[Q] Wifi, network, or hardware issue? I747 - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

First of all I have done everything to find an answer to my issues, I've looked in a lot of places and searched a lot of different ways.
The last thing iI wanted to do is post here but don't even know how to ASK about my issue.
I have an AT&T i747 running task650 4.2.2 with underwear kernel.
I am using a ST LTE sim.
Even before I got the new LTE sim I had this issue.
My problem is my phone is getting bad network issues when leaving wifi on, but like when I leave my house, where I connectto wifi, it takes forever to get cconnected to a network if I do get connected at all.
Recently my phone is now displaying NO NETWORK even, like when I try to make a call in my house.
And when I leave my house I won't get a network sometimes unless I turn on and then off airplane mode.
I'm sure someone else has had this problem, maybe I'm just searching with wrong verbiage idk..
I don't even know what to call this problem let alone now how to fix.
If someone has an answer that would be cool.

A few questions about the GNex - Network, Mail etc.,

Hi Guys,
So, I've been using the GNex for about a month. I moved to this phone from a Moto Atrix and here is what I have noticed and have looked around but didn't see any good answers to these questions I am having. Hopefully I get some answers here.
Device info:
GNex GSM version on ATT.
Running JB 4.1.1 Stock with Trinity Kernel (rooted and bootloader unlocked).
Issue #1: I get really bad reception at work. But, when I leave the building, my phone doesn't automaticaly connect back to the network. Sometimes, if I don't check my phone, it's been like that all night long until the next day when I have tried to make a call and it said "No Network Available" and I have to either reboot or toggle airplane mode to get back on the network. Am I missing something? In my past experience with other devices, they try to automatically connect back to the network when they loose connectivity. Also, if I get in an elevator during a call and the call gets dropped due to network unavailability, it doesn't connect back to the network and I have to toggle airplane mode. Has anyone else had this issue?
Issue#2: This is with the stock mail app. Specifically the search in this mail app. No matter what, it always returns zero results. Has anyone had this issue with the Mail App? If I use the Gmail app, it works fine. That's what I am using now, but am curious as to what I may be missing that make it not return any search results in the stock mail app.
Q3: Speed Dial: How do you set speed dial on the dialer? Is it even supported?
thanks in advance,
vG

it could be to do with your radio, what version is it? baseband version in about phone. im no expert but when i flashed a jellybean rom i had to update my radio afterwards cause my signal was dropping alot. i also had the same problem later on but that was down to my network operator. before i realised it was them i googled my problem and a few forums suggested that my sim card was goosed. so maybe check those three possibilities? i cant help with the other two issues unfortunately but good luck sorting it out!

Network loss

Ok guys, having a real problem here. Often when I am connected to either 3g or wifi my phone will stop picking up signal suddenly. AIt's almost every time and I will have to disconnect from the network manually and reconnect and it will instantly pick up signal again for a while then it'll repeat. When it suddenly stops it doesn't show on the status bar that I have lost any signal. With 3g its kinda just at a stand still not receiving or uploading and with wifi it just stays the same but I'm still not picking up a signal because by web pages won't load neither will other apps that require network load until I manully disconnect and reconnect. Is anyone else having a problem like this? I don't think it was like this when I firs got my phone a month ago. I'm at a loss. Any help is much appreciated. Oh I'm completely stock btw haven't rooted........(yet) lol

It has happened to me a couple times that I have noticed. I will be streaming music and walking and all of a sudden, nothing.
Even a soft reboot does not help. It will require a full reboot generally to solve the issue. I have not been able to identify the issue specifically. I suspect it might be related to LTE testing in my area.
What's the LTE status in your area?
No lte yet but as I stated earlier it happens on wifi too. It'll still show that the signal is connected but my pages want load at all after it happens and when I try to refresh it'll say that the webpage could not load because there is no network. Only until I manually shut off 3g or wifi in the settings and turn it back on will it pick up signal again but only for about 5 minutes. This has happened in various locations on 3g and wifi and will even happen at home wifi.

This has happened to me as well... A lot . Stock.. on various roms.. No lte as well.. But it's in the works
-TeaM VeNuM Like A Boss
-Galaxy Note II Edition
I've had this problem too. Sprint replaced my phone and it never happened again.
I think reactivating hands free actually fixed my problem...for now anyway. It's not losing network like it was before. All I did was enter on the phone dial pad ##72786# that'll reactivate. Hope this helps

Not connected to Mobile Network after being on Wifi?

This has been a frustrating issue I've been having pretty much since starting up my T-mobile service about a month ago.
To start off, my G3 is unrooted and on the latest stock software version, 20e.
I use Wifi calling often because I get 0-1 bars of reception at work. All seems to work well until I go outside and try to make a phonecall over the voice network. I'll have plenty of signal bars, be connected to 4G even, yet when I try to use the phone dialer to make a call it will say "Not connected to Mobile Network." or something along those lines.
I haven't done extensive testing, but I believe the other day I toggled the "Mobile Data" off then back on and was able to make calls.
Has anyone else had this trouble? Is it something possibly to do with Wifi and/or Wifi calling?
I believe I could make a phonecall using Hangouts when I was off of wifi, which tells me that the data part is working, but not the voice network.
I contacted T-mobile support, but they just had me do the "typical" things, like shut down the phone, remove the battery/SIM, start everything back up. And sure enough, it worked after that, but I'd rather not have to restart my phone or toggle stuff to get it to work as it should without any hassle.
Thanks!
My wife has the same problem after the 20E update. Her mobile is stock as well. It did not happen on 20B.

Off the top of my head no. I'll dig around a bit and see what if anything I come up with.,
From the digging I did I can't seem to find any help. The only thing I can think of is to factory reset it thing and see if it helps. I am going to do do it on my wifes phone tonight.
Yeah, that's what I was thinking too... I'm not really in the mood to deal with restoring all of my apps and whatnot, so I'll hold off on the factory reset for now.
If you remember, could you let me know the results? If I know for fair certainty that a wipe will fix the issue, I might do it.
Thanks!
It's a network problem and it is worst on Samsung phones. I recently went and got a new sim card and it seems to have fixed it. I read it is because if you live in a area where there is poor coverage it causes your sim to where out fast.

This started happening before my first month of T-mobile service was even up with a brand new SIM. I'm not saying that it's definitely not a SIM issue, just would seem unlikely that it's worn out that fast.
Mobile out of Network-Tmobile - Android
I;m having the same issue, turned phone off and on, checked Network connections everything looks fine, but now able to receive and send texts or make calls.

Calling issues

Just wanted to see if anyone else has been experiencing this or maybe knows a way to fix this. I have 2 issues with the phone calling on this phone. I had the 925T since launch and never had an issue with it. ever since i sent it in for repair, I've had a strange issue. Fist one is dialing out. When attemting to make a call, it takes anywhere from 3 seconds to 40 seconds before the call actually gets connected. this is highly annoying as i dial a number and it feels like forever before the call actually connects. my other issue is after the phon ehas been one for a few hours, I dont get any incoming calls. the phone will not show me any incoming calls at all so I don't even know when someone calls me. Ive tried everything i can. tried changing sim cards, updated the bootloader and modem, tried different roms, kernels, stock odin, everything. and its the same story no matter what I do. Anyone Have an idea of what it could be? It only works well after a fresh reboot. calls works without issues. hours later, problem comes back
I've had the same exact problem but I attributed it to using an AT&T Sim card on an unlocked T Mobile phone.
I've now rooted and installed Xtrostolite Rom with latest modem and bootloader. I've yet to have any issues. Good luck.
Anyone else have this issue?
I have this issue. It seems if i leave wifi off i do not ever have this issue. I live in a crappy coverage area so i have to have wifi on at home. I just reboot when i leave. I hate this phone....

You think the problem is WiFi related?
Yes. If i leave wifi off i never have the issue.
Still is happening. whether I have wifi on or off it always happens. It seem,s to be an issue related to VoLTE. When I turn LTE off, the issue dissapears. Updated baseband and bootloader to latest version and issue is still there. Have a custom rom and the issue is still there. go back to the tmobile rom and the issue is still there. thinkiing of going back to a tmobile firmware and turning off VoLTE in the firware then reflashing back to custom rom and seeing if that helps. if not, im selling the phone and getting the F version of the regular S6 and calling it a day. im done with carrier branded phones.
Interesting enough I haven't had this issue in the last 3 to 4 days. I wonder if it is AT&T related.
I have this issue. All the time. Unlocked from tmo, using straight talk at&t. This phone is the worst.
Anyone not on AT&T network having this issue?
I wonder if flashing the AT&T modem on TMO model will help.

Maybe you should get a phone from att.
If att service is better than tmobile then maybe there phone is better than tmobile's phone.

I've been able to switch between carriers on any phone that has the supported bands since the galaxy s2. The issue is with this phone. My mistake in buying it.
Please help!
same thing here its unbearable, using latest unibase and xtrestolite
I have tried a few roms and a few kernels. I have tried differ apns but att Sim in this phone doesn't work like it should. I was going to get a TMOBILE note 5 to use on att but now I know it's not worth the risk.
@stu5797, yea man, I wish I had a solution. I'm happy it's not just me, but pretty bummed that there seems to be no answer other than it just doesn't work properly.
I've noticed the issue only happens during peak hours. Can anyone confirm?
I was having similar problems after the 5.1.1 update so after a few troubleshooting sessions with TMO, they sent me a new phone. 2 weeks now and no more problems. First phone that I have not rooted and flashed..... I was also told by a store rep that a lot of people were having issues since TMO is upgrading towers for 12 band.

Are you still having this issue? I have the same issue and the same phone but mine is unlocked and working on cricket network. So yeah same problem taking forever to connect a call and no receiving calls mos of the time. No ring no notification of missing call. I been doing some research and find a temporary fix. Try going to settings -mobile networks and switch from lte/wcdma/gsm to wcdma/gsm or gsm only. But before do a test. Turn off data and try to make a call see how fast it connects then have someone to call your phone. If it works then this trick will work for you. Of course you gotta sacrifices lte speed . Basically having 4g only but at least will fix your calls. These problems seem to ve related to volte i been trying to disable it but there is no such option under phone app setting. I just dont have it. (I cann show some screen shots) so if someone knows a secret code or app whatever to turn it off i will appreciate it. My phone is a t mobile galaxy s6 edge.

Didn't work for me. I turn off data and I still have to wait until the call goes through

Mobile Data stops working

Hello,
I live in an area (like many of us) there T-mobile service isn't that great. I daily drive through areas with zero service and I have almost no service at my house so we utilize WIFI Calling.
I have been finding for the past few months that when I return to an area of good service (phone showing full bars of 4G or 4G LTE) that I cannot move any cellular data. If I reboot the phone then everything works again for a while. I have tried to toggle into airplane mode and back but this does not help, only a full reboot helps.
Does anyone else get this? Its very annoying to have to reboot the phone when I need to use cellular data. Appreciate some input. Phone is NOT rooted and running the latest available software from T-mobile

It happens all the time for me. I've not been able to figure out why it happens, but I've seen some speculation in other threads where people think it can break when switching between H+, 4G, LTE, etc. Some people have reported that switching to airplane mode and back fixes it, but it doesn't work for me. Only a reboot will fix it for me.
Here is another thread with some discussion on it:
http://forum.xda-developers.com/galaxy-s6-edge/help/mobile-network-data-connection-drops-t3097605
Thanks for the response. I'm not happy to hear it appears to be happening to everyone. I wonder if any of the carriers have reported this to Samsung?
I cleared the cache partition on my phone 2 days ago and I've been good since...that doesn't mean it fixed it but its been a while since I had 2 good days!
THIS HAPPENS TO ME OMG!!! I thought I was going crazy... it happens quite often in NYC where we travel by subway underground... Switching to Airplane mode then back indeed fix it majority of the time, but it doesn't work sometimes...
Also, this happens when i am on Wifi for extended period of time, and then leave WiFi, the phone will show 4G LTE but wont' push any data.
Going into Phone status will show that you have no IP Address...
edit: btw, i've done an exchange with Tmobile, and still happens on the phone, Swapped SIM card as well, doesn't solve the problem. T-Mobile ran diagnosis, and found nothing wrong. I suspect it might be T-Mobile's network configuration...
Also, I can almost 100% reproduce this when I am playing a game that requires periodic connection (like loading acount info), and then playing in the subway while doing data connection between subway station (we have internet at the station, but not in the tunnel) will break my 4G LTE data connection...
