hi guys, I have a problem, my screen keeps doing this thing where it stops working, it looks like the device has crashed, but all the buttons work fine. the touch sensors for the screen works about 30% of the time. I've just figured tho that if I twiddle the screen a little it works again. but does it again soon after.
does this sound like it needs to go back to shop for repairs? does it sound broken?
please give your replies.
I have a similar problem with the screen:
- Sometimes (once or twice a day) the Universal does not accept touch screen input.
- Then I twist the screen back and forth.
- After this touch screen works again.
How can avoid this?
BTW, is there a method to physically fix the screen in landscape?
I only use the Universal with the screen oriented in "Laptop" Mode.
I keep having this problem with almost every build I try in my TMO HD2. When holding the phone, as soon as I make a call, the screen goes black. When I end the call using the hardware button, the keypad lights come on and the screen is non responsive until I plug in the charger. Solution?
I too have this problem but not that bad.After ending the call the screen stays black for 3-4 seconds, but it is still irritating.
Well mine stays black until I insert the charger which renders any of the builds with the issue completley unusable.
this is already known problem, especialy with DesireHD build it gets worst. there is no solution yet, as I understood, but several workarounds, for example discussed in this thread

I always say it but maybe trying a different build would work?

Do you have BsB Tweaks installed? If so, this problem is caused by having the "Tap Time" tweak set to "on". I was having this issue and read about the fix somewhere (might have been here). I set "Tap Time" to "off" and.... immediate and permanent (so far, about a week) fix.

EndCall - black screen freez
same problem here... please help me !
i had installed on my hd2 DL.Desire.v4.31.44.12 and it's worked fine for a wile but now i tryed the last version of dl desire and a gingerbread build but the problem didn't disapear. I reinstalled radio that is version 2.15.50.14 but .. nothing seams to work
I need your help guys !
Sorry for my bad english.
I was curious to see if in wmo it is the same problem, but no... in wmo works fine.
it's strange that at first fresh install of dl.desire everything was ok, but now it isn't. I've reinstalled magldr but with the same results.
It doesen't work.
I think it is something with the proximity sensor, because when i turn on the speaker and the screen is on i can end the call with no problem and no freeze.
the only solution i have for now to unfreeze the screen is to plug in the charger cable in the device.
Problem Solved
I just cleaned the proximity sensor and it's working great. No freeze no black screen.
I have the same problem.

If you have the original screen protector with the 2 holes from htc, try to clean the sensors with a soft microfiber.
I didn't had this problem untill i replaced my screen protector with the htc screen protector. (the 2 little holes are exposed to dust and dirt, and when you remove the phone from your ear the sensor doesn't respond because of dirt. I think in android the voltage for sensors is a little bit lower than wmo, and that makes the sensor less responsive)
Sorry for my english.
install from android market ADW launcher....make it default home screen...try this one too..
Solution
Everything difficult-is easier)
Just clean dust on the sreen,where sensor is situated.
Sometimes I have to knock knock twice in a row to turn on the device. It works well turning off, but on half of the times it won't turn on. Gotta do it twice. Anyone else encounter this?

I do not have that issue, but I have read in a few posts that it can be dependent on where you are knocking on the screen.

I think the biggest issue is knock speed.... mine works damn near 100% when I slowed down some, and knock slower like it showes at the end of the G2 commercials....
I think it's partially related to the proximity sensor. There are times when I can't get the knock on to work at all and when I hit the power button the screen shuts right back off.
Usually a few swipes over the sensor makes it work again. Sometimes I'll go in and turn the Knock On gesture off and back on and then it seems to work great for a while too.

This is my exact problem. The phone just decides it doesn't want to wake up with knock-on...but after I press the power button, it only turns on for half a second and it's out again. I never tried swiping over the sensor, but hopefully it works because it's mighty annoying when it does it during a call!
I wonder if there's a fix for this?

this, if you are trying to do it like you did on the nokia n9 or nokia 8800 then it won't work
slow deliberate knocks are the only way
waiting on the g2 to arrive, but on my review unit, knock knock wouldn't respond correctly if i left the phone on the table, but if i picked it up, it would work nothing scientific here just an experience of one person and one prototype
I had the same issue... What fixed it is: 1. I found that the screen protector was hindering it somewhat. 2. Go to settings->display->screen-off effect-> and change it to simple. This REALLY seemed to help. Let us know!

I did notice it does seem to behave better when set to simple for the screen off animation.
My screen protector does have a cutout around the sensors. Keeping the sensor area clean enough to qualify as having OCD does seem to make it work properly the first time, every time. Maybe it's overly sensitive?
Edit: Scratch that. 30 seconds later it's behaving erratically again. Maybe it's not the fact that it's clean, but the swiping over the sensor that temporarily resolves it.
it also seems to work much better when knocking at the top of the screen where the statusbar would be.
So I ended up swapping the phone out over the weekend for a new one and now everything seems to work just fine. Seems to indicate that it's not a software problem, but rather a hardware issue with the proximity sensor.
Guys if your covering the sensors when turing the device screen on it will turn right back of on you. It's a feature LG implemented so the device wouldnt wake up in your pockets. Don't cover the sensors.
Need a little example? Grab your phone and cover the sensors and knock knock knock.You can knock till the cows come home but it will not turn on. Same thing goes for the power button but its a little delayed and will turn the screen on for half a sec and turn right back off. Practice not to do this because your phone isn't broken. There is actually a thread on this deep in the forums somewhere but its been forgotten now.

This is true however there are indications of problems with the proximity sensor as well. Some of the devices are behaving as if tree sensor is covered even when it's not.

Thanks for this.. Very insightful.. I tried it immediately LOL
I had the same issue. I have no case or screen protector on, and was not covering the sensor when trying to wake the phone. For some reason though, knocking wouldn't wake the phone, and pressing the power button would only turn the screen on for a few seconds. I want even given enough time to get past the unlock screen. I went into the store and they are sending me a replacement that should come in later this week. It doesn't happen all the time. It is much more noticeable after receiving a call though.

Definitely is dependent on the proximity sensor. If i just have my thumb on the edge of the phone by the sensor it will display this problem. Even with my finger a half to one inch above it will do this. I will be paying close attention to the proximity sensor from now on when it doesn't work. Still have a few days to return and thought i had an issue but maybe not.

sometimes its also greasy fingers, at least in my case, rarely though
As long as you tap twice the same place it's working fine. If distance between first and second tap is greater than 1 - 1.5 cm it won't work.
Got the same problem on my d802...when i left the phone on my table for 2-3min it wont wake up on first knock knock even power key wake it up for 1sec after auto turn off again....even with no screen protector....i noticed that sometimes there is a delay about 5-10sec after knock knock and screen turns on....other thing i noticed when i knock on immediently after turning off it works 100%....BUT i also noticed when i knock on after a while it turns on and i can unlock got vibration and sound of the unlock but i cant see anything. Screen looks like its off but when i look closely i can hardly see widgets and when i set effect to tv out i can see the effect by pressing the power button...when i press the power button again screen turns on like normal...i noticed sometimes on a rerboot the lg bootlogo disapears the led is working an showing all colors but the boot animation is gone like the screen is off at the bootup...dont know why after the bootup the pin lock screen is showing up normal....sorry for my english^^
Hey guys! Recently upgraded to D80220D.
I have a problem here.
When the lock screen is set to "Swipe", knock on works great! No issues at all! LED lights up and everything!
But when I set the lock screen to, the following happens:
Knock Code works good (although the LED doesn't turn on as it does when the lock screen is set to swipe) and Knock On doesn't work at all either.
I am stock, unrooted. Please help.
That is how knock code is supposed to work -__-' if you have it enabled knock on stops working... Please search as this had been mentioned in multiple threads

Thanks for you kind reply. That is, however, not the case in this youtube video I've seen here: http://www.youtube.com/watch?v=LVTd_8ubzms. Also, I did indeed search but without luck. Despite the fact that I'm new, but I know how this forum works. Thank you. -.-
If you use Knock Code, you CAN NOT turn the screen on with double tapping the screen - only unlock it directly to the home screen with Knock Code. It's not a bug, it's a feature!

I think he means that when he uses knock code the led doesn't come on but in the video it does
Hi.
Don't exactly know what happened. Phone froze. I did long press reboot and since then loudspeaker sound is distorted and none of the sensors are working (proximity,light,gyro etc). Does anyone have any ideas? I tried wiping and flashing various ROMs - same results
Same problem here. Automatic screen dimming not working, screen rotation not functioning, display keeps disabled after calls, …
I don't have much fun using this device at the moment I would appreciate if someone could help me to get rid of this problem.
