Random reboots - AT&T Samsung Galaxy S II SGH-I777

My GS2 keeps rebooting, in the middle of texts, browsing etc..at first it was once in a while, now its been doing it at least 2 times every half hour. I also noticed that sometimes before it does this, when I press the power button to turn the screen off it won't turn off, it pulls up the menu with Power off, download, reboot etc..just from a quick press. I don't know what the hell is going on, I love this phone but I am about to put it through the wall!
Anyone else having this issue?
Oh and I am running UnNamed 2.2.1 with tysj's ICS theme v 2.2

Pull a last_kmsg after a reboot.
Although, based on your other issues with the power button I'm wondering if you might be having a hardware failure of the power button... Return your device to stock, if it still acts up, take it in for a warranty exchange.

I woke up, took it off the charger and its stopped -_- Idk wtf is going on with it, where is the last kmsg?

its doing it again..

My first sgsII did that too, even on the box stock rom & kernel. The at&t service center (for whatever thats worth) claimed it was a bad processor and swapped the phone out for a new one.

If you have not updated the kernel on Unnamed 2.x, there's a good chance you have a hardware problem. Return to stock, if it persists, have the phone exchanged as the hardware is defective.
If you updated the kernel to the 2/7 DD release, that has known stability issues, update to 2/15 or 2/16.

Have you tried a reboot? Usually fixes most errors.
Trololololol

thanks for the help..I went and exchanged it. Ugh I hate dealing with those people.

[Q] Vibrant Black out.

Hey, I recently got this phone, and I must say its impressive. It runs so well and a great phone all-around. However lately when I go into department stores or even large buildings, the phone has no signal.
However when this occurs and the phone goes on standby, I noticed that you can't turn it back on without popping the battery in and out.
Is anybody else having this issue? I've been googling it and I can't find anything. Is this an android OS issue? A Hardware issue? or its just my phone doing it.
TLDR: No Signal kills phone? Is this common?
No issues here. If I lose signal it comes back on after im in range. Have you tried a factory reset since you had the phone. I did a factory reset when I got my phone and a lot of the issues were fixed.
This sounds like a weird problem. If its not related to an app or something and factory reset doesn't work, I think you should exchange it.

Actually I would think its a software issue not a phone defect. I have been experiencing the same issue. I'm on my 2nd one and the only way I can prevent it from blacking out like you say is to set it in flight mode. Kinda sucks when you're a cellphone salesman and you pull out your phone to try to sell one then the screen is just black and frozen.
I'd bet money it's all related to the GPS problem. With GPS enabled, and you go somewhere where it cannot get a signal (a weak as it is doing that anyway), GPS enabled apps, especially google maps but others as well, have locked my phone up.
My fix until the fix comes out is to leave GPS turned off except when I specifically want to use it.
I don't its a GPS issue the phone freezes even when the GPS is shut off. I'm willing to bet that the OP is having the same issue and his GPS is off as well.
@ op are you using setcpu app?

Yes it is common fault throughout the Samsung Galaxy line of phones. Apparently pressing and holding the power button for ten seconds will force the phone to reboot, though I can't confirm this myself as it has never worked for me...
Some people have reported that a new SIM helps, others recommend the NoBars app. Personally I've tried both and neither have helped, leading me to think that this is a yet another hardware/software bug that can only be properly fixed by Samsung. It's perhaps also worth noting that I've had this happen to me 12+ times on two GT-I9000s running stock firmware with zero modifications.
I've entered a building where I work and have lost signal many times and ate lunch for nearly an hour. I just get the no signal image, but never blacked out.
It is true that holding the power/lock button for aprox 10 seconds will force a reboot.

ive had the phone freeze a few times due to the gps **** and holding the power button has always rebooted the phone. you might have to hold it longer than 10 seconds depending on how hard the phone has locked up, but it eventually reboots.
Okay reformatting worked and fixed the signal issue. Musta went app happy and installed something that messed it up. Now that I reformatted i was a little more cafeful with what i Installed. However lately now my back and home keys has glitched and every time i push it, it either holds the menu key and goes to search or disables them for like 10 seconds
You must have install something the first time that is making your phone act up. Recommendation master reset your phone is like it come out of the box. That's what is master reset in case u don't know. If that's doesn't work get a new one. I am pretty sure they will change it cuz they did it for me.
Where do I master reset? I did Factory Data reset in the privacy settings. Is that it?
Okay doing a master reset. For those who need to know the combo. I did
Volume up + menu + power
So far this is a fix. Lets see how long it lasts.
Update: Going to take it back tomorrow. This must be a hardware failure.
That's not a master. You do it from the priv section with phone on. You will also have to call samsung if older then 15 days.

I've locked the phone on 3G many of times, and when I go home I lose all 3G so the phone is in emergency mode.. sounds like you need to flash the new firmware.

Phantom button presses! Is my phone broke?

Is my fascinate defective? Why does my back button randomly press itself? In fact, it seems like it's doing it as a long press sometimes since pressing the power button takes a random screen shot!
I've posted about this before, but this issue came from EB01. Surely others are experiencing such a thing!
This happened to me on stock DI01. I don't know why, but all of a sudden one day, it started doing those phantom presses. For me it was the back button and menu button. I also had a hard time long-pressing the home button to pull up the recent app list.
I have insurance through Verizon, so I just took it into the store, and they ordered a refurbished replacement for me. I didn't have to turn in my phone until the new one came.
It's a different story if you go directly to Samsung. Through them, you are without your phone for 6 days (2 days shipping there, 2 days repair, and 2 days shipping back), and no temporary phone is provided. I was only going to do that as a last resort, but Verizon actually came through.
The end result is that the new phone is definitely better, and I can tell there's a difference in the button response - not in a bad way, though. It's a more "solid" experience as opposed to the previous phone being more finicky.
I have this same issue as well, and have had it pop up on me well before EB01. It's not all the time, but it happens often enough that it's annoying as hell.
Anyone happen to know of a software based solution? Considering all of the rooting/etc. I've done to my phone, I don't know how feasible it is to get replacement hardware..

I believe that if you were to odin back to stock (or any official OTA update) that they wouldn't know you'd ever been rooted.
Superclean 2.4 Voodoo - VA Green
I have the same issue. In fact, it just happened a few minutes ago. Sometimes it only had one phantom press, other times it will go spastic. When the latter happens I have to press the back button to make it stop.
I'm glad I'm not the only with this issue. Looks like I'm calling for a replacement tomorrow.

That's what I did. I was rooted and removed a bunch of the VZW bloat when I first started seeing it. I ended up flashing an Odin package for stock/unrooted DI01 onto the phone to make sure that rooting didn't cause the problem. It still ended up happening on stock. I took it in to Verizon and had them look at it, and they were none the wiser. It's been a couple of months now, and I've heard nothing about my returned phone.
Both the DI01 and DL09 Odin packages should be available in the development forum. Be sure to disable voodoo (if you are using it) before you use Odin.

Doesnt verizon insurance go through asurion or something like that
Blue Super Froyo
Verizon should be quite familiar with this problem at this point. This problem ran wild on the OG Moto Droid. I've had family members return their phones and within the first year get replacements per warranty (factory defect).
The problem stems from either using a charger that doesn't have a USB module (aka doesn't require you to plug the USB data cable into a charger brick) or from improperly plugging in your phone (for instance, not putting the phone in a dock completely or having the USB connection slip partially). The unusual changes in voltage kill these smartphones and cause them to almost short-circuit, resulting in the "ghost" phenomenon. Many people have had this problem within the last couple of years and have found this to be the culprit. Just google "Ghost Droid" for more information.

Verizon's insurance does go through Asurion. That's not what I did, however. I told Verizon I didn't want to make an Asurion claim (which comes with a $89 deductible). They said I could go through them for the Samsung warranty. They sent me the replacement and then I sent back my phone (like you do when you make an Asurion claim), but there was do deductible or charge for it.
Now, they might have only said this because I have the extra protection through them. I can't guarantee they will do this for everybody.

Your phone comes with a 1 year warranty from Samsung for hardware issues. Assurion picks up if the user damages the phone, like dropping it or water damage.
Update for anyone following this thread..
I got a replacement phone and restored via nandroid, ensuring identical software. The phantom button presses are gone! So, it seems the button presses are indeed a hardware failure, not software related. If you have phantom button presses, get a replacement phone and save yourself some grief.

Dammit. I assumed it was software since this only started happening when I switched to froyo. The kernel is buggy and I figured this would go away once the devs bring us ones from proper source.
I guess my days of not safely removing from PC are catching up to me.

The only thing I've noticed on my phone is my power/sleep button sometimes randomly takes screen shots instead of going to sleep, which I thought I read was the back key sticking, is this similar to what everyone is experiencing with these phantom button presses? Mine isn't backing out of programs or anything?
I've had these phantom button presses on mine on and off since I got the phone. Even before I rooted it. I always assumed it was because the soft keys were dirty/oily and were incorrectly registering touches. Wiping off my phone has always taken care of the problem.
My fascinate has infrequently done this over the last several months. Today, the stupid thing started pressing the back button every few seconds. Rebooted several times. No improvement. Switched kernels. No improvement.
I decided to try to see if this is software or hardware. Rebooted to CWR and left it setting on one of the options. Right now it has been setting for about 10+ min and no random back buttons have been pressed. My thinking is, if this is a hardware bug it should have selected the highlighted option since the back button is used as the select in CWR.
Anyone have any ideas?
I think I might try a clean reload starting from the stock ODIN when I get home.
Phone is rooted and running SC 2.9 Voodoo Kernel, voodoo disabled.
I have this issue really bad ever since upgrading to Gingerbread...
If I use Odin to flash back to the Stock Verizon 2.2 the issue disappears, but if I flash any gingerbread, doesn't matter if its VGB or one of the CM7 nightlies, the phone presses the back and menu button pretty consistently and also if you remove the battery for any reason at all, it loses or forgets a lot of apps that you may have installed (Live Wallpapers for instance) and also takes 3-5 reboots or power down cycles to finally boot up NOT in Safe Mode.
Not sure what the hell is going on, but I may have to just Odin back to Verizon stock 2.2, root it and live with the bloatware
Oh, and this issue is persistent from my original Fascinate to the refurbished replacement that Verizon just sent me. So either they sent me a refurbished phone that has the exact same symptoms or its an issue with Gingerbread and the Fascinate.
Any suggestions?
Anybody? Bueller?
Could my stock Samsung 16gb memory card be causing this? That's the only thing that was carried over from my old phone that had the button press issues to the new refurbished one.
Has anybody made that correlation?
Bump,
Googling about this problem, it seems this is a wide spread problem with Fascinate and few other Samsung phones. No one knows of the real problem nor a fix.
It is unacceptable for Samsung not handle this problem which sounds like it's hardware related for this long.
Any more input guys?
I was about to buy the Samsung Fascinate myself but this sounds like a major problem to me.

Random Reboots AOKP

Hey guys. this isn't my first rodeo so no flaming.
I keep getting random reboots on my phone. It happens about every 15 minutes to an hour. I've flashed stock and did a full factory reset. I've tried new kernels... What are my other options? This is starting to get on my nerves
My suggestion is going back to bone stock with no adjustment.

No hardware accessories and no undervolting. I made sure to stop the UV when the reboots started occurring. I'm by no means a dev, but i've been around a while and this just baffles me.

It could just be a bad battery. I'd suggest wiping and flashing back to stock. If the reboots continue, you can probably get AT&T to give you a replacement.
I'm getting the same problem as you. Before I started flashing (I'm still seeing the problem in AOKP, too), it was happening on the stock rom. I'm going to flash back to stock and see if that helps for me.
By the way, I think it's a hardware issue also. It seems like the reboots are more frequent when I'm holding the phone or when it is in my pocket, maybe the contacts in the battery are the problem? It happens if I just sit the phone on my desk also, so I know I'm not accidentally holding the power button
EDIT: 1
Okay, after flashing back to the stock rom, the problem persisted. I just picked my phone up and it turned of as soon as I lifted it. Have you noticed that lifting/touching is related also?

Power Button Failure

So I was using my camera LED as a flash light yesterday for a really really long time. Like 80% battery to 3%. Toward the end my power button quit responding so I had to pull the battery to even wake up the phone (could have called it but I didn't know it was the power button). Anyways it's still under warranty but it's rooted and I have Phone Bricker 2.7 installed. I don't mind sending it in to Samsung for a warranty (I got it late September or whenever the I777 came out last year) but I think I need to order a jig first and reset the flash counter and reflash stock OS (which I can find on the forum).
I was seeking alternatives to make it usable because I'm going to AZ this weekend and would prefer not to have to temporarily return to my old Nexus One while I order my jig and stuff. I found an app called like AnyLock or something.. (I removed it already). It would allow me to use the volume rocker to wake up the display but it seemed like it only worked if the phone just recently went to sleep. After 10 minutes or so the button wouldn't wake up the phone and I'd have to plug in a charger or something.
I purchased WidgetLocker which claimed to allow this sort of thing too. Set it all up and it did the same thing.. wouldn't respond after some intermittent time after the display timed out. Well that and it's also waking up the display automatically (even sitting here on my desk, not even touching the phone) a three or four times a minute.
Any suggestions on something to allow for temporary wakeups? I was running CM7 on my nexus 1 and I was able to wake using the trackball. Phone Bricker doesn't seem to give me any options like using the volume rocker.. I should be able to use the CWM app to reboot into recovery mode without having to do the power button thing to flash a different mod if maybe CM has a volume rocker option.. or any other mod.
I don't have much help for but can tell you that aokp has volume rocker to wake screen option.

That is exactly the kind of help I'm looking for! I love Phone Bricker but it's the only mod I've tried on this phone.. I'd much rather flash the OS than mess around with the N1, I'll save that for when I'm ready to ship it in for warranty.
Same thing happened to my old i777. Temporary fix is to use go launcher and go locker. Go into setting for go locker and set screen wake when volume is pressed. Att gave me a new phone with no issues

You guys purchased them as new, rip them off, beat them up, flash/install custom ROMs/kernels. Screw up big time then return them and get the new ones.

I didn't drop it or anything! I might have shaken it up some using it but nothing terrible.. Anyways if it was getting the phone too hot by running the flashlight app too long, I could have done that with the stock OS and a flashlight app from the market so I'd still warranty it I just wouldn't have to do more work to cover my warranty voiding tracks. I just wanted to post all info I thought could have been relevant because who would help me if they had to ask me a ton of questions first? But you know, I just did the go locker solution jthatch12 suggested and it's working fine.
I don't know a fix, but I have a potential workaround. CM7 and CM9 both allow you to wake up the phone with the volume keys. An app called Virtual Button Bar will allow you to put the phone to sleep from any screen (as long you're rooted). It costs a couple bucks but it works really well.

When you get around to unrooting your phone, do the mobile odin reset back to stock. That'll put your phone back to stock and in a bootloop. Then take your phone back to att and tell them something failed during the update to ics. Worked for me. My power button stopped working randomly one day for no reason. My phones are babied.

My power button stopped working today. I set it to wake in volume rocker. I can't restart my phone or boot into recovery anymore. My phone is out of warranty, so I can't send it in. Any idea for a fix?

i had a faulty power button recently and it would keep restarting my phone basically anytime i touched it. i flashed 3 different roms on it to make sure it was a hardware problem and searching around i found that the phone is basically broken... luckily i was still within my the year for warranty so ive since replaced. im not sure if your power button just has stopped working all together or youre having other issues with it but from my experience you should start looking for a new phone
Damn, that sucks sorry man.. that's happened to me 3 months ago, luckily I still had the warranty...u might have to fork out the cash a buy a new phone... when is your next upgrade?
Next upgrade is in May. Oddly enough, when I took the back off to see if anything was visibly wrong, I tested it by pushing the actual switch (not the outside button cover) it worked. Then after putting it all back together everything works as normal. Hopefully it stays that way.
