Screen Switches On/Off Continuously

Since a week ago my DHD screen started switching itself on every few minutes. The phone doesn't unlock but keeps lighting up which is annoying esp at night! I'm using stock 2.2.1 Sense so can't understand why this started happening. Reset or removing battery doesn't do anything either
Anyone else had this or found a solution?

I had a similar problem with my HTC Desire. I found it to be a problem with the power / lock switch on the top of the device that was getting 'stuck'.
Can you confirm if what your experiencing is the same as if you were to continually press the power / lock button on the top of the phone?

Yes, it's basically the same as the power button being pressed. I wondered if it might be stuck but it doesn't look any different or stuck..

Just out of curiosity, could the phone have been exposed to water at any point?
It's indicating to be a hardware problem since you have the Somebody on HTCPedia.com was having a similar problem and this seemed to solve their issue:
I had the exact same problem and it was (most probably) also caused by exposure to water: I had the phone in my pocket while cycling through rain and it all got wet. Since then, the power button got stuck, as in it was always pressed but sometimes was getting released depending on how the phone was held. For me, this resulted in the batter being drained in about 4 hours since it kept bringing up ShutXP.
EDIT: Do not use a flux remover (de-flux) solution/spray like I described previously (now deleted). In my case it worked for about 1 day and then then button was completely irresponsive which is a worse problem than having it always pressed (if you take the battery out, you can't turn it on).
I was inspired by a solution in another forum. I used surgical alcohol that yuou can by at any pharmacy. The higher the concentration, the better (I used 90 deg).
Take the battery out first !!!
Effectively, you drop a few drops of alcohol inside (yes, inside!) the phone through the small cracks around the power button. I used a pipette but dipping cotton in alcohol and then squeezing also works. Don't worry about dropping to many drops of alcohol ... it dries very quickly. I then blew in- and shook the phone strongly (this was important) to make the liquid advance a bit inside and also to dry it. You then need to leave the phone to dry. You can speed that up if yo put it under a desk lamp.
All solved now. Power button now works fine. What happened probably was that humidity/water created a short circuit, giving the same result as keeping the power button pressed.
If the above doesn't do the trick, you can try to unscrew the plastic shield that covers the button, remove the external button and access the real micro-mechanical button that is soldered onto a very small pcb. You give that one a good clean, rubbing it generously with a small piece of cloth dipped in alcohol. You can also try scratching the surface between the button's soldered pins since that's where a short circuit probably formed in the first place.
Hope you fix it.

Hope this helps

Thanks a lot for the help. This is why xda is such a great forum. From this I worked out it is the power switch and after playing with it and seems to be working on for now. If the prob happens again I'll try the alcohol trick above.
Thanks again

No problem at all, glad to be of assistance

Phone only charges when it is off.

Starting two days ago, my phone will only take a charge when it is off. When it is on, it acts like nothing is happening when I plug it in, although sometimes it flashes the charging symbol whether the charger is plugged in or not. I have the latest atop build, although I have been running the rom for a couple weeks with no problems. Also, the gps struggles at times. Any ideas?

Same problems here with charging...you are not alone!!

I had this problem too. Was gonna take it back to Sprint so I Odined back stock and it's started charging. So try doing that. It worked for me.

My wife had that issue when we first got her phone. Ended up re flashing the ROM. I still ended up getting it replaced by VZW since it had the issue with dropping signal.

Had this issue with my VZW Gnex. It looks like it is charging when it is off but I'm willing to bet it charges really slowly. There's a defect on GNEX models where the pin on the connector gets bent down.
Try either using the stock charger as it forces the pin up a bit or search on xda for this same issue. I fixed it by using a thin knife blade and gently pushing up the connector. I only had to do it once and it worked well.
Hope that helps!

Hi, I've been having this problem since a couple of days and this post just remembered me that I had run into the same issue in my very old Motorola Milestone. Here's what I did then and what I did now on my GNex, and I think i've found a solution.
You'll need a needle (the thinner the better) and a can of electronic cleaner, if you've ever opened a PC to clean the memories and slots, this is the one you've used alongside the compressed air can. You can find this on your local electronics shop, and it shouldn't be too expensive (think of an equivalent of RadioShack, since in my country there's no RadioShack).
Now, let's get on with it.
Turn off your GNex and pull out the battery.
Now, VERY GENTLY, with the tip of the needle try to pick out all or the majority of the lint deposited in the charging port. You'd be amazed.
To wrap up, apply a bit of the electronic cleaner into the charging port, clean with a cloth the excess on the chassis of the phone (do NOT use the cloth into the charging port, because in doing so you'll risk leaving lint behind) and let the charging port dry for 5 or 10 seconds, it evaporates really quickly.
Now put the battery back in and power on the phone once more. Let it fully boot and plug your charger in (as recommended in this post, you may want to use the one that came with the phone). In my case it worked.
Not sure if it's definitive solution but it does work now. This happened to me about a month ago running AOKP, I thought it was the rom doing some funny bussiness with my phone, so I switched to Paranoid Android, and it happened once more the day before yesterday. I was ready to switch roms today once more but decided to Google around and again, thankfully I came across erodriguez87's post which reminded me of what I did in the past. I'll update this post for this next month to let you know if the issue happened again or not, to encourage people to apply this solution (or not). Cheers.

I used a toothpick to bend it up slightly (towards the screen). I didn't want to use anything metallic in case shorting the connectors might cause damage.

Weird thing!!
As everybody here I am having this very same problem, not charging anywhere (mains or pc), even with stock cable and charger.
However, when I tried the eSATA port it worked fine, and I can access the phone normally
Any idea why?

Solution ?!
I had the charger read normal USB ports and charger.
I have done these steps so far, so I guess they must be the solution, however I do not know if the solution is permanent or as some people pointed out it is a come-and-go problem, anyway here are the steps:
- Restart bootloader ( shutdown your phone and hit all three buttons together - GNEX - and press volume down button once and then power button, then volume up and power to start phone again).
- Enable Developer Options ( You do this by tapping several times on the Build Number in About Phone)
- Enable USB debugging in Developer Options.
Again, I don't know which solved the problem, and if it is a permanent one, anyway try it and let me know the result

My son is having exactly the same problem, his Galaxy Nexus only charges when it is turned off.
I found a solution (sort of)....
I discovered that when I put the charger in the wall socket 3 times quickly after eachother (like: tak tak tak) and leave it in the third time, it sometimes starts to charge.
maybe you have to try it a few times to see it work, it doesn't always work.
It should work within 10 times trying i would say.

galaxy s4 randomly shut off???

I've been using my s4 for about 10 days. everything's fine but it has happened like 3 times the phone just shut off itself without me touching it. it's in my pocket, and i was using it like 5mins ago, then when i take it out i found it's totally off already.
the battery had enough juice at the time and the phone didn't feel too warm either. i totally have no clue why this happened. anyone here is experiencing the same thing with your s4? :crying:
for the first two time i can just press and hold the power button to turn it back on. but today when it happened the third time, the press and hold didn't work until i took out the battery and put it back. when it's on, the battery still had like 70% power.
this is frustrating... should i contact t-mobile for an exchange?
p.s. i rooted the phone and from what i can recall, besides titanium backup i didn't install any new app that i didn't have on my old htc sensation. the sensation didn't have this random shutting down problem. (i don't think the titanium caused either).

It used to happen on my s2. But I change roms and it went away.
Change rom and see what happens.
If possiible go full stock for few days.
Otherwise return it.

Mine has done the same thing twice, first time assumed it was me (before the latest firmware upgrade which "improves stability") the second time it was in my pocket, took it out and it was off - thought battery was dead but tried to switch it on anyway and guess what, battery was 90%+
Have no idea why it shut off - stock rom, only "odd" app is Good for enterprise .
Could it be related to overheating in the pocket?
Anyone got any ideas?
W.

Happen to me and to some other Italian guys, too! In my case, the I9500 turn off itself, sometimes reboot itself, just now! Depends from the rom, I don't know why. One rom reboot it, try another rom and after a bit of second shutdown it. And always after tha the display go off
I9505 not, it had only the problem of the audio crackle, for now.

I am also having this issue , please if someone can help...
I am having an i9500 (octa core version) and running United Arab Emirates 2013 June 4.2.2 I9500XXUBMEA I9500OJVBMEA firmware (stock , no root) , frequently when the phone is locked it will shut down on it's own and I have to keep the power button held a bit longer than usual for it to start (like 20 seconds) , I do not want to root it because the company I bought it from is not that...good....so I am very afraid of sending it to their service department , please , any info/suggestions would be greatly appreciated

There is some update about this problem?
I have stock, randomly turns off, sometimes I have to take out the battery to turn the phone on.
It's the only problem I have with the S 4, for the rest is the perfect phone

Sutting itself down
Hi
My S4 is randomly shutting itself down when in my pocket, can you advise how to rectify this situation please?
Thanks

Ok so i may have isolated the cause. at least a physical one. I am an electrician, and i do a LOT of repetitive tasks so i love listening to music while i work. thats when i noticed a pattern to the problem. and this will blow your mind.
( I do not recommend you try this yourself unless you particularily like the sound of 700$ going SNAP)
i took my phone out of my pocket, and by pressing both thumbs on the center of the screen and physicaly bending the phone forward, ( Dont give me crap for this, im smarter than most and i understand limitations. I was impressed that this phone can bend nearly a full 1/8th of an inch!) i was able to replicate the problem.
My theory is, since samsung used a softer plastic for there entire frame, and since the phone is so thin, when ever id bend down, (Pulling pants tighter across my thigh with the phone facing my leg) it would bend and physicaly seperate the metal pins that contact the battery.
PS: just got home, DGAF about spelling right now. is it this hot for anyone else right now!? lol

I've been running the GT-I9505G play edition phone for the last month and only in the last week has the phone began to reboot on its own. What's strange about it is it usually happens when I'm not using the phone. I've seen it reboot maybe a dozen times over the last week. The phone always reboots and doesn't just turn off.
I'm going to see if factory reset takes care of the problem, if not I guess back to Google for a retread...
Thanks B

Yes I do a lot of bending down and I always have my body in awkward angles while working on the flight line and I used to have the same exact problem at work. I always thought that my S4's shutting off was due to the tiny half a mm gap between the bottom of my 7500mAh ZeroLemon Extended Battery and the bottom of the phone's battery slot, in-turn causing the battery to move inside my S4 and make the battery disconnect from the pins. I noticed a tiny gap in the fitting of the battery to the phone and that the battery was never really snug as much as it was with the 3500mAh Anker Extended Battery for my S3; it's really easy to remove the ZeroLemon battery and thought the battery shouldn't be easy to remove.
So I figured it was either the gap causing it to shut off or my movements somehow causing the power button to be pushed while it was in my pocket. I had a feeling it couldn't be the latter though because the thigh-located cargo/map pockets of my ABU's are a bit too large to not have enough room in the pocket for the power button to be pushed. I ended up solving my shutting off problem by cutting a very small piece of thick, durable paper the length of the S4's battery slot and I used the paper as a shim between the bottom edge of the ZeroLemon battery and my S4's battery slot to close the miniscule gap. Since I did used a thick piece of paper as a shim, I've yet to get any sudden shut-off's... even with the amount of times I bend down and move in ways that would cause it to shut off.

I just recently have same issues, it is turning off while the battery is not dead! i have tries to reset the factory setting but it dose not help at all.
what frustrated that Samsung mobile costumer services in UK is not helping much!!!
any help please

if your phone shuts off and than you try to restart it and the battery is a lot lower than before than your battery is broken

I get exactly what you describe, only takes a slight bend to shutdown. doesn't do it with the back cover off, without the cover the battery moves out slightly and the phone stays on.

Help! Screen keeps turning back on after turning it off.

My vzw galaxy nexus keeps turning the screen back on as soon as I turn it off, killing my battery at an average of an hr, at most 2... Downloaded an app that tells u which apps are turning the screen on (wakelock) and it says none... App also tells how long phone has been awake vs asleep... Phone been awake for about 95% of the time... Please help... Phone almost unusable unless connected to charger... Oh, btw... As soon as I plug it in to the charger the problem disappears...
Running unrooted, stock 4.2.2 from vzw... If it helps...

If you've used the app, you should know there's hardly anything random about it. When a particular wakelock has exceptionally high usage, Google about it (can be done from within the app) and get some insight into what is triggering it. Then you can disable/suspend that app/service.

Mine was having the same problem, but I followed the advice of an earlier post by Godra and it has stopped turning on automatically. Basically, I used my pocket knife to clean out under the pins in the micro USB charging port. I also bent it up just a little bit (be very careful not to break it) to keep it away from the metal housing, which is a ground. Something must have been shorting one of the pins to ground (the housing) causing it to continuously wake.

Prying or cleaning the USB connector did not help in my case. Battery charge indicator sometimes stayed on, but sometimes not. Battery drained really fast.
I bought a charging flex connector board replacement (they are really cheap on ebay), watched some youtube videos explaining the how to change the board and when my new board arrived, my phone was fixed in under 15 minutes.
My gnex now holds charge for over 24 hours with moderate use.
With Jelly Bean 4.3 installed and a new charging port, it feels like a brand new phone!

Hi,
I have developed an open-souce (GPLv3) app that helps save battery when this happens.
http://forum.xda-developers.com/showthread.php?t=2484871
SnooZy Charger turns off the screen on these ghost connections, saving battery consumption by the display. It does not fix the charging issues, but it reduces the battery drain when this happens.

ps: sorry if this is considered as self promotion or xposting but this issue has been reported on multiple threads..

Hi, i had the same problemen as you all, but i solved the problem by remove all the dust from the input of the charger connection from the phone. I think that the dust was maken some kind of shortwire and that that was the reason for it to turn on the screen, after i cleaned all the dust from the charger point in the phone, my problem seems to be solved. Can some one else confirm this?

I happen exactly that, how could you fix it?

Had the same Galaxy Nexus problem with the display switching on sporadically or turning back on seconds after the phone was manually switched off. The display was the number one consumer of energy due to energy statistics even without using the phone. Bluetooth, GPS were disabled and no special apps were running on the phone.
Hint:
The battery statistics graph's detail view logged charging events although the phone was not connected to a USB charger/port. The display was logged as active parallel to these events. So basically the phone thought it was connected to a charger and switched on the display which it normally also does, but since this charging status was repeating over and over, the display wouldn't turn off by itself.
Yesterday, I examined the USB port with a magnifying glass in bright light and noticed quite some fuzz build-up in the port. Otherwise the port looked good and not oxidized or damaged. So I removed the battery and cleaned off the fuzz from the micro USB port. I used a thin thread to loosen the felt-like lint which took me quite some time. Vacuum cleaner didn't work well. Compressed air might be helpful.
What shall I say: The phone charged very well and behaved normal the whole day without any unusual drain and NO pseudo charging events in the battery statistics!
Should this success not persist, I will report ...

Screen Rotation Not Working

I was having this problem before a little and I would just do a simple reboot. However, this morning my clumsy niece dropped my tablet on the floor Now the rotation is not working at all.
I've seen videos which lead me to believe that the issue is due to a loose ME571k cable. I have tried fastening it. I inadvertently took it out and reconnected it. I've tried to fasten it the best I can. The touch screen works. However, orientation is dead.
There was a program mentioned called "Test My Android" and none of the sensor calibrators show any sign of life.
This is driving me crazy. I don't know what to do. Maybe it is loose and I just have to keep on messing with it but it's stressful.
Any advice?

Yes it is - for sure. The 'rotation' sensor is a tiny chip which is unlikely to be damaged by a drop.
re-seat the cable on both ends
spray the contacts of the cable with Electronic Cleaner if possible
apply a layer of thick tape over the cable's motherboard connector, so the back cover will deliver extra pressure on it
Let us know...

Hello, I followed the steps of next video and my screen rotation has fixed
