[Q] Lock button doesnt always work - Captivate Q&A, Help & Troubleshooting

I have a Galaxy S i896 (Rogers captivate model), been running CM9 on it for quite some time now and I never had a problem with it.
Until recently, my lock button stopped working. Thankfully, CM9 allows me to use the volume buttons to turn on the screen, and I can lock the device from the notification bar. However, I sometimes get that screen that pops up when you long press the power button (airplane mode, screen shot, reboot etc...) but I don't know how. Also, whenever I remove and re-insert my battery, the phone turns on by itself! So it would seem that the button is stuck somehow, and once the phone is turned on, it is being ignored.
I read somewhere that this is sometimes caused by rooting the phone, however I wasn't completely sure about how true this information was, and therefore my question is: does anybody know what causes this, and how can I fix it!
Thanks!

I also have this problem with a stock ROM. The power button doesn't work and i cant even flash another ROM in recovery because of that. It only turns on when putting the charger on or replacing the battery (turns on by itself).

It seems that your power button is busted. I had the same problem, though I manage to have a way to make things alright. If youre on a CM9/C10 youre good. Download button remapper at remap the capacitive search button and make it act as a power button. So, if you're waking up the phone you will use the volume rockers and if you want to sleep and lock, use the search soft key.

Htc Tytn 2 Screen problem

Hi everyone,
I got a HTC Tytn 2 and i have a problem with it.
When i boot the phone it starts up and goes into windows like every windows mobile phone.
But when i press the standby button my screen wont go out of standby.
Only when i reset the phone it will work again.
Anyone got idea's ?
Oke, since no one responded.
Is there any way how i can make the Power Button replaced with the Speed Dial Button.
Because i think my power button is broke.

Have you at least tried backing up your data and doing a hard reset first ?
Yes, and i have also tried to put on a new rom and even updated the radio.
Iam a little bit out of idea's...
here are some more ideas:
1. how to test the power button: you say pressing the power button does not wake up the device once it goes to sleep. conversely, does pressing the power button put the device to sleep while the screen is on? if the power button is unable to make the device go off->on as well as on->off, then the power button is likely broken. if pressing the button achieves on->off, then the power button is probably ok and some software issue becomes more likely.
2. how to enable wake on pressing ANY hardware button: look for an option in Settings. i can't tell you the exact option because the ROM i am using does not have a link for this option, but this option does exist 100% in stock ROM and in lots of other ROMs. it contains settings like "Lock all buttons except power button" and "Keep all buttons unlocked" or something similar. by using the second option, pressing ANY hardware button while the screen is off will wake up the device.
3. you can use AE button plus to perform even more advanced button (re)mappings.
4. just to be sure that your device is really working correct, does the screen wake up when you call the phone or when you receive a text message? if it does not wake up even then, then search for "sleep of death".
Thanks for the response.
I think its a Service of Death problem.
Because when i try calling/smsing it, it wont go on
The buttons do work then...hopefully there's a fix for this problem...
Oke, i tried switching to 2G or 3G only but that didn't fix my Standby of Death.
I also bought a new sim card of vodafone so i wont get a No Sim error.
But what can i do now about it...it hangs like every 5 min...
Okay, after a will testing, the phone hangs every time its almost like when iam on the road with my tytn 2 and placing it upside down, it hangs.
But when iam putting it in the leather holder it doesn't hang.
Any had the same problems ?

Maybe it's hardware and something is coming loose

touch screen "turn on"...instead of side button...

is there any possible way to be able to touch the screen and return its from the timed out backlight insted of the power button then the actual unlocking....
Not sure about touching screen, but there's an app called NoLock that will make it so there's no lockscreen and hitting the power button unlocks it. Eats battery though.

Is there any way? Probably. Is it a good idea? Probably not. Just having the screen up to your thigh in your pocket would be enough to turn the screen on and thus drain your battery.
Not just drain your battery, but imagine calling people unexpectedly, random texting, somehow enabling options and selecting factory reset . There's a reason why there's a lock/unlock button.
Being a lefty, I wish you could turn the screen on using the volume buttons instead.

I can. Hold them for a second and the screen should turn on when you release them. If it doesn't let me know I'd like to investigate further.

Nope, not working. It turns it on using NoLock but then that just changes the volume too.
Im running Darkys 7 btw.

Holding the volume button does not turn on the screen, you probably touched the power button with you middle finger which holding the volume button with your thumb.
Widget Locker
Try the app WidgetLocker--it's a couple bucks but lets you turn on the screen with the volume buttons if you want (any hardware button). It will also let you customize your lockscreen with widgets and unlock the screen using the soft keys at the bottom if you so desire.
Mentioned this app in previous threads, should really start getting a cut from the developer.

You really should believe people when they say something works. Just because your rom works one way doesn't mean anything about everyone else.
Now if someone would give me a link to the roms which don't unlock due to the volume buttons, I might be able to fix that.
lmao love the music

I am not using a custom ROM. Maybe some custom ROM has that feature added but it definitely does not work on stock AT&T ROM.
Works on stock 2.2 Froyo leak ROM

That's not a stock ROM by any means.
I wish the volume buttons were lower on the case. I have a tendency to squeeze them with my finger when pressing the power button one-handed.

[Q] Turning on the phone without using Power button.

Hi, everyone!
Recently, I installed CyanogenMod 7 which is probably the reason of damaged Power button. I've been keeping it pressed for a long time with X/camera/volume up etc. Anyways, I've been using it for nearly a year now, so.. I still have warranty, but it's not the case. Since I don't want to send it back yet, I come up with this question.
How to power on my Milestone WITHOUT using power button whatsoever? Even entering bootloader mode requires me to press it. Any ideas?
Even impractical ones, I don't turn it off very often, but I need to know that in case of emergency..
tried plugging it into a wall charger while its off? it always boots up my droid automatically
Sent from my Droid using Tapatalk
Oh, thank you. As far as I remember, it happened to me several times, but mosstly - there is just waving battery icon.. thanks for response though!
Additionally, how to lock screen without using Power button?-.- or access sound/flight mode/turn off menu?
cm7 has status bar toggles for all of that, if you still have it installed. dont know if theres any way to access the regular phone options menu without using the power button though, sorry
Sent from my Droid using Tapatalk
Well, I turned on status bar widgets and Locking widget too, but.. it apparently disables auto-locking screen, instead of locking on demand..
The go to sleep status bar widget in cm7 interface settings. That's the one that shuts off the screen and locks the phone. Tried it myself before posting.

Geez.
I apologize for caused confusion, I didn't notice it at first... I set my volume up/down as waking buttons and widget for going to sleep
Awesome support, splashattack, thank you very much!
I am having same problem.
I connect my cell to my laptop and it starts. I am using custom ROM.
I want to rollback to stock, so that I can avail warranty on it.
Any idea how to enter bootloader mode without power button
I tried terminal emulator
su
reboot recovery
Click to expand...
Click to collapse
But it reboots to OR not to bootloader.
Any solution for bootloader ? or any command?
EDIT
Its solved. I have assigned volume rocker for screen unlock,
I rebooted it using terminal emulator, Pressed and hold volume rocker + Dpad - up and I entered bootloader.
i am always thinking that a button at the front would have been great in order to unlock the phone easier....

I don't know what ROM you're running, but MIUI has the option to do what you're asking. It's in the settings menu (I believe under Lockscreen).
oh, ROM CM7 have it also, but I want separate app. Do you know any apps ?

Fix Broken Power Button by Destil
I found this..
market.android.com/details?id=cz.destil.fixbrokenpb&hl=en
When I tried to download it said it wasn't compatible with captivate but I found the .apk and it ended up working. I attached the .apk I was using to this post.
Another thought, I took my phone apart and cleaned it. I took everything apart down to the motherboard and I poured a little rubbing alcohol on the actual button and pressed it a bunch of times (no battery in of course) and after it dried out it seemed to help get it working again.
Also, when I started having problems again I installed a different kernel and that seemed to help as well. Who knows.. but it has been working ever since.
The Fix Broken Power Button by Destil .apk is below
Thank you topiratiko, I was about to go crazy worrying about not being unable to turn my screen on. But what will I do if the phone shuts off? How will I turn it on? My power button seems to be unable to work.

You can allways go into download mode and flash a kernel for ex and check reboot so it'll boot up, or even better use a jig by inserting it for just a bit to power on and to avoid download mode.

[Q] Power Button Not working. Plz help

Okay so my power button just randomly stopped working after some random time. it doesnt work ANYWHERE. to lock my screen, to unlcok my screen, in recovery mode i cant press anything cuase it doesnt WORK. i no its a hardware issue becuase of this. i did google this but found nothing. what can i do to fix it.
i tried a battery pull and putting it back and going to recovery to factory reset but as soon as i put my battery in my phone starts up. i can enter recovery but the power button doesnt work so i cant press anything.
my warranty is over by a long shot ( had it since it released) so cant return it.
any help would be appreciated. all i need is a way to turn my phone on and off nothing about the recovery and stuff. but if you do find someting for it that would be even more amazing.
and has this happened to anyone else, just wondering is all if this is common or rare.
thnx in advance.
it has happened to many captivates. search 'captivate power button' on xda.
What ROM are you running on your phone?
Answer to that question has a lot to do with your next steps for software workaround.
One approach; you could read up on ways to clean the power button and see if that works. Or send it off to mobiletechvideos.com and he will fix it for a reasonable fee.

i am running Aocp 5 android 4.2.1
hve been running it for a few weeks now and no problem till now
Okay, start by seeing if you can clean the power button, that may fix it for now. Again, search 'captivate power button' to find some threads about ways to clean it.
With the ROM you are running, I believe you have a version of CWM that allows to use the Cappy's dedicated menu keys, menu, home, back and search, to navigate and select recovery items.
Assuming your power key is stuck on, remove the battery, hold the up and down volume buttons and reinsert the battery to get into recovery. This will allow you to test keys, wipe, and any other function in CWM.
With the phone on and fully booted into JB, go find volume rocker wake in the system setting options and make sure it is active. Hitting the up/down key will wake the screen when it sleeps. Add the sleep/lock toggle to your notification bar menu and you have a way to instantly lock the screen without the power key.
If you still have a bad power button stuck in on position, then you will need to take out the battery to turn it off.
Hope this helps.

This is happening because your power button is stuck in the on position. Did you try to clean it as suggested earlier.
BWolf56, I'm not aware of an app or ROM that completely prevents power up on insertion of battery when the power button is stuck on. If there is such an app, I'd like to hear about it. I think maybe the power switch goes to the broadcom power management chip, so I don't understand how the app could work unless the phone never came on at all. SOD symptoms would be the result.

I had a very similar problem with my Epic 4G Touch (Sprint S2) - my phone would randomly reboot, and it kept getting worse and worse. Thought it was the ROM, the overclock, etc. I flashed back to (almost) stock, went back to original clock speeds. Eventually, I noticed that even brushing past the power button would wake the screen, and about 10 seconds later the phone would reboot.
Long story short, I bought a replacement power switch, soldered it in place, and have had zero problems since!
Several eBay sellers offer the switch you'll need.
(They don't include the skills needed to solder it in place. It's a tiny switch - about 4mm x 2mm x 1.5mm, and you'll need a good quality fine-tipped soldering iron and a steady hand. Do you have a friend who's good at soldering?)

well thanks for the reply, but i dont need it anymore. my friend conveniently had a GNex (old) and gave it to me as a present. so i dont use my captivate that much anymore.
