[Q] Galaxy S3 I9300 Mobile Data Disconnecting Frequently - Galaxy S III Q&A, Help & Troubleshooting

I'm suffering from frequent mobile data disconnection problems. The wifi is working well. but when I turn on the mobile data, the data connection will be working for couple of minutes and then turns off automatically, showing the data balance pop up. The same happens when I switch from one app to another. Please help
I did the factory reset too. Sim card is working fine on other phones.

Why 3 identical posts in half an hour ????

Ok, I've deleted the other 2 posts and left this one as its in its own thread, in future though, please don't post the same thing multiple times.
Thanks

may be your wifi is switched on and is connecting to some open networks resulting this?

i didn't turn on wifi after doing the hard reset. so I don't think it's a wifi problem

samsung galaxy s3 wifi not auto connect to home network

Please can anyone help.
Up till a couple of days ago my s3 would automatically connect to my wifi signal at home as soon as I walked into my house, haven't changed any thing but it no won't connect until either I reboot or switch wifi off and then back on again . Tried rebooting phone which works for the first connection but subsequently won't connect again after sleep or at least the phone not being used for a while. Also switching wifi off and back on again works but as before once wi fi shuts down it won't reconnect by just swiping the screen and taking the phone off of standby.
Hope that was clear enough lol
Many thanks Ian

Reboot the modem/router and try again. If that doesn`t help press your wifi connection in settings and reinsert the password and reboot.

Yes I've found plenty of things relating to wifi issues on the phone but none specifically to this one so if anyone could help I would be grateful.
I assume you've tried forgetting the network and re-entering the details.
Also try playing with the Wi-Fi sleep policy, in the past this has caused some problems with the stability of the connection. Settings, Wi-Fi, menu, advanced.
Also it might be on the router side. Try changing the channel on the router, and if it's dual band set it to 2.4ghz instead of 5.

Back up data. Factory reset.
Update firmware.
Change kernel.
That's three possible fixes.

Im getting very similar issues with my s3 trying to connect to a dlink router, works fine with the netgear one though. Did you manage to fix?

I cannot seem to get the WIFI Sleep to work at all. Even when set to NEVER on when asleep I can see in the battery stats that WIFI has stayed on the entire time. Any idea why this is?
can you tell us the ROM and kernel you are using (if you are using custom)? I have never had any issues with stock kernel myself.
also, did you hide your wifi SSID? in the past, it might cause some issues...

			
				
I was having the same problem, try this.. Setting - wifi - advanced - keep wifi on during sleep - Always.
I haven't noticed more battery use,

if you want another option besides backing up your data, doing a full wipe, and reloading your data, try a different kernel...easy fix that seems to fix these problems most of the time...the kernel is responsible for your wifi, gps, bluetooth, cpu, gpu, etc...so swapping it out should fix an issue like that

[Q] GMail - No connection Retry

HI to all, I am having a weird issue, I have both devices (listed in my Signature) which happen to give me a No connection - retry error every time I go to check my email, or even if I go to the Inbox folders such as Forums, I am all the time receiving No Connection Retry.
- I have tried clearing cache and data ,restarting, email shows up fine, after a couple of seconds I get the no connection again.
- I also did a full wipe on my tablet and have done everything from scratch practically, a couple of seconds later I receive the no connection error.
- I have also tried a different wi-fi connection, and also tried a 3G connection and the issue still persists.
I am really at a loss with this as it is really annoying; is anyone having similar issues or might suggest another work around for this please?
Thanks for any help.
Same thing happening to me, and lots of other people too it seems. Please update if you find a solution!

LTE/Mobile Data problems

I've been having some issues that i wasn't having before. I've got the OPX for about a month now and it is connected through LTE but i can't access internet.
If i turn airplane mode on and then off, it works for about a minute or so, then stops to work.
Anyone experiencing this?
Everything is ok here no problem yet

check apn's
APNs are there and they are well defined, I have manually redefined them now -> Airplane Mode on -> wait a few seconds -> Airplane mode Off -> surfed reddit for a minute or two, all of a sudden "This page cannot be displayed: 'ERR_TIMED_OUT' "
I would think this is a network problem, but there is a forum thread in oneplus forums where people are complaining about the same as me, although they associate the problem to Wifi and i don't
Also, i don't know if it's related, but I've flashed the latest version from MasterAwesome, the problems started there, i thought it was from the ROM, so i then flashed OOS2.1.3-x, where i had the same problem, then 2.1.2 and still the same issue...
I'm getting something like that issue but very rarely and mostly on WiFi. It comes between sleep and awake states so maybe check out greenify and see if that is the culprit. Or any other app that's restricting any function through the waking of the phone.
My oneplus x detects wifi very well, but does not connect to mobile data. What could be the problem?
Uh I have a similar issue but usually when I'm in motion. (in guessing switching between cell towers) what's your network. I'm using Tmobile US

Same problem I had yesterday. Must have tried 10 ROM's all of them flashed fine and everything worked except cellular data. I had no data what so ever. As soon as I flashed back to stock ROM data worked fine. So there must be a step or something we've missed in flashing custom ROM's spent all day yesterday trying to figure it out with no luck. Finally gave up and went back to stock. I'll wait for the official OTA marshmallow update from Oneplus
I'm having this issue right now with full 100% stock. Does any of you have the problem solved?
Just wiped data + cache + factory reset, but still no luck. I've also created a ticket on OnePlus support.

Are you using 2 SIMs? Data does not work for me on SIM 2 Slot but works fine on SIM 1.
I also can't connect to mobile data. There is no LATE/4G icon in the status bar but if I pull down the notification panel, LTE appears above the network icon. I've tried in both SIM slots. None of them work. The SIM card works fine on other phones.

Did you tried an other SIM? Change Sim location?
Did you reset APNs in the back up menu?

Yeah, I've tried 2 other working SIMs and I've deleted/resetted APNs, even manually configured them (copied from my other phone).
Maybe you lost the IMEI. Try to find it with *#*#4636*#*#

I have both IMEIs (dual-SIM) when I do *#06#
I flashed the stock rom and it's working! I will try it for a few days to see if it's a permanent fix.
Android N, same issue with all ROMs.. tried everything, no luck lte doesn't work at all.
Hi!
I did rooted my phone and unfortunatelly there is one problem...I lost my data connection. I have wifi and I can make calls but mobile data is just not working at all.
I have tried some methods...restart, sim out and back and restart, manually pick the provider and restart etc... nothing works.
I did not flashed any ROM but using stock so its wierd.
Any suggestion for a solution how to get back my mobile internet connection?
Thank you in advance,
Tom

I simply removed all the VPN saved. It helped. But now I won't be able to connect to the internet at all. That's fine with me. You can try what the above user has suggested ...try to shut Location. See if it works.
Thanks.
I had this issue, turns out it was an app from the carrier that forces to connect through mobile data connection to check for status or something.
I just uninstall the app and use their mobile web instead, it's been fine since

thank u so much all of your suggestion i've done and successfull blocking any mobile data internet from my phone
and i added restriction app background data each running apps that consume internet through mobile data,:victory::victory:
During set up you are asked if you would like to allow apps to access to data even when turned off you need to un-check that option.

No Internet access / Network access denied

Really hoping someone can help me out here. My Mate 20 Pro has all of a sudden developed and WiFi connection issue. The signal drops out and within the WiFi settings I get error messages network access denied or no Internet connection.
My phone has been back to Huawei twice for repair and was still getting the same error message so assumed it was the router (all other devices connect okay). New router has been delivered today and I get the same error.
Has anyone else had this problem and does anyone have any ideas to resolve?
I have wiped the partition cache, forgot network, changed WiFi passwords but nothing seems to work.
Likewise having issues with mate 20pro and WiFi dropping and then not able to connect.
I've not looked into why happening as I find reboot phone works although major belly ache when trying to watch, chat or surf.

Each time my phone has been 'repaired' and a few times in between.
Only thing that seems to work is reboot and then wait a few hours for problem to return.
Access denied - reboot - repeat
Think that's me done with Huawei.......back to Oneplus
Ive been having this the last week or so, thought it might be the dns (adguard) will test and see, but if you guys have issues and are not using an ad blocker then it must be something else... weird.

I use adclear as as blocker..... didn't think this could be causing issue as it has only just started, I've been using adclear before update to emui 10
Was having this the last months and 2 or 3 System uptdates. Sometimes a reboot fixed the wifi, but most of the time not.
Wiping the Cache in recovery menu fixed the wifi Problems on my phone. No Problems since then!
