[Q] Software fix for power button issue I'm having?

Okay, so I am having issues with my power button, mainly because when I go to put my phone to sleep or wake up, it very oftenly pushes the button twice, thus I sometimes have to push it several times to get it to turn the screen off or on.
My question thus being (the reason I put this in the developer forum) is there a way to fix it via putting a delay on how often the button recognizes being pushed?
Pretty much putting a 100ms delay on each press so it can't wake up and put it self back to sleep in a split second.
And if this IS possible, is it possible without needing a custom ROM? or could I put in a fix via temp-root and push it through with ADB?

Man I thought I was the only one with this problem, thank god im not it wasnt a biggie, but it starts to get annoying after a while :/

Yeah, it seems like it would be an easy software fix. But no1 has address the issue that I've seen D:

sometimes i have problem also, issue cant be replicated but it happens....

I don't know. I just pushed my power button several times in a row and I don't see a problem. Never had since day one. Could be the way you're holding it. The button is kinda back a little compared to other devices.

Thats the crazy part, when you realize it happens, you try to replicate it and it works flawlessly, but if you happen to be just using the phone and you click the button it sometimes skips randomly.

I can actually replicate it, mine must be really sensitive. And yes, I have tried holding it many ways. I see it most often when its on my desk and I'm using it tho. but its not uncommon at all for me.
It wouldn't bother me if it wasn't all the time, but its pretty much every other time for me :[

Never had the problem until few days ago, and it's starting to happen quite often now. I'm a little bit worry being a hardware problem rather than a software problem.

Well? Whatever problem, just remember, you have 1yr warranty

I think it wouldn't be so much of a problem if we had trackpad wake embedded already, but if ur using visionary isn't there some trackpad wake/or maybe trackball wake for the nexus that will work?

Well I am sure its a hardware problem that can be fixed with software. If the hardware is sending multiple presses then software can compensate and tell it to only actually register lock presses once every few milliseconds.
My question is it possible to do it with a minor tweak to the code?

TMo already has a replacement in the mail for me because of this exact reason...The guy said I was the only person who said something like this was happening. Guess he was wrong, seeing other people with this issue makes me happy.

Yeah, I did the same thing. However, if my new one can't overclock to 1.42ghz at least, I will probably ask for another one
I want my G2 more future proof.

I'm glad I'm not the only one. Too bad no1 knows if this can be fixed in software.

I believe this issue is with people who did the temp root and OC'ed it to 1.42ghz. I noticed when I press power to unlock the screen, the screen will not light up right away, than it does for a faint second and shuts back off. I have to press the power button again and the unlock screen shows up. I hope this does not cause any other issues with the phone. Otherwise ill have to leave it at the stock speed.

I have had this issue since I got the phone, so it's not anything to do with overclocking.

Fascinate problem

My fascinate has started doing something strange. I can open an app and use it for a couple of minutes and the keyboard will suddenly appear then usually the app will close. Sometimes I can hit the back button and the app will stay running but usually the app will close. It does this on mainly resource hungry apps like XDA or Market though it has done it on about all of the apps. I thought I had a rom or kernel issue but I've gone all the way back to stock and it still does it. I'm beginning to think I've got a touchscreen problem but I don't know for sure. The phone is still under warranty but I want to be sure its not the way I've got something set or an app problem. It just did it on the home screen, keyboard popped up and I hit the back button and it went away. Ever heard of this?

I have a touchscreen problem as well(I think), but please try to post questions in the Q&A section. Just sayin'

had the same problem, took it into verizon, told them I was having that issue and the missed call issue and they sent me a new phone. New phone not having any problems yet (fingers crossed)

I just ordered my second replacement due to "phantom" button presses. But mine was always mimicking the home, back, or menu key. Wouldn't even have to be touching the phone when it happened.
You may be having a similar issue. although I'm not sure how you'd get the keyboard from the home screen unless your cursor is in google search our something.
Anyway, I've read of similar issues on fascinate, charge, and original droid. All required new hardware. Most commonly blamed on 3rd party chargers and possibly buggy charging code. Ends up damaging the touchscreen over time.

Interesting about chargers. I sometimes use a non-samsung charger that came with an LG phone. I'll stop using it just in case. Mine also will act up without me even touching the phone. I just got a replacement in the last 10 minutes and will see how things go. Thanks for the replies.

I have phantom button presses, too, but I've ALWAYS used my stock charger. I did notice that removing my otter box case helped cut back on

It took me forever to figure out why i could not get odin to detect my phone or why my phone would never show up as being USB connected. I was using an LG USB charging cable. I bought a new microUSB cable and it worked like a charm. I swear those LG cables are about as reliable as their phones (see LG Voyager)

Sketchy Power Button

I just used a case for a few days and thought the case was acting funny with the power button, but now that I removed it the button is kind of depressed and not as responsive as usual. It's not a huge deal, but something that bugs with such ”high quality” electronics.
Anyone else notice this? And has anyone talked to tmobile or htc with any luck? Thanks.
And I'm on the app and looked through the topics trying to find something like this, I apologize if this is a repeat.

The same thing happened to me about a month after I got the phone because my friend was a bit too rough with. Same has happened to like 1 or 2 other people I know with the phone as well. None of us have ever used a case btw, so I doubt that was the cause of it.
The MT4G just seems to have a sensitive power button. One of my friends told me his jammed at one point too, and all I could do was tell him to shove a card into the little gap and unjam it. Once it gets messed up it seems to stay slightly depressed all the time too, never to the point that it activates on its own(at least not for me), but it definitely isn't as responsive.

Yea, it seemed it was coincidence it happened after I used a case. Have you or anyone you know tried to get a replacement due to it? I assume they'd just tell us we should've been easier on our phone, even if we were easy with it.
Sent from my HTC Glacier using XDA App

Had the same problem with my MT4G I got off eBay. Not even 48 hours of having it, the power button went on me (due to repeated power cycling trying to root it). I called HTC about the problem and I sent it in under warranty.
They say that if you've modded it in any way (rooting included) it voids the warranty but I sent in my phone rooted and they sent it back (upgraded to GB) with a 1-day turnaround. I've read people who sent in their phones with CM7 got theirs back.
I try to not use the power button at all now. To put the phone to sleep I use a software app lock and to wake I push the optical pad. Once someone figures out a root for GB, I'll probably re-map the genius button to wake and sleep.

Unfortunately power button issues are pretty common with the mytouch 4g samething happened to me like 3 mytouches ago lol um u can simply call tmobile n get a warranty exchange for that if your still under warranty thats what i did i had actually called cause i had the bad screen which apperantly isnt reason enough for them to change the phone but as soon as i mentioned the power button issue the sent a new phone right away. the one i have now ive had for quite some time and i havent had any issues with it. thats a hardware issue mostly so not much u can do with a factory reset or anything another option is to just use the trackball wake for turning phone on n off frequent and use power button only for powering phone on in off usually what i do . hope this helps

Looks like my N1 has given up the ghost

Whelp. My power button has been flaky for a very long time and I've thankfully had it running CM so was able to do trackball wake.
This morning my trackball went green and stayed that way, well... until it went orange, red, and then absolutely crazy. Obviously, tried removing the battery and now am unable to power back on.
When it was powered on, it wasn't able to connect to the computer but did charge. At the moment it's off and is charging from the computer but the trackball is changing colour rapidly and Windows keeps finding a new device etc..
I guess this is time to get a new phone
Edit: HAHA! I did the jumpstart trick and my phone booted! The trackball has turned off now, though it did that earlier and it came back so we shall see!
Edit: Okay that didn't last, it's blinking red and no now its off again arghhh
Edit: Well, the lights haven't come on again since yesterday afternoon and it's running perfectly again. I guess I'm not going to get an upgrade now!

Did you do anything new to it recently?

I did not, but my son got his grubby mitts on it and dropped it on the ground so it's possible that did it, or perhaps he did drop it in water (Don't think he did but we may never know!)
The good news is, I have gone out and bought a Nexus S for £200 from carphone warehouse, so have a phone I can rely upon and can send my N1 in for repairs
Then I don't know... use the N1 for a web server or something?

I use my spare n1 as a mini web server... works great actually. Uses pretty much 0 power and is perfect for hosting files you may need while put and about.

The jumpstart method takes a while for me, and doesn't really work by removing/inserting before charging LED comes back on. One (possible) method to the madness I've seen is rapidly inserting and removing the battery, till eventually, the alternate green/orange blinker is blinking regardless of whether the battery is inserted or not. Removing and reinserting quickly once this happens powers it back on.
However, even if you are out of warranty, I recommend you return to the service center. Self-replacement of the I/O board costs about the same ~$35 for the board, so you might as well pay for professional service. Will GREATLY enhance your resale value too!
I had to have out of country service (I'm based in India), and all they charged me were the 'out-of-country' charges, and even though the N1 was never sold in India, they keep the part here. Mine was fixed within 18hrs from submitting it to the official service center here. Cost me Rs. 1350 (out of country device charges in India).

I have noticed that you can adb reboot a phone while it's charging.
Try it.

Nope, doesn't work on the N1 (not mine, at least). Neither does fastboot. Believe me, if that worked, I wouldn't have bothered getting the power button replaced! It was a terrible ordeal, having no power button and a VERY unstable ICS ROM. Every time it powered off/froze, I spent 20 minutes willing it to turn on!

Lol that sounds terrible! Maybe it's just the newer phones like my glacier and sensation that actually charge in recovery mode.
I just know that when powered off they respond to adb. Did you try it already, just to humor me?

I had tried a while ago, when my power button died on me. I did again, after reading your post. No go. The N1 is well and truly OFF when it's powered off! Checked adb devices and fastboot devices just to be sure. Nope, nothing. Device doesn't show up. Not even in recovery mode.

Shift touchscreen issue.

I noticed tonight that my touchscreen stops working when I slide the keyboard all the way out. It looks like when you slide it, when it gets about 1/2 way, the lights under the touch keys (home, search, etc) turn off, then 3/4 of the way out, they come back on, but you can't touch anything on the screen. No scrolling, no selecting, nothing. When you start to close it, the lights turn off 3/4 of the way open, then 1/2 the way open they turn on and the touch screen starts working again.
I've been watching videos on how to replace the digitizer and they look easy enough for me to do, but is it really the digitizer if it is working when the phone is closed? This sounds more like a loose cable, eight? Anyone else have this happen?

That does sound more like the flex cable

Sounds like it's most likely the Flex Cable. Which is easy enough to change. They usually don't just come loose. Has been know to happen, but it's rare. You can repair it yourself, you just have to have the proper tools. If you do attempt it, be sure to take your time. You can pick the Flex Cable / Tool Kit up on Ebay, or Amazon fairly cheaply.

That's very true. There is a chance you can damage, or even "Brick" the device if you don't know what your doing. I've changed about about five already. The first one took forever, I was so nervous. But after about the third one it was all good . Same with the digitizers, first one is like Ahhh . After about the 10th one it's not that scary. No I do not damage my phone that often. Just know a lot of people who do. That also do not have TEP Insurance.

Ok, in the immortal words of Eminem, "I'm not afraid." Or wasn't, at least. I took it apart tonight and yep, the flex cable is broken. Taking it apart made it worse and I've lost my earpiece. The good news is the touch screen works while the keyboard is slid out... But it doesn't with it in. lol
I did find some on ebay, but does anyone know of a place that sells the sliding mechanism? Mine is pretty sloppy and I'd like to fix that while I have it open to replace the cable.

Your best bet is going to be a damaged Shift. I don't know of any place that sells just the parts. But I would still hunt around on the net. Maybe check Amazon, or Craigslist.

I mean nobody disrespect I am just as intrigued by taking things apart and just as satisfied with self repair as the next tech guy, but you don't even need to have TEP to get a shift with a broken flex cable replaced. This is a warranty issue. By no fault of yours, the phone is broken. Sprint replaces these without push back, I'm on my 3rd shift. Now that you've opened it though, you may be out of luck.

You can always tell them you took it to a third party store to get looked at.

It was out of warranty. I already tried the warranty route.
Anyway, got the cable today, put it in and the jawbone connector for the LCD is jacked up. It won't go all the way in no matter what you do. So I put the old one back in and now the touch screen is completely gone.
My wife called sprint while I was messing with it cause she wanted to see if there were any repair stores that had parts and they offered me an early upgrade. $105 bucks and I get up to a $150 discount as long as I re-up for 2 years. Since I'm pretty happy with Sprint, this is probably a win-win situation for me to do it, so I did.
Now I just have to decide... Moto Photo, Nexus 4g, or Samsung Galaxy 2. Any opinions?
*edit: I use CM7 on my shift and would like to continue to use CM7, I don't NEED CM9, but the option would be nice.

Ok, didn't want to clutter things up and start a new thread so I'm gonna hijack this one. Hope thats ok.
I've been having troubles with my touch sceen the last few weeks and its very sporadic. So first issue it just simply stops responding all together. Like for instance i go to pull notification bar down and it stops part way down and i cant slide it up or down nor do the home back keys work. I have to hit power button to lock then hit power button and unlock then all is fine for awhile. And to be clear i dont have to power it off, just lock it. Another instance I'll be browsing the web and i go to scroll down it starts acting goofy. As if i got 2 fingers on the sceen trying too pinch to zoom when i clearly dont. Another silly thing happens where it acts like some one is remotely using my phone. For instance I unlock my phone and then it just hitting buttons. It's actually made a phone call for me before. Also happens when browsing or anything else.
I run miui build 112300 with sparks patch. I have ran this rom for a very long time so something tells me it aint the rom. I really dont remember what I've installed lately so don't know if an app would be causing this. Something tells me its a hardware issue but i was hoping to get some suggestions before flash something new or worse running the ruu to stock. Also, i dont think it would be the flex cable because it happens mostly without the keyboard out. Plus i rarely use my keyboard, although I'm using it right now.
Any suggestions would be appreciated.
Thanks in advance.

The first thing you can try is the latest Radio and Touchscreen Firmware HERE. If that does not work and the screen is still acting strange I would RUU back to Stock Unrooted. See if that resolves the issue. If not it's time to take it back to Sprint.

OK, thanks for the suggestions. Just flashed the new firmware. Like I said it was very sporadic so time will tell. Hopefully this works cause it's been a long time since I rooted my phone and I'd hate to unroot it.
