I noticed it today when I had been listening to audio over my bluetooth headphones. Had you been doing similar?

I notice it happens as a result of my Pebble being connected. Do you have any "smart" devices connected to it?

Yep I have a Pebble too.

Same here, I have been running it alongside my Nexus 4 (alternating days, same apps, settings, etc.). Nexus 4 is still on Jellybean, Nexus 5 is obviously on KitKat.
The issue might just be with KitKat because I don't have the issue at all with the Nexus 4. My next step will be to flash KitKat on my N4 and see if the issue starts happening there as well.
Obviously there is going to be some sort of battery drain when Bluetooth is enabled but there is a HUGE difference between the drain and wakelocks on N4 & Jellybean and N5 & KitKat. Hopefully it's software only.

Anybody figured anything out with this? I am getting bluesleep and msm_serial_hs_dma wakelocks. I use a Pebble also.
Edit: Saw there was a thread for this on the Pebble forum and they apparently deleted it because I had to view a cached version.

Unfortunately, my Nexus 4 is out of commission for the time being but I did get some (not very conclusive) data that showed the issue is not preset with the N4 & Jellybean.
However, I found more information regarding the subject. I found this post on the pebble message boards that seems to confirm the issue lies mostly with the Pebble watch. I tested this by disconnecting my watch but leaving bluetooth on (both with it connected to nothing and on a half an hour drive with my N5 connected to my car). The wakelock is nowhere near as crazy as it is with the Pebble.
Doing more research on the bluesleep wakelock in general yielded a couple of results here in XDA ranging from missing binaries to kernel bugs. The fact that it's only happening to the Pebble is interesting however.
I wonder how other Bluetooth "smart" devices do with the Nexus 5. I don't own any other ones but if someone else does that would prove an interesting test.

Seeing the same thing. Got a Pebble yesterday and seeing the Bluesleep wake lock in BBS.

edit: wrong thread!

Has anyone been able to test this with another Bluetooth data device (ie: not a headset)?

Same Blue sleep issue
I'm having the same issue.
Running 4.4.1 with ART runtime.
Using Sony bluetooth headphones.
Over 2.5 hours of wakelocks today.
Wasn't an issue on 4.4 so must be software glitch in 4.4.1
Will need to post it to Android code database so it can be locked into.

I have the same with Android 4.4.2 using ART: Pebble app has 4h 8m of keep awake on 6h 36m total. I found a fix for bluesleep wakelock for Motorola Atrix, probably someone could build one for N5.

I think that the wakelocks issue is related to ART; I switched back to Dalvik and now it seems working fine as before.

Same issue for me now, Galaxy s4 running GPE ROM on 4.4.4 with Pebble Smartwatch. Almost 100% awake due to BT. If I turn off BT thongs go back to normal ...
Any fixes yet?

Same problem with jawbone up24.

I have the same problem. Started when I installed the beta XY findit app for BLE tags.
I have uninstalled that now, but whenever I have bt open, the battery drains blazingly fast. no BT headsets or anything. I mostly use the bt to interact with iBeacons.

i have been having this issue a lot to. seems to be caused by my pioneer nav in my car. bluetooth does disconnect however bluesleep wake lock stays going until i turn off bluetooth. hasnt always been a problem. started maybe a month ago. very strange. running slim rom. happens with stock slim and elementalx kernels.

I have had this issue a few times with certain versions of Franco kernel. I have a Fitbit Flex that syncs with my phone.

Proximity Sensor ignored in some orientation?

Is anyone noticing this happening to their Nexus 5?
http://www.youtube.com/watch?v=cjTGQaK1Qvw
That's actually my video I did for the Galaxy Nexus. Google fixed it in an update, but looks like the Nexus 5 and the current KitKat 4.4.2 is doing the same thing!
I could recreate the same thing in the video with my Nexus 5 (not rooted, 100% stock ROM).
The reason I looked into it was because I noticed that I keep accidentally face-dial or hang up on people when I use my shoulder to hold my phone against my face. I guess holding it that way is enough of an angle to simulate laying flat on a table, thus disabling the proximity sensor.
Doesn't seem like a bug, but by design (albeit a BAD design).
Cany anyone else verify?

My nexus 5 does the same thing .I don't know if it's a bug or it's meant to be like this.My other issue i have with the proximity sensor is that sometimes after a call ended the screen doesn't turn on and i have to use the power button.

Flash always lit?

Anyone else have their flash led always dimly lit? Even when the phone is off my camera flash is dimly lit.

This is most likely the heart rate monitor. There is currently an issue with Google Fit and the S6 which causes the heart rate monitor to stay on. The only solution st this point is to uninstall Google Fit until Google releases an update that fixes the app.

I'm not sure Google Fit is the only possible source for this problem.
I have the same problem as OP. I got my S6 (non-edge, 32GB) about 24 hours ago and last night noticed the faint yellow glow on the back of the unit. I haven't been impressed by the battery life (admittedly a very limited time with it so far) - but this could explain the less than stellar battery life so far.
I don't have Google Fit installed (in fact if I go to the play store, I get a message saying that it's not compatible with this version"). S-Health is disabled too.
One other thing, when I use the flashlight feature, I notice that the light isn't nearly as bright as on the S3 - not sure if this is relevant, it is the same LED.
I rebooted the system, and even turned it off, the faint light stays on. If the unit wasn't sealed I'd pull out the battery just to confirm this light can go out :-/

I have this issue on mine as well. I first noticed it when I went to charge my phone over night next to my bed. I lay the phone on its face so the LED notification doesn't show. I noticed a slight glow from the flash diode. I thought at first it only happened when I was charging my phone. Today, while at work, I powered down my phone and again noticed the light. For me, its always on. I just got off the phone with T-Mobile and they are going to over night me a replacement. I mention this thread to the T-Mobile support rep and she looked it up while I was on the phone with her. My friend's S6 does not have this issue, so not all of them are having this. I encourage everyone to go into a dark room and check your flash diode.

Just dropping into say I also have the issue . 32GB, Standard S6, T-Mobile. I will call them and get a new one overnighted as well.

Sorry to mention this and I don't mean any disrespect but there is a small plastic cover over the camera fnt rhw rate monitor did u peal it off ?? It should be OK now

No disrespect taken, man those are hard to get off (thanks for confirming this, it looked like there were).
However, that might explain the flashlight function being a bit dimmer than on the S3, but it wouldn't explain the constant light source itself.

How can we possibly check this in store where there is substantial amount of light anywhere. I'd definitely check my S6 in store for this.

Mine doesn't have this dim light at all I checked and I closed all the lights to make sure nothing is coming out . I don't know I wish I can help

I think it would be difficult to see unless you ask them to let you into a dark storage room without windows That's how I can verify mine is still doing that during the day, though at night when I wake up with the phone next to me, the glow is comparatively quite substantial.
Plus, you'll have to wait about a week before you can see them in the store.

I have two S6's and can confirm both of mine has this dim lit light only noticeable in the very dark.
The problem with us getting the device early is we don't know if this is hardware or software problem., that might get noticed and fixed with an update. Many say after the actual launch Samsung/Tmobile pushes an update. We can assume they at least will to fix the cell standby draining battery with VOLTE issue. Plus how many will we have to get shipped to us before we get one that doesn't do this, very different than being able to have the associate check it in the back office with lights off.
Can anyone that did get a replacement comment on this.

Mine is doing it too. If it is indeed the case that not all GS6s are doing this, that does make me concerned that somehow my unit is defective. I'm wondering if I should just hold onto it hoping that Samsung will fix it with a software update or if I should try yo exchange it.

I spoke with a tmobile rep. He said online orders get 20 days return exchange from the day of delivery not purchase. He also said there should be an update on a day or two after the official April 10th launch. I told him to document my account that I called about this issue. He said I could get another (two) overnight to me, but there's no way to guarantee if the new ones won't have this.
How come more people are not jumping in here to say theirs is doing it too. If its just us few maybe we do have a problem. But giving it's only noticeable in the dark maybe they haven't seen it on theirs?

I think you are right, unless you have the phone next to you at night you probably won't notice it., still odd, I would have expected others to notice it too. And, even as dim it is, it can't help with battery life. I hope it's a software issue and can be easily patched that way.

Edit: just noticed tonight that my phone does in fact have the LED issue. It's odd because I spent some time yesterday in the dark looking for the problem and it was no where to be found. Been laying in bed messing with my phone while it's charging, decided to flip it over and low and behold, dimly lit flash on :/.

To see if I could get an idea of what it looked like though, I turned on the torch for about 20 seconds, then turned it off and looked again and it did replicate the faint glow that it seems most people are speaking of, however it faded away in about 30 seconds.

This is making me think some S6s just have this defect where the LED never turns off and some don't. I think it might be best just to return my S6 and repurchase the phone after its official release date. I think these earlier phones might be more prone to defects. My gut feeling is that this is something that won't be fixed via software. I don't think exchanging the phone for a new one will help too much given that so many other S6s also have the issue, you have a good chance that the new phone you get will also be defective.

My guess is it's a hardware issue (perhaps they used a different supplier/component for this part) since all of the phones are presumably running the same software (some with the OTA update that was waiting from T-Mobile - like myself, others perhaps without it). If it can be patched with software is another issue.
Actually, perhaps it would be useful to know if those experiencing the problem have applied the OTA update and those without haven't. My hunch is it won't be a factor, but curious, so people reporting should state their situation.
For my non-edge S6 (black 32 GB) I have the OTA and my flash stays on dimly all the time.

I noticed this last night and I thought it could have just been some sort of burn in from using the flashlight. (64gb regular tmo S6)
It's basically impossible to tell with any sort light around whether or not this is happening, even just with residual light, but mine does seem to be dimly lit in a pitch black room.
Could it have something to do with the selfie feature on the camera? Using the heart rate monitor as a picture button, that is.

I have a 64 GB T mobile regular GS6 with the OTA and I do have the issue.

Screen brightness changing when using apps...

When using an app or a game the screen brightness suddenly changing as if I had auto brightness on but it isn't, always seems to go dimmer and sometimes goes to dim and light in quick succession. Is there something in the settings that I need to change?
Samsung S7 I am using.

Same
I have this problem as well, my screen gets brighter some moments.
I notice the colors on the screen become lighter, after a few moments it wil change back to normal.
I don't know what's causing it.

me as well
Yea me too, seams to do it when ever it want not in the app or program.

I'm having the same issue on my S7. Pretty annoying.
Edit: Found a solution here: reddit.com/r/samsung/comments/4a5kkv/when_i_open_certain_games_the_screen_dims_but_the/d0y94nq
You have to install package disabler pro and disable gameservice

It's a feature not a bug.

That does fix it but you don't need to install package disabler pro.
Go to Settings/Applications/Application Manager/More (upper right)/Show System Apps/ then scroll down to "GameService" and disable
I had tried Disabling Auto Brightness, turning off Adaptive Display and Power Saving but turning off GameService finally worked.

thanks
hey thanks alot. i appreciate it. now if i could just get this thing to cool off. thats the mosst disappointing thing about the s7 other than the screen triping out every once in a while, oh and the lag issue, and that they took out the ir function although i much rather have the expandable memory & Micro sd slot, the lack of volume is a disappointment, and the fact that i still haven't received the vr free gift package that t-mobile promised even tho i pre-ordered on the feb. 23 and got the phone like a week later. did i mention how hot this dam thing gets? my s6 got hot a little bit but this is horrible. kinda makes me want my s6 back.

It shouldn't be getting hotter than your s6. Granted it should get slightly warm, but my biggest issue with s6 edge was it would get scorching hot to the point it was uncomfortable. This phone never gets that hot for me. So keep an eye on that, or hand?

Been running into this with my relatively new S7 Edge and the Package Disabler Pro approach with gameservice seems to have done the trick for me, too. Thanks!

This is happening on crazy spammy's note 10 + as well
Got it root'd up but don't see game service when searching for it in titiamum backup

I recently got the same issue on my S10. And couldn't find the game service too. Have you found any solution for this issue?

Note Edge overheating .

Hey guys ! I just recently bought a note edge with known history as it belonged to a friend . It's the international SM- N915F edition which is updated to marshmallow 6.0.1 . Stock original firmware . So the phone I noticed begins heating up with wifi . Just normal use would see the screen warming up and the metal rail and the back . However when the wifi is turned off , it's cool as ice . I checked with mobile data on and still no signs of heat . It heats up with wifi usage .
Did a factory reset , got a new battery , has no rogue apps whatsoever . Help needed as I really need this phone to work and pay off for its price I paid . Cheers .

Perhaps some app is constantly using WiFi or WiFi is continuously scanning for access points
My Note edge always used to get hot (65-70C) with screen on. But underclocking solved my issue, only 45C with screen on.

The one thing I haven't tried is reflashing it . And trying lollipop if that didn't work . I don't think it's a CPU issue as when wifi is off , I could run plenty of apps without the slightest bit of heating up at all .
