Hi,
My phone is Galaxy S3 t999l. I've used this phone on various ROMs (JB, KK, and now LP), but no matter what ROM I'm on, there seems to be a weird issue when I'm using WiFi. That is, some messages don't get through. I have a social app that sometimes can't send messages while WiFi is on. If I turn WiFi off, it sends without a problem. But, other times, it can send messages just fine even with WiFi on, so it's random. I've had the same issue with my hangout/sms messages. Can anyone shed any light on what the issue may be and any ways to diagnose/fix it? I'm really hoping it's not a hardware issue.
Thank you,

Hello,
I've searched around the Epic 4G Touch forums as best I could, but sadly I couldn't find anything that was exactly this problem (although I found some interesting articles about wifi sleep time but they don't seem to apply). I'm experiencing an annoying issue where I can connect Wifi just fine, but if the phone is left for a small period of time (~10 minutes), wifi appears as if it's still connected, however it cannot send/receive data. When this happens, the wifi status says it's "connected", but there is no data connection. The only way to to get the data back is to turn off wifi, wait for 3/4G connection to initialize, then turn Wifi back on to refresh it...then it's fine again until I set the phone down again.
I had this problem on stock EL29, so I rooted and flashed Phantom Blazer ROM (very cool ROM, but I'm still experiencing the same issue). After reading the threads on here about wifi sleep times (apparently they're backwards with ICS roms), I've experimented with every setting, yet I still have the same issue--Wifi is fine as long as I'm using the phone, I set it down, after about 10 minutes pick it back up, says it's still connected, but no data connection.
has anybody experienced this problem with this phone? I'm about to unroot my phone/go back to factory so I can take it in to a Sprint store, the problem is they (trying not to be offensive) don't seem to know very much about this device. I thought I'd ask the pros before I return it, get an iPhone, and have to eat my words about how cool Android is vs. iPhone in front of all my friends. I'm hoping there's a reliable ROM or app that can resolve this vs. having to just replace the device!
Thanks for your help!
I'm not the only one
I'm not the only one with this problem:
edit: I can't post links to androidforums.com or anywhere else, but this same problem is all over the interwebs and nobody has a solution.
I'm sure it's not my router as my ASUS tablet/laptops/girlfriend's iPhone experiences no connectivity problems. I'm thinking this is a hardware problem with some of these devices. I will unroot/reset to factory tonight and let you know what happens.
What channel is your router on? And what type is it A/B/G/N?
This is s known TW ICS bug, most likely kernel related. Almost everyone is having this issue and there is no fix until Samsung decides to repair it. There are quite a few posts similar to this one. If you're using XDA's search function, it's not very good. Try using Google next time and search XDA that way.

Hey guys, thanks for the response. Just before I unrooted/reset to factory I tried one last solution--download an app called "Wifi Fixer". It has resolved a lot of these problems. It's not 100%, but after testing it for a day so far, I've only had to manually refresh the connection once or twice. It's a lot better, even liveable, and I won't be resetting to factory afterall, at least not until Samsung provides an update. So if anyone is having the same problem, try Wifi Fixer, hopefully it gives you a similar level of success...I'm not super happy about having to run another background process all the time, but it doesn't seem to affect battery, and the fix it provides is worth it to me.
Cheers!
Huh - a couple of things. Noticed this problem crept back in FF18 and didn't know why until I went back and checked the wpa_supplicant.conf that I'm using. The line ap_scan=2 was missing; after adding it back in the signal strength is back to full and stable.
I'll bump the thread but it appears the config changes here still hold after all:
http://forum.xda-developers.com/showthread.php?t=1569348
This should also avoid having the WiFi fixer there as you can specify the country in wpa_supplicant.conf manually.
Thanks for looking in to this! A couple questions from a noob like me though:
When you say the problem crept back in FF18 ... what does that mean? Is that something that exists in the "stock" version of the Epic 4G touch from Sprint?
The manual config file tweaks you're describing ... is that something I can perform myself?
Basically I'm wondering if it's "safe" to revert to stock in order to get consistent wifi signal, or if it's something I'm experiencing because of the ROM I'm using.
Thanks!
**Baseband I927UCLJ3** sorry if that threw anyone off.
Hey guys, I am wondering if anyone has experienced any wifi connectivity issues on the new update.
I dont have any issues connecting to wifi, but for some reason, it wont stay connected for very long. It seems like after I go out of range, it simply wont connect to anything, and I have to manually connect to my network.
The problem is I have been blowing through my data plan, thinking I'm on wifi, since everywhere I go I am normally on wifi. But in actuality, because my phone hasnt been auto connecting to the networks, I have gone through half of my data plan in about a week.
This has only happened since the 2nd release of ICS. The first one work fine for me (expect the black light issue, which I didnt really care that much about).
Any help would be greatly appreciated!

Hello,
I believe wifi has nothing to do with baseband. Probably there is something wrong with your phone and the new kernel wifi driver...
I'd try removing the access point and re-creating it, and playing with the advanced wifi settings.
Also, try rebooting the router/wifi access point.

Thanks for the info!!! I looked more closely into the settings and for some reason it was set to turn off wifi when sleeping.
I feel a little stupid, but I'm glad I got it sorted out.
I really appreciate the help.
First of all I searched and didn't see anything on this, sorry if I missed it.
I am having a issue with my S3, it seems it randomly stops receiving calls and sms. The phone is only a week old and it has happened twice already.
A simple restart seems to fix this issue however I would prefer to have a device that I don't need to worry about restating daily to ensure I am getting my calls.

Any help would be great & thanks in advance.
you didn't search properly, as there is a thread about this already. it is a known issue on AT&T's end, so everyone experiencing this problem needs to wait for them to fix it.
It is a problem with LTE service, using only 3G is the only current fix to this.

No idea if this is the right place to post, new here, bare with me.
I decided to try one of the 5.x ROMs on my Nexus, and have been poking around with the Unofficial CM 12.1 by zzpianoman. Got it flashed and all, did a factory reset to make everything nice and fresh, and worked on getting everything set back up on it. The issue I'm running into, is that as soon as I turn on and connect to my Wi-Fi, my mobile data shuts off completely and won't connect unless I turn my Wi-Fi off, which results in all incoming and outgoing MMS's to fail.
I've read that the mobile data shutting off when on Wi-Fi is a feature, but that it's supposed to toggle back on for MMS's. I've even tried setting the Auto-Retrieve MMS settings in the stock messenger app, but nothing works.
If anyone has any insight or suggestions as to what might remedy this, I would be most grateful!

Hello,
I am experiencing constant WIFI drops. I flashed another ROM(LineageOS Official) because I thought it could happen due to the ROM. But nothing changed even after flashing a new ROM. I live in Germany and have Telekom Speedport W724V. I also saw other people having this issue and they mainly live in Germany. Is there any way to fix it?
Example of my problem:
I am chatting with my friends on Whatsapp. Minutes later, my messages can't be send, because I don't have WIFI. Sometimes it showes me, that I'm connected with the Internet, but it still doesn't send the messages.
I hope you can help me. For futher information, just ask me and I can send you every information you need in order to fix this issue.
Android version?
