screen lights up randomly

Hi all. Since updating to 2.3.5 my screen randomly lights up. The phone will be just sitting on the table, next to bed etc and the screen will light up for a few seconds and the turn off.

Not been on a stock ROM in a while, but I do remember hearing about this problem when the update rolled out. Just can’t remember if the problem was solved. Had a quick search and no joy. I'll keep looking. I have a theory though...
I had this problem once, and it was down to an app and the WiFi sleep policy. The WiFi sleep policy was set to ’15 minutes’ so the app was occasionally forcing a wake-lock to stop the WiFi from shutting off. This would also cause the screen to come on briefly. Could it be something like that? Sorry I can’t remember what the app was. Try leaving WiFi off and see if that stops it. If not successful try leaving auto-sync off. It will at least rule out or confirm something trying to force a wake-lock to sync something.
Edit: Does this do it only when on charge? Try opening up Car Dock Mode, and turning off 'Auto Launch'.

I noticed this too, but only on a Sense 3.5 ROM...Endymion (because, frankly, i didn't care much about any other Sense ROM to stay on it long enough to notice anything) ...but for me, the screen only lit up like a camera flash, just for a fraction of a second! not for a couple of seonds as you have experienced. Been on ICS betas, and RCs and currently on Reaper, but this issue never repeated itself. So far, this has happened to me only on a Sense 3.5 ROM...and my setup, sync frequency, installed apps hardly ever varies from ROM to ROM...I'm pretty consistent about how i like to use my phone.
And frankly, even when this was happening, i didn't bother much because it wasn't affecting performance or battery life... Sense is quirky, to say the least, but i've learnt to tolerate it like you would a sexy girlfriend. If it's sexy enough, it can get away with anything!!

I had this issue on the stock 2.3.3 ROM.

I had the same issue but just one time few minutes after i pluged my phone .

Same here with MIUI... Just for a 1/10 of a second...
...via Tapatalk

I get this on ICS (virtuos quattro) when screen is off and charging, like half a second on and off again...

i've had this issue with pretty much every ROM, actually had it since i've had the phone. The phone lights up for a quick second. Enough for you to realise when your eyes are closed. i don't pay much attention to it anymore. But i don't think mine lasts seconds like yours. Mine was just a blank screen flashing

Atrix 2 dying in sleep (freezing)

Hi all
Sometimes, my Atrix 2 will just freeze when the screen is off, and obviously won't come back on until the battery is pulled and reinserted. (draining it at the same time). It seems to have happened the most when airplane mode was turned on.
I'm afraid all this battery pulling will make the cover loose.
Does it happen with anyone of you?
thanks
EDIT: I'm on 2.3.6 stock, non root.

I have never experienced such a problem... So it just freezes while it sleeping? I have one idea but it's kind of stupid, there is an option under display, that says lock in pocket. Try unchecking that, I've had other people tell me that their phone freezes up afterwards...

You might have to do a warranty exchange.

I've written "drain" but it's not much of a drain - from 100 to 60% in a whole night. A true drain would be with the phone going from full to empty in a couple hours and getting very hot in the process.
I think the phone locks up for some reason during sleep and the cpu never goes into low power mode. As far as I can remember, this has happened only when it was bedtime, with the phone already put in airplane mode, and never in the long standby hours of the day while I work.
I hope this has something to do with software, and not hardware.
(A warranty replacement is out of question, as I'm not from the US...)
I'll try posting in the motorola forum, too.

100-60 overnight is a bit on the high side for drain if you are not using the phone. I would do a warranty swap.

It's probably something to do with the CPU govener. Try rooting, install bootstrap, then flashing the deodexed version of 2.3.6 found here. Just be sure to flash as a backup by placing it in \sdcard\clockworkmod\backup\. Select restore in clockwork and it should be there.
See if that gets rid of the problem You don't mid rooting right

Yes I mind rooting! Sorry!
I was just seeking for your experience, to know if you did by chance notice this behaviour/glitch... you keep telling me to do an exchange but it's obvious it's not an option for me, as you can see from the flag under my user name. Otherwise I would have got me a new atrix already. (Because of other minor annoyances)
I once had an acer liquid that started getting nuclear-fusion-hot and discharged in 2 hours each time, without the software taking a hit. Now that was hardware related.
As to my atrix2, I am sure it's not hardware related, because it happens only sometimes and in certain circumstances. One time, I turned it off and back on 5 secs after and it was already frozen. No way, we're not talking of hardware fault here.

Thats major drain overnight! I leave my phone on overnight and generally get about 1% drain per hour.

WTF, either I can't speak my mind, or you don't read my posts!
It's not that I get a 40% drain every night. In fact I got it only once, last night, when I decided to leave the phone in deep coma after I found it unresponsive after just a few minutes it was turned off and in airplane mode (the time of brushing teeth and coming back to bed, FYI). In that circumstance I got the 40% drain, but otherwise i get a normal 5% drain like yours.
This thread is not on the battery drain, but on finding what causes the phone freezing while screen-off.
Thank you.

I have never heard of this happening on the A2.
When the phone freezes up, does it get hot at all? It's possible that your problem is hardware-related, but the only way to be sure of that is to make sure that it's not software-related...
It may possibly be one of the apps that you're using. If you're OK with it, then I highly recommend to begin with a hard reset. I write down all of the apps that I know I will need and then I reinstall them after the reset, then if I realize I need to use an app I don't have I install it.
Another thing to try is flashing the fxz. This will clear every single bit of data on your phone and reinstall stock 2.3.4. Then you can update to 2.3.6 and gradually regain your (necessary) apps as with the hard reset.

Sounds kinda like these reported bugs below:

You must not be able to communicate your thoughts very well then cause the post I responded to didn't make any mention of the fact it only happened once. And your first post said it happens "sometimes", meaning more than once. Sorry guy, i'm not a mind reader.

I know what the thread is about, but you chose to share your experience with the battery draining issue not only in the first post but also in the once I quoted above which led me to believe this thread was about that as well so that's what I chose to respond to.
Thanks

Yeah, sounds like that. What did you do to overcome it?
Do you use airplane mode at all?

I think I made sufficiently clear that the draining was secondary to the freezing issue, and, in turn, that the freezing issue happened only sometimes... which, in my (surely flawed) understanding, is more often not the case than it is.
Anyways no problem man!

Not sure what fixed it. I have done a couple things since then.
1.) Rooted <- not sure how this could fix a problem like this.
2.) Froze several apps with Titanium Backup. <- This one makes the most sense.
I never use airplane mode.

The other user (dk-v1) says that his softkey lights come on while the screen stays black.
I don't remember about the lights, probably one time they turned on, but don't remember right now.
About the black screen, I'm not sure what he means, but mine stays black and with backlight off.

From reading the OP...I would suspect that it could be an app that is trying to sync while in airplane mode. I would try troubleshooting (uninstalling one by one to see if the problem goes away) apps that sync, preferably the ones you installed. But if it still persists do a factory reset and start over. Good luck man!!!

my wife actually started having this problem with her inspire recently. I tracked it down to the no led app she was using. deleted it and everything has been fine since. so your issues could most definitely be app related.

I never said it was the primary issue......u said this thread wasnt about the draining issue, but since u brought it up in your op and subsequent posts its clear it was an issue so when somebody responds to one of the issues you're having, don't be a douchebag about it by saying "thats not what this thread is about". Trying to insult me by insenuating I don't read before I respond is no way to show appreciation for my attempt at helping you. It seemed you were under the impression that a 40% discharge overnight wasnt a major drain so I shared with you my experience thinking it would put yours into perspective.
But apparently explaining my thought process and posting your own quotes for you to see how/why I'd think what I thought isnt enough to knock you off your high horse so I'm over it, carry on. If you feel the need to respond any further you can pm me, no sense cluttering the thread any further.

Phone screen won't come on!

I'm not sure if it's lag or what, but my phone screen won't come on. I think it's a ribbon that was disconnected or something though. For about a few hours if I were to press power to see the lock screen, all I saw where a bunch of rainbow static. Then I powered my phone on and off because nothing would work and now it's jut black! Does anyone know what's wrong? I can't boot into clockwork so I don't think it's a rom problem. Does anyone know the problem or have any idea to fix? Anyone I should ask specifically?

maybe water? even having my phone in the bathroom while i take a shower cause me that

It's not water, I never bring my phone close to place with water :/

can you boot into the screen where there are 3 droids with the skateboards? (i not sure whats the name)

I think I can boot and my phone still works, because it still rings when someone calls and it still vibrates when someone text it, but I just can't pick up or reply (because the screen won't come on). I should be able to boot into that thing, but I can't anything :/

well bro sorry i cant help you :/ maybe it could be the screen,the ribons or somethings loose. did it fell?

Seems like either broken ribbon that connects the screen to the "motherboard', or dead screen itself. That's exactly how 1 of my phones died (it was too complicated to disassemble and fix it myself)
But once I had similar problem with my TP2, the screen first become unresponsive to any touch, and then it went just black after restart (and every next restart). However all keys did work.
Hard reset somewhat helped, the screen actually came back, but it was still stuck on setting up Windows Mobile (if you know WinMo: the part where you calibrate touchscreen), apparently "touch" part of the screen didn't work.
I thought it is ribbon or screen assembly, but since all the keys worked I flashed another ROM and what do you know: all problems went away. It worked fine for as long as I had it. I never figured out what caused it/was the problem.

Busted phone for a Dev if you want it

Alright guys, I had a conversation in Ax's "Run ROMs on different Carriers" thread, but I really want to get to the bottom of my issue, whether it be a hardware issue, ROM related, OR user related.
I've been having an issue with my phone the past few days. Started out it would read "invalid sim, need to reboot" or something along that. Anyways this was after flashing a nightly and I figured, OK, it's a nightly i'll live with it. Eventually my phone just started to power off/reboot all by itself; not real consistent but it was happening more than I would like. Today, the S*&% really hit the fan. I flashed a nightly Wednesday night(i'm not going to say which one, because i'm not sure if it was from the ROM itself or if this was a hardware issue). Anyways, Friday at about noon or so, I open a game to play on my lunch break, I get distracted so I lock my phone to attend to something else. I go back to my phone and it is powered off, now totally unresponsive to anything. I pull battery and try to restart, when I place the battery back in the phone it automatically reboots(WITHOUT ANY BUTTON PRESS) I thought to myself ok this is kind of weird. I try rebooting by using power+vol up...absolutely nothing, it's just a brick. Well, I pull the battery again, hold vol up thinking it will go into recovery...nope, it will boot for a sec or two, just enough to get the blue lettering on the top left of the screen then shuts off again. OK, let's put this b*&*h into download mode and see what happens. it goes into DL mode, all the way to the point of where it says " do not turn target off" then shuts down. I did both of these multiple times, with different batteries as well, plugged in and not. It won't stay on for a computer to recognize it. Someone suggested a stuck power button, I don't think so; it feels the same as it always has.
I was fortunate enough to be able to get another S4 with a busted screen so I switched out motherboards. I have a working phone again...which is all I was worried about. I've flashed quite a few ROMs, I follow procedure to the T when flashing... What do you guys think...hardware issue...user issue...ROM issue? I'm very curious to know because I don't want this happening again, obviously. I would even send the phone out to someone to play with(mind you, the screen doesn't work and the silver bezel is crappy because I just used my original one).

I would say stay away from whatever ROM you flashed. This could also be a hardware issue. I had my old note just randomly shut off on me and was unresponsive as well. Finally got it to boot and reset it. But in your case I would stay away from that ROM and maybe find something more stable. So as this is unknown to what happened I would not blame either. Sorry to hear about your bad experience.

Im saying nothing for sure, but a stuck power button feels just like normal. I had this issue on two separate samsung phones (they are known for this issue). I thought it was just bs, but i decided to tear it down and check. I used a q-tip and everclear and got plenty in there, wiggled and pressed the button for around five minutes. Re assembled, put the battery in and sure enough, the problem was gone. You cant always feel the button sticking. But hey, if you are offering the remains up, ill take em! I would gladly pay $200 for a replacement screen for it to test on.

Someone beat you to it, Rebel, sorry...just took the first poster or PM that I got. I got the message overnight otherwise I would have posted in here.
I kinda played with the power button when it was tore down, however I didn't use any alcohol on it but that is a good idea.
Sent from my SAMSUNG-SGH-I337 using XDA Premium 4 mobile app

Edit: Used some IPA on the power button this morning, soaked it pretty well, pressed the button many many times with varying pressure, with a hard pointy object etc. etc., jiggled side to side, tried every option I could to get it unstuck (if that's what it is) and still doing the exact same thing.

Press Unlock / Phone goes right back to sleep.

I've got a problem. Same problem I had on my G2 and I ended up getting rid of the G2.
For some strange reason at times when I press the button on the back to unlock/wake the phone the screen comes on and it goes RIGHT BACK to sleep.
At first it seemed like it was when my hand is touching the top of the phone but this morning I couldn't duplicate it on command.
Any clue whats happening?

I know this isn't any help to you, but I am seeing the same behavior. It took me 5 minutes to get the phone to unlock last night. If anyone has any ideas on this please help! Thank you in advance.

No it can be anytime. Usually if a finger is on the top of the phone but not always there and not every time it there.
Its weird.

The only thing that I can think of is the feature they use with the sensors next to the camera on the front. If your phone is in your pocket and the power button is pressed the screen will shut back off. You can test it by holding your hand over the proximity next to the camera. Then press power.

I know I mess up when I disconnect my phone from the power cord in the morning. The phone's screen automatically comes on when you unplug it, but I have a habit of trying to turn the screen on myself. What happens is that the phone automatically turns the screen on, and my actions immediately turn it off again.
I realize this probably isn't the same issue that some of you are facing, but it does annoy me!
