arc reboots

Guys i know this is a repeat problem but i really need an answe for this!
my arc suddenly decides to reboot and then i pick it up and shake it a little hard or tap the back cover or give it some kinda jerk (not hard) it keeps rebooting, then i let it be for a while and try the same tapping or jerking but then it doesnt reboot no matter how hard i hit or tap the back cover.
Do u all think this is a hardware problem ?
The battery is very tightly in its bay
is anyone else having same issues ?
thanks

I had the exact same problem and it has actually seemed to stopped recently. Last week it rebooted about 5 times in one day. This week, one reboot in 7 days. I still haven't found an answer. Just going to wait and monitor.

I noticed this too, happened while I was jogging (using Google's My Tacks), and once when I picked it up quickly. I don't think it's a battery fit issue, i think it may have something to do with the accelorometer or something. But it is very disconcerting - What if it shuts down at night while I'm sleeping, or the moment I put my phone down to go to sleep? Then no alarm in the morning...

I noticed the same issue, most likely, when RAM is running low. Not as often as you guys though. Twice it was with apps involving GPS and maps (my tracks, locus) once with Mort Player, I don't remember the couple other times.

Yes, it does require reboot, I notice that;
when
3G + GPS use together
OR
wifi + bluetooth use together
ARC has a lot of RAM, unlikely low RAM issues (which happen to X10 mini).
Again, it is mostly likely due to battery usage issues, when you feel your phone hot or over warm, most likely you need a clean restart.

Mine does this too. I'm pretty sure it's a hardware problem, because as it reboots, I can shake it again and it reboots again. Since it hasn't booted up yet, it can't be a accelerometer issue. I think it's just bad hardware design or crappy manufacturing.
I have to say, I didn't expect something this bad from SE. This is ridiculous.

Hi guys!
I have the same problem, i'm turn on crazy, when i shake the phone, this reboot... Any fix for this?
Sorry for my english, i'm spanish.

Clean connectors. I'm sure it will work.

Do you all OC your phones ? Ive noticed a great deal of heat generation when my wifi, or 3g and GPS are on together. i wonder if perhaps its close to the edge so to speak and the extra current being pulled or heat just pushed it over the edge ?

I don't think you guys are having over heating issues. I can play youtube on 3g in direct sunlight for hours without reboot happen. I would clean your connectors. Clean the cache and if your having ram issues try supercharge script. Other than this I would say hardware issue. Try securing the battery down with your fingers and attempt to knock it into reboot.
Good luck...

Hi, we have 4 arc in home, after upgrading to stock ics, 2 have reboot issues, i tryed to use one of then without the microsd card an seem to be solved, consider may be a sd card problem, sorry for my english im spanish, ejem.... kings of Europe and world!! jeje.

Interesting maby your sd card has bad files after update or flash. Try formatting your sd card and see what happens.

I have the same problem on my arc and arc s running stock ICS and use to have the same problem on GB back when my arc was new but was fixed after it's first ever update so I believe it to just be the firmware .

I would suggest holding the top and bottom of the phone and then flexing it in opposite directions. If it reboots then it's got the same issue as my girlfriends Arc (which I am responsible for updating )
Check the attached picture and you will see how I solved it (by reading other peoples reports on the same issue when it was new).
Bottom line, it's a bad back casing design which allows the battery to jump just a tiny bit loose and power cycle the phone in some conditions.

Overheating

This thing gets hot! Just been configuring launcher pro which took around 5 minutes and wasn't data intensive and the back of the phone is really hot. So much that I can smell the plastic heating up! The battery drained real fast during the process too.
Anyone else experiencing this ?

Well that doesn't sound good! I haven't had anything like that. Have you checked the power intake?

Mine got really hot the first day I used it (27/4)...I was just checking out features and installing a few apps. I rebooted it after the battery was fully charged and it's been fine ever since.

I have the exact same problem, it happens especially when I play any games or intensive appliaction. The battery drains and it gets hot next to the camera, I suspect this is where the cpu lives. Do you think its because its rooted? because I rooted it as soon as I got it so I dont know what it was like before.
And as I am away from the uk for the next six weeks I cant even send it back to O2

No nothing to do with root, mine was same before and after, pretty normal to get hot on some demanding apps.

And i thought i was alone...
It gets really hot sometimes though, not to the extent of burnt plastic smell but it gets pretty uncomfortable touching around lens at the back.

I've been going through this this morning. It seems that the CPU loves to go up to 1.2GHz even if it doesn't need to be that high (and it stays there). Also there I've also been noticing through ADB shell that their are a few niggles. For example the wi-fi sharing process can start without even being activated.
For example this was a ADB shell top taken while running Cordy downclocked to 800MHz in setcpu. The phone was a tiny bit warm but only by the camera (where the CPU is). Basically, this just shows that if you are playing a game, nothing else is going on so the CPU shouldn't be going up to 1200MHz. And it plays the same as when it isn't underclocked.
I'm currently assisting Pulser with investigating this until he gets his SGS2.

My phone gets very hot at time too...
I also noticed wifi sharing starting up by itself. Yesterday it started by itself and used 10% battery usage even though I had wifi switched off the entire time..

Do you have root and Titanium/MyBackup Pro?
If you do, freeze anything that mentions wifi sharing, unless you are going to use wifi hotspot and kies air a lot.

My phone got so hot that it shut itself down!
since that i have done a complete reset of the phone and started from scratch again....100% better.
The problem as i see it is with all the 'tinkering' that we users do. All the additional launchers etc and widgets that you add really seem to mess the phone up!
My advice is keep the phone as samsung intended it...or at least change very little. You will see far improved battery life and none of the over heating problems.
Just my opinion but its worked for me.

Find the nearest Apple store near you.

The only time i had this was when it waa both charging, in a case and playing a big game...
Im currently chatting, listening to a live stream, charging and posting this, no problem with heat at all..
Perhaps its a problem with some specific phones

that's just not true.
Mine gets hot aswell .. it's random sometimes but usualy with playing games etc. I suspect it has something to do with the samsung drivers/software and not our tinkering.
Bugs bugs bugs...

Mine also gets fairly hot, which might be a little uncomfortable - but that's the sacrifice you make when you get such a high powered device in such a small space.

Well,amount of apps/tinkering/etc has nothing to do with the phone getting got UNLESS an installed app in messing something up.I have heard many such cases when a rogue app made the CPU run at 100% in different phones.If that's the case you have to find and remove the app.I'd suggest OS monitor for finding it.Never happened to me though!
What's more,it's normal for it to get more hot than your average phone,as it carries more power under the hood and has nothing to help it dissipate the generated heat,as it's plastic.The Desire HD does a very good job with managing heat and I have never exceeded 40 C,even when gaming with an overclock at 1.8GHz and performance governor.Not saying the DHD is better,but Samsung wouldn't have left something like this if it would damage the phone.So I tend to believe that it's designed to get hot.

Mine has overheated twice.
Both times, when trying to pair itself automatically to my car kit. The phone got really really hot (i noticed it warming my leg in my jeans pocket) and needed the battery pulling out to reset it. When it started back up, the running temp was nearly 50 degrees (in standby, it runs at about 27)
Hasn't done it since though, just keeping my eye on it!

The truth about the common overheating problem and/or battery drain.

Many people have had this issue and i am going to put down the facts here.
The GMS radio in the x10 is not.. great.
It suffers in low signal area's lets say 1 to 2 bars of signal or lets say about -80 to -108dB and lower.
It requires alot more juice from the battery and that causes overheating then after a time chipset death.
This is all based on tests done at home.. i contacted my provider and had a petition signed, they fixed the tower and the issue's with my phone's heat are gone!
Now that i have full signal strength the device has no heat or battery issue's at home.
The other problem you can face is only if you flash firmware with a baseband or a separate baseband.
Many times the baseband may not settle correctly.. this will lead to severe heat, restarts, laggs or even chipset death.
Sometimes the baseband will not even be compatible.
#edit
the third problem that i am adding here and almost forgot about...
Charging while under any or even both of these conditions... can be catastrophic.
As sometimes the modem uses so much energy while the INTERNET is in usage that it cannot hold the charge.
There by cuasing major heat.. and you can guess where that will end up.
Switching to 2G instead of 3G can help ALOT, but in some cases this will end badly
As you will get very slow speeds and that causes downloads to be pathetic slow
and even more prone to bad downloads due to the bad signal quality.
The other case may be that you have the dreaded chipset of DEATH if you get above 45*C it's a good chance you have this horrid chipset.
Have it replaced by SE.
#edit END
All of my theories have been properly tested and recreated and fixed to ensure that this info is correct.
Before you call me insane or retarded... test it first!!!

You may very well be right on the issue of the GSM radio but..... Some earlier X10's were a lot more susceptible to this issue. My first X10 burned out in about 3 months and ran warm all the time, but in standby the replacement rarely gets warm unless I'm in a fringe area that only has edge coverage.
Anyway you don't know what a hot phone is until you've used the HTC Dream. At times you can almost cook eggs on it

So true, but i have been seeing more and more reports of this issue.
And would like to simply give a solid answer to this.
This was not meant as a complaint, but more as a answer so as to end the scourge of that question once and for all.
A overheat that ends in a damaged device = a serious issue.

No worries here
I bought my x10 in march 2010, about a week or 2 after it become available in my country. And I must say that I never had any problems with it, except what all experienced with 1.6 version (slow, laggy, few small bugs).
Overheating was not an issue, even when I upgraded to 2.1 and recently to TripNMiUI (awesome rom btw). Only time I had problems was when I searched for the right rom flashed the wrong file and almost messed up my device.
The battery was above 40°C and went to 10% in like 3 hours Now about that GMS thing... at work I have almost all the time 2 bars of signal (see attachment, was at work from 5am to 2pm) the red bar is 1, orange 2, yellow 3....
and blue lines you see is when its scanning. Sometimes I lose signal for maybe 1 or 2 hours (and that sux) But I cant show you phone temp (dont know how), but it is almost never above 30°C , except when I play games and I do quite a lot
So after more than a year I still have original battery and lasts for 3 days tops, but usually its around day and a half. And I love my X10

It depends.. the heat is mostly created from using the GSM radio in these conditions. such as online usage.
Games are not the problem unless they make constant heavy use of the internet.
Also what was the ambient temperature when you are testing?

Well I do play cestos, and was playing pocket legends, both require constant internet connection. But the temperature still didn't go above 35 (was quite warm). You mean rom testing? I mostly try out the nearly finished roms, so never had any issues with rom functionality or temperature. Except when I tried z's alpha kernel. Then it was around 33-38°C. Now that I think about it when I'm flashing new rom it always goes above 30, but after some time drops down.

Yeah thats the BB settling in nicely.. sometimes a few restarts or even the "white led of WTF crash" seems to sort it out.
averagely my phone will idle at 30 to 35*C but in usage it can climb above 40*c often.
My old motherboard reached a record High of 57*C just playing "robo defence" or even Hawx...
But here's one more test for you.
Once you need to charge plug it in and start using the internet for about 20 mins in a low signal area and watch that battery drain and the heat go thru the roof.

I never had this issue and i only get 1 to 2 bars only and it never went above 34 which is cool. Dunno about u guys but the only way i can overheat the phone is when playing heavy gunner and listening to music at the same time and the battery heat reaches 38 and it still works 100% with no trouble.

That's the same conclusion I came to.

But it still has a effect on the phone.
But how many of us still flash roms or basebands?
Some versions of the board are way more unstable.. to be honest you have the most stable x10 i have seen out of the 13 i have seen here around me.
Also.. did you do the charging stress test?
It's more than just a single simple issue such as heat, it effects the battery life. "when the radio has to boost the signal"
And to be honest out of all of my phone this is the only one that loves to often drop my calls in bad conditions.

noob question coming: how do u do charging stress test? is this something like you test how long the battery lasts?

I posted it earlier.. lol. no problem.
Just go to a area with bad signal "low as in 1 to 2 bars", wait till the battery is getting low.
Start charging it and then use the "market or anything that constantly uses the radio and cpu" constantly for about 20mins while charging.
Watch the heat go up and the battery go down.
Also please note that if the ambient heat is very low then your phone should be reading much lower..
Not all of us get snow on this planet, some of us get heat stroke in the winter.

will try at work tomorrow, since i always get bad signal there.

Killed my S2..

I have managed to kill my S2 by playing far too much Hot Springs Story (great game!)
While playing (we're talking a good couple/few hours), I noticed that even though when the phone is connected to the supplied charger, the handset requires more current than this is able to provide, and still discharges the battery (albeit, much slower).
I got a couple of 'battery temperature too high or too low, charging has been paused' while playing, as the phone was sat on my desk, I thought nothing of it.
The next morning I saw the handset had the same battery warning on screen, and was almost completely discharged (although the handset was still on). I knew something was not right then.. The phone was very hot in the casing to the right of the battery (when looking at it from the back). I guess this is where the charging circuit is, but I really dont know.
I couldnt get the battery to charge any more than a few seconds, either when the phone was booted into Android or in its off state. I managed to reload stock KE7 (which was already installed) just to see if it made a difference, it didn't :-/
The phone then refused to co-operate with the battery at all, and simply displayed a yellow exclamation mark next to the empty battery graphic on screen.
I bought a new spare battery of ebay, hoping that the intense discharge/recharge cycle had just wrecked the original battery, but unfortunately the replacement only charged for ~5-10minutes before showing the same yellow exclamation mark :-/ I guess its the charging circuity thats failed.
The handset was from O2 on PAYG, I debranded it by putting stock KE7 on it, and a few counts on the custom kernel flash counter, I'm hoping I can warranty it without too much hassle, but I am a bit anxious that technically O2/Samsung dont have to honour the warranty.. I'll let people know how it goes..
Missing my handset!

hmm, that sucks. so it does really overheat when charging... wow, that sucks a lot! normally when the battery is full, it stops charging and the temperature returns to normal, even though it is connected to the charger.
i guess the same could potentially happen while on a trip and charging/consuming battery using satnav, or listening to music.
not good.

Nothing you did (except rooting) is extraordinary use. They promote its use for games and that's what you were doing. I'm guessing Samsung Tech will probably just replace the phone rather than try and repair it. Good luck.

i got my phone about 1 week ago and only charged it about 6 - 7 times since i got.
Well on my second charge the battery was on zero phone turned off so i connect it to the wall charger and i got the yellow exclamation mark!!!! took the battery off put it back on and it started charging.
And just than on my 7-8th charge my phone was out of battery off so i decided to charge it off my laptop and i connect it to see i get the yellow exclamation mark again while phone is off. But this time i took the battery off put it back in wouldn't work. So i kept trying it after about 5 mins of connecting disconnecting the cable i managed to get it to start charging. (this time at work so had no power point charger)
EDIT: Australian Optus branded phone with no firmware change (still stock, no root, nothing).

Sorry to hear this mate. I also noticed the battery going down faster than it was charging, while playing Retro defense. And the device was getting really hot. If this can damage the phone then I'll stop playing that much with it.
Maybe you have a faulty one?

Here is my finding regarding heat
While running some tests for the robo defense dev to provide a log file so that he can get the freezing issue addressed, i did notice that my phone was getting extremely hot.
I've played plants vs zombie, grave defense hd, etc on charger and i've never gotten close to the heat felt through the phone today once robo defense frozed and i didn't close the app for a good while to create a log dump using adb
Could it be possible that some of these rogue apps are driving the device to 100% usage causing it to heat up?

how hot is extremely hot? The hottest I caught mine at was 48°c. That was while playing a game and charging at the same time

I think that is EXACTLY what's going on... I truly believe some of these games are either not written or optimized for this phone's dual core processor. I can play most games with no problems, including some of the bigger Gameloft games. But, there are a select few games that get the device way too hot for my liking... like Sky Force Reloaded. I have never played it completely through because I can feel just how hot the phone gets even through the case.
I think these issues will be ironed out in time, but definitely app dependent right now.

Definitely true for me. I can play many games for an extended period of time. Plants Vs Zombies, Death Worm, even something graphics intensive like Modern Combat 2 is no problem. But, if I play 10 minutes of Bonzai Blast it's radiating heat and the battery has lost 10%.

Sorry to read this mate.
On a side note, they say 2.3.4 will utilise Galaxy 2's hardware better, it will be more battery efficient and not overheating as much... So until then it may be a good idea not to "abuse" it too much (I know it sound crazy, but hell...)

Quick update:
I've returned the phone to the O2 store today for repair.
This was in its debranded state with the stock KE7 firmware installed, and I think 5 custom kernel install counts.
I think I could have got it back to stock by borrowing a friends charged battery, reinstalling stock rom, and then usb jigging it back to 0 custom kernel installs, but I thought I might as well 'take one for the team' and use this experience to test how flexible Samsung's repair shop is when dealing with handsets like this (HTC repaired my unlocked Nexus one without any fuss)
I've been *very* impressed with Samsung's dev friendly attitude so far, they're not only setting the standards in Android hardware used, but also with how their company recognises the wants of its consumers. I'm sure I won't be disappointed..
Should know in about 7 days!

Let us know if O2 repair or Samsung .
Its often down to the tech that picks the phone up some may just flash the stock rom and not bother others as been posted might be more picky .
As per the O2 store that refused warranty on my SGS1 .
Unlocking will not void any warranty as O2 offer the service themselves as do all networks .

Quick update, still under repair.
It came back once with a letter saying that they (o2) replaced the circuit board, but it was still broken.
It then got sent off again, and I've been told today that its come back from repair with a letter that only says 'BER', which means Beyond Economic Repair apparently.. so they're (the o2 shop) are sending it back for a repair team leader to look at now :-/
Bit fed up :-/

BER is actually good news. You'll probably get a new phone. I doubt at this point the team leader's going to say anything about your mods. He'll probably just rubber stamp it.

I always thought people shouldn't use their phones while charging at the same time
Anyway, hope they'll give you a new one. I always cringe every time I feel the back of the phone warming up...

Not possible for developers When developing an app, the handset will be 'always on', charging, and being used for 8hrs+ all at the same time!
Addictive Japanese quasi-RPG games are a separate matter though..

Pocket legends is a killer. On it for five min n phone got really really hot. Checked temp n it was 44 degrees... Not good

i'm getting worried after reading here. last time i used with google navigation and charging same time, battery heat went over 50°c and it was really hot..
and that was just for one hour google navigation.

Red Light Of Death - Should I Be Concerned?

Hey Guys.
I'm very excited to get my nexus 4 but I've been hearing a lot of people talking about the RLOD!!
What causes this problem and is there anyway to fix this??

the red light is just caused by using your phone the wrong way. it won't happen if you do not flash a custom rom anyway.
And if you flash custom roms it won't happen either, if you follow the standard steps you have to follow on every android phone. It's just a brick that can happen on every android device if you flash broken .zip's or anything else comparable .
People who claim this happened from a moment to the next without them doing anything wrong, are just not telling the truth. Even IF this would happen this way(not your own fault), you could easily get a replacement from google without any costs or problems.

Thanks for the reply,
Ive heard many people who had a completely stock and unrooted nexus 4 say they got a red light of death too... The problem is, I don't live in any of the countries that have playstore devices. So I'm having somebody from the US bring it for me...

propably you could check the rev of those n4's (asking them in pm's). i can't imagine rev11+ have this problem anymore. I still won't believe this happened without a reason

These many people you speak of? That's not even half possible for it to RLOD on pure stock without any mods it's just to save the hardware its the phones built in safety net...unless you plan on OCing to 1.98ghz and set it to performance and run antutu that will most likely do it for you

Hi,
It happened wih or without running an Antutu bench. Yes some users have reported the red light on stock with rev 10 or with rev 11.
Antutu is not directly the culprit, it's due to a bad read of battery stuff (in a stress condition even at 50% battery the phone think you are out of battery then shutdown + heat, there is an issue with some phone about the battery contact inside the phone). If it's happen you can try to let your phone in charging for hours, sometimes it's enough. But the better thing is to open your phone then disconnect / reconnect the battery.
It happened also while flashing something in recovery mod, 40% battery, flash then reboot and bam red light...
Also on a French forum it happened during a download while browsing...
I agree we not know all the conditions together when it happened but it seems this is slightly random. Maybe a combination of circumstances...
It's "just" related to some weird battery reading issue.
For example I ran a bunch of Antutu bench with / without overclocking at different battery % (even at 11% battery ) without any issues, at least until today...
Take a look here: http://forum.xda-developers.com/showthread.php?p=36304348

So does this problem happen to everybody or is only a minority of nexus 4 users affected? Do you think google would've fixed this problem by now??

Re,
It seems it's a minority phones who are concerned...
I don't know if Lg / Google have worked on the problem. As I read maybe the rev 11 are less concerned? But I'm not sure...
Don't be afraid, use your phone and if that happens rma or open your phone, there is always a solution

Alright, read a lot of threads and it looks like removing the battery and starting it again works perfectly. I also read somewhere that its due to too much pressure being applied on the thing the connects the battery to the phone.. - http://forum.xda-developers.com/showthread.php?t=2128392&highlight=red+light+of+death&page=2

Yes, it's what I said, ah I forgot this link.
When you search, you find

Happened to me a few days after I got it (100%stock, not rooted); I left it charging for some time and it turned on again like nothing happened. Didn't happened since.

Only time I had it was when I first rooted.
It got stuck in a boot loop on the "X" screen and when I rebooted to clear the cache the red light flashed and I had to hold the power button in to turn it off.
Booted into recover fine after that.
No issues since.

Alright that's good to hear. When did you guys get your nexus?? Maybe google resolved this issue.

I got mine very recently ordered in late February. It did red light because I flashed a mod which was for the nexus 7 but i flashed it on my nexus 4. I just went into recovery and flashed stock, phone was fine.

Alright. Sounds good.

Got mine last week but it's a Rev 10 not an 11.

That is not true.. Red light appears due to some small chip next to the battery which is hardly put in there, you just need to release some pressure and it will be fine.. (there's a youtube video)

Loosen the screws?? Do you have a link to the YT video?

Ordered mine when they were first available, got it 2-3 weeks later (end of November).

Got a bricked rev11 301k here. Tried everything untill I get my replacement (takes a bit longer since I live in holland). Check out http://forum.xda-developers.com/showthread.php?t=2177787&highlight=nexus+4+bricked for more info. Now I try to drain the battery and let it charge (put it in a cold enviroment for a full 24 hrs. Got past the google logo for half a second and saw the stock recovery before it went dead again
