... very odd if is a feature. it's like flip to sleep or something...
i just had a thought maybe in stamina mode it turns this on.... flip to turn off or it's the eye ball tracking thingy when it can't see you looking at the screen it turns it off.....
just had a look in display settings its called smart back light control. but its not turned on.. so it's not that.
must just be the tilt sensor is enabled to turn the screen off when it's tilted flat on it's face..

I have experimented with this several times. It depends on whether or not the device has moved or stationary.
Since, this only happens face down, so it is annoying.
So, it's like telling you not to lying on your back to watch a Firework show using Stamina mode for example.
If you lay the device face down on a table using Stamina mode it will turn off the screen shortly after obviously to save energy.
And if it is held up-side-down it turns off the screen randomly as it detects no motion. So, the user isn't likely to continuously shake the device while looking at the device up-side-down for any reason.
Does anyone else suffer from an issue where you make a call from contacts and screen turns itself off? It's really annoying, and sometimes pressing the home button doesn't work, it turns screen on and then it goes off again...
Is this really normal behavior for the s6 edge? Anyone?
The phone turns the screen off when making a call and putting something near the proximity sensor like your hear or your hand.......
Otherwise it stays on, unless you have a very short standby display time.
It was the screen protector covering the proximity. Even though it was clear seems to still block proper functionality of the sensor. I only just figured this out... Next time I'll get one with a cut out for the sensor.

That is normal for basically any phone due to the proximity sensor. It detects when an object is near it while making a call since it will think you are holding it up to your ear and it turns itself off to save battery life. The proximity sensor is not a camera, so it does not matter if the object it detects is clear.
I have a problem. It's the Nova 5T. It was bought on the of this month and I was not able to follow the situation as it was on Android 9 / EMUI 9.1 or 10.0 because EMUI 10.1 arrived soon! It literally went uodate for an update! I don't even know how I noticed, but there is a problem with the proximity sensor. Namely, when the phone is in a horizontal position, for example on a desk, and a call is in progress, the proximity sensor does not respond, ie the phone turns on the screen regardless of the proximity sensor being covered and in that case it should keep the screen off. In a horizontal position and a little when the phone is lifted, a few millimeters, the sensor does not seem to be covered by a finger, it does not react but the screen is on, which should certainly not happen. I tried with a hard reset but everything is the same. Can you tell me, how is it with you who have this phone? I wonder, is this a possible bug in EMUI 10.1, is it a normal function in EMUI 10.1 or is the proximity sensor on the phone simply broken? In case I do the same only the other way around, then I turn the phone screen towards the floor, e.g. I cover the proximity sensor with my finger and hold the phone horizontally. The phone and sensor respond normally and the phone screen does not light up during a call. Let me note that the proximity sensor in the upright position of the phone, for example when the call takes place and the phone is on the ear, normally turns off the screen and everything is fine. The phone is not as agile as the carousel rotates in different slits, poses and angles to test its correctness, this problem was noticed quite by accident. If someone has this phone, it would be helpful for me to write if it is the same with him or if there is a problem in my phone! I would ask someone from Huawei to answer me. Sorry for my poor English. Thank you
