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.
Rom: Olyfr sbf upgraded to 4.1.5.7 from 4.1.2.6 via OTA
Not rooted
I have not yet modified the power button.
'Cause I set up the fingerprint unlock,Im used to swiping my finger after press the power button.
after pending or standing by a while(maybe),It vibrates once after my unlocking through scanning fingerprint.But!!!! The screen is still black!!!
Meanwhile,touching the four buttons on the bottom,it still vibrates!
And waiting for seconds,Screen on~~~~~
Symptoms sound a lot like my Bell Vibrant before it died after the Froyo upgrade.
Have you tried resetting your phone yet?...
Okay,I have flash it to 4.157sbf,and temporarily nothing goes wrong
I have the same symptoms. Sometimes when I push the power button it takes 3-5 seconds or more for the screen to light up. I did a power off and on and it works better. Not sure what is causing this but it is annoying.
I've had this on.both my atrixes and it seems to.resolve itself as the phone gets older

I have had the same issue on mine. It occurs intermittently. Not always, but sometimes. And when the screen is turned off, I push the power button and nothing happens for about 3-5 seconds. Sometimes longer.
I do also have the fingerprint security feature on, though I am not sure if that that has something to do with it. However there is another problem with the fingerprint security.
Sometimes I want to check the time so I just turn on my screen and quickly turn it back off. But the screen turns right back on cuz it recognized my click as a fingerprint. However since it is too short to be recognized, it just turns my screen back on and says to try again. I try to turn the screen off again and the same thing. This also happens on occasions.
They need to make the power button better so that ways it does not recognize a screen turn off as a fingerprint swipe.
I have had similar problems. Rebooting has usually fixed them, at least for a while
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
Hi. I'm having an issue with my Verizon S5 where the screen turns on randomly, sometimes a few times a minute, for no apparent reason. Researching the issue, I found a lot of people said the reason they found was that the charge port was bent slightly and after bending it back it fixed the issue. They noticed the screen would behave when it was plugged in because all the connections were forced into their proper places by the charger. However, mine turns on and off regardless of whether or not it is plugged in. I downloaded Wakelock Detector to try to see if there were any apps forcing my screen to wake up but it only listed a couple apps and processes and, combined, they didn't come anywhere near the number of times my screen was woken up. Interestingly, the same day I noticed this problem, my home button also stopped working. It will not turn on the screen when off and it will not bring me to the home screen when the screen is on. I thought maybe it was occasionally functioning, causing my screen to turn on. However, I have never experienced the opposite issue; I have never been using my phone with the screen on and had it suddenly bring me to the home screen. Also, oddly my screen does not have this issue when I am playing music either through the speaker or via bluetooth. If I have music playing, the screen never turns on randomly. If I pause my music, the issue returns and my screen turns on randomly unless I resume my music.
The fact that it doesn't do it while playing music (either over bluetooth or through the speaker) means it must be a software issue rather than a hardware issue. The fact that my home button stopped working at the same time seems to make it seem like a hardware issue but maybe my home button not functioning and my screen turning on and off randomly are both part of the same software issue? I have attached a screenshot of my current version of Android and other details.
Thanks in advance for any help.

Generally, I'd recommend a factory reset just to make sure whether it is or not a software issue.
If the issue is not solved, return the phone.

I was able to fix the problem so I thought I might as well share. I replaced the circuit board that goes under the home button (cost about 10 bucks lol). This is not the home button and cable itself. If you disassemble the S5 to the point where you can see the motherboard, the circuit board at the bottom with the charge port, capacitive buttons, and home button contact is the one I replaced. Hope this helps others with similar issues get working in the right direction. Be very careful disassembling your S5 if you decide to try this route.
Hi,
i have tome hassle with the hard press home thing.
Sometimes its working ok sometimes it does weird things.
for instance ... if i press the button hard it some times vibrates , when i let go it vibrates again and its unlocked... thats when i think its working correctly.
but sometimes it just vibrates two times although i didnt let go ...
sometimes on homescreen i swipe the homebutton slightly to clean it a bit... not hard pressing and its vibrating. sometimes one single time sometimes two times in a row .
anyone with the same issue ?
thanks
no one ?
Check what sensitivity you have the button set at. It could be too high or low.
I have mine set in the middle and never have an issue.
i tried severeal sensitivity settings ... sometimes it gets better and sometimes worse... but for me its not satisfying
i think i have to weit for an update or so ...
I had the exact same issue with my S8. Sometimes it just works, sometimes it doesn't detect it, sometimes it registers several hard presses even though I've barely touched it (sensitivity reduced as far as it goes).
This has been driving me crazy for the past week. The hard press function was unusable because of this.
At first I thought it's a software issue (something to do with calibration maybe?). I got an update which didn't fix it. I tried resetting it which didn't work either so I sent it back to Samsung yesterday. Waiting to see what they have to say about it.
The lack of complaints about this so far made me think it's just a weird issue with my unit.
I'm having exactly the same problem and it's driving me nuts for not knowing if it's a hardware or a software problem.
I've googled around and this is the only thread so far. Seems like there are very few people with this issue.
Let me know how the repair request went.
i sent it back also
new one is coming tomorrow ... lets see... will report
I have that issue too. Dont know what to do.

Oh wow, that's really fast. I still haven't heard anything from them. Did they give any information about what's wrong (hardware/software)?
no ... i didnt sent it back to samsung.
i bought it from amazon.de and ordered a replacement.
thats faster
it will arrive today then i can sent back my first one...
same here, having issues with the home press function .
I also send it back to the shop where I bought it
I´ve send mine back to the webshop also. My mate got his s8 2 days ago and his hard press was perfect and responded smoothly all the time. So i guess it must be a hardware problem.
Will share more info when i get feedback from the repair.
Same problem here, sometimes it works, sometimes (when the device is in standby) it works only after several tries and pressure in different spots.
Can someone who has got a new device or sent it to repair report if it is better now?
Hardware issue... my replacment Works fine now
Same problem
I have this issue also. Mostly it works, but sometimes it doesn't work and the phone hesitates to come back to life. If I press the power button after hard pressing the home button or just wait 5-10 seconds, the screen will come on. Oddly, when it doesn't work (and occasionally when it does), the small vibration thing happens. I have this turned off, but sometimes when hard pressing the home button, I get the vibration, but the screen won't come on. Other times, I get the vibration and the screen will come on. Mostly I don't get the vibration and the screen comes on. Annoying.

As i said ... it seems to be a Hardware issue. Get a replacement
Mine does this often, i personally could care less for the home button function so I set the sensitivity to max and yet at times if I barely touch the home button area it acts like I have hard pressed the button.

I have the same problem maybe even worse. To me it looks like it is accumulating presses, the more times I press the button the more times it vibrates. So at the end I sometimes get 4 or more vibrations for just one press. Sometimes after I lock the screen it vibrates by itself and turns on the screen.
Looks like I'll get mine replaced ASAP.
Got the same issue once in a while.. also have a faint red glow on the screen. Considering getting it replaced but dont want to wait for a replacement.
