GS3 Freezes after disconnecting from WiFi - Galaxy S III Q&A, Help & Troubleshooting

I recently flashed CWM onto my uncles GS3 and rooted his current rom. I made a backup and then tried out a new AOSP rom, which we decided not to keep because my uncle did not like it. But now, returning to the old rooted stock rom, every time the phone disconnects from wifi, it completely freezes up on the lock screen. Pressing the lock button does not shut off the screen and instead just locks it. You are unable to unlock it as the phone completely freezes up. The only way to get into the phone is to double tap home to get into the voice commands, and then go to home from there.
But even after that the phone continues to freeze. I tried another ROM on his phone today, but the problem still persisted a while later. It all happens when the phone is connected to wifi, and you walk out of range. After which the phone starts to freeze up.
I'm totally unsure whats going on. I just flashed the rom again, and we are trying a clean slate with no restoring of any data. It may have started to happen after we installed root browser (just as a guess), but we could be completely wrong.
If this continues again on this rom as well (which is Revolution HD) Im going to go back to completely stock (rom & recovery), and hope it still doesn't persist there. If not then I am out of options, and I have no clue what to do.
Any help would be GREATLY appreciated. We spent so many hours today trying to resolve this.
Thanks!

Usualy WiFi problems are kernel related. Have you tried Siyah or another custom kernel?
If this will not help than returning to stock with all wipes is the best idea, this should resolve your problem. If not, than you can try to reset router or set static IP for s3. Also try to remove WiFi setting for your home network in the phone and set it again manualy or via WPS mode.

Thanks for the reply. This issue has been occurring between two different roms, so can the kernal still be an issue? Its happened with the absolute stock rom (w/ root) and Android HD Revolution.
My uncle said he would play around with the phone and let me know if it freezes again by tomorrow. If it does im going to wipe and stock.

Can anyone show me where to get the stock roms for the i9300?
I've downloaded and tried 3 different ones, but the phone never manages to boot up!

Same problem on Galaxy Note N7000, did your problem resolve by reverting back to stock because I've tried every possible option, to no avail?

Go into recovery and wipe the cache, I believe that was my problem.

Bell SGS2 3G Data Connectivity Issues

Ok so I've been reading around in a few threads about this but haven't quite found a solution in my case and I think I need a second opinion. I've also posted in other on going threads but it just gets lost in the rabble so.... it now gets it's own thread.
Bought a brand new Bell SGS2 from a dude on Kijiji. It was brand new, still in the box with the plastic all on it. I SIM unlocked it (which required rooting it) and dropped my Rogers SIM chip in.
I can send/receive txt's but 3G data drops frequently and usually happens once I initiate a data session. My test case uses SpeedTest. I've only seen it complete a full test cycle twice... most of the time, it will get the ping, start the download test and 10% in, the data connection drops and 3G/H+ icon disappears. It takes about 1-2 mins for the data connection to return. I've tried market access or web browsing and same thing happens once a data session initiates.
I've installed a slew of modem/ROM combinations via Odin from XXKH3 to XXKI4... nothing... same issue. Seemed worse with KI4 too!
I've tried different APN settings, disabling fast dormancy and specifically trying to enable only HSPA bands. Nothing. Same problem.
I've since reverted back to stock BELL firmware and tried a friends Bell SIM chip and noticed THE SAME thing happening! So this would definitely tell me it's a hardware problem. It's been more than 15 days so Bell won't even talk to me as the return period has passed and I'm not a bell user so screw them.
I guess at this point, I should test my luck with Samsung but it's been rooted and even though I've un-rooted the binary counter shows 2 which means.... I'm screwed for warranty right?
U can reset the binary counter after flashing back to it original state by using jig. Google for galaxy s2 jig
Btw, why dont u just flash original samsung I9100XXKI3 rom? Which provide good modem. Check my signature, 'boot loop', theres a link lead u to installation guide with download link provided. All is there.

I personally found XXKI3 Modem to be best for Bell's SGS2 (currently using it on Telus).
Tried all the modems' including KI3... didn't work.
In recovery mode, fix permission, reboot and check the 3g again.
Try another method, flash cm7 nightly latest version #16. If the problem still exist, thats mean its related to phone's hardware.

Well I got it new out of the box but I had to SIM unlock it which required rooting and etc....
I did power-volume up-home... got into recovery mode and... there is no option to fix permissions. Keep in mind this is the stock ROM I put back on.
CM7 is another idea.... not against that.
Well. Maybe some failure occured during rooting your phone before. Install rommanager app from the market, open then select flash recovery mode, then select your phone model.. This will give u recovery v4 which will give u more option on recovery mode. This is the easiest way to get more option cwm. U will have fix permission option when u done.

i have the same problem i.e data loses connection. after a fresh flash of stock rom and factory reset , it starts working fine for a week or so and then the shyt happens again . i can tell u , its not a hardware issue, it more like a software issue.
i m not good at android but wen i used to run squid on a linux machine as a proxy server , i recall i had to clear a log file to make data flow possible every few days. i think android has a similar issues some logs files build up or some **** like that.

[Q] Device suddenly stops working and needs to be wiped

I have a serious issue with both my I9100 devices.
it suddenly freezes and requires reboot. when i do it, it stuck on boot screen (Where the yellow triangle would be if using unofficial firmware)
nothing helps, only wipe data. once I wipe, device loads fine and starts working again.
I tought at first its rom/kernel related, I switched everything and even tried stock rom.
it keeps happening...today, I tried to swap batteries as one got empty, I took the battery out of the stocked-rom device (after turning it off) and then later when i switched it on, it had to be wiped.
same as with my other device.
Anyone has any clue what this is about?
Its became a big issue for me, I cant flash/wipe every few days...
One device is on Neatrom 4.4 lite, the other stock-everything, both 4.1.2

u can just rewert to stock ICS 4.0.3 firmware on both the phones and check for the issue (whether its firmware related or any hardware issue as such)
thanks for your help,
It did not happen on 403, tough it didnt happen on 4.1.2 for some while either.
what else would you suggest me to test?

1) with 403 for some time once again to ensure no issues of freezing.
2)then a different 4.1.2 stock/custom rom altogether to check for the same(freezing) issue.
stay for some time on those firmwares and see (may be one or two charge cycles).
3) do not install any mods on top of the firmware, just stay stock and see
One of the devices is already back to 403, while the second one on stock 412
the hardest thing to tell if 403 solves it or not, as it happens occasionally, once in a week or two.
I tried two different stock roms, so that would rule out #2.
The weird thing is that wiping data is enough.
data is separated from the rom itself, yet it causes the entire device not to boot anymore.

[Q] Samsung Galaxy SIII (GT-I9300) International Crashing And Rebooting

Hi, I'm having a curious problem with my S3 and I've been unable to solve it. I watched the "noob" video and tried searching these forums as well as a google search with various combinations of the wording for my problem. Nothing matching my issue turned up, I hope I didn't miss anything.
I recently bought a S3 second hand (yes, i know, i should have known better). It was rooted and running some kind of custom ROM when I first turned it on, but I was willing to deal with it until I double checked the procedure for getting it back to stock and starting again myself (nothing against the original rooting and flashing, just like to know exactly what I'm running).
When I purchased the phone I obviously checked that all of the main things worked - calling, texts, mobile data, wi-fi etc. I get home and connect to my home wi-fi and start checking things out and setting stuff up. The phone randomly rebooted. I carry on after the reboot and about 10 mins later, another restart.
To cut a long story short, there is something wrong with the wi-fi. If I turn off wi-fi in the settings menu and reboot, everything works great. No crashes, no reboots. If however I enable the wi-fi about 50% of the time it will crash while wi-fi is activating. The other 50% of the time, it will crash as it goes into the screen lock (either via timeout or pressing the button).
I've re-flashed to it's stock version of Android (using the 'Samsung GS3 Toolkit and Odin), same problem. Anyone got any ideas?
Thanks in advance
You can try updating the modem and RIL to the right version for your country, search in general forum. If it still reboots then try with another wifi source - I've seen some routers cause problems on client machines.
If you do a factory reset when you flash the modem, plus you have the latest stock ROM on board, then any remaining problems are probably hardware.
Test it fully after the factory reset, before you add any apps etc.

After much experimentation and flashing of various files to my phone I have further narrowed the problem. I've still not solved it, but getting closer I feel.
After a clean ROM flash it works like a charm regardless of how much i use the wifi etc. It's only after the first reboot that the trouble starts. It will begin randomly restarting. If I perform a factory reset from recovery mode, it works again, but starts resetting again after a reboot.
Any ideas?

[Q] 4.3 disrupted wifi, now can't fix

Hi all,
I've been happily following the progression of ROM developments, since I got my P7510 (P4WIFI) and sampling a variety of ROM's up through the versions of Android. I recently upgraded to a 4.3 ROM and developed a problem...I could connect to wifi as always, but could not get internet access (wifi connected, but no browsing, play store, weather apps, etc.).
I worked my way back through a number of recovery backups, knowing that in all of them I didn't have this problem, but it remained.
In desperation, I unrooted and returned to stock and the problem was still there! I found a .pit file for the 7510, re-partitioned, formatted the partitions and reloaded the stock ROM...still no change.
Can anyone point me to a solution? I've googled myself stoopid on this one...
Cheers,
PF.

Try to toggle airplane mode on then off..not sure if it will work on our tabs...but it works on my epic 4g touch..this is just a work around though.
What stock did you return to...
I'll look around and see what I can find...
My first thought was it's a router issue. I've had the same thing happen to me and in the end all that was needed was a router reboot.

Thanks for the suggestion. I tried the airplane mode on/off, but it didn't help.
The stock version I'm on is Build number IMM76D.XWMPF (P7510XWMPF_P7510XSAMP1_HOME.tar.md5)... I believe the correct one for my country...? Not sure if that's a red herring, though. The problem occurred going from 4.2 to 4.3 and has stuck with every restore and rebuild I've tried since.

Tried the router reboot, no dice. Also tried connecting to different WAPs and the problem remains. I tried connecting to my SGS4 as a portable hotspot, which was working fine previously...identical problem...

[Q] i9100 wifi very short range

Hi all, my eldest kid's having a problem with the wifi on his S2 i9100 - the wifi used to work fine but has developed a fault.
The phone needs to be very close to a wifi beacon, ie within about 3 metres! So he needs to sit beside the modem to use it. I've searched but not found any solutions other than fitting a new motherboard, for now I've set up an old modem in his room as a network hub and wifi beacon, but any hints would be appreciated.
The phone is stock kernel, I had to fit a new screen some time ago but I've stripped it back down and double checked ariel connections.
Apparantly it was giving problems before the new screen was fitted - during the warranty period - but he didn't bother to tell me then!!
Re-flash the modem ODIN again

If no help, try to format every storage and flash back to the stock ROM.
If still no luck, get back to the SAMSUNG stock ROM it might help!
After all the try outs, if it still doesn't work, maybe the problem is with the Wi-Fi Antenna. You may need to replace it.
Just try to solve through flashing first!

It's not been modded, sorry I said stock kernel but should have said stock ROM (he won't let me root the phone!), have done factory reset and checked the Wifi antenna connection, the wire itself is unmarked with no sign of being trapped
TRY use ODIN to flash the stock rom again

back up first, and format everything (ROOT is recommended, full wipes are followed)
Try to use ODIN flash tool to install the original ROM, wish you all the best!
