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.

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..

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　？

[Q] Gps gone south

On caulkins rom. Everything was fine, then in the last few days, Gps takes 30 seconds or more to lock. Sometimes not lock at all.
My phone did have a couple of minor drops, but nothing bad.
Any ideas?

Typical for a Samsung phone, you can download GPS status from the market and reset your GPS, sometimes that helps.

im running a stock one that i just got rom saturday and I have been seeing intermittent issues too... sometimes no lock on my 60 mile drive to work!!!!!
im gonna try gps status....

I just came back from a 9 hour road trip, clear skies, my phone would frequently loose the signal altogether or be off by a few hundred feet. Next time I'll just use my Garmin, or an HTC phone.

sniff.. sniff. i loved mine.. but broke it.. as seen in sig.. but iguidance was dead on and only lost signal when i was going through a tunel.... looooong tunel...

It was also working for the initial set up and stopped yesterday for some reason. Oh well. i know where I am going for now.

Clearing the GPS cache with GPS status always works for me. But I really rarely have to do it, and have had GPS on for 8 hours before without issue. Seems like what someone said before is true: not all Samsung's are created equal.

Im inclined to believe this, the other sgs2 in the family didn't loose the GPS signal like mine did during the trip.

I'm still stock and I recently went on a 12 hour drive with a lock the entire way even through the occasional storm... Nothing major.

Now after Clearing it, do you lead GPS Status to Download the AGPS Data after? or After Clearing the GPS Cache, do you close GPS Status, then use Google Map?
I'd like to know
Thank you!

Strange, I've been using this phone for over a month now, and have never had a GPS issue. I use GPS quite often with google maps, google nav, or Waze, and the lock is almost instant. Hasn't ever lost GPS lock either. I'm on a stock rooted EL29 ROM, with EL29 modem and Rogue 1.4.0 Kernel/Recovery. Will not be going anywhere near the touch recovery mess. I'm in NYC, so often the tall buildings will interfere with the signal at ground level, but it's no more than a block off in those areas. But that's a common problem with GPS, and my old Evo had the same issues.

sorry i missed this... no i launched it... cleared it.. and closed out of it.. and let my phone sit in the car for a while...

just got of the phone with sprint after 2 hours of troubleshooting. they made be restart me phone a million times din't work, they made me reactivate the phone didn't work, finally got transfered to someone with a bit of knowledge and its been working so far.
what they did with me on the was:
1. go to settings
2. system updates
3. update profile
4. restart
it hasn't gone to **** yet hope this works for the long run not for now.

Strange thing for me is that my first phone's gps was broken. They gave me the refurb I have now and it was just great. Locked in a few seconds and stayed locked.
Now for the last couple of weeks, it has just been terrible. doesn't lock for minutes at a time. GPS Test app shows pretty bad reception.
The problem is that it only seems to work, when I finally start driving towards the sprint store, to put in for a replacement.
I also went back to complete stock. el29

Interesting - what would be contained in a profile update that would be useful here though? Does a profile update simply reset your GPS in the same way that GP Test does?

i was on the phone yesterday with sprint for 2 hours and today went back to the same ****. called them again after 45 mins they decided to write an e ticket for the phone and went and got a new one. they are saying it's a bug in the white e4gt. don't now if it's happening to any one with black phones.

[Q] SLOW Wifi speed - Something wrong! [proven] Please help

Hi guys,
I have a 50 mbps internet connection at home and work. However, when i run a speed test in both locations, I'm only getting 1-2 mbps download speeds. When I perform the same test on my other android devices, I get the following:
Nexus 7 - 35+ mbps
Evo 3D - 16+ mbps
How do I go about fixing this? Is it my modem/radios? I'm thinking this might be the case as I updated my modem to MA7 and could have done it wrong, for all I know?
Here are my details:
Android Version: 4.1.2
Baseband: L900VPAMA7
Kernel: 3.0.31-265523 [email protected] #1
Build Number: MacksROM AllStar! MA7
Hardware: L900.09
Can someone please help?

Here's a few suggestions to help you narrow it down.
See if it's signal strength by moving closer to the router.
If you're using the speedtest app, test with 5 different locations to make sure it's not an issue on their side.

I've already confirmed it's not my home or work router. All other devices perform fine on it.
I've also confirmed that it's not the custom ROM i'm using. Other people with the same ROM have no speed problems.
It's also not the Speed test app. I've change to about 10 different servers and they all come back with the same results.
Not only that, but my other android devices perform fine on those same servers. It has to be my wifi antenna. But how do I fix this?

Have you verified the md5 of the rom zip?

I'm in the same boat. It seams likes since I upgraded to ma7 I've had a very weak wifi signal. I have to shut off wifi and use 4g. Ive upgraded to mc2, changed roms nothing has helped. The wife has full bars (stock) right now and I have none. I dont know what else to try. I'm glad someone else is having the same issues.

I had the same problem. My wifi on my Note 2 was and is so slow compared to my S3 and S4 I get 25 down on my S3 and 45+ on the S4 but on the Note 2 its about 10 and less its has to be something with the device it's self I got a replacement and still had the problem son may be the wifi radios just suck

Flash a stock rom and see if your speed are the same. And I mean stock samsung not a custom touchwiz rom.
The radios shouldn't matter.... But after you try a stock samsung rom, try upgrading your radio to mc2.

I've tried multiple kernels and had the same issue with all of them. Stock. Perseaus, now I'm on Ziggy.
Also I'm having an issue with people can't hear me when they call me. But when I call them back everything is fine. Tried turning off noise reduction and it didn't help.
I just about to reflash back to stock and return it to Sprint.

Would the wifi scan interval have something to do with it? Not sure myself but just a suggestion.

My issue is that the Damn WiFi goes crazy anywhere from 1 bar to 2 bars and takes for ever to load a YouTube video that is even in HD. I have a 24Mbps connection and typically on any other device I get 15 to 18Mbps. However on here it says that but Sure isnt acting like that.

Ok I did a factory reset and flashed with mc2_stock with reset. Well surprise its still the same. I compared mine with my wife's stock note 2 and everything is the same. With the phones side by side she had full wi fi and I had a small green dot.
Any ideas before I return the back to sprint?

Sounds like a broken WiFi antenna. I had the same issue with my OG Evo, and an Android TV Stick. The little tape strip that had the thin antenna in it had been torn and caused signal issues. I took the phone to Sprint hand got a new back panel with new antennas all around. Fixed the issue.

Network Status Issue, Please Help!

I'm running the Lab Rats v2.3 rom with Persues alpha36 kernel and MA7 Baseband Modem. A few days ago I started having a strange issue with having full wifi or mobile data 4g signal, but nothing was connecting to the network. Restarting the phone would get connection for a couple of minutes until everything loads and then would end, even though still showing full signal. In Settings-About-Phone Status under Network it showed Unknown instead of Sprint, all other info was correct. I tried updating PLR and Profile, but it didn't work. I then did ##SCRTN# (##72786#), still didn't fix connection problems and Network still read Unknown instead of Sprint.
Had to full wipe and reflash the rom, then connectivity started working but still Network Unknown. Again did tried ##SCRTN# but nothing.
Even though I get wifi and mobile data, problem is when I try to purchase apps through Google Play Market via Bill my Sprint Account, it says cannot verify network or something along those lines.
Again this started a few days ago, and all was good prior. The dev who posted Lab Rats told me that the rom has nothing to do with network connectivity, so I was hoping someone here can help me out with any suggestions or a fix.
Thanks

I think its a problem with rom because I have the same issue .I flash a stock rooted or any other tw rom and everything is fine .let the dev know may be he will be able to fix it
Sent from my SPH-L900 using xda premium

Yea it is a prob with the rom. I flashed a different rom and the Network read Sprint again, then I flashed back to the updated version of Lab Rats and same problem. He told me network issue isnt the roms fault, and to try to flash a different modem, but thats not it either since I tried and it didnt work. I think maybe something, a system apk or something was left out thats why it doesnt read the network... I know he removed VPNDialogs.apk which is why vpn apps like Tunnel Bear or OpenVPN don't work, but I let him know and he will probably include it in his updater for those who need it to download and install. So I will compare other roms with Lab Rats for some sort of system apk that sounds like it has to do with network and install it and see what happens.

synergy rom and perseus kernel
I have a similar issue. I am running the synergy rom and using the perseus kernel. I can get data just fine, but I cn not make or receive voice calls. The calls will go through but no sound will be played. The sound works fine in all other conditions. Doing a factory reset fixes this, but only temporarily.

Im having the same issue as you, i am running whomp rom with the latest perseus kernel, it just began yesterday and i ahve tried everything from restoring to a back up, to ##786#. I am lost... no calls can be heard but the call does go through.

As you can see, the rom isnt necessarily the issue as two other roms report the same things.
Usually prl updates or system updates will fix any network connectivity issue.
The unknown network has nothing to do with anything. Its cosmetic and hasn't effected anything other than to remove Sprint from the dropdown bar.
Its quite possible the reason you guys were told thats not the issue is because its not. We, as all the other people here try to make everything as smooth an workable as possible.

I have the same report of unknown and haven't had any data issues at all and I've been running labrats for several months.. No matter how many roms I flash, I end up back to labrats because it truly does just work and if something does happen to be broke, the devs are on top of it..

What PRL are you guys on? We had TERRIBLE issues that I thought at one point may be the phone but turned out to be a network issue. PRL 2000 has fixed most of that for me.
