GPS usage crashes phone.

I applied the OTA update and every time an app tries to use GPS my phone restarts. The GPS icon blinks about 3 times then the phone turns off. I disabled GPS and still have 'find by WiFi' on and Google Maps gets pretty close. I also did a master reset and formatted my SD card. Last ditch effort I updated my PRL and profile. No dice.
Other thoughts: Amazing phone and I want 2.2.

I believe (using the GPS for 2 days with no crash) I was able to fix it by going into the bootloader [power button and volume down] and selecting "clear storage". My guess is that doing a master reset from withing the phone didn't clear everything.

Exchange your phone
I have had the same problem. A week ago monday after Sprint pushed OTA update phone worked even better than when I first purchased. For two days that was, I recieved a gmail, opened through notifications and from that moment on my phone has become a nice musical lit-up papper weight. I had a Hero before and NEVER had a crash or reboot. My Touch Pro was another story. I have done now 3 hard resets. After number two I only installed updates to Sprints bloatware(sprint nav) and google branded apps. Two days later I recieved a google-talk message and uppon opening it, it all started over again. I can reproduce this rebooting by launching any gps software with gps set to on. Sprint nav not only causes reboot but wipes credentials that you enter when you first launch app. I can launch gps programs if the GPS settings are ALL turned off(both switches). Of course I have to log into Sprint Nav again after every crash. I thought this was fixed after my last hard reset, I have not downloaded anything (no root)or installed any apps since my last reset. I just got past my 30 day but I am going to RAISE HELL later today, obvously this is unacceptable in a new phone(flagship), SPRINT and HTC were notified last week. They did take notes but they are going to try to get me to submit a claim rather than exchange. Neither Sprint or HTC seem to know shi* about this rebooting issue. Obvousily nobody checks sprint user forums. I urge anyone with crashing/rebooting to take back for exchange. Do not waste time trying to fix yourself. I fixed myself 3 times only for the random rebooting to come back within 48 hours. No 3rd party apps other than Sprint(I was afraid to download anymore). I won't even talk about the screen splitting from the base of the phone, I doubt they know anything about this issue either. So my state-of-the-art smartphone is now a 4g less, crappy 3g service, non functional gps, musical (splash screen) papperweight. This was the only phone that I have waited very impatient for and this whole experience has left a VERY bad taste in my mouth. They even screwed the launch of this device. Best Buy and Radio Shack were the only ones taking preorders and Sprint screwed the activation and provisioning up the day of launch as well. I wish I could hate this phone, I would terminate service with Sprint after this experience.

im runing OMJ 1.6 which inclues lastest OTA and and last night i opened maps it asked me to turn on gps and when i did i had constant force closes had to take the battery out to make it stop, couldnt do anything because everytime i did force close it reloaded the system but force close again.

I have had this issue since I got my phone June 5, anything that requires the gps shuts down the phone. I have been waiting for a replacement phone from Radioshack for 3 weeks. I have tried resets, updates with no luck. A local Sprint tech looked at it and told me he thought it was a hardware problem with my phone.

UPDATE
This morn I took to a Sprint repair center. After looking at the device she said that there was water damage and that the stickers had turned red. She also said she found the GPS reciever loose and soldered it back. Funny thing is is that me EVO has never been dropped or near water except for the spray that was used for my invisasheild. I was extremely careful about the aplication, in fact I screwed up because the first application wasn't wet enough. Also I have a PRO2 and Hero as well and as you prob know the batteries are interchangeable. As a result I am constantly swapping batteries because my EVO loves to kill batteries pretty quickly. I think I wold have caught the stickers turning. Also with all the problems I know I have looked to see if there was water damage. Of coure she never produced the stickers and they have now been removed. As I right this right now I am waiting for my EVO to reboot again. NOW I HAVE NO SOUND AND HAD TO HARD RESET MY PHONE! Oh and the repair person said I had too many Apps as well. I brought the phone in this morning with its default settings and apps. If there are too many apps than thats your fault not mine. I am soooo pissed about this whole experience, it's got to the point that I am actualy starting to laugh because Sprint seems so incompetent.

This afternoon I was showing my phone to a client and I launched the normal GPS apps, Google maps, Navigation, GPS Status and CarLocator. As soon as I enabled geotagging on my phone crashed/rebooted. To fix it I went to the bootloder and cleared the storage so that everything would go to stock settings. So far I haven't had a crash yet. I can handle not having geotagging as long as everything else works. Though it is a great feature to have .

Now my phone restarts even though geotagging is off. Anyone know of I can reflash my Evo though the HTC rom manager on a computer? I think putting the default rom would narrow it down to hardware or software.

I did hard-reset on Friday morning and installed all of my apps and then some, but did not install wheatherbug elite which worked fine on my Hero and worked fine on EVO for three weeks prior to Sprints OTA. So far so good,wil post results in fuure. No reboots so far and its been over 38 hours. I read on another forum that WB does not release GPS even after uninstall. Will post results in a day or two.If this is the fix by sprint/htc than give me back my phone with no updates!

???????
Ok, right after I posted my last post I recieved a phone call, durring wich the battery died. I replaced battery with a fresh one, powered on, launched sprint nav, and it rebooted. **** so much for the weatherbug idea..... After reboot I launched google maps, again reboot. I have not installed any apps since noon friday. I have played around non stop with ALL the apps and settings and have not changed anything since friday afternoon. Its 1:15 Sunday morning and nothing has changed on my phone for around 36 hours! Is this a software problem or hardware problem? Software problem means I will wait untll sprint fixes their update wich seems to me caused all this or is it a hardware issue that I need to figure some way to replace even though no EVO's can be found?

Spoke to HTC this morn, htc says that this is a known issue affecting some of their customers and that the carrier (Sprint) should have replaced it already. Even though I bought at Radio Shack. Because sprint has acted so unbelievably incompetent HTC is going to send a new unit in 4-5 days. So anyone having GPS problems and did the OTA should have their phone replaced. Those are not my words but HTC's. Also she explained that my first call for help should be HTC not Sprint. She claims she could trouble shoot better than Sprint. Also advised that Sprint tecs are worthless. I could have told her that.

Evo reboot fixed
-------SOLUTION FOUND-----------EVO REBOOT---------------GPS REBOOT-----------
Step one, call Sprint and get your msl code (unlock code).
Step two open the phone dialer and press “##GPSCLRX#
Step three input the code given to you from sprint (phone will reboot in 20 seconds)
Then launch your GPS programs and you will notice they work (at least for moment)
I will keep my codes on hand for the more than likely event that after 24 hours of use it probably will reoccur all over again.
I am on my second EVO now and I have painstaking already gone through all the hard resets and troubleshooting apps. Repair store and service calls to both Sprint and HTC as well. This is the first time I have gotten the phone to work after the GPS reboots without a hard reset.

EVO Bug? GPS + phone call = reboot

I was using Google Nav on a roadtrip last week and I tried making a phone call. Now once the phone downloads all the maps over the data connection (which it already had), there's no reason you can't run GPS and voice at the same time. I do it on my wife's Motorola Droid all the time and never have an issue.
What happened with the EVO was strange. I understand that if voice and data try working at the same time it will cause an error and they won't work, but in this particular case, my phone rebooted itself.
I thought it was a one time thing, so I tried it a bunch more times and found that each time, it rebooted. Sometimes it took a minute, sometimes a few, but it always happened.
I am running stock 1.32.651.6 (not updating/flashing till CM6 comes out) with unrevoked (so I can use wireless tether).
Can anyone else test to see if they encounter the same problem?

I've had VZW Moto Droid and I now have the Sprint EVO and I can talk while the Google navigation is going. I know its still on because the NAV lady blast her voice while I'm talking.

not that you mention it, I remember this happened to me once couple of days ago. I was like WTH? my EVO never rebooted itself, that was the first time
since then I do not think I used the GPS while on a call so I will try it again and see what happens

i have not had this issue.

I've had this issue twice, only two times the phone has ever rebooted on me.
Both times I had pandora (or last.fm) playing in the background, navigation actively running, and then the phone would ring.. within the first 30 seconds of trying to take the call the phone rebooted itself

Yes Evo + GPS + Phone call + Unrevoked = REBOOT !
I have consistently experienced this problem and think UNREVOKED is possibly the culprit. I will attempt to UN-unrevoke my phone and see if GPS + Phonecall = Reboot or if it's only with UNREVOKED installed. I have experienced this reboot on at least 5 occassions while incall and driving.

GPS reboot issues

Hi there,
Now I've come across a few threads that mention reboot issues. However mine seem to be almost unique.
The biggest thread I came across was more along the lines of overheating.
Everything on my phone functions normally. GPRS / 3G, WiFi, Bluetooth (I think, never use it!).
First issue: GPS takes FOREVER to lock. A good ten minutes, at least. Whether I sit and wait for it to lock or just start driving. Makes no difference.
GPS eventually locks. A good 20 minutes (give or take a few minutes) in, and bang. Reboot.
My first thought was the radio. I was running the very latest one (in the radio thread). I downgraded. I tried 4 older radio's. Each previous one improving the stability. However all except the latest only keep the GPS working for around 20 minutes after locking.
This morning I flashed the oldest radio (first post of the radio thread, oldest one there).
Results in my testing on the way home are quite different. After 20ish minutes I didn't get a boot loop. NDrive went crazy, and stopped navigating. I restarted the app and the GPS refused to lock.
I had installed CatLog some time ago. In my early experimenting, I ran the logging while driving. It seemed to have prevented a reboot but instead created circumstances like above where the GPS stopped working mid-navigating.
I'm running Pays DHD Rom. When navigating its running on battery alone. Temps don't go above 35 degrees Celcius. My phone is rooted, s-off'd as well.
Does anyone have any suggestions?
Short of un-rooting, finding a stock like 2.2 ROM and turning S-on and sending it back to the shop I bought it from, I don't know what to do
Thanks.

In my personal experience all GPS receivers loose sensitivity over time. Some go off faster other stay fine for a few years. If it takes that long for your GPS receiver to lock it is most likely caused by lost sensitivity and no ROM will fix this. The very last thing you can try is to download one of the GPS manager apps and perform a full wipe of the GPS data followed by GPS cold start. It should lock within 2 minutes. Otherwise install a stock ROM and apply for warranty repair.

Agreed. Definitely not the rom. I installed cm7 and damn its a great rom but the problem persists.
I downloaded one of those GPS apps. When soft resetting it rebooted my phone sad days.

So I've pretty much given up.
Tomorrow its going back to where I've gotten it from.
After downloading the stock RUU (first Eclair and then Froyo. Lets just say Eclair didn't like my phone at all) and getting it on the phone, I'm finished.
The moment I turn on GPS... instant reboot!
If you ever have troubles like this, don't waste your time, just take it back!

Weird Lag, Sense restart(no FC) then Hot Restart issue - I can reproduce it

Have a VERY weird issue going on. I've been using Burnt Droid 1.4.2 by Netarchy since it came out. I decided to flash his new 4.3.4 CFS-NoHavs,noSBC, with static undervolt (i wanted to try and see if it was stable since I had success using undervolted kernels last year). I used proper procedure and cleared cache/dalvik-cache before flash. I downloaded the new Angry Birds from amazon and started playing it for a few minutes phone started lagging very bad, then had to restart. I said forget this; undervolt is probably causing this, and reverted back to the original 4.3.1-cfs-nohavs-nosbc which I never had a problem with(used proper procedure above to flash back kernel as well).
Now a day later at night, I decide to run my phone down because I'm trying to recalibrate my battery(I'm at less than 10% at this point). So I load up Wifi, turn on Pandora, and browse the internet. Not even 5 minutes into it, here's whats occuring in order:
1) Bad lag.. Pandora starts stuttering, so I hit the home button
2) HTC Sense restarts, It doesn't even force close, or at least it's not telling me
3) a Hot restart occurs a few moments later... (no white boot screen, just starts bootin from ROM screen)
4) At this point, sometimes its still laggy, sometimes it's fine. If it's laggy I must do a battery pull because It will keep looping to this point.
I can rinse and repeat this running pandora + browsing the web, and the same 4 steps above will happen within moments of eachother. I've been using this ROM since January with no major problems like this
A few side notes:
-I have Evo hardware 0002 (launch day evo)
-Rooted with Toast's original root method, eng .76 boot loader
-Newest radio/PRI/NV/Wimax
-My phone does not randomly reboot on me normally. Reboots only occur when following the above steps.
-I do not use Set CPU
Here is where I am very superstitious. I've been closely monitoring the "Boot looping + no Recovery Access" forum, and similar forums to this. Within the past few months I have tried out a few different CM7 nightlies. I have never flashed RC2 but I have flashed some after and before and tried those out for a while. I just hope my phone isn't starting a dying phase in relation to the problems people are having now.
Is there anything else recommended before I end up doing a full wipe and reflash the rom?

I'm not really sure what's causing your problem, and If i was in your situation, I'd most likely do a complete wipe, including calkulin's format all, and either restore a good nandroid, or reflash the rom from scratch.
That said, I don't believe CM to be 'dangerous' to run or anything like that. Yes, it is odd that an increasing number of people are reporting somewhat major issues, with boot looping the splash screen, and being permanently stuck there. However, that doesn't mean CM is the cause. It does seem to be a common denominator in the people that this has happened to, but there are soooo many other variables that come into play with something like this. There is no proof that CM caused it, but it does seem odd that everyone it happened to was running CM. Also, I'm sure there are thousands of CM users, and a select 8-10 people have reported these issues on here. That's a very low percentage, overall. With all that said, I myself won't be running CM in the near future, either until it's confirmed or denied that it has anything to do with these issues. I'll just be playing it safe, just in case.

I'm stock everything, no root or mods and it restarts at the 4g screen skips everything else...

I think I will do the format all and completetly wipe it and reflash the rom from scratch. Thank you!

LT28at w/ JB lt28h .211 major gps bug?

I've been running the only official lt28 JB firmware for over a month now on an LT28at with AT&T as the carrier. Overall pretty happy with it, haven't noticed any 'day 1' bugs accept for the video recording lag (which for whatever reason is phone playback only? on my pc, through vlc, all the video's look great.)
However, only July 22nd, Google released the updated maps app....and things have kind of gone south for literally anything gps related ever since...
The issue is tricky. After i installed the updated maps app, my phone froze on the map screen while searching for a gps signal. After about 5 seconds, the phone rebooted...but it wasn't a full reboot it seemed...it only took another 5 seconds or so before i was back at the lock screen. If i hadn't been physically looking at the phone, i never would've noticed it happened. Before this update; i had never encountered this problem.
After the kind of 'mini' reboot thing...no matter what, any gps related app (my tracks, gps status, Torque Pro, etc.) would do exactly the same thing. If i turned the gps off or never used a gps related app, the phone would function normal as ever...after manually rebooting the phone by either a full reset, or just turning the phone on and off...the gps would function normally again...I could get a lock, could use any of the apps, etc...
after a few hours, though...it would freeze up on gps stuff again, and get into the same boot loop issue with any time the gps sensor was used.
I've tried rolling back maps, but the problem remains...and i'm kind of stuck now...I'm positive this showed up with the newest maps update, as i had been using JB for a while before it and never had any gps problem of any kind...
what i've tried so far:
flashed an AT&T ICS firmware back...gps functioned properly for 2 days without a single problem. because this is an LT28at, pc companion cannot do a repair for this firmware. I get a 'we couldn't find any software for this device' or something of that nature. I've wiped everything through flashtool, and reflashed multiple times, without any form of back up data. I'm not rooted anymore, as i wasn't crazy about the rooting method for JB to begin with. figured i'd just wait for the time being.
tried 2 different .ftf files of the same JB firmware...both have the problem.
clearing cache of any gps related app i have doesn't seem to effect anything.
the only thing that seems consistent is that the problem only starts happening after the phone has been on for a few hours. If it try gps after a fresh boot, it works perfectly. If i try again a few hours later, most of the time it freezes and quickly resets, but keeps doing it non-stop until i shut the phone off.
is anyone having anything like this? Any help would be greatly appreciated...
EDIT: this can be marked as solved i guess...found info on other phones with 4.1.2 having similar problems...something to do with memory allocation and the adreno 220 gpu...rooting and running a memory tweaker/task killer (greenify or autokiller memory optimizer both worked) has been a good enough work around for the time being...hasn't happened once since i switched autokiller to 'aggressive' memory management...no gps problems, and not one redraw...phone is actually running better than new now haha...
