Is your EVO soft resetting automatically or on its own?

Mine just started to after lunch today. I've had it on the desk and saw it restart about 3 times in less than a 15 minute window.
How do I know this just started and it hasn't been going on in my pocket? Well over the weekend I would have heard it reset (since it's not on silent/vibrate like it is at work). It also significantly drains the battery more if you are constantly soft resetting it/turning it off and on.
So is anyone else having this issue? I need to figure out if it was just a freak occurrence or if something is wrong with it.
I did NOT root it, running everything stock - I did some updates on some apps I have installed but no new programs installed in a couple of days - again this just started happening today in the last couple of hours.
And besides email and messaging, I'm not running anything in the background like Pandora or eBuddy, so I don't think it's a program causing it to reset.
Edit:
Not sure if this is the best category for the thread, but I could not find any threads similar to this besides the battery issue in general. Apologies if this thread already exists somewhere.

No uncalled for restarts here. Open the back, pull the battery, check the contacts? Is it plugged in when it does this? Try padding the battery with a folded piece of paper between the door and battery to ensure a snug fit. If it still does that, time to go to a store.

@Jye75
Thanks, I have pulled out and looked at the battery. I have that Seido case they were slangin' at Best Buy on it, I don't think there's an issue with the contacts.
One weird thing is during one of the automatic restarts, the phone made the start up sound. I had the phone on vibrate and the start up before that (and after when I manually restarted it) did not have a tone. Very odd... perhaps it's possessed.

Odd indeed... drop by a Sprint store, would be my next move.

It happened to me two times today since I did the full root last night. The last time it happened, I clicked on a input field and it restarted...

I had the issue when I turned off "enable always on mobile data"...turning it back on stopped the resets.

Probably just a kernel panic. I would not worry about it too much. It's happened to me on my Hero, and on my Evo.
For comparison purposes, how often does OS X Kernel Panic? How often does Windows BSOD?
Android is rather new technology in comparison. Yes, it runs Linux, which is rather mature at this point, but it's built with a lot of new technology, which may not be as mature as the stock kernel itself.
/two cents.

It reset about 8-10 times in less than 2 hours. More than half of that time the phone was in my pocket and not in use. I hardly got a signal inside of Walmart so it's not like I was using it that much in there.
I have set the data to be always on and hopefully this will help...
I appreciate all the help guys!

I had the same exact thing happen to me beginning this past weekend. It was driving me insane since it was rebooting every 30 minutes or so. I noticed it started happening more so when I did not have good signal. In any case I came to the conclusion it was all the tinkering (root part 1 and custom ROM) I've done with the phone so I wiped it last night and started from scratch (root part 1 and 2 and custom ROM). No reboots yet, but seeing your post concerns me since it's not the first post I've read regarding this issue. I'll keep you posted if mine keeps doing it. I really hope it's not a real issue, getting a replacement does not seem like it will be an easy process at the moment with them constantly selling out.

Thanks for the input. Your concern about the difficulty in getting a replaced unit due to them selling out is EXACTLY why I'm trying to figure out if this is a software glitch.
I'm also glad you pointed out that it tended to happen when the signal was ****ty. Last night I enabled the data always on (it was on by default and I turned it off earlier in the weekend) and I haven't had a reset yet this morning. Of course I've also been in good coverage areas. When it kept resetting like mad last night it was inside of Wal-Mart, and they have some serious shielding on their building or something since I rarely get a full or even half signal in there regardless of carrier or phone in past experience. A lot of friends on Altell/Verizon beg to differ with me though.
I'm thinking if they're connected, the fact that a weak data signal contributes to the device rebooting is really odd; the only time I can think of why a phone should reboot on its own is the OS crashes (or some app takes up ALL the available RAM, freezing it, then crashing it) or it overheats (but would seem to turn off rather than reboot). I had a BB Curve that did this at one point so I had to clear the cache all the time.
Edit:
Actually, I realized when it started to happen it was at work where I have excellent reception. Hmmm... well at least it hasn't reset on its own this morning so far (so far meaning 30 minutes).

Well for what it's worth, mine was also doing it in good signal areas as well. It just seemed a lot more pronounced when I was getting bad signal. Anywho I reread your original post that you are running stock software so let's see if it keeps occuring for both of us regardless of the differences in software we are running. I also still have "Enable data always on" off.

Sounds like a plan. Still no problems so far with data always on.
FWIW I also did the battery trick by switching the phone to CDMA auto from GSM auto. Supposedly you have to do it everytime you boot your phone, and it's supposed to help with battery life. Thread here:
http://forum.xda-developers.com/showthread.php?t=700601

It has to have something to do with turning off always on mobile data. It goes away when it's on, but then comes back when you turn it off. I just did rooted and unlocked nand protection on my phone last night and turned off always on mobile data and haven't had any reboots yet. Then again, it took a little while for it to start resetting last time so we'll see I guess. Could just be some glitch in the software that putting a new rom on has fixed...

Mine had been the complete opposite, I have had data off, and when I turned it on yesterday it started reseting, I turned data back off last night and have had no more problems...

I had this happen to me while I was trying to talk on the phone and use google navigation at the same time while running the Overclocking widget to throttle my cpu to 285mhz when the screen was off. Whenever I turned off the screen my phone would reboot.
My guess is that there some issue there where the cpu cant keep up with the heavy usage, locks up and forces a reboot...
I've since gotten rid of the OC widget, rooted my phone and installed a custom rom. I've not had it happen since, of course I havent tried talking and using google nav yet.
I've also noticed that advanced task killer caused the htc sense launcher to reboot (force killed) every once in a while... I've gotten rid of that too...

happend to me while talking on the phone twice, it was weird i could hear him still talking the entire time it was rebooting, up untill the OS actually launched...Im gunna try and kill set cpu, how many other people have this running while its rebooting???

This happened to me today, in-call. My phone has reset 6 times since then off-call.

Alright un-installed setcpu and it still resets. I'm now trying to shim my battery to see if its a loose connection. I gotta figure this out its driving me crazy...
UPDATE: still hapining with battery shined, tried both data sync on and off, installed setcpu, all to no avail... maybe I will try a hard reset... I remember on my kaiser this started hapinin and it was a bad nand flash, but I'm running stock with unrevoked... so if anyone has any ideas I'm wide open.

Running Toast's root has stopped it for me as of today. If that actually had any effect, I have no idea...but no resets yet with always on mobile data on and off. Maybe flashing the rom again helped...

Wow dude I'm sorry to hear you're having that much trouble. I'm on step 2 of part 2 of Toast's root method but running into major issues. Since I did step 1 (and before that I enabled data always on again) I haven't had a reset issue.
For the record, my Hardware version 2.
Do you guys think this is a widespread or isolated issue? I'm surprised it hasn't happened more or less, in other words I figured there would be either a lot or hardly any comments about it. This medium sized number is interesting.

Random Reboots...

Hey everyone, I looked around and didn't find anyone having my particular problem, but If I put this in the wrong place, or someone has already solved it, just let me know. Don't want to waste your time!
I got my DINC the day they came out in stores...the first one my local store sold in fact. It was working great, but I hated the bloatware and the fact that the Bluetooth stack was not up to date...couldn't connect with a new hands free speaker phone I just bought (Parrot mini-kit slim). I had occasional random reboots, but not too many. Once or twice a week maybe.
So when the unrevoked one-click came out I tried it. Worked great.
Then I started trying ROMs. With everything I've tried I get random reboots...a lot of them. Sometimes it reboots once and works fine for a couple hours. Other times, it will loop until I do a battery pull. When it loops it will sometimes make it all the way to the lock screen, sometimes it will only make it to the boot animation, and sometimes it won't get past the white HTC screen.
I've used a couple different nightly builds of CM6, with and without google apps. I've used Skyraider 1.8 and 1.9 with and without sense. I've tried "touch of photons". Same results and activity on all of them.
Last night I gave up and downgraded to unrooted 2.1 with sense...factory fresh. I reformatted my SD card with the phone, reformatted the phone storage, and I've done factory resets. It still isn't working right.
At this point, I'd be happy to get it back to pre-Unrevoked and just wait for the official OTA Froyo which is supposed to come out soon. Rooting and using a stable rom is fine with me too. I just need a phone that works consistently.
Any ideas? I'm pretty desperate.

sounds like you needed to return it and get a new one since it was doing random reboots from the day you bought it.
have you used any of the hydra kernels to try and OC it, the 1.15 OC would cause mine to reboot. a good stable rom that i tried was JagerRom, 1.7.4 is without sense, and chocolate is with sense. don't try the OTA one because that is for people who updated to the OTA leak and im going to assume you aren't one of thoes people. haha

hope this helps

Thanks Stroupified...
The weird thing is that the reboot issue wasn't that big of a deal before I rooted and started flashing roms. It happened, but not enough to be a problem.
Does the camera and camcorder work on Jager?
Does anyone know if there is something that could have gotten messed up with unrevoked or the roms I tried?
Is there another downgrade method I can use? I just installed the PB31IMG.zip you can find in a few places out there...is there a known reliable source for the downgrade zip?
If I can avoid fighting with Verizon on this I'd like to. I'm obviously outside my 30 days, and I don't want to wait a week or 2 or three or more for a new incredible (if I can convince them to get me one). I'm not even sure warranty or Asurion will do anything with this kind of a problem either...I fear I'm stuck with a $500 reboot roulette machine.

re
i have gone through 4 incredibles.
they all exhibited the same rebooting issues... completely stock with NO installed apps.
I have also tested the phones with 2 different batteries and with different sd cards and no sd cards installed.
I had done factory resets.
I get a ****ty cell connection where i live, -100 to -96 db.
Its looking more like a tower issue..

I also have had a reboot issue. I rooted the phone the day I got it and installed a senseless rom. It worked perfect the 1st day then started into a downward spiral of reboots till it went into a full boot loop. I did a nandroid back up of the original rom. No real issues since. Im still rooted and have only had one random reboot in about a week that I know of. I know the first issue was because of the rom but what causes the random reboots. Is it aloss of signal? Im a noob so Im just trying to get some insight.

Im on #2
I got my 2nd Incredible on Friday. Prior one would just get hotter and hotter (possibly due to signal issues) until it would enter a reboot loop. Hoping # 2 fares better.

ya everything works in jager. but from what everyone else is saying it seems like it could be the signal (or lack there of) that's causing the reboots. have you tried the hybrid prl? it uses the verizon and altell towers instead of just the verizon ones. i haven't tried it because im in cali and there aren't any altell towers near me, but if your stuck with the phone you might as well give it a shot if you live in the supported areas. good luck man.
Link to PRL thread:
http://forum.xda-developers.com/showthread.php?t=723829

If you don't have problems with signal don't bother with the hybrid prl... it kills your data speeds because it switches you from Verizon data network to Sprints data in most areas. I know in the Carolinas phones randomly reboot a lot because thats Alltel country and phones don't work properly without the hybrid. But down south its mostly Verizon. Out west Texas/Ok is mostly Alltel.
But man honestly - I have the same issue on custom roms. My stock Sense rom does fine though. Sometimes I'll be on a custom rom typing a text and the keyboard just freezes and its over. lol nandroid time to me - I can't take the reboots but hate not having the features of newer software.

re
i have tried the hybrid prl and it did not help my rebooting issues.
i have also tried switching to the the cdma codec to -b the higher quality compression... with no luck in fixing the reboots.
I have also made sure there was not an issue with an app causing it, i have tested mine with a clean / factory reset with absolutely no apps installed.
I have had 100% good luck with the leaked ota update, the one upped the camera to 720p recording as well as a hand full of other fixes, and not once did my incredible reboot or crash.
I'm pretty confident that htc has fixed this issue for me, once they drop the 2.2 update that everybody seems to be speculating will be released in a handful of weeks.

Thanks for the input everyone, and I'm sorry others are having the same problem.
I went by my local Verizon store (actual Verizon store, not a 3rd part dealer) and told them my phone was rebooting repeatedly. They didn't even touch my phone...I was out of there in 5 minutes with a FedEx 2nd Day Air confirmation number for a new handset. And my wallet is intact also. I'm rarely impressed by Verizon's customer service, but this time...man... Between the new handset and the impending 2.2 update, I hope to be in good shape.

Same EXACT thing happened with me and telesales. No scripts, no hard reset, no task killer; NOTHING. Said "my phone gets hot and reboots" and they said (last Thurs), let's get you a replacement overnight so you can try the new one out of the weekend. No muss, no fuss. Got here 10:30AM the next day, and my evil super-heating 4-to-13-reboot-try prone phone is going back.

I don't believe towers/signal would have any effect on shutting down or booting. Basically once you're on a current PRL, you really shouldn't even have to update it. Unless you're having that poor service deal where an Alltell/Vzw hybrid would benefit you.

[Q] Singal/Radio affected by ROM???

Not sure if other users have seen this, but I found something interesting last night...
Since assurion screwed me and replaced my stolen amoled with slcd my options were somewhat limited in ROM selection. Skyraider was my goto previously.
I have been using Jaeger since my replacement got here about a month ago, and consistently have been having signal/radio issues. Data would randomly stop working, airplane mode would not work to recover, no signal at my desk, etc.. Battery poppin was a standard.
Last night I installed INCRom, and while the transitions & keyboard are driving me nuts the ROM itself is super fast, feels like a new phone. The reason for the post is, for the first time since I got the phone I have been able to wifi tether for longer then 4 mins without Data being disconnected. I was intermittently receiving e-mails in the train and full signal at my desk. I'm wondering if this somehow related to the ROM? Obviously no scientific testing has been done.

Ya, this problem has been poppin up where 3G would just drop out. If you really like Jaeger, then try this fix. It might help, but I haven't personally tried it out.
[Fix] 3G Drops

Thanks... that's what I get for not keeping up... I'm going to take the weekend, if my kid can keep herself busy with her gifts to write my own...

Galaxy Nexus Worse After 4.0.4

I have a Galaxy Nexus on Sprint. I got it a couple days before the 4.0.4 update, and for those couple days, it worked great. Calls were coming and going, no browser issues, even the GPS sync'd up in seconds (I heard about the issues so I put it through some testing).
Fast forward a couple days and I get 4.0.4. First thing I notice is my web browsing slowing to a crawl, then eventually, just stops. I would click anything or go anywhere, and the progress bar will barely move and just stay put. This did not happen connected to WiFi, only 3G. I reboot my phone, and all is well for another few hours. I don't always use my phone at all times, so I don't know what causes it. I've had to reboot my phone twice yesterday because of this issue.
The next issue was the GPS. I was going somewhere with my wife and figured GPS'ing an address wouldn't be a problem. Well, after about 3 minutes I figured it was like the browsing issue and rebooted the phone hoping it would work again. Nope. We loaded the address up in my wife's Samsung Replenish and were on our way. The whole time my phone was trying to get a GPS lock after a fresh reboot. I even threw my phone on the dashboard so it had a clear view of the sky. The GPS never did sync after the 15 minutes or so it took to get there.
Today, I just discovered ANOTHER issue! I was talking on the phone to my doctor's office, when I heard a few clicks, then it hung up. I thought it was my doctor's office that tried to transfer me and goofed up. I try to call back and after a few rings, I get call cannot be completed as dialed. Still, I thought it was their end. I call again and the recording comes up and plays for about 5 seconds, then cuts out again. So I finally call on a landline and all was well. After I was off the phone, another call came in to my phone and I answered it after the second ring, and it cut out immediately. My wife tried calling later after that, with the same results. After calling again, I was able to hear her after about 5 seconds (I waited longer than that last time).
I'm coming from an EVO 3D (EVO 4G before that) and it had it's quirks, but at least I could hold a conversation and use the web browser reliably. Being basically a vanilla Google Android handset, I had high hopes that all my worries and woes would go away. Now? After being pro-Android since my Samsung Moment, I'm starting to think if I should get a damn iPhone. As much as I dislike Apple and what it stands for, at least their phones "just work".
Anybody have anything I can or should try? Should I just toss this phone on the shelf until Google figures out what they're doing with this handset?

sounds like sprint in your area is having problems.
i doubt it would matter if you had a iphone or not.

My wife isn't having ANY problems with her old PoS Replenish. A lot of friends of mine have Sprint and nobody is having problems that I've heard. As soon as I reboot it when I have browser problems, it works great again, until later.

Flash a custom rom.
Or if you don't want to have a custom rom then flash the factory image.
Maybe something went a bit arse-ways with the ota.
that shouldn't be happening, its not normal, 4.0.4 made the gnex better than it already was!

I did a factory reset and the first call I made was dropped. Guess I'll put a custom rom on it... I shouldn't have to though

might something with the radio if everyone else around is not having problems with sprint. factory reset is not the same as reflashing the 4.0.4 images. try and reflash the stock 4.0.4 images.

I'm on my second device, sprint swapped mine out because my data was just crawling, and I came from T-Mobile and they don't have fast 3G and it felt like I just switched to Dial-Up. They updated the device in-store to 4.0.4 and it was fine yesterday and this morning Pandora kept stopping and buffering. When I got to work I rebooted and ran a speed test and I was getting 1400-1700kbps and sub 400ms ping, which IMHO good considering I don't get great reception in our datacenter. Now 4 hours later I'm down to 100-330kbps and ping of 1000ms plus... even after reboot...

Probably Sprint-version-specific problem or hardware problem of your phone.
I use a GSM Nexus on tmobile and I know people that have the Verizon version. Everyone noticed significant improvement after going to 4.0.4.

No Network Signal After Flash to 4.1 on Verizon Galaxy Nexus

I just updated to 4.1 and can't seem to get a network signal on any of the ROMs I have tried. Anyone else had this problem or found or know of a solution?
Thanks.

Was this an OTA uprade? If you did an manual upgrade, you should make a backup before going forward.

Are you sure you used the correct ROM? Cross-flashing between a Toro/Maguro/Toro+ will often have the phone but up but with the radios not working

did you check your apn?

I just bought this phone on Thursday and the bestbuy rep had the same problem on two different phones and had to call the Verizon help desk. She managed to get it working and of course my signal went in and out as soon as I left the parking lot. I went home and immediately rooted and flashed 4.1 and had the same issue. I was on the phone with tech support and they couldn't find the problem.
I then did a quick search online and found that this is a common issue. The problem is that when updating to 4.0.4 the galaxy nexus has a hard time with the 4g connection. It then drops to 3g and then it realizes 4g is available and switches back just to start this never ending cycle. This causes a signal to be held for seconds at a time before dropping completely until it switches to the other.
The temp fix is to disable LTE and run your phone on CDMA full time. This worked for me and I have constant signal everywhere. Eventually I know a patch will arrive so I'm content with 3g for the time being.
What puzzles me is how come this doesn't happen to everyone? Its a big enough issue that I found the solution within 3min of searching for a fix but not big enough for Verizon to be aware of.

What puzzles me is how come this doesn't happen to everyone? Its a big enough issue that I found the solution within 3min of searching for a fix but not big enough for Verizon to be aware of.

I have the same issue. it burns your battery as well by switching back and forth. I used to leave my nexus uncharged at night and the sleep mode would allow it to only lose a a few percentages but now if i leave 4g on with 50 percent battery.. Its almost alway dead when I wake up

Sad to say I have the same experience
The story told by mclaughlin47 is almost exactly what happened with me. Even rooted and running BAMF Paradigm 2.1, I still have the same problem. If anyone knows of a way to fix this, please let us know.
I can't believe Verizon isn't aware of this problem. I actually had better battery life and signal with my Thunderbolt running Vicious ROM. I may just be returning mine if I don't hear of a solution soon.
Thanks for any help, cause this is ridiculous!

I am rooted now, but even on stock ICS I was getting a problem where my radios just die. Requires a reboot to fix. But when I was seeing it, they always looked fine. You don't know they died until you try to use data or make a call.

Do you still have your imei

I saw the same issue with ics and jb roms. Tried several radios but always dropped data and voice when using 4g. From what I've been reading, it's a hardware defect.
Mine also works great and stays connected all the time when I leave it in cdma mode. Went back to my rezound since 3g mode there at least still let's me use data while talking on the phone. I like showering in as much radiation as I can

Reflash the radio and the cdma radio. Samsung and Verizon Wireless both claim that hardware defects are not known issues.
Which hardware revision do you have? (looks on the label on the back should be 11.11, 11.12, or 12.0.)

i have 12.01
will try reflashing the latest radios

Have the same exact issue...just upgraded to a jelly bean Rom and my data drops completely and I barely have a signal, did a super wipe (radio-rom-Gnapps)...and went to my old rom of ICS and I still have the same problem...but for the most part I barely have any type of signal and calls are dropping, called Verizon and they told me something about a switch, and that there is no problem in ur area....I just called last night, I'm gonna call back today...wish there was a solution ...also tried that 3G switch I just read earlier and I still have a poor signal

Any updates? I'm having the same problem

Hi,
I'm having the same issue. I've had my Nexus for about a month now and have had nothing but horrible signal issues, while my old Droid 2 gets fantastic signal.
I'm using the latest Bugless Beast 4.1.1 with the latest radios that were released today.
People have mentioned it being a hardware defect. I'm assuming I should just go back to stock ICS and go into Verizon and exchange it for a different Nexus?

It may very well be a hardware problem, but my thought was a SIM card problem for the reason that rebooting often does not solve the problem for me. I have a passcode on my SIM card, so if my phone doesn't ask me to enter the code then I can assume it doesn't see the card. This often happens when I encounter the loss of data problem and reboot, and I usually have to remove the SIM card and fiddle with it a bit and put it back in and then it reconnects.
So I went to the Verizon store to try and swap my SIM card and they wouldn't give me a new card, saying that it's a known software issue that Samsung has already attempted to fix twice and they are working on another OTA update. I obviously made a ruckus about how I'm paying for service I can't access and I want a different device, blah, blah, blah. Basically he was incredibly unhelpful.
I've been on ICS AOKP and recently switched over the CM10 JB and that's when the problems started for me, but I switched because some type of battery issue (it lasted about 3 hours for a few days) caused my phone to reset itself and erase everything so it seemed like a good time to upgrade. So I may have unique hardware issues going on but according to vzw it is software-based. I'm not sure if this is something that can/will be addressed in a new nightly if that's the case.

PEOPLE, IT'S NOT A HARDWARE PROBLEM! IT'S SIMPLY A RADIO.IMG PROBLEM! A LOT OF PEOPLE WHO IS ON ICS, BUT FLASHED LATEST RADIO ARE SUFFERING FROM THIS!
What you can do is just flash to a older radio image. Not that hard. Will this stop the OTA? Probably, but you can either flash the latest version back or just manually flash it.
Have a good day.

I got mine the first week of Aug at Best Buy. The first one I got had all the problems described above. Radios dropping out and dropping every call I made. I returned it the next day, and the sales guy told me he was 100% sure it wasn't the phone. I asked him to exchange the phone and the card because I couldn't use a phone that couldn't make calls. He did the exchange, and the second phone was actually worse. Most of the time, I could not even make a call. So, the next day I took that one back. They gave me a third one that worked great for a week, then I started getting a no SIM card error message. The phone would reboot and work again for about 3 hours, then repeat error message. I took the card out, wiped down all the contacts with a soft cloth, and I have had no problems since. Great reception, no dropped calls. Great phone. I don't know if it is hardware or software, but I would keep returning the phone until you get one that works!
Once again, what is the point of having a phone that can't make calls.
