[Q] Black screen after Call-end.

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.

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

Touch Pro2 (Vodafone UK) - blank screen

I have a Touch Pro2 Vodafone, but unlocked, and flashed with custom 6.5 ROM and it continually has the problem of the screen going blank and not coming to life.
I have tried Energy Rhodium 29022 and another ROM but both have the problem.
I guess it might be a hardware fault, but not sure really.
Any suggestions for fixing?

task29?
Does it "always" go to the blank screen, or is it intermittent?
Also, when you say going blank and not coming back to life - does this mean when the phone is rebooting? When it's off and being turned on? What are you doing that induces this behavior? Has the phone always done this? Have you tried the stock ROM?

You could also try remapping one of your buttons as a 'Power Management' button using the keyboard configuration to see if your power button is at fault. If all else fails, try flashing the shipped Rom to see if the problem continues. Good Luck!!

Sounds like a failed light sensor. Somewhere there was an app you could install that would display the sensor reading. If it was 0 then you had a bad sensor.

I know of such a thing for Android, but does one exist for WinMo?

I want to say that there was. It wasn't the primary function of the app, but info you could get from it. It has been more than 6mo since I was fooling around with WM on the TP2.

I ran task29 before
Have tried three roms
Problem occurs e.g., today, blank screen, cannot activate, remove battery, try to turn on, get the buzzing sound which means it's turning on but still blank.
Press buttons, oops looks like I'm calling someone.
Phone still blank. Then get incoming call - it wakes up.
This happens regularly, blank and cannot wake up.
Usually charging it wakes it up.

Flash back to stock, if it's still occurring there it's probably a hardware issue. As was stated earlier, the proxy sensor is suspect for sure.

That really sounds like a bad sensor.

And the advantage to that is, if it is a bad sensor, you could always perform some surgery on your device and install a new screen & digitiser as I did on mine. I had a problem with a slightly rattly earpiece afterwards but I think it was something I did. Handily I was able to purchase a pre-built screen and digitiser as a single unit complete with ribbon cables, I just had to swap it out and reattach the various ribbon cables. Proximity sensor and LDR are all in the one unit above the screen... Which is quite useful as they're all tiny surface mounted components

If you don't want to invest money, and like android I think that FRX07.1 does not use the sensor. That build would let you use the phone as is.

Screen Sensitivity is low in some areas?

I have lower screen sensitivity in the bottom right corner where the letter L is and the Enter is. Sometimes it will take tree taps to get the letter l to show up on the screen while for everything else it works with barely touching it. Do you guys have this as well? Some people have reported this as well.
The weird thing is that when drawing, that part of the screen works just fine with finger or the s pen, its only noticeable when pressing...
Does anyone know how to calibrate the screen? It was in the setting before but now i can't find it.

I have noticed the same

I thought it was zagg HD screen protector but i guess its not. I would like to calibrate the screen but can't find this option on the Galaxy Note 2.

I think the screen protector is to blame !

I found out that it was due to the screen protector... I took it off and sensitivity is normal now

+1 with the letter "n" (but not right now for unknown reasons).
Anyone else want to remove their screen protector?

Yeah, same with mine, the letter "K" on my screen.
I think it's a defect.
Removing the screen protector obviously makes it MORE sensitive, but I still think it is a defect and had nothing to do with the screen protectors...

Wait for the update fellows. This was the case when my note 1 was released but with the updates the issue was resolved.

I also had that same problem. When i would continuously tap the L button it would just stop responding but if i go the S pen out and started to tap it with the pen it would work fine. I took it to the shop I got if from and they replaced it with one where the S pen wouldnt work properly on the bottom right side of the screen so they replaced it yet again and now i have a phone that is fine all except the notification LED is not as bright as all other note 2's i compare it with........Must say i love the phone but Samsung NEED to be more consistent with their quality control of their phones

Me too. My device different is when i swipe in portrait keyboard swipe works fine in my l and enter. Samsung must solve.

Hi guys. Same problem here.
I've noticed a lack of responsiveness on the right bottom part of the Capacitive screen on my Note II. This happes randomly when I tap on the "Menu" icon or when texting on the "Enter", "L" or "Delete" button. As said, you tap but the Note doesn't recognize the touch. It's a mess specially when writting.
Is it then a hard or soft problem? Shall it be solved with any future update or I should go and return my Note?

Did u try any other keyboard. Its the software bug.

Sounds like the proximity/light sensor in the lcd is dead.You can replace the ribbon cable with the sensor on it if you are good at repairing tech. Otherwise if you have to have it repaired it is just as cost effective to get a new to you phone. They are cheep.
There is a thread somewhere with an app which lets you see the readout from that sensor.
You could always try a hard reset, but I wouldn't bet on it fixing the issue. Only your data to loose though if you want to give it a try.

[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?
