My buddy has had the same problem. I had him do a hard reset and it was Ok for a day and a half until he setup his email again...and it began rebooting in his pocket like before. His problem seems to be occurring due to his email setup in the Mail app.
Anyone else narrowed their problems down to this?
To update, he finally went and exchanged it...haven't heard him complain about the restarting problems since, so I guess his new one doesn't suffer from the same issues.
I had random reboots when I first got it. I did a factory reset and formatted the sd card and that seemed to help some...it still rebooted, but not as much. Found out that when I went to the factory task manager (it's listed in your loaded apps) that I was short on memory for some reason. I did a kill all, and recovered about half my memory. I still have to do a reboot every now and then, but it's no near as bad as it has been. I've been to the Sprint store and talked to the tech and he said to keep an eye on it for the next few days and if it still does that to bring it in and replace it. I think that's the course I'm going to take. As far as the icons going back to the stock android icon upon reboot, that's a common issue for the apps that have been moved to SD card, and the easiest way to fix it is to go to personalize and change your Scene, then change it back to the one you had and your icons will reappear (not my discovery, but don't remember who to give credit to since I've been reading a ton of posts and forums about this and other Evo 3D stuff).
Bought Two of the HTC EVO 3d Phone: Issues with both!
Bought one for myself: Mine automatically reboots itself for no reason at all, sometimes twice a day... this has been going on for a solid week. And I bought it one week ago today.
Bought one for my wife: With hers the screen just goes black and the phone dies...sometimes twice a day! Have to do a battery pull to get it running again.
Both phones will be returned shortly unless an update fixing these issues is pushed out.
Love the phone, but what a pain to put up with all this.
I called sprint support, told them my phone randomly reboots and freezes and the steps I've done to correct it. No questions asked, no further troubleshooting...I was given an exchange. Just gotta go to the Sprint repair center to exchange it.
Just got back from the Sprint store. The rep has ordered two new phones for us due to this rebooting issue. But the phone is on back-order now, will take about 5 days.
What I don't get is why mine can go for days at a time without a lockup or spontaneous reboot? It was worst, by far, the day I got it, then was stable for a few days, then over 4th of July weekend had problems on Saturday and Monday, and since Monday, it has been rock solid.
But I have buddies who have yet to report a single problem with their EVO 3D. And these are definitely power users! So seems like any deviation from perfect stability is a problem.
I know, second guessing myself. Oh, well, my replacement phone is on order.
For clarity, we're talking about reboots that happen without our intervention, not reboots that we initiate.
Yes, I realize that. I'm talking about a manual reboot to help clear up the memory. I've been watching the memory and if it gets too low, the phone starts to hang up and randomly reboots itself. I haven't had any problems for the last week, the memory seems to be more stable now. Not sure if it was an app that was causing the issues, but everything seems to be fine now.

I thought Android automatically closed out background apps once memory got low? And quantify "low"?
Just received my EVO3D - I have had more random reboots than I can count since activating and updating (4 HTC updates) this unit.
Note that I do not have any apps installed on this phone. I have Facebook account, google account and a mail account set up on this unit.
Some observations that I hope will lead to some resolutions:
When connected to WiFi - phone contstantly reboots for no apparent reason. Simply wake the phone up and it reboots. Reviewing calendar - phone reboots and etc.
Airplane Mode - I do not get very good reception while in my office so I put the phone in airplane mode and turn off the screen (sleep). If I wake the phone up every couple of minutes, no issues. If I let the phone sit for more than a couple of minutes, the phone becomes unresponsive and the only solution is a battery pull.
I have reset to factory 3 times already and the same issues are present after each reset.
I am willing to provide more of my phone settings to assist in finding a solution to the issues I am having with this phone. I really want to like this phone but it is a challenge at this point.

I replaced my 1st phone since it had dead pixels. The 2nd phone I had worked good for a couple of days then started rebooting every 6 minutes. Very annoying. I took it to the store and they said it was a bad battery, so they gave me another battery. Charged it up at home and then the phone started rebooting again every 6 minutes. I did multiple hard resets before I took it in the 1st time and nothing seemed to fix it. When I took it back again they exchanged it with a new one. No problems for a week now.

Guarantee it does - you can monitor your logs in Android System Info (Electric Sheep) and see it happen (if you like watching paint dry ).
Low memory limits for that are also displayed by that app.
There is a set low memory limits, increasing in severity, so that the operating system can always recover.
A rogue app (by bad design or bad install) can do nearly anything.
When hard resets and app removals don't cut it, replacement is seeming the way to go - it's a hardware issue. I've seen this happen on PCs with bad memory chips - could be a similar situation here. No OS can manage bad memory.
I have two evo 3d's one has the problem and one does not have the problem. What happens is the screen goes off and you cannot get it back on without pulling battery the phone is not locked up if you call the phone it will ring and you can get the cap buttons to light up if you hit the power buttuon a couple of times if others could test to see if the phone still rings I think they will find the same so my conclusion is its the screen not the phone locking up. I have done a hard reset and I have tested to make sure it not a installed app causing the problem it does with factory installed apps. I have exchanged the device and the new one is doing the same thing. I have checked to see if there the same harware versions 0002 and they are. I remember the evo 4g had a few different hardware versions such as different screens.

As EarlyMon stated, Android does close out background apps when the memory gets low, but to the best of my knowledge, I had a bad app or two. Again, I can't say which one(s) they were, I've only recently been limiting myself to the apps I know are good and what I've needed. Now when I install more apps, I am keeping track of how they change the way the phone acts.
As far as what I would quantify as low would be around 15-20% remaining.
The phone seems to be running pretty stable now and has for the last week. I'm well within my 30 days for an exchange, so for the time being, I'm happy with the phone and don't see the need in an exchange unless it starts to act up again.
Dangit. My replacement phone just had a lockup. Had to remove the battery to restart it and get it to respond. Major :-(
EDIT: Locked up again less than 1 hour later. :-(
Both times, it was just sitting in my phone case.
The only other problem is, about 1 hour after I got this replacement phone, I noticed the CDMA radio was switching on and off about once every 2 seconds. At least that's what the display said--it alternated between a 4/5 bar reading (was close to a tower) and the X on the top left of grayed out bars, indicating that it has no signal (?).
Rebooting it did not fix; still alternated between signal and no signal once every 2 second.
Fixed with a factory reset, and I even did it using the procedure where you hold down the volume down button while powering it on. Had to disable the fast boot to get that to happen.
That was all last night. It's been rock solid until 1 hour ago today.

So I've had a few lockups and reboots since I posted last. It did the black screen with lit up buttons thing like twice and had a couple reboots. Maybe it's the battery being too hot, cause it does get a little hot sometimes (plus that would make it one problem and not two, which I would prefer)
also experiencing random reboots & black screen/4 lighted buttons (BS4LBs). started a few hours after i installed both hand cent app and updated tunewiki. was in my pocket during a long commute home, got fairly heated up (first time that's happened, i think), and i noticed it was randomly rebooting. once i tried using it i started getting the BS4LBs and had to do battery pulls. first i uninstalled those apps, which didn't seem to help. then i noticed that when i opened task manager, nothing at all appeared ("Settings" or "Task Manager" or whatever used to appear), memory usually seemed relatively low (~400mb), and phone was particularly prone to the BS4LBs. after a few reboots i decided i was just going to do a factory reset so i started going through apps to save any important settings. i only loaded a couple, including FPse. after this, i noticed that the system seemed a little more responsive so risked going into my task manager. lo and behold, items were listed again. memory was still low, but phone was more responsive.
two more situational facts: 1) i live in phoenix suburbs, which have particularly awful sprint towers, which cause me to lose signal very, very frequently, and i am often switched to roaming mode. 2) i tried at one point to download an alternate task killer but the market crashed and, along with it, i started receiving various system service crash messages (phone.android.com and some such). task bar eventually disappeared and wouldn't be force stopped/restarted until hard reset.
i upgraded from an htc hero which gave me all manner of headaches to this, which is rapidly on its way. if this doesn't get better, my next upgrade will be a $30 phone, no doubt. i guess i'll wait for the next OTA updates or ask the reps if they'll do a replacement. technological innovation is fast out-pacing QA. what a pain.
Isn't it true that apps are generally not loaded until invoked? Sure, some apps may be invoked automagically, like apps that respond to system events, but barring those, seems like installed apps shouldn't be a factor unless they are running?
that'd be interesting, nova, because the problems and drops in free memory didn't occur until after the installs. i can't think of anything else that was different
My first EVO 3D had routine problems with random reboots and lockups (where battery R&R was required to get it to respond).
Now my replacement EVO 3D is doing the same. Chronology:
Day 1: get the new one about 4:45 PM. At around 6:30, in area with great signal strength, and find that phone's signal strength indicator is bouncing between 4/5 bars and no signal (all bars grayed out with an X superimposed). Reboot had no effect. Had to hard reset to fix. This was the hard reset where you disable the fast start and hold the volume down button while powering on.
Day 2: While idle (either in belt holder or sitting on a table--cannot remember), phone became unresponsive and required battery R&R. I admittedly tried one of those temp roots, so I did another hard reset to flush out anything bad.
Day 3: Just got through using Google Reader. Put phone in belt holder. A few minutes later, I felt a vibration. Pulled phone out and noticed it was rebooting. Put it back in holder. 10 minutes later, I get a phone call. Drag the X to the loop to send the call to voicemail. Then enter my 4 digit PIN to sign in (required per corporate ActiveSync policy), and all I see is the white screen with HTC for a few minutes. Phone finally shows main screen, but acts sluggishly. I didn't try to do anything, just let it sit there. Within a couple of minutes, phone spontaneously reboots again. Ugh. Let it reboot, seems to come up more quickly this time, but I didn't touch anything. Within a couple of minutes, phone spontaneously reboots again (third time!). And there's even more! 30 minutes later, the phone powered itself down, even though it was sitting in my belt holder and is protected by a PIN. I was able to revive it by powering it back on.
Day 4: While I was typing someone's name into the box at the top of my People screen, it locked up but the 4 buttons stayed lit. Had to R&R the battery to get it to respond.
At no time has my battery been particularly low. Right now it's at about 40%, and that's the lowest it's been since I got it.
Do I really have 2 bad phones in a row? Or is something wrong with the EVO 3D?

By the way, I think that every time the phone locked up or rebooted, the top half of the phone was pretty warm. Not sure if this is because of CPU or radio use or both. The battery wasn't nearly as warm but wasn't exactly cold, either.
As a diagnostic step, I've pared down my applications to a minimum. I'll see if that does anything.
It's either configuration (like maybe a bad app or app combo as you suspect) or just bad luck on the replacement. Many aren't having this problem so it's not a design problem.
Ive had my 3D since Friday and I've had several issues.
Random reboots.
Freezing and having to pull the battery.
In the task manager I have 803 MB of memory anywhere from 500-600 mb is in use all the time with nothing running when it gets close to 800 it freezes and shuts off... Is there any way to increase it from 803??
If I switch around to quick from stuff it freezes and I have to pull my battery.
all of my stuff is up to date by the way.

I'd start with a hard reset and not installing a bunch of stuff for a few days and see how it does. Chances are it's an app or combination of apps you installed that's causing it. If it still locks up take it back asap and swap it for another one while you still can. Mine hasn't locked up once since I got it on launch day...

yep - this worked on the EVO 4G, and works on the EVO 3D too. I'm told (by HTC) that this happens because the phone is not able to read the icon image files from the microSD card (for the apps that were pushed to microSD) before SENSE loads up completely - and for some reason, they do not reload the icons after that (unless you either kill the sense related task, or change the scene - that forces reload)

Again, I'm on my 2nd EVO 3D but still getting lockups and random reboots. At this point, it's unlikely I have a hardware problem.
What may differentiate me from everyone else is I use ActiveSync to synchronize my email, contacts, and calendar with a corporate Exchange server.
The EVO 3D's ActiveSync program, which I assume is native to Android, makes me agree to some security policies specified by our Exchange admins. They are:
Erase all data Perform a factory reset, which deletes all of your data without any confirmation. (Note: this only happens after 8 consecutive bad PIN attempts.)
Set password rules Restrict the types of passwords that you are allowed to use.
Monitor screen-unlock attempts Monitor failed attempts to log into your device.
Lock the screen Control when your device locks, requiring that you re-enter your password
Device function limitation Restrict some functions on device like Wifi, Bluetooth, Camera etc.
Does anyone else connect to Exchange and/or do you have nonstandard security settings like what I had to accept?
I just did another factory reset (where you hold the volume down button while booting and use that ROM menu), and I am trying this all over without using ActiveSync. I'm just going to IMAP over my corporate mail. That way, I can avoid these security policies.
I had it reboot on me once...I can't remember exactly what I was doing either. I never had my EVO 4G reboot on me until I started installing different ROMs/kernals and overclocking it.
__________________ "The only easy day was yesterday! Hooyah!"
My phone randomly rebooted last night, I had just went to the music player to listen to a song and the phone decided to shut down and reboot. Afterwards, everything came back fine.
I suspect my phone has done this once or twice before.
Interesting. Mine is working great.
If i had a device that was locking up and rebooting. I would perform a hard reset.
Check if any updates are available. Then start to add my apps. Dont do a restore. Simply install the apps from the market place and set them up from scratch.
If its still freezing, power cycling or what ever go to a store. Might be a hardware issue.
The power on PIN was all numbers, and I do see that one post where someone claimed that switching to alphanumeric fixed it.
Still, these problems seemed like constant reboots? I'd have 0-5 reboots or lockups a day. Still annoying, but much lower frequency.
Not saying that I know that was the answer, just that I remembered that about ActiveSync from last year in the Evo forum (or... someplace around here...).
During the first week I had my 3VO, it was rebooting frequently. I tried deleting different apps but still rebooting. I even did a factory reset and still kept rebooting after that. I finally went back to the Sprint store and replaced the phone. Its been 5 days since replacing phone and it has not once rebooted itself.
This is the EXACT problem my phone is having. The four bottom buttons light up, but the screen is black. Only solution seems to be a battery pull, which I've done several times since getting the phone on Friday.
Yes, it's loaded with apps, but it's interesting that you're having the reboots even after a hard reset.
Same here, phone keeps randomly rebooting and on numberous occassions phone would lock up with screen not turning on with four bottom buttons lit. I am hoping this is a software related issue which an update can fix. And these problems continued after i called sprint the first week of owning it and they reset my data, had me do all system updates, battery out/in reboot, etc. It seemed to have fixed the freezing issue i had playing spiderman 3D(phone would randomly freeze while playing) But the locking up of phone and random reboots still continues.
ok so i just got my evo3d friday night, it is now sunday night. since 8pm last night my phone has been rebooting every 3 or 4 min. i have tried everything, battery pull, switch different settings, remove some apps, updates, i even did a factory reset and wiped EVERYTHING and with no apps or anything installed still it is rebooting every 5 min or so. i cant respond to txt in time before it shuts off, i cant make calls or even check voice mail. im very unhappy with this upgrade, i should have kept my evo4g. i have read several different websites and forums and still can not solve this issue. im gonna take my phone in tomorrow and see if they can swap it out
Its a real shame hearing ur situation especially since u came from the original evo which I'm assuming u didn't have that problem before. You did enough next step exchange for a new one n hope that will fix that issue.
I'm curious for those experiencing these random reboots, can you tell us is there anything you turn on to trigger it ie: wifi, 4g. I remember having issues when I had my moto cliq xt
Happy to report that I had my first random reboot two days ago, after 3 weeks of owning the phone. I am guessing it had to do with some apps messing up. I took the phone out of my pocket and it locked up and performed a quick reboot.
I am disappointed to report that losing ActiveSync has reduced but not eliminated my random reboots, lockups, or power offs. I had several days of trouble free use until I went on a 4 day trip, which went through some areas with marginal signal. Several times, the phone acted up, even one when I click on Maps from my applications menu.
The ONLY commonality among all these lockups, reboots, or power offs is that the top half of the phone's back is warm. Otherwise, I cannot identify any commonalities.
It's as if the phone acts goofy when it's having to fight to get a signal?
Sprint continues their EVO line of Android Phones with what is certainly a first for them - a 3D phone. The HTC EVO 3D boasts 3D technology on a beautiful 4.3-inch screen and get this: you don't even need glasses to enjoy the 3D experience!
