Hi,
So i own a nexus 7 3g and use the t-mobile data service and i am hoping you guys can help me with these random data drops i get.
I will bring my tablet to work, put it in my book bag and drive to work, and when i get to work, the data signal is gone and its disconnected from t-mobile.
The only way i know how to get data back is restarting the tablet.
I was hoping there might be another way to get data back without rebooting, or find a way for this to stop happening altogether so i dont lose data randomly like this while i travel or leave the device unattended for a few hours.
I have never owned any GSM devices besides the nexus 7 so i am not to familiar with troubleshooting or any little tinkering i need to do with a GSM device/sim card etc.
So any ideas/help will be awesome and gratefully appreciated.
Thanks in advance.

There maybe problem because of apps like juicedefender which disables network in ideal/sleep mode ,So unistalling such apps may help you , BTW Are you sure network is not an issue ? Because even i have 3G Nexus 7 , i am also facing connection issue, My networks disables automaticaly anytime, when i use Wifi it disables my Sim network connection, It means i cant use internet without wifi though its 3G model I have reported the same to my nearest Asus service centre they looking on it , They told me there will be setting for data dropping , If i able to find its solution then will PM you.

Hi
Thanks for the helpful tips. I'm pretty sure i don't have any battery saving apps, i deleted the few i did have.
I don't have any network issues. It seems it only turns off when in traveling around with it. Its really weird, and i am confused as to why it just goes away only when im traveling with it.
It does get disconnected from the internet when on wifi at home and stuff, but i still have bars in the signal icons moving and showing me that i am connected to t-mobile service.
But when i am dealing with this issues and have no data, the icon is empty and it tells me i have no service.
Maybe just toggling airplane mode might work, ill try that next time.
i tried toggleing airplane mode, no luck.
It may be the connection, but is frustrating i have to reboot every time just to get data back. Even if i toggle data in mobile data it wont work.
I have the Verizon G2. On previous phones, after I connect to wifi, i'm used to the 3g/4g logo disappearing from the notifications bar because the phone is smart enough to disable mobile data when wifi is working. I thought this was a standard stock feature.
I'm noticing on this device that those logos remain. I have a really poor signal in my office building so it switches from 3g-4g all day long. Obviously I can manually disable mobile data, or even use some apps to disable it automatically I'm sure, if that's necessary. Does anyone have a better understanding of how this works than I do?
I actually haven't noticed much impact to battery life so I'm not sure if it's something that even needs to be manually disabled? It's just confusing me why it would even bother trying to find 3g/4g signals when wifi is working and connected.
Edit: Well this convinced me to finally spend 5 minutes learning how to use Tasker and I set up a really basic profile to turn data on/off depending on my wifi connection. I'm still not sure how necessary it is but maybe I'll compare battery life with it enabled or not enabled.
Im having the same problem. Is Tasker an app u purchased? Have u noticed any difference in battery life? Thanks

data has to be on because that's how sms and mms are sent. Nothing changed between phones other than the images are showing up on this one.
I have bought my Lg G2 last saturday. I'm still researching the phone and so far it's great except one thing. Problem is when the phone is removed from charging it refuses to establish a data connection. This happened to me twice and every time in the morning after the charging.
Solution is restarting the phone. If not, it just won't connect . When i go to the settings it is turn on, but there are no arrows at the top of the screen and it doesn't work. Otherwise , after the restart it works normally all day. I keep turning it on and of and it works fine.
I think it is a software problem, since I have a network signal, but I'm not sure.
Is anyone having a similar problem?
Thanks

No, I have read about that today , but as a solution for a samsung g3 . I will try in the morning, because after the restart it works perfectly all day . Do you think it is a software problem?
Are you using different charger and cable or the originals that came with the phone?

Same here. Toggle don't work but restart works OK.

I'm using original usb cable and charger, but with extender , because of the electricity. Phone is from England, and I'm from Serbia .
After the last night charging I had the same problem, but this time I used toggle between Airplane and Data . After that everything worked fine.

Hi, i noticed this too since a couple of days... Trying To figure out what the issue is ( in possession for 2 Weeks)
I can re-establish data connection without reboot by clicking in select automatically in network operators in data /mobile networks settings. So it will reregister on the network.
Guess we need to notify lg about this issue/bug for a fix.
my sprint g2, will drop data connection occasionally when switching from wifi to 3g or from lte to 3g. so i would say there is some kind of real issue here
Same problem after rooting
I'm having the same issue, the data connection drops, mostly after going into stand-by. The problem started to occur a few days later after rooting the LG G2. I have tried the temporary solutions above with succes, but there is no final solution to it. I wonder if the device intentionally starts to brick itself after rooting, I heard the LG G2 has a lot of root checkers (says the noob).
Anyone contacted LG yet? Or tried flashing their device?
I'm having a similar issue with my G2.
After switching off wifi, data won't start.
I have to click search network then it would go on.
Would it be something to do with the modem?
When i had my Samsung gs2, I had problems with random dropouts, then I found a way to flash new modem software and all worked fine with better reception and no dropouts.
I sometimes loose network connection completely (no service) when switching from 3g to 2g or vice versa, no issue with 4g what I've seen.
Though I have this BBS, looks very alarming I must say, does anyone have similar to this:https://db.tt/aKsiw0Xe
https://db.tt/9iMHIZvm
issue fixed
hi after a recent software update (mine was D80210c-HKG-XX, build number JDQ39B,...) the data connection issue is solved for me (also made a LG support case).
But my NFC funtcion stopped working now...
Same here. Ive got this issue after rooting the G2. It cannot connect to mobile data after Im away from wifi connection. Switch airplain mode on and off helps but its annoying even if u have more email account. Another problem after rooting was freezing and restarting phone after mouse connection. But next day was everything fine and its untill today. Have anyone similar issues with custom roms?

I am rooted running Digital Dream on a Verizon VS980 with 12B radio installed. I loose data or go down to 1x all the time. I have to toggle airplane mode or reboot to re-establish 4G connection. Is there something else I can do. I love the phone but the data thing is annoying. Is the antenna really that bad in these phones?

I think and Im almost 100% sure that this must be only software problem, because when the data is runnig, it runs fast and stable. No additional inconvenience.I hope next upgrade (update) will fixt it. However Im really surprising that u have same problem on custom ROM. Im using only airplain mode to switch the data on. I needent to restart device, but it is really really annoying.
Hi everyone, as I wrote before got data connection issue while getting away from wifi. The data cannot start automatic. I found out that it happens only if GSM/ WCDMA /LTE automatic connection is selected in the settings. When I adjust GSM/ WCDMA automatic connection - everything is ok. I was trying automatic switching and runs perfect. So if u dont use LTE, better say if the WCMDA is enought for u, it can be less annoying solution as manualy turn on/ off airplain mode. I hope next update fix this issue at all. Have nice day.

It seems better (still not perfect) I wiped everything including formatting the system partition and re-installed... But thanks for the replay!
Also, I don't have to reboot ... toggleing airplane mode takes care of it, i was just saying reboot is another alternative.

This is definitely a software problem, but I have no idea how to fix it... when I first rooted everything was fine (I was on Malladus). Then I went to CM-based ROM and it was still working well.... then I updated my PRL (*228) and things started going south and I haven't been able to get it back working since.
I'm thinking of going back to Stock and starting over from scratch to see if I can fix the problem.... if anyone has an update on this issue I would greatly appreciate some advice!
potential fix for this issue?
Hi everyone. I had this phone for about 3 months. and the data connection thing has been annoying for me.. So the problem to start off with is at first I dont seem to get LTE at all during the first 2 days. I found online that the 3845#*802# or *#*#4636#*#* got me into adding LTE back into the system but problem is when I reboot. it goes back to WCDMA only or GSM WCDMA. and I lose LTE. But atleast I have LTE when I didnt reboot it. Then I found another problem which is losing data after I used LTE for a while. It won't reconnect until I reboot the phone or SOMETIMES it will return if I go into airplane mode and back. After some long research. I found this to be working for me.
So this is my story of how I got it to work for me
To start off with. This is what I am using
LG G2 D802
Android version 4.4.2
Baseband Version M8974A-AAAANAZM-1.0.190082
Kernel Version 3.4.0
Build KOT49I.D80220b
Software D80220b
My provider is Metropcs so if anyone has other issues with other providers. I don't know if this will help you.
First thing this phone needs is it has to be rooted - that part you do your own research and wont be hard since you are on XDA!!!
Then to get LTE working, you will need to type in 3845#*802# on your phone to get into the hidden menu
LTE-only ---> Modem Settings ---> RAT selection and select GSM / WCDMA / LTE Auto (will display SUCCESS) tap OK
This will give you LTE from the phone but it will not give you this option in your Mobile Networks / Network mode section (Preferred network mode) Atleast it didn't display it for me.
For my phone I had to edit the build.prop file for it to show it in the preferred network mode list.
In the build.prop file. You will have to look for this line and change the 9 to a 11. I've also saw some post about it being not a 9 and have to change to 12 for some networks. ALSO MAKE SURE YOU DO NOT CHANGE IT TO A NUMBER 0. It will crash the phone.
From
ro.telephony.default_network=9
To
ro.telephony.default_network=11
After this I got me LTE connection but issue with the lost of settings after reboot started. So next part helps with the reconnection after reboot. I got this from a post in XDA So give credit to the person that posted this. Sorry if I dont have it handy as I wrote this
- Root
- Install and activate Xposed fw
- Install and activate Intelli3G module
- In build.prop change ro.telephony.default_network=9 from 9 to 11
- Create a Tasker profile of type Event -> System -> Device Boot
- Associate the profile to a new Task of type Misc -> Send Intent
- Configure the task by setting in the "Action" field the value "action.intelli3g.CHANGE_NETWORK_TYPE" and in the first "Extra" field set the value "extra.intelli3g.NETWORK_TYPE:10"
Doing this got my reconnection after reboot fixed. and LAST is the problem of randomly losing data connect until I reboot the phone. and after a long test.. This is my result. The phone lost connection due to trying to connect to LTE with non existing band. I don't know too much about those but from my testing. This is how I made my phone worked and it has been working for the last 2 weeks without any issue.
Go back into the hidden menu with 3845#*802#
LTE-only --> Modem Settings --> LTE Band Selection
Here you will see a Band with a number.
MetroPCS supports band 2, 4, 5 and 12
Since this phone doesnt have 12. You only select 2, 4 and 5 then just push back until the hidden menu closes.
Other providers. I dont know what band that they use. but i am guessing if you only select the bands that company supports. You might not have that issue with losing data anymore.
Please press thanks if this works for you.
I have been having issue since I switched from att with my phone auto connecting to their hotspots which I can no longer use. My issue is I cant seem to delete the saved wifi network or even modify it to prevent it from being used.
I have tried factory resets but it seems to be populated by my google backup as it was on the phone immediately. Now Im not rooted and don't think I can be as im on the newest OTA update as I wanted lollipop and honestly I had stability issues with being rooted as both s health and ISIS wouldn't work.
Is there anything I can do to remove this dang wifi network as its driving me crazy.

When you're connected to AT&T WiFi go into WiFi settings, tap on the network, and click "Forget."
So I find that when at home my device will switch between mobile and wifi calling when in a call. The mobile signal here is pretty poor, so people struggle to hear me, making my preference Wifi calling.
What I found is that the device seems to prefer mobile rather than wifi and there is no way to change this. The only way to force it is to switch on airplane mode, then activate the wireless. However I then need to switch off airplane mode each time i leave the house.
After searching for a fix for months now, i appear to have stumbled in to a fix accidentally when fixing something else.
Basically, i disabled all the Bixby stuff using lucky patcher (Titanium backup no longer works for me). Once i did this, i found my calls ALL suddenly go over wifi! Im not sure why or if it's a coincidence, but it's definitely working.
Hoping this helps others looking to fix this.
