[Q] screen doesn't wake up while talking

I have an annoying problem with my HD Mini.
While talking on the phone the screen goes black which is normal and useful property. But my phone does not wake up, especially at darker conditions. It doesn't wake up even I press any button on the phone (stand-by button, volume button, home, back etc.)
For example, when i call someone in a dark place and the voicemail answered the phone, i couldn't hang up the phone because the screen doesn't come back and none of the buttons work. In this case, the only solution is either to remove the battery or place the phone under bright light to hang up the phone.
I've tried touch in call screen tweak but it doesn't work on my hd mini.

Can somebody please help me???

that's normal behaviour of proximity sensor,anyway you can hang up by pushing the hard button

what you have said is one of the main problems since the telephone doesn't wake up even i press the hard buttons.

hmmm that's weird..
i read somewhere here on forum that a guy had the same problem and he just opened up the phone(not only battery cover) and cleaned the proximity sensor of dust and then everything worked as it should.
btw..i tested last night in dark to place a call in dark room,and when i put the phone away from my ear backlight was on ,so it should be on even in dark room...
p.s. be sure u didnt install any app which has option to change settings of sensor,like CHT

I will try to open up the phone and clean the proximity sensor.
But this still doesn't explain the wake-up failure even i press the hard buttons. Is there a setting about this issue which disables the hard buttons while talking?

here is the post of guy who had this problem on the same phone and he solved by cleaning the sensor

Good luck

PLEASE HELP :( Screen during phone call issue

I screwed up.
I was installing yet another new screen on my phone, and I must have damaged the sensor that dims and brightens your phone. Somehow.
The problem is everything on the phone works, except when I make a phone call. Then the screen turns off and will not turn back on unless I take the battery out. This makes me think the sensor still thinks the phone is held up to my head. None of the buttons work, no matter how much I press them or no matter how long I wait to press them.
I don't know what to replace, otherwise I could likely solve the problem on my own, but I think this issue could be solved on the software side fairly simple.
Could anyone recommend an App (or maybe a ROM.. but that limits me) that disables that stupid head detection? I can not find it in settings either.

I had a similar problem to this once but it was related to a kernel. When id take the phone away from my head the screen would stay off and not come back on until i would swipe my finger back and forth over the proximity sensor a couple times. The dev of the kernel Tiny figured out the issue and fixed it in his next release. Kind of sounds software related but hard to tell. If it does need replacing its called the "CM3602 Proximity sensor - 0.5mA by Capella Microsystems". I believe this part acts as both the proximity and light sensor. Does your screen still dim and brighten when set on auto brightness? There is an app on the market called "Proximity screen off" but i cant figure out how to get it to work, mabey you can.

I actually found a simple way to dissable it. Add the line below anywhere in your build.prop
Code:
gsm.proximity.enable=false
I verified that it does work.

I have resorted to that very same app and I can't figure out what to do with it either.
And when I make a phone call, the phone simply stays off ... forever. I can still hear voice mail and all that stuff. I need to take out the battery and power the phone back up after ANY call...
I am pretty sure I know what I did to break it, but I rather fix it software wise if someone could explain what to do. I'll fiddle with that app a little more.

Did you see my post right before your last post. You can dissable the sensor with a build.prop edit.
Use a file explorer to go to /system/build.prop and use a text editor to add the line from my post above.

I did that, it didn't work. Can it be at the very bottom of the build.prop?
edit: Tried again, it just simply disables all the buttons.
I had this issue once before and it was because I had the sensor covered with a piece of double sided tape. But this time I fear I just straight up damaged the sensor somehow while repairing the screen.
What works:
EVERYTHING!
What doesn't work:
I dial someone or they dial me and if I answer the phone, meaning I enter into a phone call, the screen goes dark and every button is disabled.
Let me try everyone now while I have it in this mode:
1. Power button
2. Volume up and down
3. home
4. menu
5. back
6. search
7. trackball
Only way to get back into home screen is to take out the battery.
Ugh, I wish I had just been more careful. If I can't fix this with software I might have to suck it up and live with this giant pain in the ass until my upgrade time

The build.prop edit worked for me, and it didnt dissable any buttons. The edit can be anywhere in the file as long as its on it own line. Did you remember to mount system r/w first, and to save the file after editing? Are you rooted and s-off?

I think so for all that. How do I double check s-off?
Also, I found a way to get the buttons to come back on after I enter a phone call or the phone call ends.
Simply plug the phone into a power charger, because that always wakes my phone up. But other than that I can't find a way and that is useless to me out in the "field".

You can see if your s-off by booting into hboot. Pull the battery reinsert and then hold volume down and power untill a white screen appears. The end of the first line should say either s-off ot s-on.

It says S-off.

Download and flash this thru recovery like you would a rom or mod. http://dinc.does-it.net/dissable_proximity.zip It should dissable it for you. The first boot may take longer than normal as it also clears the cache and dalvik-cache, so be patient.

I figured out how to use that app Proximity Screen Off, but it wont help you in your situation. What it does is allow you to turn on and off the screen by holding your finger over the proximity sensor for a configurable ammount of time. Basicly created to prevent wear on the power button. I kind of like it, especially since i think my power button is wearing out. Despite cleaning it it tends to stick sometimes.

Flashing now, I will update you once it is done <3.

It must be something else. I flashed it and it still refuses to keep the screen on and the only way I can revive it besides taking out the battery is plugging it in to get back to the lock screen....
*sigh*

That sucks. To rule out a software issue i would do a nandroid and then flash a fresh rom and see if that fixes it. If not i would say you need a new sensor.

I might check out the new ICS rom. Maybe by some miracle it will fix the issue.

I put ICS on it. Ics runs flawlessly. but the phone problem persists ....
ugh I might just get a new phone... its a damn shame. I wasn't gonna upgrade this phone till it dropped dead.

[Q] URGENT! Phone has turned it's screen off forever!

I just tried to call a friend, and then the screen has gone black. I could hear the voicemail recording, but cant do anything about it.
I've tried plugging it into the computer, charging it normally but nothing is working. I think there's been an issue with the proximity sensor at the top of the screen as there is a little red light on.
Is there anything I can do other than sending it back? Lord knows how long that will take and I havent backed up any of my phones data

Try restarting it by holding the power button for ~10 secs

Or if that doesn't work hold down the power buton and the volume down button for..5-6 seconds or so.

hey thanks for the help guys, managed to fix it in the end

hi
getting replacement phone tomorrow so was just checking forum. anyway i had the same problem but it happened way too many times after making calls. ended up contacting my provider for a new phone.
as im under 28days they will exchange it at my doorstep so i dont have to send it back or not have a phone for a few hours.
btw do not know why this happens but not noticed it on the newer update.

Call issue

everytime I make a call on my phone the screen goes blank as if the phone has turned off (the call still goes through).
after the call the screen doesnt come back on.
I have to hold the power button in to reset the phone.
I done a factory resetbut still the same issue.
Any ideas people?

it might be your proximity sensor..
Whenever you make a call and hold the phone near your ear the proximity sensor detects this low distance between your phone and you and turns the screen off (maybe to save battery) ..
it means your proximity sensor might be damaged...
I'd recommend you to download CPUZ and check if the proximity sensor is working properly by holding your hand near and from the phone.. you should get 2 values:
0 cm while holding your hand near the phone
5 cm while holding away
you can also check out the lg hidden menu by typing in dialer
3845#*975# - lg e975
3845#*970# - lg e970
in the hidden menu goto DEVICE TEST then INDIVIDUAL ITEM then KEY PRESS TEST ..
Test it by holding your hand near away as i explained above ..
if the proximity sensor is working well.. I'd recommend you to factory reset

thanks I will give that a go.
btw I have already tried a factory reset.

Hi, did you get your phone working good when making a call? I have the same problem with mine and cant figure out how to fix it.

[Q] How to fix incoming call?

Hi does anyone know how to make it so the screen turns on automatically when an incoming call comes? Right now, I have my phone on vibrate so I know an incoming call is coming, but I have to press the power button to see the screen and swipe to answer the call. Is there a way so the screen can come on automatically?
Also, is there a way to keep the screen black during the call, unless I press the power button? RIght now, when I'm talking to someone on speaker phone, the screen stays on or comes back on if I move the phone close to my face. Any suggestions are welcome.

Sounds like you have a problem with your proximity sensor...

Do you know how to fix that? I would like the screen to come on as soon as a call comes. Typically I have to wait for at least 2-3 rings.
