Runaway CPU process and/or battery overheating for an unknown reason?

A few things:
- running kavanna's WM6.1 080408 ROM
- the phone is pretty much idle (I'm not actively using it when this happens)
- I am *not* overclocked (stock cpu clock)
- the phone/battery is probably 2-3 months old
- no strange processes other than the stock ones that come with the ROM that run on startup
- I carry my phone in my pocket, so it typically happens when I am carrying it like that.
Every once and a while, my phone suddenly gets very warm (on the battery side). At that point, it typically becomes un-responsive/freezes and I have to take the battery out to reset it. During this time, while the battery/phone case is hot, I can drop 20-30% battery charge in a manner of minutes.
Since I have to do a hard reset typically, I can't tell what process is stuck (if there is one) and/or what else might be happening behind the scenes. I take the battery out, reset it, power back up and all is fine.
This doesn't happen often, but it happens enough to where I would like to see if anyone else has this strange gremlin pop up every once and a while.

I had this exact same issue beginning of last year. Come to find out, it was the battery

Yeah, I did a search but I couldn't find any definite answer given that my battery/phone were basically brand new.
Hopefully the solution is that simple. What's odd is that when this doesn't happen, my battery holds a good charge for days. Go figure. I wonder if I can convince T-Mobile to send me a new battery...

i had only had my phone for about 2 months when this started happening. Since i did not know what the issue was, i naturally called them to troubleshoot, they ended up sending me a battery as a replacement, no charge.

Yeah, looks like I am going to have to BS a little being that I have a cooked 6.1 ROM on it. I doubt that they will support that given that they only have 6.0 out right now (officially that is, yes?).

You shouldn't have to get them to "send" you one. Just go to your nearest T-Mobile Store and tell them that you've been having trouble with your battery overheating. After enough banter, they should be willing to give you a new one free of charge. I got a new one out of them last year with hardly any effort.

how are they going to know which ROm you are using? just tell them that the phone locks up and when it does, you feel the phone getting very warm, also tell them that you've already done a hard reset and let the phone set after the hard reset without any 3rd party software and it still locks up

Just called and here is the status:
- The battery is only warrantied by T-Mobile for 3 months (I've had the phone for 3.5 months, so they cannot warranty it). However...
- The battery is warrantied by HTC for 1 year, so I have their number.
- T-Mobile is sending me a new phone in case this is a hardware issue (does not come with a new battery, however).
So, I'll try the new phone with the original battery. At least I will get a new phone with no scratches on the screen (can put my screen protector on). If the problem still persists, I'll then contact HTC (have their support #) and have them replace my battery.
So, all should be well 'cept for the fact that I have to reload my ROM again along with all of the settings. Oh well...

make sure that you re-install the original t-mobile ROM on the phone you're sending back. otherwise they may end up billing you later on, for "non warranty" part

Random shut downs?

Hi guys. Haven't been here in a while. My daughter is now saying her cap. glide is randomly shutting itself down- not related to low battery. It happened 3 times in one week. When she powered it up the battery was fine. The phone is about 9 months old. I think it has a 12 month warranty. At least on the samsung site it says 12 months. We got it from ATT with contract renewal.
I read that the regular Captivate had this problem. Did it flow over into the glide? Haven't found anything about it. I assume ATT will replace with a refurb if anything.

I use mine pretty heavy and havent noticed any problem i assume that you are running the phone completely stock and if so i would suggest that you download samsung kies from samsungs site and run it then plug the phone in and it will ask you if you want to update the phone it may run better on the newest firmware that there is other wise i would download avgs free antivirus app and run it to see if there are any apps that might be to blame i would post links but to avoid spam i am not allowed

Thanks for your response. Yes, it is stock rom, but I have it rooted with CWM recovery on it. I don't think kies can update it due to CWM. And it's in another state. LOL. But good to know you don't have the issue. As for running antivirus, my daughter does not even know what that is- she barely runs it on her computer. If I ever get my hands on it I will try your suggestion for AV.

Could be a battery issue... mine did the same, and when I took out the battery it was slightly swollen.

Thanks for that. I'll have her check it out.:fingers-crossed:

Interested in your solution
My wife's Captivate Glide just started having random shutdowns last week. I came over looking for a "return to stock" thread hoping that putting a new OS might help when I saw this thread. I've been reading xda on the GalaxyII boards since getting mine last year so have some familarity with xda. Wife prefers to not update OS so I want to avoid ICS. She had AVG installed and I added Lookout to scan with it also and can't seem to find an issue with those. The problem for her mainly manifest itself when she has the internet turned on. The phone will basically act like the battery is critical and do a shutdown even if it is over 50 percent. power up with the cord in and it still shows good charge. If I find something that works I'll post it here also.

I have random shutdowns/boot cycles too. I've narrowed it to a hardware issue. I was running rooted stock rom, but also ran liquidsmooth and now on aokp rom, and its still happens.
I posted a topic a couple weeks ago, asked if anyone has any experience replacing the power button..its not that it sticks, but if pressed the wrong way in the wrong spot, the phone goes into endless boot mode, with the samsung logo up for about three sec, then black, then samsung logo, then black.
The timing is rarely the same. There's no debris or gunk. Its not battery. Its not overclock issue. Its something to do with the phyical power button.
Can I diasble power button using key remapping?
Sent from my SGH-I927 using xda premium

Having the same problems with my Glide, and I really do think it's a hardware issue since my battery looks fine. After reading many threads here and elsewhere, I'm resigned to the fact that it can't be fixed, but more suggestions are welcome.

My daughter has had this phone for almost a year and it just started happening to hers. She is very hard on her phone. 5000 texts/month with alot of drops. She just might have abused it to near death. lol.

Random Boot
Hello guys;
I think I'm having same or very similar issue.
My phone is randomly shutting down; some times is in cyclic restarts.
Did you guys came up with a solution to this problem?
Thanks

5000 texts per month?
Does your daughter know how to speak or is she only familiar with written language?

If you're on a stock rom, it's almost certainly a bad battery.
Battery voltage will drop when it's hot or if it's damaged. When you turn it back on, the phone says you still have plenty of power left.
What the phone is really doing is making a guess about how much battery life it has left.
It knows the voltage. Now, if you know the voltage a battery is producing with no load, you can get sort of an idea of how much more life you can get out of it. The phone keeps track of this (roughly) and tries to guess. It's also not going to let the battery drop too far down below 3.6 volts, it will shut it off for safety, because if you truly completely discharge a lithium battery, you can't charge it. (there are tricks to get them going again, but it's bad for them.)
And a damaged battery can have plenty of volts, but once you put it under load it will drop sharply. The phone will power down to protect the battery, or it just won't be able to stay on any longer.
Anyway, pull your battery. Make sure it isn't bulging. Pick up a spare off of ebay for $10 and see if it is better.
Or if it's under warranty, just take it in.

Lol.... Sometimes it's only 3 thousand. But you are right. The art of communication is being lost on this generation of kids who rely on computers, tablets, and smartphones. Instead of calling, they text about everything.
My daughter is graduating:victory: with a double major- Theatre and speech (performance) so we know she can talk and sing and psychology with ambitions to get a masters in dance therapy to work with autistic kids....

Very informative. Thank you. She did pull the battery and it was fine. It is about a year old. I got her 2 replacements and she just doesn't use them. I will suggest that she switches to a new one- although they are almost a year old too, but unused- I charged them up once before i gave them to her.

phone saga continues!!!
:silly: Well, my daughter being sooooo poor that she couldn't buy herself a BOX of tissues(cough-cough), she was pulling toilet paper from the dorm bathroom and plop! OOps!! Her phone fell into the drink! (toilet bowl!!)
She knew enough to pull the battery and used a blowdryer to start the dry out process, and put it into a bag of rice. Didn't leave it in long enough and tried to power on- did a little dance, and it died. I thought she fried it, but she put it in rice again- battery pulled and slid in the open position.
2 days later she called us on it- (today) and it seems to be working!!!:victory:
So, Rice saved the day again! :silly::good::highfive::fingers-crossed:
We'll see how long it lasts. I bought a cheap go phone last nite on att for $21 as a temporary replacement. Maybe it won't be needed.

Help!!
Hard to believe my glide is begining to give problems. After flashing a stock kernel on spike55 jb 4.2 rom,i started getting random app crashings. So i sought to revert by flashing back the original jb ROM,but it got worse. Now i was uable to get network and my baseband version displayed unknown also i had random reboots.
At this junction, i realised i had to revert to stock. So i got a stock ICS rom from sammobile, flashed it via odin and whala! Problem seemed solved. So i flashed CWMR and reflashed jb 4.2.
Afterward, all seemed well not until the random reboots came back. So here i was thinking about my phone being tired of all the flashing and wanting to be on stock. I went back to stock, but the random reboots still lingers.
Though i have a feeling the problem is with my power rocker cos only a little tap pops up the power menu.
At this junction, i dunno what to do. I'll be very grateful if i can get any real assistance from anyone. Thanks a bunch in anticipation.

So I thought I'd post again. Daughter home for good. Started complaining about her battery again. I found her 2 spare batteries that were never used. Had her make the switch.
Then I looked at the removed battery. It was slightly swollen. You had to look straight down to tell. Looking at it flat, it seemed to be fine. But put it on end and it had a slight bulge. So it was a battery going bad. We caught it before the phone was damaged.

Hello!!! Back again My daughter ran on macadam and her unprotected cap. glide plopped out of her sweatshirt pocket and hit hard. A small hairline crack in the screen, but it pretty much killed the digital panel. She had it for 18 months and for her, that's a record. But she loved the phone.
We just got a new one unlocked one off amazon for $138. No contract renewal for her.
If anyone is still reading this thread, her OS is 2.3.5 or 6. Is it worth updating to ics? We don't have kies installed so it will be a job to get everything installed, get drivers working, etc. She will be happy with GB. Last time I made the change to swap external and internal sd cards and she had no problems.
So is ICS worth the effort? Battery life? Can the sd swap trick work? Any advice will be appreciated. Presently it is new and stock.

..it might even have come with ICS, the UI differences to GB are very slim.. Can't say more because stock roms are far inferior to the beast called P.A.C.man ROM :laugh: :good:
Really depends if she is tech savy and will explore the depths of customizability and usage... If so, http://pacman.basketbuild.com/index.php?dir=main/i927/nightly/ is the next place to go
Nightly builds 'been broken for 10 days now but should be fixed soon by awesome @kick buttowski :good:
And on a rooted phone, Titanium Backup can import/export SMSs and contacts supposedly even over to a different rom. (Still struggling a bit getting all my contacts ported from the sony xperia system, but..)
Oh by the way, one of them plastic hard cases is about 5$ on the bay
...It's not water proof though

Nice to see people are still using this phone. As far as the case- I must have bought 5 of them for her. She didn't want them on her phone. Now that she paid for her own replacement, she may rethink that one! lol. She is not tech saavy at all, so custom builds are not her thing. I didn't even do the mods on this phone that I did on her original. Thanks for your input. OH, it's still GB.

[Q] Huge Battery Drain but no wakelocks

How is that even possible?
I have attached 2 screnshoot of a Galaxy Nexus battery drain.
My phone is 100% stock, I just restored the nexus official image. The battery should be new, I already sent the phone to the manufacter last month and I think they changed the battery.
I didn't even setup a google account, no app installed, wifi off and there is good signal.
There are no wakelocks. Screen was off all the time. The battery just go down.
(Some translation. Segnale rete mobile = mobile network signal, Attivo = active, Schermo Acceso = Screen on)
What should I do? Call samsung again and stay another month without my phone? Is there any other solution?

Well, for starters you could let it charge for another cycle or two to be sure about.Also I see the Network reception is not so good.That may be responsible for the drain, though I highly doubt it !

I have the *exact* problem (or at least, similar).
I have RMA'ed my phone 2 times, teling me they had done a "mechanical repair" (in Italian, as per repair center label, "riparazione meccanica").
Don't ask me about the meaning of this. It could be everything, but one thing is certain: serial number of the phone is the same, so they did not change the motherboard at all.
Back to topic, I'm experiencing serious issues:
1) huge battery drain in airplane mode, even after complete stock and several ROMs (the service center restored 4.0.4 on it, funny)
How did I test: the day I received back my phone, I have simply fully charged it, switched to airplane mode overnight and I have lost more than 30% battery with NOTHING at all installed, I even left the wrong date/time !!
2) before RMA'ing it, it did not matter if I used 3G / WiFi or nothing at all: I always got a similar battery discharge curve.
BUT today I noticed something odd:
while testing for the (1) issue above, I noticed that the "Awake" (aka "Attivo") bar under the battery graph was pretty full blue colored, which is NOT normal actually. How can it be after a full wipe (or so, as per after sale service) ????
Let's try to troubleshoot this problem guys, because I'm really fed up
...and I don't want to sell this Nexus, I simply love it hehe
TODO:
1) Wipe and test again -> charging the phone right now
2) analyze dmseg (maybe there is an hardware issue that keeps interrupting the CPU) -> after a quick look it seems that actually my interrupt idea could be true ( "Resume caused by IRQ 39, TWL6030-PIH". This is the power management unit) but I have to see during the airplane mode test, not while charging (that might be correct)
3) measure the current and compare results against a nice study of another guy (that reported power consumption on different scenarios)
4) ??

The same. They changed the battery in my case. I did a mark with a marker pen on the battery before sending it and the mark is not there after RMA, so they changed it. Phone serial is the same.
They also put 4.04 on my nexus, what a shame!
I did not experienced the "active" thing on the battery statistics. I had several wakelock from "RILJ" but after a full restore the disappeared.
I restored (again) the phone with nexus image, and even locked the bootloader, removed the sim card and disabled wifi, gps and everything. It always discharge by itself in a too short period of time.
Is there something I can tell to RMA to make them change my phone? I don't think it's a software problem.

I agree, this must be an hardware problem.
To say, I have tried a long list of ROMs and kernels, as well as updating radio and all other sort of stuff.
Now the awake "problem" has gone, so today I'm gonna retry the (1)st experiment.
Let's see...
In any case tomorrow I'm going to go to the shop and ask them if they could be so gentle lending me a fresh battery to test out.

No, I never used tethering.
My phone is at RMA again, I asked to fix it FOR REAL, I'm just hoping.

I've had a similar experience since first getting the phone. While with light usage, I used to get anywhere between 16 hours to a full day of battery life, I'll only get between 4 and 6 hours of screen-on time. Whether full stock or ROMs, it's always been the same. I've eventually just chalked it up to hardware being the issue and made sure to always have a spare battery and charger with me at all times.

I got my phone back.
They said that they changed the motherboard. On the package the note is "sostituzione board unit".
In the next few days I am gonna do some test to see if they really solved the problem, I really hope so.

Nice to hear
Today I was suprised of my phone's duration (still no serviced again): more than 1 day (of course without doing much) and only 10% drain during the night.
I don't know what happened BUT i can say also that I'm experiencing now a problem with the network (GSM, 3G): the network crashes sometime also while calling or while idling.
Today it did not crash in a > 10min call, so let's see also the battery drain during this night
...because strange stuff happens!

try update to the latest new radio.. flash radio.img
galaxy nexus i9250

I think that the problem is solved.
It was a hardware problem.
I'm on CM10.2stable now.
Latest radio and bootloader.
Now my phone last enough .
I called Samsung a lot of times to urge them to fix my phone.
EDIT: I'm now on 20h20m on battery with 3h23m screen on and 4% left. Goood

[Q] LG G3 Turning Off Problem

I have randomly started experiencing a problem where my device would turn off randomly which has gradually gotten worse to the point where it's stuck in a boot loop sort thing and will shut off randomly during boot then restart.
The problem started by every now and then (sometimes not happening for a day at a time) the phone would turn off then turn back on again gradually getting worse. The problem started when I installed the latest update during the update the screen froze (no it was not interrupted in anyway and done officially through the phone) so after leaving it overnight and it not progressing I took the chance and removed the battery. it then turned on and finished the update without an issue. The phone has since as I explained got into a 'boot loop' sort scenario where it will work if the charger is plugged in but couldn't be a battery issue as doesn't turn off if I put it into download mode. Things I've tried: Doing a complete reset- Still no fix. and now today I entered download mode and re-installed the firmware which was successful but still no prevail?! What the hell could this be?! Thanks

The phone has since as I explained got into a 'boot loop' sort scenario where it will work if the charger is plugged in but couldn't be a battery issue as doesn't turn off if I put it into download mode. Things I've tried: Doing a complete reset- Still no fix. and now today I entered download mode and re-installed the firmware which was successful but still no prevail?! What the hell could this be?! Thanks

Maybe it's a hardware issue

hi, where did you get the firmware? it could be corrupted. if I were you I would download again the firmware and reflash it.
after that I'll do a hard reset.

I have randomly started experiencing a problem where my device would turn off randomly which has gradually gotten worse to the point where it's stuck in a boot loop sort thing and will shut off randomly during boot then restart.

Well i guess im not alone as i have the same exact problem as you do! WHich version do you have? I have the White T-Mobile version and i bought it the same week it was on sale i felt that i got a phone that was part of a bad batch because of some problems ive had with it but i didnt buy insurance for it. i was on LG's OS and it started to get worse and worse so i restored it and went to a lollipop rom. its still happening but it only reboots once. however, as soon as i start using apps it reboots on me. i want to unroot it but at the same time i dont want to go through the trouble of rooting it again. Any ideas of what it could be?
My problem just randomly started happening and i noticed this started happening strangely after my phone completely died on me and didnt want to turn on so i connected it to the charger and it started charging but had a yellow warning triangle somewhere on the screen.

Hey, nice to hear someone has the same issue, I however hvent had the yellow warning triangle come up yet, as an update all of a sudden it keeps turning off as soon as it boots even on charge!!!??? It just keeps getting gradually worse?! However I have noticed the battery % it shows when turned off is 100% and very randomly it displays 70% then when the phone boots it will show 2% for the 2 seconds it stays on before it dies?!

Wait now it reboots on you even if its charging? I too started noticing that with my battery . if I turn it off and charge it it and lets say it says its at 75% well I turn it on and its like at 40%? I really don't want to buy another battery but I actually hope the battery is the culprit. There's a guy with a G3 in my school I'm going to see if he let's me try his battery out on my phone I'll keep you posted

Hey sorry for taking so damn long on replying i've been busy studying for some exams.
I've got good news for you though, i took my phone in to T-Mobile and showed them my problem. Without me putting much effort into persuading them, they shipped me a new phone, and no i didn't pay for insurance on T-Mobile, this was covered by LG's 1 year Manufacturers warranty!
Anyways, I received the device but did not receive a battery. So i tried my battery on the new one and what do you know? SAME PROBLEM!
So yea you should either try to unroot the phone and take it to the store but don't mention that you think its the battery, they'll send you a new phone! Then just buy a battery online or call them after a few days and say your problem is still occurring with the new phone and see if they send you a replacement battery, im a little skeptical on this second option as id rather keep this new phone haha

Hi, even i am having this problem, my phone is a D855 and in my country (Mozambique) i am not using a contract so its different than US, we have a LG store here but in the LG website our country is not stated. So only way is to go to a trusted Store that repairs phone here. My question is that, when its not connected in the charger it just keeps reboting (the notification LED doesnt even blink) infinite times. At first i thought it was a software but after going from Stock to Cloudy to CandyRom the problem was still there. Then after i plugged in a charger the phone would succesfully boot up and i could use it normally but had to stay connected on a charger. So what have you done to fix this? Did you replace the battery with a new one and then it stopped rebooting?? Please help me as i want to buy a new battery but first want to confirm if its the battery at fault....

Hello buddy, sorry for taking so long to reply. Im usually not on XDA too much. Yes i solved my issue with a new battery. I tried my bad battery on 2 lg g3s and it rebooted both. I also unrooted my phone and flashed a completely stock update and was still having that issue.
I hope my response isnt too late for you!

No problem bro! Got a new battery and do far my phone doesnt reboot, but the only problem i am having is that my phone shutsdown at 30% battery and when trying to turn on it says it has 0%

Im having the same problem gotba new battery and no different so annoying

Best thing just happened. I had the G3 for a while and my first one had an issue and had to get a warranty replacement. Long story short... I got two more G3s from T-Mobile that were defective and most carries have a policy where if you get 3 warranty replacements you can chose a different phone. To wrap it up, you can ask for a phone of equal or lesser value when purchased from the carrier (I bought mine off eBay and they didn't even notice, I spoke to several reps and no one caught on.) So they can either send you a whole new phone, a new battery, or in my case: I received a new LG G4 since I had gone through three which pretty much anyone can do with a bad battery.

Guys. Im having this same exact problem on my LGG3!!!

Expired Battery or Faulty Power Button could be the culprit
This issue just started happening to my LG G3 over the last 2 weeks. I've had my LG G3 for exactly 15 months and all of a sudden it started cycling endlessly and if it did get to my locked screen and i tried to unlock it it would just restart again.
I found that when I plugged in the device to a wall charger or high power power brick, it would halt the reboots but otherwise it would get stuck in an endless cycle of partial reboots (when it did stop after plugging in, I would find all my apps still open and waiting for me, so they weren't real power cycles).
One of my coworkers has a newer LG G3, so we swapped batteries and immediately he had the cycling issue on his phone and with his battery in my phone the issue vanished.
On closer inspection, my battery was a few months past its expiration (FYI to anyone with a LG G3 - your battery will expire more or less exactly as its warranty protection does!), so went and bought a new battery and everything is fine now.
For those of you who have tried replacing the battery and find it still occurs, another coworker said his wife had a similar issue on a different device and it was resolved by having the power button replaced, so it is possible that this could be a factor also and you should have your phone sent in for inspection/repair.
Hope this is helpful for some of you.

I've had the same issue since February, when my phone was about 17 months old. It kept turning off saying SIM card not detected. I tried replacing the SIM card and washing that area with alcohol with no luck. Then I replaced the battery with a second one that came with the phone which I'd never used, but I noticed no difference. It also has no phone service for several hours without my knowledge. LG just told me to reset the phone, but it looks like that doesn't work from what I've read. T-Mobile said they'd give me a new phone but there are no G3s in stock and offered me a Samsung 3, which is three years old, so I am worried that it won't be able to handle the software updates. It's ridiculous that a phone that costs this much won't even last long enough for me to pay it off. My last phone was an Iphone, which I had for more than four years.

I had the exact same problem a few weeks ago, posted a detailed explanation of the problem and got 0 replies and a few hundred views (thanks guys!)
Easy answer:
Replace your battery
Thats what I did, and the problem is now gone. When you do get a new battery make sure you drain it completely first, then charge it for 4 hours without exceptions.
I tried factory resetting, installing a new firmware, going to stock and going to custom but nothing worked.
The girl in the shop where i bought the battery surprised me, i just asked her if they had one available and her immediate reply way "why, is your g3 stuck in a boot loop?", apparently EVERY SINGLE PERSON that bought a g3 battery from them had the exact same issue.
Now the problem is gone, and my phone actually lasts longer than before.

Hey, I am having the EXACT same issue. LG G3 was stuck in an endless loop, replaced the battery, now it works down to about 30% and shuts off. When I try to restart it says 0%. I even tried a third different battery, and still getting that 30% shutdown. Did you ever figure out what it was? I am wondering is it something to do with how the phone reads the battery charge i.e. does it think the battery is dead when it gets to 30%? It has e stumped!! Any advice would be most welcome. Thanks.

wtf,actually same with my LG G3,after when I bought a new battery. Shutsdown at 30% and it says has 0%.

same problem

I HAVE THE SAME PROBLEM help PLEAAAAASE

Faulty battery that wasn't faulty for 8 months?

Okay I recently wrote a thread about the random restrarts on my g3 that happened 10 times a day, but the things have gone too far. As i was having random restarts when I monstly use the camera but not only for about 5 days and some of those restarts were also shutdowns now the problem is more serious. Today i was intending to take a picture of something and as usual the phone restarted but STUCK on the startup boot "picture" that says that lifes good and then goes black screen and startup picture and black screen and so on. I wasn't able to use the phone. I pulled out the battery and tried again but it didn't worked. So as I went home i plugged the phone ot the charger and when i powered it on it started normally and tried to take pictures and there weren't any problems. So I think that this is the battery that is making this **** to happen. I highly doubt that this is software problem but from my quick examination i think that the problem is from the battery . What do You think. Tommorow i will go to my carrier and "ll try to explain them about this. But they are usually jerks who don't know anything about phones. They only know how to get your money.Anyways. Yes.

Are you rooted? Did you flash anything? Did you edit any system files? Looks exactly like when I bricked my phone. There is a fix. Check out this thread and the links in it. http://forum.xda-developers.com/lg-g3/help/lg-g3-unbricking-steps-clarification-t3119844
Also can you access download mode or recovery. You might want to try them first.

No I havent rooted it or made any system modifications. This problem occurs only when my phone isnt charging. When iits charging even at 100% there isnt any problem

I've gone to my stupid carriers office and explained everything but they do not want to give me a new battery unless they bring the phone to the other end of the country for repair. This is extremely stupid. Now I can't use my phone because its totally "bricked". I xan only use it with my original dc charger if i unplug it the phone shuts off. Yesterday Ive decided to make a factory reset, but i wanted to copy my internal storage to my pc, but the phone won't turn on when its plugged to the pc. I don't know what the **** is happening with this 500 piece of pancake.

well i have finally decided to do a factory reset but after the anticipation and thinking it is a software problem it isn't apparently. Maybe i will just send it to repair and hope that i wait less than 20 days for it to come back. And i hope that they don't figure out the problem and send a new phone but i think it is the battery that is the problem. Anyways the modern technologys are the most incredible thing and the most getting you pissed of one. You pay 500 dollars+ and expect something good and there you go .

So did you do factory reset or not?
Btw, getting phone to repair center is a good decision, they'll see what's wrong.
I have been happy with my G3, only "minor" thing I don't like is the horrible backspeaker (coming from HTC One m7)
