[Q] SGH-1747 mobile data connection problems - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hey guys,
First of all, sorry but I'm a complete newbie with this phone, however I've tried to do the necessary research and I think i've hit a block. First of all, my phone is a SGH-1747 (from the title) Samsung Galaxy s III 4G LTE or just Samsung Galaxy s III LTE which is network unlocked with original carrier being AT&T. I updated the phone to Jelly Bean 4.1.1 via Samsung Kies and everything went smoothly. It was originally my aunt's and I asked her to ship it to me here in Australia. So my current provider is Vodafone Australia and yes I do have a micro sim and can use the phone for almost everything except for the problem that I'm experiencing.
Okay so firstly I thought my problem was that everything I go on google play store via my mobile data (not WIFI), I was unable to update / download certain apps and it would give me a "package file is invalid" error. I've done researched tried clearing cache, cookies, data but nothing seemed to work. I also thought it might be something to do with only unable to download apps that are a certain size, seeing as I could download SOME smaller apps (like google apps updates, but not all) but it got to the point where I tried accessing apps that require an internet connection, and it won't load because of error "not connected to internet or you might be disconnected". At all times I am able to access the internet via internet browser and even search for apps via google play store. I also thought it might be app-related, so i tried different apps, no bingo. I can however download all these apps / updates when I am connected to WIFI at my house, can even access the games. Also thought it might be related to Vodafone not supporting 4G so I tried to change around the network modes but It didn't really make much of a difference... I've also tried factory resetting many times with no bingo.
So now i'm at the point where I don't know what's wrong with it. Do you guys have any ideas? Even vodafone people were unable to find a solution after spending about an hour trying to fix it with them.

This forum is for the i9300, nothing on here will work with your phone

[Q] Market killing 3G connection

I have a weird problem with my AT&T galaxy tab. For the past couple of days, each time I launch the Market, my 3G connection is killed and I can no longer access the network, and of course I cannot access the market. As soon as I kill the market app, my 3G connection comes back.
I cleared the data and cache of the market app, did not solve the issue. When I uninstall the updates of the market app (reverting to the original ugly market app), everything works fine, but it then automatically updates itself and the problem comes back. I assume this is a problem with the market app itself and not my device (hopefully).
Has anybody else experienced this issue and found a fix?
I am running stock ROM with third party apps installed enables (done it with superoneclick: root, enable third party apps, unroot).
I have the amazon app store installed, so I can still buy new apps, but I would like to be able to get updates for the apps I have purchased from the market.
Any help would be greatly appreciated.
Thanks!
What modem are you using? Does the problem happen when you are using wifi? I think the JMF modem that is available for overcome rom is weak and I get many dropped connections and slow data speeds.
I am using the stock ROM and stock modem, I have never flashed a ROM. It only happens with the Market App.
Same issue for me. I have a rooted stock rom.
I have the same issue. Also stock rom and rooted. When WIFI is on (and connected) the market works fine.
I have been beating my head against this since I bought one. I am rooted using....I think I used Super One Click......stock everything else with non-market apps enabled. I originally thought that Root had broken it; however, if I unrooted, reset to factory, I still had the issue.
After many hours at the ATT store and on the phone (and swapping the device once and SIM card twice) I had an epiphany. a Factory Reset does NOT wipe the Internal SD like I thought it did. It leaves /mnt/sdcard/ intact. So, just for kicks, I began looking at my folders here. I MAY have discovered something. Market started working after I restored this folder to it's factory content (deleted any folders having to do with Apps in general).
I can typically hold power, deactivate Data connection, wait a few seconds, re-enable, and I get 3g back (at least for browser and other apps, Market still fails).
I have PSX4Droid installed (PSX Emulator if you don't know). There is a folder here named /.psx4droid, so I renamed it to /psx4droid (If I remember correctly, doesn't the "." hide the folder......too long since Linux class). I then deactivated/reactivated my data, and the Market started working properly.
I am not sure if it has to do SPECIFICALLY with psx4droid or just the "Hidden" folder in general, but now my Market works. I have 2 more folders in this location (/.downloadTemp and /.FileExpert) that may/may not cause any problems. I will post my findings.
.....Okay, so I'm going to type what I write now....Market just failed. Now I'm renaming /.FileExpert....Let's see what happens......
Damn. Still fails. But I'm tellin' ya. There is something in this folder causing it.
Or maybe some app is causing it to break......I have Amazon App store installed, what about you guys?
I do have Amazon App installed.
Anybody with an AT&T Tab not having the issue?
Same issue here. I had the Amazon Appstore installed but uninstalled it probably a week afterwards. Rooted running stock, everytime I go into the market it crashes the 3g. I found a folder in sdcard/android/data that had a bunch of appstore files in it. I deleted that and still having the same issue. I have removed all 3rd party apps so I have no idea what is triggering this. Please help.
P.S. I can access the market on WiFi
This also happens to be sometimes, if you tap wifi on then off again your 3g should come back and work fine.
swyped from a galaxy far far away...
Unfortunately what you proposed did not work. The market is killing the network connection each and every time. The network connection only comes back when the market app is not active anymore.
Since everything works fine when the market upgrades are uninstalled, I really think it is a bug in the newer version of market. Hopefully, the next update will fix this.
Maybe when Gingerbread is out!
I'm thinking this has more to do with us having installed amazon appstore before it was supposed to be. Somebody is mad at us
Has anyone made any progress on this situation?
Sent from my SGH-I987 using XDA App
I really wish I would have made more progress. After all the trouble I had with the device with this issue, I was seriously monitoring the apps I installed and then testing the Market. I gave up after a while since I am on Wifi 90% of the time and hardly ever do I access the Market while driving. I still have a feeling that something in /mnt/sdcard is causing it. Like I had mentioned, I could wipe back to factory and the problem was still there. I seem to remember that it only started working proper after I had cleared this location of crap. I would think that a Market update would see a larger group of affected tabs than just a handful of us. This doesn't seem to be a widespread issue.
That being said......I have decided to move on to Gingerbread. Maybe that'll fix it
Hey guys, try this. Worked for me and my Data problems with Gingerbread
http://forum.xda-developers.com/showpost.php?p=13751694&postcount=6
Basically create a new APN inside Settings -> Wireless and Networks -> Mobile Networks -> Access Point Names. Only set the APN to "Broadband," save it (Menu button) and select the radio button for it. Instantly fixed my data issues.
Thank for the tip. Unfortunately, it did not work for me. I am running stock 2.2 and waiting for the official 2.3 update from AT&T.
Good Luck. I thought about waiting for the official.....but I also have a Captivate. We didn't get 2.2 until MONTHS after the rest of the world (I think it was like 5 or 6 months later). I didn't want to wait that long again.

Could you please report if the problem fixed with Gingerbread ?
At first I didn't have ANY cellular data until I created a new APN mentioned in the tagged thread (APN Broadband). Now I have no issues with Market. I wish I could trust AT&T to release Gingerbread in a timely fashion, but I know better. So instead, I flashed Overcome.
P.S. I really can't enough of the CRT lock animation......damn I'm such a geek....

[Q] Few issues for which I need help

Hi all,
I have been using my galaxy note n7000 for an year now. From last couple of weeks I have these following issues with my phone
Whenever I go to a roaming area, my screen flashes with a message "Refreshing SIM Data" and immediately I lose the HSPA connection. This message keeps popping up on my screen as long as I am in that roaming area. I have another phone (HTC) and it doesnt happen like that in that phone
Now this one is very scary, Sometimes when I am connected to 3g/hspa my screen flickers with bright horizontal bars and immediately loses the whole network (no net, no calls). And after a few seconds phone automatically restores the connection and everything is fine again. But may be after half a minute this happens again and phone gets switched off. When I switch on the phone again, it would have lost all battery and I am greeted with a low battery message. Wierd part is that if I charge my phone it shows the current battery level again. This thing happens probably twice or thrice a day.
third one is also weird, I can browse internet, download apps from play store, unconditionally. But if I try to update an app then things wont happen and I will get a message saying that app could not be downloaded due to an error 495. I did find this as a known issue in play store but in my case some apps get updates successfully but only some would not.
I have searched for this in whole of XDA Forums, but none of them worked. I tried clearing caches of play store etc. I even installed 2 to 3 rooted roms (both ICS and JB) but no luck. Now I am back on stock ROM but issues still persist. I also contacted network provider (Vodafone India) they seem console me by telling me that everything is fine from their end !!
Story end
2 seems to happen due to an issue with battery. Try a different battery
3. for error 495.. if you are rooted and have cwm.. then boot into recovery and do a wipe dalvik cache and try again. it usually works after that,
1. no idea about this.. i dont get any such messages.
thanks !
2. Yes, I will do so
3.I tried all these, infact wiped everything more than twice
1.
First got to applications then select plays store and clear data. Then do the same for play services. Try. If still no go the wipe dalvikcache from recovery and it works. I get this error every now and then,
I think you are running an old firmware, is that correct?
In general go to service centre and warrantee.
If you dont mind warrantee, root, make efs backup on and off the phone and pcodin a newer firmware.
If wipe and such, do only on safe kernel.
1 - I have not see that so cant help - Sorry.
2 - A lot of us are now having that problem .. and it is not particular to any ROM .. it is happening with all ICS and JB ROMS's and started only 2 - 3 weeks earlier for phones purchased more than a year ago.. am also looking for a solution on this.
3 - I have not see that so cant help - Sorry.
AW: [Q] Few issues for which I need help
1. Have you tried selecting the network manually when you are in a roaming area?
2. That's a battery issue. Maybe the battery is a bit weak and does not provide enough voltage when nearly empty. I also recommend trying another battery.
3. No clue, sorry.
Sent from my revived Galaxy Note
hi all, thanks for your replies.
I have managed to get rid of /find out the cause of these issues,
1. This is a network specific issue and was not related to phone. It has something to do with our roaming settings in network provider. !! I called them up and spoke to their technical team, so I am expecting some resolution soon
2. Bought a new battery -- problem solved (thanks guys!)
3. This is also a network related issue. ISP was blocking certain web requests !!. I changed my sim to other network and my google play just works fine. Reported to Vodafone.

[Q] Problem with wifi after lollipop update on Sprint HK M8

Hello,
My wife and I are both having similar issues with wifi after updating our phones to lillipop. We can connect to the wifi, but apps that require a login or apps that have an optional login are giving errors saying that there is no network (Network issues, no connection, etc.)
Apps that don't work with wifi: Bank apps, Amazon apps, Twitch, Feedly, Speedtest.net, etc.
Apps that do work on wifi: Chrome, YouTube, Drive, Mail apps, etc.
If we turn off the wifi, everything works fine. We both are running stock phones, I've got the HK M8, and she's got an older M7. There are times when a few of the apps will work for a few minutes, but then the issues come back. My wife's phone is also able to connect to our work wifi, when there, some of the apps that don't work at home will consistently work, but not all of them
We've both been told by HTC to do factory resets and to flash the latest stock RUU. The issue remains even after doing this. I don't really want to do the next step of sending in our phones for 7 to 10 days while they "repair" them.
I've tried everything I can think of. I've also factory reset our router and tried every wifi channel and/or security option, hoping that it is an issue with my wifi router.
Does anyone have any idea of what I can try before having to mail HTC my phone?
Thanks for any help.
Sounds exactly like the problem I had. Factory reseting the router took care of it for me though...

Hey there, i have been using an M8 for two months now and the problem that I have, which fits exactly the description of yours, is starting to annoying me. Every time I try to use these apps which need login I have to turn to mobile data to be able to do it. In my case, the issue that us affecting me the most, is with whatsapp, which even though I do can use, I cannot download media on wifi! (Neither pictures nor voice recordings).
It's a real pain in the neck to be doing this all the time, and I have two friends who also have m8s and are suffering from the same problems, so I guess it's something quite generic. Besides all the other android phones in my family work just fine with my router, so the problem is clearly mine. I think that HTC should have done something about it long time ago if it is such a common issue, considering that the price of the device is not cheap...
Anyway, my question is: have you been able to solve the problem? If you have, would you please take a min to share the solution? I would be deeply grateful!
Cheers and thanks in advance
I am using my HTC One M8 HK with lollipop update from the time they released and never had any problem with wifi. I use wifi wherever I go and no problem with anything. Try the following solutions:
1. Check the WiFi Router. Most of the times it is the problem with your router. Check if there is any restrictions or whitelist/blacklist of services.
2. You might be having some apps with whitelist/backlist running in the background. It could be your antivirus app, battery booster or Opera app, etc which does the wifi whitelist.
3. If you are using the sign-in wifi networks, make sure you signed in to the network using the browser window before opening the app.
4. If you are using the VPN (even in the wifi network) you won't be able to open the apps like Bank apps.
5. If the apps you installed are not supported in your country, you won't be able to access.
Try uninstalling and reinstalling the apps. Sometimes, when you upgrade to different OS partitions are not aligned properly. Reinstall and check.
Good luck

Problem accessing Youtube and Play Store

Hi, I desperately need some support as my device refuses to sign in in both Youtube and Play Store. I'm therefore unable to use both these apps. An error message keeps saying I'm offline and proposes to retry, but it simply never works whatever I do.
Issue has been going on since many weeks; I googles and tried many suggestions without any success.
Before I do a hard reset, has anyone an idea what this can be?
The amazing part is that my daughter's tab (Galaxy S2) is also having the same issue since some time! She has her own google account. What the heck is going on?
Thanks!

This may be an bug in the updated version of google play store or YouTube..Have you tried to sign in specific apps usning another google account you have..Also try to clear cached data of phone as well as clear data of those apps* you can also uninstall updates of those apps and force stop or disable them and after enabling again try to access*..Also might be network related issue sometimes weaken network shows such type of errors..Try to acees with high speed wifi or data with maximum signal..Even if problem exist then simply reset is last option for you..

Hi, I tried most of the solutions you're are mentioning, without any success. What I find interesting is what you wrote about weak network. I cancelled my cable connection at home some time back and using instead a 4G modem. Could that really be the culprit, knowing the coverage is medium? It sounds to me strange that such possibility exists, also I often go out and have full 4G network for hours sometimes and still it doesn't work. Interestingly enough, every about once per month it suddenly works, and I'm able to update my apps and also access my account in Youtube. It'll work for 2-3 days, until it's again the same bad. Really boring and would love to understand this issue better so as to possibly fix it. Thank you.

1)It's possible sometimes your networks proxy enforce your google id not to be sign in into specific apps you have mentioned and yes sometimes low network coverage also causes the issues like offline or sign in errors like please check network connection due wireless functionality limitations
2)I am curious about one thing if you have tried almost all the solutions found on google as well as your own, is it that much impossible for you to make backup of your current imp data and give a try to hard reset?? If i am not wrong, please give it a try because sometimes software glitches also causes the app crashes or network errors
3) Next thing sometimes your stock software gets corrupted due to some fatal malwares so many system apps as well as third party apps pretended to show errors like unfortunately process is stopped also some network related issue, so one solution you can try is to re-apply or update your current stock firmware..i.e. if update is unavailable you can fresh install same firmware version again on your phone which most of the times resolves the issue
4) As i mentioned in my first post you should give a try to any high speed mobile network like LTE or 5ghz band Wi-Fi which gives constant access to internet connection which probably help you to figure out exact issue i.e. with modems or connection your using or with your device itseld due to corrupted software
5)Please mention your device model no,country,your mobile network provider information so that it would be easy to figure out your issue
Thank you. Yes, a hard reset could solve it although I'd like to avoid it if possible. I will try ASAP on a solid wifi and see. I forgot to mention an important point: my daughter's tablet (Galaxy S2 pro) has got the same issue, and it started near about the same time like it did to me. She has her own Google ID, and she uses a different set of apps. Will report whenever I can test on a wifi.
My mobile provider is Salt Mobile here in Switzerland, and my Note 5 is a generic one bought in UAE. I run Dr. Ketan rom of about 8 months ago.

1)Ohhhk now i got, i assume you might be using Indian Variant with indian mobile network providers as per your username 'prerna'
so your device might be factory unlocked SM-N920C
2)So you should try on any faster network provider or incase wifi to check if problem is due to weak singal strength or specific with your device software integration
3) And i think you should give a try to dr.ketan's nougat rom which is based on latest nougat firmware which will might help you to overcome your issue as new base,new kernel will help you to get stable connectivity
4)If your running dr.ketans MM 6.0.1 based rom then download latest N5 nougat rom to flash
5)I know u might not new in flashing custom roms ad your running a custom one only from 8 months but once again be sure to enable 'oem unlocking' and 'usb debugging' options from developers option before flashing latest twrp version(Don't worry u can flash dr.ketans rom using any 3.0 twrp version ur running now but if latest version with stability and improvements available for your device then you can install it as per your requirement) if your running old one or before flashing nougat based N5 rom by dr.ketan

Getting the dreaded NET::ERR_CERT_AUTHORITY_INVALID message

Hi all,
Hi all, first time poster here, please highlight any indiscretions or mistakes in etiquette and I will address them going forward (forgiveness is appreciated!). I have also asked this question on the Android Central forum a couple of days back but have had no response yet.
I have a Galaxy Tab S2 - 8.0 inch screen size, 3GB RAM, 32GB Storage, Android 7.0 (Kernel Version 3.10.9-10949424). It's been absolutely fine for over a year, the only recent thing I can recall doing which may have some relevance is removal of the Airwatch Software and Agent which my previous employer used to manage devices connecting to their corporate network. No AV software is installed.
I first noticed the issue when trying to browse one of the regular newspaper sites I read in Chrome, I got the "Your connection is not private message", with the "NET::ERR_CERT_AUTHORITY_INVALID". I am not able to proceed to the site - I just get the "back to safety" option.
The problem is more wide reaching, some apps that require internet access do not work any more, Google Play thinks it is not connected to the internet. Some web sites do work however, and so do some apps. A standard Google search will not work. E-mail via the stock app and the Outlook app both work.
I searched through many websites and found the same advice and steps to attempt resolution in a number of places, I will highlight below what I have tried.
Resetting the time, from automatic to manual and back on a number of occasions, with reboots in between.
Have tried connecting to 3 different WiFi networks, all of which work fine with other Android devices and my Win 10 laptop.
Rebooted my home router.
I have cleared the Chrome cache / history multiple times.
I tried the stock browser, the same happens.
Disabled Chrome, rebooted.
Re-enabled Chrome back to it's default version.
Installed the Toaster app via an apk, but I have to admit I have no idea what to do with it.
Rebooted multiple times.
There are no user installed certificates to delete / remove.
Under Settings->General Management->Reset, I went for Reset Settings and Reset network settings, with reboots etc...
None of the above have worked, the only thing I haven't done is a factory reset, to avoid the pain of restoring everything, even with backups etc it's tedious.
Any other suggestions or advice on anything I missed would be most welcome please before I take that step, many thanks in advance.
Peter
