[Q] Nexus 4 Random Power Off

As the title states. Nexus 4 random power offs. Has anyone seen anything like this?
Here is the background info:
My parents have Nexus 4 phones as do I. All of our phones were ordered at the same time about 2 months or so ago when they became available again. All phones are the 16GB version. All phones bone stock with just OTA updates, not unlocked or rooted other than how they are shipped. All using T-Mobile prepaid plans.
My phone and my father's seem fine. My mom's however seems to shutdown on its own. It is random. Initially I thought that it may be an issue where she isn't used to a smart phone and isn't charging it enough. It happens though at times while it is connected to the charger. It also has happened while carrying it off the charger.
One odd thing is that when they got the phone they brought them to my house and dropped them off to have me set them up. One had the plastic screen protector with the printing on it from the factory the other didn't. I don't know which is which though now. It is a 50/50 shot if this is the one.
I have been around android since the G1 days and run the same phone. I can't think of a setting on the phone that would power it down at a certain time or period of time. She really doesn't have much for apps and is a very light user.
Not sure what to try but I was thinking about doing a wipe of the phone to see if it helps.
Anyone else have any ideas? If the wipe doesn't help the only other thing I can think of is that there is a physical issue with the phone.
I haven't seen this on my phone but there was a period of time where HD Widgets on my N7 would cause a reboot. That was fixed with an app update. This isn't a case where the device reboots. It is a complete shutdown which I find odd. So I have seen an app cause issues kind of like this. For the most part the apps that she has on her phone, I also have on mine. Well I have way more but there really isn't anything on her phone that I am not also running.
I should add that she has the phone in a TPU case. As we all do. My case design is a little different than theirs but they have cutouts for the buttons. So it isn't a case where the case is pressing on the power button. That could be an issue with my case as it covers the power button but I haven't had that issue.
Thanks

Sounds like it might be a defective battery...

That is what I am kind of thinking. Either the battery or the smart battery chips. I think I will try a wipe first but like I said but it is odd.

That sounds kind of questionable (fishy) to me... I also have the 16GB version, and I also did the OTA when I got it. But to be honest the stock OS lasted only about an hour before I rooted and started trying out custom ROMs I have not had the issue you're describing though. How are the results from your factory reset?
Also, would you consider putting on a stock-based custom ROM (such as rasbean vanilla) for your mother's phone? If the problem is software based then a reset or a new ROM might yield different results. But if the problem persists it might be hardware and I'd suggest you contact Google about servicing.

I don't want to root and have my mom run a modified ROM. They live about a half hour from me so I haven't tried a wipe of the phone yet and because of the distance I don't want to deal with the issues that sometimes come up when you go with modified ROMs when I am not there. She is a very basic user and this is the first smartphone for my father and mother. Keep in mind they are in their early 70s and not really that strong on the tech side of things. I have to get some time to run over there and take a look at it. Maybe later next week.
I was just wondering if anyone else has had this issue. I think if a wipe doesn't help I will talk to Google. A search really didn't show much other than some people that were seeing a random reboot issue. I have seen apps doing that.
I have been through their warranty replacement process and it is a bit of a PITA. I am on my 3rd Nexus 7 due to hardware issues with the first 2. My N4 and my fathers have been rock solid.
While I have run custom ROMs in the past, I usually run stock until I find a need that requires me to root. Eventually I will probably root and go with a custom ROM on my N4 but

Yeah, I know what you mean. I'm giving my parents my old LG P990 phone and I just put an AOKP rom on it. I also installed Nova Launcher for them and configured it so there's just one texting app and one calling app the one and only one homescreen. No dock either, just in case they click something by accident or get lost in the app drawer
Since you have the same phone as your mom, a self-less workaround would just be to give her yours (pre-configured), and then you can fiddle around with the problematic one until you find a decent solution. :good:

Hmm. That is a good idea. The PITA part would be to get everything loaded from my phone to hers. I really wish I could run Titanium backup without root as it would make it super easy to move the apps over. Though I don't have that much loaded on my phone. Things that are a pain to set up have configuration export methods like Tasker. It would rule out the end user being the source of the issue. I don't think that is it though. If we swap and it goes away, then I can consider the wipe as the solution. If the problem moves to me then it is a physical issue and call Google. If the problem persists with her, I load all her apps on the phone I carry as well to see if I start to have the issue or it becomes a training issue. The thing I like about this the most is that it is a clear process to rule out several things. I can go over there and sit with the phone but if it doesn't power off when I am there I don't gain much other than spending some time with my parents.
I don't think this is an issue but I did have to provide my IMEI# when doing the activations. In the past though on T-Mobile I have handed phones down to others and all we did was a SIM swap. I would imagine that is the case here.
Oh and one thing I did leave out. They were using their old cell phone chargers on the N4 phones. I told them to swap chargers and use the ones that came with the phone. The old ones may not put out enough power and the phone could in theory run down to the point where it shuts off and slowly charge from that point and I don't think it would turn back on. Keep in mind a retired user who just had a knee replacement so she is at home more often than not.

Did you find out the cause? I have the same issue happened twice today

The random shut off either charging or not happens to me but as mentioned before in a related thread, a lot of the times it also happens on Wi-Fi, and having WiFi optimization on.. purple were turning that off and some fixed the issues. This is my second nexus 4, so I right id give it a try and not use wifi and hasn't happen since I received mines on the 4th of may

So you're saying it's a software issue?

Looks like it.. Turning off optimization or not even using WiFi at all worked..

[Q] LG G2 Battery/CPU Overheating During Miracast with Streaming Video

Edited 2/11/2014. I am running Sprint ZVA, stock. Removed "sprint variant" from title due to a tmobile report as well of same issue.
Have found a problem with my G2 that only seems to occur when running miracast. I recently purchased the tronsmart t1000 to miracast from my G2 5o my Sony bravia tv. Now the tronsmart runs the Ezcast app available from the Google play store.
When activating miracast you use the ezcast app. However once connected you can exit from the app. It does not run in the background. The miracast service is on, wifi remains on but the phone data connection is what is being used. Everything is fine but when I run a video app be it Netflix, crackle, or any other my phone (via battery monitor) reaches 48°C within about 10-15 minutes of streaming. Video performance begins to suffer at that point and lags, stutters, etc.
I have disabled every background service I can think of. No syncs, no gps or location services on. I am running stock zv9, bebloated (frozen via titanium), rooted. I had the same issue on zv8. I have also used the screen off app to eliminate extra heat from the screen being on during casting.
I will note that I had this same problem before I even rooted my phone and debloated it on the stock zv8 rom.
I have contacted the ezcast folks in china but they say their tests with G2 do not overheat although they cant test netflix and the like because of being in a different country. I contacted netflix to see if I could report the problem and they acted like useless tools. One rep even told me that LG writes the netflix app so I need to report it to LG... lmao.
So, Im turning to xda to see if maybe others have this problem or know of a fix. Im glad to provide what info I can if it hasnt already been covered. In my research Ive found the thermal throttling doesnt kick in and sut down the phone till about 55°c or so. Im certain the phone is getting close enuff to 50°c that I need to be concerned about long term damage to my G2 if this continues.
Ill add that even during dlna streaming the phone is getting hot but not as bad as miracasting. The phone also gets up around 45°c when using a slimport. I really would like to figure this out. I do have best buy return coverage for my phone but would like to avoid swapping it and having to pay $150 to do so.
Does anyone have this problem or know how to correct it?

Well if it's the CPU then don't worry that much. 55 degrees is a safe operating temperature. If it's the battery temperature then you're ****ed, so I'm quite sure it's the CPU temperature .
You don't really have many options other than cooling down your phone while miracasting using a fan or whatever you have avaliable. As for the lagging/stuttering it's because the phone starts throttling down in order to avoid very high temperatures. If you cool down your phone, the lag would go away but you can also disable thermal throttling from the hidden menu (which will cause your CPU temperature to skyrocket).

Im using batt monitor widget. It said 50°c last night on a second go around with absolutely every background service stopped. If I was to disable that throttle via hidden menu, then my phone would surely fry. So I appreciate the idea, and read that whole thread before I posted here, but its probably not adviseable for my situation to let the phone get hotter than it is now.
Edit on my first post. I did mean Im on ZVA now, not zv9. It was a late night last night. lol.

Well I wrote to LG tech support outlining my issue. Havent heard back. I did try to run my wife's htc one with my miracast setup. While streaming her netflix via miracast the phone reached 40°C and was stuttering a bit, but it didnt get any hotter. I let her htc one cool down and launced crackle, and hulu plus and her phone never went over 37.9°C.
Leads me to believe that this is caused by a couple of factors. Maybe something in the netflix app in combination with the G2's miracast functionality. All I know is that netflix streams hotter, but other video apps run almost as hot on my G2.
I could really use some advice from a battery or cpu guru cause Im at a loss here.

Since you're rooted why don't you throw a kernel with kernel tuner and knock the processor clock speed down while you're streaming. I know you shouldn't have to, but you may need to. Running it at say 1.2 - 1.5 ghz should still run fine and keep it cooler.

I could certainly try but Ive never implemented anything like that before. Not quite sure I have enough knowledge. Is there a resource in plain english that a beginner on that road would understand?
Id rather not have to go that route. I usually stick mostly to stock except for a few tweaks here and there. Im not opposed to learning tho.
Im suprised Im the only one this is happening to. There must be others miracasting netflix and such. I was hoping for a simple fix. I dont think Ill have such luck.

I miracast to my vizio stock(only rooted) to stock (tv), no third party hardware or software, no high heat...

Thanks steamer. Im really starting to think Im alone here. Guess Ill have to figure out if it software related. My project in a few days will likely be running a .tot. Heard back from LG. They suggest sending phone in for warranty repair. However I do have geeksquad coverage thru best buy so I may go that route. If it still overheats after reverting back to factory stock then I know its hardware related and will be able to hand my phone over for warranty.
I did get my phone the day it came out. Maybe I got a lemon.

Can I get some opinions/thoughts on wether the furnace kernel by savoca or dorimanx kernel would possibly help my situation or make it worse?

This happened to me on my t mobile g2 the first hour I powered it on it was roasting my hand but when I went to settings and viewed what's draining the battery it was Bloatwear. So I rooted and used titanium backup to defeat them. A neat app to view what's running is memory booster then I Google search safe Bloatwear to delete and if it's OK I get rid of it. My T-Mobile g2 got glitch tho but when I got the d802 international version with no T-Mobile Bloatwear it didn't heat up at all

Thanks, but Ive been there already. I use titanium and have froze all the bloatware. It makes no difference. I think im gonna try a .tot. I cant seem to get much help on this.

Well another update, kinda feel like Im talking to myself here... lol.
Restored to factory zv7 by doing a .tot and stayed unrooted without making any modifications. Pure Sprint G2. Downloaded the ezcast app and netflix only. Tried to miracast and phone still overheated. So now I know its gotta be either the ezcast software for the tronsmart dongle, netflix app, some kind of wifi bug, or a hardware issue.
Gonna leave the phone as is and head to bestbuy tomorrow and see about a warranty replacement. Only thing I can think of is I got one of those G2 that had thermal issues on release day. I know I heard more than a few reports back then but didnt think I had a problem. Not till now anyways.
If anyone has any other ideas tho please chime in. Ill update again if I get a new G2. We shall see.

You aren't alone!! I just purchased a G2 from T Mobile last week & had exactly the same problem. I am using a Netgear P2TV3000 receiver. I've found that the phone heats up while connected via Miracast if I'm using other apps, just not as bad as it does w/ Netflix. I emailed LG about the problem & they said it was not a known issue & suggested taking it back to T Mobile. I did that yesterday & they gave me a new one. I took it home & tested it out...same problem. So I've given up & will be taking it back to return it for a completely different phone, probably a Galaxy S4. I'm really disappointed bec I really liked this phone. But Miracast not working properly is a deal-breaker for me.

Glad to see Im not alone and its not just a sprint variant issue. Thanks for your post. Actually at best buy now and they are still deciding what 5o so. Their cell expert hasnt got a clue either. Everything he thought of I was like... been there done that.
Edit: That was a useless exercise in futility. Bestbuy said their service center would likely send the phone back to me.saying that this overheating is within normal operation.... HOW? Cause their people will not take the the time to actually test the miracasting. So Im stuck dealing with LG and a warranty replacement, if they will even do anything.
Please, anyone with miracast dongles... would you check and see if you can recreate my problem? Simply stream netflix via miracast via your mobile connection. Not wifi. Thanks if you are willing to test. Within about 15-20 mins you should see your temp spike. 30 mins in you will be near 48-50°c.
Id like to see if this is a more common issue.

What version of Android are you running? Both phones I've had this problem with were running 4.2.2. I've talked to several people who have no problems like this but they're running 4.3. It makes me think 4.2.2 is the culprit. Tell me you're running 4.2.2!

Well stock lg g2 is 4.2.2 so yes.

Mine got hot enough charging + miracast netflix that it began to heavily stutter and slow to a complete stop. I didn't realize how hot it was until I picked it up to close netflix. It was throttling enough that I had to restart the phone just to do anything.

Thats pretty much the exact behavior I have seen. Did you happen to check the battery temp? Which carrier are you on?

Unfortunately I didn't get to check them. By then, my phone was lagging so bad, all I could do was restart. By the time it restarted and I got a battery temp monitor downloaded, it was at 44. I'm on AT&T. Stock rooted rom.

Were you using a dongle as well? Seems casting from phone to a device like a tv with miracast built in may not cause issues but Im not certain of that yet.
Im wondering if the impending kit kat update will eliminate this problem. I have a repair auth from LG right now, but Ive been holding off sending my phone in. LG says this is not a known issue. Id advise anyone that does have this overheating issue though to report it to LG.

IS it worth Rooting ?

I just bought a Sprint V20 and so far I have been looking through the roms and non are without bugs or problems. Which rom would you guys use and is it really that much better to root the phone over stock ?

Mine was lagging horribly and the battery was draining really fast.
I rooted and it has been so much better.
DevDigital's Sprint roms have been flawless for me. Not a single hiccup.
Just don't factory reset within twrp or you'll end up in a bootloop. Not bricked but aggravating.

I've had mine since Black Friday and still haven't rooted. I'm enjoying the phone despite the lack of data tethering. Is there a way to set the wide angle camera as the default camera so that 3rd party apps use the wide angle rear camera instead of the current primary? I'd enjoy the phone that much more if that were possible.

For me it's worth it just for adaway.

There is no way. At least for Tmobile's variant. However, it only take a second to either zoom out or just click the icon and it will both take you to widescreen. I find zooming out easier for me. I dont know why

I personally only root to control programs that we should be able to control anyway (aka facebook), I get annoyed at how programs continually relaunch themselves without my knowledge.
That being said at this time I haven't rooted mainly because I've only had the phone for a month and I want to make sure that the phone works properly for at least 6 months.
Right now I am running greenify to attempt to control apps that think my personal phone is their playground to do whatever they want.
If I was younger and not dependent on my phone for a lot of things (business and organization) I would try other builds people have made but since I need reliability above all I personally tend to stick to stock builds.

I may try this soon. I just hope DevDigitals Sprint roms are stable. I use Black Player as my music player for the gym and the camera is awesome for my Cruise I'm taking in April.

It still looks like people are having issues with DevDigitals rom. The data and texting issues. Are all these issues solved in V6.5 ? I use my phone for work and cant take the chance of it not answering a call or a text. Is the new V6.5 working as a daily driver for Sprint users ?

no issues at all on 6.5 for most.....
people sometimes don't read/search anymore

I did post once that I was having data issues but it was no fault of DevDigitl's great rom.
It was my wifi wasn't shutting off and I had previously signed into xfinity wifi. Every time I got anywhere near an xfinity wireless connection, (which is every other house in Boston) it would try to connect.
I'm still learning LG. Been on Samsung for a long time.
I firmly believe the rare connection issues are user error. Once the rom is installed you just need to click update profile and then update prl once.

It's worth rooting
Settings/Developer Options/Tick on "Force GPU Rendering" this should make this beast smoother/snappier" If root available try L Speed/Entropy/fstrim apps found on Play Store! LG V20 & LG G5 are snappy beasts, well optimised with Snapdragon 820 and is better than Samsung.

my LG-V20 was also laggy and draining battery quickly. i finally rooted my phone and it is 100% better i am currently using Maximum OvrDriVE Rom. its extremely nice. so if anyone else has the lag/battery drain quicker i suggest rooting your phone should fix. its been about 2 weeks and still doing great also so.

If you want a stable amazing ROM the NotSoStock ROM is the only option....
Don't hesitate just do it. You won't regret it.

Screen ghosting

I have a v20 h918 running super v20. On the latest update (4.0) im experiencing ghosting on the screen (looks like burn-in but isn't permanent). I'm asking about this issue in general because it isn't an issue specifically related to this rom, but an issue I've seen reported on completely stock Tom's too. I believe it fades to a degree while the phone is still powered on, but a reboot clears it right up. I've seen the people trying to insist it being a hardware issue, but in all cases I've seen, it's been experienced after an update (stock or otherwise). This ghosting occurs after still images are on the screen from 30 seconds to a couple of minutes at most, not the time to cause any real burn-in. I'm just trying to find some real answers from others who have experienced it, not someone taking guesses. It's not hardware related. Its appearance coincides with software updates, and its appearance isn't permanent. But it is annoying as hell. Any help?

Ive tried adjusting screen settings, but it really makes no difference. I can achieve the same amount of improvement but just keeping the brightness minimized. As for it being an issue with the phone itself, I beg to differ. This is the lazy man's answer. It doesn't conform with the fact that it seems to appear with software updates instantly. That's not indicative of a hardware issue. I've never seen it before until immediately after a software update. This isn't a minor problem that got worse, it's an issue which appears instantly, and isn't permanent like burn-in. This is partial retention of previous images on screen which has to be software related because a reboot will remove all signs of it from the screen. I've used my phone at full brightness for extended periods and have never had any sign of this.

Ive tried adjusting screen settings, but it really makes no difference. I can achieve the same amount of improvement but just keeping the brightness minimized. As for it being an issue with the phone itself, I beg to differ. This is the lazy man's answer. It doesn't conform with the fact that it seems to appear with software updates instantly.

First complaining here about it isn't going to fix it you need to be going to the source.. LG. I simply stated what has been known since the release of the phone and the best resolution agreed on as the best fix by the majority on this forum. My response wasn't lazy, it was reality. Using kcal to set screen settings values I have never seen ghosting or retention on my phone. Therefore you have been given the fix twice now if you don't like it, then take your issue up with LG

it is permanent burn in...

Its LG's trash "ips quantum dot" tech. The screen in this phone (display and touch hardware) is a complete poop show.

Anyone else simply happy not rooting this phone?

When I bought this phone two weeks ago I was excited at the prospect of rooting it so that I could install my "goto" root apps.
I pondered it for several days and was about to root yet another device and I changed my mind. I find I am enjoying Oreo just the way it is and for me this is a nice change. I tend to root/jailbreak everything immediately. In the end flashing rom updates and fixes actually started to give me anxiety. I found myself dreading updates and it was becoming a real chore and wasn't fun anymore.
Anyone else enjoy this phone without tinkering with or modifying it?

Yep same here, been having this from last year and half, the verizon variant.. Though rooting this is pain and all but just like you I was too. Much into rooting and flashing.
This phone as it is, is awesome enough.
But i liked nougot more

It is an amazing device. The only reason I rooted it was to remove the screen retention with a custom kernel and ckal support. :good:

One thing, is there any way to increase refresh rate without rooting? Just thought about this for some reason.

With Oreo I do not feel the need for root anymore.
On Nougat I used root for KCAL, build.prop mods for 16bit.pcm.offloading & zero shutter lag and also mods for stereo speakers & no throttle.
But I've yet to come across any burn in on Oreo, maybe they fixed it by recalculating the default KCAL values?
They've also fixed the issue of 44.1Khz audio being output as 48Khz through the DAC.
Could also be placebo but I find the DAC to perform better now on Oreo.
I'd love to have zero shutter lag & stereo speakers but that's just a mild annoyance hardly anything to worry about.
The weird thing is that my performance have seeming increased going to Oreo from having the performance mods on Nougat.
The left picture is on Nougat and the other one on Oreo.

Now that I think about it, silent camera would be nice for the default camera. If the setting is there I can't find it. Thanks for the side by side. Interesting.

Yeah, I don't need to root this thing either. I have had this almost a year now. Upgrade to Oreo, and now happier then ever.
May be in future once we Pie ROM with second screen feature, I will think about it.
I used to have a Samsung Note 5, and rooted and flash plenty of times. But, it was a pain to keep up with updates. I learned my lesson to not root Android.

I imagine this is how most get out of the rooting game.
There has to be a serious need to do so and not just for the sake of it.
Though i still believe unless you gain admin rights over your device you do not own it.

First time not rooting in about 10 years, running Oreo and so far everything is good (battery life, performance, features). I haven't even re-installed Nova Launcher, the home with app drawer has been good enough.
The one thing I'm missing is forcing it to 3g/CDMA since I'm on Verizon and where we live in Colorado, there is more and stronger 3g towers than LTE so I've always saved a lot of battery by locking to CDMA and not hunting/swapping for LTE towers. I'm mostly at home so I've got wifi for any real data needs. So other than that one thing, I haven't had a real need to root. So far...

If you have your msl you can force 3g or you can install Xposed and I think there's a module for that. Inteli3g

This is the first time I've rooted a phone for a while, due to the screen retention issue. Else, stock or AOSP unrooted is enough considering most features are available these days

Thanks for replying, I've been trying to get into the field service menu for the last couple of days but will probably have to call VZW and try to convince them to give it to me.
Re: Xposed, since that requires root, that was the one reason I miss having root (Xposed to be able to force 3g, that's how I did it on my old rooted phones).

That wasn't my experience with Oreo on my H918. Perhaps I need to try it again. As I recall, I still had screen retention issues, which is what ultimately led me to rooting my phone to use KCAL. I would really like for this phone to NOT be rooted.

Close to two months after my quoted message I can tell you that my phone do indeed suffer from screen retention. The first month i.e up to sometime in February I did not notice any screen retention - but since having sold my computer and using my phone for much more it has started to reveal itself.
It's only visible in one app, and that's Discord with its dark gray background and the 'retention' is that of the keyboard close to the edge of the screen.
Considering the circumstance around my screen retention, that for now, my V20 is my main 'machine'. I'm not that bothered by it, I have a PC coming in next week - and if I remember I'll tune in some weeks after it has arrived and update whether or not it's gone(with decreased usage).

For me I had had enough with screen burn and rooted this phone in last December.

Yeah, I realized I dug up an old post. Sorry about that.
I may have to try running my phone in a stock form to see how bad it really is. I'm running into some weird issues with, presumably with Magisk, and I want to unroot my phone. The only real reason I can't is because of the screen retention issue.

Oh it's no problem, sorry if my post came off as offensive.
It is really not bad at all, and I might elaborate om the issue that it's only really beginning to show later in the day.

See, mine will show retention minutes after being booted. For example, after a fresh install of a ROM, be it LOS or Stock, I'll start noticing ghosting before I can get into the color settings or Kernel Adiutor to make the adjustments... that's just from the time in TWRP and the booting. I guess everyone's phone it a little different.
