[Q] Long press power turns on the phone?

I turn my phone off a lot when I travel to save power. I've noticed that only doing a quick press turns the phone off from a cold state which is very annoying when i'm just trying to make sure my phone is off like I did in the WM days and currently do with my android device. I'm wondering if this is restricted to my device (HTC 7 Pro) or it affects all WP7 phones.
Does this annoy anyone else? I've written to HTC so if it annoys you too please complain so we can get this changed!

My Focus requires a long press (2+ seconds) to turn the phone on. It sounds like your problem may be HTC-specific, or something is wrong with your particular phone.

Thanks for the head's up, my complaint has been forwarded to the dev department of HTC so hopefully they fix it soon.

my arrive turns in with a short press I think, as well as my tp2 and other HTC phones I've had. doesnt really seem like a big issue to be concerned over. the accidental turn off issue was resolved in the mango beta and powering off really isn't necessary just a switch to airplane mode or enabling battery saver.

Unless I misread the OP, his concern isn't with accidentally turning off the phone, but accidentally turning it on, since it seems that accidentally bumping the power button on an HTC phone will turn it on.

and I've told him that it's not necessary to do that in wp7. I don't get people, first they were complaining about the power button being too hard to press now it's the other way around.

l find that if you wanna check your phone..rather than pressing the power button press the camera button. If its on it'll go to the camera app. If its off it'll stay off.

I have never complained about the power button being too hard, I just checked and my TP2 does this too which is annoying. It's really not a difficult thing to implement and I should be able to conserve as much battery as possible without having to resort to flight mode only.
For now I'll use the camera button idea (thanks!) however ironically enough I have to long press the camera button to see if it wakes up, go figure...

Q&A is that way.... ---->

Lumia 900 Camera Button not waking phone

I'm not new to windows phone, but the Camera Button is not waking up the device on my new Lumia 900. I double checked and have the exact same settings set up on my HTC Surround, which is working correctly.
Anyone else have this problem or solution?
Thanks,

Mine doesn't do it either. I just assumed it was designed that way.

It should most definitely. How long do you hold down the camera button for?

No, it is not. Microsoft is very pround of the fact that press the camera button can wake up any WP7 phone in any state (other than shutdown) and launch camera app automatically. Try hold the camera button for a few seconds.

this worked for me, i think people are just stoping halfway when they hit the focus click
EDIT: mine only works sometimes

I've tried holding it down for a few seconds, longer than my Surround. I think it's a hardware issue. However, it does work with the lock screen in place. Just not at full sleep.

You got a point. Holding the camera button down does not work for me. Press, release and press again does. I wonder if theres a setting for that

I can also confirm that it does not work every time. I have to unlock and re-lock, shut off for it to work again. Hope this is fixable in a firmware update.

If the phone has been asleep for a while, it does not work. No matter how many times I depress the camera button and no matter how long it's depressed, it does not work.
It only works if the phone has recently gone to sleep and even then I have to hit it twice sometimes. IDGAF really, doesn't matter to me....

confirmed

Ok tried rebooting, changing camera button settings and it still doesn't work. Plus with others having the same issue I'm pretty sure it's a defect. Just giving up on the issue isn't a solution so I'll contact Nokia (God knows ATT won't help) and get back here with the results.
Keep in mind this was a selling point - "Smoked by Windows"

Guys... try pressing the button all the way in with some force. It should work. Seems they designed it so it will not accidently get turned on by mistake.

Ummmm... I feel like "EPIC FAIL!!!", but that worked . Just wasn't use to that with my Surround.

I figured it out
If you press, release, press, release, then press and hold for 2-3 seconds, the camera will start up from a fully closed state.

Mine works every time. No matter how long its been asleep.

I don't have one lol

trick with that camera button wake up: push it fast and hard.
from playing with two wp phones i've owned, i think it's because of the difference between focus press (no wake) and shutter press (wake). problem is they are two stages of the same button. the phone tells the user intent apart by measuring the time from passing first stage of button press (focus) to arriving at bottom of the press (shutter). if it's shorter than a particular value, it wakes the phone. that means you have to press it firm enough to get to the bottom of the press, and fast enough to beat that timer.
if you just press it lightly, it either doesn't get to the shutter stage at all, or doesn't get there fast enough.
it's a bit dumb, because you kinda have to slam that button hard. on the other hand, you don't want to accidentally wake the phone.

Quick press seems to work. Hopefully they fix the timing so it's easier. The Samsung Focus timing was good, and worked every time.

[Q] Power Button messed up

The power button on my S3 (SGH-i747) is pretty messed up. When i'm not touching it, it decides to register a press and completely messes up everything im doing on the phone. It has such frequent reboots that i can barely boot into recovery. The only way i can actually boot is by holding the phone horizontally with the power button facing down. Is there any fix to this? I'm on CM10.1.0 so would flashing back to stock decrease the sensitivity of this button? Or is it necessary to fix at the shop?
Also i have a cracked screen, so im not sure it would be accepted under the warranty even if it's unrooted.

Hardware failure, repair it or get a new phone
nothing you can do, the flex cable that connect's the button to the board is either busted or shorted

I'm having the same issue.
There's absolutely nothing I can do? I thought maybe if I'd open up the device and tinker with it... maybe I can get it working.

Yes this is quite an annoying problem. If you're having the same problem, are you able to boot into download mode? I can't for some reason.

Something like this you don't want to boot into download mode. What if it resets while you're pushing a file? then your whole phone will be messed up.
I got mine to boot. My method is a bit unorthodox though.... i kept pressing the power button throughout the boot process up until the lock screen. Once it finally loads... i flicked the power button a few times really hard.... it seems to stay in the position but remains extremely sensitive.. as in, i dont even have to press it to turn off the screen.
sucks man... i think this is happening to a lot of power users. I'm literally one week past my warranty.

Yeah i didnt want anything to happen while anything is installing etc. I somehow got into recovery, but it shut down within a second. (thankfully the first option in cwm is reboot, so that saved me). I can't return for warranty because I'm rooted on CM10.1.0, which was why i wanted to attempt unrooting (but that seems impossible at the moment).
http://forum.xda-developers.com/showthread.php?t=1753574
That thread seems to be the solution to our problem, but i feel that if i open it up, something worse will happen. Right now, the phone boots up fine when held horizontally (but shuts down ~2min later) and i can easily backup my data.
One strange thing that i've noticed with this problem that maybe isn't right. Normally , do you have to hold down the power button to shut it off? I always used to think that a power menu would show, THEN you could select shut down, but here, it just shuts down. The power menu flashes sometimes, but shuts down anyway. This may also have me believe that something other than the power button is the problem.

if you hold the power button for 5 seconds or more , it will skip that power menu and reboot. So this still sounds like power button to me.
thanks for the link, been searching everywhere... so fckin hard to search all the S3 threads on XDA. They need to consolidate

Were you able to fix your problem with the fix in that link? I seem to be having the same problem as you.

No, I ended up buying a new phone (I was going to upgrade anyway). I took out the power button, but that wasn't the problem. In a way, it was the button under the button that was sensitive. I would have to take out the motherboard to see the exact problem.

Problem gt-p5210 tab3 10.1.

I mean, I had the tablet on my desk with battery, more than 20%, and when I wanted to use it it was apparently off, it took me 5 min for starting, pressing the off button and then the volume. Has anyone ever been happen the same thing ? It was bought on March 2014, the last 4.2.2, and it has not given me any problems so far, without rooting. Thank you

Problem when charging
I recently installed the firmware 4.4.2 from Canada and I noticed when I charge the tablet can not turn off the tablet, I mean, if I charge the table on and turn off after few seconds the tablet turns on again, this happens to any one else? :silly:

Listen I have no real answer as about what happen. But I can say this for sure. We can not take the battery out. So there is a feature to do a software battery rest.
Just like Win7, Hold the Power Button for about 5 second and It will mimic a Battery disconnect, Do not do it longer than 10 seconds is a waits of time. If you are not sure you press it correctly, release it and try again but this time look at the button.
Now here is an issue. Depending where you are Holding JUST the Power button can behave differently.
A) Holding Power button forever, starting from Home Screen
..1)Turn your TAB3 ON and swipe to be in Home screen.
..2) Lets Press Power while holding, NO Release, so that wee can see what it does.
..3) You will see it will Power OFF, Then Restart. Nothing more Happen, just wait for ever on swipe screen.
B)Holding Power button forever, starting from POWER OFF
..1) Now use the normal procedure to turn your Tab3 OFF. Let it alone. at least a minute to make sure is OFF. Just for test purpose.
..2) Lets Press Power while holding, NO Release, so that wee can see what it does.
..3) You will see it Turn On, see the Samsung Logo and Turn OFF. Black Screen for ever will follow.
So as you see, it is possible you had your table OFF when you where continuously pressing the button!. Normal Behavior.
As for Why when Off, I do not know but I seen my table freeze from time to time and and even go off.

Yes It does, charging while device is OFF. Some time it does not like to respond. In fact there are claims that 4.4.2 does not charge while off. If you have a kernel modified the you will see the BIGG Battery symbol. But still it is hard to respond.

I don't know if it is hw of sw problem is weird

Power button unresponsive

Hi all,
My power button seemed to have become very unresponsive overnight. Not sure what happened.
When clicked, the screen would not react to either switching on or off. This would continue for sometime before it starts reacting again.
Only noticed this problem today.
The phone is rooted, but no tweaks or other things done.
I would appreciate any assistance and suggestions on this. Thank you!

Tap on screen unresponsive also?

If it doesn't work itself out, try doing a hard reset on your phone if you can. (it may not work because you need to use the power button to do it) If its a software issue I'm sure re-flashing the firmware should fix it.
