[Q] Black screen after Call-end. - Desire Q&A, Help & Troubleshooting

Hi,
i got my Desire rootet ( S-OFF, Clockworkmod 3.0.5, PirateRum ( based on Cyanogenmod 7 nightly )
my hboot is: 0.93.001
PVT1.
SLCD
Now.
If anyone call me, the screen goes black, normally.
If my partner ends the call, the screen wont wake up from this "sleep" mode.
If i type the power button the buttons for search and home become bright...
I think its a bug with the SLCD Screen... anyone got this problems to?

Dude,
The desire has a proximity sensor, so when you answer a call and put it by your ear, it switches off the screen.
Perhaps there is a bit of a bug in that rom, so it forgets to switch the screen back on when the call ends.
I highly doubt its a hardware issue.

Sometimes it works, sometime it dont works.
This Desire is 2 Weeks old... Very sick. but thanks

Hi,
I have exactly the same problem with my Desire SLCD, i tried to go back to stock RUU but nothing changed
If someone got a solution.

Hey Hey i have the solution!
I fixed the problem of blank screen by cleaning dust between screen and earpiece (especially at left, where is the proximity sensor).
You can clean it like me with an air duster spay or/and with a vacuum cleaner
It works well now!!!
Enjoy!!!

how to?
i am interested

guys, check pls in what type of network screen stays black 3g or gsm,
this issue is after call only or in regular use from time to time?
this is know problem on desire, there can be falutly mobo, if your screen dont react and stays black - only battery unplug helps and this happends when your phone trying to switch between network GSM to 3G/HSDPA or from 3g to gsm
was having this issue long time + self rebooting and sent by desire to repair, they replacing mobo and know everything work fine for me,
proximity senzor works good in many cases, you can download apps to test you sensors if the proximity sensor react correctly and changing values then is not broken and pro problem is elsewhere,

face this problem on my SLi9003 and no one answer my question

This worked for me…. Finally

I'm having the same problem on my Atrix HD. This fixed it. There's an Xposed module called App Settings. If you don't know what it is Google it. I looked up my phone app, dialer app and com.android.incallui in the App Setings module and selected the setting 'Show when locked'. ( you must click the little floppy disk icon to save the setting) this shows the phone and dialer ui's o er the lock screen, but still allows the proximity sensor to turn the screen off when it's to my head

Wildfire S - blank screen bug?

Is this a known bug?
When I use the power management widget and toggle the screen brightness to the lowest. Then when I go to stand-by (by clicking powerbutton or automaticly) and try to activate the phone again the screen stays black (touch buttons light up but I can't use them).
I have to take out the batterie and reboot to get the screen back...
I'm so happy to see this.
I have exactly the same problem. My Wildfire S arrived this afternoon. I used it without any problems until about 22.30, then all of a sudden it wouldn't get out of standby anymore. The only way to get it working again is indeed by removing the battery for a second.
I did a factory reset (through the general phone menu) and now the problem has disappeared, but it could come back any second.
Other people experiencing the same problem?
This is a phone bought in the Netherlands where I live by the way, the black Wildfire S.
I had the same problem.
I had my wildfire s mount to usb... and using the navigon software while driving... then suddenly went to black screen with the keys activated.
I tried to enable the screen but with no luck.
When I unplugged the usb...I push the power button... and suddenly it came back to normal.
!!
very strange.
well... I found a sort solution for this.
If you do what you said.... the only way to enable it again is to plug a usb...and unplugged it.
!!!!!
The bug starting when we enable the lowest brightness!!!!!!!
I'm having the same problem. If you don't set the brightness to the lowest, it won't happen. So, this will be consideration between stability and use duration
Just the Backlight is turned off.
I have the same problem. Use an external light source and bring light to your wildfire S and you'see it is still alive. If you are able to find your brightness settings using the flashlight, increase it and you will have your old display again... It is definetly a bug.
Hi,
so any news on this bug or whether htc is doing something about it?
Just got my WF S with the most recent software and still has this bug which is very annoying. Would be great to be able to use lower backlight for nights/less battery!!
UPDATE: using continuous lightness, I found that whenever I choose light lower than 12% it stays dark and has the bug, please HTC do something about it!!!
Has this been fixed in a custom rom or does it presist in all roms?
I had it on original and custom (CM7.2) ROMS.
Think this is general bug, too bad. or someone does NOT have this bug??
I have this bug too. But u can Try to Pull the ring in the middel, Then the Screen shoudl appear again.
I do not have this bug.

[Q] How to change default calling app. Annoying problem.

Hi guys,
When I'm calling with my Desire HD there is pause button on screen and I accidentally touch the button which causes breaks in calls. Is there any way to change the default phoning app? I've tried GO Contacts, but it changes only managing contacts app. I'm using Cyanogen Mod 7 if this is revelant.
Hmm it seems you have a problem with your proximity sensor... Is the screen turning off when you talk on the phone?
The normal behaviour is that the screen turns off (from the proximity sensor action) when you put your phone next to your ear.
If that's the case, you can either try using Proximity sensor calibrate http://forum.xda-developers.com/showthread.php?t=951858 or contact your dealer for a repair.
You can also switch off the screen with the power button after starting a call, this should lock your screen as well.
Lastly, if you really hate your current screen and you feel adventurous, you can try flashing an AOSP Rom like MIUI (but that's a long story xD)
Hope that might help.

[Q] Screen Off

Hey, stupid question for devs out there.
In my original Froyo rom the proximity sensor broke when I dropped the phone (I have tried proximity calibrator its actual hardware failure)
The most annoying thing was that when I turned the screen off during a call it would turn on again when the call connected...
screen off, call... wait to connect...connect... screen on... turn screen off.. Talk
This problem was fixed in Rcmix3D 4.0 and ARHD 6.0 (not the proximity sensor) I could turn the screen off after pressing call and it wouldn't turn on again (unless I pressed the power button)
Now I'm in cm7 the problem is back.. My question is how hard would it be to change this... I know it's a very ad hoc request.. so if someone could just point me in the right direction that would be great. Is it a hidden setting? A driver? a massive job or something I could do myself?
Just to clarify this has nothing to do with the proximity sensor itself just the software turning the screen on when the call connects. Ty
In My Guess Its Related To Hardware Problem Same thing Happened When My Friend DHD Felt In The Snow So You Should Hit Htc Center And Let The Fix it for you. You Can Also Try Sense 3.0 Roms There is A Lot, If The Problem Persists Than Its Hardware.
Hope That Helped

[Q] HTC Desire – problems with proximity sensor

Since earlier today I started experiencing problems on my HTC Desire with the proximity sensor. For those that does not know, the proximity sensor switches the screen off when you receive or make a call and places the phone against your ear. When the call is completed and you remove the phone from your ear, the screen become active again.
In my case the moment I make or receive a call, the screen gets disabled. I do not even have to put the phone against my ear. It also means that the touchscreen is disabled and all buttons are disabled which means I cannot end the call, switch on the speaker or enable the keypad. None of the buttons, even the power one works. When the call gets ended by the other party the the screen will be enabled again. The only way to get a working phone again when there is nobody on the other side to end the call is to remove the battery.
What I also find weird is where the sensor should be, top left next to the HTC logo, is nothing. Does not matter how I look at it, there is just the black strip.
I have searched to see if there is some app that can disable the proximity sensor since I do not really need it but have found nothing. So if anybody knows of an app that can disable the proximity sensor then I would appreciate the link. If you have any other suggestions, please comment below.
Can't you enable your screen by the power button?
No i can`t

I just installed CM7on my phone and the power button works.
My first suggestion would have been to test if and how the proximity sensor works, for example with this app:
play. google.com/store/apps/details?id=com.tigermonster.proxfinder
Otherwise, for just disabling the sensor there should be another app (which however requires root):
play. google.com/store/apps/details?id=com.hatcyl.android.Hardware_Disabler
(you have to remove the space in the link because as a new user I'm not allowed to post links... they don't like new users here, right?)
A bad kernel flash can cause it... flash another kernel according to the android version and rom you are using.. If cm7 and android 2.3.7 then snq- 's kernel would be nice .. if on ICS then I recommend tiamat's kernel..

[Q] Proximity Sensor Not Working In Ace 2

hi every one,
My phone proximity sensor are not working i checked in the settings it's Turn On But Still The Are Not workings,... And Even i Install os Many Times Through Odin Because Of This Problem But No use ..
Please Help me Is This A Hardware issue
There's a way to check if it's malfunctioning. Start your phone, and head to the dialer, and type *#0*#, and a screen should come up with all sorts of buttons on it. Tap "Sensor" in the middle, and you should have a screen with a spinny thing. If you hold your hand near the proximity sensor, the white background should turn green and your phone should vibrate. If it doesn't do that, your sensor may be malfunctioning. To exit it, double-tap the back button until it exits.
what rom have you?
