at first i want to tell djsteve my congratulations for his streakdroid 1.9.0 rom. i think it's really amazing. unfortunately now i've got a problem with the touchscreen. when i awake the phone from the standby, sometimes the screen doesn't answer to my touch. the physical buttons work, but the touchscreen is dead. it turns on, but when i touch it nothing happens. is it a problem of the rom or it phone's fault. the only way to solve the problem is to pull the battery out and restart the phone. i hope someone can help me thanks to everybody will answer my request.
I'm having the same issue with the screen becoming unresponsive during or after a call. Pulling the battery is the only known fix
I had the same problem when listening to music with the phone in my pocket. Apparently its a known fault with the phone. Something about static causing the screen to heat up and therefore making it unresponsive. My work around was to put my phone in my pocket with the screen facing outwards, instead of inwards, think the heat from my leg and the static from pocket movement froze the screen. It doesn't do it anymore, with the screen facing outwards.

I have noticed this as well, however I just updated to the 351 rom so it's not a streakdroid problem. I think it might have something to do with AndroidAssistant app I just installed.
Recalibrate
To fix this issue usually all you need to do is recalibrate the screen by holding vol up,vol down and the power button while the phone is off and then when the text on the screen appears select screen calibration and follow the instructions after it says successful calibration wait for the menu to comeback up and scroll down to power off(you may need to select it more than once) . This problem is caused by the screen being affected by heat and sometimes after updating the screen needs to be re-calibrated so it wont be affected.

I have had the Touch 3G for nearly a year now and for the last 3 months I have had this recurring problem which is fixed with a hard reset but will recur again after about 6 weeks. The symptoms are:
1. When turning on, the backlight dims just before the HTC flash screen and startup sound (when it says "Smart Mobility")
2. Touching the screen doesn't bring the backlight back on.
3. Pressing the power button doesn't turn the screen off from this dimmed state, but after pressing touching the screen will turn the backlight back on.
4. Pressing the power button again will now turn off the screen, but pressing it again won't turn the screen back on! If I call it from another phone, the vibrator goes on but it doesn't ring, the screen stays off and you can't answer the call. If you hang up on the other phone it keeps vibrating and you need to do a soft reset to stop it.
If I do a hard reset the symptoms are gone and reinstalling the exact same software doesn't cause the problems immediately but withing a month or so it happens again. All I did just prior to these problems was use TomTom a bit more than usual, but otherwise nothing different. I have used TaskManager to see if there is anything weird running in the background but it all looks fine. I have had a cursory look through the registry but also can't find anything?
Any advice would be appreciated.

Sounds like it's going all haywire. If you've had it less than a year, I'd send it in real quick. Sounds more like a hardware problem.
I don't think it is hardware as a hard reset fixes it...it just recurs down the track. I have done a hardrest and reinstalled all my apps and it is working great again but I was wondering if I should be checking somewhere in the registry for an aberrant setting. I am u using a backup image program so at least when it happen again I an restore my system more simply.
But then again, all the symptoms you mentioned point to a hardware defect. You could try to find a tweak, but like all electronic devices, it's the luck of the draw. Try emailing HTC and see what they say.
This just started yesterday but the bottom of my screen (the side where the serial port is) seems to be less responsive than normally. When I go to click to respond to a text message I find myself having to press it repeatedly. Sometimes the whole screen becomes un-responsive or if I click up top it will actually make a response at the bottom. Could this be at all due to an app or something I installed? Because normally when I put it on standby (pressing the power button once) and turn it back on it will fix it all but the unresponsive bottom section for texting only. Does this make sense to anyone why this could be happening?
Just having touch problems all together
i keep pressing the screen so many timees... even tried to restart and take the battery out. but still same problems
any help
Thanks
Try recalibrating the touch screen guys, that might help. Also if you have a screen protector on, try removing it, I found my first one got more unresponsive over time.
I dont like screen protectors for that very reason and dont use them. But where is the screen recalibration? I've looked and looked for it since this started happening. It's half way working now and really just varies. So if there is a way to calibrate I really feel like that would fix it. Thanks!!

yeah mine did that and calibration fixed it.
power it off, hold down both volume buttons and power it on, holding down all three until the menu appears.
Choose option 3 and away you go!
hth....
Haha, this completely fixed it!!! I'm so excited right now becaus I was terrified I did something to it. It works perfectly again. Thank you guys so much!!!

Hello all,
I have a problem with my HD2's touchscreen. I've had the phone for awhile now and never had any problems. I've been using android from Sd for awhie and recently switched to NAND android.
I go to bed with a working phone and when I wake up, the touchscreen doesn't work. After trying to use it all day, it occasionly works. When I receive a call or text, the screen works just fine. I am abe to use it until the screen turns off then no more. This happens for each call or text. It also works just fine at first boot(until the screen is turned off.
Thinking that this was a software problem, I tried flashing different android builds, with the EXACT same results. I then wondered if it was a problem with MAGLDER, so I flashed back to a STOCK TMOUS rom, and stock SP, radio etc.
Even after going back to COMPLETELY stock, it now does the same thing in WINMO. Works just find at first boot until screen goes off, and works when I get calls and texts.
I'm now thinking that this is a hardware/digitizer problem, it just seems weird to me that it works 100% until the screen goes off and then not at all.
Anybody have any idea's or insights?
Thanks!
i've read a few similar threads (please search for them!) that indicate one possible cause...
your buttons strips at the bottom may be messing with the touch screen connections. i remember reading in one thread that the dude found a strong relationship between use of the on/off/endcall button and touchscreen failures.
you say it works...:
1. ...until the screen powers off
2. also works when you get an sms or call
in case (1), you have to press the endcall button to "wake" the device...so maybe the button puts just enough pressure to screw up the screen.
in case (2), the device wakes up automatically, so you never pressed the button that might cause the screen to screw up.
try to narrow it down like i've described. maybe your buttons are causing the problem. good luck!
Thanks for replying!
I did see the thread you were talking about though it did not seem to match my problems. However, today as I was working and pulling my phone out, It has started to look like that is the case. As of this afternoon, as long as I press any of the buttons other then the power/end call button to turn on the screen, the tuchscreen works just fine. When waking up the screen with the power/end call button, it does not work at all.
Yesterday and this morning, it didn't matter what button I pushed to wake up the screen, it was totally unresponsive.
So it looks like using the power/end cal button presses on my digitizer and causes problems.
And it's back to not working at all when I use any of the buttons, lol. Guess it's time to start looking into a new digitizer.
I've had a problem with my E900 since I got it with regards to the screen. I was hoping Mango might fix it but it doesn't seem to have.
Sometimes if I press the power button the screen backlight comes on (i.e. screen goes from off state to powered) but there is nothing on the screen. No amount of button pressing will cause the screen to show anything.
If this happens I have to turn the device off again (backlight then goes off) and try again. Sometimes it can take 2-3 times before it turns on successfully with the lock screen.
I also have this if an incoming call attempts to wake the phone and also alarms too.
Does anyone else have this issue?
I confirm this one popping sometimes. Not that often that it becomes annoying, but nevertheless.
Did you find a solution to this problem? I am experiencing it too and it is very annoying!
I've recently inherited one as well (E900 that is).
The one I have has been dropped, the backlight powers, but no drawing on the screen.
I've disassembled and re plugged everything (bugger stripping down!) but still no luck. I've done a VolUp+Down+Cam+power hard reset, and when I plug into PC Zune says setup needs completing (so it has reformatted) but still no luck.
I cant see anything fried, and no damaged ribbons as far as I can see, any ideas?
I sold the phone a while ago, and never solved the problem. I think it's a firmware issue.

hi.
What do you mean "somethimes if I press power button"?
Is it pressed with purpose to lock the phone, press it to turn off phone (background slider shows to power off - on Mango and beyond version) or press it accidentally?
Cheers.
So, I did a phone reset. Unfortunately the issue is still present!
Sometimes when I press the power button to unlock the phone the screen is lit, but stays blank i.e. no lockscreen wallpaper, no nothing. The same happens sometimes when I get a phone call - the phone rings and vibrates, the screen is lit but stays blank.
When this happens I have to press the power button to put the phone into sleep mode and press it again to wake it up.
What I found is, when the issue occurs the screen is actually responsive. For example I can slid up and unlock the phone then I hear the unlock "pop" sound. It's just that nothing is drawn on it!
I was wondering if anyone else experienced the same behavior and found a resolution. Also I am not sure if this is a software or a hardware problem. If I could confirm it was a hardware problem I would call LG and have the phone repaired or replaced.
i have exactly the same issue as you, it gets really annoying.
i heard from someone online that the only way to resolve it is to replace the motherboard

I am pretty certain this is a hardware issue. I am calling LG tomorrow and hopefully they'll take the phone for repair/replacement.
I sent my phone for repair. Today I got it back, and guess what?!
The issue is still present! It seems, they "couldn't reproduce" or something.
What should I do now?
EDIT: If anyone is interested, here is a video I just captured which clearly demonstrates the problem. http://youtu.be/38kF9RYs_bU
I'm sending the phone back for repair tomorrow with this video attached.
Hey, might not be an issue at all, but in the video, I saw that the two times you were able to get it to go blank you had your finger on or near the proximity sensor. I wonder if there is something that could be the trigger.
Just wondering if you can duplicated it or cause it only when you have the proximity sensor blocked, or if it truely is random.
You are right, it might has something to do with the proximity/light sensor.
On the other hand, this issue occurs even on incoming calls when the phone is placed on a table, screen up and nothing around the sensor.
Today, I visited my local carrier shop and left the phone for repair again. They told me, since this is a second claim they'll run it through the process faster, so I expect to get it back next week.
Will post an update.
UPDATE: My phone was replaced. Yesterday I got a brand new unit, yeah! It was stock wp 7.0. I plugged in my sim and used the phone the whole day, no sign of blank screen issues. Last nigh I installed all the updates (total 5 I think) up to OS 7.10.8107.79, FW 1.0.16.10. Guess what?! Same issue!
I am crushed
Hello! Just bought an Optimus 7! Really good phone for the price!
But i got one problem! When im going to turn on the phone with the windows button its sometimes not responding!
Somebody else got this problem?
Yes. Happens to me all the time, but I always use the power button to turn on the screen so it doesn't bother me that much...
Sounds like a known issue.

Same here. It must be a software bug because the button is always working when the phone is unlocked.
If you still hold for a while it works
One reason for the screen not turning on is that you may be blocking the proximity sensor at the top left of the phone. The reason behind that is probably to avoid turning on the screen when the phone is e.g. in a pocket.
for me the start button for screen unlock always works, but many times screen is unlocked and all black, the systems listen to the touch input but doesnt show nothing at all....it happens very often usually when the phone is hot...
