How to know why my phone reboots ?

Hello,
My Defy is rebooting randomly, and I'm looking for a way to know why it reboots.
I'd like to have something monitoring the reboot events, in order to tell me why it reboots exactly, which service or application is causing the reboot.
Is it possible ?
thanks.

mine reboots randomly too, but even worse is that sometimes I get "only emergency calls" and keeps that way until I turn fly mode on&off. It's very annoying because i need to keep an eye on it.
I hadn't flashed mine, maybe these issues get solve if i use another ROM?

No rom solves it. Its to do with signnal strength and 3G. You will find two more threads in same section. But no one wants to help.

Try another SIM card? I read that some SIM Defy give problems and restarts ...

i've only tried a SIM but it's new.
It seems to be a software problem, because it happens randomly and recovers signal every time i switch flight mode on and off...

It has to do with signal strength and 3G. I would suggest that is there is one particular area it does it in, note that area and contact TMobile. They have solved my issues every time I have called into them about it. I suspect part of the issue has to do with the tower.

Have read other threads on this saying same. In the US, T-Mo seems pretty good at responding to these calls.

I'm in France, so T-Mobile should provide me with no help.
However, I will give a try with a new SIM card.

The problem is when you walk into elevator or some cabin. No signal initiates reboot then and tmob cant help in such cases. Is there a developer who can help me with fine tuning one already existing app?. Its called Shutupbattery saver. It switches Off data when signal is low but it needs more modification to make it work. I am ready to pay if someone can help. This tool will also be useful to everyone to save a lot of battery in low signal areas.

Are you running wifi at the same time? I've noticed this exaggerates the problem even more. The other thing I noticed is if you phone is overclocked, put it back to stock and see if it still happens. That was one of the observations I made with both of mine.

With or without WiFi makes no difference. The phone is using official "Orange FR" 2.51.1 ROM, no root, no overclock (even no app), and it may work perfectly for several days and then start to reboot.
It rebooted during the week end. On monday I managed to stop it after several factory reset and wipe of cache. It worked on monday afternoon and tuesday ; and on wednesday morning, during the breakfast the phone restarted one time. Afterward, in the morning several reboots occured, I tried to factory reset the phone two times. The first one with no success (using the bootloader's recovery), the second one by using the "confidentiality" menu of the phone, and it stopped the reboots.
The phone have been working since 10 am and the last reset, and no reboot occured. I installed no app after this reset, I only replaced the SIM by a new one this evening.
I will try the phone like this tomorrow, and on friday I will start to reinstall my applications, and test each one prior to install the next one.

All those observations I made was with stock rom and with no/less apps. I will wait for the Scratman to come back and report his findings. Hope the sim thing works. I am damn fed up of walking into no signal zone again.

If you know the phone is going to reboot, before it does hit *#*#4636#*#* on the dial pad and let us know what the phone is connected to, signal strength, etc. I know I could alwasy tell when mine was going to do it as the phone got real sluggish and it acted almost like a kernel panic. It was a very obvious behavior.

Signal strength with 3G below 102dbm is when it reboots.

OK i came across this wonderful app called Tasker. I tried doing some stuff but this app is realllllllly complex. Can any bright mind download the app here and make a sequence which says "low signal then switch off APN".
I made some but i am pretty sure I am wrong. Here is the code for the direct download. It is a trial and will expire in 9days.

I have the same problem with random reboots.
I sent it in to Motorola and got it back now with only the speaker exchanged (!?!).
Of course now I still have the problem. Upgraded then to Finland 2.2. with Pays Mod, but reboots still sometimes (once or twice a day).
Tried ShutupBatterySaver to turn of data connection when the signal is too low --> still reboots.
I think I can remember that once somebody in this forum posted a link from the Motorola support with a bugfix, but I can't find it anymore. Anyone here knows more?

Has anyone else tried replacing their SIM with a uicc SIM? Others on the non-us Moto forum are reporting SIM replacement as a cure -- but I recommend you get the latest uicc version.

hi
i'v got mine yesterday and i have this prablem too. last night when i was sleep it happend and i woke late for my class...

Data not working on phone despite the rom

Okay, so my problem is that I'm not getting data on my phone suddenly. It doesn't matter what rom I'm using, it starts off with only bars, no data. Then after a while it goes to 1x and stays there no matter what even though I'm in a strong 3G area and have gotten 3G here 24/7 before. Any ideas on what I can do to fix this? My roommate is behind me with his Droid X and he has 3G so it's not on Verizon's end.

Most all of the time when I flash from a clean (Factory Reset) I need to select the data roaming boxes in the mobile network settings.
I know tech support told me something about one of them, but I can't remember which one it was or what it was about.
But I think it has to do with how close I am to Canada?
I know if I don't select at least one of them, I get NO data.
Also sometimes I cycle Airplane mode to "Motivate" 3G.
ENJOY...

I used airplane mode for a second to try and switch it and it just turned all data off again. I gave up and went to sleep, and when I woke up it was 3G again. Not sure what the deal was. Maybe it was verizon. I'm in Williamsport PA so maybe they're gearing up for LTE here. That would be awesome. Thanks for the responses.
EDIT: My cell standby is abnormally high. Wonder if that has anything to do with this..

If all else fails, you could try a esn reset or update to the 722 radio.

Edit- just saw you're in china, so verizon is kinda useless, lol. sorry man...
Swap the ESN by moving your number over to a spare Verizon smartphone, then right back to your old phone. This forces the data stream to switch, and if it got corrupted it will be reset. Please note you MUST do this between two smartphones so you keep your data plan intact.
I believe verizon can do this from customer support if you don't have a spare smartphone, but i haven't tried it.

Thanks i will have a try

Up , anyone have a good idea for us　？

Letitride & artvandelay440 just helped me out with this, call *228 and use option 1, then after its done call back and use option 2, this worked for me, i had no service, but now i'm back on 3G.

The problem now is i am not in US ,so this method don't work for me in China .
Any other methods ?

[Q] GPS issue?

Hey Guys. Has anyone had the GPS problem on stock setup or after root and flash? I have to reboot every time in order for it to pick up the satellites. i have been using a gps check program from the market to check the status. It will only see 1 sat when the phone has been running for awhile, it won't connect at all outside with clear skys. I read some people having the issue on the sprint site but, not much about it here. Anyone?!?

Did you try Sprint Navigation? That normally gets a gps log on right away. Google isn't working proper on any phone i used. Gladfully we on sprint have free Sprint navigation from telenav whatever beats Google nav anyway. Try it you probably get a log on to gps right away.

Download GPS Test from the android market. Then go into setting and clear the agps and it should lock in within seconds. That's what I did. I only had to do it once and my gps has been fine after that. It locks in within 10 seconds.

I had the same exact issue
To be specific I had my phone bearly 2 weeks, One day while just sitting on the counter with the screen off in what should have been idle state my phone was so hot I could bearly pick the thing up the digitizer or non of the buttons on the screen would function and it was super slow.
I had to pull the battery out to reset the phone the battery history showed it drained a near 90% + charge in under 2hrs.. to say the least I had a couple LOS after reboot everything was FOTB.
Since then my GPS worked for crap it was inermident it seemed the cooler the phone the better it did work but after a certain warm temp it would fail and anywhere around warm or less it would work intermidently at best..
Long story short after talking to someone for several houres he decided it haves a hardware issue after going to a sprint store and pulling teeth they finaly order me a replacement..
After investigating here is what I personaly found out.. The GPS is intergrated into the cpu, i dont know if it is on the T-mobile version with the snapdragon DC CPU, but what I think actually happined is my CPU overheated to the point of desoldering or lifting the chip or causing the internal GPS portion of the CPU to fail or degrade. I am asuming maybe a LOS crashed my phone to the point of causing this failure as of now I have a new phone and it did resolve the issue.
I had the most difficulty with trying to prove to the store that the GPS was bad because the store employees would try and argue that A-Tower triangulation acurate to 3000meters is good enough then after training sprint employees and technicians the difference between A-Tower & GPS I was finally able to get a replacement phone.

I've had this issue happen to me twice on the stock ROM. Google navigation could not get gps lock for several minutes in clear view of the sky. I rebooted the phone, and navigation then got an almost instant lock after going back in. I don't have another gps monitoring app, so I don't know if my phone was having an issue, or nav. I periodically had similar issues on my Droid 1, so it may not be unique to this phone.

Well like discussed in a other tread sprint navigation has no issues to log on to gps. Google nav has issues. It is almost with all Android phones that Google nav has issues to log on to gps. Sprint nav logs on basically instantly.

Google maps locked up on 10 of 11 sats in less than 5 seconds the first time I tried it this morning. I've seen better accuracy (mine varied between 12-18 ft) SN ratio was great all 10 were over 20). I've had my phone since Saturday and GPS test found and used 5 sats in my basement (first time I've ever seen that) turned on my wife's epic and got the same thing.

This is what I get but I don't know if it's good. I can never get shopkick points. I love show kick.

I've been having this issue more and more lately.
Its the same thing every time, after the phone has been up and running for days on end, the GPS will not work at all.
Reboot and its 100% fine and super fast lock & accuracy.
But its now to the point that I just reboot my phone daily just to avoid running into this.
Doesnt help that I dont even have 3g in phoenix, curious if its part of the problem.

I had a lot of problems. Bottom line is that I think some phones may have borked gps chips. After going to thru tech support online, on the phone , and finally taking the phone in, they replaced it and the new ones works great.

Hey guys, just wanted to share my findings with the GPS problem a lot of people seem to have, including me. I was having issue's connecting my GPS all the time, it would not locate the satellites unless I hard reset the phone until I found this software in the market.
It's called. GPS FIX - just search, GPS FIX - simple enough...right?
I tried using the other GPS program everyone talked about, and clearing the whatever but it never really seemed to work. This program however works FLAWLESS! You start your GPS, launch this program, it finds everything, then you launch your Nav software or whatever and it pops up instantly.
Hope this helps...
*side note - my friend has a HD2 and his has the same issue, and also another phone he uses as well. So the GPS issue seems to be something a lot of phones experience, makes me feel better it's not just isolated to this device.

I'm currently running the Starburst rom and using GPS on the road heading to South Carolina. The gps and navigation has been working perfect and accurately

It was worse on the galaxy s, the culprit was the spring arm that makes contract with the GPS antenna on the back case. The arm would lose tension and it would then loose contract. I had my first issue with GPS this morning, wouldn't lock. Haven't tried it since my drive to work

All I know is I run this software and mine works great. Without it I have to reboot to get it to work.

Just enter ##gpsclrx# into your dialer then enter your msl code. Let it do its thing then reboot your phone. You should have much better GPS locks afterwards

Sorry for the late response. It clears the GPS data on the phone, and forces it to resync. This has in the past on several devices resolved GPS locking issues.

Cool thanks!

Nothing works/GPS/4G

I had issues with my phone not using 4G(speeds were under 30kb). Only way to test out new rom is to drive to an area that has 4g about 2 hours away. I go there about once a month, but to test it out is a pain. To top it off my GPS rarely works. Tried ALL ICS modems.
I gave up and updated through sprint and long story short am now on FI27 rooted. FI27 stock without root caused nothing but problems. Gps wouldnt work, 4g wouldnt work, wifi wouldnt work, gave up and rooted it and flashed agats kernel.
Now my google maps shows my location but does not lock. Gps status app does not pick up ANY satellites either. 4g is unknown as I wont be in 4g area until Thursday.
I'm so lost with this phone, it's problem after problem. It's my 4th android phone and only one to cause so many problems. It's making me flip out.
Any help, of course, appreciated.
Just flashed original FI27 kernel and still no go.
Flashing FI27 Rooted through odin. Testing

Sounds like you need to exchange it with sprint. Its probably hardware defects.

Have you tried using FK09? I've experienced higher 4G and 3G speeds, and I've had faster GPS detection times.

I sort of had the same issue. My gps one day decided not to lock any longer (after working great for awhile even indoors) , i was so frustrated i decided to open the phone up and have a look at the antenna. To my surprise the antenna is on the back cover of the phone. Here are the 3 things i did to make it work.
1.Odin back to el26, flashed FI27 modem drove around a bit to make sure i got a good lock, accuracy at 8 meters or less. Then i nandroid back to Paranoid rom.
2.Cleaned the connectors to the antenna with alcohol.
3.Unplugged the connector, don't know what that connector is for =] - i just wanted a way to reset the hardware.
As you can see there is no antenna to be found, there is a ribbon connector on the bottom right of the image (out of the shot - first picture) i disconnected that thinking that might reset the hardware.

Here is the antenna on the back of the phone when you unscrew it.
I was so fed up, that I just did all the 3 steps without checking the gps checking in between, in the end it worked. I would recommend odin back to el26 first getting a good lock and go from there.

Thanks for the replies. I odined using FI27 stock rom rooted clean install wiping everything. The gps works but I have to use all settings under "Location". Also, it only worked outside of my home and had to drive around for a few seconds to lock in some satellites.
Agats kernel wouldnt do it at all. Stock kernel works(not inside house though), but the location settings sound normal?
I'm tempted to go back to el26, but not sure. Im hoping it is just the new area I moved to (Poconos PA) because as soon as i drive a few seconds I get a lock. Right now back in home I dont even have 1 satellite being picked up.
Going to back to NY Wed/Thursday, how would I know if my 4g is borked or whatever before going out there since I wont have a computer to mess around with it?
Thinking of going to el26 and maybe just leaving it at that.
Not too good on opening phones. Scratched my xperia x10 to crap lol. Could of sold that for 80 bucks at a store but it has constant boot loops. tried a reflow hack on the board but failed

I don't have GPS aiding turned on in location, actually there isn't a setting for that in paranoid rom - but i do remember on ICS i wouldn't turn that on. How accurate is the lock using GPS Test or GPS status?

Its 4:55 am and im at dunkin donuts. Its at 4m accuracy with maps. Gps status reported 4 errors and 8 out of 12 satellites fixed. When i put phone out of window it goes to 9/11 and errors at 2. Inside car the numbers get worse but lock is there. Im hoping its just a ug.
I think ill bring my laptop this week when i go to ny and start flashing all roms and modems lol.
Do the gps numbers seem okay? If thats good then next thing would be to fix 4g. Gotta test gps without network and see if it locks.
Wish me luck lol
Edit, it all works now. Think I'm going to stay with rooted FI27 stock rom. Too many risks trying different roms out.
Thanks everyone.

How absolutely F**KING ANNOYING!!!
Here, in my area, I was told to reset the network every time I had an issue, the problem with that, is that I have to reestablish ALL of my network connections again (WiFi and BT mainly which is a PITA)... so... I used Airplane Mode on and then waited and then off and let it reconnect and this works about 60% of the time.
I want to try this to see if it helps, but holy hell why when you lose it after a reboot? I auto-reboot once a week and manually sometimes when I really can't get Data without restarting.
Painful.

Yes, you have to redo it after a reboot, but it doesn't take long to do, and I haven't tried it, but you might be able to just do the "apply" option since the asterisks are still there after the reboot. This should fix the problem you get for data, so you shouldn't have to reboot for that reason anymore.
ETA: I researched what the Block AP option was and that apparently will prevent you from having to redo this after reboot!

I did this based on a post on Samsung Members previously (you can see that screenshot in my post in the cell reception thread here), but I haven't seen the instructions with the Block AP option in it. What does that do, do you know?
I've seen instructions with both the SA and NSA versions of the 5G selections to choose, too.
ETA: Based on my research, the Block by AP option prevents you from having to redo this after rebooting the phone.

Thanks guys! I just did this and I guess we'll see over the next few days how this works.

Yeah, one day out and I am STILL having connection issues, even after applying these settings. I am going to head to a T-Mobile store later and throw this thing (well, something else) at them and tell them to figure it out.
Nah, the guys at the store are awesome, I'll see what they have to say.

Strange. What are your connection issues? Maybe it is something different than everyone else is having. I hope the store can help you, as I've never been to a T-mobile store and only have been in a Sprint store like three times (before online phone ordering) in the 21 years I've been using their service, so I don't know how much the store people know.

The problem is the mainboard itself, I got replacement from Samsung, which has perfect connection on Android 11, I updated to 12 without any issue. I tried to downgrade the old one back to 11 and the connection issue is still there.

This does not happen all the time, but it happens often enough to where I am worried about work (I am On-Call most of the time and need to be able to get calls).
I am on WiFi when home. Pretty normal.
I leave home and I MIGHT have data/voice
If I do not, I normally put my phone in Airplane Mode and then back out again and things are okay
If I am driving and move to a new tower, there is a 50/50 change I will need to airplane mode again to get voice/data
Resetting network connections (which is what T-Mo told me to do every time) works, but then you have to log back into WiFi and reconnect all your BT devices again, so this is definitely a NO-GO for me.
edit: Here are my settings using the instructions in the OP:

Just curious, but why do folks think this is a hardware issue ? Everyone's hardware failed after update ? I have the issue but following the procedure in the service menu seemed to take care of it for now at least .

This does not happen all the time, but it happens often enough to where I am worried about work (I am On-Call most of the time and need to be able to get calls).
I am on WiFi when home. Pretty normal.

Hmm, that is a strange issue! I haven't had problems when driving around locally or two hours away (prior to this temporary fix, but I've had the issue for a while, not just since 12 came out; I haven't driven far since applying the fix, but don't think I have had an issue with it - I did have an issue with WiFi tethering not connecting to my car stereo one day, but I don't know if that was after the fix or not).
ETA: I checked my Google Maps Timelime and that tethering issue happened before the fix.

We lost internet here at work the other day, turned on tethering on the device, laptop would connect but no internet.

Do you have tethering as part of your cell plan? If not, it might not allow you to use it even if you are willing to pay for it. Tethering works well on this phone for me, although T-mobile removed Bluetooth tethering as an option for some reason, so only WiFi tethering is an option. My plan comes with 60 GB of tethering, so no issues for me.

It's part of our family plan.

So, just an update here.
When I originally made the changes, somehow it reverted and the issue still persisted.
I have the changes applied now and have done a few reboots and the settings have stuck.
I have NOT had the issues I explained above since these settings have "stuck", so take that as you like, but as of now, I have not had connectivity issues and all seems to be working well.

I did those settings yesterday afternoon and made it worse..........wouldn't pick up 5g. Finally did a chat session with T-mobile and finally got 5g again.
I did notice earlier in the week that the device kept dropping calls left and right, not sure what was causing that.

Did T-mobile say anything about fixing these issues?

No.

So 3 weeks in after the update and still experiencing horrible data network issues. I drive a lot and this thing has become pretty much unusable on the road. Tmobile offered me to either receive a refurbished Fold 3 as a replacement or to switch to different phone altogether. As much as I love the Fold 3, I might not have any other choice. Have you guys replaced your Fold 3?

I don't have the money to switch to a different phone even if I wanted to, but I love this phone. I just hope they fix it so it can roam. I have the temporary fix on it and that makes it work, but roaming will be helpful for longer driving distances, especially since I tether my Android car stereo to my phone for Google Maps while driving and other apps while sitting in a parking lot etc.
Does the temporary fix not work for you?
