I keep finding the backlight on my XDA II keeps turning itself off, I have to go to the backlight menu and I find the "on battery power" backlight setting is set to minimum. It does this randomly with a fully charged battery. Might have to buy a torch if it keeps this up!!! Any ideas?
I thought I had the same problem, but it turned out to be my own fault.
My XDA II would be off and I'd press the [Power] button, to turn it on ... no backlight. I discovered, quite by accident, that if you press and hold the power button, it in fact turns off the backlight.
So ... when turning it on, make sure you just press the [Power] button and DON'T linger.
HTH
ardarby is quite right. It's a great option once you know about it to save battery... I use it all the time now, when I'm outdoors if you push and hold in the power button it turns off the back light. If you want it back on just do the same.. Push and hold the power button...
Nice one!
Cheers! I was on the verge of a 20 minute wait to speak to Orange support, thinking I had a hardware fault!
I had the same thing when I had my XDAI. Strangely it seemed to happen every time my gf had been using it, and in the end I worked out she had assumed to turn it "off" it was the same as Nokia's where you have to hold the power button down.
Saved me a similar call to o2!

thanks for the hint, I had the same problem with my qtek 1010, that I got mad at my kids (poor kids) every time they used it I get it back with no back light. It is a bit different with the 1010, you press for power, and then you can toggle between back light on/off by a second long press on the power button.
Well, now I see no need to buy a new one :lol:
this forum is superb! My problem with backlight off solved again
Thanks all
So I was using the camera today and accidentally hit the power button. The screen turned off and the camera appeared to stop, but I can not power the device back on. holding the power button did nothing, nor did just pressing it. Normally I'd remove the battery at this point, but as you folks know, this is impossible unless I want to break my device. Anyone know how I can hard reset this thing or will I just have to wait until the battery dies? (Which will take a very very long time.)
I've had some very weird power problems with my Tab to the point where I'm thinking of sending it in for RMA. It sounds similar to your problem.
After leaving it for a period of time "sleeping", I come back and press the power button, and the display does not turn on.
Over a 5-minute period of fiddling with holding different combinations of the 3 buttons at the top, I got it to hard power off. It does take quite a while to hold them, longer than I would have expected!
My went to RMA. I asked for a refund.

I think all you have to do is hold the power button for a very long time, like 10 seconds. My friend and I both had the problem where it wouldn't turn on after a while asleep and this is how we forced it to reboot.
THANK YOU!!!!...looked everywhere for this. So, holding the power button for 10 sec works.
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).
My power button gradually died over a week after having the phone since release. I took it all apart and let the power button and the little thing attached to it soak in pure alcohol and alcoholed the parts near the power button, it still doesn't work.
Everything else works however, screen starts charging when I plug it in,etc. Is there any way to turn on the Nexus 4 without the power button so I can use it again?
Thank you
just short the 2 golden contacts in the mobo(its what power button does '-') till it turns on
Hi
I've just bought an ex-demo display unit off ebay (with limited warranty from a rated biz seller) and after I press the power button whilst it's in sleep/standby mode, it can take around 15-40 sec for the screen to turn on. On my old Tab-S2 (and virtually every other device) pressing the power button wakes up the device immediately.
Am I missing some weird new feature here or is it faulty? How can I test it?
If I do a screen double-tap it's the same. If I hold down the power button then it prompts straight away to turn off. So it just seems to have the delay whilst it's in sleep/display-off mode. If it's powered off then it starts after about 5sec holding down the power key.
It's no good having a faster tablet if it takes ages to wake up - any ideas?

that's not normal for sure, it should wake up instantly after pressing the power button, you can try to factory reset or flash latest firmware, if problem exists you should return it then.
Thanks for the info - I'd already updated the firmware but it made no difference. I also ran the Samsung Members Hardware test https://www.samsung.com/levant/support/mobile-devices/samsung-members-how-to-perform-hardware-test/ but and the hardkeys check out fine.
However I've just discovered that if I disable "double tap to wake" (option enabled by default) then the power key and fingerprint touch now wake it immediately. The behaviour was rather random though so will give it some time.
Well that turned out to be short lived as it sometimes then went to sleep and couldn't be woken up at all, save for the power and vol down key combo. I contacted Samsung support and they advised me to return it!
