my screen turns "on" itself to standby mode - Nexus 4 Q&A, Help & Troubleshooting

Hello, when it happens something that I do not understand with my N4.
Whenever I lock my N4 pressing the button the screen turns off after a few seconds but then (this is random) it turns back on itself, arises on the lockscreen (my home is a diagram) and shuts itself anew after 2 minutes (because it's my time to sleep after non-use).
It breaks my head.
Have you any idea?.

Any special app ?

I do not know, this is not for a particular app.
When I use my phone normally and I put it to sleep, it locks, but the screen turns off after a few seconds the screen turns on for no reason.
And this happens several times per hour alone.
Sorry for my bad english, i am french.

I have the exact same thing! It's annoying! I presume it's a program I installed, but I don't know which. And I'm too lazy to uninstall them one by one... Any program I can use to see what's waking the screen? I'm not rooted btw...

Yes I think that is the cause of a program but I do not know which.
Is there an application to list the process?

Have you installed 'flipturn' or whatever it's called app ?

I don't have an app called flipturn. I don't have any app that starts with the word flip...

Me too i dont have an app called flipturn..

If you don't have any "special" app, I would do a factory reset

It's not bothering me so much that I want to lose all my save data by doing a factory reset....

I had this issue and figured out how to fix it. Problem is, I don't remember how I fixed it. I think it was due to an app waking my phone. Check your apps to see if any of them have the permission to wake your device.

So I made ​​the restoration, i havent had the problem for more than 24 hours (I know because I watched all the time to see if it was ok or not after each lock, I watched as the one for minute)
But since today is the problem recurred.
So what I'll do, I'll redo a restore with the factory image but not new to reinstall my applications because it has to be somewhat of a blind application of the play.
Because I do not think the problem is hardware or it will be declared soon after the restoration, or it is returned after a ten hour (just after installing all my applications because I do not make on).

Its an apk, I had that problem with this apk..

It collects data on and off screen.

I wish I had that app so I could just remove it. Unfortunately I've never installed that app so must be another app.

Android system eating battery!

Hey guys, i got my Samsung S3 yesterday after having my S2x for 8 months. Really happy with the phone except for the battery life. My phone dropped 15% in 1 hour with screen on for 15 minute in Wi-Fi. This is the screen shot of my battery...

its syncing all your google stuff dude. aka contacts apps and any settings you have set to auto backup.
I'll try turning off sync for the day, see if that helps
Thanks for the reply!

Syncs a major killer, first think I turn off. If you root, theirs no need for most of the stuff it does

Can you explain why rooting eliminates the need for the functions "sync" provides?
Do a factory reset. Syncing has nothing to do with this issue. I sync three emails, facebook and twitter. I am easily getting 15-20 hours with over 2 hours of screen-on time.

Because you can use titanium back up for everything, I still use Google sync tho, the first days is the ones the takes the biggest hits after that I think is fine unless you keep updating contact and what not

If there was a way to sync Google contacts only when a contact has been added on the device or from the web, I'd turn off autosync. The random syncs seem to be my problem, but I'd be up the creek without them.
Don't think sync is the culprit - I have had android phones for quite some time now and they all been sync'ing same amount of data - no such drain. This is something SGS3 specific. There's a lot of modules listed under Android System. One thing I suspect is that I switched network to EvDo/CDMA/Something/WCDMA, which might be not a particular good idea. Turned back to CDMA only, since LTE is not available here just yet (waiting for this damn Sunday!) and will see if that improves the stats.

I had GPS toggled on the past 2 days and got horrible battery life and high Android System use.
Toggled it off today and it has been much better.
The weather app likes to use it. And I also noticed it firing on randomly. Just turn it off. Maybe it's the GLONASS support, but it sucks down battery particularly well.
I wish Google would separate out Location permissions from GPS permissions. Then in CM9/10 we could just uncheck GPS permissions.
Some apps I like general location, but they have no business using GPS.

[Observations/Results] XXLSJ Lockscreen/Device Wakeup Freeze

I'm sure almost everyone has now experienced the freeze that happens sometimes when the device comes out of deep sleep, usually for a couple seconds.
I (personally) think its the only thing from making this ROM pretty near perfect. I have been trying to get to the bottom of this freezing issue for a few days and I'm sure a lot of other people have been trying too!
I have disable a whole bunch of things, and since it seems it could be related to WiFi (as many are reporting) I started disabling and uninstalling apps in different stages. Iv ended up with the following (see screenshots) disabled/uninstalled and have been repeatedly locking and unlocking the device (letting it enter deep sleep first of course) and have yet to experience the bug again.
Maybe it doesn't work for you, but perhaps someone can pick up from here and we can all get to the bottom of the problem! It might be impossible at this stage and may simply require a newer leak/release of JB for the i9100.

Hopefully this helps, if not I apologize, but think the problem needs any insight available
I have not freezed, deleted all the extra functionalities and stuff, but the problem is still there, even worst on wifi. I gave u a thank for make a step up to try to solve the problem
I have removed almost every single samsung app from syatem. Using apex instead of TW. Always have wifi turned off. Because i use my data plan. As its unlimited. I have this problem all the time. Is there anything i can do to help? Logcat or anything.

I think its a touch panel driver problem but better to do a logcat if you have time for this. I also have experienced the problem when trying to end a call.

Yes, last night I was using logcat and when the screen came on and froze the logcat contained data such as waiting for input, loading mali driver for touch recognition. I laso thought it could be related to motion control, as if its waiting for acceleration from it so as to use the camera motion shortcut etc but alas disabling motion didnt help either
Will upload a logcat or two later after college today!
It also happened to me too when trying to end a call after the screen came back on after taking the phone away from my eat. Ive also noticed that when the screen comes on and touch is unresponsive. The menu and back keys at the bottom are not lit. And after 4/5 seconds they light up and then it is working. Will post a logcat when i next experience it.

Tried many lock screen apps including the stock one, random freezing with all of them with wifi on. Have been using Holo Locker for a couple of days, seems to fix the problem.

I get around it like another user suggested,
I have a tasker that turns my wifi off when the screen goes off.
I also have phenomenal battery life this way. It is definitely a wifi issue.

[Q] Galaxy S4 standby doesnt work

So i've had the S4 since it got released and i like it,
but for some reason the standby doesnt work at all.. i have it set to turn off the screen after 30 secs of idle and it does not work.
anyone else having this issue?
mine works fine. see what apps have been installed. maybe some app requires not to go in standby and prevents the screen to go off

Have similar problem - screen do not off completely. Does not mateer what time I chose, does not matter if smart stay is on or off. I do not have it's icon visible in the status bar whet it is off. Anyway screen is always on. Any help?
Same problem here. The phone just dims its screen but it never shuts it off.
This is quite annoying when the phone lights up to show the low batt warning and just drains all its remaining energy. Perfect.

Try disabling all smart stay options (smart pause could still be on).

Seems that I found the reason. But still do not have permanent solution. After restart screen went off without problem. After running some application it became constantly on again. When I closed some applications (long press home button and swipe open applications) screen also turned off normally. So probably some application makes such a problem. Have to check which one.

GPS Battery bug

Hi all, got my Note 3 Thursday and I love it, came from a Z1 and what I love the most is the battery life. I'm a pretty heavy user and so far I'm getting at least 6hrs screen on which is awesome for me!
Anyway I noticed today that even though my GPS hasn't been on its showing on in battery stats

but when I did turn the GPS on it shows its off, it's like it's inverted strangely....rebooted phone still same.
I will back up and factory reset it tomorrow, but wanted to check if anyone else had this before, I did search but nothing came up. BTW I'm stock unrooted.

A colleague of mine is having same problem but with wifi, it's inverted....I will point out though it doesn't seem to have an effect on battery life. Must be a visual bug.
Sent from my SM-N9005 using Tapatalk
Edit: mine wasn't inverting like yours, just showing the gps on when it was off.
I isolated this down to google maps, I didn't notice a drop in battery, but It bugged me none the less. Once location was blocked in Xprivacy it stopped reporting GPS-on in the battery stats. This might fix it: Try temporarily disabling google maps from app info and see if it stops, then re-enable.

OP screen looks strange and looks nothing like mine: I have GPS on all the time and actually used maps for driving from work today and GPS shows active only when screen was on. With screen off on mine GPS shows off as well, where OP shows GPS active all the time. I wonder if OP has some program requesting GPS position at all times, even with screen off. Maybe some anti theft tracking or showing OP position to friends and family? Maybe same program over rides off setting? I never heard of settings being inverted, but maybe there is some system error.
Thanks for your feedback, after trying a few things: disabling Gmaps, rebooting device, turning off location services still no joy. So before doing a factory reset I reset the app preferences, which you can do but going to settings>app manager>all>press menu and then select ' reset app preferences' and it worked.
So it must if been some app causing this, I don't have a tracking app apart from the Android device manager, which is on, a bit stumped what it was but now glad it's gone as my OCD was going through the roof!! ?

I had the same problem,all my GPS settings were set to off but somehow the Battery stats were showing that the GPS was all time on! I tried many things until I found the real culprit, and in my case was not the OS software but an App that is keeping the GPS on despite closing it! The App (2GIS) is of course related to GPS as it includes navigation among its features.The solution was to close the app and reboot my device instead of deleting that app as I really want it! So I will advise anyone with this problem to find every app on their phone which uses GPS and monitor them, hopefully you will track down the culprit!

Stuck in landscape mode!!

I'd be lucky to have my phone stuck in landscape mode Cuz usually you can't do that on the launcher without a rotation locker app. But anyway, try restarting your phone. If your lock screen goes sideways immediately, or your boot animation goes sideways before the lock screen, it has to be a system setting or kernel declaration. If your lockscreen stays portrait for >5 seconds but then goes sideways, it's an APP that's doing it!! Check for any games you've installed, any games that lock sideways and force quite them+clear data. See if that does it.
Post back your results, and I'll try to help you more,

That's weird.. a problem that shouldn't require a factory reset. I'm sure it was some app with load-on-boot privilege or some setting somewhere. I'd still like to know what caused it.

I couldn't find anything. I looked everywhere. It was weird because i had just pulled it out of my pocket to check the time. Lockscreen looked the same as always. I noticed i had a missed sms so I unlocked it to respond and was then stuck in landscape. I didn't notice if it went right to landscape or not. Funny thing is I could rotate the screen 180 and the image would be totally inverted. Made me think the gyroscope sensor was on the fritz. Wasn't there a way they could be calibrated in the past?
what launcher are you using?
Switch back to stock TouchWiz to validate if it's hardware issue - but it's most likely just a setting in your launcher.
