Hi folks:
Sorry if this problem has been covered before. I ran a search to try to see if I could find someone having this problem and could not find it. This problem started all of a sudden (without any ROM updates or nothing).
This is it: I make a phone call, and immediately after I press "TALK" on the screen, the screen turns itself off, and I don't have access to the keypad, or any of the touchscreen functionality.
I tried pressing all the hardware buttons to see if the screen would come back on, but nothing, it stays off.
Then, when I hang up the call (by pressing "END CALL" on the screen), the screen comes back on and everything is back to normal.
Can anyone offer any clues to solve this? Thanks in advance.
is the phone near something? maybe your ear?
is anything in front of aproximity sensor? (upper left, near speaker)

Nope... I use a BT headset since I got it (this only started happening 2 days ago, and I've used this device for over a month now).
It also happens everywhere (in my room, outside in the street, etc).
Very puzzling... I am thinking of doing a hard reset, but want to see if anyone has had this happen before...
Does it happen when you don't use the headset?
Yes indeed, I had already checked that and ruled out that the headset was causing the issue.
have you recently installed a "screen protector" ? This happened to mine as i hadn't quite got the holes lined up for the proximity sensors.
thanks,

This happened to me as well today. Had the phone for 3 months now and can't say I've noticed it before. I do have a screen protector which also covers the proximity sensor (no holes in that area), but this was like a month ago and I have had no problem accessing the screen during calls until today. I have made a couple of calls after the one I mentioned but didn't remember to check if the problem was still there. Will try to see on the next one
ive been able to just press a face button to bring the screen back up. of course mine turns off when i put it near my ear thats intended. i had an issue where the touchscreen would not work at all durung a call. the screen would be on but only the physical buttons could do anything. a hard reset fixed that
Yeap, coincidentally, I just installed a screen protector and a protective case (darn). I will try this without the case and report back.
Thank you !
Problem solved ..
Been trawling these forums for hours for a registry edit to fix screen blank when making a phone call - LOL - who would have thought it was the cheap plastic case I whacked on the other day!

Hi,
When i first setup my Exec using personal mode, the answer and hangup buttons on the hinge woudl illuminate when a call came in (when the unit is closed like a laptop). Now i am using it in corporate mode, the LED's don't illuminate. They only illuminate when the screen is rotated into PDA mode.
I am assuming this is a reg hack. Does anybody know what it is? or has anybody else got this problem?
Cheers

They don't illuminate when the device is closed, only when you have the screen open or facing outwards.

And very annoying it is too - especially when both buttons look so similar when not illuminated. This must be hackable?
This has got to be one of the most annoying features of the exec.
Also i have found that if the device is closed, MSVC does not recognise anything you say when activated via BT.
I have never really played with the device in personal mode as the GUI is bollox so cannot comment on if the buttons light up or not when the device is closed. But what i do know is that when it is closed the screen is switched off as if the device is in standby mode, maybe this has something to do with it.
I try to memorize the position of the green button in relation to how I always hold the phone and feel for it like a Braille board. So far I get it 75% of the time.
is anybody using the 'Personal' install on their exec? can they confirm if the LED's are illuminated or not when the phone rings when it is closed?
Cheers
Paul
Someone who's actually opened the Universal may be able to confirm this, but I suspect that the answer/hang up buttons on the hinge don't actually have LED's. I believe that they simply use the light from the screen's backlight to illuminate. As near as I can tell, they're only on when the screen backlight is on.
If that is the case, then there probably won't be a way to get them to illuminate when the case is closed, unless someone can figure out how to get the backlight to stay on when the case is closed (which would also be a big battery waster)

Yup, i can confirm this. I've just removed the cover on the top of the hinge. There is one wrapped cable coming out of the base at the right hand side. This then splits off, the main part goes up into the pivot hole, and a thinner wrapped wire brakes away from this and attaches to a small pcb which has the buttons and the LED's mounted on it.
Yes, the buttons are only illuminated when the backlight is on, but the brightness of the buttons remains constant even when the backlight brightness is turned down.
Cheers
Paul
As far as I see it, even if the backlight has to come on that wouldn't be a problem - after all, the phone is waking up in order to ring. I also often open up the screen slightly to see who's calling, then close it and press the answer button - therefore switching on the backlight initially would actually save time!
Maybe somebody knows of a "wake-on-ring" hack :lol:
I've just noticed it with my new Qtek 9000 and I was very worried, because I thought my device is broken.
But now I know this is "normal", but it's very annoying :?
I wish I had this problem! .. since yesterday my JJ seems to have those lights permanently on even when I switch the device off
Guys, I've made a program that will keep the hinge leds on all the time.
Actually this is an accidental discovery for a program I'm working on for this thread:
http://forum.xda-developers.com/viewtopic.php?t=37201&highlight=
Those guys want to be able to use the keys and phone functions with the lid closed.
I'll post more in that thread, but basically closing the lid puts the hardware keys in a special state such that they are not responsive at all until the device is woken internally (eg by an incoming phone call). Actually, can someone confirm that the hinge keys work when a call comes in but the lid is closed. I presume they must, since they don't do anything else!
So, the hinge lights are on when the screen is on. But the screen is switched off when the lid reaches about 10 degrees to closing. But the hinge lights can be kept on nevertheless
Grem: are you using TCPMP or a similar program to play music etc in the background? Anything that tries to keep the phone "on" when the lid is closed will keep the hinge lights on.

Hi vijay555
I've actually just done a complete cold re-boot and reflashed to the original i-mate factory ROM to see if that would help, then came here in search of anyone having a similar issue.
It started yesterday, i suspect I've had an internal meltdown somewhere, plugged it into sync, noticed a few minutes later it had randomly done a warm reset and appeared stuck on the blue i-mate screen, picked it up and the sucker was hotter than an AMD without a heatsink! I suspect it's warranty time for this unit
Grem, that's worrying. What were you doing at the time? What brand/operator etc is the phone? It might be worth posting batch numbers or whatever for people that have this kind of problem so we can identify if some are worse then others.
V
It's an i-mate straight from the wholesaler no particular operator. Had it a couple of months, have seen other reports on the forum here which sound perhaps similar in that they've overheated.
I use a BT headset so I dropped my phone back into the included pouch and then put it into my pockets, yet I suddenly hear key presses during a call! It seems that the proximity sensor sometimes have a problem where if I quickly take the phone away from my face and cover it again, the screen remains lit even when the sensor is covered. Is anyone else having this problem? Its even more annoying that leaving it inside the pouch would still cause this to happen!
hi,
use search button, there is lots of post in the same suject !!
to quickly reply, there is no solution of that problem today,
u can use soft like S2U2 or others to lock screen during a call

I have the same problem, the screen stays on while I am getting calls and stay off while making calls.
Hello good folks,
I would like a bit of help with sorting my phone out. As of Thursday morning (2 AM or so) my phone has a black screen. The phone switches on, the touchscreen works (I can unlock it, put it to silent, hold the power key and tap the places on screen that would normally switch it off to do just that), the volume keys work, I can receive calls, the back light works.
Everything is as it should be, but I cant see a damn thing!
I should note that this happened once before, about a month ago and a few hours later it was back to normal. Also, I have noticed over the past few months a very small black circle at the top edge of the screen, about half a centimetre in diameter.
Please help!
Kindest regards.
It's the first time I read such an issue, your screen's probably defective.
To eliminate a probable OS issue, does the bootloader appear flawlessly ?
No, nothing appears at all. The screen is completely black at all times!
Your screen is malfunctioning, I don't know what's causing it and I don't know if you can fix it yourself either.
I think you are better off sending it back, if still under warranty.
Otherwise, ... ?
This just happened to me NOW....I'm waiting hopefully it will fix itself as i hear the HD2 heals itself LOL
Replaced screen/digitizer, screen goes dark when making a call & earpiece is silent
So as the title says, I cracked my digitizer 2 weeks ago on vacation and finally got around to replacing it. Having done so, everything works great, all touches register, wifi/lte/texting, no problem. Had to make a phone call today and came upon the issue that the screen goes black and nothing will bring it back. My microphone works but my earpiece (speaker) does not. Once the other party hangs up, hitting the power button brings the screen up like it was sleeping.
As I've gathered from other threads, I'm going to have to tear it down again and make sure the proximity sensor is properly set up and check my cable connections for the earpiece.
Is there anything I should look for specifically while I'm back in there? Thanks all - I've only had it for a month and haven't had time to install a recovery...although I think I rooted it. Don't even remember! But first things first.
Hi!
I"m not the only having the problem: during a call unintended taps takes place while screen waking up is not registered during the call. So, you see, I'm not sure a proximity sensor is the reason of the problem as far as screen is kept turned off.
I have tried to reproduce the issue by fingers, but wasn't lucky.
Have you any ideas how to eliminate the problem?
I mean not-rooted official up-to-date stock firmware use case.
And, by the way, I haven't found proximity sensor calibration in service menu for A1. Is it placed somewhere into another place?
That happens to me all the time too.
Yup, me too. While in call I sometimes unknowingly turn on the flashlight and probably look like an idiot. ?
With the rn3p I would constantly end up muted. With mi a1 the problem is much less although I've noticed that numbers are still pressed. I've learned over time to switch to keypad so when something gets touched it's not the mute and at worst the other person receives some key tones.
I also have this problem a lot. I mute myself 9/10. To bypass to problem, I just lock the screen before placing it against my ear.
Yes, a simple soutions is just when you call someone, imidiately press power button to lock the screen (no password or fingerprint requred to unlock)

That's what I've been doing. That and pushing the top part of the mobile on my face just to make sure. lol
Oh and use the Feedback app and send it to xiaomi and hope they fix it on the next update.
i had this problem too, has it been fixed in the latest of updates? its a really annoying bug.
You must be doing something wrong. This issue "must" have been in all smartphone operating systems in the world, if what you are saying is the truth.
There's no way to drop the call, or press anything while you are calling someone. The proximity sensor doesn't allow turning on the screen when it's close to an object. The gyroscope also turns off the screen when you rotate the phone vertically during a call.
But all I can say is that it's not a bug, this is how is your phone knows when you are in a call, and you put your phone to your ear, or when you use your "speaker", and so the phone knows it's supposed to used it's speaker to transfer voice through the call.
Beside my poor English, try to move your phone a bit vertically before putting it close to your ear.
same problem here, also disabling ambient display... i also tested proximity sensor with some apps and it seems ok
I have that problem too from the beginning. None of the updates came up with a solution
Same here: I mute, turn on the flashlight or even open apps sometimes with my face. And thanks for the input @SmallTarzan but i know how to operate a smartphone and did not have any similar problems for the last five years. Apart from that annoying bug it's a great phone.
Wow, i dont know of this bug since i'm using custom rom from very beginning.
Try to make a call then use your hand to cover top part of the phone, screen doesn't lock??
I am having this issue too and it is really annoying
And still nobody came up with a solution???
It's easy to understand why it happens.
Proximity activates while you're in a call, but apparently the touchscreen digitizer remains working (even though the screen is off). Touching the digitizer with your ears or cheeks activates different actions while you think your screen is locked.
I can't believe how this issue is not fixed yet! That's a shame!
Same applies for the network fluctuation issues. You need to either choose 3G or 4G to avoid loosing your data connection.
Xiaomi that's more than LAME! You need to be ashamed of yourselves.
It happens to me quite often, although not always.
It's more frequent during long calls. If the call lasts for less than a minute or so, it doesn't happen.
Proximity sensor works, and screen turns off as soon as I put it at my ear.
Keyboard is off and not responding for a while. Then, all of a sudden the phone comes alive.
In my case it's not the torch. What I activate unknowingly is the handsfree loudspeaker, which can be even more embarrassing, sometimes.
Maybe it's because I am left-handed.
In an attempt to have the proximity sensor fully covered by my face, I tried to make calls by holding the phone with my right hand, but to no avail, after some time the screen wakes up regardless of everything.
Happens to me too. Although I did notice some differences regarding the position of the phone on my ear or which side of my head I put the phone on, I started pressing the power button long ago to turn the screen off. It may not be ideal, but it takes care of it.
