phone not waking up - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
I am having this weird issue with my i9100, sometimes i can't wake my phone up! Only way is to remove the battery and put it back in
I have a feeling this may be a common issue, but I just didn't know what key words i had to use to search for this specific issue. I hope it is software, and not hardware.
I currently have the old lite'ning rom installed.
this person described my situation perfectly:
"Twice I have left my phone and then when i press the power button in the side to wake the screen in it wont turn on. I first thought it had ran out of power as no matter how many times i press the power button nothing happened. But if you press the volume button you can hear the phone beep as it gets louder so it is one. The only way i can get the screen to work is to take the battery out and put it back in again?"
helpp ( when the phone goes on sleep, it ignores everything even calls

Heya, seems like a ROM/kernel issue to me (perhaps even undervolting one). Try installing the newest version od your ROM, or Kernel and make sure you have no undervolting active. Hope it helped ya.

[Q] Htc Hd2 Volume goes up by itself???

I fell asleep next to my phone one night and when i woke up and tried to wake up my phone the volume menu opened up and acted like if i was pressing the volume bar repeatedly. I turned it off and on again and once it boots into Windows the same thing, if i try to press volume down it will and it will go right back up again. The Volume rocker button is fine and not stuck. I found out though if i hold up and down before windows mobile boots up it will allow me to operate as normal but once i let go It goes back to the volume going all the way up. I have flashed different roms to no avail.
Does anyone have any ideas to what could be causing this?
I just started having the same problem with a Samsung Omnia 7. It fell into some water, let's say it was a bucket, i pulled it apart and thoroughly dried it. Seemed to work perfectly for a few hours, now the volume thing.
Our HD2's hard buttons are not invincible and I learned that the hard way. After lots of use on my phone the send, home, end, and volume down buttons stopped working. I also believe my end button is stuck on because it always boots up on its own, meaning I can't shut it down and leave it off. I have to take the battery out of it.
My advice is if you can find a way to use "soft" buttons to navigate your phone do it and save yourself the hassle of breaking the hard ones for when you need them. Good luck!

I had a few drips of water it my hd2 and a couple days later, I rebooted and after it rebooted, the volume is stuck on UP. I took it apart. I has nothing to do with the button itself as I removed the button and it's still stuck. Still no solution yet.
Hi,
Did anyone find a solution for this? I had to hard reset my HD2 couple of days ago. After the reset, I installed all the apps, one after another. The phone worked fine for a day, until this afternoon when it started acting crazy. First symptom was that when you type some numbers of the "Phone" screen to look up a contact, I was not able to delete the using the back button. Other keys like up, down, left, right too didn't work in the SMS compose screen. I restarted the phone thinking that it would resolve the issue, but worse. The volume control showed up just after the boot and the "volume up" tone was constantly going off as though I was pressing the volume-up button constantly. I tried rebooting and remove the battery, SD etc, uninstalled few programs, but to no avail.

Power button in lockscreen

I'm not sure if this is normal or just something I've messed around with. My phone keeps shutting down in my pocket because the power button is fully functional even while the phone is locked, so long pressing it turns my phone off.
I've had the phone for months but the issue came up just recently. I have WidgetLocker enabled and
Im not sure if this hass something to do with me using the "Disable Stockholms Lock Screen" option. I've already tried disabling Easy Wake and disabling WidgetLocker but nothing seems to help.
Is this normal or have I done something stupid with my device? And if it's just me being an idiot can anyone tell me how to fix this?
Im using Cognition 1.31 and the newest WidgetLocker
Sounds normal.
If the power button is pressed for ~10seconds, or something like that, the phone powers off, no matter what the opinion of the running OS about the matter is (i.e. the OS can't prevent it).
It's a hardware trigger, kind of an "emergency off" for situations where a clean shutdown isn't possible for whatever reason.
So you better see that nothing pushes on that power button while the phone is in your pocket.
Alright thank you. It is necessary to have a way to shut the phone down with an actual button but it would be better if it was two or three buttons that have to be pressed at the same time. I just can't figure out why I haven't had my phone shutting down before. Maybe the power button has loosened so it needs less force to be pushed

[Q] Power button problem

Heey i have a problem with my power button. Had this problem before but it was gone after one day. The problem is my powerbutton isnt functionaly like it has to be. It changes from time to time.
Sometimes it doesnt work at all when i push the powerbutton.
Sometimes it works slowly. And when i have pushed te button couple of times, i get a phone with screen on, off, on off etc. Like it has lag or something.
When my powerbutton wasnt working yesterday, I saw that the button was pushed the whole time. I mean when you push powerbutton and homebutton you make a screenshot. If i only pushed the homebutton it was making a screenshot.
This things change from time to time. Any one got any ideas????
Im not even sure if its my button that is failing or it has to do something with software.
btw i already tried reflashing rom and kernel with no result.
thx in advance
It's the button, not the software that is the problem. Try taking off the back cover and cleaning out whatever dirt/lint that could be under the button.
i tried that already but it doesnt seem to work. Looks like i have to go back to stock rom for warranty. Hope this is going to be possible since my powerbutton isnt working.

Solution for Random Reboots(MOTO E)

I have been playing with my MOTO E for quite a few days.
The ONE thing that kept bothering me for all these days were the Random Reboots.
After trying many thing finally I have come up with a practical solution to this problem.
I have been having random reboots with the Stock Rom as well as other Custom Roms. Usually while pressing the power button the power menu used to appear for few seconds and then without pressing anything the phone to restart, and this happened with the stock rom as well as other custom roms. I had contacted Motorola, they had asked me to boot into SAFE mode and see if the problem persisted , and it did. So I started using the trail and error method and what I found out that it's a hardware issue, or a issue with how our power button works.
SOLUTION :
So basically what I did is I replaced the power button with the Volume buttons for waking up the device, and for putting it to sleep i assigned the pull up gesture(which is usually for launching google now). I assigned the sleep function in CM11 for the pull up gesture(if you are using the stock rom you'll need to use screen lock apps which allows that function).
After applying this, I have been using my phone for about a month now, WITHOUT a single random reboot.
This is a simple yet effective solution.
Hopefully this'll help you and save you those annoying random reboots.
Can you please explain in detail ? I am using stock rom, and my phone reboots randomly few times a day.

Use "Pocket Lock" application to lock and unlock/wake your device instead of the power button and check if the problem persist...!!
Hello,
as I was going mad with the "Power Button random reboot", I discovered your helpful post. I didn't know it was possible to set the phone to wake up on volume buttons. On the other hand CM allows you to put your phone in sleep mode touching the notify bar twice.
Half a day with these settings, it seems good, Moto E has a real problem with power button, now I have to control myself not to touch it anymore !
Thanks.

[Q] Power button weirdly causing random restart. Really need help ASAP

Hello all!
My Moto E is of lately causing a very weird problem. If I press the power button more than even 1.5 to 2 seconds (yeah, I measured it), the phone restarts. This problem was persistent when I had not rooted the phone, and even now after rooting with PA 4.6 beta5 ROM, the problem has become more grave. If I keep the button pressed even for half a second more after the Power Options are displayed, the phone restarts! I tried Factory Reset, Re-Flashing the ROM, but all in vain.
This is really a grave problem for me.
Please help.
Im too facing this randomly... I guess thats a hardware problem( mayb switch)...
Same problem here... Did everything I can... But all in vain....
Me too.....it used to randomly restart...and now i think the power button is stuck inside a little...
Its already reported in Official Motorola forum by many people here. Now i use volume key to wake up phone using Gravity box and double tap statusbar to sleep...

I used to have the same problem. Later I rooted the device and installed xposed framework. Still it rebooted randomly. I had dropped the phone a little while ago due to which the power button became a little loose. Afraid of breaking the power button, I started to wake up my device using volume buttons. Use GravityBox to do so if you have xposed installed. Else you can search for an app that does the same on Play Store(although these apps suck your battery heavily). After using the volume buttons to wake up my device, I noticed that my phone no longer restarts. If your phone still restarts after following these steps, use any different way to lock the device like 'double tap on Status Bar' (like I use).
Hope I helped friend.
me too!
i have been having this problem from quite a few days; it only exists when i install a new app and then when i delete it the random reboots will stop; i believe this is a bug in the kernel which is getting triggered by an app.
hope it can get fixed via software update, possibly by lollipop.
ps: never had a problem while on clean format (with no extra apps)
