Hello everyone, I've got an interesting problem that I want the experts here at XDA to help me troubleshoot. Feel free to ask questions as I know there's probably a million variables at this point with stuff installed, uninstalled, gps, root, task killers, etc.
alrighty with that said, I did the e-wrecked gps fix (changing the operation mode and server location+port). That seems to work great in terms of time to lock on my position as well as improved accuracy. Over the next couple of days I noticed some really choppy and lengthy phone start ups after the fix.
Eventually it got to (and currently is at) a point where it kept rebooting the phone, or at least touchwiz. It would load up, scan media, search for the network, do all the start up stuff, then lock up, and turn the screen off. Hitting the lock button/power button does nothing while it resets itself. Then it resets to the lock screen, the screen lights up and it goes into "searching" for the tmo network while doing the storage preparations, and other boot up stuff. It does not restart from cold (with the vibrant, tmo, and galaxy animations, only the lock screen and OS boot process)
Anyone else got any funky restarts going on, for whatever reason? I basically want to start seeing what would trigger this behavior. I started uninstalling stuff one by one trying to figure out why its doing that but sometimes it boots up fine, sometimes it boots but doesn't ever find tmo's network, and sometimes it just does the above.
Observations:
1. It will always boot up fine if the SIM card is out.
2. The last time it did it was today while I was at work, listening to music while the phone was charging. Im noticing that the phone gets pretty hot while charging and really hot if you're using while its charging (getting apps, surfing the web, playing games, etc)
So any thoughts from the tech gurus here? anyone have similar behavior in the past on other phones? is the heat affecting the sim card negatively? I can (and have) put my simcard back in my treo 680 backup phone with no issues whatsoever.
New observation, it consistently does the reset process as soon as the "Adjust Time and Date" as it registers/syncs with the network.
UPDATE: so, i did some research, ended up at the setCPU thread and saw that when set to OnDemand some people's phones experienced similar tendencies. Problem is, mine was already set to auto-detect and "Conservative". I un-checked start at boot, and tried again. Same problem. I uninstalled setCPU completely and my phone appears to be back to normal.
I'll update again if anything changes.
so one of the things that i removed during my troubleshooting was my corporate exchange account. When i added it back. it did its initial sync fine and gave me my calendar and contacts. I then rebooted and the problem came back.
I removed the account and rebooted. it went through two cycles of the restarts and on the third one, it worked. I left it alone after that.
I then was showing my friend some things (browser differences) and had 3 browsers open. It froze as i went to close Dolphin HD. Rebooted and now its back to the cycle.
Mine did this also. Installed several apps, woke up to find a slow phone. Resets galore. A quick reset to defaults and app restore fixed it, sans setcpu of course.

my phone resets itself also as described above, but not really doing anything in particular. i dont have a whole lot of apps installed. i even was using google maps the other day and after it started up the screen went black and the device was unresponsive until the screen came back and it said searching and the media scanner was running.
well first off thanks for responding lol. i thought i was by myself out here.
secondly, i found that if i leave it alone and let it go through its cycle, it does eventually boot up ok (this is recently, before, it was endless). i havent restarted my phone (im afraid to lol) since it did it on its own yesterday (showing my friend the browsers).
since yesterday, i've used it for navigation (motonav), serveral installs, downloaded podcasts, rss feeds, etc and its been ok (even while charging and wifi on). again, havent actually restarted it since yesterday because its actually functioning for once.
Lastly, i unchecked the auto update time and date from network in the settings just to see if that makes a difference because based on previous expereience that is the point where it freezes and resets. Thanks for chiming in and let me know if there's any other advice you have
I'd suggest a reset as mentioned above.
Been checking out this site for awhile but this is my first time posting, today my phone started to have this problem and it just bootloops touchwiz if i have a simcard in the phone.
It works fine without a simcard but my problem is it will not let me turn of auto update of time and date, i have tried disabling this setting and it just enables itself again. I have also noticed that if I started messing around with time and date settings even without a sim touchwiz reloads once. I guess im gonna give a reset a go.

sorry, noob question (i came from winmo and a touch pro 2), what does "a quick reset to defaults" mean? is that like a factory wipe i.e. phone will be brand new again, gotta root again and reinstall everything, change settings, etc?

Root will stick but settings and apps/app data will be gone. It briefs you on what is and isn't lost when you do a factory reset.
Smae problem, its setcpu!
SetCPU with any settings will do this.
It needs an update, the auto detect some how loses and
will set the cpu to 19mhz max and min.
This is too slow to process. I rebooted and pressed settings and uninstalled it
while I could. Seems to behave once out of touchwiz.
For me it was another app not setcpu I never used it. After i did a reset i restored all my apps with titanium backup and once i restarted my phone it looped again. So i did another restore and left off all the apps that i installed right before the problem started and so far i think for me at least one of these caused it
Google maps update
google translate
the extra language pack for translate
barnacle wifi tether
hero of sparta
these are apps that I installed right before the problem happened and without these my phone works fine I am going to see if i can find that one that caused my problem.
It's not the maps update because my phone works fine with it.
It was hero of sparta a gameloft game from there web market funny thing is its suppose to work on the vibrant while dungeon hunter which works fine would only give nexus as a check out option. Anyway im going to try to get a refund tomorrow.
I get the same touchwiz reboot but for me it has only ever happened while using google maps. I do not use set cpu, but I have applied the gps fix. It is more than a little annoying. I have done a system wipe but the problem persists.

yes, if you have setcpu, uninstall it - its buggy with the galaxys
- sometimes you can't wake your phone (if you set a screen off profile), forcing you to do a battery pull
- constant launcher restarts

and this is why i started the thread, to make sure i wasnt all alone. i have everything you have installed as well, but it was doing it before i picked up hero of sparta (and nova, and asphalt 5, man those guys make some good phone game lol).
anyways i just installed barnacle wifi tether yesterday so thats not it either (at least for me). That leaves the google stuff, out of the apps in your list, all of which were installed when i first got the problem, and are still on there after I've removed setCPU

ok so, contacts, text messages, etc stay? Meaning if i do a factory reset, root stays, and all app stuff can be taken care of by, say, AppBrain since it has a running list of everything installed and knows where to get it to install it again? I apprecicate the advice, but this would still be a last resort sort of thing. my phone has worked fine for the past few days but I also havent restarted it yet either
just a quick update, my phone still does this if i reboot my phone (which is never now that i got my 32gb sd card), but for the first time ever hero of sparta caused it to happen while the phone is on. I uninstalled it so we'll see.
When I go into the settings to enable wifi I get the following messages back to back, either one can show up first:
"unable to save the network"
"unable to scan networks"
When this started the phone was not rooted.
I rooted the phone in an attempt to fix this.
I deleted /etc/wifi/wpa_supplicant.conf after backing it up.
This fix was suggested in the EVO forum, however it did not work for me, also the wpa_supplicant.conf was not recreated, and I was under the impression that it would be.
Has anyone had this issue and fixed it without doing a factory reset?

Now that you are rooted, i would say do a nandroid backup, then do a factory reset to see if that fixes your issue, if not, then you have a backup to restore to incase it does not work, if it does, then your good to go, if not restore and you are no worse off.

How do you do a NANDROID backup? Using Koush's recovery image? I saw initial unstability issues so didn't bother with it. I'm still hoping to see Amon Ra's recovery.
oh jeez i'm glad this thread is here. I have the exact same problem now. I don't remember anything significant enough to screw up the wifi, but I did use XBMC and Allshare as a trial run and it worked fine and I was amazed.
The next day the wifi is gone and 'unable to scan networks' gets on.
Can somebody help with this issue?
I will nandroid back soon and see how it goes down.

that is a link to the how to, just follow the first post, once you have clockwork recovery installed do a nandroid back up through ROM Manager,(if that is the koush recovery you said you had your set, just install the app) try a factory reset after backup and see if that fixes your problem, if it does then your set, if it does not fix it, then you can always do a restore and it will put your phone right back to how you had it when you did the back up.
Just ensure that you dont partition your sdcard with the rom manager, it will wipe your whole phone internal sdcard, not the external one, you should have no reason to do this anyways, just wanted to let you know not to try for fun. as it is not one of the steps to backup or restore anyways.
I had the same problem and found that the problem seems to stem from Allshare. I used it briefly and disconnected from WiFi, later that night, I enabled WiFi and had this problem. Today I opened Allshare and it prompted me to turn on WiFi, I was redirected to the WiFi menu and attempted to turn it on again. Of course it failed the first time, but I repeated this process of opening Allshare and pressing "Back" when it tried to redirect me to the WiFi menu. Doing this two or three times somehow managed to get my WiFi finally to recognize and now it all works. I would say, that if anyone is to run into this issue, I think it's Allshare related. This is what I did to fix it, hope it helps.
thank you for that. i'll go try it out
None of that works. Does any developers or anyone with some experience have any advice or fixes? Much appreciated.

I'm pretty sure it had something to do with Allshare or XBMC. I think it has something to do with the phone having to scan a network for other devices to obtain indexes. When I was messing with allshare, I disabled the wifi in the middle of the phone attempting to scan my network for my media servers. That's the only thing I did, so it's the only thing that could have caused my issue. When I opened allshare again it asked me to enable wifi, I received the error a couple of more times then after a few times it fixed itself, which led me to believe that it was allshare that caused the issue to begin with. I'm hoping that samsung is aware of this bug.
Same issue, first time I restored a Nandroid backup to get things rolling again. This time I was testing a new DLNA server at home with AllShare, since then Wifi wont stay on. I have sent a message to Samsung support about it. Rebooting doesn't seem to help, not sure how to do a workaround.
Best thing is to go into AllShare, make sure Wifi is on, wait a few seconds and then go to home screen. Usually after a few tries the Wifi setting will stick.
Like I said, all I did was to try and go in and out of Allshare back and forth between the Wifi application and enabling/disabling Wifi. After a few tries, it magically enabled successfully and worked. I wish I had a better fix or better advice, but all I can say is that I just had Wifi disabled, attempted to launch Allshare, Allshare told me to enable Wifi, so it automatically took me to the Wifi settings menu, I enabled it, received the error, went back to allshare, it sent me to settings again, I enabled wifi again and immediately pressed back to get back into Allshare, at which point I just bounced back and forth between the two, hitting back immediately to get back into Allshare, and somehow Wifi worked. This leads me to believe that Allshare didn't finish "something" with wifi, so interrupting Allshare in the middle of a network scan is bad.
already returned one unit to tmobile because of this issue a couple weeks ago had no idea it was related to allshare. makes sense i was using it to try to stream to my xbox the day before
Looks like a pattern to me!
Also, if you are using Juice Defender, you may have a setting that is turning off WiFi.
Fixed for me
So I had the same problem. Not with allshare, never use it. Just randomly stopped working. Anyway, follow the link below, it fixed the problem. It does require root and editing the conf file rather than deleting it. I had a missing } from the end of one of my entries for some reason. I removed all of the saved ssid's and put in the missing } to the end of the t-mobile entry and no more problem!
I can't post links so change the below hxxp to http

I'm rooted, deleting that file worked fine for me and it was recreated (the one early in the thread)

It's worked . Thank you so much.
none of the "fixes" posted work. im bone stock, running eclair. same wifi errors as the op. The phone is to be used as a wifi only device, since the sim is not active. is there a real fix for this?
This is helpful information. thanks.
I'm on the latest non-rooted stock. Lately, I've been having lots of serious bugginess and slowdown, crashes, all sorts of issues. I've had this tab since 3 week after it came out, so it's been a while. I've though about wiping it and starting over, but I don't know if that will fix my problems, and doing so will force me to have to reconfigure EVERYTHING, since Google still allows us no local data backup system and their supposed cloud data backup seems to only remember minor settings, and often doesn't work at that.
(seriously, you'd think they would at least offer some sort of explanation about how it works, what it backs up, or even just let you log into their services and see what's been backed up. very odd for a cloud computing company to be inferior to the iPad's backup system right now....)
I honestly don't want to root, because I keep seeing posts about glithces and serious malfunctions resulting, and honestly I don't have time to deal with it, I've rooted 3 phones and it's just a pain to unroot for updates, hope it gets rooted agains, without bugs, etc.
So, does anyone know what the cause of these problems may be, if it would be fixed by wiping and restarting, any other ways to fix it, etc.?
Making a backup now will only backup your issue
Sounds like a rogue app is causing your issues.. Chances are if you did a backup. then reset your device. If you restore a backup you will put the problem back..
Its not that much to allow google to reinstall your purchased apps back from market after a data wipe. I say go for a tablet reset.
Then consider a backup before you have a Issue.
Good Luck
Would be helpful to know what problems you've had and in what programs.
Reset to factory dude...
You loose all settings, apps, but at least you come back on a fresh tablet without anything making trouble.
I got a weird problem a week ago after updating the leaked version of ICS my tablet was starting, then after unlock screen, between 1s to 1mn of playing (not game, just using the tablet like usual) the tablet was rebooting...
tried many times... to see what happenned..
so I go fast as flash and reach RESET TO FACTORY
and VOILA... problem solved.
I'm in similar boat with you, I'm on the latest stock, and have some problems. I did a hard reset, as soon as I setup my google account, google push some settings back, even the wifi settings. But nothing really got fixed. I have map crash like crazy, and I got a new problem that the gps logo in info tab at bottom kept blinking, while I had nothing running. Really got tired with all these problems. I thought I didn't install too many apps other than some basic google's apps. Somebody pointed to the Latitude for the gps logo, but I didn't have that on at all, not logged in. I found enter/exit navigation sometime will help.
Hello,
I noticed this problem a few weeks ago. For some reason, my phone (N9005) has no problems connecting to my home WiFi and a few other ones that I have saved, but when scanning it doesn't show any other WiFis except the ones that I have saved, it's like it isn't even scanning. I tried to delete my home WiFi off of the list and sure enough, when I scanned it was completely gone and the phone couldn't see it. And then I manually added the network and it connected without a problem.
If anyone has any input on why this could be happening, it would be greatly appreciated because it is a huge pain in the ass, especially when you're out and about. Thanks in advance.
This being XDA forum, first question would be is your phone modded?
My wild guess: it could be some software interfering. Why don't try to boot in safe mode, just like windows safe mode, should load minimum programs and if it works then it's one of the programs, if it doesn't then I would wipe cache.
Yeah, forgot to mention that. It's only rooted with De La Vega, everything else is stock. I removed some of the bloat with Titanium Backup, but that's about it. I do remember that stock Messages app started FCing after that so I ended up removing it too, maybe I removed something that messed up the WiFi as well?
Tried the safe mode thing, but it didn't work. Deleting the cache didn't work either.
In that case I would go on a limb and suspect you deleted something you shouldn't. When I was going over the list of programs to stop from booting, for many of them I couldn't find any references, what they are for, so I left them alone. What I would do if I was you, I would reload everything back to stock (I think you can do that without tripping Knox) and then freeze those programs instead of deleting, so you can always unfreeze them if things go south. Also some of the programs I don't use now, I may find useful in the future. IMO the phone is powerful enough and has enough memory and battery power to handle little extra bloatware, no need to go Spartan.
So, i just bought from a friend a Moto G4 Plus almost brand new, everything working great.
But this morning i realized my notifications dont show, i cant pull down quick settings, home button and recent screens button are non responsive and i cant see the lock screen anymore; I try to unlock my phone with the fingerprint sensor but it unlocks with any fingerprint or even just by pressing the on button.
With all these problems, I went online to search for possible explanations for all of this. I tried to factory reset it but the button is a little faint and it wont let me. I tried to hard reset it but it also wont let me do that. I uninstalled all the apps i had to see if any app had done this but everything still wouldnt work. Also tried deleting all other information but still, home button and all other things dont work and still cant factory reset.
Also tried factory resetting it with two different programs conectting it to my computer but neither program recognized my phone even though its battery was over 80%.
I am getting really frustrated. I mean, everything else works fine, but all these things should work and everything and its really frustrating trying to use the phone having to go back on everything to go to the home page.
Anybody have any suggestions or have had the same problem? Tomorrow im gonna take it to a guy i know who fixes phones but would really love to know if i can solve it myself.
Thanks in advance

Just did, and int fixed everything, home buttons working, quick settings are coming down and all the other things.
But, now my network connections are unavailable. My mac address is 02:00:00:00:00:00, my ip address shows as unavailable and my phone also wont read my sim.
I already flashed it again and also tried restoring it to factory setting because now it lets me do it but nothing changes. I cant connect to anything on Wi-Fi, it just stays on the screen of Wi-Fi turning on
I had same issue when memory bocame full! I did hard reset.
