My galaxy S freezes out of the blue, and i can't even turn it off. Sometimes i look to check the time, and noticed the phone is turned off. Both problems are only corrected by taking out the battery, and putting it back in...and then waiting for it to happen again!
Is this a software issue that 2.2 will fix? Should I exchange for a new one, or will all of them have the same problems, if bought from the same place? (Best Buy in Vancouver Canada)
either your battery is not good, or your got a defective phone
the new SGS out of the box works smooth
what is your firmware version?
type in
*#*#1234#*#*
Sounds like a bad phone. I got mine from one touch in delta and it has been perfect. Return asap and get yourself a working unit.

Thought you meant lag. Mine lags a lot (stock firmware) and sometimes "freezing" seems the word.
But no, that's not it. Perhaps you can try a hard reset and check your sdcard too, something isn't ok.
I'm actually experiencing the same issue. My phone goes black and seems to be happening more in low wireless connection areas. Like in a mall. With the the *# code I get I9000UGJG9.
if you have LAG issues, install the one click lag fix in the development area
problem solved
Its not LAG issues it a complete freeze issue. My phone goes black like standby mode and will not come out of it. The only fix is a battery pull or holding the power button for 6 seconds. The same issue as the op.

that is a factory defect
take it back, exchange it for a good one
this latest firmware is really good, you should not see anything like that
Allright will do. I figured as much I didn't want to bring it back I already purchased some apps. Guess I'll have to wait for my store to get some.

you do not lose the Apps
once you log back into your Gmail account in your new phone, when you go into Android Market, they will remain in the Download section
those apps are saved in your Gmail account, not in the phone.
that's the cool thing about the android phones
so if you ever switch to say an HTC Android, or a Nokia Android, you can still re-install those apps (assuming they are compatible)
Oh sweet I wasn't aware of that. I sold a couple of the Galaxy S and I'm the only one with this issue as of yet. Hopefully it isn't a common one. I've been trying my best to convert Iphone buyers in most cases when I'm sold out to get this phone I just hope it delievers for my customers and they won't have the same issue as me.
Are u futzing with oclocking or changing CPU mode ? This causes hangs with black screen

I believe this same thing just happened to me. Plug in my phone to recharge it (got it 2 days ago, so the battery still runs out quick) then tried to activate it and Lock screen wouldn't disappear when sliding.

you do know you don't just slide
you have to move the entire picture of the "slide" out of the phone frame for it to unlock
if you say only slide it partially, it will just bounce back and remain locked.
if you have thick fingers it wont work properly
you might be better off using the 3rd party unlock screens, specially the kinds that needs no sliding.
i have that issues nowadays too. randomly "freezes" on the black screen, i can call through my phone (ringing) but there's no notification / vibration or anything or sorts.
the only way is to reboot the phone and it'll randomly happen again after some time >.> and the call that i've just missed isn't showing on the call-log either.
i hope it gets better overtime or i'll just have to reflash!
ps. was fine before i tweaked my cpu settings in sleep mode, you might wanna disable that if you're using it.
Mine has the same problem and by the looks of things a lot of people have this issue. I called customer support and after sometime the rep admitted this and said it will be fixed in next build however I doubt that
Then there are probably lots of diff units out there. The phone shouldn't freeze unless you are using a beta/alpha firmware (pretty unlikely - i've tested more than 10 different firmwares without a freeze), or set the core clock of the cpu to a higher & unstable frequency (OC). people claim that their phone can do 1.2ghz - that's nice, but each chip has a different capability.
This is not a troll posting. I swear...
I've had the AT&T flavored Nexus One since the day it was announced and I just can't suffer with it anymore. I'm running stock FRF91 with an unlocked bootloader. The only reason I unlocked the bootloader was so I could root and uninstall the apps that drained my battery or sucked resources that I never used - Twitter, Amazon-MP3, Genie-Widget, etc.
Pre-Froyo, it seemed pretty stable but the OS was very immature. Some things were just not well thought out. Activesync for example.
Post-Froyo: Turn on GPS, reboot. Talk on the phone for a long period of time, reboot. Charge the phone, reboot. Use Bluetooth, reboot. GPS is 100% useless now as after just a few minutes of use, the phone gets hot and reboots the phone. Hell, leave the phone in the sun in your car and it gets hot and reboots. Froyo offers some new features but some areas of the OS are still neglected and way behind where they should be. Can't move emails to a folder? Seriously? Can't undelete an email you accidentally deleted? That's just stupid. And there are a few other things that Windows Mobile had right for the last 10 years.
Yesterday alone, my phone rebooted several dozen times because I was trying to find a location with GPS and I was completely turned around with no idea where I was. I finally had to power off the phone, leave it off, and go ask someone at a gas station for directions. The phone reboots as soon as it gets hot and it appears everything makes the phone get hot.
Rip on Windows Mobile all you want, but I never once had a Windows Mobile device reboot on me and not do what it normally does. I'll throw CM6 on my N1 when it becomes final to see if things get better and I'll thrown on Gingerbread when that finally drops, but unless one of those solves the constant reboot issue, I'm done with Android. I've kept up with the Google forums and many, many, many people have the same issues I have so my N1 is obviously not an isolated case.
There are a lot of things I do like about Android so I'm not bashing Android. I like Android enough that if my phone didn't reboot constantly it'd be my primary platform moving forward.

I've had my N1 since the day after they were released and it has never rebooted spontaneously. Your phone is a lemon.
Try calling HTC?

I agree, the only time my phone gets hot is when I leave it in my landscaping truck while I'm mowing, but I think any phone would have problems when it's 112 degrees outside and probably 140 in the truck.
Sounds like a bad phone. The only time my N1 rebooted was when I had an experimental rom on it.
Sounds like something is just borked, I use my phone all day it only reboots because I want to go into recovery.
Are yur using custom recovery? Wipe the cache and dalvik-cache.
Same as the above poster, mine never rebooted spontaneously even when hitting over 40C degrees. Only does so when I'm running some cutting-edge alpha kernels/ROMs, and then very rarely.
I was thinking it was specific to my device as well. I then googled "Nexus One overheating" and was overwhelmed by the number of people with the same issue. I also own over a dozen HTC devices, I've had ZERO problems with any of them. I've wiped my cache quite a few times. I've even wiped the phone and started fresh.
I've googled every specific issue I have had and found many others complaining about the same thing. Overheating/locking up the device when charging overnight - check. Rebooting/overheating when using GPS - check.
Lately, I've been uninstalling anything that runs in the background that isn't an essential part of the OS. Makes no difference. When I first got my N1, I used the GPS and Car Home app to drive an 8 hour trip. Not a single problem. The very first time I tried to use Car Home after going to Froyo it rebooted after just a few minutes and it's been that way since. I found MANY posts that confirmed this on Google's forums.
Personally, I think my device is fine. I suppose it's always possible that an app is causing the reboots. For example, the Weather Channel app is always running and that's not the most beautifully coded app I've ever seen...

Device Summary
Device: HTC Nexus One
Android Version: 2.2
Build: FRF91
List Generated By: MyAppsList (market://search?q=com.boots.MyAppsList)
By the sound of it, it's not an app. The phone should be able to take a good amount of heat and not reboot - the only time I got it to reboot was under direct sunlight in a car, it was probably hitting 50 degrees Celsius. If yours reboots every time you do anything - it's time to nandroid, take out the battery and clean the battery contacts really well (on the battery and the phone, using alcohol), flash a bone stock FRF91 or something really close to it, try to repeat the things that made it reboot (shouldn't be very difficult), and if the reboots continue - then I'm sorry, but you have a lemon. And if they don't - change to your favorite ROM and start incrementally installing stuff in small packs, until your testing shows reboots again. Defining anything other than Google account (like Exchange account) is also considered "installing something".
E-Mail quirks are taken care of by E-Mail clients. Exchange server push might be draining the hell out of your battery and heating your phone, check the relevant thread. I really hope you find the problem in SW, but it doesn't look very much like it.
P.S. There are so many ways to get a WinMo phone stuck (my wife has one, I regularly practice using the reset button when doing something with the system) it's not even funny.
thanks for the tips. I'll give them a shot. I read in a couple different threads that HTC has been sending replacement batteries to those with overheating issues. I have a hard time believing it's the battery but what do I know?
One thing I forgot to add about WinMo, I soft reset my device every morning on the way to work. Just a habit I got into with Windows.

Yeah sounds like you got a faulty device. If the above suggestions don't work, call HTC and they should do a swap for you
went to the Google "Device Troubleshooter" support page: http://google.com/support/android/bin/answer.py?hl=en&answer=185837
Step 1: What are you having an issue with?
selected: A hardware problem I'm having with the Nexus One
Step 2: A hardware problem i’m having with the Nexus One
selected: My device overheats
Then it said this:
It is normal for your phone to get warm after an extended period of continual usage, such as a long phone conversation. If your phone becomes so warm that you cannot hold it comfortably, please try removing the battery and waiting until the phone cools off before replacing it.
If your phone overheats to the point of shutting itself off repeatedly, there may be a hardware defect with your phone's battery. Please visit our warranty information page.

So I called support (open 7 days a week - nice) and they are shipping out a new battery tomorrow and if that doesn't work, I'll send it in for repair. Didn't want to replace it because it was engraved.
I really hope this fixes it. I do like Android and I love the community work. iOS blows and Windows Mobile 7 just doesn't have me wanting one.
I'll update this thread when the new battery arrives and if necessary, after the repair work...
I used to have the same problem, but i don't think it was rom specific for me. I had a black case on my phone and my car mount was a black universal one mounted on my windshield. I would use GPS nav and play music at the same time and sometimes make phone calls and it would reboot pretty frequently. Through SetCPU i noticed that the temp was somewhere between 45-50degrees C. only way i was able to use my phone was to remove the battery and stick it in my AC vent along with the phone itself.
So since then i got myself a AC mounted carmount and no longer use my case and its been fine ever since. When ever it gets hot in my car i usually have AC on and the phoen gets cooled by it also. Average temp was around 15-18degrees C while i was using GPS/Music/Calls.
lulz, sounds like your phone had a hardware issue if it was rebooting all the time like that.
I have had my phone on for literally weeks at a time with out a reboot. Android is rock solid stable.
Way to not get your issue fixed and go back to a dead mobile OS that was never developed properly in the first place. Good luck with that champ.
My phone could stab me in the balls all day long and I still wouldn't revert to the current winmo.

Fact: Windows Mobile still does several things much better than Android. And those things are important to me on my primary device.
I get what you're saying though. Despite a few issues, Android is dominating everything in it's wake. But instead of Android spending so much time with new flashy features, they should focus their attention getting the basics right first. Their contact and email handling B L O W S. How about proper email folder handling and a basic undelete function...
I agree with the rest. To be honest, I didn't get my Nexus new, it has had two users before me. It came with Cyanogen Mod, and to be honest I find it gives better battery life and performance compared to the stock OS. If I were you I'd try it out once you get the Nexus back.
I use ROM manager to download and install ROMs, give it a try.
Hey guys Im a EVo user and my girl has an Epic.
Now the next statement is with either running stock or a custom rom
Her phones slows way down and reboot its required, wifi is odd sometimes a reboot to connect, and today her battery became rather hot over 100 F.
Is there anything I can try out on her phone?
Sounds like a specific phone harware issue, i dont get overheats or slow downs, no matter how many apps are running at the same time and even if i charge and use mobile ap all the time, still no overheats here.
Ive Done this on both stock and custom roms and no overheats or slow down..
darn, thankyou for a reply, guess I'll update her ROM and start her off fresh
I don't get slow downs either. I leave my wifi on all day and don't have issues connecting. I only overheated once. Shortly after I got my phone I was downloading stuff left and right, playing graphics heavy games like radio ball, and trying to charge my nearly dead battery all at the same time. When I got the overheat message I figured it was a sign that I needed to turn the phone off and walk away for a little while.
Either the phone has a problem, or your girl does. (which were pretty much your choices to begin with)
Yep no issue at all here usually always on wifi and I'm a heavy user. I get no slow down or anything and I'm on stock rom with bloatware removed.

My phone does slow down after about 2-3 days of uptime. I'm 100% stock, not rooted. Reboot resolves the issues.
After @ 2-3 day uptime the following happens:
1. I've had issues when rotating between home screens where all my widgets & icons disappear, then come back to normal.
2. Also, sometimes my swiping isn't recognized when trying to cycle home screens.
It's difficult to reproduce on demand, thus making my case to Sprint for replacement even more difficult. So I said screw it, just hoping 2.2.1 will resolve the problems whenever its rolled out OTA.

You may be right. I would get a different girlfriend and see if the overheating/rebooting problem continues. If it stops, we know where the problem was. If the problems continue with the new girlfriend, it may be you.
I got nexus 4, and problem is that now and then it shuts down itself... Battery is charging ok, but after working few minutes or hours (no specific time) it just shuts down (idle or working)...
Phone is not rooted, I tried factory reset, and that didn't help either...
Currently it is on 5.0.1, I got it with this version of software so I don't know did this happen earlier on 5.0 or 4.4...
I wanted to do complete root but i'm afraid that it would shutdown itself during the process..
Does anyone knows what can be the problem??
Have you tried flashing the 5.0.1 factory image through fastboot?
Even I am facing the same problem. But for me it does not show shutting down also. It just blanks out at around 40% battery.
Had the exact same problem with my phone until I rooted the phone and changed to a non-stock rom and have not had the problem since.
Hi guys don't know if this helps because mine is slightly different. Mine is reboot itself.
My suspicion is on ram, maybe the device is out ram and then reboot itself, maybe this goes the same to shut down idk (please correct me if I'm wrong). Recently I've put gravity box and I can see how much ram left when I tap the application switcher, it was mind blowing for me. I often find that when you open several application the number of ram available can reach below 500mb (especially chrome tabs, it do have a lot of ram to use) I mean it's a 2 gb ram device wow. Every few days I've checked that when the idle ram is over a gig I do reboot manually. That way my problem of random reboot vanished. Good luck

Screen will not wake from sleep
The device will randomly not wake from a sleep state, and is happening more frequently. I've read that it's possibly linked to a motherboard issue. I have root, TWRP, Xposed. Will flashing a different kernel possibly resolve the issue?
I bought an N4 from eBay and it worked perfectly for months on stock rooted Lollipop. Then it suddenly started to randomly shut down - not reboot, just a sudden buzz and "Power off". I've tried Marshmallow, Chroma, and now Cyanogenmod latest dailies. Plus a new battery (an eBay special, contacts didn't align with screws, but since another suggested fix was to leave the connection screwless that's fine - it seems to hold a charge and works fine).
So my question is - even though the power button seems to be clicky and ok, is it worth trying a new one? I know that it's mainly suggested for random reboots, but maybe it's related?
Or any other bright suggestions? Any help much appreciated.
I bought a new power & volume button and the same "power off" still happens - sometimes immediately on boot, sometimes after a period when it seems to be going ok..
Anyone have any ideas at all which hardware may be responsible? I doubt it's software, since the same happens on all ROMs, rooted or not.
I had the same issue until I reformatted all partitions and installed stock 5.1.1 Now reboots are gone. Looks like my issue was software related. The only change from stock was stability mode from Root Booster
Sent from my Nexus 4 using Tapatalk
Thanks, Hjicons. I wish I were so lucky...
As I said, different ROMS, root/no root, make no difference. It occasionally runs for a day or so, but as soon as I reboot it's back to immediate "power off".
On the plus side, it's *astonishingly* strong. I treat all my phones with kid gloves - always in a completely empty pocket, no keys or coins, in a plastic bag if there's the slightest threat of rain (even my water-resistant Nexus 6), I set them down gently on surfaces, yadda yadda yadda...
So in frustration, hoping to jar whatever component into proper life, I've banged it hard, very hard, on a mousemat, all four corners, no difference. And last night in a fury of annoyance, to stop myself pointlessly wasting time trying to fix the damn thing, I tried to smash the front glass with a heavy torch and the handle of a big screwdriver, hard enough to bring my wife in from another room to find out what the banging was. Not a scratch, not a crack. Gorilla glass is as strong as they claim it is.
But still not working...
Hello,
Forever pretty much I've been experiencing issues with my nexus 6p. I got it second hand but it seemed fine when I got it. Now, however, after a little inactivity, I find that unlock my phone will cause it to crash or reboot instantly. Its right after it unlocks that it does this. It's not every time but it happens a lot. It also sometimes happens a little bit after unlocking the phone after inactivity. Its like when it needs to drain more power from the battery than its used to it will just crash on me.
The only real thing that prevents this is keeping the phone on charge. Then again, it has happened before where it will still die on me. I've replaced pretty much everything on the phone with the exception of the charging board and the main board. So stuff like the screen and battery have been replaced (+more). Not sure what is causing it. I've had this issue before on stock android but at the moment I'm running the final version of Resurrection Remix on Nougat.
How would I go about troubleshooting this?

Good observation. It is true that the reboot happens because of higher performance. It is caused by the four higher performance cores of the CPU starting to work. There is a fix.
What it does is to shutdown those four cores and you will be able to use only four of the lower performance but power efficient cores.
Follow the link :
https://forum.xda-developers.com/nexus-6p/general/guide-fix-nexus-6p-bootloop-death-blod-t3640279
Sorry for my late reply...
Thanks for the solution, but it seems like a very drastic trade-off for a fix. Is there nothing I can try to fix this like a system or boot.img patch that does something other than disable cores?
Either way, thank you.

My 6p just recently encountered the same symptoms as yours. Only way to keep it from rebooting is keeping it plugged in. I've found something that has worked for me so far, maybe it will work for you too. It seems like disabling the Doze feature has fixed this problem for me. I'm not rooted, so I used adb command to do so. Here is a link for the instructions. Hope this helps you too. In the instructions,
it show you how to enable, but can be used to disable with one simple change.
