[Q] Strange digitizer/hardware keys problem. - HD2 General

Hi!
I had some liqiud_on_phone (eco bathroom cleaner ) problem two months ago, but I've disassembled phone, dryed by paper towel and hair dryer (on lowest setting with cold "blow") and nothing was broken. sim card and microsd card were wet by this liquid which I believe wasn't electricity conductor - phone was powered on for quite long time after that "situation".
Since one month I have problem with unlocking phone from lock screen. WinMO or Android - doesn't matter - always the same:
when I press power button touch screen doesn't responds, but when I press other hardware buttons I can unlock phone. Only after reboot there is some time where power button works ok.
Did anyone have same problem and where can I find solution for this?
OK, now I've figured it out... On 99% it is power button problem. When screen blanks itself then I can wake up phone by any button but power (power button wakes up but touchscreen doesn't work).
Please close/remove current thread.
Cheers!

[Q] Frozen screen

Hello. I accidentaly left my phone on the ground and there was juice on the ground. In the morning my phone's power button didn't work (always being pressed inside). I believe that juice flooded holes around power button, and somehow damaged it. Next day power button was working fine, BUT my phone was totally frozen. I can turn on device now normally and, then I need to enter PIN code - all the numbers, letters, volume buttons don't work, only power button is fine.
Help, please!

[Q] Milestone 2 power button repair

Hello there guys!
Recently my M2 power button stopped working, there is no click whatsoever. I checked it up and it seems that the small metal piece fell somewhere inside the phone. I found this dissasembly video : http://www.youtube.com/watch?v=BUXSmlwUC9Q
Now here is my question : it looks like while dissasembling you are ripping the phone apart, is there any permanent damage when trying to dissasemble? I could do it by myself, pasting the metal piece inside but I m a bit concerned about damaging the phone.
Thanks
Strange Milestone 2 power button problem
Hi, I have a strange problem in the power button too, but it's very rare (may be rare just for me)
The thing is that the power button suddenly stops working. If i take off the battery and put it again the phone boots without pressing the power button, and it still not working. Then after some time, it suddenly starts working perfect there is no need to press it stronger then normal.
I can't find out any patterns in this behavior. Another strange thing that happens is that sometimes the button works intermittently and delayed. Example: I do a long press of the power button and nothing happen, then the shutdown dialog shows 2 seconds after. And some times (the most) it doesn't
I'm a little bit confused about it, any ideas?
I've new info: i can't get into bootloader mode (the phone turns on but i get a black screen with no text)
Think I am getting the same power button problem now. How did your repair go?
Same problem here now, dunno if its really related to the power button or something
completely different is going to break down soon.
I will try to replace the whole flex cable with the buttons, but shipping needs some weeks.

Focus is dying, what could it be?

i suspect the power/lock button is FUBAR, but there are some other symptoms that do not resemble just a bad power/lock button. here are the symptoms that indicate it is the power/lock button:
1. when the phone is off, almost impossible to turn on. sometimes have to press and hold power button 10-12 times before it will shut on
2. when the phone is on and i press the lock button to lock the phone, most of the time it thinks i held the button and says "slide down to power off" although sometimes it doesn't respond at all. it almost NEVER locks when i press it (like it should be doing)
3. when the phone is on and i press the lock button to unlock the phone, most of the time it shuts off completely and i go back to step 1
symptom that indicates another problem not related to power/lock button:
1. if the phone is off and i press the power button, when the phone responds it will sometimes say "samsung" like it is turning on, and then nothing else will happen. i won't get the ATT screen and it won't boot up. this some times happens multiple times before the phone finally boots
currently i've been letting the phone time out automatically instead of the lock button, and using the camera button to unlock it. i've also been trying to not let it turn off at all, because getting it back on is really tough.
is there anyway i can disable the lock/power button...and/or is there an alternative way to lock and turn on your phone that doesn't require the use of that button? even if i tell myself not to use it, there are still times in your pocket where the darn thing gets pressed. for me that could mean it kills my phone and doesn't restart for the rest of the day, which i'm sure you can imagine is not ideal.

You seem to have a (hardware) problem with the power button (obviously).
There are a couple of ways to turn on the phone/display without the power button:
- camera/back
- connect power charger
- usb connect
Last 2 are not practical and first you already do. You should try and see how much would it cost to replace the power button, if you're out of warranty. Should be cheap, and beats workarounds.
is there any way to lock it rather than letting it just time out? what about turning it on?
do you feel pretty confident that the seemingly unrelated symptom where the "samsung" screen comes up and then shuts off while trying to turn the phone on STILL indicates the button is broken? just worried this problem extends further than just the button.
thanks for your help.

There's no other way to turn it on (except plugging it to charge) and you found the one workaround, with the camera.
I am *very* sure that the power button is the culprit in your case, most likely the spring that pops back the button is either broken or out of place.
If you keep the power button pressed, in 2 seconds you'll see the slide message, but if you keep it pressed, then it just turns off after 2 more seconds. So, yes, it's the power button and nothing else, in your case.
Fix that and you should be back to normal.
And you're not the only one with this problem. Recently, I've tried to help someone else here, with the same problem, as you can see here.
thanks. i called around and a guy here in town said it will take him 30 minutes for $30 to fix it. i'm taking it to him at lunch, so hopefully i'll come back with a fully functional phone--he also was pretty certain it was the power button, and had seen this before. thanks for your help.
well it wasn't the power button. apparently there is a battery connected to the power button that is dying. but you can't even order a new battery, so pretty much once it's dead, it's dead for good and you have to do the camera button workaround like i was doing.
though he did solder the battery to the board a little more (that's another problem, from the factory it is soldered to the main board so even if you could replace it, you'd likely damage the board), and it seemed to fix the problem. he claimed it would only be temporary and within a few weeks the problem will likely come back.

That is weird indeed. I don't think I ever heard of another type of battery being used in phones, tied to buttons. Unless it's a capacitor but anyways...
Thanks for sharing the info with us!
I know this is thread is almost a year old, but unfortunately, it seems my Samsung Focus (v1.3) also has the exact same issue.
The worst bit is that every other aspect of this once glorious phone still works and I was very happy using it, not really feeling the need to upgrade.
I was using a custom ROM which I flashed back to AT&T original 7004 but that did not work. It doesn't seem to be a software issue at all.
The symptoms are the same - tapping the power button to lock the phone gives you the option to slide to power-off and after a second it will do that anyway (without any interaction). When you try to boot, it won't progress past the SAMSUNG screen and in the rare chance it does boot, it will work for an hour or two before dying again. Connecting power helps a little (as you can't turn off the phone with mains power connected), but only just. I have tried using the original battery which I initially suspected was causing issues but even a generic battery has the same issues. I'm tempted to spend $20 on a genuine battery but I don't think it will really help given the generic battery did work properly when the phone was itself.
I'm now faced with upgrading to the Lumia 920 but with new models around the corner I think I'm going for the budget Lumia 520 which has similar specs to the Focus (except LED flash) and will hold out for the new flagship model, or buy the 920 when it falls a bit more.
Hi - just wanted to add my experience with this issue (as my focus exhibited these exact symptoms today). Unlike some people, though, even if my phone managed to boot up, it would shut down again after a few seconds on the tile screen.
Like cysser0, I also suspected the battery at first, but replacing the long-life I had purchased last year with the original battery (which I keep charged as a back-up) had no effect on the symptoms. To be brief, I tried all sorts of things over the course of an hour. Nearing the end of my tether, and resigning myself to try a format as a last resort, I discovered that if I held the power button and the volume button down, I could get the phone to stay on. Releasing either of these buttons would result in the phone switching off suddenly.
Wrapping a rubber band tightly around the top of the phone has allowed me to continue using the phone for the moment, and I have managed to do a backup of all my content (not that I will be able to restore it on this phone, it seems).

Broken Power Button - Super Sensitive

Hi guys, I'll go direct to the problem.
My power button is broken. I can still use it to open/close the phone and lockscreen/wake the phone up. The problem is its very sensitive. One time it went bootloop - (not bricked) like the power button was held down (even if Im not touching it). Sometimes if I just brush my finger on top of it, or tap very very gently (without it clicking), my phone would restart. There are even times when it shuts down just by me putting it down on the table.
Is there anyway I can at least disable the power button while the phone is turned on? (I can use the home button to wake, and a widget to lock).
Or is there any quick and easy way to fix the button (without requiring any technical knowledge on electronics)?
Thank you very much to whoever can help.

Either pop the button out & fix it back in again or you will need to get it replaced
Looks like I'll just have to buy another phone.
I hear something moving inside when I shake the phone.

[Q]

I recently got my G2 D802 wet in rain. It was in my Rain jacket's pocket, and got a little wet, i turned it off and cleaned it with tissue and put in a plastic bag. when i came back to home i sucked air from speakers grill and turned it on. it opened fined except touch was not working in certain areas, then I opened its back casing (its easy) and used hair drier to dry it for over 1 hour, i dint put drier too close in case phone gets too hot, but im sure i dried it well, then i turned the phone on and it worked fine, untill next day when its power button started acting weirdly. power button works fine, it turns phone off, unlocks it, only problem occurs when it doesn't turn off screen when phone is unlocked. like when screen is on. i have tried locking and unlocking in recovery TWRP and it works fine there. just having problem when phone is on. any suggestions? im on Cloudy Rom 2.1.
thanks.
PS: i just check again, when phone is locked and screen off, and i press and hold power button, it displays power off menu and also opens QUICK MEMO, so i guess when screen is unlocked , power button acts as vol up and power button?
Probably some water short circuit your buttons. A good manner of dry wet phone is:
Disconnect battery
Put the phone in rice for almost 24 hours
Reconnect battery ......Pray... And turn it on
