Anyone else have this - has been fine until today, screen *seems* dimmer in the daylight and when i put the camera on it flickers black on & off, seemingly more when i'm moving the screen. reboot does nothing.
Any ideas?

Have you tried disabling geolocation in the camera app?

Stobe led for epic

Anyone know of a stobe light app for epic
Sent from my SPH-D700 using XDA App
Try app called "color flashlight". Under the effects section, there's a strobe light, among others.
I'm sure you mean a strobe light using the LED on the back of the phone. I've been looking for one, too, but all the ones I've seen in the Market don't seem to work on the Epic. Any help would be appreciated.

Yes I am speaking in terms of the LED. Anyone anything?

Try TESLALED and get the donation version he's one of our own here. Great program.
There's a very long delay between hitting the widget led switch (on any app) until the LED actually turns on. It's not likely strobe will work until this delay is removed, if at all possible. The led on my wife's moment turns on instantly by comparison.

+1 on teslaled.. Best light app on market, and widget is perfect..
Traced with Ultra Keyboard from my *Epic*
Thanks for this....works great! I've been looking for an LED light that would work on the Epic for a while now.
The flashlight works fine but not the strobe effect.
There is no strobe LED for the epic because the sensor is made by NEC the libs are loaded each and every time the LED turns on and off, hence the long delay.
Ok, I did a quick test, if I go to the camera and click the Camera button quickly I get almost the same effect....why can't it be programmed the same way and if you say the library is loaded every time, maybe keep them loaded and just call upon them? How does the camera work where it detects you pressing the button and turn on the LED so quickly? I am sure it can be done, but I am not an android developer so I have no clue.

[Q] Nexus 5 sensors stop working at random no output until restart

Hi all, I'm a little worried as I love my Nexus 5 coming from a Desire Z but I'd say from as little as 30 mins to up to 8 hours or so I have to reset my phone as all the sensors stop working. Installing a sensor monitoring app it says the output is blank on them all.
Screen rotation, compass, maps and the barometer all stop working.
Anyone else getting this?
I don't think its hardware as a reboot fixes it for a while.
Thanks
Edit:
It also seems to have resolved itself after a while, when I installed a step counting app I checked and the sensors and they were all working again.
A bit odd...
I am having the same problem. Which step counting app did you install to keep it working?

Hi
It was an app called Moves - but it ate an absolute load of battery life so I uninstalled it rather quick, it was also pretty crap.
I have this issue very rarely now, I just wish I knew what the problem was caused by.
Have you in the past enabled the ART library?

I have not used the ART library yet.
The app I noticed the problem in is 'Reddit is Fun' but It is most likely a background app that is causing the issues.
I uninstalled a bunch of them, including Elixer and PressureNet, just to see if I continue to have the issue.
Ahh OK. I installed an app called barometer+ so I could make use of the pressure sensor. I think it has background logging as well. Perhaps it is this causing it.
I'm having the same issue. Right now I'm just restarting my phone whenever I notice it.

smalovic do you have any weather apps or pressure sensor apps (or anything like that)?
Have you tried the ART libary at all?
Thanks

I have PressureNet installed. I switched to the ART library but I'm getting the same problem.
Hi all,
Same issue here. I'm using syspressure app for background pressure logging. I switched to a every 5 mins sample rate instead of 1. Now I will try to see if it's happening again.
Sent from my Nexus 5 using xda app-developers app
My Barometer+ app was set to hour updates...
I guess we can all relate to a pressure app, probably the cause...
Setting SyPressure sample rate to 5 minutes has done nothing.
After about 30 mins of standby all sensors stopped working again.
Now I have disabled the widget of SyPressure that means no background logging anymore.
I will update the status.
---------- Post added at 09:16 AM ---------- Previous post was at 08:54 AM ----------
UPDATE:
After about 30 mins of standby all sensors still WORKING.
Now I will try to wait much more than 30 minutes
I will update!!
UPDATE 2:
After more than 1 hour, sensors still OK!
I will try overnight and check it out.
Anyway also battery perfomence seems to be better, 1 hour ago charge was at 33% and now is still alt 33%
PS. Sorry for my english
I uninstalled PressureNet yesterday and left it overnight. Everything's still working this morning!
It must be some glitch with the barometer apps.
Same problem here. I also have sypressure on my phone. I've uninstalled sypressure a day ago, and for now everything work fine
I have the same infuriating issue.
My device: Nexus 5
Build: KRT16M
Unlocked, TWRP Recovery, Root, Chainfire's SuperSU
I also have "pressureNET" app installed for logging pressure readings.
After reboot all sensors work fine. Installed app "Sensor Sense" confirms this. Then randomly at some point in time, 2 or 5 or 8 hours later most sensors stop working and it is always the same ones.
Battery, Location, Light, and Proximity all continue to work fine indefinitely.
Pressure, Accelerometer, Gravity, Gyroscope, Linear Acceleration, Rotation, and Magnetic Field all fail and no apps can make a call on these sensors as part of their function.
This is most readily and frequently apparent in (i) the "Gallery" in which rotating the screen no longer results in auto-rotation of images, (ii) orientation of recorded images and videos with "Camera" in which the capture is locked into one orientation and videos shot in landscape (for example) end up with an on-their-side portrait orientation when viewed, and (iii) YouTube videos can no longer orientate when playing and the screen is changed to a different orientation e.g. load video in portrait mode, flip horizontal, and video no change or adaptation occurs, (iv) going into a PhotoSphere results in a black screen of nothing, (v) "Compass" doesn't work, (vi) "Skymap" doesn't work, etc. etc.
Would love to see a resolution to this issue; this is the first forum or instance of discussing the problem on the Web that I have found.
Robooting the device resets everything and all sensors (and apps) work fine as normal.

Uninstall pressureNET, reboot, and you should be all set.

Resolved
I confirm that "pressureNET" was the app causing the other sensors to crash.
50 hours after uninstalling and rebooting there has been no recurrence of the problem; all sensors and the handset have worked flawlessly throughout.

Reading the other replies, it seems as though any barometer app causes the issues.

Damn, I'm having the same issue intermittently. Might have to uninstall the app until they get this sorted out, which is a shame because the sample size for reading in my region is probably very small.
Looks like the pressureNET dev is working on a fix. He posted on Reddit: http://www.reddit.com/r/Android/comments/1qzg0n/nexus_5_sensor_issues_whats_going_on/

Problems with Google Goggles and the N5 camera

I have tried Google Goggles with my Nexus 5.
If I want to take a picture (Barcode, QR-Code, etc.), camera screen changes between dark and bright again and again before I ever touch the screen to shoot or focus.
The resulting picture is always too dark to analyse.
If I open the stock Kitkat camera app simultanesously, the screen is black and all you can see is the blue button. When Goggles is closed, the app works normal.
I was able to try another Nexus 5. Same problem.
Can anyone confirm this (so hopefully Goggles app issue) or is this probably a hardware issue?
Exact same issue here.

Google Goggles crashes on Nexus 5

Trying to establish whether this is a problem with my phone, or an incompatibility with the app but when I load Goggles it works for a second before completely locking up the phone.
The camera works using the camera app, Instagram, Paper Camera so I don't think there's a problem with that?
Phone is rooted.

It didn't crash on my phone, however when using it without flash the image brightness (not the screen) keeps flickering annoyingly.
And after I close Goggles, the stock camera app no longer works (black screen) unless I force stop Goggles.

Cm11 bug am I the only one?

Noticed in cm11 that when I take photos in the dark it uses flash to focus when I first boot which is normal but any time after using the torch app the flash no longer comes on to focus and will only flash with the photo resulting in terrible night shots and white washed out photos? Everyone else experiencing this as well?

What happens, if you go to your recent apps button, is Torch still there?
So scenarios to test.
Fresh boot, Camera, do photos flash?
Fresh boot, Torch, Camera, do photos flash?
Fresh boot, Torch, Recent Apps closing Torch, do photos flash?
Additional, repeat the above but do you actually have to only open Torch, or open Torch and switch on the LED to use as a flashlight and then switch off the LED.
If you run through those tests that would help determine if Torch is the issue.
Fresh boot camera works perfectly normal
Fresh boot torch open toggled on/off camera will not use flash to focus but only during the actual shot.
Fresh boot then closed in recents im gonna flash back to cm11 now to test.

Same results after clearing from recents.....no matter the circumstances if the led is toggled on in torch at all focus flash breaks until I reboot
