Phone won't stay asleep

Hello All:
This is my first post here but just reading around has solved many problems for me already. However, my phone (sprint mogul 8600) has been misbehaving and even a hard reset did not solve this problem.
My problem is that the stupid thing won't stay asleep, ruining my battery life and sanity. Is there a way to set it so that it will only wake on active decisions (incoming text, incoming call) and me pushing the power button? I've cruised option after option but I haven't been able to find anything useful.
It still functions properly when it should wake up, it just seems to wake up every few minutes on my desk and i think i have an incoming something to deal with. In the end I have just stopped paying attention and have missed lots of calls because of it.
My apologies if there is a faq that goes over this already, I looked but could not find.
Thanks in advance

Battery life goes down approximately 50% per 10 hrs because the phone turns on as if someone hit the power button at irregular intervals. Is the phone SUPPOSED to be able to turn on for reasons other than incoming messages or using the power button? Its driving me crazy, I can't even go out for a day because it will run out of battery.

Are you running a custom rom or stock rom? If stock, is the most up to date from your carrier? After you did the hard reset, did you test it before installing any cab files? It's possible one of the apps you are installing may cause this.
If it's the stock rom and you are installing nothing, I would say it's a defective phone.
I know on an old PDA I had years back at midnight every night it would turn on, it would do maintenance on my scheduler and then turn back off, but haven't seen my phone ever do this during normal hours.

It has to be software on that rom or additional installed by you. If you haven't installed any software you might want to try flashing a custom rom and see if that takes care of it.

i have had the same problems with my ppc6800 and blackjack 2, i think it has to do with the changing networks... on my drive home from mass to maine it will do it in about 5 spots anyways consistantly. in my hotel in mass i get crappy reception and itll do it every now and then. this has been an issue with both phones. bugs the hell outta me on my trip home cus itll light up, then i grab it to figure out why and theres nothing... learned to live with it

I performed a hard reset after continued trouble with this. It will come on at least 1 time per hour, and as often as every 5 minutes, with absolutely nothing done to it short of initial calibration/data entry. It will also do this sitting on my desk, not moving or anything.
I suppose I could try a custom rom, but I fear I am opening pandora's box, as I am told these phones are on backorder if i happen to brick mine. Any recommendations for a new ROM to try?

This is normal.

Is this sufficient problem to get it replaced? A hard reset and nothing else and problem persists.

It's a win mobile "feature" since the early WinCE days. Every Palm-size/WinCE/WinMO device I've owned turned itself on from time to time. Now, it's blamed on network changes, mostly going in and out of EVDO coverage. When these were simple PDA's, it was blamed on internal housekeeping. If you corner a MS rep on the issue, they will blame the hardware and outside software vendors. I never believed them. Either get used to it or buy a device other than a WinMo based, it will never ever be fixed!
BTW, I'm in my basement where I get less than an ideal signal and my Mogul has turned on and off 3 times while I was typing this.

I have my phone sitting next to me in the cradle all night long, 2-3 hours before I go to bed I turn out the lights to either view my laptop easier or watch TV, if my phone was turning on I would know it because I would have bright light in my eyes.
So I would say it's not as common as you described in the 2-3 times while composing the email. Mine might turn on at midnight, tho I am usually asleep by then, so I can't say for sure, but the only time it turns on (that I know of) is when I receive a text message or a phone call. Emails don't wake up my phone. And I get 20-30 emails a day.
I am on a 1X only network, no EVDO here yet, so it could be an issue with EVDO, in my phone settings I have an option for Service Tone, that makes a beeping sound when I lose or regain service, might try turning that on and see if it's beeping when the phone is turning on. If so, it's a signal issue.

I have this problem too and hate it. Every time I come out of the subway the phone turns on in my pocket. I cant drive at night with the phone facing up on the dash because it turns on every couple of mins. It's completely annoying, kills the battery and launches tons of programs, every once in a while it makes calls too. I would be very happy to get this "feature" taken off my phone!

WinMo devices turning on all by themselves is the reason there are so many screen lock programs available. If you've got a WM device and plan to carry it in a confined pocket (like your pants) check out S2U2 or throttlelock. Your phone turns on when leaving the subway because it's aquiring a signal, it probably turned on while in the train while searching for signal too. While driving, you're probably passing in and out of 3G coverage which will also turn the device on. If you stay in a solid signal area, the phone will stay off for the most part, but that does negate the whole mobile thing a bit. The center of my basement where my home theater is gets a inconsistant 3G signal. My Mogul will turn on and off and kill the battery in a few hours. My wifes Palm, my friends BB's and iphones won't turn on once. Once again, the issue of WM/PocketPC/WinCE turning on for no apparent reason has been a c ommon complaint for years, at least to the Casio E105 days when I started on my WM journey. Since MS has never addressed the issue, I doubt they ever will.

I have never had the phone random come on from sleep. Leaving and entering coverage doesn't change that. I say you have something in the rom causing the problem or a program running in the background

You've never taken the phone out of a pocket or holster to find it already on? My 6700 on VZW did and I think I ran every ROM developed for it at one time or another, each of my 3 Moguls running various OEM and custom ROM's did/does. I've heard similar complaints from coworkers running various
WM devices. A friend I take the train with daily complained about this with his AT&T Tilt too. Both my non phone Axims (x5 & x51) occasionally turned on as did my Toshiba E805, Casio e100, e105 and e115. Every WinCE based device forum I have participated in over the years has featured complaints about WM turning on with no user interaction. Obviously, it's not a deal breaker for me, but it does happen...a lot. The issue in my basement is the extreme of the problem, move the phone towards the exterior walls and the phone reverts to only turning on and quickly off occasionally. Another example. When traveling by LIRR to Penn Station the phone will stay off even when entering the river tunnel ad traveling under Manhattan. At some point when I exit the station, the phone turns itself on. Since I'm walking in rush hour crowds, I've never tried to find at which exact point my Mogul turns on, but it's always on when I get my coffee in Borders Cafe.

I have never taken it out of my pocket and have it been turned on. It is always in sleep mode.

This also happens to me, i own a mogul, and this is really and extremely annoying.
i have test it for few months and this is my conclusion.
As you guys said already just wait for few min and it will turn on the screen, but also when i shake it and when you hit it.
it really is a battery killer.

If it's turning on when you shake it, you probably have a hardware issue.

"No service"

Several times recently (I'm not sure whether it started after I installed the OTA update or if it happened once before then) I have noticed that my phone says "No service" and doesn't pick up T-Mobile again until I power cycle.
It's not that unusual for me to see 0 bars of signal strength in my house; there are dropouts at various places, and I saw the same thing with AT&T on previous phones, so it's not a T-Mobile or Nexus One issue. The problem is that, once every few days, I will pull out my phone and see 0 bars and "No service" instead of "T-Mobile," and nothing short of a power cycle reestablishes the connection. I've tried going into and out of Airplane mode, with no effect, and I also tried using Settings -> Wireless & networks -> Mobile networks -> Network operators, and it never found any.
Maybe related is that when I try to power cycle after this occurs I have trouble doing so -- a few seconds into the shutdown sequence the circling arrow stops moving, I get some sort of notification "ping" and the trackball lights up, and the phone just sits there for a long time. Eventually it reboots -- whether because whatever it's waiting for times out and it continues the shutdown sequence or whether it's responding to my frustrated poking at various buttons while it's sitting there apparently doing nothing, I don't know.
If it's a hardware issue, it's very intermittent; I always have service after the reboot, and as I said, this only happens once every few days. I'm inclined to think it's a software or configuration problem (I'm using the stock 2.1-update1 firmware). Any thoughts or suggestions? TIA.

It happened again this evening when I had some more time to play around with it, so I have a bit more information about this problem.
When I tried Settings -> Wireless & networks -> Mobile networks -> Network operators, the circular arrow spun for a minute or two and eventually a little pop-up appeared saying, "Error searching for networks" or something like that.
It occurred to me that the SIM card might be bad or have a bad connection, so I installed an app (using wifi -- which, BTW, I had on throughout this whole process) that allows you to copy your contacts onto the SIM card and ran it. That seems not to be the problem, though, since that app could access the SIM card just fine, while I still had no service.
I toggled Airplane mode on and off, but there was still no change. I then again searched for network operators; the circular arrow appeared and stopped, then a couple of seconds later the phone spontaneously rebooted and I have service again.
Anybody have any guesses as to what these symptoms might indicate?

Every so often i got service but I cna't send text messges unless I power cycle. If I try to airplane mode cycle it won't let me get out of the mode.

wow, a bit refreshing knowing that I'm not the only one with this issue.
I'm on T-mobile and within the last week I've had 2 occassions where I looked at my phone and noticed no service, a power cycle caused it to freeze on "powering off" screen and I would have to pull the battery. After it booted it I had full bars again.
Within the last 2 weeks I have had issues where I would not be able to send a text messages until i power cycled.
The last time I had no service was 4 hours ago. I had to pull the battery to power cycle and get service again.

Thanks for the reply. I, also, pulled the battery the first time it hung in the shutdown sequence, but as I said in my first message, since then I have managed to complete the power-down after the hang, either because whatever it was waiting for eventually timed out or because something I did (e.g., holding down the power button for several seconds) overrode the wait. Next time it happens I'll try just waiting to see if it will complete the shutdown on its own.
Just out of curiosity, did you have wifi enabled at the time this happened? Bluetooth? I'm not sure whether it's relevant, but I leave both on all the time.
As for the text message problem, I don't send a lot of texts, so I probably wouldn't have noticed if I were having that problem and can't comment on any correlation.

Oh, and a couple more questions: do you have NetCounter installed? And are you in a location where you sometimes or frequently get 0 bars of signal strength?

I have had similar issues with other phones...
For me it turned out to be an issue with my sim card.

I usually have both bluetooth and Wifi enabled all the time...
Dont have netcounter installed.
Dunno about the SIM card issue, unless its a combo of the N1 and my SIM card, because I swap to using my BB 8900 once in a while and I never have text message or no service issues.

Im experiencing the same problem, I have dropped calls in some spots around town (when changing towers it seems), I drop service when inside my home and cant send texts (until a power cycle), horrible 3G speeds of less than 1MB/S all around town (driving and standing directly under the Tmobile Tower that across the street from the tmobile store).
NONE of this happened with my G1....my 3G speeds always sucked though but were usually around 1.5-2.1MB/S.
Im located in Fredericksburg,VA.
(MY PHONE IS NOT ROOTED AND IS RUNNING THE OTA UPDATE1)

Im pretty sure it was the radio update, cause after i get out of a place where i get no signal at all, and i get to a open place I have to reboot the phone to get signal again

I've been busy for the last six weeks or so and haven't been following N1 news around the net. Has anyone heard of any progress on this issue? It seemed to go away on my phone for a couple of weeks, but it's back with a vengeance: it's happened to me about once a day for the last few days, which is more frequently than any time since I've had the phone, so I'd really like to get this fixed somehow.

Can you take a youtube video of it? the more the better to get Google to fix it.
Also these issues seem to be related over here too http://www.google.com/support/forum/p/android/thread?fid=1cc152dbb797df2f000483d7c88e343e&hl=en

Thanks for the link. It seems to me that several different problems are collected together there; mine is specifically the one where I go to zero bars (which happens fairly often; I have several dead spots in my house) and it never comes back.
A video of this would be pretty boring to watch; there's really nothing to see. The signal strength shows zero bars with an "x" and the home screen shows "no service." Trying to power off, or going into and out of airplane mode, shows the spinning arrow for a few seconds, then it stops; a few seconds later the screen goes blank; then a half-minute after that the multicolored "X" appears and the phone reboots itself.

No SMS Gateway
I think this is a separate issue for the phone not switching back to a connected state with the service provider. In the case of SMS, I have also noticed that you may have signal but you have no SMS gateway. No idea where it goes or why it does that.
For whatever reason you loose the SMS gateway phone number settings and become unable to send text messages without a reboot. This is evident by visiting:
Phone
dial *#*#4636#*#* (if you happen to mis-dial this start over after clearing the display or it won't work)
Phone information
Under SMSC: press Refresh.
If no number displays (in my case +12063130004) then you have no route for the SMS messages to take. Entering that number and pressing update will fix it but just restart so it can pick it back up from the SIM/Carrier configutation.

I have this issue sometime in a supermarket here, if I'm in it shopping for a while I loose all signal and have to reboot, also happened with my MyTouch jut didn't have to reboot the phone, but if I'm in there for a quick purchase, it works OK

@wmm, I'm seeing exactly the same issue (zero bars + reboots) and found another guy on the cyanogenmod forum with that problem. Maybe you can add your last_kmsg to this thread, even though you're on stock. http://forum.cyanogenmod.com/index.php?/topic/1599-loss-of-signal-no-reacquisition-issue/

Yep, that certainly sounds identical to my experience. Next time I have the problem I'll force a crash by toggling airplane mode instead of trying to power off (it seemed from the thread that last_kmsg would not be saved if there is a normal reboot, and indeed I have no last_kmsg from the reboot that resulted from trying to power cycle after the last time I had the problem).
Thanks for the cross-reference.

That would be nice, but I haven't seen any activity on the issue on the Android developers' board. Speaking as a programmer, these intermittent, once-every-few-days kinds of problems are a real pain to debug, so I can't blame people for not wanting to tackle the issue...

I had this issue but fixed it by installing the Radio Rom and OS again from the last update. Has not done it again. Now its a power button issue lol.

Epic 4g: DI07 GPS is fast and fixed!!

i get 11 satellite indoor and map is locking very fast and i am not using wifi network

Indeed, I am getting 10 sats indoors with wifi network turned off. Does a cold lock in seconds.

edit: GPS is not fixed. Can't get a lock after trying again this morning. Had to restart phone.

im excited to get this update!! thanks for the post!
in Baltimore, MD area here, no update for me yet!

Just apply the update yourself. No point waiting for OTA.
http://forum.xda-developers.com/showthread.php?t=785028

GPS is indeed very accurate now!
Locked within about 10 seconds, got IN MY HOUSE, within about 10 feet from where I'm sitting.

This wasn't listed as one of the fixes for the OTA. Are you SURE it's actually working better now and it's not just a placebo effect?

ANY reset for an update is going to flush the GPS-xtra assistance data cache and force new downland of Alamanc and Ephemris. There is NO way you would know if this update did anything yet. I doubt ANY GPS changes are in this update since device team is still testing various fixes.

I am really curious too.. I looked on the sprints facebook page and some people said they still having probems with the gps even after the update.
I am still waiting to get the update.. patiently grrrr .. lol

I can confirm this too.. I watched the signal lock within no more than like 30-45 sec. As we all know before it was either nothing or a trickle. I have also noticed the performance enhancements they stated. The signal as you drive and the switch of of views as you drive are faster and more detailed before the directions are needed..
The map caches well on 3G and well on 4G. It makes me wonder, Samsung is using everything as guinea pigs to test so next year they bomb us with the Galaxy S2 which they so happily confirmed along with the Tegra 2 Galaxy Tab 2.
Sucks tho, bastards stripped 4G and Voice in the US.. :-( Oh well still have Motorola N HTC for their toys...
Sent From The Moon...

Placebo effect or not, testing it the same way today as I did yesterday (and multiple days before) and having it work immediately without using wireless networks is awesome.
I'll take it.
One thing to note: When I rebooted my phone after the update, I immediately turned on Airplane mode (habit to kill that time without service bug) and a message popped up "Turn off Flight Mode to update firmware" so I immediately turned it back off. Maybe the update causes Sprint to have firmware updates pushed to the phone that affects this?
Or maybe not. Dunno; I ain't a phone guy.

Apparently you guys didnt read Aero1's post. The GPS apparently always works once after a reset, which the update forced. We shouldn't be able to confirm that the GPS is working for a little while yet.

Nope, fail. Update pushed last night, GPS sucks in the morning. Utter, complete fail. Tried to access GPS with WiFi on, now it's sitting there like an idiot until the screen times out. Had to force ephemeris clear to get it to work again. Also, "accuracy" hard-coded value still exists. And now, screen brightness is, for whatever reason, dimmer under auto than before.

Although I never had a GPS problem it does seem a bit faster now. I was really worried about GPS issues after reading all of the reviews and articles. I use GPS a lot and was very disappointed by what I was reading. I got my Epic at 8am on the day of launch and fired up GPS to test and it worked great. Has worked every day since with no issues at all. I don't understand how or why it works for some (because I have seen other people say the same thing about GPS) and not for others.

I read it. I have no idea who he is. Doesn't mean he's wrong or right, just means my initial anecdotal evidence is positive. Tomorrow may be different, but I don't take things at the word of people I don't know. If it's bad tomorrow, I'll come back and say so. My experience isn't proof of anything outside of my experience.
Oh, did you know the common dog is actually part of the family felinus and not caninus as previously thought?

No disrespect or flamebait intended whatsoever, but isn't that somewhat the point of the forums?

I fear that premature threads like this are counterproductive. If Samsung checks these boards at all they'll think, "Well if even the tech savvy are fooled into thinking it's fixed, we definitely don't actually have to do anything." They are just *looking* for a reason to not actually fix this problem. There really needs to be constant and unrelenting/vocal frustration to force them into addressing this. The minute it appears on gizmodo/engadget is the moment when Samsung *might* begin to care.
I'm particularly fearful that only the gsm versions are getting the official fix because of the Sprint statement that the problem was fixed prior to release. And Epic owners will just be left high and dry.

Yeah, I tested this morning and my GPS is definitely broken, so the problem is indeed not fixed.

Applied update. After letting the GPS search around for a minute it locked outdoors. Turned it off, back on then it locked in seconds. Turned it off, walked inside house turned GPS back on, locked in a few seconds. Walked around my entire house, upstairs and down stairs and it stayed locked to an average of 5 sats. Rebooted my phone, and still near instant lock indoors. This was done with wifi on and then off and with `Use Wireless Networks' disabled for all tests.

Wait a few hours and try again. It'll probably be broken.

LTE Tab Takes Forever To Get Service

When I start up my Tab it takes an extremely long time (sometimes seems like up to 20 minute) before I get service. I'm not in a 4G area, so it's just getting 3G. Does this happen to anyone else? Seems a bit odd for it to do this every time. I'm about to wipe the whole thing and start over unless this is normal (which i hope it's not).

My takes anywhere from 12 to 20 seconds after once it's rebooted.

WTH?!...Roughly 20-mins just to get 3G service?!? Dunno what to tell you there besides that blows! Perhaps take it back to where you got it & request another one and/or see if their demo unit replicates the same issue?

Yup, mine takes around 20 - 25 secs as well to get 4G once rebooted.

had the same problem when first got it. Mine wouldnt even get a connection, called verizon 1 guy i talked to made me turn off device and reinsert sim card worked for about 10 minutes then lost connection again. Called back and another guy told me to do a hard reset (think its pretty lame i have to do a hard reset with the first 2 hours of having device, maybe grounds for replacing dont know) but once i did that i get connection but very weak, sometimes nothing. I have the 4g version as well. Maybe someone can ellaborate more on the issue.

That doesn't sound right at all. Have you noticed that it's weaker and/or stronger in certain areas or is it always weak?

It doesnt really matter but most of the time its at my house which is worse. I have a droid x2. never goes out of service. Im thinking it just has something to do internally with this contraption.

[Q] SGS4 Problem

OK, Firstly let me apologise for the length of this post.
Since mid July 2014 I have been having problems with my phone, at first it kept overheating to a point where it just wasn't comfortable in my pocket and only a reboot would calm/cool things down. This was annoying but I could deal with it. I read somewhere that this could be a battery issue so I bought a new battery. This solved it for like a day but then the problem came back.
In September the overheating stopped but has now been replaced with random switch off and signal loss.
So I decided to factory reset/flash stock firmware (or at least as stock as I can get it as I can't find 4.4.2 that hasn't been molested by 3UK) thinking that as this would take the phone to permanent safe mode effectively, but the random power offs continue. The signal loss has been corrected by only connecting to WCDMA only instead of giving the phone a choice, it still cuts out now and again but it isn't nearly as bad as before. The random power problem can be anytime, I can be just on chrome and *poof* gone, in the middle of a YT video and *poof* gone, this can also happen if the phone is on charge.
What strikes me as odd is this, sometimes I leave my videos that I have stored on SD playing all night and not once have I woken up to a black screen, and this is while on charge. The two batteries aren't part of the "bad batch" of batteries as they both have serial numbers that begin with LC.
Any Ideas short of going back to Samsung? As I can't remember where I put my proof of purchase.
Any help would be appreciated. Thanks you guys.

This was annoying but I could deal with it. I read somewhere that this could be a battery issue so I bought a new battery. This solved it for like a day but then the problem came back.
In September the overheating stopped but has now been replaced with random switch off and signal loss.
So I decided to factory reset/flash stock firmware (or at least as stock as I can get it as I can't find 4.4.2 that hasn't been molested by 3UK) thinking that as this would take the phone to permanent safe mode effectively, but the random power offs continue. The signal loss has been corrected by only connecting to WCDMA only instead of giving the phone a choice, it still cuts out now and again but it isn't nearly as bad as before. The random power problem can be anytime, I can be just on chrome and *poof* gone, in the middle of a YT video and *poof* gone, this can also happen if the phone is on charge.
What strikes me as odd is this, sometimes I leave my videos that I have stored on SD playing all night and not once have I woken up to a black screen, and this is while on charge. The two batteries aren't part of the "bad batch" of batteries as they both have serial numbers that begin with LC.
Any Ideas short of going back to Samsung? As I can't remember where I put my proof of purchase.
Any help would be appreciated. Thanks you guys.

Hi mate,
First thing you have to do is find out who is the culprit , who is keeping your phone awake and running all the time , use an app like:

Let it run for a few hours and check the logs...then we can start to figure out what is going on
