Dear developers, I am concerned about the behavior of the LED on the Nexus 5 devices while charging. On other devices with omnirom, when connected to the charger, LED just lit all the time. But on the Nexus 5 with Omnirom LED periodically blinks during charging. On other roms with LED everything is all right - LED continuously lit while device charging.
This is a bug or a special feature of the rom?

Standard Nexus 5 behavior we just haven't gotten around to changing (we've all been spread really thin with way too much to do and too little time). Submissions are always welcome.

Thanks for the answer. Unfortunately, I'm yet not good with the codding for such things. But I can say that the behavior of LED are very well implemented in slimrom. It would be great if someone could port it from there.
Best regards.

I installed the official update. After shutting down, nexus4 can't start up. Press the power button over 10 seconds, it also can't reboot. And I pressed the three buttons, it can't go to the bootloader interface. How can I get it start up again?:angel::angel:
I had this when I did my update. It took a while of holding the power button to get it too boot again, try charging for already an hour then hold the power button for at least 1 min. Once I got mine to boot again I've not had any issues since when booting it up.

Thank you very much, but it still can't turn on.:crying::crying:
Hmm... Do you see red LED light flashing when trying to turn on your device? If not, try charging it for a little and it should boot afterwards.

yes, I saw the LED's red light, it sometimes last 7-8seconds somtimes 1 second.,:crying::crying:but what's that means. It's still doesn't work. I have no idea.
Then you may be out of luck. Take a look at this thread: http://forum.xda-developers.com/showthread.php?t=2011328
You can try leaving the phone on AC charger overnight. Some people have reported that they managed to fix their phones that way.
Was it the official OTA update you installed? I suppose your device was not rooted then.

My phone was on USB charge once ( actually plugged into the computer not the ac to USB issue people have been having) and because it thought it was charging it carried on as normal but the battery wasn't being charged fast enough by the USB to keep it running and the phone just died, no shutting down or anything dead with a flashing red LED the reason it did this was because the os thought it was charging even though it was discharging so until the battery actually ran out of juice the phone ploughed on. I immediately unplugged the USB and switched to the AC. The red light went off and the phone was silent for at least 10 minutes. I then with all toes and fingers crossed tried to start it again and it did. The red led lit up and stayed on for about 5 seconds and then burst into life. It really depends from how long you've had this red led if its been like it for a while I'd recommend a straight 24 ac charge with no interruptions. If that doesn't work I'm out of ideas :/ good luck Blewk

yes, I installed the official OTA, and then my nexus4 turned on once and down, when I tried to turn on again, it displayed the Google logo for a long time, I powered it off and it bricked. My nexus4 was not rooted yeat.

Thank you. I have tried charging my nexus4 for 2-3hours with the USB charge adapter, but it sames like the battery is broken.
I have a question that I wasn't able to find an answer to while searching the forums related to the Nexus 4. Has anyone experienced their Nexus 4 still showing that it's charging (lightning bolt symbol in the battery) even when it's on a 100%? Does this mean it's still charging? If so, is this a possible software issue? Could this be damaging the battery? I'm asking because I leave my phone on the LG Charger overnight so I know it has to be fully charged (considering it's not below 50% ever when I go to bed because I charge it throughout the day). I remember on my previous devices (MyTouch 4G, HTC Sensation, Nexus One) the battery indicator would become a solid color and you would no longer see the lightning bolt symbol inside the battery (also notification light would be green but there isn't one on the Nexus 4).
Note: I'm using Stock and running Android 4.2.2 (this was also occurring on Android 4.2.1) and my bootloader is unlocked.
Thanks in advance
I'm pretty sure that the lightning bolt basically just means that it's connected to a power source of some sort, not that it's still charging as such.
Turn your phone off, then plug in again. When the batter is charging, it doesn't show a full battery image. Doing this just to wipe out your worry because as soon as the batter is full the charging process will be stoped.

As far as I know, the mechanism to stop charging when battery is full is a hardware thing. So I do not think it is damaging your battery.
Go to Settings -> Battery and see if it is saying 'Charging' or just 'Charged' at 100% just to be sure.
is this kind of thing linked with the li-ion batteries this phone uses? this sort of charging behavior never happened on my zte blade or huawei g300

Hello everyone and happy Halloween! I have myself a Nexus 10 running CROM Kitkat v7.1 with KTManta Kernel 3.4.86, bought used off Amazon. A while ago, there was a power surge, and my tablet didn't charge for about 3 hours. I restarted it many times, and finally, it charged. Ever since then, OTG doesn't work, the port doesn't output power anymore, (tested with known working flash drives and hard drives) and the tablet doesn't recognise it is charging for any amount of time from a few seconds to roughly 5 minutes. If I use the tablet while charging for anything other than light internet browsing, or I turn on auto brightness, it stops charging, then stops responding to touch until the charger is unplugged from the tablet. I'm pretty sure the surge fried something, but what? And why does my poor Nexus act so bizarrely while charging?

Hi,
Happy Halloween for you too . Well, I'm sad to tell you, but it seems like a hardware problem. As you said, the tablet didn't want to charge, neither it is able to output power to the OTG anymore. I believe it is was caused by a current peak during the surge. And that probably messed up with your tablet charging port, messing with it is probably sending bad voltages and current on the battery, which can damage it and cause overheating and such as well.
This was my quick diagnostics. I'm not so sure about it, but everything leads to this idea. I'm pretty sure asking you to reflash stock would be useless. But it's worth a try. If the problem is really hardware, then the solution is pretty obvious, and unfortunately hard. Send it to a Samsung costumer care or buy the pieces and try to solve it by yourself.
I'm sorry for your tablet, and wish you can fix it!

Yeah, I was hoping it wouldn't be a hardware issue, but I'll try stock, and if that doesn't work, I'll have to go and see how much it costs to fix it... Thanks! And Touhou is quite fun!

I cannot help with the OTG. For the charging, are you using the micro USB or charging using a pogo cable? If you are not using a pogo cable, you should buy one and try it.
Hi everyone I have note 4 sm-n910h I updated to 5.1.1 my phone gets 100% and the led turns green but doesn't say battery fully Charged before 5.1.1 everything was good .. my question is it just me or all note 4 users
I use stock rom no root
never noticed....but the light turns green only when the battery is fully charged so no problem.

I notice a small bug when charging the phone. When the battery level is at 90% or higher but not at 100%, the phone's LED indicator turns green, as if a battery is fully charged. Did anyone else notice it?

I have noticed, I just assumed it meant the phone was close to 100%. I wouldn't necessarily call it a bug it may be intentional.

On every other smartphone I've owned, the LED turns green when the phone's battery is at full 100 %, not at 90+ %. On my PH-1, the LED turns green at 90+% and then continues to charge until it reaches 100 % and only then I see the status as Charged.
I'm pretty sure that's a stock android thing. I've seen this on other phones, all of which were running custom roms
Yea, this is normal behavior.
Yeah, it's pretty normal on Android. Especially on all of the HTC devices I've owned. It's a good idea not to charge your device to 100% any way, unless you're doing a battery calibration. I make sure to charge at around 20% and then unplug at 80-85% for optimal, long-term use.
Normal behavior. Not a bug. Once root is obtained, you may change this if you wish
Im going to try light manager and see if it will let me manage this. I used to use it on my 6p. but yes to the above. a number of phones i have owned goes green @ 90-95%
It's been a while since I owned a phone with an LED but I noticed this for the first time on this phone. Thought it was pretty cool since I always try to unplug at 90%
I find none of the light apps work very well. Light colours don't match. Also, can't get the lights to blink differently then what they already blink at. I'm not concerned about the colours as I am more interested in changing the blink rate. Would like it up blink faster.
Sony devices turn green at 90% as well. I find that more useful than 100% so was pleased to see that behaviour here.

It would be better to be green at 80% but you can do that with lightflow.
I try never to charge at 100%.
